Diabetes

Approximately one-quarter of mothers with diabetes failed induction of labor, and this failure was associated with a range of adverse outcomes for mothers and infants, based on data from more than 2,000 individuals.

Uncontrolled diabetes remains a risk factor for cesarean delivery, Ali Alhousseini, MD, of Corewell Health East, Dearborn, Michigan, and colleagues wrote in a study presented at the annual clinical and scientific meeting of the American College of Obstetricians and Gynecologists.

“Identifying and stratifying associated risk factors for failed induction of labor [IOL] may improve counseling and intrapartum care,” the researchers wrote in their abstract.

The researchers reviewed data from 2,172 mothers with diabetes who underwent IOL at a single university medical center between January 2013 and December 2021. They examined a range of maternal characteristics including age, ethnicity, gestational age, medical comorbidities, insulin administration, parity, and health insurance.

A total of 567 mothers with diabetes (26.1%) failed IOL and underwent cesarean delivery.

Overall, failed IOL was significantly associated with nulliparity (P = .0001), as well as preexisting diabetes compared with gestational diabetes, diabetes control with insulin, maternal essential hypertension, preeclampsia, and polyhydramnios (P = .001 for all). Other factors significantly associated with failed IOL included prenatal diagnosis of fetal growth restriction (P = .008), and placental abnormalities (P = .027).

Neonatal factors of weight, large for gestational age, head circumference, and height were not significantly associated with failed IOL (P > .05 for all).

As for neonatal outcomes, failed IOL was significantly associated with admission to neonatal intensive care unit, hyperbilirubinemia, and longer hospital stay (P = .001 for all). Failed IOL was significantly associated with lower 1-minute APGAR scores, but not with lower 5-minute APGAR scores, the researchers noted (P = .033 for 1-minute score). No association was noted between failed IOL and neonatal readmission, lower umbilical cord pH value, or maternal ethnicity.

The findings were limited by the retrospective design, but data analysis is ongoing, Dr. Alhousseini said. The researchers are continuing to assess the roles not only of optimal glucose control, but other maternal factors in improving maternal and neonatal outcomes, he said.
 

Data Add to Awareness of Risk Factors

The current study is important because of the increasing incidence of diabetes and the need to examine associated risk factors in pregnancy, Michael Richley, MD, a maternal fetal medicine physician at the University of Washington, Seattle, said in an interview. “The average age of onset of diabetes is becoming younger and type 2 diabetes in pregnancy is an increasingly common diagnosis,” said Dr. Richley, who was not involved in the study.  

The increase in both maternal and neonatal adverse outcomes is expected given the risk factors identified in the study, said Dr. Richley. “The patients with diabetes also were sicker at baseline, with hypertensive disorders, growth restriction, and pregestational diabetes,” he noted.

The study findings support data from previous research, Dr. Richley said. The message to clinicians is that patients with diabetes not only have an increased risk of needing a cesarean delivery but also have an increased risk of poor outcomes if a cesarean delivery is needed, he said.

Although a prospective study would be useful to show causality as opposed to just an association, such a study is challenging in this patient population given the limitations of conducting research on labor and delivery, he said.

The study received no outside funding. The researchers and Dr. Richley had no financial conflicts to disclose.

Artificial intelligence (AI) has drawn interest in ophthalmology for its potential to track disease trends in huge populations, such as the 38.4 million people in the United States with diabetes who are at risk for diabetic eye disease. However, a recent study using AI to detect diabetic retinopathy from retinal photo screenings has found wide disparities in the quality of data being fed into the algorithm.

And screening photos captured in nine primary care settings were three times more likely to be unusable than those obtained in two ophthalmology clinics, a study at Temple University in Philadelphia found. The results of the new research were reported at the Association for Research in Vision and Ophthalmology (ARVO) 2024 annual meeting.

“AI-assisted diabetic retinopathy screenings were more successful when completed in the ophthalmology clinic setting compared to the primary care setting,” study leader Madelyn Class, a medical student at Temple, told this news organization. One key difference, Ms. Class said, was that the specialty clinics used a photographer training in capturing ophthalmic images, while the primary care sites had medical assistants taking the photos.
 

Challenges of Screening in Primary Care

The American Diabetes Association acknowledged in a 2017 position statement that retinal photography has the potential to bring screening into settings where optometrists or ophthalmologists are unavailable. This study showed the potential may not yet be realized.

In the primary care setting, 42.5% of retinal photos were ungradable compared with 14.5% in the specialty settings.

The number of patients diagnosed with more-than-mild diabetic retinopathy also varied significantly between the two settings — 13% in primary care and 24% in ophthalmology — as did the rates of follow-up appointments: 58% and 80%, respectively.

“It seems user error played a role in the quality of photographs that were taken,” Ms. Class said. “Some of the images we received from the primary care settings were actually of the eyelid, or even the curtains on the wall, rather than the fundus.

“All the camera operators in the study received training on the imaging device,” Ms. Class added. “This suggests that some of the photographers were rushed, out of practice, or simply no longer interested in taking photos,” she said. “Apparently, we will have to continuously monitor the performance of each photographer to ensure that quality photos are being taken.”

The findings may also point to the need for using different equipment for screening in primary care, Ms. Class added. “Robotic as opposed to manual cameras may help eliminate some of the user error that was experienced with primary care screenings,” she said.

Need for Training ‘Fixable’

These findings demonstrate the challenges of capturing usable retinal images outside of an eye care professional’s office, according to Jennifer Lim, MD, director of the retina service at the University of Illinois Chicago.

“This study illustrates that implementation is the rub of AI,” Dr. Lim told this news organization. “Getting primary care doctors and clinics to want to adopt and figure out how to implement AI screening [for diabetic retinopathy] in a healthcare system is difficult, so I applaud the Temple University system for trying to integrate retinal photography-based AI screening into the primary care outpatient centers and comparing outcomes to the ophthalmology clinics.”

The study showed that photographers need not only initial training but also monitoring to avoid ungradable images, Dr. Lim added, a problem that is “fixable.”

“It’s going to take a lot of work to get the message out to the primary care practices that these autonomous, cloud-based systems are available and effective for detecting retinopathy,” she said.

But the effort is worth it, she added: “It doesn’t take much time to take these photos for diabetic retinopathy screening, and the potential benefits are huge because the earlier you diagnose diabetic retinopathy that’s more than mild, the more likely the patient can be sent for eye care in a timely fashion and thus prevent visual loss from diabetic retinopathy.”

Ms. Class had no relevant disclosures. Dr. Lim disclosed a past relationship with Eyenuk, the maker of retinal screening cameras.

TOPLINE:

Various food additive emulsifiers, including total carrageenans, carrageenan gum, tripotassium phosphate, sodium citrate, and guar gum, can increase the risk for type 2 diabetes (T2D), showed a recent study.

METHODOLOGY:

• Food emulsifiers, which are extensively used to enhance the texture and improve the shelf life of various ultraprocessed food items, have been shown to increase the risk for cardiovascular disease and cancer.
• In this study, the dietary intake data of 104,139 adults (79.2% women; mean age, 42.7 years) enrolled in the French NutriNet-Santé prospective cohort study from May 2009 to April 2023 were assessed for 24 hours on 3 nonconsecutive days at inclusion and every 6 months thereafter to determine the risk for T2D.
• The dietary records of participants, which were linked to food composition databases, were used to quantify the food additive intake.
• T2D cases were identified using a multisource approach encompassing self-reports, health questionnaires, national health insurance system databases, and/or mortality registries.

TAKEAWAY:

• During a mean follow-up period of 6.8 years, 1056 incident cases of T2D were reported.
• Almost all (99.7%) participants were exposed to at least one food additive emulsifier, with the main contributors being ultraprocessed fruits and vegetables (18.5%), cakes and biscuits (14.7%), and dairy products (10.0%).
• The intake of the following emulsifiers increased the risk for T2D:
• Total carrageenans and carrageenan gum (3% increased risk per increment of 100 mg/d; P < .001)
• Tripotassium phosphate (15% increased risk per increment of 500 mg/d; P = .023)
• Acetyl tartaric acid esters of monoglycerides and diglycerides of fatty acids (4% increased risk per increment of 100 mg/d; P = .042)
• Sodium citrate (4% increased risk per increment of 500 mg/d; P = .008)
• Guar gum (11% increased risk per increment of 500 mg/d; P < .0001)
• Gum arabic (3% increased risk per increment of 1000 mg/d; P = .013)
• Xanthan gum (8% increased risk per increment of 500 mg/d; P = .013)

IN PRACTICE:

In an accompanying commentary, experts postulated that “findings from this and other studies could prompt regulatory agencies and policymakers to reconsider the rules governing the use of emulsifiers and other additives by the food industry such as setting limits and requiring better disclosure of food additive contents to help consumers make more informed choices.”

SOURCE:

Clara Salame, PhD, Université Sorbonne Paris Nord and Université Paris Cité, INSERM, INRAE, CNAM, Center of Research in Epidemiology and Statistics, Nutritional Epidemiology Research Team, Paris, France, led this study, which was published online in The Lancet Diabetes & Endocrinology.

LIMITATIONS:

The observational nature of this study is not sufficient to establish causality relationships. There may have been measurement errors in emulsifier exposure, particularly in products exempted from labeling requirements. This cohort’s demographics, which included a higher percentage of women and a health-conscious population, may affect the generalizability of the study’s findings.

DISCLOSURES:

This study received funding from the European Research Council, and the NutriNet-Santé study was supported by many public institutions such as the Ministère de la Santé, Santé publique France, Université Sorbonne Paris Nord, and others. The authors declared no conflicts of interest.

Eli Lilly has announced positive phase 3 top-line results for its once-weekly insulin efsitora alfa (efsitora) in insulin-naive adults with type 2 diabetes and those who require multiple daily insulin injections.

The new data come from the company’s QWINT-2 and QWINT-4 phase 3 clinical trials. In both, efsitora was noninferior to daily basal insulin in lowering A1c. The comparator was once-daily degludec in QUINT-2 and glargine in QUINT-4.

These results come days before the once-weekly competitor, Novo Nordisk’s insulin icodec, will be discussed by the US Food and Drug Administration’s Endocrinologic and Metabolic Drugs Advisory Committee. On May 24, 2024, the panel will review safety and efficacy of icodec for the proposed indication of improving glycemic control in adults with diabetes.
 

Hypoglycemia and Affordability Are Concerns

Asked to comment, Anne L. Peters, MD, director of the University of Southern California Westside Center for Diabetes, Los Angeles, told this news organization that she’s “cautiously optimistic” about once-weekly insulin. “I honestly think it’s going to have an important role in diabetes. … And I’m looking forward to learning how it’s going to help my patients.”

However, Dr. Peters also said she’s concerned about the possible risk for hypoglycemia with long-acting insulin, particularly in patients with variable schedules. “The real fear they have and I have is hypoglycemia. That being said, I think that it will be great for some patients where hypoglycemia is less of a concern, and they’re in a more stable environment. … I think there are patients who will really benefit but I have to figure out who those patients are.”

Dr. Peters, who takes care of many low-income patients, also pointed out that once approved, these newer insulins may not be affordable for those who could most benefit from them in terms of improved adherence. Insurance plans may not cover them initially, especially given that the data thus far show noninferiority, not superiority, to daily basal. “The patients in whom I would like to use it most are the patients who have the most trouble with social determinants of health and other issues. I really think it could really make a difference for them, but it won’t get there for a while.”

And, she noted, titrating doses of once-weekly insulin will likely come with a learning curve. “Having spent a lifetime adjusting basal insulin on a daily basis to suddenly do it on a weekly basis, as a diabetologist I’m going to have to get used to what that feels like.”
 

Topline Data Show Noninferiority to Daily Basal Insulin

In QWINT-2, efficacy and safety of once-weekly efsitora was compared with those of once-daily insulin degludec for 52 weeks. Study participants were all new to using insulin, but some were using glucagon-like peptide 1 receptor agonists.

The treat-to-target trial met its primary noninferiority endpoint for hemoglobin A1c reduction at week 52. A1c values were lowered by 1.34 percentage points with efsitora compared with 1.26 for insulin degludec, resulting in non–significantly different A1c values of 6.87% and 6.95%, respectively.

In QWINT-4, efficacy and safety of once-weekly efsitora was compared with those of daily insulin glargine for 26 weeks in adults with type 2 diabetes who had previously been treated with basal insulin and at least two injections of premeal insulin per day. Participants were randomized to receive efsitora once weekly or insulin glargine once daily, and both groups used lispro before meals.

This trial also met its primary endpoint, with both reducing A1c by 1.07 percentage points at 26 weeks, resulting in levels of 7.12% and 7.11%, respectively.

The full results for QWINT-2 will be presented at the European Association for the Study of Diabetes meeting this September.

Eli Lilly has announced positive phase 3 top-line results for its once-weekly insulin efsitora alfa (efsitora) in insulin-naive adults with type 2 diabetes and those who require multiple daily insulin injections.

The new data come from the company’s QWINT-2 and QWINT-4 phase 3 clinical trials. In both, efsitora was noninferior to daily basal insulin in lowering A1c. The comparator was once-daily degludec in QUINT-2 and glargine in QUINT-4.

These results come days before the once-weekly competitor, Novo Nordisk’s insulin icodec, will be discussed by the US Food and Drug Administration’s Endocrinologic and Metabolic Drugs Advisory Committee. On May 24, 2024, the panel will review safety and efficacy of icodec for the proposed indication of improving glycemic control in adults with diabetes.

Serious mental illness (SMI), including bipolar disorder or schizophrenia spectrum disorders, is associated with a twofold increased risk for comorbid physical illness, results of a new meta-analysis showed.

“Although treatment of physical and mental health remains siloed in many health services globally, the high prevalence of physical multimorbidity attests to the urgent need for integrated care models that address both physical and mental health outcomes in people with severe mental illness,” the authors, led by Sean Halstead, MD, of The University of Queensland Medical School in Brisbane, Australia, wrote.

The findings were published online in The Lancet Psychiatry.
 

Shorter Lifespan?

SMI is associated with reduced life expectancy, and experts speculate that additional chronic illnesses — whether physical or psychiatric — may underlie this association.

While previous research has paired SMI with comorbid physical illnesses, the researchers noted that this study is the first to focus on both physical and psychiatric multimorbidity in individuals with SMI.

The investigators conducted a meta-analysis of 82 observational studies comprising 1.6 million individuals with SMI and 13.2 million control subjects to determine the risk for physical or psychiatric multimorbidity.

Studies were included if participants were diagnosed with either a schizophrenia spectrum disorder or bipolar disorder, and the study assessed either physical multimorbidity (at least two physical health conditions) or psychiatric multimorbidity (at least three psychiatric conditions), including the initial SMI.

Investigators found that individuals with SMI had more than a twofold increased risk for physical multimorbidity than those without SMI (odds ratio [OR], 2.40; 95% CI, 1.57-3.65; P = .0009).

Physical multimorbidity, which included cardiovascular, endocrine, neurological rental, gastrointestinal, musculoskeletal, and infectious disorders, was prevalent at similar rates in both schizophrenia spectrum disorder and bipolar disorder.

The ratio of physical multimorbidity was about four times higher in younger populations with SMI (mean age ≤ 40; OR, 3.99; 95% CI, 1.43-11.10) than in older populations (mean age > 40; OR, 1.55; 95% CI, 0.96-2.51; subgroup differences, P = .0013).

In terms of absolute prevalence, 25% of those with SMI had a physical multimorbidity, and 14% had a psychiatric multimorbidity, which were primarily anxiety and substance use disorders.

Investigators speculated that physical multimorbidity in SMI could stem from side effects of psychotropic medications, which are known to cause rapid cardiometabolic changes, including weight gain. In addition, lifestyle factors or nonmodifiable risk factors could also contribute to physical multimorbidity.

The study’s limitations included its small sample sizes for subgroup analyses and insufficient analysis for significant covariates, including smoking rates and symptom severity.

“While health services and treatment guidelines often operate on the assumption that individuals have a single principal diagnosis, these results attest to the clinical complexity many people with severe mental illness face in relation to burden of chronic disease,” the investigators wrote. They added that a greater understanding of the epidemiological manifestations of multimorbidity in SMI is “imperative.”

There was no source of funding for this study. Dr. Halstead is supported by the Australian Research Training Program scholarship. Other disclosures were noted in the original article.

VIENNA — With the glucagon-like peptide (GLP) 1 receptor agonist semaglutide (Wegovy) recently shown to significantly induce weight loss in people with osteoarthritis (OA) and obesity in the STEP-9 trial, could drugs traditionally used to treat type 2 diabetes be the next big thing for OA management?

“Hormone-based weight loss drugs are a game changer” for obesity management, Sébastien Czernichow, MD, PhD, said during a plenary session at the OARSI 2024 World Congress.

Sara Freeman/Medscape Medical News

Drugs such as semaglutide may also have a cardioprotective effect, reducing the risk for major adverse cardiovascular events by as much as 20% vs placebo, added Dr. Czernichow, professor of nutrition at Paris Cité University and head of the Department of Nutrition at the George Pompidou European Hospital in Paris, France.

“You have to keep in mind that the short-term side effects are mainly gastrointestinal and [are] manageable. The mid-term side effects are an increased gallbladder [disease] risk, and the long-term benefits and risks are not really well known yet,” Dr. Czernichow said. With regard to that, the effects of these drugs on lean body mass, bone health, and nutritional deficiencies need to be further evaluated and monitored.
 

Weight Loss Benefits

Weight loss is one of the cornerstones of OA management, and in addition to the weight loss seen with the GLP-1 receptor agonists, there have also been changes in body composition, Dr. Czernichow said.

In SURMOUNT-1, for example, the dual glucose-dependent insulinotropic polypeptide and GLP-1 receptor agonist tirzepatide (Zepbound) was shown to significantly reduce total fat mass with a smaller decrease in total lean mass in a subanalysis.

It has been argued that effects on body composition need to be considered when evaluating new weight loss drugs, and that focusing only on the degree of weight reduction is “encouraging inaccurate measures of medication efficacy for both patients and clinicians,” Dr. Czernichow said, citing a viewpoint published in JAMA Internal Medicine.

“The real question is: Are we able to fund these drugs for everyone? Or will only the richest patients be allocated to these drugs?” Dr. Czernichow said.
 

Weight Rebound

Tonia Vincent, MBBS, PhD, professor of musculoskeletal biology and an honorary rheumatologist at The Kennedy Institute of Rheumatology at University of Oxford in England, was concerned about rebound weight gain.

“We hear a lot about this, that people stopping drugs actually get worse weight gain than before they started, and that’s a concern about a drug that is going to have a huge pressure for supply,” Dr. Vincent said following Dr. Czernichow’s presentation.

Another delegate said that calling GLP-1 receptor agonists a “game changer” for weight loss in OA was premature because long-term results are needed.

“You mentioned that the double-digit weight loss is getting very close to the results from bariatric surgery, but bariatric surgery you do once, and for these drugs, to maintain the weight loss, you need to take them continuously,” she said.
 

Weight Loss Affects Bone

Yet another delegate cautioned on the potential effects of significant weight loss on bone and cartilage. There is evidence, he said, that weight loss of 5-10 kg can significantly affect bone turnover, increasing bone resorption and thus putting patients at a risk of becoming osteopenic. “Are we looking at a new population of osteoporosis patients who may then also be at risk for fractures?” he asked.

Separately at OARSI 2024, Anne C. Bay-Jensen, PhD, chief technology officer at Nordic Bioscience in Herlev, Denmark, and colleagues reported data showing that weight loss was associated with an increase in bone and cartilage degradation.

Although Dr. Bay-Jensen and colleagues found that losing weight was associated with improved patient outcomes, there was a 1.58-fold increase in the bone resorption marker CTX-I in people who had lost weight vs a 1.37-fold gain in those whose weight remained stable and 1.11-fold increase in those who gained weight.

Moreover, there was a 1.15-fold increase in the cartilage degradation marker C2M in the weight loss group and 0.84-fold decrease in the interstitial matrix degradation marker C3M.
 

GLP-1 and Bone Effects

Another question is whether GLP-1 receptor agonists might be having direct effects on the bone that may be beneficial in OA. They might, postdoctoral researcher Eda Çiftci, PhD, of AO Research Institute Davos in Switzerland, and collaborators, said during the poster sessions at OARSI 2024.

Dr. Çiftci and researchers reported the findings of an in vitro study that looked at whether liraglutide might have anti-inflammatory and anabolic effects on a human chondrocytes model that had been treated with interleukin (IL)-1-beta to “mimic an inflammatory OA condition.”

The release of the proinflammatory cytokines IL-6 and IL-8 was reduced by treatment with liraglutide when compared with control chondrocytes. Furthermore, the expression of the proteoglycan aggrecan — important for articular cartilage function — also was preserved.

These results suggest that liraglutide does indeed have anabolic and anti-inflammatory effects, Dr. Çiftci and fellow researchers concluded.
 

New Role for Dipeptidyl Transferase Inhibitors?

Researchers are also looking at the potential role for other diabetes medications in OA management, including the dipeptidyl peptidase (DPP) 4 inhibitors.

Although these drugs are considered “weight neutral,” in vitro studies have suggested that the DPP4 enzyme may have a role to play in chondrocyte survival and inflammation, Yu-Hsiu Chen, MD, of the Tri-Service General Hospital and the National Defense Medical Center in Taipei, Taiwan, told this news organization. The DPP4 enzyme inactivates GLP-1, so there is rationale there.

“Last year, we published a paper where we found the concentration of DPP4 in the synovial fluid was correlated with radiographic change in knee OA,” Dr. Chen said. This time, “we’re trying to see if a DPP4 inhibitor can be used as a treatment.”

For their analysis, they used data on people newly diagnosed with type 2 diabetes who were and were not using DPP4 inhibitors obtained from Taiwan’s National Health Insurance Research Database. This database contains information on 99% of the Taiwanese population, Dr. Chen said.

Matching 165,333 DPP4 inhibitor users with an equal number of nonusers showed that there was a significant 58% risk reduction for developing OA with DPP4 inhibitor use (hazard ratio, 0.42; 95% CI, 0.41-0.44).

DPP4 inhibitor use was also associated with a 58% risk lower risk for total knee replacement (TKR) and a 62% lower risk for total hip replacement.

Dr. Chen and colleagues concluded: “These results strongly indicate that DPP4 inhibitors could be considered as a viable treatment approach for individuals with type 2 [diabetes mellitus] who are at risk for developing OA or [who] already have OA.”
 

Could Sodium-Glucose Cotransporter 2 (SGLT2) Inhibitors Be Beneficial?

So, what about SGLT2 inhibitors? Do they also have a potential role to play in managing people with OA, regardless of whether there is diabetes present? Perhaps, and their effect may be even greater than what’s been observed for GLP-1 receptor agonists, as data presented by epidemiologist S. Reza Jafarzadeh, DVM, PhD, suggested.

“While GLP-1 receptor agonist drugs have been reported to reduce OA risk, largely attributed to their weight loss effect, SGLT2 inhibitors may provide a greater protective effect on OA outcomes,” said Dr. Jafarzadeh, assistant professor at Boston University.

The congress was sponsored by the Osteoarthritis Research Society International.

Dr. Czernichow disclosed ties with BariaTek Medical, Boehringer Ingelheim, Bristol Myers Squibb, Fresenius, Janssen, Jellynov, Lilly, Novo Nordisk, Novartis, and ViiV Healthcare. Dr. Vincent had no relevant disclosures. Dr. Bay-Jensen is the chief technology officer and director of immunoscience at Nordic Bioscience, which funded the work in the poster she presented at OARSI 2024. The work presented by Dr. Çiftci and colleagues was funded by the Eurostars-2 joint program with co-funding from the European Horizon 2020 research and innovation program. Dr. Çiftci had no personal disclosures to report. Dr. Chen’s work was supported by the government of Taiwan, and she had no financial conflicts of interest to disclose. Dr. Jafarzadeh had no conflicts of interest to disclose.

Moreover, there was a 1.15-fold increase in the cartilage degradation marker C2M in the weight loss group and 0.84-fold decrease in the interstitial matrix degradation marker C3M.
 

GLP-1 and Bone Effects

Another question is whether GLP-1 receptor agonists might be having direct effects on the bone that may be beneficial in OA. They might, postdoctoral researcher Eda Çiftci, PhD, of AO Research Institute Davos in Switzerland, and collaborators, said during the poster sessions at OARSI 2024.

Dr. Çiftci and researchers reported the findings of an in vitro study that looked at whether liraglutide might have anti-inflammatory and anabolic effects on a human chondrocytes model that had been treated with interleukin (IL)-1-beta to “mimic an inflammatory OA condition.”

The release of the proinflammatory cytokines IL-6 and IL-8 was reduced by treatment with liraglutide when compared with control chondrocytes. Furthermore, the expression of the proteoglycan aggrecan — important for articular cartilage function — also was preserved.

These results suggest that liraglutide does indeed have anabolic and anti-inflammatory effects, Dr. Çiftci and fellow researchers concluded.
 

New Role for Dipeptidyl Transferase Inhibitors?

Researchers are also looking at the potential role for other diabetes medications in OA management, including the dipeptidyl peptidase (DPP) 4 inhibitors.

Although these drugs are considered “weight neutral,” in vitro studies have suggested that the DPP4 enzyme may have a role to play in chondrocyte survival and inflammation, Yu-Hsiu Chen, MD, of the Tri-Service General Hospital and the National Defense Medical Center in Taipei, Taiwan, told this news organization. The DPP4 enzyme inactivates GLP-1, so there is rationale there.

“Last year, we published a paper where we found the concentration of DPP4 in the synovial fluid was correlated with radiographic change in knee OA,” Dr. Chen said. This time, “we’re trying to see if a DPP4 inhibitor can be used as a treatment.”

For their analysis, they used data on people newly diagnosed with type 2 diabetes who were and were not using DPP4 inhibitors obtained from Taiwan’s National Health Insurance Research Database. This database contains information on 99% of the Taiwanese population, Dr. Chen said.

Matching 165,333 DPP4 inhibitor users with an equal number of nonusers showed that there was a significant 58% risk reduction for developing OA with DPP4 inhibitor use (hazard ratio, 0.42; 95% CI, 0.41-0.44).

DPP4 inhibitor use was also associated with a 58% risk lower risk for total knee replacement (TKR) and a 62% lower risk for total hip replacement.

Dr. Chen and colleagues concluded: “These results strongly indicate that DPP4 inhibitors could be considered as a viable treatment approach for individuals with type 2 [diabetes mellitus] who are at risk for developing OA or [who] already have OA.”
 

Could Sodium-Glucose Cotransporter 2 (SGLT2) Inhibitors Be Beneficial?

So, what about SGLT2 inhibitors? Do they also have a potential role to play in managing people with OA, regardless of whether there is diabetes present? Perhaps, and their effect may be even greater than what’s been observed for GLP-1 receptor agonists, as data presented by epidemiologist S. Reza Jafarzadeh, DVM, PhD, suggested.

“While GLP-1 receptor agonist drugs have been reported to reduce OA risk, largely attributed to their weight loss effect, SGLT2 inhibitors may provide a greater protective effect on OA outcomes,” said Dr. Jafarzadeh, assistant professor at Boston University.

VIENNA — With the glucagon-like peptide (GLP) 1 receptor agonist semaglutide (Wegovy) recently shown to significantly induce weight loss in people with osteoarthritis (OA) and obesity in the STEP-9 trial, could drugs traditionally used to treat type 2 diabetes be the next big thing for OA management?

“Hormone-based weight loss drugs are a game changer” for obesity management, Sébastien Czernichow, MD, PhD, said during a plenary session at the OARSI 2024 World Congress.

Sara Freeman/Medscape Medical News

Drugs such as semaglutide may also have a cardioprotective effect, reducing the risk for major adverse cardiovascular events by as much as 20% vs placebo, added Dr. Czernichow, professor of nutrition at Paris Cité University and head of the Department of Nutrition at the George Pompidou European Hospital in Paris, France.

“You have to keep in mind that the short-term side effects are mainly gastrointestinal and [are] manageable. The mid-term side effects are an increased gallbladder [disease] risk, and the long-term benefits and risks are not really well known yet,” Dr. Czernichow said. With regard to that, the effects of these drugs on lean body mass, bone health, and nutritional deficiencies need to be further evaluated and monitored.
 

Weight Loss Benefits

Weight loss is one of the cornerstones of OA management, and in addition to the weight loss seen with the GLP-1 receptor agonists, there have also been changes in body composition, Dr. Czernichow said.

In SURMOUNT-1, for example, the dual glucose-dependent insulinotropic polypeptide and GLP-1 receptor agonist tirzepatide (Zepbound) was shown to significantly reduce total fat mass with a smaller decrease in total lean mass in a subanalysis.

It has been argued that effects on body composition need to be considered when evaluating new weight loss drugs, and that focusing only on the degree of weight reduction is “encouraging inaccurate measures of medication efficacy for both patients and clinicians,” Dr. Czernichow said, citing a viewpoint published in JAMA Internal Medicine.

“The real question is: Are we able to fund these drugs for everyone? Or will only the richest patients be allocated to these drugs?” Dr. Czernichow said.
 

Weight Rebound

Tonia Vincent, MBBS, PhD, professor of musculoskeletal biology and an honorary rheumatologist at The Kennedy Institute of Rheumatology at University of Oxford in England, was concerned about rebound weight gain.

“We hear a lot about this, that people stopping drugs actually get worse weight gain than before they started, and that’s a concern about a drug that is going to have a huge pressure for supply,” Dr. Vincent said following Dr. Czernichow’s presentation.

Another delegate said that calling GLP-1 receptor agonists a “game changer” for weight loss in OA was premature because long-term results are needed.

“You mentioned that the double-digit weight loss is getting very close to the results from bariatric surgery, but bariatric surgery you do once, and for these drugs, to maintain the weight loss, you need to take them continuously,” she said.
 

Weight Loss Affects Bone

Yet another delegate cautioned on the potential effects of significant weight loss on bone and cartilage. There is evidence, he said, that weight loss of 5-10 kg can significantly affect bone turnover, increasing bone resorption and thus putting patients at a risk of becoming osteopenic. “Are we looking at a new population of osteoporosis patients who may then also be at risk for fractures?” he asked.

Separately at OARSI 2024, Anne C. Bay-Jensen, PhD, chief technology officer at Nordic Bioscience in Herlev, Denmark, and colleagues reported data showing that weight loss was associated with an increase in bone and cartilage degradation.

Although Dr. Bay-Jensen and colleagues found that losing weight was associated with improved patient outcomes, there was a 1.58-fold increase in the bone resorption marker CTX-I in people who had lost weight vs a 1.37-fold gain in those whose weight remained stable and 1.11-fold increase in those who gained weight.

DENVER — In addition to the established gastrointestinal side effects common with the highly effective anti-obesity drugs, there is growing discussion around their potential to contribute to the loss of lean mass, necessary to keep the metabolic engine running full-steam.

And although measures should be recommended to prevent those effects, experts also want to remind clinicians that the loss of lean mass is indeed expected with most weight loss interventions — when they’re successful.

“The bottom line is if you’re successful with weight loss, it’s a normal process that you’re going to lose some lean mass,” Angela Fitch, MD, associate director of the Massachusetts General Hospital Weight Center in Boston, said during a presentation on the issue at Obesity Medicine 2024.

“It’s what we would expect to see if you successfully lost weight with bariatric surgery or with an intense lifestyle intervention,” said Dr. Fitch, past president of the Obesity Medicine Association.

“The difference is, there haven’t been nearly as many people being successful with weight loss with those other interventions,” she noted. “But with the popularity of the glucagon-like peptide 1 (GLP-1) medications, people are hearing this for the first time and saying, ‘Oh my gosh, 30% of the weight loss is muscle mass — that’s horrible.’ “

An underlying goal in the treatment of obesity is the reduction of fat mass, and significant fat mass reduction can provide benefits exceeding the drawbacks resulting from lean mass loss, which have been reported in clinical trials of the GLP-1s semaglutide and the dual glucose-dependent insulinotropic polypeptide tirzepatide to range from about 25% to 40%, respectively, of weight loss.

“Excess adiposity is what makes us sick — not our weight,” Dr. Fitch underscored. “The amount of fat that people are losing [with anti-obesity medications] is far more beneficial than maybe the potential that they’ve lost a little bit of lean mass,” she said.

She cited research suggesting that significant weight loss from bariatric surgery is linked to increases in life expectancy, cardiovascular risk reduction, cancer risk reduction, and a wide array of other positive effects — despite the loss of lean mass that occurs with the weight loss.

Opportunity for Awareness

The increased attention on issues of body composition accompanying weight loss importantly provides clinicians the chance to underscore to patients the importance of offsetting the loss of lean mass through strength training, nutritional choices, and other measures.

However, patients should be prepared that achieving these goals can be more challenging than expected, said Dr. Fitch.

“It can be very hard to be in an energy deficit (due to a weight loss regimen) and gain muscle mass,” she said. “When athletes are trying to gain muscle mass, they’re increasing their intake to do so. It doesn’t come naturally in today’s world.”

Nevertheless, patients can be reassured that the losses can be reversed with some effort, Dr. Fitch noted.

She cautioned that for those who succeed in building or rebuilding lean mass, the evidence may be reflected on the scale, with numbers going up, not down — something they may not wish to see.

“Patients tend to freak out when they see the scale going up after losing all of that weight, but you can reassure them that it’s okay — this is healthier weight gain.”

Special Considerations in Older Patients

Efforts at staving off lean mass loss are particularly important in older patients, who are already most vulnerable to experiencing it naturally with age, even if not on a weight loss regimen.

But Dr. Fitch offered that age does not necessarily have to be a barrier in tackling those effects.

She described two cases of treating patients in their mid-70s, a male and female, with GLP-1s for obesity. Not only were they able to achieve substantial reductions in body mass index over nearly a year on treatment, but they were also able to avoid skeletal muscle mass loss during a period when it would have likely naturally occurred.

She noted the need to augment strength training with protein intake to help build muscle, citing recommendations including consumption of 1.4-2.0 g of protein per kg of body weight for building muscle and maintaining muscle mass.

Importantly, “make sure patients aren’t too appetite suppressed so they can keep up with their nutrition,” Dr. Fitch said.

A key condition to watch for in these patients is sarcopenia. Definitions of sarcopenia vary, but it is distinguished by low skeletal muscle mass and either low muscle strength — measured, for instance, with hand grip — or low muscle performance, such as reduced walking speed or muscle power, Dr. Fitch said.

In such cases, patients may need special considerations, including avoiding significant caloric deficits and whether the risks of medication outweigh the benefits.

‘Super-Responders’ and Other Lean Mass Loss Scenarios

Further addressing the issues of body composition and weight loss at the meeting, Robert F. Kushner, MD, professor of medicine and medicine education at Northwestern University in Chicago, noted that one area of concern regarding lean mass loss is “super-responders” — patients who have exceptionally high weight loss on GLP-1s.

“We are concerned about individuals who experience very high weight loss responses to medication, [specifically] 25% or more weight loss, as well as individuals at higher risk of losing lean body mass [muscle mass], specifically people in their 50s, 60s, and 70s,” Dr. Kushner told this news organization.

“Lifestyle counseling, particularly regarding safety and body composition, is recommended in these patients,” he said, adding that in managing these patients, “the approach is to use close patient monitoring, dose reduction if needed, and emphasizing a high-protein diet accompanied by aerobic and resistance physical activity.”

Potentially dramatic lean mass loss can occur in obesity whether or not patients are on obesity medications. As evidence of this, Dr. Kushner cited a subanalysis of the Look AHEAD trial of 1019 overweight or obese patients who had a mean age of 58 years at baseline. Patients were randomized to either a physical activity and reduced calorie intervention group or simply education.

Although the results showed that fat losses in the intervention group were generally regained over 8 years, a striking, steady decline was observed in lean mass in both the intervention and control groups, including men and women.

Dr. Fitch disclosed ties to Eli Lilly, Novo Nordisk, Currax, Vivus, SideKick Health, Jenny Craig, Carmot, and Seca. Dr. Kushner is on the advisory boards of Novo Nordisk, Weight Watchers, Lilly, Boehringer Ingelheim, and Altimmune.

TOPLINE:

Nearly 90% of adults were at risk of developing cardiovascular-kidney-metabolic (CKM) syndrome between 2011 and 2020, according to new research published in JAMA.

METHODOLOGY:

• In 2023, the American Heart Association defined  to acknowledge how heart and kidney diseases, diabetes, and obesity interact and are increasingly co-occurring conditions.
• Researchers used data from the National Health and Nutrition Examination Survey between 2011 and 2020.
• More than 10,000 adults over age 20 years were included; all of them received a physical and fasting laboratory measurements and self-reported their cardiovascular disease (CVD) status.
• Researchers created categories for risk, ranging from 0 (no risk factors) to 4, using factors such as kidney disease, obesity, and hypertension.

TAKEAWAY:

• Nearly 90% of participants met the criteria for having a stage of the CKM syndrome, with rates remaining steady throughout the study period.Almost half of people met the criteria for stage 2 (having metabolic risk factors like hypertension or moderate- to high-risk chronic kidney disease).
• 14.6% met the criteria for advanced stage 3 (very high-risk chronic kidney disease or a high risk for 10-year CVD) and stage 4 CKM syndrome (established CVD) combined.
• Men, adults over age 65 years, and Black individuals were at a greater risk for advanced stages of the CKM syndrome.
• Almost half of people met the criteria for stage 2 (having metabolic risk factors like hypertension or moderate- to high-risk chronic kidney disease).
   
• 14.6% met the criteria for advanced stage 3 (very high-risk chronic kidney disease or a high risk for 10-year CVD) and stage 4 CKM syndrome (established CVD) combined.
   
• Men, adults over age 65 years, and Black individuals were at a greater risk for advanced stages of the CKM syndrome.

IN PRACTICE:

“Equitable health care approaches prioritizing CKM health are urgently needed,” the study authors wrote.

TOPLINE:

Nearly 90% of adults were at risk of developing cardiovascular-kidney-metabolic (CKM) syndrome between 2011 and 2020, according to new research published in JAMA.

METHODOLOGY:

• In 2023, the American Heart Association defined  to acknowledge how heart and kidney diseases, diabetes, and obesity interact and are increasingly co-occurring conditions.
• Researchers used data from the National Health and Nutrition Examination Survey between 2011 and 2020.
• More than 10,000 adults over age 20 years were included; all of them received a physical and fasting laboratory measurements and self-reported their cardiovascular disease (CVD) status.
• Researchers created categories for risk, ranging from 0 (no risk factors) to 4, using factors such as kidney disease, obesity, and hypertension.

TAKEAWAY:

• Nearly 90% of participants met the criteria for having a stage of the CKM syndrome, with rates remaining steady throughout the study period.Almost half of people met the criteria for stage 2 (having metabolic risk factors like hypertension or moderate- to high-risk chronic kidney disease).
• 14.6% met the criteria for advanced stage 3 (very high-risk chronic kidney disease or a high risk for 10-year CVD) and stage 4 CKM syndrome (established CVD) combined.
• Men, adults over age 65 years, and Black individuals were at a greater risk for advanced stages of the CKM syndrome.
• Almost half of people met the criteria for stage 2 (having metabolic risk factors like hypertension or moderate- to high-risk chronic kidney disease).
   
• 14.6% met the criteria for advanced stage 3 (very high-risk chronic kidney disease or a high risk for 10-year CVD) and stage 4 CKM syndrome (established CVD) combined.
   
• Men, adults over age 65 years, and Black individuals were at a greater risk for advanced stages of the CKM syndrome.

IN PRACTICE:

“Equitable health care approaches prioritizing CKM health are urgently needed,” the study authors wrote.

CHICAGO — The diabetes/weight loss drug semaglutide is associated with a significantly greater risk for repeat operations in patients with diabetes who require lumbar surgery, a new study suggests.

The risk for additional surgeries was even higher among patients taking the popular weight loss and diabetes drug for longer periods of time.

Investigators say the study provides the first evidence on the impact of semaglutide on spine surgery. 

“The expectation was [that] we would see patients doing better after surgery, less wound complications, and other things, and in our diabetic patients we did not see that and saw increased odds of needing additional surgeries,” investigator Syed I. Khalid, MD, neurosurgery resident at University of Illinois Chicago, told this news organization.

The findings were presented on May 3 at the American Association of Neurological Surgeons (AANS) 2024 Annual Meeting.
 

Additional Surgery at Year 1

The new study used the all-payer Mariner database to identify patients aged 18-74 years with type 2 diabetes who underwent elective one- to three-level transforaminal lumbar interbody fusions (TLIFs) between January 2018 and October 2022. 

Patients were matched in a 3:1 ratio for age, sex, hypertension, obesity, smoking history, chronic kidney disease, osteoporosis, insulin use, and spinal fusion level, resulting in 447 patients with semaglutide use and 1334 with no semaglutide use. More than half (56%) were female, 62% used insulin, and 81% underwent single-level TLIF.

Total medical complications were higher in the semaglutide group, at 13.4%, compared with 7.7% in the no-semaglutide group (odds ratio [OR], 1.85). This was driven by higher rates of urinary tract infection (6.7% vs 2.5%) and acute kidney injury (6.3% vs 3.9%), two complications observed with semaglutide in other studies, Dr. Khalid said.

Total surgical complications, however, were lower in patients taking semaglutide, at 3.8% vs 5.2% in those who did not (OR, 0.73). 

Patients taking semaglutide vs those who were not using semaglutide had fewer wound healing complications (5 vs 31), hematoma (1 vs 9), surgical-site infections (12 vs 44), and cerebrospinal fluid leaks (2 vs 3).

Still, people taking semaglutide were nearly 12 times more likely to have an additional lumbar surgery at 1 year than did those who did not use the drug (27.3% vs 3.1%; OR, 11.79; 95% CI, 8.17-17.33).

Kaplan-Meier plots revealed a striking divergence of these populations when semaglutide exposure for more than or less than 9 months was examined (log-rank P < .0001).

Currently under review for publication, this study provides the first evidence on the impact of semaglutide on spine surgery, Dr. Khalid said. A second follow-up paper, also under review, looked only at patients with patients morbidly obesity without diabetes who had taken semaglutide for weight loss. 

“In nondiabetic, morbidly obese patients undergoing spine surgery, we see a similar trend,” Dr. Khalid said.
 

Sarcopenia the Cause?

The additional surgeries were primarily extensions of constructs, with additional surgery and fusion at more levels, Dr. Khalid noted. 

“The idea is that it could be the fact there is sarcopenia or muscle loss that’s taking place in conjunction with fat loss that’s causing that to happen,” Dr. Khalid said.

The mechanism remains speculative, but evidence from other areas examining frailty states has shown that those patients have weaker bones, sarcopenia, and worse outcomes with spine surgery, he noted. 

The investigators plan to use artificial intelligence to evaluate changes in body composition after semaglutide use in patients who underwent imaging prior to spine surgery or even before back pain occurred. Because these medications are uptitrated over time, follow-up studies will also look at whether this change takes place with a certain dose, Dr. Khalid added. 

On the basis of the current analysis of generic semaglutide alone, it’s not possible to say whether the use of other glucagon-like peptide 1 (GLP-1) receptor agonists will result in similar findings, but “the odds of a class effect are high,” Dr. Khalid said. 

Commenting on the findings, Walavan Sivakumar, MD, director of neurosurgery at Pacific Neuroscience Institute, Los Angeles, noted that the timing of surgery is already an issue for patients taking semaglutide and other GLP-1 receptor agonists following recent guidance from the American Society of Anesthesiologists that suggests stopping GLP-1 receptor agonists prior to elective surgery to reduce the risk for complications associated with anesthesia.

“It’s an incredibly topical point and seems to be something showing up on a daily basis for clinicians all throughout neurosurgery,” Dr. Sivakumar said. “It’s thought-provoking and a great first start.” 

Dr. Sivakumar also observed that frailty is a hot topic in all of neurosurgery. “That’s a major, major point that’s showing an impact on all surgical outcomes and it’s being heavily studied in the neurosurgical subsets right now. So that’s definitely a possible correlating factor.”

Dr. Khalid reported no financial relationships. Dr. Sivakumar reported serving as a consultant for Stryker.

Pharmaceutical giant Eli Lilly recently announced that its newly approved weight loss medication Zepbound — a glucagon-like peptide 1 receptor agonist (GLP-1 RA) akin to Mounjaro, Ozempic, and Wegovy — will be prescribed by independent telehealth providers on a platform managed by the company itself. The drug can be subsequently shipped direct to consumer (DTC), allowing delivery straight to patients’ homes. 

This arrangement raises serious concerns about an inherent conflict of interest, as we previously discussed. What happens when a pharmaceutical company influences access to remote providers who prescribe the very medications it manufactures? Will these remote providers truly put the patient’s interest first when debating their safety and appropriate use? Whom will patients consult if they have concerns after initiating the medication?

Without new guardrails, the potential for misleading messaging to result in dangerous prescribing patterns looms large. The United States is one of only two countries to allow DTC advertising of prescription drugs, and the explosion in demand for GLP-1 RAs is partly attributable to this model (Oh, oh, Ozempic, anyone?). Americans spent over $78 billion on weight loss goods and services in 2019; time-intensive approaches such as diet and exercise are understandably difficult, and the public has always looked for a magic cure. Although GLP-1 RAs are promising, they may present a path to disaster without proper supervision.

LillyDirect, which in addition to Zepbound offers migraine medications and other products in the company’s catalogue, primarily aims to increase access to medication and reduce costs of the drugs for consumers. The stated mission is noble: By cutting out the middlemen of traditional pharmacies and benefit managers, administrative costs drop. LillyDirect goes a step further by reducing the need for patients to visit their regular family doctor to receive these medications.

On the surface, this design appears promising. Wait times for doctor’s appointments will fall. Patients can order drugs from the comfort of their home. Everyone benefits. Or do they? 

Although easier access and reduced cost may be an apparent win for patients, DTC arrangements complicate the ethics of prescriptions and patient follow-up. This model reminds us of the roots of the opioid crisis, where powerful advertising and relationships between prescribers and drugmakers led to great harm. Providers often faced a conflict of interest when prescribing dangerous drugs to patients who requested them. We must learn from these mistakes to ensure there is critical oversight into the independence of prescribers used by LillyDirect and other DTC platforms.

Adding to these parallels, once a patient begins a GLP-1 medication such as Zepbound, stopping treatment will probably lead to regaining lost weight, serving as negative reinforcement. Hence, patients may decide never to discontinue these medications.

Obtaining what amounts to a lifelong prescription from a telehealth provider who may never follow a patient sets a dangerous precedent that will be difficult to unravel once begun. Recent challenges in access to medications such as Zepbound have been complicated by supply chain and manufacturing issues, leading to potential interruptions in patient access, ultimately affecting compliance. The rapid increase in online providers indicates competition for distribution channels has sharply increased and poses a threat to Lilly’s DTC site. 

Furthermore, the lack of a regular physician to monitor patients introduces uncertainty in safety and continuity of care. These are important tenets in protecting patients, especially patients who are not diabetic and desire a quick fix. We have already seen a huge, arguably unrestrained, rise in prescriptions of GLP-1 RAs for weight loss — up to a 352% increase in 2023.

These drugs have shown great promise and are generally safe when used in the right patient, but important contraindications exist — namely, serious gastrointestinal side effects and low blood glucose in nondiabetic persons — that an astute physician must consider. Patients desiring these medications often must undergo comprehensive laboratory testing and cardiac evaluation, both before initiation and during regular follow-up, to check for comorbidities.

The American College of Physicians cautioned against such prescribing practices in a recent position statement, emphasizing that the lack of an established care provider could adversely affect patients. We note that the potential harms of DTC sales would concentrate in economically and racially underserved communities, where obesity, lack of insurance, and low health literacy are more common. 

But the DTC genie is out of the pill bottle, and as such platforms become more common, patients will inherently take more ownership over their medical care. Remote providers will of course not be following these patients and evaluating for side effects. As a result, we in medical practice must be abreast of new downsides of these medications if and when they arise. 

Every clinician must be aware of the medications a patient is taking, even those that they did not prescribe. They should educate their patients about drug-drug interactions and side effects and order lab tests to monitor for side effects. 

Independent physicians abide by an underlying oath: First, do no harm. They serve as a trusted check on industry and a valuable long-term partner for patients. Where are the guardrails to protect patients and ensure that pharmaceutical companies are not essentially pushing prescriptions for their own products? Will traditional healthcare providers be effectively relegated to a bystander role in Lilly’s transactional approach to medication distribution? Unlike other commercial goods, pharmacologics have great nuance; not every approved medication is meant for every patient.

Although easier access and reduced cost may be an apparent win for patients, DTC arrangements complicate the ethics of prescriptions and patient follow-up. This model reminds us of the roots of the opioid crisis, where powerful advertising and relationships between prescribers and drugmakers led to great harm. Providers often faced a conflict of interest when prescribing dangerous drugs to patients who requested them. We must learn from these mistakes to ensure there is critical oversight into the independence of prescribers used by LillyDirect and other DTC platforms.

Adding to these parallels, once a patient begins a GLP-1 medication such as Zepbound, stopping treatment will probably lead to regaining lost weight, serving as negative reinforcement. Hence, patients may decide never to discontinue these medications.

Obtaining what amounts to a lifelong prescription from a telehealth provider who may never follow a patient sets a dangerous precedent that will be difficult to unravel once begun. Recent challenges in access to medications such as Zepbound have been complicated by supply chain and manufacturing issues, leading to potential interruptions in patient access, ultimately affecting compliance. The rapid increase in online providers indicates competition for distribution channels has sharply increased and poses a threat to Lilly’s DTC site. 

Furthermore, the lack of a regular physician to monitor patients introduces uncertainty in safety and continuity of care. These are important tenets in protecting patients, especially patients who are not diabetic and desire a quick fix. We have already seen a huge, arguably unrestrained, rise in prescriptions of GLP-1 RAs for weight loss — up to a 352% increase in 2023.

These drugs have shown great promise and are generally safe when used in the right patient, but important contraindications exist — namely, serious gastrointestinal side effects and low blood glucose in nondiabetic persons — that an astute physician must consider. Patients desiring these medications often must undergo comprehensive laboratory testing and cardiac evaluation, both before initiation and during regular follow-up, to check for comorbidities.

The American College of Physicians cautioned against such prescribing practices in a recent position statement, emphasizing that the lack of an established care provider could adversely affect patients. We note that the potential harms of DTC sales would concentrate in economically and racially underserved communities, where obesity, lack of insurance, and low health literacy are more common. 

But the DTC genie is out of the pill bottle, and as such platforms become more common, patients will inherently take more ownership over their medical care. Remote providers will of course not be following these patients and evaluating for side effects. As a result, we in medical practice must be abreast of new downsides of these medications if and when they arise. 

Every clinician must be aware of the medications a patient is taking, even those that they did not prescribe. They should educate their patients about drug-drug interactions and side effects and order lab tests to monitor for side effects. 

Independent physicians abide by an underlying oath: First, do no harm. They serve as a trusted check on industry and a valuable long-term partner for patients. Where are the guardrails to protect patients and ensure that pharmaceutical companies are not essentially pushing prescriptions for their own products? Will traditional healthcare providers be effectively relegated to a bystander role in Lilly’s transactional approach to medication distribution? Unlike other commercial goods, pharmacologics have great nuance; not every approved medication is meant for every patient.
