CASE Endometriosis pain increases despite hormonal treatment
A 25-year-old woman (G0) with severe dysmenorrhea had a laparoscopy showing endometriosis in the cul-de-sac and a peritoneal window near the left uterosacral ligament. Biopsy of a cul-de-sac lesion showed endometriosis on histopathology. The patient was treated with a continuous low-dose estrogen-progestin contraceptive. Initially, the treatment helped relieve her pain symptoms. Over the next year, while on that treatment, her pain gradually increased in severity until it was disabling. At an office visit, the primary clinician renewed the estrogen-progestin contraceptive for another year, even though it was not relieving the patient’s pain. The patient sought a second opinion.
We are the experts in the management of pelvic pain caused by endometriosis
Women’s health clinicians are the specialists best trained to care for patients with severe pain caused by endometriosis. Low-dose continuous estrogen-progestin contraceptives are commonly prescribed as a first-line hormonal treatment for pain caused by endometriosis. My observation is that estrogen-progestincontraceptives are often effective when initially prescribed, but with continued use over years, pain often recurs. Estrogen is known to stimulate endometriosis disease activity. Progestins at high doses suppress endometriosis disease activity. However, endometriosis implants often manifest decreased responsiveness to progestins, permitting the estrogen in the combination contraceptive to exert its disease-stimulating effect.1,2 I frequently see women with pelvic pain caused by endometriosis, who initially had a significant decrease in pain with continuous estrogen-progestin contraceptive treatment but who develop increasing pain with continued use of the medication. In this clinical situation, it is useful to consider stopping the estrogen-progestin therapy and to prescribe a hormone with a different mechanism of action (TABLE).
Progestin-only medications
Progestin-only medications are often effective in the treatment of pain caused by endometriosis. High-dose progestin-only medications suppress pituitary secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), thereby suppressing ovarian synthesis of estrogen, resulting in low circulating levels of estrogen. This removes the estrogen stimulus that exacerbates endometriosis disease activity. High-dose progestins also directly suppress cellular activity in endometriosis implants. High-dose progestins often overcome the relative resistance of endometriosis lesions to progestin suppression of disease activity. Hence, high-dose progestin-only medications have two mechanisms of action: suppression of estrogen synthesis through pituitary suppression of LH and FSH, and direct inhibition of cellular activity in the endometriosis lesions. High-dose progestin-only treatments include:
- oral norethindrone acetate 5 mg daily
- oral medroxyprogesterone acetate (MPA) 20 to 40 mg daily
- subcutaneous, or depot MPA
- levonorgestrel-releasing intrauterine device (LNG-IUD).
In my practice, I frequently use oral norethindrone acetate 5 mg daily to treat pelvic pain caused by endometriosis. In one randomized trial, 90 women with pelvic pain and rectovaginal endometriosis were randomly assigned to treatment with norethindrone acetate 2.5 mg daily or an estrogen-progestin contraceptive. After 12 months of treatment, satisfaction with treatment was reported by 73% and 62% of the women in the norethindrone acetate and estrogen-progestin groups, respectively.3 The most common adverse effects reported by women taking norethindrone acetate were weight gain (27%) and decreased libido (9%).
Oral MPA at doses of 30 mg to 100 mg daily has been reported to be effective for the treatment of pelvic pain caused by endometriosis. MPA treatment can induce atrophy and pseudodecidualization in endometrium and endometriosis implants. In my practice I typically prescribe doses in the range of 20 mg to 40 mg daily. With oral MPA treatment, continued uterine bleeding may occur in up to 30% of women, somewhat limiting its efficacy.4–7
Subcutaneous and depot MPA have been reported to be effective in the treatment of pelvic pain caused by endometriosis.4,8 In some resource-limited countries, depot MPA may be the most available progestin for the treatment of pelvic pain caused by endometriosis.
The LNG-IUD, inserted after surgery for endometriosis, has been reported to result in decreased pelvic pain in studies with a modest number of participants.9–11
GnRH analogue medications
Gonadotropin-releasing hormone (GnRH) analogues, including both GnRH agonists (nafarelin, leuprolide, and goserelin) and GnRH antagonists (elagolix) reduce pelvic pain caused by endometriosis by suppressing pituitary secretion of LH and FSH, thereby reducing ovarian synthesis of estradiol. In the absence of estradiol stimulation, cellular activity in endometriosis lesions decreases and pain symptoms improve. In my practice, I frequently use either nafarelin12 or leuprolide acetate depot plus norethindrone add-back.13 I generally avoid the use of leuprolide depot monotherapy because in many women it causes severe vasomotor symptoms.
At standard doses, nafarelin therapy generally results in serum estradiol levels in the range of 20 to 30 pg/mL, a “sweet spot” associated with modest vasomotor symptoms and reduced cellular activity in endometriosis implants.12,14 In many women who become amenorrheic on nafarelin two sprays daily, the dose can be reduced with maintenance of pain control and ovarian suppression.15 Leuprolide acetate depot monotherapy results in serum estradiol levels in the range of 5 to 10 pg/mL, causing severe vasomotor symptoms and reduction in cellular activity in endometriosis lesions. To reduce the adverse effects of leuprolide acetate depot monotherapy, I generally initiate concomitant add-back therapy with norethindrone acetate.13 A little recognized pharmacokinetic observation is that a very small amount of norethindrone acetate, generally less than 1%, is metabolized to ethinyl estradiol.16
The oral GnRH antagonist, elagolix, 150 mg daily for up to 24 months or 200 mg twice daily for 6 months, was approved by the US Food and Drug Administration (FDA) in July 2018. It is now available in pharmacies. Elagolix treatment results in significant reduction in pain caused by endometriosis, but only moderately bothersome vasomotor symptoms.17,18 Elagolix likely will become a widely used medication because of the simplicity of oral administration, efficacy against endometriosis, and acceptable adverse-effect profile. A major disadvantage of the GnRH analogue-class of medications is that they are more expensive than the progestin medications mentioned above. Among the GnRH analogue class of medications, elagolix and goserelin are the least expensive.
Androgens
Estrogen stimulates cellular activity in endometriosis lesions. Androgen and high-dose progestins inhibit cellular activity in endometriosis lesions. Danazol, an attenuated androgen and a progestin is effectivein treating pelvic pain caused by endometriosis.19,20 However, many women decline to use danazol because it is often associated with weight gain. As an androgen, danazol can permanently change a woman’s voice pitch and should not be used by professional singers or speech therapists.
Aromatase Inhibitors
Estrogen is a critically important stimulus of cell activity in endometriosis lesions. Aromatase inhibitors, which block the synthesis of estrogen, have been explored in the treatment of endometriosis that has proven to be resistant to other therapies. Although the combination of an aromatase inhibitor plus a high-dose progestin or GnRH analogue may be effective, more data are needed before widely using the aromatase inhibitors in clinical practice.21
Don’t get stuck in a rut
When treating pelvic pain caused by endometriosis, if the patient’s hormone regimen is not working, prescribe a medication from another class of hormones. In the case presented above, a woman with pelvic pain and surgically proven endometriosis reported inadequate control of her pain symptoms with a continuous estrogen-progestin medication. Her physician prescribed another year of the same estrogen-progestin medication. Instead of renewing the medication, the physician could have offered the patient a hormone medication from another drug class: 1) progestin only, 2) GnRH analogue, or 3) danazol. By using every available hormonal agent, physicians will improve the treatment of pelvic pain caused by endometriosis. Millions of women in our country have pelvic pain caused by endometriosis. They are counting on us, women’s health specialists, to effectively treat their disease.

Occipital Nerve Blocks May Be an Effective Option for Acute Migraine in the Emergency Room
When IV metoclopramide fails to relieve acute migraine in the emergency department, greater occipital nerve block may be an effective treatment.
SAN FRANCISCO—Greater occipital nerve blocks with bupivacaine may be an effective treatment for patients with acute migraine in the emergency department who continue to experience moderate or severe headache after administration of intravenous metoclopramide, according to a presentation at the 60th Annual Scientific Meeting of the American Headache Society.
Greater occipital nerve block is thought to be an effective treatment for acute migraine, although no randomized efficacy data have been published for this indication. Benjamin W. Friedman, MD, Professor of Emergency Medicine, Montefiore Medical Center, Albert Einstein College of Medicine, Bronx, New York, and colleagues hypothesized that bilateral greater occipital nerve block with bupivacaine would provide greater rates of headache freedom than a sham injection among a population of emergency department patients who reported persistence of moderate or severe headache despite standard treatment with intravenous metoclopramide.
Dr. Friedman and colleagues conducted a randomized, sham-controlled trial of bilateral greater occipital nerve blocks with bupivacaine in two urban emergency departments. Patients with acute migraine who reported persistence of a moderate or severe headache for at least one hour or longer after treatment with 10 mg of intravenous metoclopramide were randomized to bilateral greater occipital nerve block with a total of 6 cc of 0.5% bupivacaine or bilateral intradermal scalp injection with a total of 1 cc of 0.5% bupivacaine. The primary outcome was complete headache freedom 30 minutes after the injection. An important secondary outcome was sustained headache relief, defined as achieving a headache level of mild or none in the emergency department and maintaining a level of mild or no headache without the use of any additional medication for 48 hours.
Over a 32-month period, 76 patients were screened for participation and 28 were enrolled, of whom 15 received sham injection and 13 received greater occipital nerve block. The primary outcome, headache freedom at 30 minutes, was achieved by none of the patients in the sham arm and by four patients (31%) in the nerve block arm. The secondary outcome, sustained headache relief for 48 hours, was reported by none of the patients who received sham and by three of the patients (23%) who received greater occipital nerve blocks. Reported side effects did not differ substantially between the two groups.

Fremanezumab May Reduce Medication Overuse in Migraineurs
A reduction in medication overuse is apparent after four weeks of treatment.
SAN FRANCISCO—Treatment with fremanezumab is associated with reduced overuse of acute medications and a corresponding decrease in days on which a patient uses acute medications, according to a phase III study described at the 60th Annual Scientific Meeting of the American Headache Society.
The overuse of acute or symptomatic headache medications (eg, triptans, ergot derivatives, opioids, and combination analgesics) can cause medication overuse headache (MOH). Chronic migraine is often accompanied by MOH, and the prevention of MOH is one of the main goals in the preventive treatment of migraine.
Fremanezumab, a fully humanized monoclonal antibody that selectively targets calcitonin gene-related peptide, reduced the frequency and severity of headaches in patients with chronic migraine who participated in clinical trials. Stephen D. Silberstein, MD, Director of the Headache Center at Thomas Jefferson University Hospital in Philadelphia, and colleagues assessed the effect of fremanezumab, compared with placebo, on medication overuse and acute headache medication use in patients with chronic migraine.
Comparing Two Fremanezumab Doses With Placebo
The investigators conducted a multicenter, randomized, double-blind, placebo-controlled, phase III study, during which they randomized eligible patients with chronic migraine in equal groups to receive subcutaneous injections of fremanezumab quarterly dosing (ie, 675 mg at baseline and placebo at Weeks 4 and 8), fremanezumab monthly dosing (ie, 675 mg at baseline and 225 mg at Weeks 4 and 8), or placebo at each time point over a 12-week treatment period. Dr. Silberstein’s group defined medication overuse as the use of acute headache medication on 15 or more days, the use of migraine-specific acute medication on 10 or more days, or the use of combination medications for headache on 10 or more days during the 28-day baseline period.
In a post hoc analysis, the researchers assessed the proportion of patients who reverted from overusing medications at baseline to not overusing medications at Week 12, as well as the change from baseline in the number of days of acute headache medication use among these patients. Analyses were performed using data for all randomized patients who received at least one dose of study drug and had at least 10 days of postbaseline efficacy assessments on the primary end point.
Fremanezumab Was More Likely to Reduce Overuse
At baseline, the number of patients with medication overuse was 201 in the quarterly arm, 198 in the monthly arm, and 188 in the placebo arm. Among these participants, significantly more fremanezumab-treated patients reported no medication overuse during the 12-week treatment period. The number of patients reporting no medication overuse was 111 (55%) in the quarterly arm, 120 (61%) in the monthly arm, and 87 (46%) in the placebo arm. The investigators observed a response to treatment as early as Week 4 (102 [51%] quarterly patients, 107 [54%] monthly patients, and 73 [39%] controls).
Among the patients who responded to treatment over the 12-week treatment period, the baseline number of days with medication overuse was similar across treatment groups (approximately 16.6). Within this population, fremanezumab treatment significantly reduced the number of days of acute headache medication use over the 12-week treatment period by nine in the quarterly arm and 8.9 in the monthly arm, compared with 7.1 among controls.

Obesity: When to consider medication
Modest weight loss of 5% to 10% among patients who are overweight or obese can result in a clinically relevant reduction in cardiovascular (CV) disease risk.1 This amount of weight loss can increase insulin sensitivity in adipose tissue, liver, and muscle, and have a positive impact on blood sugar, blood pressure, triglycerides, and high-density lipoprotein cholesterol.1,2
All patients who are obese or overweight with increased CV risk should be counseled on diet, exercise, and other behavioral interventions.3 Weight loss secondary to lifestyle modification alone, however, leads to adaptive physiologic responses, which increase appetite and reduce energy expenditure.4–6
Pharmacotherapy can counteract this metabolic adaptation and lead to sustained weight loss. Antiobesity medication can be considered if a patient has a body mass index (BMI) ≥30 kg/m2 or ≥27 kg/m2 with obesity-related comorbidities such as hypertension, type 2 diabetes, dyslipidemia, or obstructive sleep apnea.3,7
For patients with a body mass index (BMI) ≥30 kg/m2 or BMI ≥27 kg/m2 with weight-related comorbidities:
- Consider antiobesity pharmacotherapy when diet, exercise, and behavior modification do not produce sufficient weight loss. A
- Continue an antiobesity medication if it is deemed effective and well tolerated.A
A Good-quality patient-oriented evidence
B Inconsistent or limited-quality patient-oriented evidence
C Consensus, usual practice, opinion, disease-oriented evidence, case series
Until recently, there were few pharmacologic options approved by the US Food and Drug Administration (FDA) for the management of obesity. The mainstays of treatment were phentermine (Adipex-P, Ionamin, Suprenza) and orlistat (Alli, Xenical). Since 2012, however, 4 agents have been approved as adjuncts to a reduced-calorie diet and increased physical activity for long-term weight management.8,9 Phentermine/topiramate extended-release (ER) (Qsymia) and lorcaserin (Belviq) were approved in 2012,10,11 and naltrexone sustained release (SR)/bupropion SR (Contrave) and liraglutide 3 mg (Saxenda) were approved in 201412,13 (TABLE9,14–39). These medications have the potential to not only limit weight gain but also promote weight loss and, thus, improve blood pressure, cholesterol, glucose, and insulin.40
Despite the growing obesity epidemic and the availability of several additional medications for chronic weight management, use of antiobesity pharmacotherapy has been limited. Barriers to use include inadequate training of health care professionals, poor insurance coverage for new agents, and low reimbursement for office visits to address weight.41
In addition, the number of obesity medicine specialists, while increasing, is still not sufficient. Therefore, it is imperative for other health care professionals—including ObGyns—to be aware of the treatment options available to patients who are overweight or obese and to be adept at using them.
In this review, we present 4 cases that depict patients who could benefit from the addition of antiobesity pharmacotherapy to a comprehen‑sive treatment plan that includes diet, physical activity, and behavioral modification.
CASE 1 Young obese woman is unable to lose weight
A 27-year-old woman with obesity (BMI 33 kg/m2),hyperlipidemia, and migraine headaches, pre‑sents for weight management. Despite a calorie-reduced diet and 200 minutes per week of exercise for the past 6 months, she has been unable to lose weight. The only medications she is taking are oral contraceptive pills and sumatriptan, as needed. She suffers from migraines 3 times a month and has no anxiety. Laboratory test results are normal with the exception of an elevated low-density lipoprotein (LDL) level.
Which medication is an appropriate next step for this patient?
Ask 2 important questions
When considering an antiobesity agent for any patient, there are 2 important questions to ask:
- Are there contraindications, drug-drug interactions, or undesirable adverse effects associated with this medication that could be problematic for the patient?
- Can this medication improve other symptoms or conditions the patient has?
In addition, see “Before prescribing antiobesity medication . . .” below.
Have a frank discussion with the patient and be sure to cover the following points:
The rationale for pharmacologic treatment is to counteract adaptive physiologic responses, which increase appetite and reduce energy expenditure, in response to diet-induced weight loss.
Antiobesity medication is only one component of a comprehensive treatment plan, which also includes diet, physical activity, and behavior modification.
Antiobesity agents are intended for long-term use, as obesity is a chronic disease. If/when you stop the medication, there may be some weight regain, similar to an increase in blood pressure after discontinuing an antihypertensive agent.
Because antiobesity medications improve many parameters including glucose/hemoglobin A1c, lipids, blood pressure, and waist circumference, it is possible that the addition of one antiobesity medication can reduce, or even eliminate, the need for several other medications.
Remember that many patients who present for obesity management have experienced weight bias. It is important to not be judgmental, but rather explain why obesity is a chronic disease. If patients understand the physiology of their condition, they will understand that their limited success with weight loss in the past is not just a matter of willpower. Lifestyle change and weight loss are extremely difficult, so it is important to provide encouragement and support for ongoing behavioral modification.
Phentermine/topiramate ER
Phentermine/topiramate ER is a good first choice for this young patient with class I (BMI 30–34.9 kg/m2) obesity and migraines, as she can likely tolerate a stimulant and her migraines might improve with topiramate. Before starting the medication, ask about insomnia and nephrolithiasis in addition to anxiety and other contraindications (ie, glaucoma, hyperthyroidism, recent monoamine oxidase inhibitor use, or a known hypersensitivity or idiosyncrasy to sympathomimetic amines).23 The most common adverse events reported in phase III trials were dry mouth, paresthesia, and constipation.24–26
Not for pregnant women. Women of childbearing age must have a negative pregnancy test before starting phentermine/topiramate ER and every month while taking the medication. The FDA requires a Risk Evaluation and Mitigation Strategy (REMS) to inform prescribers and patients about the increased risk of congenital malformation, specifically orofacial clefts, in infants exposed to topiramate during the first trimester of pregnancy.42 REMS focuses on the importance of pregnancy prevention, the consistent use of birth control, and the need to discontinue phentermine/topiramate ER immediately if pregnancy occurs.
Flexible dosing. Phentermine/topiramate ER is available in 4 dosages: phentermine 3.75 mg/topiramate 23 mg ER; phentermine 7.5 mg/topiramate 46 mg ER; phentermine 11.25 mg/topiramate 69 mg ER; and phentermine 15 mg/topiramate 92 mg ER. Gradual dose escalation minimizes risks and adverse events.23
Monitor patients frequently to evaluate for adverse effects and ensure adherence to diet, exercise, and lifestyle modifications. If weight loss is slower or less robust than expected, check for dietary indiscretion, as medications have limited efficacy without appropriate behavioral changes.
Discontinue phentermine/topiramate ER if the patient does not achieve 5% weight loss after 12 weeks on the maximum dose, as it is unlikely that she will achieve and sustain clinically meaningful weight loss with continued treatment.23 In this case, consider another agent with a different mechanism of action. Any of the other antiobesity medications could be appropriate for this patient.
CASE 2 Overweight woman with comorbidities
A 52-year-old overweight woman (BMI 29 kg/m2)with type 2 diabetes, hyperlipidemia, osteoarthritis, and glaucoma has recently hit a plateau with her weight loss. She lost 45 lb secondary to diet and exercise, but hasn’t been able to lose any more. She also struggles with constant hunger. Her medications include metformin 1,000 mg twice per day, atorvastatin 10 mg/d, and occasional acetaminophen/oxycodone for knee pain until she undergoes a left knee replacement. Laboratory values are normal except for a hemoglobin A1c of 7.2%.
The patient is afraid of needles and cannot tolerate stimulants due to anxiety. Which medication is an appropriate next step for this patient?
What are good choices for this patient?
Lorcaserin is a good choice for this patient who is overweight and has several weight-related comorbidities. She has worked hard to lose a significant number of pounds and is now at high risk of regaining them. That’s because her appetite has increased with her new exercise regimen, but her energy expenditure has decreased secondary to metabolic adaptation.
Narrowing the field. Naltrexone SR/bupropion SR cannot be used because of her opioid use. Phentermine/topiramate ER is contraindicated for patients with glaucoma, and liraglutide 3 mg is not appropriate given the patient’s fear of needles.
She could try orlistat, especially if she struggles with constipation, but the gastrointestinal adverse effects are difficult for many patients to tolerate. While not an antiobesity medication, a sodium-glucose co-transporter 2 (SGLT2) inhibitor could be prescribed for her diabetes and also may promote weight loss.43
An appealing choice. The glucose-lowering effect of lorcaserin could provide an added benefit for the patient. The BLOOMDM (Behavioral modification and lorcaserin for overweight and obesity management in diabetes mellitus) study reported a mean reduction in hemoglobin A1c of 0.9% in the treatment group compared with a 0.4% reduction in the placebo group,30 and the effect of lorcaserin on A1c appeared to be independent of weight loss.
Mechanism of action: Cause for concern? Although lorcaserin selectively binds to serotonin 5-HT2C receptors, the theoretical risk of cardiac valvulopathy was evaluated in phase III studies, as fenfluramine, a 5-HT2B-receptor agonist, was withdrawn from the US market in 1997 for this reason.44 Both the BLOOM (Behavioral modification and lorcaserin for overweight and obesity management) and BLOSSOM (Behavioral modification and lorcaserin second study for obesity management) studies found that lorcaserin did not increase the incidence of FDA-defined cardiac valvulopathy.28,29
Formulations/adverse effects. Lorcaserin is available in 2 formulations: 10-mg tablets, which are taken twice daily, or 20-mg XR tablets, which are taken once daily. Both are generally well tolerated.27,45 The most common adverse event reported in phase III trials was headache.28,30,43 Discontinue lorcaserin if the patient does not lose 5% of her initial weight after 12 weeks, as weight loss at this stage is a good predictor of longer-term success.46
Some patients don’t respond. Interestingly, a subset of patients do not respond to lorcaserin. The most likely explanation for different responses to the medication is that there are many causes of obesity, only some of which respond to 5-HT2C agonism. Currently, we do not perform pharmacogenomics testing before prescribing lorcaserin, but perhaps an inexpensive test to identify responders will be available in the future.
CASE 3 A preoccupation with food
A 38-year-old woman with obesity (BMI 42 kg/m2),obstructive sleep apnea, gastroesophageal reflux disease, and depression is eager to get better control over her weight. Her medications include lansoprazole 30 mg/d and a multivitamin. She reports constantly thinking about food and not being able to control her impulses to buy large quantities of unhealthy snacks. She is so preoccupied by thoughts of food that she has difficulty concentrating at work.
The patient smokes a quarter of a pack of cigarettes daily, but she is ready to quit. She views bariatric surgery as a “last resort” and has no anxiety, pain, or history of seizures. Which medication is appropriate for this patient?
Discuss all options
This patient with class III obesity (BMI ≥40 kg/m2) is eligible for bariatric surgery; however, she is not interested in pursuing it at this time. It is important to discuss all of her options before deciding on a treatment plan. For patients like this, who would benefit from more than modest weight loss, consider a multidisciplinary approach including lifestyle modifications, pharmacotherapy, devices (eg, an intragastric balloon), and/or surgery. You would need to make clear to the patient that she may still be eligible for insurance coverage for surgery if she changes her mind after pursuing other treatments as long as her BMI remains ≥35 kg/m2 with obesity-related comorbidities.
Naltrexone SR/bupropion SR is a good choice for this patient because she describes debilitating cravings and addictive behavior surrounding food. Patients taking naltrexone SR/bupropion SR in the Contrave Obesity Research (COR)-I and COR-II phase III trials experienced a reduced frequency of food cravings, reduced difficulty in resisting food cravings, and an increased ability to control eating compared with those assigned to placebo.32,33
Added benefits. Bupropion also could help this patient quit smoking and improve her mood, as it is FDA-approved for smoking cessation and depression. She denies anxiety and seizures, so bupropion is not contraindicated. Even if a patient denies a history of seizure, ask about any conditions that predispose to seizures, such as anorexia nervosa or bulimia or the abrupt discontinuation of alcohol, benzodiazepines, barbiturates, or antiepileptic drugs.
Opioid use. Although the patient denies pain, ask about potential opioid use, as naltrexone is an opioid receptor antagonist. Patients should be informed that opioids may be ineffective if they are required unexpectedly (eg, for trauma) and that naltrexone SR/bupropion SR should be withheld for any planned surgical procedure potentially requiring opioid use.
Other options. While naltrexone SR/bupropion SR is the most appropriate choice for this patient because it addresses her problematic eating behaviors while potentially improving mood and assisting with smoking cessation, phentermine/topiramate ER, lorcaserin, and liraglutide 3 mg also could be used and certainly should be tried if naltrexone SR/bupropion SR does not produce the desired weight loss.
Adverse effects. Titrate naltrexone SR/bupropion SR slowly to the treatment dose to minimize risks and adverse events.31 The most common adverse effects reported in phase III trials were nausea, constipation, and headache.34,35,45,46 Discontinue naltrexone SR/bupropion SR if the patient does not achieve 5% weight loss at 16 weeks (after 12 weeks at the maintenance dose).31
CASE 4 Regaining weight after gastric bypass
A 65-year-old woman with obesity (BMI 39 kg/m2)who underwent Roux-en-Y gastric bypass surgery and who has type 2 diabetes, congestive heart failure, coronary artery disease, hypertension, and hyperlipidemia, remains concerned about her weight. She lost 100 lb following surgery and maintained her weight for 3 years, but then regained 30 lb. She comes in for an office visit because she is concerned about her increasing blood sugar and wants to prevent further weight gain. Her medications include metformin 1,000 mg twice per day, lisinopril 5 mg/d, carvedilol 12.5 mg twice per day, simvastatin 20 mg/d, and aspirin 81 mg/d. Laboratory test results are normal except for a hemoglobin A1c of 8%. She denies pancreatitis and a personal or family history of thyroid cancer.
Which medication is an appropriate next step for this patient?
Pharmacotherapy is an option
Pharmacotherapy is a great option for this patient, who is regaining weight following bariatric surgery. Phentermine/topiramate ER is the only medication that would be contraindicated because of her heart disease. Lorcaserin and naltrexone SR/bupropion SR could be considered, but liraglutide 3 mg is the most appropriate option, given her need for further glucose control.
Furthermore, the recent LEADER (Liraglutide effect and action in diabetes: evaluation of CV outcome results) trial reported a significant mortality benefit with liraglutide 1.8 mg/d among patients with type 2 diabetes and high CV risk.47 The study found that liraglutide was superior to placebo in reducing CV events.
Contraindications. Ask patients about a history of pancreatitis before starting liraglutide 3 mg, given the possible increased risk. In addition, liraglutide is contraindicated in patients with a personal or family history of medullary thyroid carcinoma or in patients with multiple endocrine neoplasia syndrome type 2. Thyroid C-cell tumors have been found in rodents given supratherapeutic doses of liraglutide48; however, there is no evidence of liraglutide causing C-cell tumors in humans.
For patients taking a medication that can cause hypoglycemia, such as insulin or a sulfonylurea, monitor blood sugar and consider reducing the dose of that medication when starting liraglutide.
Administration and titration. Liraglutide is injected subcutaneously once daily. The dose is titrated up weekly to reduce gastrointestinal symptoms.36 The most common adverse effects reported in phase III trials were nausea, diarrhea, and constipation.37–39Discontinue liraglutide 3 mg if the patient does not lose at least 4% of baseline body weight after 16 weeks.49

Modest weight loss of 5% to 10% among patients who are overweight or obese can result in a clinically relevant reduction in cardiovascular (CV) disease risk.1 This amount of weight loss can increase insulin sensitivity in adipose tissue, liver, and muscle, and have a positive impact on blood sugar, blood pressure, triglycerides, and high-density lipoprotein cholesterol.1,2
All patients who are obese or overweight with increased CV risk should be counseled on diet, exercise, and other behavioral interventions.3 Weight loss secondary to lifestyle modification alone, however, leads to adaptive physiologic responses, which increase appetite and reduce energy expenditure.4–6
Pharmacotherapy can counteract this metabolic adaptation and lead to sustained weight loss. Antiobesity medication can be considered if a patient has a body mass index (BMI) ≥30 kg/m2 or ≥27 kg/m2 with obesity-related comorbidities such as hypertension, type 2 diabetes, dyslipidemia, or obstructive sleep apnea.3,7
For patients with a body mass index (BMI) ≥30 kg/m2 or BMI ≥27 kg/m2 with weight-related comorbidities:
- Consider antiobesity pharmacotherapy when diet, exercise, and behavior modification do not produce sufficient weight loss. A
- Continue an antiobesity medication if it is deemed effective and well tolerated.A
A Good-quality patient-oriented evidence
B Inconsistent or limited-quality patient-oriented evidence
C Consensus, usual practice, opinion, disease-oriented evidence, case series
Until recently, there were few pharmacologic options approved by the US Food and Drug Administration (FDA) for the management of obesity. The mainstays of treatment were phentermine (Adipex-P, Ionamin, Suprenza) and orlistat (Alli, Xenical). Since 2012, however, 4 agents have been approved as adjuncts to a reduced-calorie diet and increased physical activity for long-term weight management.8,9 Phentermine/topiramate extended-release (ER) (Qsymia) and lorcaserin (Belviq) were approved in 2012,10,11 and naltrexone sustained release (SR)/bupropion SR (Contrave) and liraglutide 3 mg (Saxenda) were approved in 201412,13 (TABLE9,14–39). These medications have the potential to not only limit weight gain but also promote weight loss and, thus, improve blood pressure, cholesterol, glucose, and insulin.40
Despite the growing obesity epidemic and the availability of several additional medications for chronic weight management, use of antiobesity pharmacotherapy has been limited. Barriers to use include inadequate training of health care professionals, poor insurance coverage for new agents, and low reimbursement for office visits to address weight.41
In addition, the number of obesity medicine specialists, while increasing, is still not sufficient. Therefore, it is imperative for other health care professionals—including ObGyns—to be aware of the treatment options available to patients who are overweight or obese and to be adept at using them.
In this review, we present 4 cases that depict patients who could benefit from the addition of antiobesity pharmacotherapy to a comprehen‑sive treatment plan that includes diet, physical activity, and behavioral modification.
CASE 1 Young obese woman is unable to lose weight
A 27-year-old woman with obesity (BMI 33 kg/m2),hyperlipidemia, and migraine headaches, pre‑sents for weight management. Despite a calorie-reduced diet and 200 minutes per week of exercise for the past 6 months, she has been unable to lose weight. The only medications she is taking are oral contraceptive pills and sumatriptan, as needed. She suffers from migraines 3 times a month and has no anxiety. Laboratory test results are normal with the exception of an elevated low-density lipoprotein (LDL) level.
Which medication is an appropriate next step for this patient?
Ask 2 important questions
When considering an antiobesity agent for any patient, there are 2 important questions to ask:
- Are there contraindications, drug-drug interactions, or undesirable adverse effects associated with this medication that could be problematic for the patient?
- Can this medication improve other symptoms or conditions the patient has?
In addition, see “Before prescribing antiobesity medication . . .” below.
Have a frank discussion with the patient and be sure to cover the following points:
The rationale for pharmacologic treatment is to counteract adaptive physiologic responses, which increase appetite and reduce energy expenditure, in response to diet-induced weight loss.
Antiobesity medication is only one component of a comprehensive treatment plan, which also includes diet, physical activity, and behavior modification.
Antiobesity agents are intended for long-term use, as obesity is a chronic disease. If/when you stop the medication, there may be some weight regain, similar to an increase in blood pressure after discontinuing an antihypertensive agent.
Because antiobesity medications improve many parameters including glucose/hemoglobin A1c, lipids, blood pressure, and waist circumference, it is possible that the addition of one antiobesity medication can reduce, or even eliminate, the need for several other medications.
Remember that many patients who present for obesity management have experienced weight bias. It is important to not be judgmental, but rather explain why obesity is a chronic disease. If patients understand the physiology of their condition, they will understand that their limited success with weight loss in the past is not just a matter of willpower. Lifestyle change and weight loss are extremely difficult, so it is important to provide encouragement and support for ongoing behavioral modification.
Phentermine/topiramate ER
Phentermine/topiramate ER is a good first choice for this young patient with class I (BMI 30–34.9 kg/m2) obesity and migraines, as she can likely tolerate a stimulant and her migraines might improve with topiramate. Before starting the medication, ask about insomnia and nephrolithiasis in addition to anxiety and other contraindications (ie, glaucoma, hyperthyroidism, recent monoamine oxidase inhibitor use, or a known hypersensitivity or idiosyncrasy to sympathomimetic amines).23 The most common adverse events reported in phase III trials were dry mouth, paresthesia, and constipation.24–26
Not for pregnant women. Women of childbearing age must have a negative pregnancy test before starting phentermine/topiramate ER and every month while taking the medication. The FDA requires a Risk Evaluation and Mitigation Strategy (REMS) to inform prescribers and patients about the increased risk of congenital malformation, specifically orofacial clefts, in infants exposed to topiramate during the first trimester of pregnancy.42 REMS focuses on the importance of pregnancy prevention, the consistent use of birth control, and the need to discontinue phentermine/topiramate ER immediately if pregnancy occurs.
Flexible dosing. Phentermine/topiramate ER is available in 4 dosages: phentermine 3.75 mg/topiramate 23 mg ER; phentermine 7.5 mg/topiramate 46 mg ER; phentermine 11.25 mg/topiramate 69 mg ER; and phentermine 15 mg/topiramate 92 mg ER. Gradual dose escalation minimizes risks and adverse events.23
Monitor patients frequently to evaluate for adverse effects and ensure adherence to diet, exercise, and lifestyle modifications. If weight loss is slower or less robust than expected, check for dietary indiscretion, as medications have limited efficacy without appropriate behavioral changes.
Discontinue phentermine/topiramate ER if the patient does not achieve 5% weight loss after 12 weeks on the maximum dose, as it is unlikely that she will achieve and sustain clinically meaningful weight loss with continued treatment.23 In this case, consider another agent with a different mechanism of action. Any of the other antiobesity medications could be appropriate for this patient.
CASE 2 Overweight woman with comorbidities
A 52-year-old overweight woman (BMI 29 kg/m2)with type 2 diabetes, hyperlipidemia, osteoarthritis, and glaucoma has recently hit a plateau with her weight loss. She lost 45 lb secondary to diet and exercise, but hasn’t been able to lose any more. She also struggles with constant hunger. Her medications include metformin 1,000 mg twice per day, atorvastatin 10 mg/d, and occasional acetaminophen/oxycodone for knee pain until she undergoes a left knee replacement. Laboratory values are normal except for a hemoglobin A1c of 7.2%.
The patient is afraid of needles and cannot tolerate stimulants due to anxiety. Which medication is an appropriate next step for this patient?
What are good choices for this patient?
Lorcaserin is a good choice for this patient who is overweight and has several weight-related comorbidities. She has worked hard to lose a significant number of pounds and is now at high risk of regaining them. That’s because her appetite has increased with her new exercise regimen, but her energy expenditure has decreased secondary to metabolic adaptation.
Narrowing the field. Naltrexone SR/bupropion SR cannot be used because of her opioid use. Phentermine/topiramate ER is contraindicated for patients with glaucoma, and liraglutide 3 mg is not appropriate given the patient’s fear of needles.
She could try orlistat, especially if she struggles with constipation, but the gastrointestinal adverse effects are difficult for many patients to tolerate. While not an antiobesity medication, a sodium-glucose co-transporter 2 (SGLT2) inhibitor could be prescribed for her diabetes and also may promote weight loss.43
An appealing choice. The glucose-lowering effect of lorcaserin could provide an added benefit for the patient. The BLOOMDM (Behavioral modification and lorcaserin for overweight and obesity management in diabetes mellitus) study reported a mean reduction in hemoglobin A1c of 0.9% in the treatment group compared with a 0.4% reduction in the placebo group,30 and the effect of lorcaserin on A1c appeared to be independent of weight loss.
Mechanism of action: Cause for concern? Although lorcaserin selectively binds to serotonin 5-HT2C receptors, the theoretical risk of cardiac valvulopathy was evaluated in phase III studies, as fenfluramine, a 5-HT2B-receptor agonist, was withdrawn from the US market in 1997 for this reason.44 Both the BLOOM (Behavioral modification and lorcaserin for overweight and obesity management) and BLOSSOM (Behavioral modification and lorcaserin second study for obesity management) studies found that lorcaserin did not increase the incidence of FDA-defined cardiac valvulopathy.28,29
Formulations/adverse effects. Lorcaserin is available in 2 formulations: 10-mg tablets, which are taken twice daily, or 20-mg XR tablets, which are taken once daily. Both are generally well tolerated.27,45 The most common adverse event reported in phase III trials was headache.28,30,43 Discontinue lorcaserin if the patient does not lose 5% of her initial weight after 12 weeks, as weight loss at this stage is a good predictor of longer-term success.46
Some patients don’t respond. Interestingly, a subset of patients do not respond to lorcaserin. The most likely explanation for different responses to the medication is that there are many causes of obesity, only some of which respond to 5-HT2C agonism. Currently, we do not perform pharmacogenomics testing before prescribing lorcaserin, but perhaps an inexpensive test to identify responders will be available in the future.
CASE 3 A preoccupation with food
A 38-year-old woman with obesity (BMI 42 kg/m2),obstructive sleep apnea, gastroesophageal reflux disease, and depression is eager to get better control over her weight. Her medications include lansoprazole 30 mg/d and a multivitamin. She reports constantly thinking about food and not being able to control her impulses to buy large quantities of unhealthy snacks. She is so preoccupied by thoughts of food that she has difficulty concentrating at work.
The patient smokes a quarter of a pack of cigarettes daily, but she is ready to quit. She views bariatric surgery as a “last resort” and has no anxiety, pain, or history of seizures. Which medication is appropriate for this patient?
Discuss all options
This patient with class III obesity (BMI ≥40 kg/m2) is eligible for bariatric surgery; however, she is not interested in pursuing it at this time. It is important to discuss all of her options before deciding on a treatment plan. For patients like this, who would benefit from more than modest weight loss, consider a multidisciplinary approach including lifestyle modifications, pharmacotherapy, devices (eg, an intragastric balloon), and/or surgery. You would need to make clear to the patient that she may still be eligible for insurance coverage for surgery if she changes her mind after pursuing other treatments as long as her BMI remains ≥35 kg/m2 with obesity-related comorbidities.
Naltrexone SR/bupropion SR is a good choice for this patient because she describes debilitating cravings and addictive behavior surrounding food. Patients taking naltrexone SR/bupropion SR in the Contrave Obesity Research (COR)-I and COR-II phase III trials experienced a reduced frequency of food cravings, reduced difficulty in resisting food cravings, and an increased ability to control eating compared with those assigned to placebo.32,33
Added benefits. Bupropion also could help this patient quit smoking and improve her mood, as it is FDA-approved for smoking cessation and depression. She denies anxiety and seizures, so bupropion is not contraindicated. Even if a patient denies a history of seizure, ask about any conditions that predispose to seizures, such as anorexia nervosa or bulimia or the abrupt discontinuation of alcohol, benzodiazepines, barbiturates, or antiepileptic drugs.
Opioid use. Although the patient denies pain, ask about potential opioid use, as naltrexone is an opioid receptor antagonist. Patients should be informed that opioids may be ineffective if they are required unexpectedly (eg, for trauma) and that naltrexone SR/bupropion SR should be withheld for any planned surgical procedure potentially requiring opioid use.
Other options. While naltrexone SR/bupropion SR is the most appropriate choice for this patient because it addresses her problematic eating behaviors while potentially improving mood and assisting with smoking cessation, phentermine/topiramate ER, lorcaserin, and liraglutide 3 mg also could be used and certainly should be tried if naltrexone SR/bupropion SR does not produce the desired weight loss.
Adverse effects. Titrate naltrexone SR/bupropion SR slowly to the treatment dose to minimize risks and adverse events.31 The most common adverse effects reported in phase III trials were nausea, constipation, and headache.34,35,45,46 Discontinue naltrexone SR/bupropion SR if the patient does not achieve 5% weight loss at 16 weeks (after 12 weeks at the maintenance dose).31
CASE 4 Regaining weight after gastric bypass
A 65-year-old woman with obesity (BMI 39 kg/m2)who underwent Roux-en-Y gastric bypass surgery and who has type 2 diabetes, congestive heart failure, coronary artery disease, hypertension, and hyperlipidemia, remains concerned about her weight. She lost 100 lb following surgery and maintained her weight for 3 years, but then regained 30 lb. She comes in for an office visit because she is concerned about her increasing blood sugar and wants to prevent further weight gain. Her medications include metformin 1,000 mg twice per day, lisinopril 5 mg/d, carvedilol 12.5 mg twice per day, simvastatin 20 mg/d, and aspirin 81 mg/d. Laboratory test results are normal except for a hemoglobin A1c of 8%. She denies pancreatitis and a personal or family history of thyroid cancer.
Which medication is an appropriate next step for this patient?
Pharmacotherapy is an option
Pharmacotherapy is a great option for this patient, who is regaining weight following bariatric surgery. Phentermine/topiramate ER is the only medication that would be contraindicated because of her heart disease. Lorcaserin and naltrexone SR/bupropion SR could be considered, but liraglutide 3 mg is the most appropriate option, given her need for further glucose control.
Furthermore, the recent LEADER (Liraglutide effect and action in diabetes: evaluation of CV outcome results) trial reported a significant mortality benefit with liraglutide 1.8 mg/d among patients with type 2 diabetes and high CV risk.47 The study found that liraglutide was superior to placebo in reducing CV events.
Contraindications. Ask patients about a history of pancreatitis before starting liraglutide 3 mg, given the possible increased risk. In addition, liraglutide is contraindicated in patients with a personal or family history of medullary thyroid carcinoma or in patients with multiple endocrine neoplasia syndrome type 2. Thyroid C-cell tumors have been found in rodents given supratherapeutic doses of liraglutide48; however, there is no evidence of liraglutide causing C-cell tumors in humans.
For patients taking a medication that can cause hypoglycemia, such as insulin or a sulfonylurea, monitor blood sugar and consider reducing the dose of that medication when starting liraglutide.
Administration and titration. Liraglutide is injected subcutaneously once daily. The dose is titrated up weekly to reduce gastrointestinal symptoms.36 The most common adverse effects reported in phase III trials were nausea, diarrhea, and constipation.37–39Discontinue liraglutide 3 mg if the patient does not lose at least 4% of baseline body weight after 16 weeks.49

Modest weight loss of 5% to 10% among patients who are overweight or obese can result in a clinically relevant reduction in cardiovascular (CV) disease risk.1 This amount of weight loss can increase insulin sensitivity in adipose tissue, liver, and muscle, and have a positive impact on blood sugar, blood pressure, triglycerides, and high-density lipoprotein cholesterol.1,2
All patients who are obese or overweight with increased CV risk should be counseled on diet, exercise, and other behavioral interventions.3 Weight loss secondary to lifestyle modification alone, however, leads to adaptive physiologic responses, which increase appetite and reduce energy expenditure.4–6
Pharmacotherapy can counteract this metabolic adaptation and lead to sustained weight loss. Antiobesity medication can be considered if a patient has a body mass index (BMI) ≥30 kg/m2 or ≥27 kg/m2 with obesity-related comorbidities such as hypertension, type 2 diabetes, dyslipidemia, or obstructive sleep apnea.3,7
For patients with a body mass index (BMI) ≥30 kg/m2 or BMI ≥27 kg/m2 with weight-related comorbidities:
- Consider antiobesity pharmacotherapy when diet, exercise, and behavior modification do not produce sufficient weight loss. A
- Continue an antiobesity medication if it is deemed effective and well tolerated.A
A Good-quality patient-oriented evidence
B Inconsistent or limited-quality patient-oriented evidence
C Consensus, usual practice, opinion, disease-oriented evidence, case series
Until recently, there were few pharmacologic options approved by the US Food and Drug Administration (FDA) for the management of obesity. The mainstays of treatment were phentermine (Adipex-P, Ionamin, Suprenza) and orlistat (Alli, Xenical). Since 2012, however, 4 agents have been approved as adjuncts to a reduced-calorie diet and increased physical activity for long-term weight management.8,9 Phentermine/topiramate extended-release (ER) (Qsymia) and lorcaserin (Belviq) were approved in 2012,10,11 and naltrexone sustained release (SR)/bupropion SR (Contrave) and liraglutide 3 mg (Saxenda) were approved in 201412,13 (TABLE9,14–39). These medications have the potential to not only limit weight gain but also promote weight loss and, thus, improve blood pressure, cholesterol, glucose, and insulin.40
Despite the growing obesity epidemic and the availability of several additional medications for chronic weight management, use of antiobesity pharmacotherapy has been limited. Barriers to use include inadequate training of health care professionals, poor insurance coverage for new agents, and low reimbursement for office visits to address weight.41
In addition, the number of obesity medicine specialists, while increasing, is still not sufficient. Therefore, it is imperative for other health care professionals—including ObGyns—to be aware of the treatment options available to patients who are overweight or obese and to be adept at using them.
In this review, we present 4 cases that depict patients who could benefit from the addition of antiobesity pharmacotherapy to a comprehen‑sive treatment plan that includes diet, physical activity, and behavioral modification.
CASE 1 Young obese woman is unable to lose weight
A 27-year-old woman with obesity (BMI 33 kg/m2),hyperlipidemia, and migraine headaches, pre‑sents for weight management. Despite a calorie-reduced diet and 200 minutes per week of exercise for the past 6 months, she has been unable to lose weight. The only medications she is taking are oral contraceptive pills and sumatriptan, as needed. She suffers from migraines 3 times a month and has no anxiety. Laboratory test results are normal with the exception of an elevated low-density lipoprotein (LDL) level.
Which medication is an appropriate next step for this patient?
Ask 2 important questions
When considering an antiobesity agent for any patient, there are 2 important questions to ask:
- Are there contraindications, drug-drug interactions, or undesirable adverse effects associated with this medication that could be problematic for the patient?
- Can this medication improve other symptoms or conditions the patient has?
In addition, see “Before prescribing antiobesity medication . . .” below.
Have a frank discussion with the patient and be sure to cover the following points:
The rationale for pharmacologic treatment is to counteract adaptive physiologic responses, which increase appetite and reduce energy expenditure, in response to diet-induced weight loss.
Antiobesity medication is only one component of a comprehensive treatment plan, which also includes diet, physical activity, and behavior modification.
Antiobesity agents are intended for long-term use, as obesity is a chronic disease. If/when you stop the medication, there may be some weight regain, similar to an increase in blood pressure after discontinuing an antihypertensive agent.
Because antiobesity medications improve many parameters including glucose/hemoglobin A1c, lipids, blood pressure, and waist circumference, it is possible that the addition of one antiobesity medication can reduce, or even eliminate, the need for several other medications.
Remember that many patients who present for obesity management have experienced weight bias. It is important to not be judgmental, but rather explain why obesity is a chronic disease. If patients understand the physiology of their condition, they will understand that their limited success with weight loss in the past is not just a matter of willpower. Lifestyle change and weight loss are extremely difficult, so it is important to provide encouragement and support for ongoing behavioral modification.
Phentermine/topiramate ER
Phentermine/topiramate ER is a good first choice for this young patient with class I (BMI 30–34.9 kg/m2) obesity and migraines, as she can likely tolerate a stimulant and her migraines might improve with topiramate. Before starting the medication, ask about insomnia and nephrolithiasis in addition to anxiety and other contraindications (ie, glaucoma, hyperthyroidism, recent monoamine oxidase inhibitor use, or a known hypersensitivity or idiosyncrasy to sympathomimetic amines).23 The most common adverse events reported in phase III trials were dry mouth, paresthesia, and constipation.24–26
Not for pregnant women. Women of childbearing age must have a negative pregnancy test before starting phentermine/topiramate ER and every month while taking the medication. The FDA requires a Risk Evaluation and Mitigation Strategy (REMS) to inform prescribers and patients about the increased risk of congenital malformation, specifically orofacial clefts, in infants exposed to topiramate during the first trimester of pregnancy.42 REMS focuses on the importance of pregnancy prevention, the consistent use of birth control, and the need to discontinue phentermine/topiramate ER immediately if pregnancy occurs.
Flexible dosing. Phentermine/topiramate ER is available in 4 dosages: phentermine 3.75 mg/topiramate 23 mg ER; phentermine 7.5 mg/topiramate 46 mg ER; phentermine 11.25 mg/topiramate 69 mg ER; and phentermine 15 mg/topiramate 92 mg ER. Gradual dose escalation minimizes risks and adverse events.23
Monitor patients frequently to evaluate for adverse effects and ensure adherence to diet, exercise, and lifestyle modifications. If weight loss is slower or less robust than expected, check for dietary indiscretion, as medications have limited efficacy without appropriate behavioral changes.
Discontinue phentermine/topiramate ER if the patient does not achieve 5% weight loss after 12 weeks on the maximum dose, as it is unlikely that she will achieve and sustain clinically meaningful weight loss with continued treatment.23 In this case, consider another agent with a different mechanism of action. Any of the other antiobesity medications could be appropriate for this patient.
CASE 2 Overweight woman with comorbidities
A 52-year-old overweight woman (BMI 29 kg/m2)with type 2 diabetes, hyperlipidemia, osteoarthritis, and glaucoma has recently hit a plateau with her weight loss. She lost 45 lb secondary to diet and exercise, but hasn’t been able to lose any more. She also struggles with constant hunger. Her medications include metformin 1,000 mg twice per day, atorvastatin 10 mg/d, and occasional acetaminophen/oxycodone for knee pain until she undergoes a left knee replacement. Laboratory values are normal except for a hemoglobin A1c of 7.2%.
The patient is afraid of needles and cannot tolerate stimulants due to anxiety. Which medication is an appropriate next step for this patient?
What are good choices for this patient?
Lorcaserin is a good choice for this patient who is overweight and has several weight-related comorbidities. She has worked hard to lose a significant number of pounds and is now at high risk of regaining them. That’s because her appetite has increased with her new exercise regimen, but her energy expenditure has decreased secondary to metabolic adaptation.
Narrowing the field. Naltrexone SR/bupropion SR cannot be used because of her opioid use. Phentermine/topiramate ER is contraindicated for patients with glaucoma, and liraglutide 3 mg is not appropriate given the patient’s fear of needles.
She could try orlistat, especially if she struggles with constipation, but the gastrointestinal adverse effects are difficult for many patients to tolerate. While not an antiobesity medication, a sodium-glucose co-transporter 2 (SGLT2) inhibitor could be prescribed for her diabetes and also may promote weight loss.43
An appealing choice. The glucose-lowering effect of lorcaserin could provide an added benefit for the patient. The BLOOMDM (Behavioral modification and lorcaserin for overweight and obesity management in diabetes mellitus) study reported a mean reduction in hemoglobin A1c of 0.9% in the treatment group compared with a 0.4% reduction in the placebo group,30 and the effect of lorcaserin on A1c appeared to be independent of weight loss.
Mechanism of action: Cause for concern? Although lorcaserin selectively binds to serotonin 5-HT2C receptors, the theoretical risk of cardiac valvulopathy was evaluated in phase III studies, as fenfluramine, a 5-HT2B-receptor agonist, was withdrawn from the US market in 1997 for this reason.44 Both the BLOOM (Behavioral modification and lorcaserin for overweight and obesity management) and BLOSSOM (Behavioral modification and lorcaserin second study for obesity management) studies found that lorcaserin did not increase the incidence of FDA-defined cardiac valvulopathy.28,29
Formulations/adverse effects. Lorcaserin is available in 2 formulations: 10-mg tablets, which are taken twice daily, or 20-mg XR tablets, which are taken once daily. Both are generally well tolerated.27,45 The most common adverse event reported in phase III trials was headache.28,30,43 Discontinue lorcaserin if the patient does not lose 5% of her initial weight after 12 weeks, as weight loss at this stage is a good predictor of longer-term success.46
Some patients don’t respond. Interestingly, a subset of patients do not respond to lorcaserin. The most likely explanation for different responses to the medication is that there are many causes of obesity, only some of which respond to 5-HT2C agonism. Currently, we do not perform pharmacogenomics testing before prescribing lorcaserin, but perhaps an inexpensive test to identify responders will be available in the future.
CASE 3 A preoccupation with food
A 38-year-old woman with obesity (BMI 42 kg/m2),obstructive sleep apnea, gastroesophageal reflux disease, and depression is eager to get better control over her weight. Her medications include lansoprazole 30 mg/d and a multivitamin. She reports constantly thinking about food and not being able to control her impulses to buy large quantities of unhealthy snacks. She is so preoccupied by thoughts of food that she has difficulty concentrating at work.
The patient smokes a quarter of a pack of cigarettes daily, but she is ready to quit. She views bariatric surgery as a “last resort” and has no anxiety, pain, or history of seizures. Which medication is appropriate for this patient?
Discuss all options
This patient with class III obesity (BMI ≥40 kg/m2) is eligible for bariatric surgery; however, she is not interested in pursuing it at this time. It is important to discuss all of her options before deciding on a treatment plan. For patients like this, who would benefit from more than modest weight loss, consider a multidisciplinary approach including lifestyle modifications, pharmacotherapy, devices (eg, an intragastric balloon), and/or surgery. You would need to make clear to the patient that she may still be eligible for insurance coverage for surgery if she changes her mind after pursuing other treatments as long as her BMI remains ≥35 kg/m2 with obesity-related comorbidities.
Naltrexone SR/bupropion SR is a good choice for this patient because she describes debilitating cravings and addictive behavior surrounding food. Patients taking naltrexone SR/bupropion SR in the Contrave Obesity Research (COR)-I and COR-II phase III trials experienced a reduced frequency of food cravings, reduced difficulty in resisting food cravings, and an increased ability to control eating compared with those assigned to placebo.32,33
Added benefits. Bupropion also could help this patient quit smoking and improve her mood, as it is FDA-approved for smoking cessation and depression. She denies anxiety and seizures, so bupropion is not contraindicated. Even if a patient denies a history of seizure, ask about any conditions that predispose to seizures, such as anorexia nervosa or bulimia or the abrupt discontinuation of alcohol, benzodiazepines, barbiturates, or antiepileptic drugs.
Opioid use. Although the patient denies pain, ask about potential opioid use, as naltrexone is an opioid receptor antagonist. Patients should be informed that opioids may be ineffective if they are required unexpectedly (eg, for trauma) and that naltrexone SR/bupropion SR should be withheld for any planned surgical procedure potentially requiring opioid use.
Other options. While naltrexone SR/bupropion SR is the most appropriate choice for this patient because it addresses her problematic eating behaviors while potentially improving mood and assisting with smoking cessation, phentermine/topiramate ER, lorcaserin, and liraglutide 3 mg also could be used and certainly should be tried if naltrexone SR/bupropion SR does not produce the desired weight loss.
Adverse effects. Titrate naltrexone SR/bupropion SR slowly to the treatment dose to minimize risks and adverse events.31 The most common adverse effects reported in phase III trials were nausea, constipation, and headache.34,35,45,46 Discontinue naltrexone SR/bupropion SR if the patient does not achieve 5% weight loss at 16 weeks (after 12 weeks at the maintenance dose).31
CASE 4 Regaining weight after gastric bypass
A 65-year-old woman with obesity (BMI 39 kg/m2)who underwent Roux-en-Y gastric bypass surgery and who has type 2 diabetes, congestive heart failure, coronary artery disease, hypertension, and hyperlipidemia, remains concerned about her weight. She lost 100 lb following surgery and maintained her weight for 3 years, but then regained 30 lb. She comes in for an office visit because she is concerned about her increasing blood sugar and wants to prevent further weight gain. Her medications include metformin 1,000 mg twice per day, lisinopril 5 mg/d, carvedilol 12.5 mg twice per day, simvastatin 20 mg/d, and aspirin 81 mg/d. Laboratory test results are normal except for a hemoglobin A1c of 8%. She denies pancreatitis and a personal or family history of thyroid cancer.
Which medication is an appropriate next step for this patient?
Pharmacotherapy is an option
Pharmacotherapy is a great option for this patient, who is regaining weight following bariatric surgery. Phentermine/topiramate ER is the only medication that would be contraindicated because of her heart disease.

Cost-effective wound healing described with fetal bovine collagen matrix
CHICAGO – A novel, commercially available fetal bovine collagen matrix provides “an ideal wound healing environment” for outpatient treatment of partial and full thickness wounds, ulcers, burns, and surgical wounds, Katarina R. Kesty, MD, declared at the annual meeting of the American College of Mohs Surgery.
“
She shared the clinical experience she and her colleagues have accrued with this product, which is called PriMatrix and is manufactured by Integra LifeSciences. She also explained how to successfully code and bill for its use.
“In-office application of this product is cost-effective when compared to similar products applied in the operating room by plastic surgeons and other specialists,” Dr. Kesty noted.
How cost-effective? She provided one example of a patient with a 12.6-cm2 defect on the scalp repaired with fetal bovine collagen matrix. Upon application of the appropriate billing codes, this repair was reimbursed by Medicare to the tune of $1,208. In contrast, another patient at Wake Forest had a 16.6-cm2 Mohs defect on the scalp repaired in the operating room by an oculoplastic surgeon who used split thickness skin grafts. For this procedure, Medicare was billed $30,805.11, and the medical center received $9,241.53 in reimbursement.
“An office repair using this fetal bovine collagen matrix is much more cost-effective,” she observed. “It also saves the patient from the risks of general anesthesia or conscious sedation.”
PriMatrix is a porous acellular collagen matrix derived from fetal bovine dermis. It contains type I and type III collagen, with the latter being particularly effective at attracting growth factors, blood, and angiogenic cytokines in support of dermal regeneration and revascularization. The product is available in solid sheets, mesh, and fenestrated forms in a variety of sizes. It needs to be rehydrated for 1 minute in room temperature saline. It can then be cut to the size of the wound and secured to the wound bed, periosteum, fascia, or cartilage with sutures or staples. The site is then covered with a thick layer of petrolatum and a tie-over bolster.
Dr. Kesty and her dermatology colleagues have applied the matrix to surgical defects ranging in size from 0.2 cm2 to 70 cm2, with an average area of 19 cm2. They have utilized the mesh format most often in order to allow drainage. They found the average healing time when the matrix was applied to exposed bone, periosteum, or perichondrium was 13.8 weeks, compared with 10.8 weeks for subcutaneous wounds.
With the use of the fetal bovine collagen matrix, wounds less than 10 cm2 in size healed in an average of 9.3 weeks, those from 10 cm2 to 25 cm2 in size healed in an average of 10.4 weeks, and wounds larger than 25 cm2 healed in an average of 15.7 weeks.
Coding and reimbursement
PriMatrix has been available for outpatient office use and reimbursement by Medicare since January 2017. Successful reimbursement requires completion of a preauthorization form, which is typically approved on the same day by Medicare and other payers. The proper CPT codes are 1527x, signifying a skin substitute graft less than 100 cm2 in size; Q4110 times the number of 1-cm2 units of PriMatrix utilized; and, when appropriate, ICD10 code Z85.828, for personal history of nonmelanoma skin cancer.
Dr. Kesty reported no financial conflicts of interest.

EXPERT ANALYSIS FROM THE ACMS ANNUAL MEETING
CMS targets Part B drug policy in 2019 regulatory updates
Doctors could see changes in how they are paid by the Centers for Medicare & Medicaid Services for the drugs they administer in their office, depending on the outcome of two recent regulatory actions proposed by the agency.
The more immediate action could see an alteration to payment rates for newly launched drugs. The more long-term action could be the relaunch of the Competitive Acquisition Program, although there is much more uncertainty surrounding that change.
CMS is seeking to lower the Part B add-on payment for drugs that are new to market and do not yet have an average sales price (ASP) established. The proposal calls for these drugs to be reimbursed at the wholesale acquisition cost (WAC) plus 3%, rather than the current rate of WAC plus 6%. The change is part of the proposed physician fee schedule for 2019.
The add-on payment has no statutory definition as to what it is intended to cover, but CMS noted in the proposed rule that it “is widely believed to include services associated with drug acquisition that are not separately paid for, such as handling and storage, as well as additional mark-ups in drug distribution channels.”
Agency officials said that the add-on payment has raised concerns in recent years “because more revenue can be generated from percentage-based add-on payments for expensive drugs, and an opportunity to generate more revenue may create an incentive for the use of more expensive drugs.”
CMS also noted that once an ASP has been established – generally after a drug has been available for several months – the price for that drug is generally lower than the WAC price and, citing a 2014 HHS Office of Inspector General report, noted that “WACs often do not reflect the actual market price for drugs.”
The move to lower payments to WAC plus 3% for new drugs is consistent with a recent recommendation from the Medicare Payment Advisory Commission (MedPAC).
CMS added that the reduction would reduce beneficiary out-of-pocket costs, since copayments are a percentage of the total cost of the drug, including the add-on payment amount.
“The proposed approach would help Medicare beneficiaries afford to pay for new drugs by reducing out-of-pocket expenses and would help counteract the effects of increasing launch prices for newly approved drugs and biologicals,” CMS said in the proposed regulation.
But the American College of Rheumatology raised concerns about the proposal. Specifically, ACR is concerned that plans to cut add-on payments for new drugs “could slow market uptake of biosimilars and thwart the Administration’s efforts to reduce drug prices,” the group said in a statement.
The Community Oncology Alliance (COA) also took issue with the proposal. “This is a payment cut from the current rate of Wholesale Acquisition Cost (WAC) plus 6%, or what is really plus 4.3% when factoring in the sequester,” the COA said in a statement. “COA believes that this payment cut for new cancer therapies will result in drug manufacturers actually increasing WAC list prices so that their new products will not be at a competitive disadvantage to existing products, which are reimbursed at average sales price (ASP) plus 6%.”
The second proposal, which could take longer to materialize, revolves around the potential relaunch of the failed competitive acquisition program (CAP) for Part B drugs. CMS is currently requesting information, with questions on what a revamped program could look like if the agency were to move forward with it. The request for information is part of the proposed rule updating the Outpatient Prospective Payment System for 2019.
Under the original CAP, physicians who participated in the program would order drugs from an approved vendor, who would then bill Medicare and collect cost-sharing payments from the beneficiary. The original program was in operation for 18 months, ending on Dec. 31, 2008, after it had little participation and faced other concerns.
More recently, MedPAC recommended a revised version of the program, which they dubbed the Part B Drug Value Program (DVP). Under this construct, private vendors would acquire drugs at lower prices using various negotiation tools, and physicians would be encouraged to make more value-based use decisions based on opportunities for shared savings though their Medicare billing for the use of Part B drugs.
CMS is asking for feedback on a wide range of questions on how the revamped CAP program should be designed, including program design, which suppliers and drugs to include, how to incentivize participation, how to structure outcomes-based arrangements, and whether indication-based pricing should be used.

Five common pitfalls of retailing skin care
Others believe that providing patients with the correct skin care product recommendations for their skin’s needs is a crucial step to improving outcomes and educating patients.
There is a wide range of challenges related to skin care retail that many physicians face. I will be running a course on Skin Care Retail at the American Society for Dermatologic Surgery meeting in October in Scottsdale, Ariz., if you want to learn more or share your opinions. I have surveyed plastic surgeons and dermatologists via LinkedIn about what they believe are some of the biggest pitfalls to retailing skin care. Here, I will share some of their insights and suggestions for overcoming these obstacles.
1. Patients are more knowledgeable about skin care than ever before
Facing an increasing number of over-the-counter skin care products available, as well as buzzwords like “organic ingredients” and “vegan,” patients are now bombarded with information from a variety of different sources. Because of this, patients come to the doctor with preconceived ideas that can affect compliance if their specific needs and beliefs are not properly addressed.
For New York plastic surgeon Sonita M. Sadio, MD, this is one of the reasons why she chooses not to sell skin care in her office.
“My practice is highly consultative, and ongoing skin care recommendations are a significant part of what I do to optimize patient outcomes,” Dr. Sadio said. “Patients are well-educated about skin care today. They know their ingredients and insist on clean formulations, free of certain ingredients, such as ‘cruelty-free’ and ‘vegan.’ Others feel deprived if they are not using an expensive product in elegant packaging. Still, others insist on drugstore favorites or ‘eco’ offerings and have their own sense of what that means. My job is to optimize the clinical outcome while also meeting these patients needs to ensure compliance.”
Not all doctors have the time, knowledge or desire to personally design each patient’s skin care regimen. Many delegate this to the staff. However, it is impossible to ensure that your staff matches patients to the proper products unless they have had extensive training on both skin care products and how to match them to the patient’s skin issues.
2. Patients are wary when the doctors sells only one product brand
Many studies have shown that, although consumers desire a choice when making purchases, they get overwhelmed if they are presented with too many options. One study showed that it is optimal to carry at least 3 brands of products. For this reason, limiting the skin care you sell to one brand or doing your own private label is not optimal.
New York dermatologist Rebecca Tamez, MD, pointed out the same problem when selling practice-specific skin care. “At my previous job, we sold skin care products directly to patients. I had no issues selling products that were readily available in drugstores or online (such as Vanicream and EltaMD). We usually sold these around the same cost as the drugstore or Amazon. However, it was harder to sell the practice-specific skin care line. I feel patients were more wary of these products.”
3. Doctors do not want to feel like salespeople
If you have read my Dermatology News columns in the past, you may know that I think it is unethical for dermatologists to not offer specific skin care advice to their patients. If patients do not get ethical and scientific recommendations from us, they will follow the advice of a friend or salesperson or purchase based on often inflated marketing claims.
Dermatologists often tell me: “I am not a cosmetic dermatologist so I do not sell skin care.” I feel strongly that general dermatologists should be giving specific written skin care recommendations for their patients too. Acne, rosacea, melasma, eczema, psoriasis, keratosis pilaris, and many other conditions will improve faster with an efficacious skin care regimen, assuming the patient is compliant with the instructions. Retailing skin care improves compliance by eliminating a few barriers to beginning the skin care regimen. I believe that the mindset of dermatologists needs to change: It is not about selling products to patients, it is about educating them on what to use and offering the products out of convenience and the desire to improve compliance.
Meadowbrook, Pa., dermatologist Michael A. Tomeo, MD, explained an obstacle faced by many dermatologists:
“I suspect, like many of my colleagues,” said Dr. Tomeo, “that I am held back in terms of salesmanship, having been trained in the traditional way. Physicians of my generation were taught to be ethical and professional and to focus on academic and clinical excellence, and salesmanship and advertising one’s services were frowned upon. It takes time to reset one’s former proclivities. Cosmeceuticals and nutraceuticals are revolutionizing the skin care world, and as experts in all things skin, we need to be well informed and offer our patients safe, effective, and cutting-edge treatments.”
4. Providers are concerned about product costs and time constraints
Providing excellent patient care and improving outcomes is at the forefront of our business, but financial concerns and time constraints prevent some doctors from offering skin care to their patients.
Rochester Hills, Mich., plastic surgeon Richard Hainer, MD, has found that “skin care is often too complex with too many products and is not very profitable.” For those reasons, Dr. Hainer has chosen not to retail skin care in his practice.
Nampa, Idaho, dermatologist Ryan S. Owsley, MD, explained that “the required minimum purchases by some of the product lines can leave the practice with expired product if it is not selling a particular line well. Cost can also be an issue for some patients in the area we are located.”
As a burn survivor and burn surgeon, Mark McDonough, MD, from Orlando “has a long history with skin care and rejuvenation. I did have a private label skin care line, including a moisturizer, a hydroquinone product, a retinol cream, and a sunscreen,” Dr. McDonough said. “However, and regrettably, I have not kept up with marketing and promotion, with most of my energy invested in trauma and disease survivors through a book, a blog, and my platform through my website.”
Doing your own product line is costly and spending the time and resources to promote it is not always possible. Buying the minimum order of products is often expensive, and you will not be able to sell them without a proven methodology in place. New products enter the market frequently, and it is expensive to always carry the latest technologies because new minimum orders must be met with each new brand that you add.
5. Selling skin care requires ongoing education
Properly recommending and retailing skin care involves physician, staff, and patient education. Unfortunately, most practices rely on training from the cosmeceutical sales reps who obviously have a brand bias. There is minimal unbiased “brand agnostic” skin care training for dermatologists and their staff. In fact, the AAD meeting has only a few skin care lectures in the program. Plastic surgeon Gaurav Bharti, MD, of Charlotte, N.C., explained that “motivating staff to help with retail skin care can be challenging. The first step is to get the staff familiar with the products with open discussions with the representatives. The next step has been to have the staff actually use the products and believe in them. Once they believe in the product, we have used an incentivization model that’s simple, transparent, and predictable.”
We are all too busy to spend adequate time with our patients, so it is critical that our staff be able to properly recommended skin care for us. We have to ensure that our staff is taking an ethical and scientific approach to skin care retail rather than a financial one. Rigorous staff training on how to match skin care products to skin type is the key to improving outcomes with skin care recommendations.
In a similar sense, Cincinnati plastic surgeon Richard Williams, MD, commented that “aestheticians often succumb to the desires of our patients to carry too many products in inventory, for which they do not have enough knowledge of the product’s benefits. This can be a very frustrating challenge.”
Conclusion
Although there are many obstacles to retailing skin care in your medical practice, the benefits that it provides to both your patients (improved outcomes) and your practice (increased profitability) far outweigh the challenges. I solved these pitfalls in my own practice by developing a standardized staff training program and skin care diagnostic software that is now used by over 100 medical practices. If you want to start retaining skin care, my advice is develop a training plan and a methodology for the recommendation and patient education process before you spend a lot of money on the required minimum product order.

There is a wide range of challenges related to skin care retail that many physicians face. I will be running a course on Skin Care Retail at the American Society for Dermatologic Surgery meeting in October in Scottsdale, Ariz., if you want to learn more or share your opinions. I have surveyed plastic surgeons and dermatologists via LinkedIn about what they believe are some of the biggest pitfalls to retailing skin care. Here, I will share some of their insights and suggestions for overcoming these obstacles.
1. Patients are more knowledgeable about skin care than ever before
Facing an increasing number of over-the-counter skin care products available, as well as buzzwords like “organic ingredients” and “vegan,” patients are now bombarded with information from a variety of different sources. Because of this, patients come to the doctor with preconceived ideas that can affect compliance if their specific needs and beliefs are not properly addressed.
For New York plastic surgeon Sonita M. Sadio, MD, this is one of the reasons why she chooses not to sell skin care in her office.
“My practice is highly consultative, and ongoing skin care recommendations are a significant part of what I do to optimize patient outcomes,” Dr. Sadio said. “Patients are well-educated about skin care today. They know their ingredients and insist on clean formulations, free of certain ingredients, such as ‘cruelty-free’ and ‘vegan.’ Others feel deprived if they are not using an expensive product in elegant packaging. Still, others insist on drugstore favorites or ‘eco’ offerings and have their own sense of what that means. My job is to optimize the clinical outcome while also meeting these patients needs to ensure compliance.”
Not all doctors have the time, knowledge or desire to personally design each patient’s skin care regimen. Many delegate this to the staff. However, it is impossible to ensure that your staff matches patients to the proper products unless they have had extensive training on both skin care products and how to match them to the patient’s skin issues.

MOC: ACOG’s role in developing a solution to the heated controversy
The American Board of Medical Specialties (ABMS) has decided to trade the phrase “maintenance of certification” (MOC) for “continuing board certification,” a seemingly minor change that has an important backstory. This is the story of how the physician community flexed its collective muscle and how the American College of Obstetricians and Gynecologists (ACOG) helped broker an important détente and pathway in a highly contentious issue.
Founded in 1933 as a nonprofit organization dedicated to maintaining high uniform standards among physicians, the ABMS and many of its specialty boards have found themselves, for more than a decade, under heavy fire from physicians (especially family physicians, internists, and surgeons), their 24 subspecialties, and the state medical societies representing them.
The ObGyn experience with the American Board of Obstetrics and Gynecology (ABOG), however, is better for a number of reasons. Historically, ABOG and ACOG have worked closely together, which is an anomaly among boards as many boards have an arms-length or even an antagonistic relationship with their specialty society.
The discussion below outlines physician concerns with the ABMS and related boards and describes efforts to address and rebuild the continuing board certification process.
Direct and indirect costs
Physicians are very concerned with the costs involved in MOC. Measurable costs include testing fees, while indirect costs include time, stress, travel to test centers, and threats to livelihood for failing a high-stakes examination. Physicians want the high-stakes exam eliminated.
Relevance to practice
Physicians often feel that the MOC has little relevance to their practice, which fuels a sense of resentment toward boards that they believe are dominated by physicians who no longer practice. Subspecialists feel farther away from general practice and the base exams. Generalists feel that the exams miss the points of their daily practice.
Lack of data to show improved quality of care
Physicians want to know that the MOC is worth their time, effort, and money because it improves patient care. To date, however, empirical or clinical data on patient outcomes are absent or ambiguous; most studies lack high-level data or do not investigate the MOC requirements. Physicians want to know what the best MOC practices are, what improves care, and that practices that make no difference will be discarded. In addition, they want timely knowledge alerts when evidence changes.
Relationship to licensing, employment, privileging, credentialing, and reimbursement
Hospitals, insurers, and states increasingly—and inappropriately—use board certification as the primary (sometimes only) default measure of a physician’s fitness for patient care. Physicians without board certification often are denied hospital privileges, inclusion in insurance panels, and even medical licenses. This changes certification from a voluntary physician self-improvement exercise into a can’t-earn-a-living-without-it cudgel.
Variation
Boards vary significantly in their MOC requirements and costs. The importance of an equal standard across all boards is a clear theme among physician concerns.
Role and authority of the ABMS and related boards
Many physicians are frustrated with the perceived autocratic nature of their boards—boards that lack transparency, do not solicit or allow input from practicing physicians, and are unresponsive to physician concerns.
According to Susan Ramin, MD, ABOG Associate Executive Director, ABOG is leading in a number of these areas, including:
- rapidly disseminating clinical information on emerging topics, such as Zika virus infection and opioid misuse
- offering physician choice of testing categories
- exempting high scorers from the secured written exam, which saved physicians a total of $881,000 in exam fees
- crediting physicians for what they already are doing, including serving on maternal mortality review committees, participating in registries, and participating in the Alliance for Innovation on Maternal Health (AIM)
- providing Lifelong Learning and Self-Assessment (LLSA) articles that, according to 90% of diplomates surveyed, are beneficial to their clinical practice (FIGURE).1,2
Our colleague physicians are not so lucky. In a 2015 New England Journal of Medicine Perspective, one physician called out the American Board of Internal Medicine as “a private, self-appointed certifying organization,” a not-for-profit organization that has “grown into a $55-million-per-year business.”3 He concluded that “many physicians are waking up to the fact that our profession is increasingly controlled by people not directly involved in patient care who have lost contact with the realities of day-to-day clinical practice.”3
State and society responses to MOC requirements
Frustration with an inability to resolve these concerns has grown steadily, bubbling over into state governments. The American Medical Association developed “model state legislation intended to prohibit hospitals, health care insurers, and state boards of medicine and osteopathic medicine from requiring participation in MOC processes as a condition of credentialing, privileging, insurance panel participation, licensure, or licensure renewal.”4
Some states are proposing or have enacted legislation that prohibits the use of MOC as a criterion for licensure, privileging, employment, reimbursement, and/or insurance panel participation. Eight states (Arizona, Georgia, Kentucky, Maryland, Maine, Missouri, Oklahoma, Tennessee) have enacted laws to prohibit the use of MOC for initial and renewal licensure decisions. Many states are actively considering MOC-related legislation, including Alaska, Florida, Iowa, Indiana, Maryland, Massachusetts, Michigan, Missouri, New Hampshire, New York, Ohio, Oklahoma, Rhode Island, South Carolina, Tennessee, Utah, Washington, and Wisconsin.
Legislation is not the only outlet for physician frustration. Some medical specialty societies are considering dropping board certification as a membership requirement; physicians are exploring developing alternative boards; and some physicians are defying the board certification requirement altogether, with thousands signing anti-MOC petitions.
ACOG asserts importance of maintaining self-regulation
While other specialties are actively advocating state legislation, ACOG and ABOG have worked together to oppose state legislation, believing that physician self-regulation is paramount. In fact, in 2017, ACOG and ABOG issued a joint statement urging state lawmakers to “not interfere with our decades of successful self-regulation and to realize that each medical society has its own experience with its MOC program.”5
Negotiations lead to new initiative
This brings us to an interesting situation. ACOG’s Executive Vice President and CEO Hal Lawrence III, MD, was tapped (in his position as Chair of the Specialty Society CEO Consortium) to represent physician specialties in negotiations and discussions with the boards, which were represented by Lois Nora, MD, JD, President and CEO of the ABMS, and state medical societies, represented by Donald Palmisano Jr, JD, Executive Director and CEO of the Medical Association of Georgia. Many state medical societies, boards, and physician specialty organizations participated in these meetings.
Throughout months of debate, Dr. Lawrence urged his colleagues to stay at the table and do the hard work of reaching an agreement, rather than ask politicians to solve medicine’s problems. This approach was leveraged by the serious efforts and threats of state legislation, which brought the boards to the table. In August 2017, 41 state medical societies and 33 national medical specialty societies wrote to Dr. Nora expressing their concerns that “professional self-regulation is under attack. Concerns regarding the usefulness of the high-stakes exam, the exorbitant costs of the MOC process, and the lack of transparent communication from the certifying boards have led to damaging the MOC brand, and creating state-based attacks on the MOC process.”6
In December 2017, Dr. Lawrence and Mr. Palmisano led a meeting of principals from the national medical specialty societies and state medical societies with leaders of ABMS and 8 specialty boards, including ABOG, an opportunity to secure meaningful change. Dr. Lawrence began by stressing that the interests of physicians and patients would be best served by all parties coming together and collaborating on a meaningful solution, to repair trust and preserve physician self-regulation.
Dr. Ramin presented ABOG’s approach to continuous certification, lifelong learning, and self-assessment. The American Board of Urology and the American Board of Psychiatry and Neurology indicated that they were basing important changes in their MOC process on ABOG’s work, including using 5 modules (1 general and 4 specific to the physician’s practice) and multiple open-book mini-exams based on selected journal articles as an alternative to the 10-year MOC exam.
The Vision Initiative. At that meeting and others, the ABMS and other boards heard physicians’ candid and sometimes blunt concerns. Dr. Nora spoke to the recently announced Continuing Board Certification: Vision for the Future program, also known as the “Vision Initiative,” a process designed to fundamentally rebuild the continuing certification process with input and guidance from practicing physicians. Physician response seemed uniform: Seeing is believing.
Importantly, all participants at the December meeting agreed to work together to rebuild trust and ensure professionalism and professional self-regulation, reflected in this Statement of Shared Purpose:
ABMS certifying boards and national medical specialty societies will collaborate to resolve differences in the process of ongoing certification and to fulfill the principles of professional self-regulation, achieving appropriate standardization, and assuring that ongoing certification is relevant to the practices of physicians without undue burden. Furthermore, the boards and societies, and their organizations (ABMS and CMSS [Council of Medical Specialty Societies]), will undertake necessary changes in a timely manner, and will commit to ongoing communication with state medical associations to solicit their input.4
Two ObGyns participating in the Vision Initiative are Haywood Brown, MD, ACOG’s Immediate Past President, and George Wendel, MD, ABOG’s Executive Director. The Vision Initiative is composed of 3 parts. Part 1, Organization, is complete. The committee is currently working on part 2, Envisioning the Future, an information-gathering component that includes physician surveys, hearings, open solicited input, and identifying new and better approaches. After the final report is delivered to the ABMS in February 2019, part 3, Implementation, will begin.
The Vision Initiative offers physicians an important opportunity to help shape the future of continuing education and certification. ObGyns and other physicians should consider reviewing and commenting on the draft report, due in November, during the public comment period.

The American Board of Medical Specialties (ABMS) has decided to trade the phrase “maintenance of certification” (MOC) for “continuing board certification,” a seemingly minor change that has an important backstory. This is the story of how the physician community flexed its collective muscle and how the American College of Obstetricians and Gynecologists (ACOG) helped broker an important détente and pathway in a highly contentious issue.
Founded in 1933 as a nonprofit organization dedicated to maintaining high uniform standards among physicians, the ABMS and many of its specialty boards have found themselves, for more than a decade, under heavy fire from physicians (especially family physicians, internists, and surgeons), their 24 subspecialties, and the state medical societies representing them.
The ObGyn experience with the American Board of Obstetrics and Gynecology (ABOG), however, is better for a number of reasons. Historically, ABOG and ACOG have worked closely together, which is an anomaly among boards as many boards have an arms-length or even an antagonistic relationship with their specialty society.
The discussion below outlines physician concerns with the ABMS and related boards and describes efforts to address and rebuild the continuing board certification process.
Direct and indirect costs
Physicians are very concerned with the costs involved in MOC. Measurable costs include testing fees, while indirect costs include time, stress, travel to test centers, and threats to livelihood for failing a high-stakes examination. Physicians want the high-stakes exam eliminated.
Relevance to practice
Physicians often feel that the MOC has little relevance to their practice, which fuels a sense of resentment toward boards that they believe are dominated by physicians who no longer practice. Subspecialists feel farther away from general practice and the base exams. Generalists feel that the exams miss the points of their daily practice.
Lack of data to show improved quality of care
Physicians want to know that the MOC is worth their time, effort, and money because it improves patient care. To date, however, empirical or clinical data on patient outcomes are absent or ambiguous; most studies lack high-level data or do not investigate the MOC requirements. Physicians want to know what the best MOC practices are, what improves care, and that practices that make no difference will be discarded. In addition, they want timely knowledge alerts when evidence changes.
Relationship to licensing, employment, privileging, credentialing, and reimbursement
Hospitals, insurers, and states increasingly—and inappropriately—use board certification as the primary (sometimes only) default measure of a physician’s fitness for patient care. Physicians without board certification often are denied hospital privileges, inclusion in insurance panels, and even medical licenses. This changes certification from a voluntary physician self-improvement exercise into a can’t-earn-a-living-without-it cudgel.
Variation
Boards vary significantly in their MOC requirements and costs. The importance of an equal standard across all boards is a clear theme among physician concerns.
Role and authority of the ABMS and related boards
Many physicians are frustrated with the perceived autocratic nature of their boards—boards that lack transparency, do not solicit or allow input from practicing physicians, and are unresponsive to physician concerns.
According to Susan Ramin, MD, ABOG Associate Executive Director, ABOG is leading in a number of these areas, including:
- rapidly disseminating clinical information on emerging topics, such as Zika virus infection and opioid misuse
- offering physician choice of testing categories
- exempting high scorers from the secured written exam, which saved physicians a total of $881,000 in exam fees
- crediting physicians for what they already are doing, including serving on maternal mortality review committees, participating in registries, and participating in the Alliance for Innovation on Maternal Health (AIM)
- providing Lifelong Learning and Self-Assessment (LLSA) articles that, according to 90% of diplomates surveyed, are beneficial to their clinical practice (FIGURE).1,2
Our colleague physicians are not so lucky. In a 2015 New England Journal of Medicine Perspective, one physician called out the American Board of Internal Medicine as “a private, self-appointed certifying organization,” a not-for-profit organization that has “grown into a $55-million-per-year business.”3 He concluded that “many physicians are waking up to the fact that our profession is increasingly controlled by people not directly involved in patient care who have lost contact with the realities of day-to-day clinical practice.”3
State and society responses to MOC requirements
Frustration with an inability to resolve these concerns has grown steadily, bubbling over into state governments. The American Medical Association developed “model state legislation intended to prohibit hospitals, health care insurers, and state boards of medicine and osteopathic medicine from requiring participation in MOC processes as a condition of credentialing, privileging, insurance panel participation, licensure, or licensure renewal.”4
Some states are proposing or have enacted legislation that prohibits the use of MOC as a criterion for licensure, privileging, employment, reimbursement, and/or insurance panel participation. Eight states (Arizona, Georgia, Kentucky, Maryland, Maine, Missouri, Oklahoma, Tennessee) have enacted laws to prohibit the use of MOC for initial and renewal licensure decisions. Many states are actively considering MOC-related legislation, including Alaska, Florida, Iowa, Indiana, Maryland, Massachusetts, Michigan, Missouri, New Hampshire, New York, Ohio, Oklahoma, Rhode Island, South Carolina, Tennessee, Utah, Washington, and Wisconsin.
Legislation is not the only outlet for physician frustration. Some medical specialty societies are considering dropping board certification as a membership requirement; physicians are exploring developing alternative boards; and some physicians are defying the board certification requirement altogether, with thousands signing anti-MOC petitions.
ACOG asserts importance of maintaining self-regulation
While other specialties are actively advocating state legislation, ACOG and ABOG have worked together to oppose state legislation, believing that physician self-regulation is paramount. In fact, in 2017, ACOG and ABOG issued a joint statement urging state lawmakers to “not interfere with our decades of successful self-regulation and to realize that each medical society has its own experience with its MOC program.”5
Negotiations lead to new initiative
This brings us to an interesting situation. ACOG’s Executive Vice President and CEO Hal Lawrence III, MD, was tapped (in his position as Chair of the Specialty Society CEO Consortium) to represent physician specialties in negotiations and discussions with the boards, which were represented by Lois Nora, MD, JD, President and CEO of the ABMS, and state medical societies, represented by Donald Palmisano Jr, JD, Executive Director and CEO of the Medical Association of Georgia. Many state medical societies, boards, and physician specialty organizations participated in these meetings.
Throughout months of debate, Dr. Lawrence urged his colleagues to stay at the table and do the hard work of reaching an agreement, rather than ask politicians to solve medicine’s problems. This approach was leveraged by the serious efforts and threats of state legislation, which brought the boards to the table. In August 2017, 41 state medical societies and 33 national medical specialty societies wrote to Dr. Nora expressing their concerns that “professional self-regulation is under attack. Concerns regarding the usefulness of the high-stakes exam, the exorbitant costs of the MOC process, and the lack of transparent communication from the certifying boards have led to damaging the MOC brand, and creating state-based attacks on the MOC process.”6
In December 2017, Dr. Lawrence and Mr. Palmisano led a meeting of principals from the national medical specialty societies and state medical societies with leaders of ABMS and 8 specialty boards, including ABOG, an opportunity to secure meaningful change. Dr. Lawrence began by stressing that the interests of physicians and patients would be best served by all parties coming together and collaborating on a meaningful solution, to repair trust and preserve physician self-regulation.
Dr. Ramin presented ABOG’s approach to continuous certification, lifelong learning, and self-assessment. The American Board of Urology and the American Board of Psychiatry and Neurology indicated that they were basing important changes in their MOC process on ABOG’s work, including using 5 modules (1 general and 4 specific to the physician’s practice) and multiple open-book mini-exams based on selected journal articles as an alternative to the 10-year MOC exam.
The Vision Initiative. At that meeting and others, the ABMS and other boards heard physicians’ candid and sometimes blunt concerns. Dr. Nora spoke to the recently announced Continuing Board Certification: Vision for the Future program, also known as the “Vision Initiative,” a process designed to fundamentally rebuild the continuing certification process with input and guidance from practicing physicians. Physician response seemed uniform: Seeing is believing.
Importantly, all participants at the December meeting agreed to work together to rebuild trust and ensure professionalism and professional self-regulation, reflected in this Statement of Shared Purpose:
ABMS certifying boards and national medical specialty societies will collaborate to resolve differences in the process of ongoing certification and to fulfill the principles of professional self-regulation, achieving appropriate standardization, and assuring that ongoing certification is relevant to the practices of physicians without undue burden. Furthermore, the boards and societies, and their organizations (ABMS and CMSS [Council of Medical Specialty Societies]), will undertake necessary changes in a timely manner, and will commit to ongoing communication with state medical associations to solicit their input.4
Two ObGyns participating in the Vision Initiative are Haywood Brown, MD, ACOG’s Immediate Past President, and George Wendel, MD, ABOG’s Executive Director. The Vision Initiative is composed of 3 parts. Part 1, Organization, is complete. The committee is currently working on part 2, Envisioning the Future, an information-gathering component that includes physician surveys, hearings, open solicited input, and identifying new and better approaches. After the final report is delivered to the ABMS in February 2019, part 3, Implementation, will begin.
The Vision Initiative offers physicians an important opportunity to help shape the future of continuing education and certification. ObGyns and other physicians should consider reviewing and commenting on the draft report, due in November, during the public comment period.

CDC apps specific for ObGyns
The Centers for Disease Control and Prevention (CDC) is a US federal agency under the Department of Health and Human Services. It is the nation’s leading public health institute. Its main goal is to save lives and protect people from health, safety, and security threats. The CDC website lists 25 no-cost applications that the agency has developed: https://www.cdc.gov/mobile/mobileapp.html.
This review will focus on 3 CDC apps (Table) that I feel are useful to ObGyn health care providers: Prevent Group B Strep (GBS), STD Tx Guide, and US Medical Eligibility Criteria for Contraceptive Use. In fact, in an evaluation of contraception apps for providers of family planning services, US Medical Eligibility Criteria for Contraceptive Use was one of the highest scoring apps.1 I will evaluate each app by a shortened version of the APPLICATIONS scoring system, APPLI (app comprehensiveness, price, platform, literature use, and important special features).2 I commend the CDC for developing these useful tools to assist health care providers.

Liver enzymes: No trivial elevations, even if asymptomatic
Elevated levels of circulating enzymes that are frequently of hepatic origin (aminotransferases and alkaline phosphatase) and bilirubin in the absence of symptoms are common in clinical practice. A dogmatic but true statement holds that there are no trivial elevations in these substances. All persistent elevations of liver enzymes need a methodical evaluation and an appropriate working diagnosis.1
Here, we outline a framework for the workup and treatment of common causes of liver enzyme elevations.
PATTERN OF ELEVATION: CHOLESTATIC OR HEPATOCELLULAR
Based on the pattern of elevation, causes of elevated liver enzymes can be sorted into disorders of cholestasis and disorders of hepatocellular injury (Table 1).1
Cholestatic disorders tend to cause elevations in alkaline phosphatase, bilirubin, and gamma-glutamyl transferase (GGT).
Hepatocellular injury raises levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST).
HOW SHOULD ABNORMAL RESULTS BE EVALUATED?
When approaching liver enzyme elevations, the clinician should develop a working differential diagnosis based on the medical and social history and physical examination.
Think about alcohol, drugs, and fat
The most common causes of liver enzyme elevation are alcohol toxicity, medication overdose, and fatty liver disease.
Alcohol intake should be ascertained. “Significant” consumption is defined as more than 21 drinks per week in men or more than 14 drinks per week in women, over a period of at least 2 years.2
The exact pathogenesis of alcoholic hepatitis is incompletely understood, but alcohol is primarily metabolized by the liver, and damage likely occurs during metabolism of the ingested alcohol. AST elevations tend to be higher than ALT elevations; the reason is ascribed to hepatic deficiency of pyridoxal 5´-phosphate, a cofactor of the enzymatic activity of ALT, which leads to a lesser increase in ALT than in AST.
Alcoholic liver disease can be difficult to diagnose, as many people are initially reluctant to fully disclose how much they drink, but it should be suspected when the ratio of AST to ALT is 2 or greater.
In a classic study, a ratio greater than 2 was found in 70% of patients with alcoholic hepatitis and cirrhosis, compared with 26% of patients with postnecrotic cirrhosis, 8% with chronic hepatitis, 4% with viral hepatitis, and none with obstructive jaundice.3 Importantly, the disorder is often correctable if the patient is able to remain abstinent from alcohol over time.
A detailed medication history is important and should focus especially on recently added medications, dosage changes, medication overuse, and use of nonprescription drugs and herbal supplements. Common medications that affect liver enzyme levels include statins, which cause hepatic dysfunction primarily during the first 3 months of therapy, nonsteroidal anti-inflammatory drugs, antiepileptic drugs, antibiotics, anabolic steroids, and acetaminophen (Table 2).1 Use of illicit drugs and herbal remedies should be discussed, as they may cause toxin-mediated hepatitis.
Although inflammation from drug toxicity will resolve if the offending agent is discontinued, complete recovery may take weeks to months.4
A pertinent social history includes exposure to environmental hepatotoxins such as amatoxin (contained in some wild mushrooms) and occupational hazards (eg, vinyl chloride). Risk factors for viral hepatitis should be evaluated, including intravenous drug use, blood transfusions, unprotected sexual contact, organ transplant, perinatal transmission, and a history of work in healthcare facilities or travel to regions in which hepatitis A or E is endemic.
The medical and family history should include details of associated conditions, such as:
- Right heart failure (a cause of congestive hepatopathy)
- Metabolic syndrome (associated with fatty liver disease)
- Inflammatory bowel disease and primary sclerosing cholangitis
- Early-onset emphysema and alpha-1 antitrypsin deficiency.
The physical examination should be thorough, with emphasis on the abdomen, and search for stigmata of advanced liver disease such as hepatomegaly, splenomegaly, ascites, edema, spider angiomata, jaundice, and asterixis. Any patient with evidence of chronic liver disease should be referred to a subspecialist for further evaluation.
Further diagnostic workup
Abnormal liver enzyme findings or physical examination findings should direct the subsequent diagnostic workup with laboratory testing and imaging.5
For cholestasis. If laboratory data are consistent with cholestasis or abnormal bile flow, it should be further characterized as extrahepatic or intrahepatic. Common causes of extrahepatic cholestasis include biliary tree obstruction due to stones or malignancy, often visualized as intraductal biliary dilation on ultrasonography of the right upper quadrant. Common causes of intrahepatic cholestasis include viral and alcoholic hepatitis, nonalcoholic steatohepatitis, certain drugs and toxins such as alkylated steroids and herbal medications, infiltrative diseases such as amyloid, sarcoid, lymphoma, and tuberculosis, and primary biliary cholangitis.
Abnormal findings on ultrasonography should be further pursued with advanced imaging, ie, computed tomography or magnetic resonance cholangiopancreatography (MRCP). The confirmation of a lesion on imaging is often followed by endoscopic retrograde cholangiopancreatography (ERCP) in an attempt to obtain biopsy samples, remove obstructions, and place therapeutic stents. In instances when endoscopic attempts fail to relieve the obstruction, surgical referral may be appropriate.
For nonhepatobiliary problems. Depending on clinical presentation, it may also be important to consider nonhepatobiliary causes of elevated liver enzymes.
Alkaline phosphatase is found in many other tissue types, including bone, kidney, and the placenta, and can be elevated during pregnancy, adolescence, and even after fatty meals due to intestinal release.6 After screening for the aforementioned physiologic conditions, isolated elevated alkaline phosphatase should be further evaluated by obtaining GGT or 5-nucleotidase levels, which are more specifically of hepatic origin. If these levels are within normal limits, further evaluation for conditions of bone growth and cellular turnover such as Paget disease, hyperparathyroidism, and malignancy should be considered. Specifically, Stauffer syndrome should be considered when there is a paraneoplastic rise in the alkaline phosphatase level in the setting of renal cell carcinoma without liver metastases.
AST and ALT levels may also be elevated in clinical situations and syndromes unrelated to liver disease. Rhabdomyolysis, for instance, may be associated with elevations of AST in more than 90% of cases, and ALT in more than 75%.7 Markers of muscle injury including serum creatine kinase should be obtained in the setting of heat stroke, muscle weakness, strenuous activity, or seizures, as related elevations in AST and ALT may not always be clinically indicative of liver injury.
Given the many conditions that may cause elevated liver enzymes, evaluation and treatment should focus on identifying and removing offending agents and targeting the underlying process with appropriate medical therapy.
FATTY LIVER
With rates of obesity and type 2 diabetes on the rise in the general population, identifying and treating nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) require increased awareness and close coordination between primary care providers and subspecialists.
According to current estimates, up to one-third of the US population (100 million people) may have NAFLD, and 1% to 3% of the population (4–6 million people) likely have NASH, defined as steatosis with inflammation. Development of NASH places patients at a significantly higher risk of fibrosis, hepatocellular injury, and cancer.8
NAFLD is more common in men than in women. It is present in around 80% to 90% of obese adults, two-thirds of adults with type 2 diabetes, and many people with hyperlipidemia. It is also becoming more common in children, with 40% to 70% of obese children likely having some element of NAFLD.
Diagnosis of fatty liver
Although liver enzymes are more likely to be abnormal in individuals with NAFLD, many individuals with underlying NAFLD may have normal laboratory evaluations. ALT may be elevated in only up to 20% of cases and does not likely correlate with the level of underlying liver damage, although increasing GGT may serve as a marker of fibrosis over time.9–11 In contrast to alcohol injury, however, the AST-ALT ratio is usually less than 1.0.
Noninvasive tools for diagnosing NAFLD include the NAFLD fibrosis score, which incorporates age, hyperglycemia, body mass index, platelet count, albumin level, and AST-ALT ratio. This and related scoring algorithms may be useful in differentiating patients with minimal fibrosis from those with advanced fibrosis.12,13
Ultrasonography is a first-line diagnostic test for steatosis, although it may demonstrate fatty infiltration only around 60% of the time. Computed tomography and magnetic resonance imaging are more sensitive, but costlier. Transient elastography (FibroScan; Echosens, Paris, France) has become more popular and has been shown to correlate with findings on liver biopsy in diagnosing or excluding advanced liver fibrosis.14,15
The gold standard for diagnosing NAFLD and NASH is identifying fat-laden hepatocytes or portal inflammation on biopsy; however, biopsy is generally reserved for cases in which the diagnosis remains uncertain.
Behavioral treatment
The primary treatment for NAFLD consists of behavioral modification including weight loss, exercise, and adherence to a low-fat diet, in addition to tight glycemic control and treatment of any underlying lipid abnormalities. Studies have shown that a reduction of 7% to 10% of body weight is associated with a decrease in the inflammation of NAFLD, though no strict guidelines have been established.16
Given the prevalence of NAFLD and the need for longitudinal treatment, primary care physicians will play a significant role in long-term monitoring and management of patients with fatty liver disease.
OTHER DISORDERS OF LIVER FUNCTION
Hereditary hemochromatosis
Hereditary hemochromatosis is the most common inherited liver disorder in adults of European descent,17 and can be effectively treated if discovered early. But its clinical diagnosis can be challenging, as many patients have no symptoms at presentation despite abnormal liver enzyme levels. Early symptoms may include severe fatigue, arthralgias, and, in men, impotence, before the appearance of the classic triad of “bronze diabetes” with cirrhosis, diabetes, and darkening of the skin.18
If hemochromatosis is suspected, laboratory tests should include a calculation of percent transferrin saturation, with saturation greater than 45% warranting serum ferritin measurement to evaluate for iron overload (ferritin > 200–300 ng/mL in men, > 150–200 ng/mL in women).19 If iron overload is confirmed, referral to a gastroenterologist is recommended.
Genetic evaluation is often pursued, but patients may ultimately require liver biopsy regardless of the findings, as some patients homozygous for the HFE mutation C282Y may not have clinical hemochromatosis, whereas others with hereditary hemochromatosis may not have the HFE mutation.
Therapeutic phlebotomy is the treatment of choice, and most patients tolerate it well.
Chronic hepatitis B virus and hepatitis C virus infections
Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are common in the United States, with HBV affecting more than 1 million people and HCV affecting an estimated 3.5 million.
Chronic HCV infection. Direct-acting antiviral drugs have revolutionized HCV treatment and have led to a sustained viral response and presumed cure at 12 weeks in more than 95% of cases across all HCV genotypes.20 Given the recent development of effective and well-tolerated treatments, primary care physicians have assumed a pivotal role in screening for HCV.
The American Association for the Study of Liver Diseases and the Infectious Diseases Society of America21 recommend screening for HCV in people who have risk factors for it, ie:
- HCV exposure
- HIV infection
- Behavioral or environmental risks for contracting the virus such as intravenous drug use or incarceration
- Birth between 1945 and 1965 (one-time testing).
If HCV antibody screening is positive, HCV RNA should be obtained to quantify the viral load and confirm active infection, and genotype testing should be performed to guide treatment. Among the 6 most common HCV genotypes, genotype 1 is the most common in North America, accounting for over 70% of cases in the United States.
Although recommendations and therapies are constantly evolving, the selection of a treatment regimen and the duration of therapy are determined by viral genotype, history of prior treatment, stage of liver fibrosis, potential drug interactions, and frequently, medication cost and insurance coverage.
HBV infection. The treatment for acute HBV infection is generally supportive, though viral suppression with tenofovir or entecavir may be required for those who develop coagulopathy, bilirubinemia, or liver failure. Treatment of chronic HBV infection may not be required and is generally considered for those with elevated ALT, high viral load, or evidence of liver fibrosis on noninvasive measurements such as transient elastography.
Autoimmune hepatitis
Autoimmune causes of liver enzyme elevations should also be considered during initial screening. Positive antinuclear antibody and positive antismooth muscle antibody tests are common in cases of autoimmune hepatitis.22 Autoimmune hepatitis affects women more often than men, with a ratio of 4:1. The peaks of incidence occur during adolescence and between ages 30 and 45.23
Primary biliary cholangitis
Additionally, an elevated alkaline phosphatase level should raise concern for underlying primary biliary cholangitis (formerly called primary biliary cirrhosis), an autoimmune disorder that affects the small and medium intrahepatic bile ducts. Diagnosis of primary biliary cholangitis can be assisted by a positive test for antimitochondrial antibody, present in almost 90% of patients.24
Primary sclerosing cholangitis
Elevated alkaline phosphatase is also the hallmark of primary sclerosing cholangitis, which is associated with inflammatory bowel disease.25 Primary sclerosing cholangitis is characterized by inflammation and fibrosis of the intrahepatic and extrahepatic bile ducts, which are visualized on MRCP and confirmed by biopsy if needed.
REFERRAL
Subspecialty referral should be considered if the cause remains ambiguous or unknown, if there is concern for a rare hepatic disorder such as an autoimmune condition, Wilson disease, or alpha-1 antitrypsin deficiency, or if there is evidence of advanced or chronic liver disease.
Primary care physicians are at the forefront of detecting and diagnosing liver disease, and close coordination with subspecialists will remain crucial in delivering patient care.

Elevated levels of circulating enzymes that are frequently of hepatic origin (aminotransferases and alkaline phosphatase) and bilirubin in the absence of symptoms are common in clinical practice. A dogmatic but true statement holds that there are no trivial elevations in these substances. All persistent elevations of liver enzymes need a methodical evaluation and an appropriate working diagnosis.1
Here, we outline a framework for the workup and treatment of common causes of liver enzyme elevations.
PATTERN OF ELEVATION: CHOLESTATIC OR HEPATOCELLULAR
Based on the pattern of elevation, causes of elevated liver enzymes can be sorted into disorders of cholestasis and disorders of hepatocellular injury (Table 1).1
Cholestatic disorders tend to cause elevations in alkaline phosphatase, bilirubin, and gamma-glutamyl transferase (GGT).
Hepatocellular injury raises levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST).
HOW SHOULD ABNORMAL RESULTS BE EVALUATED?
When approaching liver enzyme elevations, the clinician should develop a working differential diagnosis based on the medical and social history and physical examination.
Think about alcohol, drugs, and fat
The most common causes of liver enzyme elevation are alcohol toxicity, medication overdose, and fatty liver disease.
Alcohol intake should be ascertained. “Significant” consumption is defined as more than 21 drinks per week in men or more than 14 drinks per week in women, over a period of at least 2 years.2
The exact pathogenesis of alcoholic hepatitis is incompletely understood, but alcohol is primarily metabolized by the liver, and damage likely occurs during metabolism of the ingested alcohol. AST elevations tend to be higher than ALT elevations; the reason is ascribed to hepatic deficiency of pyridoxal 5´-phosphate, a cofactor of the enzymatic activity of ALT, which leads to a lesser increase in ALT than in AST.
Alcoholic liver disease can be difficult to diagnose, as many people are initially reluctant to fully disclose how much they drink, but it should be suspected when the ratio of AST to ALT is 2 or greater.
In a classic study, a ratio greater than 2 was found in 70% of patients with alcoholic hepatitis and cirrhosis, compared with 26% of patients with postnecrotic cirrhosis, 8% with chronic hepatitis, 4% with viral hepatitis, and none with obstructive jaundice.3 Importantly, the disorder is often correctable if the patient is able to remain abstinent from alcohol over time.
A detailed medication history is important and should focus especially on recently added medications, dosage changes, medication overuse, and use of nonprescription drugs and herbal supplements. Common medications that affect liver enzyme levels include statins, which cause hepatic dysfunction primarily during the first 3 months of therapy, nonsteroidal anti-inflammatory drugs, antiepileptic drugs, antibiotics, anabolic steroids, and acetaminophen (Table 2).1 Use of illicit drugs and herbal remedies should be discussed, as they may cause toxin-mediated hepatitis.
Although inflammation from drug toxicity will resolve if the offending agent is discontinued, complete recovery may take weeks to months.4
A pertinent social history includes exposure to environmental hepatotoxins such as amatoxin (contained in some wild mushrooms) and occupational hazards (eg, vinyl chloride). Risk factors for viral hepatitis should be evaluated, including intravenous drug use, blood transfusions, unprotected sexual contact, organ transplant, perinatal transmission, and a history of work in healthcare facilities or travel to regions in which hepatitis A or E is endemic.
The medical and family history should include details of associated conditions, such as:
- Right heart failure (a cause of congestive hepatopathy)
- Metabolic syndrome (associated with fatty liver disease)
- Inflammatory bowel disease and primary sclerosing cholangitis
- Early-onset emphysema and alpha-1 antitrypsin deficiency.
The physical examination should be thorough, with emphasis on the abdomen, and search for stigmata of advanced liver disease such as hepatomegaly, splenomegaly, ascites, edema, spider angiomata, jaundice, and asterixis. Any patient with evidence of chronic liver disease should be referred to a subspecialist for further evaluation.
Further diagnostic workup
Abnormal liver enzyme findings or physical examination findings should direct the subsequent diagnostic workup with laboratory testing and imaging.5
For cholestasis. If laboratory data are consistent with cholestasis or abnormal bile flow, it should be further characterized as extrahepatic or intrahepatic. Common causes of extrahepatic cholestasis include biliary tree obstruction due to stones or malignancy, often visualized as intraductal biliary dilation on ultrasonography of the right upper quadrant. Common causes of intrahepatic cholestasis include viral and alcoholic hepatitis, nonalcoholic steatohepatitis, certain drugs and toxins such as alkylated steroids and herbal medications, infiltrative diseases such as amyloid, sarcoid, lymphoma, and tuberculosis, and primary biliary cholangitis.
Abnormal findings on ultrasonography should be further pursued with advanced imaging, ie, computed tomography or magnetic resonance cholangiopancreatography (MRCP). The confirmation of a lesion on imaging is often followed by endoscopic retrograde cholangiopancreatography (ERCP) in an attempt to obtain biopsy samples, remove obstructions, and place therapeutic stents. In instances when endoscopic attempts fail to relieve the obstruction, surgical referral may be appropriate.
For nonhepatobiliary problems. Depending on clinical presentation, it may also be important to consider nonhepatobiliary causes of elevated liver enzymes.
Alkaline phosphatase is found in many other tissue types, including bone, kidney, and the placenta, and can be elevated during pregnancy, adolescence, and even after fatty meals due to intestinal release.6 After screening for the aforementioned physiologic conditions, isolated elevated alkaline phosphatase should be further evaluated by obtaining GGT or 5-nucleotidase levels, which are more specifically of hepatic origin. If these levels are within normal limits, further evaluation for conditions of bone growth and cellular turnover such as Paget disease, hyperparathyroidism, and malignancy should be considered. Specifically, Stauffer syndrome should be considered when there is a paraneoplastic rise in the alkaline phosphatase level in the setting of renal cell carcinoma without liver metastases.
AST and ALT levels may also be elevated in clinical situations and syndromes unrelated to liver disease. Rhabdomyolysis, for instance, may be associated with elevations of AST in more than 90% of cases, and ALT in more than 75%.7 Markers of muscle injury including serum creatine kinase should be obtained in the setting of heat stroke, muscle weakness, strenuous activity, or seizures, as related elevations in AST and ALT may not always be clinically indicative of liver injury.
Given the many conditions that may cause elevated liver enzymes, evaluation and treatment should focus on identifying and removing offending agents and targeting the underlying process with appropriate medical therapy.

Common causes of intrahepatic cholestasis include viral and alcoholic hepatitis, nonalcoholic steatohepatitis, certain drugs and toxins such as alkylated steroids and herbal medications, infiltrative diseases such as amyloid, sarcoid, lymphoma, and tuberculosis, and primary biliary cholangitis.
Abnormal findings on ultrasonography should be further pursued with advanced imaging, ie, computed tomography or magnetic resonance cholangiopancreatography (MRCP). The confirmation of a lesion on imaging is often followed by endoscopic retrograde cholangiopancreatography (ERCP) in an attempt to obtain biopsy samples, remove obstructions, and place therapeutic stents. In instances when endoscopic attempts fail to relieve the obstruction, surgical referral may be appropriate.
For nonhepatobiliary problems. Depending on clinical presentation, it may also be important to consider nonhepatobiliary causes of elevated liver enzymes.
Alkaline phosphatase is found in many other tissue types, including bone, kidney, and the placenta, and can be elevated during pregnancy, adolescence, and even after fatty meals due to intestinal release.6 After screening for the aforementioned physiologic conditions, isolated elevated alkaline phosphatase should be further evaluated by obtaining GGT or 5-nucleotidase levels, which are more specifically of hepatic origin. If these levels are within normal limits, further evaluation for conditions of bone growth and cellular turnover such as Paget disease, hyperparathyroidism, and malignancy should be considered. Specifically, Stauffer syndrome should be considered when there is a paraneoplastic rise in the alkaline phosphatase level in the setting of renal cell carcinoma without liver metastases.
AST and ALT levels may also be elevated in clinical situations and syndromes unrelated to liver disease. Rhabdomyolysis, for instance, may be associated with elevations of AST in more than 90% of cases, and ALT in more than 75%.7 Markers of muscle injury including serum creatine kinase should be obtained in the setting of heat stroke, muscle weakness, strenuous activity, or seizures, as related elevations in AST and ALT may not always be clinically indicative of liver injury.
Given the many conditions that may cause elevated liver enzymes, evaluation and treatment should focus on identifying and removing offending agents and targeting the underlying process with appropriate medical therapy.
FATTY LIVER
With rates of obesity and type 2 diabetes on the rise in the general population, identifying and treating nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) require increased awareness and close coordination between primary care providers and subspecialists.
According to current estimates, up to one-third of the US population (100 million people) may have NAFLD, and 1% to 3% of the population (4–6 million people) likely have NASH, defined as steatosis with inflammation. Development of NASH places patients at a significantly higher risk of fibrosis, hepatocellular injury, and cancer.8
NAFLD is more common in men than in women. It is present in around 80% to 90% of obese adults, two-thirds of adults with type 2 diabetes, and many people with hyperlipidemia. It is also becoming more common in children, with 40% to 70% of obese children likely having some element of NAFLD.
Diagnosis of fatty liver
Although liver enzymes are more likely to be abnormal in individuals with NAFLD, many individuals with underlying NAFLD may have normal laboratory evaluations. ALT may be elevated in only up to 20% of cases and does not likely correlate with the level of underlying liver damage, although increasing GGT may serve as a marker of fibrosis over time.9–11 In contrast to alcohol injury, however, the AST-ALT ratio is usually less than 1.0.
Noninvasive tools for diagnosing NAFLD include the NAFLD fibrosis score, which incorporates age, hyperglycemia, body mass index, platelet count, albumin level, and AST-ALT ratio. This and related scoring algorithms may be useful in differentiating patients with minimal fibrosis from those with advanced fibrosis.12,13
Ultrasonography is a first-line diagnostic test for steatosis, although it may demonstrate fatty infiltration only around 60% of the time. Computed tomography and magnetic resonance imaging are more sensitive, but costlier. Transient elastography (FibroScan; Echosens, Paris, France) has become more popular and has been shown to correlate with findings on liver biopsy in diagnosing or excluding advanced liver fibrosis.14,15
The gold standard for diagnosing NAFLD and NASH is identifying fat-laden hepatocytes or portal inflammation on biopsy; however, biopsy is generally reserved for cases in which the diagnosis remains uncertain.
Behavioral treatment
The primary treatment for NAFLD consists of behavioral modification including weight loss, exercise, and adherence to a low-fat diet, in addition to tight glycemic control and treatment of any underlying lipid abnormalities. Studies have shown that a reduction of 7% to 10% of body weight is associated with a decrease in the inflammation of NAFLD, though no strict guidelines have been established.16
Given the prevalence of NAFLD and the need for longitudinal treatment, primary care physicians will play a significant role in long-term monitoring and management of patients with fatty liver disease.
OTHER DISORDERS OF LIVER FUNCTION
Hereditary hemochromatosis
Hereditary hemochromatosis is the most common inherited liver disorder in adults of European descent,17 and can be effectively treated if discovered early. But its clinical diagnosis can be challenging, as many patients have no symptoms at presentation despite abnormal liver enzyme levels. Early symptoms may include severe fatigue, arthralgias, and, in men, impotence, before the appearance of the classic triad of “bronze diabetes” with cirrhosis, diabetes, and darkening of the skin.18
If hemochromatosis is suspected, laboratory tests should include a calculation of percent transferrin saturation, with saturation greater than 45% warranting serum ferritin measurement to evaluate for iron overload (ferritin > 200–300 ng/mL in men, > 150–200 ng/mL in women).19 If iron overload is confirmed, referral to a gastroenterologist is recommended.
Genetic evaluation is often pursued, but patients may ultimately require liver biopsy regardless of the findings, as some patients homozygous for the HFE mutation C282Y may not have clinical hemochromatosis, whereas others with hereditary hemochromatosis may not have the HFE mutation.
Therapeutic phlebotomy is the treatment of choice, and most patients tolerate it well.
Chronic hepatitis B virus and hepatitis C virus infections
Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are common in the United States, with HBV affecting more than 1 million people and HCV affecting an estimated 3.5 million.
Chronic HCV infection. Direct-acting antiviral drugs have revolutionized HCV treatment and have led to a sustained viral response and presumed cure at 12 weeks in more than 95% of cases across all HCV genotypes.20 Given the recent development of effective and well-tolerated treatments, primary care physicians have assumed a pivotal role in screening for HCV.
The American Association for the Study of Liver Diseases and the Infectious Diseases Society of America21 recommend screening for HCV in people who have risk factors for it, ie:
- HCV exposure
- HIV infection
- Behavioral or environmental risks for contracting the virus such as intravenous drug use or incarceration
- Birth between 1945 and 1965 (one-time testing).
If HCV antibody screening is positive, HCV RNA should be obtained to quantify the viral load and confirm active infection, and genotype testing should be performed to guide treatment. Among the 6 most common HCV genotypes, genotype 1 is the most common in North America, accounting for over 70% of cases in the United States.
Although recommendations and therapies are constantly evolving, the selection of a treatment regimen and the duration of therapy are determined by viral genotype, history of prior treatment, stage of liver fibrosis, potential drug interactions, and frequently, medication cost and insurance coverage.
HBV infection. The treatment for acute HBV infection is generally supportive, though viral suppression with tenofovir or entecavir may be required for those who develop coagulopathy, bilirubinemia, or liver failure. Treatment of chronic HBV infection may not be required and is generally considered for those with elevated ALT, high viral load, or evidence of liver fibrosis on noninvasive measurements such as transient elastography.
Autoimmune hepatitis
Autoimmune causes of liver enzyme elevations should also be considered during initial screening. Positive antinuclear antibody and positive antismooth muscle antibody tests are common in cases of autoimmune hepatitis.22 Autoimmune hepatitis affects women more often than men, with a ratio of 4:1. The peaks of incidence occur during adolescence and between ages 30 and 45.23
Primary biliary cholangitis
Additionally, an elevated alkaline phosphatase level should raise concern for underlying primary biliary cholangitis (formerly called primary biliary cirrhosis), an autoimmune disorder that affects the small and medium intrahepatic bile ducts. Diagnosis of primary biliary cholangitis can be assisted by a positive test for antimitochondrial antibody, present in almost 90% of patients.24
Primary sclerosing cholangitis
Elevated alkaline phosphatase is also the hallmark of primary sclerosing cholangitis, which is associated with inflammatory bowel disease.25 Primary sclerosing cholangitis is characterized by inflammation and fibrosis of the intrahepatic and extrahepatic bile ducts, which are visualized on MRCP and confirmed by biopsy if needed.
REFERRAL
Subspecialty referral should be considered if the cause remains ambiguous or unknown, if there is concern for a rare hepatic disorder such as an autoimmune condition, Wilson disease, or alpha-1 antitrypsin deficiency, or if there is evidence of advanced or chronic liver disease.
Primary care physicians are at the forefront of detecting and diagnosing liver disease, and close coordination with subspecialists will remain crucial in delivering patient care.

KEY POINTS
- Disorders of hepatocellular injury tend to elevate levels of aminotransferases, whereas cholestatic disorders cause elevations of alkaline phosphatase and bilirubin.
- The three most common causes of liver enzyme elevation are alcohol toxicity, medication overdose, and fatty liver disease.
- Other disorders of liver dysfunction include hereditary hemochromatosis, viral hepatitis, autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis, and alpha-1 antitrypsin disease.
- Nonhepatic causes of elevated “liver enzymes” also need to be considered. For instance, rhabdomyolysis causes elevations in aminotransferase levels.
