Diabetes

Clinicians frequently reach out to Catherine Varney, DO, asking if it’s safe to prescribe glucagon-like peptide 1 receptor agonists (GLP-1 RAs) to patients with thyroid disorders, such as hypothyroidism, goiter, hyperthyroidism, and nodules.

The concerns often stem from prior animal studies that revealed a link between the medications and abnormal alterations in thyroid C cells.

“What physicians need to understand is that the increased risk of thyroid cancers is specifically in those with a personal or family history of multiple endocrine neoplasia 2 (MEN2) syndrome or medullary thyroid carcinoma [MTC],” said Varney, an assistant professor of family medicine at the University of Virginia (UVA) and obesity medicine director for UVA Health, both in Charlottesville.

MTC is a common manifestation of the MEN2 syndrome, a genetic disorder that affects the endocrine glands and can cause tumors in the thyroid gland. However, MTC is very rare, making up only 3%-5% of all thyroid cancers, Varney said.

More common types of thyroid cancers, such as papillary thyroid cancer, are not contraindications to GLP-1 RAs, said Laura Davisson, MD, MPH, a professor of medicine and director of Medical Weight Management at West Virginia University, Morgantown. Papillary thyroid cancer makes up about 80% of all thyroid cancers.

If physicians are thinking about prescribing GLP-1 RAs, it’s important to learn the specific types of thyroid disorders in a patient or in their family history, Davisson said. A history of thyroid conditions, such as Graves disease, Hashimoto thyroiditis, or disorders requiring a patient to take thyroid medicine, such as levothyroxine, does not preclude a person from taking GLP-1 RAs.

If a patient does not know their family history, then a discussion about whether GLP-1 RAs are right for them should take place, Davisson said.

“They should take into consideration the risks and benefits of the medicine, and the fact that medullary thyroid cancer and MEN2 syndrome are rare, making the chances of them running in their family low,” she said. “If the patient understands the risks, they may decide the potential benefits may outweigh the risks.”

Keep in mind that the elevated risk for medullary thyroid carcinoma has not been clearly demonstrated in humans during clinical trials, only in rodents, Varney added. Rodents are more likely to develop thyroid cancer after exposure to a GLP-1 RA because rodents have higher numbers of GLP-1 receptors in their thyroid cells.

The risk for thyroid cancer is also dose dependent, and the amount of GLP-1 RA that induced thyroid tumors in the rodents was 8-60 times higher than that given to humans, Varney said.

“Nonetheless, there have been case reports of MTC in humans after taking GLP-1 RA,” she said.

 

What About GLP-1 RAs and Pancreatitis?

Pancreatitis is another condition that requires consideration when it comes to prescribing GLP-1 RAs.

While some studies show that GLP-1 RA analogs can increase the risk for pancreatitis, it’s important to know the reason behind pancreatitis before making a prescription decision, said Anila Chadha, MD, a family physician and obesity medicine physician at Dignity Health in Bakersfield, California.

If the pancreatitis is caused by alcohol or is medication induced, GLP-1 RAs are not recommended, Chadha said. If gallbladder stones are behind the pancreatitis, that’s different.

“If a patient has a well-documented history of gallstone-induced pancreatitis and the patient has had a cholecystectomy, it would be OK to prescribe GLP-1 [medications] after shared decision-making with the patient,” she said.

Some patients worry about taking GLP-1 RAs if they have other types of pancreatic disease beyond pancreatitis, said Davisson, but guidelines do not identify conditions such as pancreatic cysts or a family history of pancreatic cancer as contraindications to GLP-1 RAs.

However, be mindful that GLP-1 RA medications can increase gallbladder disease, Chadha said. A 2022 analysis in JAMA Internal Medicine, for example, found that the use of GLP-1 RAs was associated with an increased risk for gallbladder or biliary diseases, especially when used at higher doses, for longer durations, and for weight loss.

If a history of gallstones is present, physicians should tell patients that GLP-1 RA analogs can increase biliary colic, chances of cholecystitis, or even cholecystitis, Chadha said.

Gallbladder disease itself is not a contraindication, she said, but these patients can experience more disease complications when taking GLP-1 RAs.

Varney recently treated a middle-aged female patient who experienced biliary colic after taking a GLP-1 RA medication. The patient had a starting body mass index (BMI) of about 45 and lost 24% of her starting weight over 12 months using a combination of strengthening and cardiovascular training; a reduced-calorie, high-protein diet; and semaglutide for weight loss, Varney said.

The patient began developing upper gastrointestinal symptoms, including mild biliary colic, without concerning lab findings. An ultrasound revealed that she had new gallstones, compared with an ultrasound a few years prior. Varney started the patient on ursodeoxycholic acid, and over the course of 6 weeks, the patient’s symptoms gradually improved and eventually resolved.

“In a situation like this, many physicians might have discontinued the obesity medication, potentially deciding not to restart it due to the symptoms she was experiencing,” Varney said. “However, I believe it’s important to recognize that these medications offer far more than just weight loss benefits. The positive effects extend to cardiovascular, metabolic, and mental health, which are often overlooked when the focus is solely on the number on the scale or BMI.”

Other medical conditions that GLP-1 RAs may exacerbate include gastroparesis and diabetic retinopathy, Chadha noted. GLP-1 RA drugs can worsen these conditions and are not recommended for patients with such a history.

Nor are GLP-1 RA medications a good idea for patients struggling with severe constipation.

“It is very difficult to tolerate these medications because it can make constipation worse,” Chadha said. “In addition, if a patient struggles with severe heartburn, it can make the tolerability of these medications difficult.”

 

What Patients Should Know Before Using GLP-1 RAs

Not every overweight patient is a good candidate for GLP-1 RAs, and it’s important that doctors explain why the medications may not be right for them, Davisson said.

“If a patient only has a few pounds to lose (15-20 lb) and does not accept that these medications are intended to be a long-term treatment for the chronic diseases of diabetes or obesity, then they might not be a good candidate for the medication,” Davisson said.

Also essential is making sure patients are willing to follow appropriate healthy eating guidelines when on the medications, including getting enough protein and produce to maintain lean body mass and the necessary fiber to keep bowel habits regular.

Varney often hears concerns from physicians about the long-term effects of GLP-1 RAs. She said this class of medications has been used for nearly 20 years to treat type 2 diabetes, and the data over the past two decades have shown that the benefits of GLP-1 RAs far outweigh the risks for most patients.

Recent studies have also highlighted significant long-term benefits, including a marked reduction in cardiovascular events, heart failure, and kidney disease, she said.

“These outcomes underscore the effectiveness and safety of GLP-1 RAs not just for obesity treatment but for improving overall health, particularly in high-risk populations,” she said. “As physicians, it’s crucial to consider this extensive body of evidence when evaluating the use of these medications for patients, especially when the potential health benefits extend well beyond weight loss alone.”

TOPLINE:

Among older veterans with type 2 diabetes (T2D), the use of sodium-glucose cotransporter 2 (SGLT2) inhibitors as an add-on therapy is associated with a higher risk for peripheral artery disease (PAD)-related surgical events than the use of dipeptidyl peptidase 4 (DPP-4) inhibitors.

METHODOLOGY:

• Some placebo-controlled randomized trials have reported an increased risk for amputation with the use of SGLT2 inhibitors in patients with underlying cardiovascular diseases; however, the evidence remains unconfirmed by other subsequent trials.
• Researchers conducted a retrospective study of US veterans with T2D initiating SGLT2 inhibitors or DPP-4 inhibitors (a reference drug) as an add-on to metformin, sulfonylurea, or insulin treatment alone or in combination.
• The primary outcome was the time to the first surgical event for PAD (amputation, peripheral revascularization and bypass, or peripheral vascular stent).
• A Cox proportional hazards model was used to compare PAD event risk between the SGLT2 inhibitor and DPP-4 inhibitor groups, allowing events up to 90 days or 360 days after stopping SGLT2 inhibitors.

TAKEAWAY:

• After propensity score weighting, 76,072 episodes of SGLT2 inhibitor use (94% empagliflozin, 4% canagliflozin, and 2% dapagliflozin) and 75,833 episodes of DPP-4 inhibitor use (45% saxagliptin, 34% alogliptin, 15% sitagliptin, and 6% linagliptin) were included.
• Participants had a median age of 69 years and a median duration of diabetes of 10.1 years.
• SGLT2 inhibitor users had higher PAD-related surgical events than DPP-4 inhibitor users (874 vs 780), with event rates of 11.2 vs 10.0 per 1000 person-years (adjusted hazard ratio [aHR], 1.18).
• The cumulative probability of PAD-related surgical events at 4 years was higher for SGLT2 inhibitor users than for DPP-4 inhibitor users (4.0% vs 2.8%, respectively).
• The results remained consistent after 90 and 360 days of stopping SGLT2 inhibitors.
• SGLT2 inhibitor use was also associated with a higher risk for amputation (aHR, 1.15) and revascularization (aHR, 1.25) events than DPP-4 inhibitor use.

IN PRACTICE:

“These results underscore the need to determine the safety of [SGLT2 inhibitor] use among patients with diabetes who remain at very high risk for PAD,” the authors wrote.

SOURCE:

This study was led by Katherine E. Griffin, Geriatric Research Education and Clinical Center, Tennessee Valley Healthcare System, Nashville, and published online in Diabetes Care.

LIMITATIONS:

The study excluded patients whose initial diabetes treatment was not metformin, insulin, or sulfonylurea, which might have influenced the interpretation of the results. The median follow-up period of approximately 0.7 years for both groups may have affected the number of amputations and revascularization events observed. The study population primarily comprised White men, limiting generalizability to women and other demographic groups.

DISCLOSURES:

The study received funding through an investigator-initiated grant from the Veterans Affairs Clinical Science Research and Development. Two authors received partial research support through a grant from the Center for Diabetes Translation Research. All authors received partial support from the VETWISE-LHS Center of Innovation. No potential conflicts of interest relevant to the article were reported.

Evidence is mounting that new therapies already used to treat gut diseases, type 2 diabetes, and obesity may help people with alcohol use disorder (AUD).

Glucagon-like peptide 1 (GLP-1) receptor agonists, first used to treat diabetes and now widely used for weight loss, and fecal microbiota transplants (FMTs), used to treat diseases such as recurrent Clostridioides difficile infection, are advancing in clinical trials as potential options for treating AUD.

 

AUD Affects 28.9 Million People in the United States

In 2023, 28.9 million people aged 12 years or older in the United States had AUD (10.2% of the people in this age group). The Food and Drug Administration (FDA) has approved three medical therapies: Acamprosate, naltrexone, and disulfiram to help keep people with the disorder from returning to heavy drinking. Acamprosate’s mechanism of action is not clear, but it is thought to modulate and normalize alcohol-related changes in brain activity, thereby reducing withdrawal symptoms. Naltrexone blocks opioid receptors to reduce alcohol cravings. Disulfiram causes a toxic physical reaction when mixed with alcohol.

Some with AUD also benefit from behavioral therapies and support groups such as Alcoholics Anonymous. But for others, nothing has worked, and that’s part of the reason Lorenzo Leggio, MD, PhD, a scientist in the field of alcohol addiction with the National Institutes of Health (NIH), told this news organization that this is the “most exciting moment” for AUD treatment in his more than 2 decades of research in this area.

 

GLP-1 Agonists Showing Consistent Results

GLP-1 receptor agonists work by modulating the brain’s reward pathways, including the areas that regulate cravings and motivation.

“By dampening the reward signals associated with alcohol consumption, GLP-1 agonists may reduce cravings and heavy drinking episodes,” Fares Qeadan, PhD, MS, associate professor of biostatistics in the Department of Public Health Sciences at Loyola University Chicago in Illinois, told this news organization.

“The unique aspect of GLP-1 agonists is their ability to target both metabolic and reward systems in the brain,” he said. While naltrexone or acamprosate blocks the effects of alcohol or reduces withdrawal symptoms, “GLP-1 agonists approach addiction through a broader mechanism, potentially addressing underlying factors that contribute to cravings and compulsive behaviors,” he said.

As part of a study published in October in Addiction, Qeadan’s team found that people with AUD who were prescribed GLP-1 agonists had a 50% lower rate of severe intoxication than those who were not prescribed those medications.

“While this is observational and not yet definitive, it highlights the potential of these drugs to complement existing treatments for AUD,” he said.

Another study, a nationwide cohort study published in JAMA Psychiatry, found that using the GLP-1 receptor agonists semaglutide and liraglutide was linked to a lower risk for AUD-related hospitalizations than traditional AUD medications.

A systematic review, published last month in eClinical Medicine, concluded that, though there is little high-quality evidence demonstrating the effect of GLP-1 receptor agonists on alcohol use, “subgroup analysis from two [randomized, controlled trials] and supporting data from four observational studies suggest that GLP-1 [receptor agonists] may reduce alcohol consumption and improve outcomes in some individuals.”

Studying individual differences in response may have implications for personalized medicine, Qeadan said, as treatments could be tailored to those most likely to benefit, such as people with both metabolic dysfunction and AUD.

“These medications may offer hope for patients who struggle with addiction and have not responded to traditional therapies,” Qeadan said.

 

Exploring FMT as AUD Treatment

FMT is also a new research focus for treating AUD. Jasmohan Bajaj, MD, a gastroenterologist and liver specialist at Virginia Commonwealth University Medical Center, Richmond, is leading the Intestinal Microbiota Transplant in Alcohol-Associated Liver Disease (IMPACT) trial.

AUD has been linked with gut microbial alterations that worsen with cirrhosis. Research has shown that alcohol consumption changes the diversity of bacteria and can lead to bacterial overgrowth and progression of alcohol-associated liver disease.

FMT has been effective in rebalancing gut bacteria by transferring healthy stool from screened donors into patients who have developed an overgrowth of harmful bacteria. In the IMPACT trial, participants, who have not previously received traditional treatment for AUD or for whom treatment has not worked, are randomized either to the oral treatment capsule, which contains freeze-dried stool from a donor with healthy gut bacteria, or placebo.

The trial, sponsored by the NIH, is halfway through its target enrollment of 80.

In a previous smaller, placebo-controlled, phase 1 study, also led by Bajaj and published in Hepatology, 9 of the 10 volunteers who had severe AUD and cirrhosis experienced fewer alcohol cravings and had lower consumption after 15 days. Only three of the placebo participants saw similar improvements. Those who received the microbiota transplant also had fewer AUD-related events over 6 months.

Bajaj said that, if trials show FMT is safe and effective, he envisions the treatment as one tool in a multidisciplinary, integrated clinic that would include a hepatologist and mental health clinicians.

One benefit of the FMT treatment approach is it is given once or twice only, rather than administered regularly.

 

Current Treatments Work, But More are Needed

Leggio, who is clinical director of the National Institute on Drug Abuse Intramural Research Program, said: “We know that alcohol use disorder, and addiction in general, is a brain disease. We also know that the brain does not work in isolation. The brain is constantly interacting with the rest of the body, including with the gut.”

Leggio said it’s important to note that the three FDA-approved medications do work for alcohol addiction. He said they work as well as selective serotonin reuptake inhibitors for depression and beta-blockers for chronic heart failure.

But there are only three, and they don’t work for everyone, he noted. Those are among the reasons developing new treatments is important. New treatments could be used as an alternative or in combination with already approved treatments.

FMT is in “the very early stages” of trials testing its use for AUD, Leggio noted, adding that the studies by Bajaj’s team are among the very few addressing gut dysbiosis in AUD, and all have involved small numbers of patients. “It’s promising. It’s intriguing. It’s exciting. But we are just at the beginning.”

 

Results Consistent Across Species, Labs

GLP-1 agonists are further along in trials but still not ready for prescribing for AUD, Leggio said. The positive results have been consistent across species, different labs, and different research teams around the world.

Researchers have also explored through electronic health record emulation trials whether people already taking GLP-1 agonists for diabetes or obesity drink less alcohol compared with matched cohorts not taking GLP-1s. “They consistently show that the people who are on GLP-1s drink less,” he said.

“[Emulation trials] don’t replace the need for randomized controlled trials, Leggio noted. Leggio’s team is currently working on a randomized, placebo-controlled, double-blinded trial studying GLP-1s in relation to AUD.

 

New Directions 20-Year Highlight

This whole line of research represents “new hope” and has many implications, Leggio said. “I have been in this business for 20-plus years, and I think this is themost exciting moment when we have a very promising target in GLP-1s.”

Regardless of efficacy, he said, the focus on GLP-1 agonists and FMT for AUD has people talking more about addiction and the brain-body connection rather than assuming AUD is a result of poor choices and “bad behavior.”

The momentum of new treatments could also lead to patients and physicians having conversations about existing treatments.

“Hopefully, this momentum will help us destigmatize addiction, and by destigmatizing addiction, there will be an uptick in use of currently approved medications,” Leggio said.

Qeadan, Bajaj, and Leggio reported no relevant financial relationships.

Evidence is mounting that new therapies already used to treat gut diseases, type 2 diabetes, and obesity may help people with alcohol use disorder (AUD).

Glucagon-like peptide 1 (GLP-1) receptor agonists, first used to treat diabetes and now widely used for weight loss, and fecal microbiota transplants (FMTs), used to treat diseases such as recurrent Clostridioides difficile infection, are advancing in clinical trials as potential options for treating AUD.

 

AUD Affects 28.9 Million People in the United States

In 2023, 28.9 million people aged 12 years or older in the United States had AUD (10.2% of the people in this age group). The Food and Drug Administration (FDA) has approved three medical therapies: Acamprosate, naltrexone, and disulfiram to help keep people with the disorder from returning to heavy drinking. Acamprosate’s mechanism of action is not clear, but it is thought to modulate and normalize alcohol-related changes in brain activity, thereby reducing withdrawal symptoms. Naltrexone blocks opioid receptors to reduce alcohol cravings. Disulfiram causes a toxic physical reaction when mixed with alcohol.

Some with AUD also benefit from behavioral therapies and support groups such as Alcoholics Anonymous. But for others, nothing has worked, and that’s part of the reason Lorenzo Leggio, MD, PhD, a scientist in the field of alcohol addiction with the National Institutes of Health (NIH), told this news organization that this is the “most exciting moment” for AUD treatment in his more than 2 decades of research in this area.

Every year, an estimated 45 million Americans attempt some kind of diet to shed weight, especially after the holidays. Whether or not an individual is on a successful weight loss journey, at some point they probably will experience “diet fatigue.” This is the mental and emotional exhaustion associated with engaging in dieting behaviors like calorie counting, weighing and measuring food, meal planning and prepping, and restricting certain foods. 

Diet fatigue is a huge reason (but certainly not the only reason) why diets fail, as dieters can become so burned out that they ditch their diet, return to their former eating habits, blame themselves for their diet failure, and then repeat the cycle.

Alison* became my client just as her diet fatigue was starting to settle in. She had already lost 25 pounds in the prior 6 months while in a coaching program that focused primarily on hitting calorie and macro targets. She had been following an extremely high-protein regimen that relied heavily on animal sources and protein powders. I’m not against using powders to supplement protein needs, but in Alison’s case, she was consuming a powder-and-milk concoction twice per day in place of a meal with actual food. Not only had she become plain sick of the powder, but she was also concerned that all the protein was pushing vegetables off her plate. Alison had been following this plan quite strictly but admitted to indulging in weekend sweets. She recognized that this occasional indulgence could quickly morph into a full-on habit and undo her progress. While Alison had not yet reached her goal weight, we both agreed that she needed to change up her eating routine. 

Getting a patient through diet fatigue involves identifying which dieting behaviors are causing them the most angst and then guiding them toward a more sustainable approach that provides a similar benefit. For example, many dieters develop a huge disdain for calorie tracking, which they most often describe as tedious. One alternative to tracking calories is food journaling, which encourages accountability and mindfulness but is not as time-consuming as plugging every single ingredient you ingest into an app. Alison, however, didn’t have a problem with tracking, nor with weighing her food (as a Type A personality, she preferred having this kind of control). But she was clearly lacking a few things in her previous diet: variety, fiber, and flavor. In short, Alison was not enjoying her food — hence, her increased desire for treats on weekends, which she saw as a kind of reward for “being good” all week. 

To keep Alison from slipping into a weekend bingeing pattern, we discussed a few tweaks to her regimen. First, we had to ditch the protein powder in favor of balanced meals. I recommended reducing her daily protein target, which I felt was unnecessarily high. This provided some wiggle room to add a well-rounded dinner. I encouraged her to start adding spices and herbs to make dishes more exciting. 

Finally — and this one might be controversial — I encouraged Alison to actually plan for a weekly indulgence. In my experience working in the weight management space, complete restriction of a desired food always backfires, so it made sense for Alison to simply build the chocolate into her plan in a reasonable way. 

I’m confident that Alison will reach her weight loss goal (and keep the weight off) if food continues to bring her pleasure. When it comes to weight loss, I believe that if the solution is temporary, success will also be temporary. As a dietitian, preaching sustainable, long-term habit changes is my priority, not just because it’s responsible, but because it’s the only approach that truly works.

TOPLINE:

Mannkind expects to submit a request for a supplemental new drug application meeting to the Food and Drug Administration (FDA) for its inhaled human insulin (Afrezza Inhalation Powder). Currently indicated to improve glycemic control in adults with diabetes, the company announced 6-month results from its phase 3 INHALE-1 study of inhaled human insulin in children and adolescents aged 4-17.

METHODOLOGY:

• INHALE-1 is a 26-week, open-label clinical trial that randomized 230 subjects aged 4-17 years with type 1 or type 2 diabetes to either inhaled pre-meal insulin or multiple daily injections (MDI) of rapid-acting insulin analog, both in combination with basal insulin.
• The primary endpoint was a noninferior change in hemoglobin A1c levels, compared with MDI after 26 weeks.
• A 26-week extension phase in which all remaining MDI patients were switched to inhaled insulin is ongoing.

TAKEAWAY:

• In the full intent-to-treat (ITT) population analysis, the between-group difference in mean A1c change over 26 weeks exceeded the prespecified non-inferiority margin of 0.4% (0.435%), but this was largely driven by the variability of a single patient who didn’t adhere to the study protocol.
• A modified ITT analysis excluding that person did not exceed the predetermined threshold of 0.4% (0.370%), thereby establishing noninferiority of inhaled insulin with MDI.
• Over 26 weeks of treatment, there were no differences in lung function parameters between the treatment groups, with mean forced expiratory volume at 1 second (FEV1) at baseline vs 26 weeks of 2.901 liters (99.6% of predicted) vs 2.934 L (96.6%) in the inhaled insulin group and 2.948 L (102.3%) vs 2.957 (98%), respectively, in the MDI group.
• There were no differences between groups or concerns in other safety measures, including hypoglycemia.

IN PRACTICE:

“It was exciting to partner with MannKind and help lead this study to potentially expand the use of inhaled insulin, which is currently used successfully by many adults with diabetes, to a population that hasn’t had a treatment option other than injectable insulin in the history of their care,” said INHALE-1 investigator Roy W. Beck, MD, PhD, founder of the Jaeb Center for Health Research, Tampa, Florida.

“The 6-month results are clinically meaningful and show Afrezza as a potential future treatment option for a growing pediatric population living with type 1 and type 2 diabetes,” Beck added.

 

SOURCE:

The results of the study were announced at a Mannkind press release on December 16, 2024.

SAFETY INFORMATION:

Inhaled insulin is not recommended for the treatment of diabetic ketoacidosis or in patients who smoke or have recently stopped smoking.

Warning: Risk for acute bronchospasm in patients with chronic lung disease

• Acute bronchospasm has been observed in Afrezza-treated patients with asthma and chronic obstructive pulmonary disease (COPD)
• Afrezza is contraindicated in patients with chronic lung disease such as asthma or COPD
• Before initiating Afrezza, perform a detailed medical history, physical examination, and spirometry (FEV1) to identify potential lung disease in all patients
• Most common adverse reactions are hypoglycemia, cough, and throat pain or irritation.

TOPLINE:

Mannkind expects to submit a request for a supplemental new drug application meeting to the Food and Drug Administration (FDA) for its inhaled human insulin (Afrezza Inhalation Powder). Currently indicated to improve glycemic control in adults with diabetes, the company announced 6-month results from its phase 3 INHALE-1 study of inhaled human insulin in children and adolescents aged 4-17.

METHODOLOGY:

• INHALE-1 is a 26-week, open-label clinical trial that randomized 230 subjects aged 4-17 years with type 1 or type 2 diabetes to either inhaled pre-meal insulin or multiple daily injections (MDI) of rapid-acting insulin analog, both in combination with basal insulin.
• The primary endpoint was a noninferior change in hemoglobin A1c levels, compared with MDI after 26 weeks.
• A 26-week extension phase in which all remaining MDI patients were switched to inhaled insulin is ongoing.

TAKEAWAY:

• In the full intent-to-treat (ITT) population analysis, the between-group difference in mean A1c change over 26 weeks exceeded the prespecified non-inferiority margin of 0.4% (0.435%), but this was largely driven by the variability of a single patient who didn’t adhere to the study protocol.
• A modified ITT analysis excluding that person did not exceed the predetermined threshold of 0.4% (0.370%), thereby establishing noninferiority of inhaled insulin with MDI.
• Over 26 weeks of treatment, there were no differences in lung function parameters between the treatment groups, with mean forced expiratory volume at 1 second (FEV1) at baseline vs 26 weeks of 2.901 liters (99.6% of predicted) vs 2.934 L (96.6%) in the inhaled insulin group and 2.948 L (102.3%) vs 2.957 (98%), respectively, in the MDI group.

TOPLINE:

Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) and fenofibrates are associated with a reduced risk for diabetic macular edema (DME) in patients with type 2 diabetes, while calcium channel blockers appear to increase the risk.

METHODOLOGY:

• Researchers conducted a retrospective analysis of electronic medical records from the TriNetX health research network to evaluate how systemic medications, such as GLP-1 RAs, fenofibrates, thiazolidinediones, and calcium channel blockers, influence the risk of developing DME in patients with type 2 diabetes.
• They included patients with a 5-year history of type 2 diabetes and an absence of DME at baseline.
• The treatment group included patients who initiated treatment with calcium channel blockers (n = 107,193), GLP-1 RAs (n = 76,583), thiazolidinediones (n = 25,657), or fenofibrates (n = 18,606) after a diagnosis of diabetes. The control group received none of these medications within 1 year of being diagnosed with the condition.
• The researchers used propensity score matching to balance baseline characteristics and comorbidities between both groups.
• The primary outcome was the incidence of diagnoses of DME within a 2-year follow-up period after the initiation of systemic medications.

TAKEAWAY:

• Patients treated with calcium channel blockers showed an increased risk for incident DME (hazard ratio [HR], 1.66; 95% CI, 1.54-1.78) compared with control individuals.
• Treatment with GLP-1 RAs was associated with a reduced risk for DME (HR, 0.77; 95% CI, 0.70-0.85), as was treatment with fenofibrates (HR, 0.83; 95% CI, 0.68-0.98).
• No significant difference in risk for DME was observed between patients taking thiazolidinediones and control individuals.

IN PRACTICE:

“We found a possible protective effect for GLP-1 RA medications and fenofibrate for DME and an adverse effect for calcium channel blockers with regard to the development of DME in patients” with type 2 diabetes, the authors wrote.

“Our preliminary data suggests a protective effect with regard to GLP-1 RA drugs and the development of DME. Clinical studies examining a potential therapeutic effect of GLP-1 RA drugs on DME do seem warranted. A single orally administered drug could conceivably lower blood sugar, reduce weight, offer cardiovascular protection, and treat DME” in patients with type 2 diabetes, they added.

 

SOURCE:

The study was led by Jawad Muayad, BS, of the School of Medicine at Texas A&M University, in Houston. It was published online on December 5, 2024, in Ophthalmology Retina.

LIMITATIONS:

The study was retrospective in nature. It relied on electronic medical records for the diagnosis of DME instead of directly assessing retinal images or measuring retinal thickness. Moreover, patients on certain medications may have been monitored more closely, potentially influencing the likelihood of a diagnosis of DME being recorded.

DISCLOSURES:

The study did not receive any funding support. One author disclosed receiving consulting fees from various institutions and pharmaceutical companies. The other authors reported no relevant conflicts of interest.

Glucagon-like peptide 1 (GLP-1) receptor agonists led to a significant reduction in the risk for venous thromboembolism (VTE) among individuals with type 2 diabetes, compared with dipeptidyl peptidase 4 (DPP-4) inhibitors, a recent analysis indicated.

Overall, GLP-1 agonist use was associated with a 20% reduction in VTE, compared with DPP-4 inhibitor use, in those with type 2 diabetes, and this benefit held regardless of people’s obesity status, said study investigator Cho-Han Chiang, MD, a medical resident at Mount Auburn Hospital, Cambridge, Massachusetts, who presented the findings at the American Society of Hematology (ASH) 2024 Annual Meeting.

The incidence of VTE has increased by 20% over the past 10 years, and obesity is a risk factor for VTE, Chiang explained. A growing body of evidence demonstrated that GLP-1s provide a variety of cardiovascular benefits in people with type 2 diabetes, but data on VTE benefits remain more limited.

In the retrospective study, the researchers combed electronic health records from the TriNetX global database, which includes more than 250 million patients, and identified adults with type 2 diabetes who were taking a GLP-1 agonist or a DPP-4 inhibitor.

After excluding anyone with prior VTE or atrial fibrillation as well as those treated with both drugs or with oral anticoagulants, patients on GLP-1s were matched with those on DPP-4 inhibitors based on predetermined variables, including age, sex, race, body mass index (BMI), hemoglobin A1c, use of other antidiabetic agents, and underlying comorbidities. VTE was a composite of pulmonary embolism and deep vein thrombosis.

The researchers also performed a subgroup analysis that stratified patients by obesity status, defined as a BMI ≥ 30.

Within 1 year of GLP-1 or DPP-4 prescription, VTE occurred at a rate of 6.5 cases/1000 person-years in the GLP-1 group vs 7.9 cases/1000 person years in the DPP-4 inhibitor group (hazard ratio [HR], 0.80; P < .001).

The 20% risk reduction in VTE held across various subgroups of BMI, including among those with obesity, Chiang reported.

Among patients with the highest BMI (≥ 40), VTE occurred at a rate of 7.2 cases/1000 person years in the GLP-1 group vs 9.6 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.74). Among patients with the next highest BMI (30-34.9), VTE occurred at a rate of 4.8 cases/1000 person years in the GLP-1 group vs 7.9 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.60). Among those with the lowest BMI (18.5-24.9), VTE occurred significantly less frequently among those in the GLP-1 group — 4.7 cases/1000 person years vs 7.4 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.61).

The lower risk for VTE associated with GLP-1s also held across the individual components of the composite VTE. Pulmonary embolism occurred at a rate of 3.1 cases/1000 person years in the GLP-1 group vs 3.9 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.78), and deep vein thrombosis occurred in 4.2 cases/1000 person years in the GLP-1 group vs 5.0 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.82).

Interestingly, the GLP-1 and DPP-4 curves started diverging within the first 30 days of the index prescription date, said Chiang.

Session moderator Ghadeer Dawwas, PhD, said in an interview that patients with type 2 diabetes are increasingly using GLP-1 agonists because of the cardiovascular benefits associated with the agents, which include lower risks for stroke and heart failure, but the antithrombotic benefits are still debated.

“The current study indicates that GLP-1 agonists may help lower the risk of VTE in patients with type 2 diabetes, irrespective of their baseline body weight,” said Dawwas, a pharmacoepidemiologist and assistant professor of medicine at Vanderbilt University Medical Center in Nashville, Tennessee. “However, given the current landscape of evidence and the existence of conflicting data on VTE risk, clinicians should proceed with caution and await further studies to validate these findings before making clinical decisions.”

This study was funded by the National Blood Clot Alliance and Conquer Cancer Foundation. Chiang and Dawwas had no disclosures.

The American Diabetes Association (ADA)’s Standards of Care — 2025 offer new guidance on broader use of continuous glucose monitoring (CGM), use of glucagon-like peptide 1 receptor agonists (GLP-1 RAs) beyond weight loss, management of metabolic dysfunction-associated liver disease (MAFLD), plus a strong endorsement for drinking water and much more. 

The Standards of Care — 2025 were published December 9 as a supplement to Diabetes Care. The standards “incorporate the latest information from clinical trial data and knowledge of diabetes management into a comprehensive guidelines document that will assist physicians in managing patients with diabetes in their practices,” said Mandeep Bajaj, MBBS, ADA’s President, Medicine & Science.

In an interview, Bajaj highlighted some of the most important of the clinical updates in 2024, including the following: 

• Consideration of the use of continuous glucose monitoring devices in adults with type 2 diabetes (T2D) who don’t use insulin. Medicare and many other payers currently only cover CGM for people who use insulin or are otherwise at risk for hypoglycemia. However, some CGMs are now available over the counter, Bajaj pointed out.
• Actions to be taken in the event of medication shortages. The ADA published guidance for this in the case of GLP-1 RAs on December 2. Essentially ADA advised substituting a different GLP-1 RA if possible. Nonapproved products aren’t recommended, but guidance is provided for people who choose to use them.
• Use of GLP-1 RAs for heart and kidney health. Recommendations were revised to explicitly advise on choice of pharmacotherapy for individuals with T2D, based on new data on those with established or high risk for atherosclerotic cardiovascular disease, heart failure with preserved ejection fraction, and chronic kidney disease.
• Treatment of MAFLD with moderate or advanced liver fibrosis. A new recommendation for use of a thyroid hormone receptor–beta agonist is based on trial data for resmetirom. Moreover, Bajaj noted, “we’ve adopted the new nomenclature, which was previously NAFLD and NASH, and now is MAFLD and MASH [metabolic-associated steatohepatitis].”
• Advice to continue weight management therapy beyond achieving weight loss goals. This is based on a large amount of evidence that “stopping these therapies are associated with weight regain and increased cardiovascular risk,” Bajaj said, adding that this recommendation was made in collaboration with the Obesity Society.
• Antibody-based screening for presymptomatic T1D in family members of people with T2D and others who may be at risk. “Individuals who test autoantibody positive should be provided with or referred for counseling about the risk of developing diabetes, diabetes symptoms, and [diabetic ketoacidosis] prevention and should be given consideration for referral to a specialized center for further evaluation and/or consideration of a clinical trial or approved therapy to potentially delay development of clinical diabetes,” the document says.
• Screen for psychosocial issues. People with diabetes should be screened for concerns including diabetes distress, depression, anxiety, fear of hypoglycemia, and disordered eating behaviors. “People on insulin or sulfonylureas may have fear of hypoglycemia, but diabetes distress can happen to anyone with diabetes,” Bajaj pointed out. Caregivers and family members should be screened as well, the document advises.
• Drink water, not soda. In the nutrition section, a new recommendation strongly advises drinking water instead of nutritive or nonnutritive sweetened beverages. “This is an important recommendation. So, when patients ask what’s the best thing to drink, our answer is drink water rather than Coca Cola or Diet Coke,” Bajaj said. But, what about people with diabetes who can’t quit their diet soda habit? “We’ve said that the nonnutritive sweetener is preferred over sugar sweetener, provided it’s in moderation and short term ... but the best is water.”

The American Diabetes Association (ADA)’s Standards of Care — 2025 offer new guidance on broader use of continuous glucose monitoring (CGM), use of glucagon-like peptide 1 receptor agonists (GLP-1 RAs) beyond weight loss, management of metabolic dysfunction-associated liver disease (MAFLD), plus a strong endorsement for drinking water and much more. 

The Standards of Care — 2025 were published December 9 as a supplement to Diabetes Care. The standards “incorporate the latest information from clinical trial data and knowledge of diabetes management into a comprehensive guidelines document that will assist physicians in managing patients with diabetes in their practices,” said Mandeep Bajaj, MBBS, ADA’s President, Medicine & Science.

In an interview, Bajaj highlighted some of the most important of the clinical updates in 2024, including the following: 

• Consideration of the use of continuous glucose monitoring devices in adults with type 2 diabetes (T2D) who don’t use insulin. Medicare and many other payers currently only cover CGM for people who use insulin or are otherwise at risk for hypoglycemia.

TOPLINE:

Increased cutaneous carbonyl stress is linked to slower nerve conduction in patients with metabolically well-controlled, recent-onset type 2 diabetes (T2D) and can predict the development of neuropathic deficits over 5 years.

METHODOLOGY:

• Accumulation of advanced glycation end products (AGEs), which results from endogenous carbonyl stress, may be a potential target for preventing and treating the diabetic sensorimotor polyneuropathy (DSPN) that is a common complication of T2D.
• Researchers investigated novel cutaneous biomarkers for the development and progression of DSPN in 160 individuals with recent-onset T2D (diagnosed within 12 months or less) and 144 individuals with normal glucose tolerance, all recruited consecutively from the German Diabetes Study baseline cohort.
• Peripheral nerve function was assessed through nerve conduction studies, quantitative sensory testing, and clinical neuropathy scores.
• Skin biopsies were used to analyze intraepidermal nerve fiber density, endothelial integrity, cutaneous oxidative stress markers, and cutaneous carbonyl stress markers, including AGE autofluorescence and argpyrimidine area.
• Skin autofluorescence was measured noninvasively using an AGE reader device.
• A subgroup of 80 patients with T2D were reassessed after 5 years to evaluate the progression of neurophysiological deficits.

TAKEAWAY:

• Patients with recent-onset T2D had greater AGE autofluorescence and argpyrimidine area (P ≤ .05 for both) and lower nerve fiber density (P ≤ .05) than individuals with normal glucose tolerance.
• In patients with T2D, AGE autofluorescence was inversely associated with nerve conduction (P = .0002, P = .002, and P = .001 for peroneal motor, median motor, and sural sensory nerve conduction velocity, respectively) and positively associated with AGE reader measurements (P < .05); no such associations were observed in those with normal glucose tolerance.
• In the prospective T2D cohort, associations were noted between cutaneous markers for AGEs and endothelial cells at baseline and changes in nerve function indices over a 5-year period.

IN PRACTICE:

“Prospective analyses revealed some predictive value of cutaneous AGEs and lower endothelial integrity for declining nerve function, supporting the role of carbonyl stress in the development and progression of DSPN, representing a potential therapeutic target,” the authors wrote.

SOURCE:

The study was led by Gidon J. Bönhof, Department of Endocrinology and Diabetology, Medical Faculty, University Hospital Düsseldorf, Heinrich Heine University Düsseldorf, Düsseldorf, Germany. It was published online in Diabetes Care.

LIMITATIONS:

The observational design of the study limited the ability to draw causal conclusions. The groups were not matched for age or body mass index. Various mechanisms related to DSPN were analyzed; however, specific pathways of AGEs were not studied in detail. The relatively low number of individuals with clinically manifested DSPN limited the exploration of different stages of the condition.

DISCLOSURES:

The study was supported by a German Center for Diabetes Research grant. The German Diabetes Study was supported by the German Diabetes Center funded by the German Federal Ministry of Health (Berlin), the Ministry of Innovation, Science, Research and Technology of North Rhine-Westphalia (Düsseldorf, Germany), and grants from the German Federal Ministry of Education and Research to the German Center for Diabetes Research e.V. No relevant conflicts of interest were reported.

They’re literally not better. Idealistically, sure, but literally not. And there’s really no debate. Meaning there’s never been a reproducible diet and exercise intervention that has led to anywhere near the average weight lost by those taking obesity medications. Furthermore, when it comes to the durability of weight lost, the gulf between outcomes with diet and exercise vs obesity medications is even more dramatic.

Looking to the literature, one of the most trotted out studies on lifestyle’s impact on weight over time is the Look AHEAD trial. Before useful obesity medications came on the scene, I trotted it out myself. Why? Because it was heartening when faced with the societal refrain that diet and exercise never worked to be able to show that yes, in fact they do. But how well?

Looking to Look AHEAD’s 4-year data (Obesity [Silver Spring]. 2011 Oct;19[10]:1987-1998), those randomized to the intensive lifestyle initiative arm averaged a 4.7% total body weight loss – an amount that remained the same at 8 years. But I chose 4 years because that’s a better comparison with the semaglutide SELECT trial that revealed at 4 years, the average sustained weight lost was more than double that of Look AHEAD’s, at 10.2%. Meanwhile the recently released SURMOUNT-4 study on tirzepatide reported that at 88 weeks, the average weight lost by participants was a near bariatric surgery level of 25.3% with no signs suggestive of pending regains.

Now maybe you want to cling to the notion that if you just try hard enough, your diet and exercise regime can beat our new meds. Well, it’s difficult to think of a more miserable, often actual vomit-inducing intervention, than the spectacle that used to air weekly on prime time called The Biggest Loser, where participants lived on a ranch and were berated and exercised all day long for the chance to lose the most and win a quarter of a million dollars. But even there, the meds prove to be superior. Although the short-term Biggest Loser data do look markedly better than meds (and than bariatric surgery), whereby the average participant lost 48.8% of their body weight during the grueling 7-month long, 24/7 competition, by postcompetition year 6, the average weight lost dropped to 12.7%.

Yet on November 26, when word came out that Medicare is likely to extend coverage to obesity medications for far more Americans, one of the most common refrains was something along the lines of yes, lifestyle modification is the best choice for dealing with obesity but it’s good that there will be medication options for those where that’s insufficient.

What?

The only reason that the world isn’t comfortable with the eminently provable truth that diet and exercise are inferior to obesity medications for weight management is weight bias. The message is that people simply aren’t trying hard enough. This despite our comfort in knowing that medications have more of an impact than lifestyle on pretty much every other chronic disease. Nor can I recall any other circumstance when coverage of a remarkably effective drug was qualified by the suggestion that known-to-be-inferior interventions are still the best or favored choice.

At this point, obesity medications are plainly the first-line choice of treatment. They provide not only dramatically greater and more durable weight loss than lifestyle interventions, they have also been shown to very significantly reduce the risk for an ever-growing list of other medical concerns including heart attacks, strokes, type 2 diabetes, hypertension, sleep apnea, fatty liver disease, and more, while carrying minimal risk.

Let it also be said that improvements to diet and exercise are worth striving for at any weight, though one should not lose sight of the fact that perpetual, dramatic, intentional, behavior change in the name of health requires vast amounts of wide-ranging privilege to enact — amounts far beyond the average person’s abilities or physiologies (as demonstrated with obesity by decades of disappointing long-term lifestyle outcome data). 

Let it also be said that some people will indeed find success solely through lifestyle and that not every person who meets the medical criteria for any medication’s prescription, including obesity medications, is required or encouraged to take it. The clinician’s job, however, at its most basic, is to inform patients who meet medical use criteria of their options, and if a medication is indicated, to inform them of that medication’s risks and benefits and expected outcomes, to help their patients come to their own treatment decisions.

It’s not a bad thing that we have medications that deliver better outcomes than lifestyle — in fact, it’s terrific, and thankfully that they do is true for pretty much every medical condition for which we have medication. That’s in fact why we have medications! And so this constant refrain of golly-gee wouldn’t it be better if we could just manage obesity with lifestyle changes needs to be put to rest — we literally know it wouldn’t be better, and it’s only weight bias that would lead this evidence-based statement to seem off-putting.

The clinician’s job, however, at its most basic, is to inform patients who meet medical use criteria of their options, and if a medication is indicated, to inform them of that medication’s risks and benefits and expected outcomes, to help their patients come to their own treatment decisions.

It’s not a bad thing that we have medications that deliver better outcomes than lifestyle — in fact, it’s terrific, and thankfully that they do is true for pretty much every medical condition for which we have medication. That’s in fact why we have medications! And so this constant refrain of golly-gee wouldn’t it be better if we could just manage obesity with lifestyle changes needs to be put to rest — we literally know it wouldn’t be better, and it’s only weight bias that would lead this evidence-based statement to seem off-putting.
