Clinician Reviews

HAMBURG, GERMANY – An upcoming joint society statement on hyperglycemic emergencies in adults with diabetes will de-emphasize glucose from the diagnostic criteria for diabetic ketoacidosis (DKA), along with many other updates to the last statement on the topic, published 14 years ago.  

Based on extensive literature reviews and observations of current trends, the new document – due to be published soon – will cover diagnosis and management of the two most serious acute hyperglycemic emergencies seen in adults, DKA and hyperosmolar hyperglycemic state (HHS).

New to the 2023 version will be a strong emphasis on the excess morbidity and mortality risks associated with the increasingly common “hybrid” presentation of the two conditions together, now seen in about a third of cases.

The new report will also more strongly urge clinicians to investigate why the person experienced the emergency.

While new-onset diabetes and infection are recognized precipitating causes for DKA, insulin omission related to finances, mental health, and social determinants should be identified, and patients directed to appropriate resources, said experts previewing the upcoming new report at the annual meeting of the European Association for the Study of Diabetes.

“The challenge is, although we were making progress for a long time in terms of those hyperglycemic crises, we’ve really plateaued and there are still people being admitted in large numbers, and when you look more globally even more so,” said American Diabetes Association Chief Science and Medical Officer Robert A. Gabbay, MD, PhD.

The new consensus report will be jointly endorsed by the ADA, the EASD, the American Association of Clinical Endocrinology, the Diabetes Technology Society, and the Joint British Diabetes Societies for Inpatient Care. The previous consensus statement on the subject was published in 2009 by the ADA alone.
 

New DKA and HHS definitions reflect emerging trends

The statement will revise the definition of DKA, partly spurred by the increasing occurrence and recognition of euglycemic ketoacidosis arising from the use of sodium-glucose cotransporter 2 (SGLT2) inhibitors. For all patients with hyperglycemic crisis, the hyperglycemia cutoff is now lowered to 200 mg/dL (11.1 mmol/L) from the previous 250 mg/dL.

However, the glucose cutoff has been removed entirely for people with a history of diabetes.

“Both of these changes are recognizing the wide range of glucose levels at the presence of DKA. Approximately 10% of DKA occurs with euglycemia or near-normoglycemia,” noted coauthor Shivani Misra, MD, PhD, senior clinical lecturer and honorary consultant in Metabolic Medicine at Imperial College, London.

For assessing ketosis in DKA, the new statement strongly recommends use of beta-hydroxybutyrate – either via point-of-care test or serum level measured in a laboratory – with a low cutoff of ≥ 3.0 mmol/L. Alternatively, a urine ketone strip value of 2+ or greater can be used.

However, beta-hydroxybutyrate testing is more widely available now than it was in 2009 and is strongly preferred over urine ketone measurement because it’s the predominant ketone during acidosis. Moreover, urine acetoacetate – measured by the strips – paradoxically increases during resolution of DKA, and drug interferences can occur with urine ketone measurement, Dr. Misra noted.

Metabolic acidosis is now defined as a pH < 7.3 and/or a bicarbonate concentration < 18 mmol/L, up from 15 in some prior guidelines including the United Kingdom’s. Also, anion gap has been removed from the main definition but, the document will say, can still be used in settings where ketone testing is unavailable.

As previously, the new statement will classify DKA by mild, moderate, and severe but now for the first time there are recommendations of care for each of those levels, as well as for HHS.

For HHS, the glucose cutoff of ≥ 600 mg/dL will stay the same. But now, the effective serum osmolality has been lowered from > 320 to > 300 mOsml/L to account for the effect of dehydration, along with an alternative criteria of total serum osmolality > 320 mOsm/L. The same two changes as with DKA for both ketones and acidosis have also been included for HHS.

Asked to comment, session audience member and independent diabetes industry consultant Charles Alexander, MD, told this news organization, “I liked the proposal to eliminate the anion gap in decision-making and to focus on measurement of blood ketones, principally beta-hydroxybutyrate, in the diagnosis of DKA and monitoring the effect of treatment.

“If someone is on an SGLT2 inhibitor, there is no need to look at blood glucose levels, which may be normal or near normal in the setting of DKA.”

But Dr. Alexander thinks that they should have eliminated glucose levels entirely as part of the DKA/HHS definition even for people without diabetes.

“The problem is that medical education for many years has taught us that DKA is a condition of high blood glucose, but it may not be. It is good that they said blood glucose levels were not important if the patient had a history of diabetes. However, a glucose of 200mg/dL may not be low enough if someone is on an SGLT2 inhibitor. There needs to be a much lower threshold for measuring blood ketones in anyone with nausea, vomiting, and abdominal pain, regardless of the blood glucose level.”
 

Acute management: IV fluids, insulin, and potassium

Like the 2009 statement, the new one will include detailed management flowcharts for DKA and HHS, but this time in color. This new statement includes individual algorithms for management with intravenous fluids, insulin, and potassium. Bicarbonate has been removed and relegated to a note at the bottom saying that it should only be considered if pH is < 7.0.

Under fluid treatment, the new statement offers more information about using crystalloids to treat dehydration and a recommendation to add dextrose to IV fluid therapy as a substrate when the glucose drops below 250 mg/dL, in order to prevent hypoglycemia. For euglycemic DKA, the recommendation is to include dextrose and normal saline simultaneously.

And for the first time, subcutaneous rather than IV insulin is considered acceptable for mild, but not moderate or severe, DKA. 

Two options are suggested for IV insulin in HHS: The fluid can be given first and low-dose fixed-rate insulin infusion added, or fluids and insulin can be given at the same time.

Criteria for resolution of DKA are a venous pH of ≥ 7.3 or bicarbonate > 18 mmol/L, ketones < 0.6 mmol/L, and glucose ideally < 200 mg/dL (11.0 mmol/L). For HHS, resolution is suggested when the measured or calculated serum osmolality falls to < 300 mosm/kg, blood glucose is < 250mg/dL (13.9 mmol/L), urine output > 0.5 mL/kg/hour, and cognitive status is improved.

The statement also will provide detailed recommended options for transitioning from IV to subcutaneous insulin, but defers to clinical judgment for deciding when the patient can be discharged. The initiation or continuation of SGLT2 inhibitors is not recommended at any time during hospitalization for hyperglycemic crises.
 

Mitigating complications, preventing recurrence

In addition to listing potential complications of treating hyperglycemic crises, just as the 2009 statement did, the new one will offer mitigation strategies for some of the more common ones. For preventing hypoglycemia, frequent blood glucose monitoring is advised along with adding dextrose to the IV fluids when glucose drops below 250 mg/dL.

For prevention of hypokalemia, which occurs in about half of patients treated for DKA and HHS, the statement recommends potassium monitoring every 4 hours and replacement added to fluids.

Acute kidney injury, also occurring in about half of people treated for DKA and/or HHS, usually resolves with hydration. Daily renal function monitoring is advised.
 

Preventing recurrence: Many factors beyond clinical

Prevention of recurrence with readmission for DKA and/or HHS, occurring in up to 22% of U.S. patients within 30 days, entails close follow-up within 2-4 weeks after discharge (including via telemedicine), and assessment of possible causes, including mental health disorders and social determinants of health.

Appropriate education should be provided, including “structured education” involving problem-solving, sick day rules, injection techniques, a review of insulin doses, consideration of continuous glucose monitoring (CGM), and home ketone testing.  

Patients should be provided with an adequate supply of insulin and durable diabetes equipment, along with contact information for health care professionals who can assist them. Social service professionals can be helpful for patients who lack reliable access.

Dr. Gabbay told this news organization, “The eye-opening thing is we tend to typically think of DKA as how people tend to get diagnosed with diabetes and, yes, that’s true, but that’s only a minority of people. Those might be preventable by early screening, but all these other people and the number of recurrent episodes, that’s an area where it’s really a failure of the system where we can do better in ensuring that doesn’t happen.”

Education is only part of it, he stressed. “It’s not just an intelligence thing. It’s social factors, and there can be complex psychological issues and mental health issues. We need to screen for those things when we see someone coming back the second, third, fifth, or sixth time. We’ve all seen that. Just educating them to take their insulin is not the answer. …You’ve got to ask the questions and engage them to go a little deeper.”

Dr. Gabbay is an employee of the ADA. Dr. Alexander has reported being a nonpaid advisor for diaTribe and a consultant for Kinexum. Dr. Misra has received speaker fees from Sanofi and ABCD and an investigator-initiated research grant from Dexcom, and is a trustee for the Diabetes Research and Wellness Foundation in the United Kingdom.

This transcript has been edited for clarity.

The ongoing longitudinal Nurses’ Health Study has served as an incredible database for evaluating disease states prospectively over decades, thanks to the robust input of its participants. Most recently, this allowed for an important analysis of the association between gastroesophageal reflux (GER) symptoms and sleep quality, the results of which were published in JAMA Network Open.

Approximately 49,000 women with a median age of 59 years (range, 48-69 years) provided data for this analysis. Starting in 2005, they were asked about their experience of GER symptoms. In 2017, they were also asked to respond to a questionnaire, a modified Pittsburgh Sleep Quality Index (PSQI). This is a tool we’ve used a lot in prospective studies looking at gastrointestinal diseases and sleep-related abnormalities. It’s unique in that it looks not only at sleep but also at next-day function and daytime sleepiness, which is important here for its implications related to reflux disease and sleep fragmentation.

In assessing these outcomes, the investigators found that the relative risk for association with sleep fragmentation was approximately 15% greater in those with GER symptoms occurring one to three times a month. For those with GER symptoms occurring once a week and more than once a week, the approximate relative risk increased by 30% and 53%, respectively. Clearly, the association of GER symptoms and relative sleep quality was really important.

It should be noted that the PSQI is a disease-independent, validated instrument. It’s not specific to GER disease or any diseases. It’s cross validated across 17 different languages. I think what’s most important about its use in the assessment here is the incorporation of next-day function and asking participants about daytime sleepiness, which we’ll discuss in more detail shortly.
 

The many causes of interrupted sleep

We’ve all experienced sleep fragmentation, whether in the form of having been on call during our medical training or common experiences like hearing a child cry in the night, a noisy truck pass by, or a dog barking. You may or may not remember that these happened the next day, but they’ve nonetheless interrupted your sleep efficiency.

When you transition laterally across the stages of sleep, that’s what establishes the circadian rhythm and ensures sleep hygiene. Typically, we require approximately 7 hours of restful sleep to do that. But if you fragment or interrupt this process, you more or less move your way erratically through the night, disrupting sleep hygiene and efficiency.

If you have a cognitive awakening during those disruptions, you may recall those events the next day. Or, you may not remember it at all, and such amnestic events are normal for some people with sleep disruptions.

You may also have a sensory arousal, whether it’s due to GER symptoms, auditory stimuli, bumping your toe, or whatever disruptive event. Any of these can cause you to lose that laterality of smooth transition through sleep.

Approximately 20% of the U.S. population have reported GER symptoms at least once a week. Incident data indicate that number may be increasing by as much as 5% a year. Much of that increase is tied to obesity. But nonetheless, it’s a problem on the rise.

It’s important to know this as we start to look at sleep. If GER is acting as a trigger to sleep disruption, you need to ask your patients with this condition about next-day function.

In particular, the next-day function questions to ask are, “How do you feel when you get up? Are you awake and refreshed? Do you have early fatigue? Do you drag yourself out of bed, have daytime somnolence, loss of concentration, or irritability?”

Those are key parameters we can use for looking back to the night before and gauging sleep efficiency. If you’re not asking those questions, you may miss out on identifying a patient having sleep fragmentation.
 

Sleep’s role in inflammatory disease processes

I now perform an interval assessment of this type not just in my patients with GER disease but across all my patients. I do so because sleep is physiologically important in so many ways.

In patients who have nonalcoholic fatty liver disease and a variety of other liver diseases, we’re finding an increased association with sleep fragmentation outside of sleep apnea.

The same is true with irritable bowel and other functional diseases.

When you have sleep fragmentation in inflammatory bowel disease, you turn on a variety of inflammatory proteins (e.g., C-reactive protein) and cytokines, such as interleukins and tumor necrosis factor alpha. These processes may actually tip somebody over to a pro-inflammatory state.

When it comes to what might be considered a relatively simpler condition like GER disease, Ronnie Fass and colleagues showed a number of years ago via Bernstein testing performed in patients with both fragmented and normal sleep that the sensory thresholds all get lowered in the former group. This is irrespective of whether you have a functional symptom or you’re awakened by bumping your toe, a headache, or having heartburn; your sensory thresholds are lower. As a result, the same stimulus provides a higher sense of awareness. By ramping up that awareness, you increase the interference with the next-day function.

We’ve shown that sleep fragmentation affects a variety of things, including immune function. This may be why many people get sick when they travel in between time zones.

There are also implications relating to things like obesity. When you have sleep dysfunction, you have effects on leptin and ghrelin, contrary to what you would normally want to have. This, in turn, causes adverse effects on stimulation or suppression of satiety or appetite. These are things that I counsel my patients about when I talk about reflux as well as those trying to lose weight.

This latest analysis from the Nurses’ Health Study reminds us that a lot of people have reflux and a lot of people have sleep fragmentation. We need to do better in asking our patients if they have symptoms specific not only to reflux but also to potentially sleep-related complications.

The more we do that, the more we individualize patient treatment rather than treating them as a disease state. This, in turn, will allow us to practice personalized medicine. The more we can engage our patients with reflux disease by asking the right questions about next-day function, the better we can do in improving their outcomes.

It’s time for us all to open our eyes to the value of closing them. Let’s talk to our patients with reflux disease in a little bit of a different light, providing a new perspective on strategies we can use to mitigate and deal with those symptoms, thereby preventing the consequences of sleep fragmentation.

Hopefully, this overview gives you some guidance the next time you have a conversation with your patients. It will apply across many, many disease states, and in almost everything we do in gastroenterology.

The ongoing longitudinal Nurses’ Health Study has served as an incredible database for evaluating disease states prospectively over decades, thanks to the robust input of its participants. Most recently, this allowed for an important analysis of the association between gastroesophageal reflux (GER) symptoms and sleep quality, the results of which were published in JAMA Network Open.

Approximately 49,000 women with a median age of 59 years (range, 48-69 years) provided data for this analysis. Starting in 2005, they were asked about their experience of GER symptoms. In 2017, they were also asked to respond to a questionnaire, a modified Pittsburgh Sleep Quality Index (PSQI). This is a tool we’ve used a lot in prospective studies looking at gastrointestinal diseases and sleep-related abnormalities. It’s unique in that it looks not only at sleep but also at next-day function and daytime sleepiness, which is important here for its implications related to reflux disease and sleep fragmentation.

In assessing these outcomes, the investigators found that the relative risk for association with sleep fragmentation was approximately 15% greater in those with GER symptoms occurring one to three times a month. For those with GER symptoms occurring once a week and more than once a week, the approximate relative risk increased by 30% and 53%, respectively. Clearly, the association of GER symptoms and relative sleep quality was really important.

It should be noted that the PSQI is a disease-independent, validated instrument. It’s not specific to GER disease or any diseases. It’s cross validated across 17 different languages. I think what’s most important about its use in the assessment here is the incorporation of next-day function and asking participants about daytime sleepiness, which we’ll discuss in more detail shortly.
 

The many causes of interrupted sleep

We’ve all experienced sleep fragmentation, whether in the form of having been on call during our medical training or common experiences like hearing a child cry in the night, a noisy truck pass by, or a dog barking. You may or may not remember that these happened the next day, but they’ve nonetheless interrupted your sleep efficiency.

When you transition laterally across the stages of sleep, that’s what establishes the circadian rhythm and ensures sleep hygiene. Typically, we require approximately 7 hours of restful sleep to do that. But if you fragment or interrupt this process, you more or less move your way erratically through the night, disrupting sleep hygiene and efficiency.

If you have a cognitive awakening during those disruptions, you may recall those events the next day. Or, you may not remember it at all, and such amnestic events are normal for some people with sleep disruptions.

You may also have a sensory arousal, whether it’s due to GER symptoms, auditory stimuli, bumping your toe, or whatever disruptive event. Any of these can cause you to lose that laterality of smooth transition through sleep.

Approximately 20% of the U.S. population have reported GER symptoms at least once a week. Incident data indicate that number may be increasing by as much as 5% a year. Much of that increase is tied to obesity. But nonetheless, it’s a problem on the rise.

It’s important to know this as we start to look at sleep. If GER is acting as a trigger to sleep disruption, you need to ask your patients with this condition about next-day function.

In particular, the next-day function questions to ask are, “How do you feel when you get up? Are you awake and refreshed? Do you have early fatigue? Do you drag yourself out of bed, have daytime somnolence, loss of concentration, or irritability?”

Those are key parameters we can use for looking back to the night before and gauging sleep efficiency. If you’re not asking those questions, you may miss out on identifying a patient having sleep fragmentation.
 

Sleep’s role in inflammatory disease processes

I now perform an interval assessment of this type not just in my patients with GER disease but across all my patients. I do so because sleep is physiologically important in so many ways.

In patients who have nonalcoholic fatty liver disease and a variety of other liver diseases, we’re finding an increased association with sleep fragmentation outside of sleep apnea.

The same is true with irritable bowel and other functional diseases.

When you have sleep fragmentation in inflammatory bowel disease, you turn on a variety of inflammatory proteins (e.g., C-reactive protein) and cytokines, such as interleukins and tumor necrosis factor alpha. These processes may actually tip somebody over to a pro-inflammatory state.

When it comes to what might be considered a relatively simpler condition like GER disease, Ronnie Fass and colleagues showed a number of years ago via Bernstein testing performed in patients with both fragmented and normal sleep that the sensory thresholds all get lowered in the former group. This is irrespective of whether you have a functional symptom or you’re awakened by bumping your toe, a headache, or having heartburn; your sensory thresholds are lower. As a result, the same stimulus provides a higher sense of awareness. By ramping up that awareness, you increase the interference with the next-day function.

We’ve shown that sleep fragmentation affects a variety of things, including immune function. This may be why many people get sick when they travel in between time zones.

There are also implications relating to things like obesity. When you have sleep dysfunction, you have effects on leptin and ghrelin, contrary to what you would normally want to have. This, in turn, causes adverse effects on stimulation or suppression of satiety or appetite. These are things that I counsel my patients about when I talk about reflux as well as those trying to lose weight.

Sleep disruption affects cortisol stimulation and has a significant correlation with type 2 diabetes, cardiovascular diseases, and even mortality statistics.

Nirmatrelvir-ritonavir (Paxlovid) is associated with a reduced risk for death or hospitalization in the most extremely vulnerable patients with COVID-19, new research suggests.

In a cohort study from British Columbia that included nearly 7,000 patients with COVID-19, nirmatrelvir-ritonavir was associated with a 2.5% reduction in risk for death or emergency hospitalization in clinically extremely vulnerable (CEV) patients who were severely immunocompromised. No significant benefit was observed in patients who were not immunocompromised.

“This finding could help substantially limit unnecessary use of nirmatrelvir and ritonavir in older, otherwise healthy individuals,” lead author Colin R. Dormuth, ScD, associate professor of anesthesiology, pharmacology, and therapeutics at the University of British Columbia, Vancouver, told this news organization. “Another finding that was surprising and might help place the role of nirmatrelvir and ritonavir in context is that even in severely immunocompromised individuals who did not take [the drug], the risk of death or hospitalization with COVID-19 was less than 4% in our study population.”

The study was published online in JAMA Network Open.
 

Who benefits?

The investigators analyzed medical records for 6,866 patients in British Columbia (median age, 70 years; 57% women) who presented between Feb. 1, 2022, and Feb. 3, 2023. Eligible patients belonged to one of four higher-risk groups who received priority for COVID-19 vaccination.

Two groups included CEV patients who were severely (CEV1) or moderately (CEV2) immunocompromised. The CEV3 group was not immunocompromised but had medical conditions associated with a high risk for complications from COVID-19. A fourth expanded eligibility (EXEL) group included higher-risk patients who were not in one of the other groups, such as unvaccinated patients older than age 70 years.

The investigators matched treated patients to untreated patients in the same vulnerability group according to age, sex, and month of infection. The primary outcome was death from any cause or emergency hospitalization with COVID-19 within 28 days.

Treatment with nirmatrelvir-ritonavir was associated with statistically significant relative reductions in the primary outcome, compared with no treatment, for patients in the CEV1 (risk difference, −2.5%) and CEV2 (RD, −1.7%) groups. In the CEV3 group, the RD of −1.3% was not statistically significant. In the EXEL group, treatment was associated with a higher risk for the primary outcome (RD, 1.0%), but the result was not statistically significant.

The results were “robust across sex and older vs. younger age,” the authors note. “No reduction in the primary outcome was observed in lower-risk individuals, including those aged 70 years or older without serious comorbidities.”

The combination of nirmatrelvir-ritonavir was approved for use in Canada based on interim efficacy and safety data from the Evaluation of Inhibition for COVID-19 in High-Risk Patients (EPIC-HR) trial, said Dr. Dormuth.

British Columbia’s eligibility criteria for nirmatrelvir-ritonavir coverage differ substantially from the criteria for participants in the EPIC-HR trial, he noted. Those patients were unvaccinated, had no natural immunity from a previous COVID-19 infection, and were infected with COVID-19 variants that were different from those now circulating. The current study was prompted by the need to look at a broader population of individuals in British Columbia with varying risks of complications from COVID-19 infection.

Before the study, a common view was that patients aged 70 and older would benefit from the drug, said Dr. Dormuth. “Our study, which accounted for medical conditions related to an individual’s vulnerability to complications, showed that older age on its own was not a reason to use nirmatrelvir and ritonavir once relevant medical conditions were taken into consideration.”

The researchers are working on a study to identify with greater specificity which comorbid conditions are most associated with nirmatrelvir-ritonavir effectiveness, he added. “It could be that a relatively small number of conditions can be used to identify most individuals who would benefit from the drug.”
 

‘Signal toward benefit’

Commenting on the findings for this news organization, Abhijit Duggal, MD, vice chair of critical care at the Cleveland Clinic, who was not involved in this study, said, “I’m always very wary when we look at observational data and we start saying the effectiveness is not really as high as was seen in other studies. We are seeing an effect with all these studies that seems to be in the right direction.

“Having said that,” he added, “is the effect going to be potentially more in patients at higher risk? Absolutely. I think these postmarket studies are really showing that after vaccination, if someone does get infected, this is a secondary option available to us that can prevent progression of the disease, which would likely be more severe in immunocompromised patients.”

Dr. Duggal was a coinvestigator on a recent study of more than 68,000 patients that showed that nirmatrelvir-ritonavir or molnupiravir was associated with reductions in mortality and hospitalization in nonhospitalized patients infected with the Omicron variant, regardless of age, race and ethnicity, virus strain, vaccination status, previous infection status, or coexisting conditions.

“In all groups, there was a signal toward benefit,” said Dr. Duggal. “These studies tell us that these drugs do remain valid options. But their use needs to be discussed on a case-by-case basis with patients we feel are deteriorating or at a higher risk because of underlying disease processes.”

The study was supported by funding from the British Columbia Ministry of Health. Dr. Dormuth and Dr. Duggal report no relevant financial relationships.

A shave biopsy revealed acanthosis, papillomatosis, hyperkeratosis, hypergranulosis, parakeratosis, and cytoplasmic viral-like inclusions without atypia, consistent with a diagnosis of a common wart. The biopsy ruled out other possible diagnoses, which included keratoacanthoma, seborrheic keratosis, and squamous cell carcinoma.

Cutaneous warts can manifest as common warts (verruca vulgaris), plantar warts (verruca plantaris), or plane warts (verruca plana). These benign skin lesions are caused by human papillomavirus and can manifest in areas of skin trauma; this is known as the Koebner phenomenon. Most warts can be diagnosed through clinical history and examination. Dermoscopy, if performed, may reveal thrombosed capillaries as dotted structures, but there is an increased risk of cross-contamination.¹ That said, some dermatoscopes have disposable covers or can be cleaned with antiviral, antibacterial wipes. If the diagnosis is unclear or the exam is clinically suspicious, a biopsy may be required.

Cases with progressive enlargement and extensive involvement of the skin (as was seen here) are generally associated with certain predisposing conditions, such as atopic dermatitis and immunosuppression.² Our patient screened negative for HIV infection, and further evaluation did not reveal any concerns for immunosuppression.

Treatment for a common wart depends on patient characteristics, preferences, cost, and possible adverse effects. Standard treatment options are topical salicylic acid and cryotherapy with liquid nitrogen. Depending on the location and type of the wart, multiple treatments may be required, and recurrences are common. Intralesional injection with bleomycin, 5‐fluorouracil, or cidofovir is often used for recurrent and refractory warts.

Patients unable to tolerate cryotherapy or local injections may benefit from thermotherapy by heating the wart with a pulsed dye laser.³ Observation is also a reasonable course of action for new warts, as they may spontaneously resolve within a year.

In this case, the patient opted for over-the-counter salicylic acid 17% to be applied nightly until resolution. Cryosurgery would be a next step for him if the lesion does not resolve after 3 months of treatment.

A shave biopsy revealed acanthosis, papillomatosis, hyperkeratosis, hypergranulosis, parakeratosis, and cytoplasmic viral-like inclusions without atypia, consistent with a diagnosis of a common wart. The biopsy ruled out other possible diagnoses, which included keratoacanthoma, seborrheic keratosis, and squamous cell carcinoma.

Cutaneous warts can manifest as common warts (verruca vulgaris), plantar warts (verruca plantaris), or plane warts (verruca plana). These benign skin lesions are caused by human papillomavirus and can manifest in areas of skin trauma; this is known as the Koebner phenomenon. Most warts can be diagnosed through clinical history and examination. Dermoscopy, if performed, may reveal thrombosed capillaries as dotted structures, but there is an increased risk of cross-contamination.¹ That said, some dermatoscopes have disposable covers or can be cleaned with antiviral, antibacterial wipes.

Michelle L. O’Donoghue, MD, MPH: I’m here in Amsterdam at the European Society of Cardiology (ESC) Congress 2023. Joining me for a great discussion is my friend Dr. Pam Taub, who is a cardiologist and a professor of medicine at UC San Diego. She has a particular interest in postural orthostatic tachycardia syndrome (POTS), so that’s what we’ll be talking about today.

Thanks for joining me, Pam. When we think about POTS, for those who are not familiar with the term, what does it actually mean and how do you diagnose it?
 

No tilt table required

Pam R. Taub, MD: As you said, it’s postural orthostatic tachycardia syndrome. What that means is when somebody stands up, they have an elevation in their heart rate that is usually 30 points from when they’re lying down. That’s typically associated with symptoms such as lightheadedness, dizziness, and cognitive difficulties such as brain fog. The diagnosis can be made by tilt-table testing, but it can also be made in the office with simple orthostats.

In my clinic, I have people lie down for 3-5 minutes. At the end of that period, you get a heart rate and blood pressure. Then you have them stand up for 3-5 minutes and then get heart rate and blood pressure, and you look at the differences. If the heart rate goes up by 30 points – so maybe they’re 80 beats/min when they’re lying down and when they stand up, it goes to 110 beats/min  – that’s POTS, so very objective criteria. Typically, these people don’t have what we call orthostatic hypotension, where there is a significant decrease in the blood pressure. It’s more a heart rate issue.

Dr. O’Donoghue: How symptomatically do they usually present?

Dr. Taub: It’s a spectrum. Some people have mild symptoms. After they’re in the upright position for maybe 10 minutes, they get symptoms. There are some people who, when they go from a lying to standing position, they’re extremely symptomatic and can’t really do any activities. There are some people that are even wheelchair-bound because the symptoms are so debilitating. There’s a wide spectrum.

Dr. O’Donoghue: There has been more discussion, I feel like, about the rising prevalence of POTS as a diagnosis, and in particular since the COVID pandemic. What’s our understanding of the relationship between COVID and POTS and what the mechanism might be?

Dr. Taub: We’ve known that POTS can be triggered by a viral infection. Before COVID, we knew that in certain individuals that we think have an underlying genetic predisposition, usually some autoimmune substrate, when they get certain types of infections, whether it’s influenza or mononucleosis, they get POTS.

Typically, when they get an infection, they start getting deconditioned. They don’t feel well, so they’re on bed rest. When they get long periods of bed rest, when they start to become active, they start to have overactivation of their sympathetic nervous system, and they have a large amount of cardiovascular deconditioning. It’s a cycle that is often triggered after an infection.

A huge increase of POTS has been seen after COVID-19 because we had so many people exposed to this virus. With COVID-19, there is a period where people don’t feel great and they are getting bed rest, so they’re getting deconditioned. We’ve seen so many patients referred for post-COVID POTS and also long COVID or the post-acute sequelae of COVID-19, where POTS is a part of that presentation.

Female sex and autoimmune conditions

Dr. O’Donoghue: We know that POTS seems to disproportionately affect women. Is that understood? Is it thought that that’s related to the perhaps the autoimmune component of that illness?

Dr. Taub: Yes. The theory is because women tend to have more autoimmune conditions, that’s why they’re more predisposed. There’s a large amount of genetic susceptibility. For instance, we know that there’s an association between POTS and conditions like Ehlers-Danlos syndrome and between POTS and mast cell activation. Some of those conditions are more prevalent in women as well.

Dr. O’Donoghue: I feel like many physicians don’t know how to manage POTS, and they’re actually a little fearful perhaps to take it on. Fortunately, there have been a growing number of POTS clinics with specialists that focus on that area. For the average practitioner who maybe can’t refer to a POTS clinic, how should they approach that?

Dr. Taub: The first thing is its diagnosis. When someone tells you that they have symptoms of orthostatic intolerance – so, activities that involve standing – you need to first have that on your differential diagnosis. You can make the diagnosis in the office with orthostats. You don’t need a tilt table. It’s sometimes helpful if you’re unsure about the diagnosis, but you can make the diagnosis.

Many times, you’re finding people that have very mild symptoms. You can treat that with some good lifestyle recommendations, such as increased hydration, increasing salt in their diet, and compression. And the exercise component is really important.

Many people with POTS are told to go exercise, go for a run, or go for a walk. That’s incorrect, because these people have symptoms when they’re in the upright position. The type of exercise they need to do initially is exercise in the lying or seated position – so exercises like rowing or a seated bike, and strength training. As they start to feel better, then they can do upright exercise.

You should never tell a person that has POTS to just initially start with upright exercise, because they’re going to feel so much worse and then they’re never going to want to exercise. It’s really important to give them the right exercise recommendations. I find that for many of these mild cases, if they do the right exercise and engage in the right lifestyle strategies, they get better.

Compression wear and drug therapy

Dr. O’Donoghue: When it comes to compression stockings, do you usually start with a particular length?

Dr. Taub: It’s interesting. There are many different compression stockings, medical grade. Through patients with POTS, I’ve gotten feedback on certain types of athletic wear that have built-in compression, and that’s a little bit easier for people to wear every day because they can do their errands and it doesn’t look like they’re wearing medical-grade compression stockings.

Basically, I’ve collected all the different recommendations that patients say help, and I give them a list. The medical-grade compression stockings sometimes are very challenging to put on, and sometimes people just need light compression or even just socks. Any kind of compression is going to help.

Dr. O’Donoghue: That’s a great tip, because I know there are many patients who refuse to wear the compression stockings. If there’s a fashionable alternative, that’s always good to reach for.

Dr. Taub: Another thing that patients have told me is that abdominal compression is also very helpful. There are many commercially available abdominal compression options, like shapewear. Many patients with POTS use that and that helps, too.

Dr. O’Donoghue: Good. For those patients with POTS that is refractory to the measures you’ve already discussed, what are the next steps after that?

Dr. Taub: Pharmacotherapy is very synergistic with lifestyle, and there are many different pharmacotherapy options. One of the first things that you want to think about is lowering that heart rate. The reason people feel horrible is because their heart rate is usually very high when they’re upright. If they’re upright for long periods of time and they’re having very high heart rates, they’re going to get really tired because it’s like they’re exercising for hours when they’re upright.

Heart rate lowering is the cornerstone of therapy. Traditionally, we’ve used beta-blockers for heart rate lowering. The problem is they also lower blood pressure. They can also cause fatigue, so not the ideal agent for patients with POTS.

One of the clinical trials that I led was with a drug called ivabradine, which selectively works on the SA node and decreases heart rate without affecting blood pressure. What’s really elegant about ivabradine is it has a more potent effect when the heart rate is higher. When the patient is standing, it’s going to have a more potent effect on heart rate lowering. It’s really well tolerated in patients with POTS. In our study, we showed an improvement in quality of life metrics. That’s one of the first-line drugs that I use for patients with POTS.

The other thing is some of them will also have a concomitant lowering of blood pressure. You can think about medications that increase blood pressure, like midodrine, fludrocortisone, and droxidopa. Sometimes that combination of a heart rate-lowering medication and a medication that increases blood pressure really works well.

Dr. O’Donoghue: That’s very helpful. I think that those kinds of practical tips are the ones that practitioners really want to reach for, because they need to have that algorithm in their mind to take on this condition. Thanks again for walking us through that.

I think it’s a very interesting space, and there’s more that we’re going to be learning over the next few years as we further flesh out these post-COVID cases and what we learn from that as well.

Dr. Taub: There are many clinical trials now starting in POTS, so it’s exciting.

Dr. O’Donoghue: Absolutely. Thank you again for joining me today. Signing off, this is Dr Michelle O’Donoghue.

The widening threat of the animal tranquilizer xylazine, otherwise known as tranq, which has been found in illegally manufactured fentanyl, necessitates wider testing, a better understanding of its effects, and more research on treatment options, according to a narrative review published in the Annals of Internal Medicine.

“A lot of doctors and providers are asking about this drug,” said Joseph D’Orazio, MD, an addiction medicine specialist and medical toxicologist at Cooper University Healthcare, Camden, N.J., who led the review.

Xylazine is believed to prolong or intensify the effects of opioids, making it a popular additive to illegally produced opioids, particularly fentanyl, according to the Drug Enforcement Administration. Users end up in a zombie-like state with slowed breathing, and they sometimes develop skin ulcers. Because xylazine is not an opioid, common antidotes such as naloxone are ineffective. The White House has called the fentanyl-xylazine combo an “emerging threat.”

“Xylazine is making the deadliest drug threat our country has ever faced, fentanyl, even deadlier,” said DEA administrator Anne Milgram, in a statement on the agency’s website. “DEA has seized xylazine and fentanyl mixtures in 48 of 50 States. The DEA Laboratory System is reporting that in 2022 approximately 23% of fentanyl powder and 7% of fentanyl pills seized by the DEA contained xylazine.”

Dr. D’Orazio paired clinical experience with available research to provide guidance on the care of patients exposed to xylazine.

He and his team issued a call for more research on the drug’s effects, including more details on dependency and withdrawal.

Testing a patient who may have been exposed to xylazine requires forensic lab capabilities, which makes testing complicated and costly. The review found no evidence of the origin of the drug or why it causes open sores.

The review calls for more education of providers, including primary care physicians, on the treatment and care of patients who have used xylazine and fentanyl. The authors also call for expanding standard urine analysis to test for xylazine and for intensifying surveillance of the drug supply and distribution of xylazine test strips.

The authors of an editorial that accompanied the journal article urged the health care community to get ahead of xylazine before the crisis worsens.

“Not testing for xylazine in current unaffected areas and populations may lead to delays in responding if and when the drug becomes prevalent in the drug supply,” the authors wrote.

Xylazine was detected in 90% of street opioid samples tested in Philadelphia in 2021, and a toxic surveillance study of drug paraphernalia in Maryland found xylazine in 80% of samples tested between 2021 and 2022.

Dr. D’Orazio stressed that although Narcan is ineffective in treating xylazine, because the sedative is almost always mixed with fentanyl or another opiate, the opioid antagonist should still be used in emergencies.

Angelique Campen, MD, an emergency medicine physician at Providence St. Joseph Medical Center, Burbank, Calif., said she has seen an increase in patients entering the emergency department under the influence of what seems like fentanyl or heroin, but standard treatments such as Narcan have a limited effect. These patients remain in a prolonged period of sedation.

Recently, she admitted to her hospital’s intensive care unit a patient suspected of a xylazine overdose who was not responding to treatment.

Dr. Campen said that patients are screened for fentanyl, but because no test is available for xylazine, she presumed xylazine was causing the complication.

“It makes perfect medical sense to me that that’s what was going on,” Dr. Campen, who has worked at St. Joseph’s for 25 years, said. “I’m hoping with physicians being more aware of it that we can have that part of our regular urine drug screen.”

Dr. Campen also said she hopes an antidote is soon developed.

“If we can just keep delivering that message, hopefully, [to] more and more people, it will get through to them,” she said. “Every time you’re taking this, even though you may have taken it a week before and been fine, you never know: The next dose you take may be the lethal dose.”

Another author reports receiving payments for training conducted as part of a NJDMAHS training grant to educate on substance use disorders.

TOPLINE:

Metabolic dysfunction–associated steatotic liver disease (MASLD) significantly raises the risk for cardiovascular, metabolic, oncologic, and other outcomes, a new meta-analysis suggests.

METHODOLOGY:

• Researchers conducted a comprehensive meta-analysis of studies to investigate longitudinal clinical outcomes associated with MASLD, previously known as nonalcoholic fatty liver disease.
• They identified 129 original studies that evaluated the longitudinal risks for incident clinical outcomes in patients with MASLD vs those without the disease.
• Investigators calculated pooled risk estimates for clinical outcomes in patients with MASLD and those without MASLD, with MASLD being diagnosed by imaging, biopsy, blood tests, or ICD codes.

TAKEAWAY:

• MASLD was associated with a significant increased risk for cardiovascular disease outcomes (hazard ratio, 1.43), metabolic outcomes such as incident hypertension (HR, 1.75), prediabetes (HR, 1.69), diabetes (HR, 2.56), metabolic syndrome (HR, 2.57), chronic kidney disease (HR, 1.38), and various liver-related outcomes (HR, 3.92).
• Patients with advanced MASLD had a significantly greater risk (P = .02) of developing diabetes than did their peers with less severe MASLD (HR, 1.63), compared with persons without MASLD.
• MASLD was also associated with all cancers (HR, 1.54); the highest risk was seen for hepatocellular carcinoma (HR, 4.37).
• Subgroup analyses stratified by sex found no significant differences in the risks observed between men and women with MASLD.

IN PRACTICE:

“It is imperative to understand that MASLD is a complex and multifaceted condition that requires a comprehensive approach to recognition and treatment beyond that of the hepatologist alone,” the authors wrote. “The growing prevalence of MASLD will remain a major global health threat that requires effective disease management frameworks to be put in place.”

SOURCE:

The study, with co–first authors Kai En Chan and Elden Yen Hng Ong, National University of Singapore, was published online in Clinical Gastroenterology and Hepatology.

LIMITATIONS:

The results depend on the validity of the original studies, and residual confounding factors may have biased the reported results. The study is also limited in its inclusion of large population-based studies using ICD codes that may result in misclassification bias. There was no examination of longitudinal outcomes in patients with histologically confirmed MASLD.

DISCLOSURES:

The study had no funding. Some authors reported research support, consulting fees, or stock options from pharmaceutical companies.

TOPLINE:

Compared with supervised treadmill workouts at a gym, which is considered first-line therapy for walking impairment in lower extremity peripheral artery disease (PAD), exercising at home significantly improves 6-minute walking (6MW) distance, but not maximal treadmill walking distance, results of a new meta-analysis show.

METHODOLOGY:

• The analysis included five randomized clinical trials with a total of 719 participants, mean age 68.6 years, all led by researchers at Northwestern University, Chicago, that compared either supervised treadmill or home-based walking exercise with a nonexercise control group in people with PAD (defined as Ankle Brachial Index ≤ 0.90).
• All trials measured 6-minute walk (6MW) distance (walking as far as possible in 6 minutes), treadmill walking performance, and outcomes from the Walking Impairment Questionnaire (WIQ), which includes distance, walking speed, and stair-climbing domains, at baseline and at 6 months.
• Supervised treadmill exercise interventions included three individualized exercise sessions per week with an exercise physiologist at an exercise center, and home-based exercises involved walking near home 5 days per week, both for up to 50 minutes per session.

TAKEAWAY:

• After adjusting for study, age, sex, race, smoking, history of myocardial infarction, heart failure, and baseline 6MW distance, the study found both exercise interventions were better than nonexercise controls for 6MW distance.
• Compared with supervised treadmill exercise, home-based walking was associated with significantly improved mean 6MW distance (31.8 m vs. 55.6 m; adjusted between-group difference: −23.8 m; 95% confidence interval, −44.0 to −3.6; P = .021), and significantly improved WIQ walking speed score.
• However, home-based walking was associated with significantly less improvement in maximal treadmill walking distance, compared with supervised treadmill exercise (adjusted between-group difference: 132.5 m; 95% CI, 72.1-192.9; P < .001).

IN PRACTICE:

Home-based walking exercise “circumvents” barriers to accessing supervised exercise such as having to travel to a facility, said the authors, who noted the new data “demonstrated a large and consistent effect of home-based walking exercise on improved 6MW distance and also significantly improved the WIQ walking speed score, compared with supervised treadmill exercise.”

SOURCE:

The study was conducted by Neela D. Thangada, MD, Northwestern University, Chicago, and colleagues. It was published online in JAMA Network Open.

LIMITATIONS:

Data were combined from different randomized clinical trials that were led by one investigative team, and reported comparisons were not prespecified. Comparisons between supervised and home-based exercise lacked statistical power for the WIQ distance and stair-climbing measures.

DISCLOSURES:

The study was sponsored by the National Center for Research Resources and the National Heart, Lung, and Blood Institute of the National Institutes of Health. Dr. Thangada reports no relevant financial relationships. Disclosures for study coauthors can be found with the original article.

Thyroxine and L-thyroxine are two of the 10 most frequently prescribed medicinal products. “One large health insurance company ranks thyroid hormone at fourth place in the list of most-sold medications in the United States. It is possibly the second most commonly prescribed preparation,” said Joachim Feldkamp, MD, PhD, director of the University Clinic for General Internal Medicine, Endocrinology, Diabetology, and Infectious Diseases at Central Hospital, Bielefeld, Germany, at the online press conference for the German Society of Endocrinology’s hormone week.

The preparation is prescribed when the thyroid gland produces too little thyroid hormone. The messenger substance thyroid-stimulating hormone (TSH) is used as a screening value to assess thyroid function. An increase in TSH can indicate that too little thyroid hormone is being produced.

“But this does not mean that an underactive thyroid gland is hiding behind every elevated TSH value,” said Dr. Feldkamp. Normally, the TSH value lies between 0.3 and 4.2 mU/L. “Hypothyroidism, as it’s known, is formally present if the TSH value lies above the upper limit of 4.2 mU/L,” said Dr. Feldkamp.
 

Check again

However, not every elevated TSH value needs to be treated immediately. “From large-scale investigations, we know that TSH values are subject to fluctuations,” said Dr. Feldkamp. Individual measurements must therefore be taken with a grain of salt and almost never justify a therapeutic decision. Therefore, a slightly elevated TSH value should be checked again 2-6 months later, and the patient should be asked if they are experiencing any symptoms. “In 50%-60% of cases, the TSH value normalized at the second checkup without requiring any treatment,” Dr. Feldkamp explained.

The TSH value could be elevated for several reasons:

• Fluctuations depending on the time of day. At night and early in the morning, the TSH value is much higher than in the afternoon. An acute lack of sleep can lead to higher TSH values in the morning.
• Fluctuations depending on the time of year. In winter, TSH values are slightly higher than in the summer owing to adaptation to cooler temperatures. Researchers in the Arctic, for example, have significantly higher TSH values than people who live in warmer regions.
• Age-dependent differences. Children and adolescents have higher TSH values than adults do. The TSH values of adolescents cannot be based on those of adults because this would lead to incorrect treatment. In addition, TSH values increase with age, and slightly elevated values are initially no cause for treatment in people aged 70-80 years. Caution is advised during treatment, because overtreatment can lead to cardiac arrhythmias and a decrease in bone density.
• Sex-specific differences. The TSH values of women are generally a little higher than those in men.
• Obesity. In obesity, TSH increases and often exceeds the normal values usually recorded in persons of normal weight. The elevated values do not reflect a state of hypofunction but rather the body’s adjustment mechanism. If these patients lose weight, the TSH values will drop spontaneously. Slightly elevated TSH values in obese people should not be treated with thyroid hormones.

The nutritional supplement biotin (vitamin H or vitamin B7), which is often taken for skin, hair, and nail growth disorders, can distort measured values. In many of the laboratory methods used, the biotin competes with the test substances used. As a result, it can lead to falsely high and falsely low TSH values. At high doses of biotin (for example, 10 mg), there should be at least a 3-day pause (and ideally a pause of 1 week) before measuring TSH.
 

Hasty prescriptions

“Sometimes, because of the assumption that every high TSH value is due to sickness-related hypothyroidism, thyroid hormones can be prescribed too quickly,” said Dr. Feldkamp. This is also true for patients with thyroid nodules due to iodine deficiency, who are often still treated with thyroid hormones.

“These days, because we are generally an iodine-deficient nation, iodine would potentially be given in combination with thyroid hormones but not with thyroid hormones alone. There are lots of patients who have been taking thyroid hormones for 30 or 40 years due to thyroid nodules. That should definitely be reviewed,” said Dr. Feldkamp.
 

When to treat?

Dr. Feldkamp does not believe that standard determination of the TSH value is sensible and advises that clinicians examine patients with newly occurring symptoms, such as excess weight, impaired weight regulation despite reduced appetite, depression, or a high need for sleep.

If there are symptoms, the thyroid function must be clarified further. “This includes determination of free thyroid hormones T3 and T4; detection of antibodies against autologous thyroid tissue such as TPO-Ab [antibody against thyroid peroxidase], TG-Ab [antibody against thyroglobulin], and TRAb [antibody against TSH receptor]; and ultrasound examination of the metabolic organ,” said Dr. Feldkamp. Autoimmune-related hypothyroidism (Hashimoto’s thyroiditis) is the most common cause of an overly high TSH level.

Treatment should take place in the following situations:

• In young patients with TSH values greater than 10 mU/L;
• In young (< 65 years) symptomatic patients with TSH values of 4 to less than 10 mU/L;
• With elevated TSH values that result from thyroid surgery or radioactive iodine therapy;
• In patients with a diffuse enlarged or severely nodular thyroid gland
• In pregnant women with elevated TSH values.

Thyroxine and L-thyroxine are two of the 10 most frequently prescribed medicinal products. “One large health insurance company ranks thyroid hormone at fourth place in the list of most-sold medications in the United States. It is possibly the second most commonly prescribed preparation,” said Joachim Feldkamp, MD, PhD, director of the University Clinic for General Internal Medicine, Endocrinology, Diabetology, and Infectious Diseases at Central Hospital, Bielefeld, Germany, at the online press conference for the German Society of Endocrinology’s hormone week.

The preparation is prescribed when the thyroid gland produces too little thyroid hormone. The messenger substance thyroid-stimulating hormone (TSH) is used as a screening value to assess thyroid function. An increase in TSH can indicate that too little thyroid hormone is being produced.

“But this does not mean that an underactive thyroid gland is hiding behind every elevated TSH value,” said Dr. Feldkamp. Normally, the TSH value lies between 0.3 and 4.2 mU/L. “Hypothyroidism, as it’s known, is formally present if the TSH value lies above the upper limit of 4.2 mU/L,” said Dr. Feldkamp.
 

Check again

However, not every elevated TSH value needs to be treated immediately. “From large-scale investigations, we know that TSH values are subject to fluctuations,” said Dr. Feldkamp. Individual measurements must therefore be taken with a grain of salt and almost never justify a therapeutic decision. Therefore, a slightly elevated TSH value should be checked again 2-6 months later, and the patient should be asked if they are experiencing any symptoms. “In 50%-60% of cases, the TSH value normalized at the second checkup without requiring any treatment,” Dr. Feldkamp explained.

The TSH value could be elevated for several reasons:

• Fluctuations depending on the time of day. At night and early in the morning, the TSH value is much higher than in the afternoon. An acute lack of sleep can lead to higher TSH values in the morning.
• Fluctuations depending on the time of year. In winter, TSH values are slightly higher than in the summer owing to adaptation to cooler temperatures. Researchers in the Arctic, for example, have significantly higher TSH values than people who live in warmer regions.
• Age-dependent differences. Children and adolescents have higher TSH values than adults do. The TSH values of adolescents cannot be based on those of adults because this would lead to incorrect treatment. In addition, TSH values increase with age, and slightly elevated values are initially no cause for treatment in people aged 70-80 years. Caution is advised during treatment, because overtreatment can lead to cardiac arrhythmias and a decrease in bone density.
• Sex-specific differences. The TSH values of women are generally a little higher than those in men.
• Obesity. In obesity, TSH increases and often exceeds the normal values usually recorded in persons of normal weight. The elevated values do not reflect a state of hypofunction but rather the body’s adjustment mechanism. If these patients lose weight, the TSH values will drop spontaneously. Slightly elevated TSH values in obese people should not be treated with thyroid hormones.

TOPLINE:

Matched cohort studies revealed infrequent adverse events (AEs) with either treatment, but the number needed to harm for any AE was more than three times higher with colchicine versus NSAIDs.

METHODOLOGY:

• The researchers conducted two matched retrospective cohort studies using the U.K. Clinical Practice Research Datalink and the Hospital Episode Statistics primary care datasets to compare AEs in adults initiating allopurinol for gout with and without colchicine or NSAID prophylaxis.
• For the study, 13,945 patients with gout who received colchicine were matched to 13,945 patients who received no prophylaxis. In addition, 25,980 patients with gout who received NSAIDs were matched to 25,980 who received no prophylaxis.
• The researchers used proportional hazard models to explore the associations between prophylaxis with either colchicine or NSAIDs and AEs.

TAKEAWAY:

• The incidence of most AEs was less than 200 per 10,000 patient-years, but the most common AE among patients given colchicine was diarrhea, with an incidence of 784.4 per 10,000 person-years, whereas the most common AE in those given NSAIDs was angina, with an incidence of 466.6 per 10,000 person-years.
• The number needed to harm in relation to any AE was 14.7 for colchicine, driven mainly by diarrhea, and 48.1 for NSAID.
• Compared with patients who started allopurinol without prophylaxis, those treated with colchicine were more likely to experience diarrhea, myocardial infarction, neuropathy, myalgia, and bone marrow suppression, whereas those treated with NSAIDs were more likely to experience angina, acute kidney injury, myocardial infarction, and peptic ulcer disease.
• Diarrhea, the most common AE, occurred in 17.9% of individuals who received colchicine.

IN PRACTICE:

“Our findings will provide much-needed information about the safety of flare prophylaxis that can inform treatment decisions and the choice between colchicine or NSAID for prophylaxis when initiating allopurinol, directly benefiting people with gout and their clinicians,” the authors write.

SOURCE:

First author Edward Roddy, MD, of Keele (England) University, and colleagues published their report online in BMJ’s Annals of the Rheumatic Diseases.

LIMITATIONS:

The study identified gout based on clinical diagnosis in primary care and only considered AEs serious enough to merit consultation or hospitalization; other limitations included the observational design and lack of data on the use of over-the-counter NSAIDs.

DISCLOSURES:

The study was supported by the National Institute for Health and Care Research’s Research for Patient Benefit program. The researchers had no financial conflicts to disclose.
