Diabetes

HAMBURG, Germany – Use of some antibiotic and antipsychotic drugs increases the risk of sudden cardiac arrest (SCA) among people with type 2 diabetes who do not have a history of cardiovascular disease (CVD), shows the first such analysis of real-world, primary care data.

People with type 2 diabetes who do not have a history of CVD have almost three times the risk of SCA if they take antipsychotic medications and nearly double the risk if they take certain antibiotics that prolong the QT interval, notably, macrolides and fluoroquinolones.

“These data show that commonly prescribed drugs - antipsychotic medications, used by about 3% of people with type 2 diabetes, and antibiotics, taken by 5% to 10%, convey an increased risk of sudden cardiac arrest in those without a history of cardiovascular disease,” said Peter Harms, MSc, who presented the study at the annual meeting of the European Association for the Study of Diabetes. Another drug associated with an increase in SCA among patients with diabetes was domperidone, an antinausea medication.

“Perhaps these drugs could be avoided in some cases, and GPs should be more aware of the possible consequences of their use,” he added. “If the patient has type 2 diabetes, then maybe it’s better to avoid some of these medications and try and cope without them, or at least find an alternative antibiotic.”

Mr. Harms, an epidemiologist from Amsterdam University Medical Centers, highlighted that their study was unique because the investigators drew upon primary care data. “These data are extensive, and we find a lot of associations which are very real.”

SCA is associated with 50% of all cardiac deaths and accounts for 20% of all mortality in high-income countries. Of those people who experience SCA, 80% of cases prove fatal.

“As the name suggests, it is difficult to predict because it is sudden, especially in people without a cardiovascular disease history,” Mr. Harms pointed out in an interview with this news organization. He highlighted that “around half of those who experience SCA, often between the ages of 40 and 60 years, have never seen a cardiologist, but many do have type 2 diabetes.

“We need to better understand how to recognize people at risk of SCA, know who to watch and how to prevent these events,” he emphasized.

Vladimira Fejfarova, MD, comoderated the session and commented on the study. “From the clinical point of view, it’s necessary to evaluate risk factors that can contribute to sudden cardiac arrest.”

Overall, the researchers found that, among people with type 2 diabetes who do not have a history of CVD, hypoglycemia, severe hypertension, dyslipidemia, and use of QTc-prolonging medications are associated with SCA risk. Among people with type 2 diabetes and CVD, albuminuria and heart failure are associated with SCA risk.

Dr. Fejfarova added: “With type 2 diabetes and also type 1, we need to look more at adverse events, especially when treating infections with macrolides, but also mycotic infections, because antimycotic drugs are known to influence QT intervals that could contribute to sudden cardiac arrest.

“We need to be more cautious with prescribing certain antibiotics that have these side effects in our patients with diabetes,” asserted Dr. Fejfarova, from the Diabetes Centre, Institute for Clinical and Experimental Medicine, Prague.
 

Type 2 diabetes doubles the risk of SCA

The researcher decided to investigate the population of people with type 2 diabetes because their risk of SCD is around twice that of those without type 2 diabetes. Because these patients have relatively frequent checkups with general practitioners, Mr. Harms turned to primary care databases that contained comprehensive and relatively routine information on risk indicators.

Longitudinal associations between clinical characteristics of 3,919 patients with type 2 diabetes – both those with and those without a history of CVD – and SCA (a total of 689 patients) were determined.

Cases were found in the AmsteRdam REsuscitation STtudies (ARREST) registry of out-of-hospital resuscitation attempts by emergency medical services in the Dutch region of Noord-Holland from 2010 to 2019. Case patients were matched with up to five control patients. The control group comprised people with type 2 diabetes who had not experienced an SCA. Control patients were sourced from the same primary care practices who were of similar age and sex. Clinical measurements, including blood pressure and blood glucose readings, medication use, and medical history for the 5 years leading up to an SCA, were obtained from general practice records. A multivariable analysis was performed, and results were stratified for people with and for those without a history of CVD.

Of particular interest were drugs that interfere with cardiac function, including some prokinetic, antibiotic, and antipsychotic medications. All of the drugs are known to be associated with a change in QTc prolongation. Examples include domperidone (QTc-prolonging prokinetic), macrolides and fluoroquinolones (QTc-prolonging antibiotics), and haloperidol (a QTc-prolonging antipsychotic).
 

Antibiotic and antipsychotic use might contribute to SCA in T2D

Case patients and control patients were similar in age, hemoglobin A1c level, and other characteristics with the exception that more patients with SCA had a history of CVD (40.0% vs. 29.4%).

“Looking at the associations in the overall population, insulin use was strongly associated with SCA risk [hazard ratio, 2.38] and perhaps this was an indicator of severity of type 2 diabetes,” remarked Mr. Harms. “Also, unsurprisingly, a history of arrhythmia [HR, 1.68] and, more surprisingly, prokinetic drug use [HR, 1.66; 95% confidence interval, 1.20-2.31], specifically those known for QTc-prolongation, were associated with SCA.”

Among people who had experienced an SCA and who did not have a history of CVD (337 case patients/2,023 control patients), QTc-prolonging antipsychotic medication use was associated with SCA at an HR of 2.87, and antibiotic medication use was associated with SCA at an HR of 1.66. A low fasting glucose level (< 4.5 mmol/mol) was associated with SCA at an HR of 2.5; severely high systolic blood pressure (> 180 mm Hg) was associated with SCA at an HR of 2.21; low HDL cholesterol level, with an HR of 1.35; and high LDL cholesterol level (> 2.6 mmol/L), with an HR of 1.64.

Among people with a history of CVD (352 case patients/1,207 control patients), associations between albuminuria and SCA were moderate (HR, 1.54) and severe (HR, 1.55); heart failure was associated with SCA at an HR of 1.85 (95% CI, 1.50-2.29).

Comoderator Dr. Fejfarova added that, in addition to the findings from Dr. Harms’ study, other research presented in the same session highlighted the importance of checking patients for the presence of arrhythmias that could lead to the development of atrioventricular blocks, sinus node diseases, and SCA.

Mr. Harms and Dr. Fejfarova have disclosed no relevant financial relationships.

VANCOUVER – In patients with type 2 diabetes, sodium-glucose cotransporter 2 (SGLT2) inhibitors as an adjunct to metformin were not associated with an increase in fracture risk, according to a new real-world study.

There have been some reports of an increase in fracture risk associated with SGLT2 inhibitors, and it was observed in the phase 3 CANVAS trial of canagliflozin (Invokana), which led to a Food and Drug Administration warning of fracture risks associated with canagliflozin use. Some ensuing studies did not show an increased risk, but these studies were generally less than a year in duration and may have missed longer-term risk, according to Veerle van Hulten, MSc.

“Fracture risk is something that takes a long time to develop, so we wanted to have a longer follow-up. We looked into the CPRD [Clinical Practice Research Datalink], which is a beautiful database containing real-world data from primary care practices,” said Ms. van Hulten, a PhD student at Maastricht (the Netherlands) University, who presented the study at the annual meeting of the American Society for Bone and Mineral Research.

Ms. van Hulten and colleagues compared SGLT2 inhibitors with dipeptidyl peptidase–4 (DPP-4) inhibitors because the latter are used in similar populations and have been shown to have no effect on fracture risk.

“What we found is that SGLT2 inhibitors are not associated with an increased fracture risk. Even with a duration of use of over 811 days, we did not observe an increased hazard ratio for fractures when compared DPP-4 inhibitor users,” Ms. van Hulten said.

SGLT2 inhibitors reduce blood sugar by increasing elimination of sugar in the urine. They also increase phosphate, reduce calcium, and increase parathyroid hormone, which could in turn negatively affect bone turnover, according to Ms. van Hulten.

In the new study, conducted between January 2013 and June 2020, the researchers used propensity score matching to compare adult patients, including 13,807 who were prescribed SGLT2 inhibitors and 28,524 who were prescribed DPP-4 inhibitors for the first time. They matched patients based on demographics, comorbidities, comedication, and lifestyle factors.

There was no association between SGLT2 inhibitor use and overall fracture risk or major osteoporotic, hip, vertebral, humerus, radius, or ulna fractures. There was no difference in risk for any duration of use, even with the longest duration of use of 811 days (adjusted hazard ratio, 1.0). There were no differences among specific SGLT2 inhibitors, including canagliflozin (aHR, 1.12; 95% confidence interval, 0.73-1.72). Analyses by sex and age also revealed no statistically significant differences between the two drug classes.

During the Q&A session after the presentation, Sarah Berry, MD, MPH, an associate professor of medicine at Harvard Medical School and a clinical researcher at the Marcus Institute for Aging Research, both in Boston, noted the trend toward an increase in fracture risk in the first 90 days. “It looked like there was something going on in the first 90 days, and then after that the results were much closer to the null. I would put out maybe another potential mechanism whereby the SGLT2 inhibitors might cause fracture, and that’s falls. They cause polyuria, and any drug you give that causes women to rush to the bathroom may well cause fractures, particularly in the short term,” Dr. Berry said.

Ms. van Hulten agreed, and also brought up that the drugs can cause osmotic diuresis. That can lead to hypovolemia, the symptoms of which include weakness, fatigue, and dizziness. “And increased falls, of course, increases fracture risk. We do not expect anything to happen to bone metabolism in the first 90 days. I think we can agree that there would be more time needed to alter the bone enough to increase fracture risk, so we expect that this trend toward an increased risk might be attributable to that increased fall risk that might occur with SGLT2 inhibitor use,” she said.

It’s possible that such a mechanism explains increased fracture risk seen in some earlier short-term studies, she added.

Overall, Ms. van Hulten said that the results should provide some confidence in SGLT2 inhibitors, though more work needs to be done. “I think we provide reassurance that SGLT2 inhibitors are safe to use. However, we still only have a median follow-up of 1.6 years. It’s not as long as we maybe would like, but it’s the best we can do with the data available, since the SGLT2 inhibitors have only been used since 2013. So maybe it’s best to prescribe it and keep [fall risk] in mind and look into the effects later on again, but it seems to be safe to use.”

The study received funding from the Novo Nordisk Foundation. Ms. van Hulten and Dr. Berry reported no relevant financial relationships.

Ms. van Hulten agreed, and also brought up that the drugs can cause osmotic diuresis. That can lead to hypovolemia, the symptoms of which include weakness, fatigue, and dizziness. “And increased falls, of course, increases fracture risk. We do not expect anything to happen to bone metabolism in the first 90 days. I think we can agree that there would be more time needed to alter the bone enough to increase fracture risk, so we expect that this trend toward an increased risk might be attributable to that increased fall risk that might occur with SGLT2 inhibitor use,” she said.

It’s possible that such a mechanism explains increased fracture risk seen in some earlier short-term studies, she added.

Overall, Ms. van Hulten said that the results should provide some confidence in SGLT2 inhibitors, though more work needs to be done. “I think we provide reassurance that SGLT2 inhibitors are safe to use. However, we still only have a median follow-up of 1.6 years. It’s not as long as we maybe would like, but it’s the best we can do with the data available, since the SGLT2 inhibitors have only been used since 2013. So maybe it’s best to prescribe it and keep [fall risk] in mind and look into the effects later on again, but it seems to be safe to use.”

The study received funding from the Novo Nordisk Foundation. Ms. van Hulten and Dr. Berry reported no relevant financial relationships.

In 2021, diabetes and related complications was the 8th leading cause of death in the United States.¹ As of 2022, more than 11% of the U.S. population had diabetes and 38% of the adult U.S. population had prediabetes.² Diabetes is the most expensive chronic condition in the United States, where $1 of every $4 in health care costs is spent on care.³

Where this is most concerning is diabetes in pregnancy. While childbirth rates in the United States have decreased since the 2007 high of 4.32 million births⁴ to 3.66 million in 2021,⁵ the incidence of diabetes in pregnancy – both pregestational and gestational – has increased. The rate of pregestational diabetes in 2021 was 10.9 per 1,000 births, a 27% increase from 2016 (8.6 per 1,000).⁶ The percentage of those giving birth who also were diagnosed with gestational diabetes mellitus (GDM) was 8.3% in 2021, up from 6.0% in 2016.⁷

Diabetes in pregnancy not only increases risks of adverse events for mother and fetus: Increasing research suggests the condition signals longer-term risks for the mother and child throughout their lifetimes. Adverse outcomes for an infant born to a mother with diabetes include a higher risk of obesity and diabetes as adults, potentially leading to a forward-feeding cycle.

We and our colleagues established the Diabetes in Pregnancy Study Group of North America in 1997 because we had witnessed too frequently the devastating diabetes-induced pregnancy complications in our patients. The mission we set forth was to provide a forum for dialogue among maternal-fetal medicine subspecialists. The three main goals we set forth to support this mission were to provide a catalyst for research, contribute to the creation and refinement of medical policies, and influence professional practices in diabetes in pregnancy.⁸

In the last quarter century, DPSG-NA, through its annual and biennial meetings, has brought together several hundred practitioners that include physicians, nurses, statisticians, researchers, nutritionists, and allied health professionals, among others. As a group, it has improved the detection and management of diabetes in pregnant women and their offspring through knowledge sharing and influencing policies on GDM screening, diagnosis, management, and treatment. Our members have shown that preconceptional counseling for women with diabetes can significantly reduce congenital malformation and perinatal mortality compared with those women with pregestational diabetes who receive no counseling.^9,10

We have addressed a wide variety of topics including the paucity of data in determining the timing of delivery for women with diabetes and the Institute of Medicine/National Academy of Medicine recommendations of gestational weight gain and risks of not adhering to them. We have learned about new scientific discoveries that reveal underlying mechanisms to diabetes-related birth defects and potential therapeutic targets; and we have discussed the health literacy requirements, ethics, and opportunities for lifestyle intervention.^11-16

But we need to do more.

Two risk factors are at play: Women continue to choose to have babies at later ages and their pregnancies continue to be complicated by the rising incidence of obesity (see Figure 1 and Figure 2).

Dr. Reece and Dr. Miodovnik

The global obesity epidemic has become a significant concern for all aspects of health and particularly for diabetes in pregnancy.

Dr. Reece and Dr. Miodovnik

In 1990, 24.9% of women in the United States were obese; in 2010, 35.8%; and now more than 41%. Some experts project that by 2030 more than 80% of women in the United States will be overweight or obese.²¹

If we are to stop this cycle of diabetes begets more diabetes, now more than ever we need to come together and accelerate the research and education around the diabetes in pregnancy. Join us at this year’s DPSG-NA meeting Oct. 26-28 to take part in the knowledge sharing, discussions, and planning. More information can be found online at https://events.dpsg-na.com/home.

Patients with obesity but without major depressive disorder or suicidal ideation within the previous 2 years attained meaningful weight loss with semaglutide, regardless of antidepressant use at baseline, in a post hoc analysis of the Semaglutide Treatment Effect in People with Obesity (STEP) program.

Adverse events, including psychiatric events, were slightly more usual in the patients on antidepressants, Robert Kushner, MD, noted, in an oral session at the annual meeting of the Obesity Society.  

“It is very common that patients who present for weight management are taking antidepressants for various reasons, including depression, anxiety, insomnia, or chronic pain,”Dr. Kushner, from Northwestern University in Chicago, said in an email. “We wanted to see if these participants responded differently to semaglutide, compared to those not on antidepressants.”

“We found that antidepressants do not blunt the effect of semaglutide for weight loss,” he said. “However, there is a slight increase in reported adverse effects.”

“Semaglutide 2.4 mg provides an effective treatment option for weight management, regardless of antidepressant use at baseline,” Dr. Kushner summarized. “Clinicians should be assured that we can use semaglutide in this population of patients.”

Jack Yanovski, MD, PhD, said this was a “great presentation,” noting that “it’s really important that we understand what goes on in patients with depression.”

“Of course, all these trials still had rules that prevent the folks with the most severe depressive symptoms or past suicidality to participate,” added Dr. Yanovski, chief of the Growth and Obesity Section, Eunice Kennedy Shriver National Institute of Child Health and Human Development, Rockville, Md. “We need specific trials to know exactly how well we do.”

Dr. Kushner agreed, but also noted that, ever since some earlier antidepressants were associated with risk for suicidal ideation and death, strict guidelines were put in place that exclude certain patients from participating in clinical trials.

Dr. Yanovski suggested that now that the drugs are approved, it would be possible to study this, and the information would be important for clinicians.

Dr. Kushner said he hopes that such studies are forthcoming. In the meantime, “data like this will add some support and understanding,” he suggested.
 

36,000 Patients with obesity, 500 on antidepressants

Many people living with obesity report taking antidepressants for depression, anxiety, chronic pain, obsessive-compulsive disorder, sleep disturbance, neuropathy, panic disorder, or posttraumatic stress disorder, Dr. Kushner noted.

However, some of these medications can cause weight gain, and little is known about treatment outcomes for people with obesity who are on antidepressants, since most weight-loss studies exclude people with active major depressive disorder.

The researchers analyzed data from 1,961 patients in STEP 1 and 807 patients in STEP 2 as well as 611 patients in STEP 3 and 304 patients in STEP 5 – 3,683 participants in total, of which 539 were on antidepressants at baseline.

The patients were randomly assigned to 2.4 mg semaglutide vs. placebo plus a lifestyle intervention (STEP 1, 2, and 5) or intensive behavioral therapy (STEP 3 only), for 68 weeks, except STEP 5, which was 104 weeks.

Patients were included if they were aged 18 or older with a body mass index ≥30 kg/m², or ≥27 kg/m² with more than one weight-related complication (STEP 1, 3, and 5) or BMI ≥27 kg/m² with type 2 diabetes (STEP 2 only), and at least one self-reported unsuccessful effort to lose weight by diet.

They were excluded if they had active major depressive disorder within 2 years prior to screening (or other severe psychiatric disorders such as schizophrenia or bipolar disorder) or a Patient Health Questionnaire-9 score of 15 or higher (indicating moderately severe or severe depression), or suicide ideation (type 4 or 5 on the Columbia Suicide Severity Rating Scale) or suicide behavior, within 30 days of screening.

From baseline to week 68, patients on semaglutide (with/without baseline antidepressant use) had a significantly greater change in weight vs. patients on placebo (with/without baseline antidepressant use), respectively:

• STEP 1: –15.7% / –14.7% vs. –0.2% / –2.8%
• STEP 2: –10.7% / –9.5% vs. –3.3% / –3.4%
• STEP 3: –16.2% / –15.9% vs. –5.0% / –5.9%
• STEP 5: –19.0% / –14.1% vs. +1.6% / – 4.0%. 

The proportion of reported adverse events was generally slightly greater in patients receiving semaglutide (with/without baseline antidepressant use) than those on placebo (with/without baseline antidepressant use), respectively:

• STEP 1: 97.7% vs 88.6% and 92.9% vs. 86%
• STEP 2: 97.6% vs 86.5% and 88.6% vs. 77.2%
• STEP 3: 97.6% vs 95.3% and 100% vs. 95.8%
• STEP 5: 100% vs 94.8% and 95.5% vs. 89.2%.

Gastrointestinal adverse events were more frequently reported in the semaglutide group and in patients on antidepressants at baseline. The proportion of patients with psychiatric adverse events was greater in participants on antidepressants at baseline. There were no differences in suicidal ideation/behavior in patients with/without antidepressant use at baseline.

The STEP trials were funded by Novo Nordisk. Dr. Kushner discloses that he served as a consultant for Novo Nordisk, WeightWatchers, Eli Lilly, and Pfizer, and received a research grant from Epitomee.

Patients with obesity but without major depressive disorder or suicidal ideation within the previous 2 years attained meaningful weight loss with semaglutide, regardless of antidepressant use at baseline, in a post hoc analysis of the Semaglutide Treatment Effect in People with Obesity (STEP) program.

Adverse events, including psychiatric events, were slightly more usual in the patients on antidepressants, Robert Kushner, MD, noted, in an oral session at the annual meeting of the Obesity Society.  

“It is very common that patients who present for weight management are taking antidepressants for various reasons, including depression, anxiety, insomnia, or chronic pain,”Dr. Kushner, from Northwestern University in Chicago, said in an email. “We wanted to see if these participants responded differently to semaglutide, compared to those not on antidepressants.”

“We found that antidepressants do not blunt the effect of semaglutide for weight loss,” he said. “However, there is a slight increase in reported adverse effects.”

“Semaglutide 2.4 mg provides an effective treatment option for weight management, regardless of antidepressant use at baseline,” Dr. Kushner summarized. “Clinicians should be assured that we can use semaglutide in this population of patients.”

Jack Yanovski, MD, PhD, said this was a “great presentation,” noting that “it’s really important that we understand what goes on in patients with depression.”

“Of course, all these trials still had rules that prevent the folks with the most severe depressive symptoms or past suicidality to participate,” added Dr. Yanovski, chief of the Growth and Obesity Section, Eunice Kennedy Shriver National Institute of Child Health and Human Development, Rockville, Md. “We need specific trials to know exactly how well we do.”

Dr. Kushner agreed, but also noted that, ever since some earlier antidepressants were associated with risk for suicidal ideation and death, strict guidelines were put in place that exclude certain patients from participating in clinical trials.

Dr. Yanovski suggested that now that the drugs are approved, it would be possible to study this, and the information would be important for clinicians.

Dr. Kushner said he hopes that such studies are forthcoming. In the meantime, “data like this will add some support and understanding,” he suggested.
 

36,000 Patients with obesity, 500 on antidepressants

Many people living with obesity report taking antidepressants for depression, anxiety, chronic pain, obsessive-compulsive disorder, sleep disturbance, neuropathy, panic disorder, or posttraumatic stress disorder, Dr. Kushner noted.

However, some of these medications can cause weight gain, and little is known about treatment outcomes for people with obesity who are on antidepressants, since most weight-loss studies exclude people with active major depressive disorder.

For women who are obese, daily life is wrought with landmines. Whether it’s the challenges of air travel because plane seats are too small, the need to shield themselves from the world’s discriminating eyes, or the great lengths many will go to achieve better health and the promise of longevity, navigating life as an obese person requires a thick skin.

So, it’s no wonder so many are willing to pay more than $1,000 a month out of pocket to get their hands on drugs like semaglutide (Ozempic and Wegovy) or tirzepatide (Mounjaro). The benefits of these drugs, which are part of a new class called glucagonlike peptide–1 (GLP-1) receptor agonists, include significant and rapid weight loss, blood sugar control, and improved life quality; they are unprecedented in a setting where surgery has long been considered the most effective long-term option.

On the flip side, the desire for rapid weight loss and better blood sugar control also comes with an unexpected cost. Many women living with obesity who take oral contraceptives are unaware that these drugs – especially Mounjaro – can interfere with the absorption of birth control pills and how well they work, making an unintended pregnancy more likely.

Neel Shah, MD, an endocrinologist and associate professor at the University of Texas Health Science Center at Houston, said he has had several patients become pregnant without intending to. 

“It was when Mounjaro came out on the market when we started using it,” he said of the drug the Food and Drug Administration approved for type 2 diabetes in 2022. “It [the warning] was in the product insert, but clinically speaking, I don’t know if it was at the top of providers’ minds when they were prescribing Mounjaro.”

When asked if he believed that we were going to be seeing a significant increase in so-called Mounjaro babies, Dr. Shah was sure in his response. 

“Absolutely. We will because the sheer volume [of patients] will increase,” he said.
 

It’s all in the gut

One of the ways that drugs like Mounjaro work is by delaying the time that it takes for food to move from the stomach to the small intestine. Although data are still evolving, it is believed that this process – delayed gastric emptying – may affect the absorption of birth control pills. 

Dr. Shah said another theory is that vomiting, which is a common side effect of these types of drugs, also affects the pills’ ability to prevent pregnancy. 

And “there’s a prolonged period of ramping up the dose because of the GI side effects,” said Pinar Kodaman, MD, PhD, a reproductive endocrinologist and assistant professor of gynecology at Yale University in New Haven, Conn. 

“Initially, at the lowest dose, there may not be a lot of potential effect on absorption and gastric emptying. But as the dose goes up, it becomes more common, and it can cause diarrhea, which is another condition that can affect the absorption of any medication,” she said.
 

Unanticipated outcomes, extra prevention

Roughly 42% of women in the United States are obese, 40% of whom are between the ages of 20 and 39. Although these new drugs can improve fertility outcomes for women who are obese (especially those with polycystic ovary syndrome, or PCOS), only one – Mounjaro – currently carries a warning about birth control pill effectiveness on its label. Unfortunately, it appears that some doctors are unaware or not counseling patients about this risk, and the data are unclear about whether other drugs in this class, like Ozempic and Wegovy, have the same risks. 

“To date, it hasn’t been a typical thing that we counsel about,” said Dr. Kodaman. “It’s all fairly new, but when we have patients on birth control pills, we do review other medications that they are on because some can affect efficacy, and it’s something to keep in mind.”

It’s also unclear if other forms of birth control – for example, birth control patches that deliver through the skin – might carry similar pregnancy risks. Dr. Shah said some of his patients who became pregnant without intending to were using these patches. This raises even more questions, since they deliver drugs through the skin directly into the bloodstream and not through the GI system. 

What can women do to help ensure that they don’t become pregnant while using these drugs? 

“I really think that if patients want to protect themselves from an unplanned pregnancy, that as soon as they start the GLP receptor agonists, it wouldn’t be a bad idea to use condoms, because the onset of action is pretty quick,” said Dr. Kodaman, noting also that “at the lowest dose there may not be a lot of potential effect on gastric emptying. But as the dose goes up, it becomes much more common or can cause diarrhea.” 

Dr. Shah said that in his practice he’s “been telling patients to add barrier contraception” 4 weeks before they start their first dose “and at any dose adjustment.”

Zoobia Chaudhry, an obesity medicine doctor and assistant professor of medicine at Johns Hopkins University in Baltimore, recommends that “patients just make sure that the injection and medication that they take are at least 1 hour apart.”

“Most of the time, patients do take birth control before bedtime, so if the two are spaced, it should be OK,” she said.

Another option is for women to speak to their doctors about other contraceptive options like IUDs or implantable rods, where gastric absorption is not going to be an issue. 

“There’s very little research on this class of drugs,” said Emily Goodstein, a 40-year-old small-business owner in Washington, who recently switched from Ozempic to Mounjaro. “Being a person who lives in a larger body is such a horrifying experience because of the way that the world discriminates against you.”

She appreciates the feeling of being proactive that these new drugs grant. It has “opened up a bunch of opportunities for me to be seen as a full individual by the medical establishment,” she said. “I was willing to take the risk, knowing that I would be on these drugs for the rest of my life.”

In addition to being what Dr. Goodstein refers to as a guinea pig, she said she made sure that her primary care doctor was aware that she was not trying or planning to become pregnant again. (She has a 3-year-old child.) Still, her doctor mentioned only the most common side effects linked to these drugs, like nausea, vomiting, and diarrhea, and did not mention the risk of pregnancy.

“Folks are really not talking about the reproductive implications,” she said, referring to members of a Facebook group on these drugs that she belongs to. 

Like patients themselves, many doctors are just beginning to get their arms around these agents. “Awareness, education, provider involvement, and having a multidisciplinary team could help patients achieve the goals that they set out for themselves,” said Dr. Shah. 

Clear conversations are key.

In addition to being what Dr. Goodstein refers to as a guinea pig, she said she made sure that her primary care doctor was aware that she was not trying or planning to become pregnant again. (She has a 3-year-old child.) Still, her doctor mentioned only the most common side effects linked to these drugs, like nausea, vomiting, and diarrhea, and did not mention the risk of pregnancy.

“Folks are really not talking about the reproductive implications,” she said, referring to members of a Facebook group on these drugs that she belongs to. 

Like patients themselves, many doctors are just beginning to get their arms around these agents. “Awareness, education, provider involvement, and having a multidisciplinary team could help patients achieve the goals that they set out for themselves,” said Dr. Shah. 

Clear conversations are key.

HAMBURG, GERMANY – Testosterone replacement therapy was associated with significant reductions in hemoglobin A1c at 1 and 2 years among men with type 2 diabetes, a multinational audit shows.

“If you have a patient with type 2 diabetes, sexual dysfunction, or fatigue, please consider checking their testosterone level. And if they fulfill criteria for testosterone deficiency and have had their [prostate-specific antigen] checked, consider a trial of treatment and follow them,” study lead author T. Hugh Jones, MD, consultant physician and endocrinologist at Barnsley (England) Hospital NHS Foundation Trust advised, speaking with this news organization.

Dr. Jones also urges clinicians worldwide to enter their patients’ data into the ABCD Testosterone Audit, which aims to identify long-term outcomes and predictors of response to testosterone replacement therapy.

Dr. Jones, who is also professor of andrology at the University of Sheffield, presented the preliminary data analysis at the annual meeting of the European Association for the Study of Diabetes.

Thus far, a total of 428 men with type 2 diabetes and hypogonadism are entered into the audit, from 34 centers in eight countries: the United Kingdom, Germany, Canada, Brazil, South Africa, New Zealand, Malaysia, and Vietnam. Among 121 of the men at 12 months, there was a drop in A1c from a baseline level of 71.27 mmol/mol (8.7%) to 61.26 mmol/mol (7.8%). Among 104 men at 24 months, the drop was from 71.4 mmol/mol (8.7%) to 55.97 mmol/mol (7.3%). Both decreases were significant (P < .001).

Prior data from Dr. Jones’ group showed that about 40% of men with type 2 diabetes have symptomatic testosterone deficiency. Testosterone deficiency is also associated with adverse effects on cardiovascular risk factors, bone health, muscle strength, sexual function, and psychological well-being, yet it is often overlooked, Dr. Jones noted.

“It’s not typically measured in routine clinical practice. ... Deficiency is very common, but a lot of practitioners don’t treat it and don’t ask about it. But in fact, treatment has very significant benefits for patients. ... We know from sildenafil (Viagra) studies that 60%of people who didn’t respond were testosterone deficient. After being given testosterone, they converted to Viagra responders,” he noted.

Regarding safety concerns, the recent findings from the TRAVERSE study, in which about 70% of participants had type 2 diabetes, demonstrated no increased cardiovascular risk. There was also no association with prostate cancer, although it’s important to monitor prostate-specific antigen in patients for the first year on testosterone replacement, Dr. Jones said.

Asked to comment, endocrinologist Bradley D. Anawalt, MD, chief of medicine at the University of Washington Medical Center, Seattle, told this news organization, “This ‘worldwide survey’ confirms many studies from around the world over the past 20 years. ... [T]he association is due to ‘reverse causation,’ in that diabetes type 2 and obesity lower testosterone concentrations. Weight loss of 5%-10% may raise testosterone concentrations in men with high body mass indices, large waist circumferences, and low blood testosterone concentrations.”

At the same time, Dr. Anawalt pointed to data suggesting that “[t]reatment of androgen deficiency may facilitate lifestyle measures in men with high [body mass indexes] and high risk of type 2 diabetes to prevent, or more likely delay, the development of type 2 diabetes.”

However, both Dr. Jones and Dr. Anawalt emphasized that testosterone therapy would not be expected to affect blood glucose levels or any other cardiometabolic parameters in men who are not testosterone deficient, regardless of diabetes status.

“It’s important when you give testosterone to replace it to the normal level. Adequate treatment gives the greatest benefit,”Dr. Jones said.

As more centers contribute data to the ABCD audit, Jones anticipates collecting clinical practice data on a variety of clinical parameters, including complications, total insulin dose, kidney function, and eventually cardiovascular outcomes.

In the meantime, he said, giving testosterone replacement to men with deficiency can be very rewarding for many reasons. “People feel better. Individual patients come back and say ‘thank you doctor, you’ve given me my life back.’ It’s not often you get that. And the compliance is excellent.”

Dr. Jones is a speaker for, advisory board member for, and/or travel grant recipient of Besins Healthcare, Grantss, Grunenthal, and Simple Pharma. Dr. Anawalt has no disclosures.

The prospect of remission of type 2 diabetes (T2D) has captured the hearts and minds of many patients with T2D and health care professionals, including myself.

I have changed my narrative when supporting my patients with T2D. I used to say that T2D is a progressive condition, but considering seminal recent evidence like the DiRECT trial, I now say that T2D can be a progressive condition. Through significant weight loss, patients can reverse it and achieve remission of T2D. This has given my patients hope that their T2D is no longer an inexorable condition. And hope, of course, is a powerful enabler of change.

However, the million-dollar question is whether remission of T2D can be maintained in the long term in the real-world setting of primary care, which is chiefly where T2D is managed.

I therefore relished the opportunity to attend a debate on this topic at the annual meeting of the European Association for the Study of Diabetes in Hamburg, Germany, between Roy Taylor, MD, principal investigator for the DiRECT study and professor of medicine and metabolism at the University of Newcastle, England, and Kamlesh Khunti, MD, PhD, professor of primary care diabetes at the University of Leicester, England.
 

Remarkable weight loss

Dr. Taylor powerfully recapitulated the initial results of the DiRECT study. T2D remission was achieved in 46% of participants who underwent a low-energy formula diet (around 850 calories daily) for 3-5 months. After 2 years’ follow-up, an impressive 36% of participants were still in remission. Dr. Taylor then discussed unpublished 5-year extension follow-up data of the DiRECT study. Average weight loss in the remaining intervention group was 6.1 kg. I echo Taylor’s sentiment that this finding is remarkable in the context of a dietary study.

Overall, 13% of participants were still in remission, and this cohort maintained an average weight loss of 8.9 kg. Dr. Taylor concluded that lasting remission of T2D is indeed feasible in a primary care setting.

Yet he acknowledged that although remission appears feasible in the longer term, it was not necessarily easy, or indeed possible, for everyone. He used a wonderful analogy about climbing Mount Everest: It is feasible, but not everyone can or wants to climb it. And even if you try, you might not reach the top.

This analogy perfectly encapsulates the challenges I have observed when my patients have striven for T2D remission. In my opinion, intensive weight management with a low-energy formula diet is not a panacea for T2D but another tool in our toolbox to offer patients.

He also described some “jaw-dropping” results regarding incidence of cancer: There were no cases of cancer in the intervention group during the 5-year period, but there were eight cases of cancer in the control group. The latter figure is consistent with published data for cancer incidence in patients with T2D and the body mass index (BMI) inclusion criteria for the DiRECT study (a BMI of 27-45 kg/m²). Obesity is an established risk factor for 13 types of cancer, and excess body fat entails an approximately 17% increased risk for cancer-specific mortality. This indeed is a powerful motivator to facilitate meaningful lifestyle change.

In primary care, we also need to be aware that most weight regain usually occurs secondary to a life event (for example, financial, family, or illness). We should reiterate to our patients that weight regain is not a failure; it is just part of life. Once the life event has passed, rapid weight loss can be attempted again. In the “rescue plans” that were integral to the DiRECT study, participants were offered further periods of total diet replacement, depending on quantity of weight gain. In fact, 50% of participants in DiRECT required rescue therapy, and their outcomes, reassuringly, were the same as the other 50%.

Dr. Taylor also quoted data from the ReTUNE study suggesting that weight regain was less of an issue for those with initial BMI of 21-27, and there is “more bang for your buck” in approaching remission of T2D in patients with lower BMI. The fact that people with normal or near-normal BMI can also reverse their T2D was also a game changer for my clinical practice; the concept of an individual or personal fat threshold that results in T2D offers a pragmatic explanation to patients with T2D who are frustrated by the lack of improvements in cardiometabolic parameters despite significant weight loss.

Finally, Dr. Taylor acknowledged the breadth of the definition of T2D remission: A1c < 48 mmol/mol at least 2 months off all antidiabetic medication. This definition includes A1c values within the “prediabetes” range: 42-47 mmol/mol.

He cited 10-year cardiovascular risk data driven by hypertension and dyslipidemia before significant weight loss and compared it with 10-year cardiovascular risk data after significant weight loss. Cardiovascular risk profile was more favorable after weight loss, compared with controls with prediabetes without weight loss, even though some of the intervention group who lost significant weight still had an A1c of 42-47 mmol/mol. Dr. Taylor suggested that we not label these individuals who have lost significant weight as having prediabetes. Instead “postdiabetes” should be preferred, because these patients had more favorable cardiovascular profiles.

This is a very important take-home message for primary care: prediabetes is more than just dysglycemia.
 

New terminology proposed

Dr. Khunti outlined a recent large, systematic review that concluded that the definition of T2D remission encompassed substantial heterogeneity. This heterogeneity complicates the interpretation of previous research on T2D remission and complicates the implementation of remission pathways into routine clinical practice. Furthermore, Dr. Khunti highlighted a recent consensus report on the definition and interpretation of remission in T2D that explicitly stated that the underlying pathophysiology of T2D is rarely normalized completely by interventions, thus reducing the possibility of lasting remission.

Dr. Khunti also challenged the cardiovascular benefits seen after T2D remission. Recent Danish registry data were presented, demonstrating a twofold increased risk for major adverse cardiovascular events over 5 years in individuals who achieved remission of T2D, but not on glucose-lowering drug therapy.

Adherence to strict dietary interventions in the longer term was also addressed. Diet-induced weight loss causes changes in circulating hormones such as ghrelin, glucose-dependent insulinotropic polypeptide (GIP), and leptin, which mediate appetite and drive hunger and an increased preference for energy-dense foods (that is, high-fat or sugary foods), all of which encourage weight regain. Dr. Khunti suggested that other interventions, such as glucagon-like peptide 1 (GLP-1) receptor agonists or bariatric surgery, specifically target some of these hormonal responses.

The challenges in recruitment and retention for lifestyle studies were also discussed; they reflect the challenges of behavioral programs in primary care. The DiRECT study had 20% participation of screened candidates and an attrition rate approaching 30%. The seminal Diabetes Prevention Program study and Finnish Diabetes Prevention Study had similar results. At a population level, individuals do not appear to want to participate in behavioral programs.

Dr. Khunti also warned that the review of annual care processes for diabetes is declining for patients who had achieved remission, possibly because of a false sense of reassurance among health care professionals. It is essential that all those in remission remain under at least annual follow-up, because there is still a risk for future microvascular and macrovascular complications, especially in the event of weight regain.

Dr. Khunti concluded by proposing new terminology for remission: remission of hyperglycemia or euglycemia, aiming for A1c < 48 mmol/mol with or without glucose-lowering therapy. I do agree with this; it reflects the zeitgeist of cardiorenal protective diabetes therapies and is analogous to rheumatoid arthritis, where remission is defined as no disease activity while on therapy. But one size does not fit all.

Sir William Osler’s words provide a fitting conclusion: “If it were not for the great variability among individuals, medicine might as well be a science and not an art.”

Dr. Taylor also quoted data from the ReTUNE study suggesting that weight regain was less of an issue for those with initial BMI of 21-27, and there is “more bang for your buck” in approaching remission of T2D in patients with lower BMI. The fact that people with normal or near-normal BMI can also reverse their T2D was also a game changer for my clinical practice; the concept of an individual or personal fat threshold that results in T2D offers a pragmatic explanation to patients with T2D who are frustrated by the lack of improvements in cardiometabolic parameters despite significant weight loss.

Finally, Dr. Taylor acknowledged the breadth of the definition of T2D remission: A1c < 48 mmol/mol at least 2 months off all antidiabetic medication. This definition includes A1c values within the “prediabetes” range: 42-47 mmol/mol.

He cited 10-year cardiovascular risk data driven by hypertension and dyslipidemia before significant weight loss and compared it with 10-year cardiovascular risk data after significant weight loss. Cardiovascular risk profile was more favorable after weight loss, compared with controls with prediabetes without weight loss, even though some of the intervention group who lost significant weight still had an A1c of 42-47 mmol/mol. Dr. Taylor suggested that we not label these individuals who have lost significant weight as having prediabetes. Instead “postdiabetes” should be preferred, because these patients had more favorable cardiovascular profiles.

This is a very important take-home message for primary care: prediabetes is more than just dysglycemia.
 

New terminology proposed

Dr. Khunti outlined a recent large, systematic review that concluded that the definition of T2D remission encompassed substantial heterogeneity. This heterogeneity complicates the interpretation of previous research on T2D remission and complicates the implementation of remission pathways into routine clinical practice. Furthermore, Dr. Khunti highlighted a recent consensus report on the definition and interpretation of remission in T2D that explicitly stated that the underlying pathophysiology of T2D is rarely normalized completely by interventions, thus reducing the possibility of lasting remission.

Dr. Khunti also challenged the cardiovascular benefits seen after T2D remission. Recent Danish registry data were presented, demonstrating a twofold increased risk for major adverse cardiovascular events over 5 years in individuals who achieved remission of T2D, but not on glucose-lowering drug therapy.

Adherence to strict dietary interventions in the longer term was also addressed. Diet-induced weight loss causes changes in circulating hormones such as ghrelin, glucose-dependent insulinotropic polypeptide (GIP), and leptin, which mediate appetite and drive hunger and an increased preference for energy-dense foods (that is, high-fat or sugary foods), all of which encourage weight regain. Dr. Khunti suggested that other interventions, such as glucagon-like peptide 1 (GLP-1) receptor agonists or bariatric surgery, specifically target some of these hormonal responses.

The challenges in recruitment and retention for lifestyle studies were also discussed; they reflect the challenges of behavioral programs in primary care. The DiRECT study had 20% participation of screened candidates and an attrition rate approaching 30%. The seminal Diabetes Prevention Program study and Finnish Diabetes Prevention Study had similar results. At a population level, individuals do not appear to want to participate in behavioral programs.

Dr. Khunti also warned that the review of annual care processes for diabetes is declining for patients who had achieved remission, possibly because of a false sense of reassurance among health care professionals. It is essential that all those in remission remain under at least annual follow-up, because there is still a risk for future microvascular and macrovascular complications, especially in the event of weight regain.

Dr. Khunti concluded by proposing new terminology for remission: remission of hyperglycemia or euglycemia, aiming for A1c < 48 mmol/mol with or without glucose-lowering therapy. I do agree with this; it reflects the zeitgeist of cardiorenal protective diabetes therapies and is analogous to rheumatoid arthritis, where remission is defined as no disease activity while on therapy. But one size does not fit all.

Sir William Osler’s words provide a fitting conclusion: “If it were not for the great variability among individuals, medicine might as well be a science and not an art.”

Can busy primary care offices continue to care for patients with diabetes? No one would argue that it is involved and takes effort, and health care providers are bankrupt when it comes to sparing additional time for this chronic disease. With roughly 37 million people living with diabetes and 96 million with prediabetes or early type 2 diabetes, and just over 8,000 practicing endocrinologists in the United States, we all need to make time especially in primary care to provide insight and holistic care. With limited time and budget, how do we do this?

First, decide to be involved in caring for patients with diabetes. Diabetes is best managed by interprofessional care teams, so you’re not going it alone. These teams may include physicians; pharmacists; physician assistants; advanced practice nurses; registered nurses; certified diabetes care and education specialists (CDCES); dietitians; and other professionals such as social workers, behavioral health professionals, medical assistants, and community health workers. Know which professionals are available to serve on your team, either within your clinic or as a consultant, and reach out to them to share the care and ease the burden. Remember to refer to these professionals to reinforce the diabetes intervention message to the patient.

Second, incorporate “diabetes only” appointments into your schedule, allowing time to focus on current comprehensive diabetes treatment goals, barriers/inertia for care. Remember to have short-interval follow-up as needed to keep that patient engaged to achieve their targets. Instruct your office staff to create diabetes appointment templates and reminders to patients to bring diabetes-related technologies, medication lists, and diabetes questions to the appointment. When I implemented this change, my patients welcomed the focus on their diabetes health, and they knew we were prioritizing this disease that they have for a lifetime. These appointments did not take away from their other conditions; rather, they often reminded me to stay focused on their diabetes and associated coconditions. 

Taking the time to establish efficient workflows before implementing diabetes care saves countless hours later and immediately maximizes health care provider–patient interactions. Assign specific staff duties and expectations related to diabetes appointments, such as downloading diabetes technology, medication reconciliation, laboratory data, point-of-care hemoglobin A1c, basic foot exam, and patient goals for diabetes care. This allows the prescriber to focus on the glycemic, cardiologic, renal, and metabolic goals and overcome the therapeutic inertia that plagues us all.

Incorporating diabetes-related technology into clinical practice can be a significant time-saver but requires initial onboarding. Set aside a few hours to create a technology clinic flow, and designate at least one team member to be responsible for obtaining patient data before, during, or after encounters. If possible, obtaining data ahead of the visit will enhance efficiency, allowing for meaningful discussion of blood glucose and lifestyle patterns. Diabetes technology reveals the gaps in care and enhances our ability to identify the areas where glycemic intervention is needed. In addition, it reveals the impact of food choices, activity level, stress, and medication adherence to the person living with diabetes. 

Finally, be proactive about therapeutic inertia. This is defined as a prescribers’ failure to intensify or deintensify a patient’s treatment when appropriate to do so. Causes of therapeutic inertia can be placed at the primary care physician level, including time constraints or inexperience in treating diabetes; the patient level, such as concerns about side effects or new treatment regimens; or a systemic level, such as availability of medications or their costs. Be real with yourself: We all have inertia and can identify areas to overcome. Never let inertia be traced back to you.

Not all inertia lives with the health care provider. Patients bring apprehension and concerns, have questions, and just want to share the frustrations associated with living their best life with the disease. Don’t assume that you know what your patients’ treatment barriers are; ask them. If you don’t have an answer, then note it and come up with one by the next follow-up. Remember that this is a chronic disease – a marathon, not a sprint. You don’t have to solve everything at one appointment; rather, keep the momentum going.

Let’s put this into clinical practice. For the next patient with diabetes who comes into your office, discuss with them your intention to prioritize their diabetes by having an appointment set aside to specifically focus on their individual goals and targets for their disease. Have the patient list any barriers and treatment goals they would like to review; flag your schedule to indicate it is a diabetes-only visit; and orient your staff to reconcile diabetes medications and record the patient’s last eye exam, urine albumin-to-creatinine ratio, A1c result, and blood glucose data. During this encounter, identify the patient’s personal targets for control, examine their feet, and review or order necessary laboratory metrics. Explore the patient-reported barriers and make inroads to remove or alleviate these. Advance treatment intervention, and schedule follow-up: every 4-6 weeks if the A1c is > 9%, every 2 months if it’s 7% to < 9%, and every 3-6 months if it’s < 7%. Utilize team diabetes care, such as CDCES referrals, dietitians, online resources, and community members, to help reinforce care and enhance engagement. 

We need to take steps in our clinical practice to make the necessary space to accommodate this pervasive disease affecting nearly one-third of our population. Take a moment to look up and determine what needs to be in place so that you can take care of the people in your practice with diabetes. Laying the groundwork for implementing diabetes-only appointments can be time-consuming, but establishing consistent procedures, developing efficient workflows, and clearly defining roles and responsibilities is well worth the effort. This solid foundation equips the office, health care providers, and staff to care for persons with diabetes and will be invaluable to ensure that time for this care is available in the day-to-day clinical practice.

TOPLINE:

Nearly one in five adolescents are living with prediabetes, a condition where blood glucose levels are elevated, but are not high enough for a type 2 diabetes (T2D) diagnosis. According to a new study, higher levels of nonfasting glucose and hemoglobin A1c, and worsening obesity are important predictors of progression to T2D. In addition, metformin and weight stabilization may prove to be important interventions for preventing T2D in kids.

METHODOLOGY:

• Researchers did a retrospective chart review of patient data from Vanderbilt University Medical Center Pediatric Prediabetes Clinic, Nashville, Tenn., from May 2015 to August 2022.
• The study included 552 children with prediabetes, defined as abnormal blood glucose (fasting plasma glucose [FPG] ≥ 100 mg/dL, random glucose ≥ 150 mg/dL), or hemoglobin A1c equal to or greater than 5.9%.
• Based on follow-up visits, patients were classified as having progressed to T2D, or nonprogression.
• Researchers analyzed the patients’ initial visit A1c, fasting C-peptide, 2-hour glucose, fasting glucose, and body mass index (BMI), among other baseline characteristics.

TAKEAWAY:

• Thirty-six children (6.5%) progressed to T2D during the duration of the study period.
• The average time to T2D diagnosis was much longer in patients taking metformin (43 months), compared with those not taking the prescribed medication (28 months).
• Worsening obesity was strongly associated with T2D progression – patients who progressed to T2D had a higher BMI at baseline and had continued weight gain.
• A higher baseline A1c, fasting C-peptide, and 2-hour glucose were also associated with progression to T2D.
• In the multivariable analysis, both A1c and 2-hour glucose were strong independent predictors of progression.
• Fasting plasma glucose was not associated with progression to T2D.

IN PRACTICE:

“Weight stabilization and metformin therapy could be important interventions for diabetes prevention in children,” study author Ashley H. Shoemaker, MD, MSci, a pediatric endocrinologist at Vanderbilt University Medical Center in Nashville, Tenn., said in a press release.

In addition, A1c plus a nonfasting glucose may be a feasible way to identify high-risk pediatric patients in a clinical setting.

This study was performed by Natasha Belsky, Jaclyn Tamaroff, and Ashley H. Shoemaker of the Vanderbilt University Medical Center and the Vanderbilt University School of Medicine in Nashville, Tenn. It was published October 12, 2023, in the Journal of the Endocrine Society

LIMITATIONS:

Additional patients who developed T2D may have been lost to follow-up, since the authors did not contact patients to confirm their disease status. The authors were also unable to establish racial differences in the progression to T2D because of missing data.

DISCLOSURES:

Funding for this study was provided by the National Center for Advancing Translational Sciences. One author has research contracts with Novo Nordisk and Boehringer Ingelheim.

Each additional decade of type 2 diabetes shortens lives by about 3.5 years, compared with not having diabetes, researchers estimate on the basis of data from studies conducted in 19 high-income countries.

They estimated that, among 50-year-olds, life expectancy of those diagnosed with type 2 diabetes at age 30 is 14 years shorter than that of their peers without diabetes. Among those diagnosed at age 50, life expectancy is 6 years shorter.

The study was recently published in The Lancet – Diabetes and Endocrinology.

The team analyzed data from the Emerging Risk Factors Collaboration and the UK Biobank. The data were from 97 long-term, prospective cohorts and involved 1.5 million participants who were followed for 23.1 million person-years.

“The strongest associations with earlier age at diagnosis of diabetes were for vascular (for example, myocardial infarction and stroke) and other causes of death – mainly respiratory, neurological, and infectious diseases and external causes,” they reported.

Their findings are consistent with previous studies that suggested that younger individuals who develop type 2 diabetes might have higher body mass index (BMI), blood pressure, and lipid levels and that they might experience faster deterioration in glycemic control than individuals who develop diabetes later, potentially leading to premature mortality.

Asked to comment, Anne Peters, MD, director of clinical diabetes programs at the University of Southern California, Los Angeles, who was not involved with this study, said: “We’ve long known that diabetes reduces life expectancy, and the younger you get it the more years you lose. However, this study was from a broader and larger population base than prior studies.

“In this study, the major reason for death was vascular disease, and undertreatment of cardiovascular risk factors may have occurred in the younger individuals. We also don’t know about glucose control.

“I personally think the findings show that we should treat cardiovascular risk factors more aggressively in people diagnosed with [type 2] diabetes in their 30s and 40s,” urged Dr. Peters.
 

High priority should be given to prevention globally

“Type 2 diabetes used to be seen as a disease that affected older adults, but we’re increasingly seeing people diagnosed earlier in life,” senior author Emanuele Di Angelantonio, MD, PhD, from the University of Cambridge (England), explained in a press release. “As we’ve shown, this means they are at risk of a much shorter life expectancy than they would otherwise have.”

The findings suggest that “high priority should be given to developing and implementing interventions that prevent or delay the onset of [type 2 diabetes], especially as its prevalence among younger age groups is increasing globally,” the study authors wrote.

The results “support the idea that the younger an individual is when they develop type 2 diabetes, the more damage their body accumulates from its impaired metabolism,” added co–senior author Naveed Sattar, MD, PhD, of the University of Glasgow,

Dr. Peters agreed: “People who develop type 2 diabetes at a younger age might have a different, potentially more aggressive type of type 2 diabetes and perhaps need treatment targets that are lower than people who develop type 2 diabetes when they are older.”

“The findings ... suggest that early detection of diabetes by screening followed by intensive glucose management could help prevent long-term complications from the condition,” Dr. Sattar said.

Dr. Peters added: “An issue for some is pregnancy. ... Many of the medications taken for management of CVD [cardiovascular disease] risk factors are contraindicated in pregnancy (as are many of the medications [for treating type 2 diabetes]).

“We need to be careful to risk reduce but take care of the ‘whole person,’ and if of childbearing age, consider the safest approaches to healthy management,” she emphasized.
 

Study results: Type 2 diabetes diagnosed at age 30, 40, and 50

Previous studies estimated that adults with type 2 diabetes die 6 years earlier on average in comparison with their counterparts who do not have diabetes, but it was not known how diabetes duration affects life span.

To investigate this, the team analyzed individual records from the Emerging Risk Factors Collaboration and the UK Biobank. The primary outcome was all-cause mortality. Other outcomes were deaths from CVD, cancer, and other causes.

Over a median follow-up of 12.5 years, there were 246,670 deaths: 84,443 from cardiovascular causes, 150, 972 from noncardiovascular causes, and 11,255 from unknown/ill-defined causes.

Compared with participants who did not have a history of type 2 diabetes, the hazard ratios for all-cause mortality, adjusted for age and sex, were 2.69 for participants diagnosed at age 30-39, 2.26 for those diagnosed aged 40-49, 1.84 aged 50-59, 1.57 for those aged 60-69, and 1.39 for those diagnosed 70 and older.

These hazard ratios were similar after adjusting for BMI, systolic blood pressure, and total cholesterol, but they were substantially attenuated after further adjusting for fasting glucose or hemoglobin A1c level.

Similar patterns were observed for cause-specific mortality.

“Every decade of earlier diagnosis of diabetes was associated with about 3-4 years of lower life expectancy, highlighting the need to develop and implement interventions that prevent or delay the onset of diabetes and to intensify the treatment of risk factors among young adults diagnosed with diabetes,” the researchers wrote.

Each additional decade of type 2 diabetes shortens lives by about 3.5 years, compared with not having diabetes, researchers estimate on the basis of data from studies conducted in 19 high-income countries.

They estimated that, among 50-year-olds, life expectancy of those diagnosed with type 2 diabetes at age 30 is 14 years shorter than that of their peers without diabetes. Among those diagnosed at age 50, life expectancy is 6 years shorter.

The study was recently published in The Lancet – Diabetes and Endocrinology.

The team analyzed data from the Emerging Risk Factors Collaboration and the UK Biobank. The data were from 97 long-term, prospective cohorts and involved 1.5 million participants who were followed for 23.1 million person-years.

“The strongest associations with earlier age at diagnosis of diabetes were for vascular (for example, myocardial infarction and stroke) and other causes of death – mainly respiratory, neurological, and infectious diseases and external causes,” they reported.

Their findings are consistent with previous studies that suggested that younger individuals who develop type 2 diabetes might have higher body mass index (BMI), blood pressure, and lipid levels and that they might experience faster deterioration in glycemic control than individuals who develop diabetes later, potentially leading to premature mortality.

Asked to comment, Anne Peters, MD, director of clinical diabetes programs at the University of Southern California, Los Angeles, who was not involved with this study, said: “We’ve long known that diabetes reduces life expectancy, and the younger you get it the more years you lose. However, this study was from a broader and larger population base than prior studies.

“In this study, the major reason for death was vascular disease, and undertreatment of cardiovascular risk factors may have occurred in the younger individuals. We also don’t know about glucose control.

“I personally think the findings show that we should treat cardiovascular risk factors more aggressively in people diagnosed with [type 2] diabetes in their 30s and 40s,” urged Dr. Peters.
 

High priority should be given to prevention globally

“Type 2 diabetes used to be seen as a disease that affected older adults, but we’re increasingly seeing people diagnosed earlier in life,” senior author Emanuele Di Angelantonio, MD, PhD, from the University of Cambridge (England), explained in a press release. “As we’ve shown, this means they are at risk of a much shorter life expectancy than they would otherwise have.”

The findings suggest that “high priority should be given to developing and implementing interventions that prevent or delay the onset of [type 2 diabetes], especially as its prevalence among younger age groups is increasing globally,” the study authors wrote.

The results “support the idea that the younger an individual is when they develop type 2 diabetes, the more damage their body accumulates from its impaired metabolism,” added co–senior author Naveed Sattar, MD, PhD, of the University of Glasgow,

Dr. Peters agreed: “People who develop type 2 diabetes at a younger age might have a different, potentially more aggressive type of type 2 diabetes and perhaps need treatment targets that are lower than people who develop type 2 diabetes when they are older.”

“The findings ... suggest that early detection of diabetes by screening followed by intensive glucose management could help prevent long-term complications from the condition,” Dr. Sattar said.

Dr. Peters added: “An issue for some is pregnancy. ... Many of the medications taken for management of CVD [cardiovascular disease] risk factors are contraindicated in pregnancy (as are many of the medications [for treating type 2 diabetes]).

“We need to be careful to risk reduce but take care of the ‘whole person,’ and if of childbearing age, consider the safest approaches to healthy management,” she emphasized.
