SAN DIEGO – Endoscopic sleeve gastroplasty (ESG) led to sustained weight loss and a reduction of cardiometabolic syndrome comorbidities at 5 years, according to a new retrospective analysis of prospectively collected data.

Improved cardiometabolic outcomes following bariatric surgery have been well documented, but ESG is relatively new, so its outcomes haven’t been as well described. The outcomes are encouraging, though not as good as those of bariatric surgery. “It’s still better, but only one percent of the patients undergo the surgery, even though they’re candidates,” said Donevan Westerveld, MD, who presented the study at the annual Digestive Disease Week^® (DDW).

Improvements included weight, HbA1c percentage, hypertension, and low-density lipoprotein. “I was surprised that the LDL decreased numerically, not so much HbA1c and hypertension. I knew [those] would come down with weight loss,” said Dr. Westerveld, a second-year fellow at Weill Cornell Medicine, New York.

He also called for guidelines for ESG. “Given the fact there’s an improvement of comorbid conditions, it’s something we should look at,” said Dr. Westerveld.

“It’s fascinating because it tells us two important things about endoscopic sleeve gastroplasty. One, [the benefit] in the majority of cases lasts at least 5 years. The weight loss is durable. And then it tells us that there’s improvement in all the cardiometabolic factors that matter, and those effects are seen all the way up to 5 years. So very important findings that support the benefits of the endoscopic gastroplasty in obesity and cardiometabolic risks and metabolic syndrome,” said Andres Acosta, MD, PhD, a comoderator of the session where the study was presented. He is assistant professor of medicine and a consultant in gastroenterology and hepatology at Mayo Clinic in Rochester, Minn.

The findings should also encourage more innovation. “Doing these endoscopic procedures, having successful results that hold for 5 years, opens the path for new and better procedures, so we have better weight loss,” said Dr. Acosta.

Previous work by Dr. Westerveld’s group found benefits of ESG at 12 months, including improvements in mean HbA1c levels in all patients (6.1%-5.5%; P = .05) and those with diabetes or prediabetes (6.6%-5.6%; P = .02), reduction in mean waist circumference (119.66-92.75 cm; P < .001), reduction in systolic blood pressure (129.02-122.23 mg/dL; P = .023), triglycerides (131.84-92.36 mg/dL; P = .017), and alanine aminotransferase (ALT, 32.26-20.68 mg/dL; P < .001).

In the new study, the group followed 255 patients at 1, 3, and 5 years post procedure who were treated consecutively at Weill Cornell Medicine from 2013 to 2021. Among the patients were those who had failed weight loss measures and were either not candidates for surgery or had refused surgery.

The mean age was 45.5 years, 69% were female, and the mean body mass index was 38.6. Overall, 40.3% had prediabetes or diabetes, 26.7% had hypertension, 60.8% had low-density lipoprotein (LDL) above 100 mg/dL, and 29.3% had elevated ALT. Sixty-six percent had been followed up at 1 year, 78% at 3 years, and 87% at 5 years.

Weight loss averaged 15.7% at 1 year and 15.3% at year 5, and the values were statistically significant. Among patients with diabetes and prediabetes, HbA1c percentage dropped from a baseline value of 6.4% to 5.7% at year 1, 6.1% at year 3, and 5.8% at year 5 (P < .05 for all). For all patients, the value dropped from 5.8% at baseline to 5.6% at year 1, 5.7% at year 3, and 5.4% at year 5. These changes were not statistically significant.

Systolic blood pressure went down among patients with stage 1 hypertension, from 135 mm Hg at baseline to 122 at year 1 and 121 at year 3 (P < .05 or both), but the mean value increased to 129 at year 5 and was not statistically significant. LDL among all patients declined from 136 mg/dL at baseline to 125 at year 1 (nonsignificant), 115 at year 3 (P < .05), and 109 at year 5 (P < .05). Alanine transaminase values declined from about 29 at baseline to 25 at year 1, 26 at year 3, and 24 at year 5 (P < .05 for all).

Serious adverse events were rare, occurring in just two cases (< 1%).

The study was limited by lack of a sham control, and its retrospective data may have included bias because many of the procedures were not paid for by insurance, leading to high rates of self-pay.

Many adults can achieve remission of type 2 diabetes with a primary intervention consisting of a diet that emphasizes whole, plant-based foods, according to a new publication from the American College of Lifestyle Medicine (ACLM).

The document was developed to assist clinicians treating adults with type 2 diabetes, with the goal of remission using diet as a primary intervention. A panel of 15 experts from seven societies reached consensus on 69 statements.

“A healthy diet is a foundational component of current lifestyle guidelines for treatment of type 2 diabetes, but it is often overlooked because of the lack of physician training and patient awareness,” Felice A. Caldarella, MD, president of the American Association of Clinical Endocrinology (AACE), said in a press release from ACLM.

“The consensus statements produced by this panel of experts are invaluable in bringing awareness to the value of diet for diabetes remission in addition to management,” he summarized.

The initiative was cosponsored by the Endocrine Society, endorsed by AACE, and supported by the Academy of Nutrition and Dietetics. The expert panel also included representatives from the American College of Cardiology, the American Heart Association, and the American Academy of Family Physicians. It was published in the American Journal of Lifestyle Medicine.

“I think many patients would do the challenging work of making lifestyle modifications if it meant remission of [type 2 diabetes] and sparing them the burden and cost of medications or surgery,” said Amy E. Rothberg, MD, PhD, who represented the Endocrine Society on the panel.

“By changing the course of the disease, i.e., if in remission, they are unlikely to get the complications related to [type 2 diabetes],” Dr. Rothberg, professor of nutritional sciences at the University of Michigan, Ann Arbor, told this news organization.
 

Consensus on 69 statements

The panel members used a modified Delphi process to develop the consensus statement. They identified 49 articles from the literature regarding dietary interventions in adults with type 2 diabetes. They reached consensus on 69 statements that cover seven topics: definitions and basic concepts; diet and remission of type 2 diabetes; dietary specifics and types of diets; adjuvant and alternative interventions; support, monitoring, and adherence to therapy; weight loss; and payment and policy.

Dr. Rothberg identified six key areas:

• Definition of remission: Type 2 diabetes remission is defined as A1c < 6.5% for at least 3 months with no surgery, devices, or active pharmacologic therapy for lowering blood glucose, consistent with the diabetes remission timeline published in 2021 by the American Diabetes Association. Remission does not exclude the possibility of recurrence. Remission is a realistic and achievable goal for some adults with type 2 diabetes.
• High-intensity diet, short duration of diabetes: Patients are more likely to attain remission with a high-intensity diet (e.g., high level of restrictions plus frequent patient contact or counseling) accompanied by physical activity and if the patient has had diabetes for 4 years or less. A high-fiber diet is essential.
• Fewer calories, focus on plant-based foods: Calorie reduction could be achieved by reducing food volume, portion sizes, or energy density, or by using liquid meal replacements, or by a combination of these approaches. It should mainly include whole, plant-based foods (whole grains, vegetables, legumes, fruits, nuts, and seeds) and avoid or minimize meat and other animal products, refined foods, ultra-processed foods, and foods with added fats.
• A very low energy diet as initial intervention is optional: There was consensus that this approach can achieve remission, but there was not agreement that low calorie content was essential for achieving remission, Dr. Rothberg noted.
• Beyond type 2 remission: Diet as a primary intervention can also lower the risk of cardiovascular disease and improve lipoprotein profile.
• Self-management, support, and monitoring: The group recognizes the importance of patient education and support. “This can play a vital role and should be part of any comprehensive lifestyle treatment,” said Dr. Rothberg. The diet and lifestyle strategies should be acceptable to most patients, easy to adhere to, accommodate patient preferences and values, and be culturally sensitive.

Intensive lifestyle change can equate to bariatric surgery

Also invited to comment, Yehuda Handelsman, MD, who coauthored a 2020 type 2 diabetes management algorithm by AACE and the American College of Endocrinology, and was not involved with the current initiative, agrees with the importance of lifestyle in the management of type 2 diabetes but takes issue with a few points.

Most clinicians and experts do not believe that diabetes can be reversed, as such, only controlled, noted Dr. Handelsman, medical director of the Metabolic Institute of America, Tarzana, Calif.

“We always have approached type 2 diabetes treatment with lifestyle – diet, exercise, and (as of late) sleep – as the mainstay of therapy,” he said.

However, most patients do not adhere to diet modifications by 6 months and especially by 1 year, which has led to universal recommendations to add medication to lifestyle from inception, he continued.

Most clinicians have not been trained in lifestyle modalities. And many patients with type 2 diabetes are not adherent to medications, which “led to the relative success of bariatric surgery leading to remission (at least for 3-5 years).”

“Remission, which in broad terms implies the disappearance of signs and symptoms, should be a top priority for individuals with type 2 diabetes,” the consensus statement authors wrote.

“While [bariatric surgery] can induce remission in 25% to 80% of targeted patients, it carries risk and its effectiveness wanes as subjects regain lost weight,” and “more dramatic and intensive [lifestyle] change produces remission rates equivalent to bariatric surgery,” they noted.

Need for more randomized trials

Dr. Handelsman also stressed that remission may be temporary. “Three months or 6 months cannot be a measure of success. We must have at least 1 year,” he added. “In fact, there are data to show that remission requires 3 years.”

Nevertheless, the consensus statement does highlight the importance of lifestyle in remission of diabetes, he agreed.

The expert panel also noted that patients can benefit from a healthy lifestyle, even if they do not attain remission, Dr. Rothberg pointed out. 

Moving forward, the statement concludes that “there is ... an ongoing need for additional randomized controlled trials to assess sustainable plant-based dietary interventions with whole or minimally processed foods, as a primary means of treating [type 2 diabetes] with the goal of remission, as well as factors that lead to successful patient adherence and effective dissemination and implementation of such interventions.”

This study was supported by the Lisa Wendel Memorial Foundation. Dr. Rothberg has disclosed being the medical director of  Rewind, a virtual platform created for weight control with the goal to “defeat” type 2 diabetes, and a consultant for a study for which Nestle provides product. Dr. Handelsman has disclosed receiving research grants and consultant and speaker honoraria from Amarin, Amgen, Applied Therapeutic, AstraZeneca, Bayer, Boehringer Ingelheim, Corcept, Esperion, Ionis, Mankind, Merck, Merck-Pfizer, Novartis, Novo Nordisk, Regor, Sanofi, and Vertis.

Also invited to comment, Yehuda Handelsman, MD, who coauthored a 2020 type 2 diabetes management algorithm by AACE and the American College of Endocrinology, and was not involved with the current initiative, agrees with the importance of lifestyle in the management of type 2 diabetes but takes issue with a few points.

Most clinicians and experts do not believe that diabetes can be reversed, as such, only controlled, noted Dr. Handelsman, medical director of the Metabolic Institute of America, Tarzana, Calif.

“We always have approached type 2 diabetes treatment with lifestyle – diet, exercise, and (as of late) sleep – as the mainstay of therapy,” he said.

However, most patients do not adhere to diet modifications by 6 months and especially by 1 year, which has led to universal recommendations to add medication to lifestyle from inception, he continued.

Most clinicians have not been trained in lifestyle modalities. And many patients with type 2 diabetes are not adherent to medications, which “led to the relative success of bariatric surgery leading to remission (at least for 3-5 years).”

“Remission, which in broad terms implies the disappearance of signs and symptoms, should be a top priority for individuals with type 2 diabetes,” the consensus statement authors wrote.

“While [bariatric surgery] can induce remission in 25% to 80% of targeted patients, it carries risk and its effectiveness wanes as subjects regain lost weight,” and “more dramatic and intensive [lifestyle] change produces remission rates equivalent to bariatric surgery,” they noted.

Need for more randomized trials

Dr. Handelsman also stressed that remission may be temporary. “Three months or 6 months cannot be a measure of success. We must have at least 1 year,” he added. “In fact, there are data to show that remission requires 3 years.”

Nevertheless, the consensus statement does highlight the importance of lifestyle in remission of diabetes, he agreed.

The expert panel also noted that patients can benefit from a healthy lifestyle, even if they do not attain remission, Dr. Rothberg pointed out. 

Moving forward, the statement concludes that “there is ... an ongoing need for additional randomized controlled trials to assess sustainable plant-based dietary interventions with whole or minimally processed foods, as a primary means of treating [type 2 diabetes] with the goal of remission, as well as factors that lead to successful patient adherence and effective dissemination and implementation of such interventions.”

This study was supported by the Lisa Wendel Memorial Foundation. Dr. Rothberg has disclosed being the medical director of  Rewind, a virtual platform created for weight control with the goal to “defeat” type 2 diabetes, and a consultant for a study for which Nestle provides product. Dr. Handelsman has disclosed receiving research grants and consultant and speaker honoraria from Amarin, Amgen, Applied Therapeutic, AstraZeneca, Bayer, Boehringer Ingelheim, Corcept, Esperion, Ionis, Mankind, Merck, Merck-Pfizer, Novartis, Novo Nordisk, Regor, Sanofi, and Vertis.

An intensive 1-year behavior therapy program aimed at changing a person’s response to food “cues” might help people with obesity lose a modest amount of weight, a randomized clinical trial suggests.

“Patients who are food-cue sensitive often feel out of control with their eating; they cannot resist food and/or cannot stop thinking about food,” said lead author Kerri N. Boutelle, PhD.

“Behavioral weight loss skills are not sufficient for these individuals,” so they designed this new approach, Dr. Boutelle, of the University of California, San Diego, explained in a press release.

The regulation of cues (ROC) intervention trains individuals to respond to their hunger and to resist eating highly craved foods (internal management), in contrast to behavioral weight loss programs that focus on counting calories (external management), Dr. Boutelle explained in an email.

The results of the Providing Adult Collaborative Interventions for Ideal Changes (PACIFIC) clinical trial, including follow-up out to 2 years, were published  in JAMA Network Open.

Patients in the behavioral weight loss therapy group or the combined ROC and behavioral weight loss therapy group lost more weight at 6 months than patients in the ROC group – but then they slowly regained weight (whereas patients in the ROC group did not).

At 24 months, the three groups had a similar modest weight loss, compared with a control group that did not lose weight.

“We believe these internal management strategies are more durable over time,” said Dr. Boutelle.  

However, two obesity experts, who helped develop the Canadian Adult Obesity Clinical Practice Guidelines, cautioned in emails that the intervention is very labor-intensive with less than 5% weight loss.

Four interventions

The trial was conducted at the Center for Healthy Eating and Activity Research at the University of California, San Diego, from December 2015 to December 2019.

Researchers randomized 271 adults with a mean BMI of 35 kg/m² to one of four interventions:

• Regulation of cues: Patients were not given a prescribed diet but instead were given skills to tolerate cravings and respond better to hunger or satiety cues.
• Behavioral weight loss therapy: Patients were advised to follow a balanced, calorie-deficit diet based on their weight and given related skills.
• Combined regulation of cues plus behavioral weight loss therapy.
• Control: Patients received information about nutrition and stress management plus mindfulness training and were encouraged to find social support.

Therapy was given as 26 group sessions, 90 minutes each, over 12 months, with 16 weekly sessions, four biweekly sessions, and six monthly booster sessions.

Participants were asked to take part in 150 minutes of moderate to high intensity exercise each week and aim for 10,000 steps per day. All patients except those in the control group received a pedometer.

The patients were a mean age of 46 years, 82% were women and 62% were White.

At the end of the 12-month intervention, mean BMI had dropped by –1.18 kg/m² in the ROC group and by –1.58 kg/m² and –1.56 kg/m² in the other two groups, compared with the control group, where BMI was virtually unchanged.

At 24 months follow-up, mean BMI was similar (roughly 33.5 kg/m²) in the ROC, the behavioral weight loss therapy, and the ROC plus behavioral weight loss therapy groups.

There was weight regain from 12 months in the latter two groups but not in the ROC group.
 

‘Nice study, but not practical’

“This is a nice study, but in no way is it practical,” Sean Wharton, MD, summarized.

“I think it may have difficulty finding its way into everyday practice,” said Dr. Wharton, adjunct professor at McMaster University, Hamilton, Ontario.

Also, “it does not compare ROC to pharmacotherapy,” he added, which is “quickly becoming the gold standard for obesity management. We have learned that adding intensive behavioral therapy – more visits and possibly a liquid diet as part of the weight management and some light group counseling – to pharmacotherapy does not add much.”

However, Dr. Wharton conceded that if an individual did not want, or could not take, pharmacotherapy and had access to ROC sessions, this might be a good option.

“The challenge will be offering this labor-intensive tool to 40% of Americans living with obesity,” he said.

The ROC intervention “is very different than a GP’s office that may see a patient two to three times/year max, with limited supports,” Dr. Wharton pointed out.

“It is labor-intensive, not reproducible in most places, and cannot be sustained forever. There is no evidence that the learning remains past the treatment interval. For example, 2 to 3 years later, are patients still adhering to ROC? Is weight still decreased or do they need to come to classes every month forever?”  
 

‘Modest weight loss, doubtful long-term benefits’

Similarly, Arya M. Sharma, MD, said: “While this [ROC] approach may be helpful for some individuals, given the rather modest weight loss achieved (despite considerable efforts and a cash incentive), the long-term clinical benefits remain doubtful.”

The weight loss of less than 5% over 24 months is “in the ballpark of other behavioral weight-loss interventions,” said Dr. Sharma, of the University of Edmonton, Alberta, and past scientific director of Obesity Canada.  

“I’m not convinced” about less weight regain, he added. “The difference between the groups is minimal. While this approach may well help individuals better deal with food cues, it does not change the underlying biology of weight regain.”

“This approach at best may help prevent future weight gain in susceptible individuals,” he speculated. “I would consider this more as a weight-stabilization than a weight-loss strategy.”
 

Next steps

Insurance doesn’t always cover weight loss with a mental health professional, Dr. Boutelle agreed. “However, there are eating disorder categories that also apply to many of our food-cue-sensitive patients, including binge eating,” she noted.

“We believe that ROC is an alternative model for weight loss that could be offered to patients who are interested or for whom behavioral weight loss has not been successful ... who are highly food-cue-responsive.”

The group is writing a manual about the ROC program to disseminate to other behavior therapists. They are also studying ROC in another clinical trial, Solutions for Hunger and Regulating Eating (SHARE). The ROC program is being offered at the UC San Diego Center for Healthy Eating and Activity Research, of which Dr. Boutelle is director.

The study was supported by grants from the National Institutes of Health. The researchers have reported no relevant financial relationships. Dr. Wharton has reported receiving honoraria and travel expenses and has participated in academic advisory boards for Novo Nordisk, Bausch Health, Eli Lilly, and Janssen. He is the medical director of a medical clinic specializing in weight management and diabetes. Dr. Sharma has reported receiving speakers bureau and consulting fees from Novo Nordisk, Bausch Pharmaceuticals, and AstraZeneca.

The transition from perimenopause to menopause is accompanied by a proatherogenic shift in lipids and other circulating metabolites that potentially predispose women to cardiovascular disease (CVD). Now, for the first time, a new prospective cohort study quantifies the link between hormonal shifts and these lipid changes.

However, hormone therapy (HT) somewhat mitigates the shift and may help protect menopausal women from some elevated CVD risk, the same study suggests.

“Menopause is not avoidable, but perhaps the negative metabolite shift can be diminished by lifestyle choices such as eating healthily and being physically active,” senior author Eija Laakkonen, MD, University of Jyväskylä, Finland, told this news organization in an email.

“And women should especially pay attention to the quality of dietary fats and amount of exercise [they get] to maintain cardiorespiratory fitness,” she said, adding that women should discuss the option of HT with their health care providers.

Asked to comment, JoAnn Manson, MD, of Harvard Medical School, Boston, and past president of the North American Menopause Society, said there is strong evidence that women undergo negative cardiometabolic changes during the menopausal transition.

Changes include those in body composition (an increase in visceral fat and waist circumference), as well as unfavorable shifts in the lipid profile, as reflected by increases in low-density lipoprotein cholesterol (LDL-C) and triglycerides and a decrease in high-density lipoprotein cholesterol (HDL-C).

It’s also clear from a variety of cohort studies that HT blunts menopausal-related increases in body weight, percentage of body fat, as well as visceral fat, she said.

So the new findings do seem to “parallel” those of other perimenopausal to menopausal transition studies, which include HT having “favorable effects on lipids,” Dr. Manson said. HT “lowers LDL-C and increases HDL-C, and this is especially true when it is given orally,” but even transdermal delivery has shown some benefits, she observed.
 

Shift in hormones causes 10% of lipid changes after menopause

The new study, by Jari E. Karppinen, also of the University of Jyväskylä, and colleagues, was recently published in the European Journal of Preventive Cardiology. The data are from the Estrogenic Regulation of Muscle Apoptosis (ERMA) prospective cohort study.

In total, 218 women were tracked from perimenopause through to early postmenopause, 35 of whom started HT, mostly oral preparations. The women were followed for a median of 14 months. Their mean age was 51.7 years when their hormone and metabolite profiles were first measured.

Previous studies have shown that menopause is associated with levels of metabolites that promote CVD, but this study is the first to specifically link this shift with changes in female sex hormones, the researchers stress.

“Menopause was associated with a statistically significant change in 85 metabolite measures,” Mr. Karppinen and colleagues report.

Analyses showed that the menopausal hormonal shift directly explained the change in 64 of the 85 metabolites, with effect sizes ranging from 2.1% to 11.2%. 

These included increases in LDL-C, triglycerides, and fatty acids. Analyses were adjusted for age at baseline, duration of follow-up, education level, smoking status, alcohol use, physical activity, and diet quality.

More specifically, investigators found that all apoB-containing particle counts as well as particle diameters increased over follow-up, although no change occurred in HDL particles.

They also found cholesterol concentrations in all apoB-containing lipoprotein classes to increase and triglyceride concentrations to increase in very low-density lipoprotein and HDL particles.

“These findings, including HDL triglycerides, can be interpreted as signs of poor metabolic health since, despite higher HDL-C being good for health, high HDL triglyceride levels are associated with a higher risk of coronary heart disease,” Dr. Laakkonen emphasized.

Among the 35 women who initiated HT on study enrollment, investigators did note, on exploratory analysis, increases in HDL-C and reductions in LDL-C.

“The number of women starting HT was small, and the type of HT was not controlled,” Dr. Laakkonen cautioned, however.

“Nevertheless, our observations support clinical guidelines to initiate HT early into menopause, as this timing offers the greatest cardioprotective effect,” she added.

The study was supported by the Academy of Finland. The authors and Dr. Manson have reported no relevant financial relationships. Dr. Manson is a contributor to Medscape.

“Menopause was associated with a statistically significant change in 85 metabolite measures,” Mr. Karppinen and colleagues report.

Analyses showed that the menopausal hormonal shift directly explained the change in 64 of the 85 metabolites, with effect sizes ranging from 2.1% to 11.2%. 

These included increases in LDL-C, triglycerides, and fatty acids. Analyses were adjusted for age at baseline, duration of follow-up, education level, smoking status, alcohol use, physical activity, and diet quality.

More specifically, investigators found that all apoB-containing particle counts as well as particle diameters increased over follow-up, although no change occurred in HDL particles.

They also found cholesterol concentrations in all apoB-containing lipoprotein classes to increase and triglyceride concentrations to increase in very low-density lipoprotein and HDL particles.

“These findings, including HDL triglycerides, can be interpreted as signs of poor metabolic health since, despite higher HDL-C being good for health, high HDL triglyceride levels are associated with a higher risk of coronary heart disease,” Dr. Laakkonen emphasized.

Among the 35 women who initiated HT on study enrollment, investigators did note, on exploratory analysis, increases in HDL-C and reductions in LDL-C.

“The number of women starting HT was small, and the type of HT was not controlled,” Dr. Laakkonen cautioned, however.

“Nevertheless, our observations support clinical guidelines to initiate HT early into menopause, as this timing offers the greatest cardioprotective effect,” she added.

The study was supported by the Academy of Finland. The authors and Dr. Manson have reported no relevant financial relationships. Dr. Manson is a contributor to Medscape.

A recent ISCHEMIA trial substudy is under scrutiny from surgeons for a data discrepancy, rekindling concerns about reliance on the landmark trial data in the latest coronary revascularization guidelines.

As previously reported, the main ISCHEMIA findings showed no significant benefit for an initial strategy of percutaneous coronary intervention (PCI) or coronary bypass graft surgery (CABG) over medical therapy in patients with stable moderate to severe ischemic heart disease.

The 2021 substudy by Reynolds et al. showed that coronary artery disease (CAD) severity, classified using the modified Duke Prognostic Index score, predicted 4-year mortality and myocardial infarction in the trial, whereas ischemia severity did not.

Cardiac surgeons Joseph F. Sabik III, MD, and Faisal Bakaeen, MD, however, spotted that only 40 patients are in the Duke category 6 group (three-vessel severe stenosis of at least 70% or two-vessel severe stenosis with a proximal left anterior descending lesion) in Supplemental tables 1 and 2, whereas 659 are in the main paper.

In addition, the Supplemental tables list the following:

• 659 patients in Duke group 5, not 894 as in the paper.
• 894 patients in Duke group 4, not 743 as in the paper.
• 743 patients in Duke group 3, not 179 as in the paper.

The surgeons penned a letter to Circulation early in April flagging the discrepancies, but say it was rejected April 15 because it was submitted outside the journal’s 6-week window for letters. They posted a public comment on the Remarq research platform, as advised by Circulation’s editorial office, and reached out directly to the authors and ISCHEMIA leadership.

“They just keep saying it’s a simple formatting error. Well, if it is a simple formatting error, then fix it,” Dr. Sabik, chair of surgery at University Hospitals Cleveland Medical Center, said in an interview. “But here we are now, a month later, and they still haven’t published our letter. Why? We’re the ones who identified the problem.”

Dr. Sabik said the accuracy of the data has important implications because the recent AHA/ACC/SCAI coronary revascularization guidelines used the ISCHEMIA data to downgrade the CABG recommendation for complex multivessel disease from class 1 to class 2B. Patients with a Duke 6 score are also typically the ones referred for CABG by today’s heart teams.

Several surgical societies have contested the guidelines, questioning whether the ISCHEMIA patients are truly reflective of those seen in clinical practice and questioning the decision to treat PCI and surgery as equivalent strategies to decrease ischemic events.

Dr. Bakaeen, from the Cleveland Clinic, told this news organization they don’t want a public battle over the data like the one that befell the EXCEL trial, and that it’s entirely possible the investigators might have inadvertently upgraded all the Duke score assignments by 1.

A systematic error, however, is more plausible than a formatting error, he said, because Supplemental tables 1 and 2 correspond exactly to the Duke 1 to Duke 7 sequence, suggesting the tables are correct and that the error might have occurred downstream, including in the manuscript.

The numbers should be consistent across all the ISCHEMIA manuscripts, Dr. Bakaeen added, but currently “don’t add up,” even after adjustment for different denominators, and especially for participants with left main disease.

They hope that publication of their letter, he said, will convince the authors to publicly share the data for patients in each of the seven modified Duke categories.

Lead author of the ISCHEMIA substudy, Harmony Reynolds, MD, New York (N.Y.) University Langone Health, told this news organization via email that as a result of a “formatting error in the transfer of data from the statistical output file to a Word document, data in Supplemental tables 1 and 2 were incorrect.”

She explained that they planned to present six, not seven, rows for the Duke score in the tables, collapsing the first two categories of nonobstructive disease (Duke 1-2), as they were in all other tables and figures. However, the Supplemental tables had incorrect row headings and because the Word program is designed to fill all available rows, it inserted the data from the output file into a seven-row table shell, duplicating the values for row 1 in the last row for left main disease of at least 50%.

“The data were correctly presented in the main manuscript tables and figures and in the remainder of the supplement, with a total of 659 patients in the subset with modified Duke prognostic index category 6 on coronary CT angiography,” Dr. Reynolds said.

She noted that Circulation will issue a correction. In addition, “we are in the process of preparing the data for public sharing soon. The data will include the Duke prognostic score at all levels.”

Circulation editor-in-chief Joseph A. Hill, MD, PhD, chief of cardiology at UT Southwestern Medical Center, Dallas, declined to be interviewed but confirmed via email that Dr. Bakaeen and Dr. Sabik’s letter and the correction will be published the week of May 16.

As for the delay, he said, “I received their reach-out just over 1 week ago, and per protocol, we conducted an internal evaluation of their allegations, which took a bit of time.”

People with nonalcoholic fatty liver disease (NAFLD) and a lean or healthy body mass index are at increased risk for peripheral vascular disease, stroke, and cardiovascular disease, a surprise finding from a new study reveals.

“Our team had expected to see that those with a normal BMI would have a lower prevalence of any metabolic or cardiovascular conditions,” lead researcher Karn Wijarnpreecha, MD, MPH, said during a media briefing that previewed select research for Digestive Disease Week^® (DDW) 2022. “So, we were very surprised to find this link to cardiovascular disease.”

The investigators saw this increased risk of cardiovascular disease despite this group having a lower prevalence of atherosclerotic risk factors and metabolic disease.

This first study of its kind suggests physicians should consider the risk of cardiovascular disease in all patients with NAFLD, not just in those who are overweight or living with obesity – groups traditionally thought to carry more risk.

NAFLD in lean individuals is not a benign disease.

“NAFLD patients with a normal BMI are often overlooked because we assume that the risk for more serious conditions is lower than for those who are overweight or obese. But this way of thinking may be putting these patients at risk,” added Dr. Wijarnpreecha, who is a transplant hepatology fellow at the University of Michigan, Ann Arbor.

Key findings

Approximately 25% of U.S. adults live with NAFLD, an umbrella term for liver conditions in people who drink little to no alcohol. It is characterized by too much fat stored in the liver. Although most people have no symptoms, the condition can lead to other dangerous conditions, such as diabetes, cardiovascular disease, and cirrhosis of the liver, Dr. Wijarnpreecha said.

The investigators retrospectively studied a cohort of 18,793 adults diagnosed with NAFLD at the University of Michigan Hospital from 2012-2021. One aim was to compare the prevalence of cirrhosis, cardiovascular disease, metabolic diseases, and chronic kidney disease in relation to BMI.

They also classified people into four BMI categories: lean, overweight, obesity class 1, and obesity class 2-3.

Compared with non-lean patients, lean patients had a higher prevalence of peripheral arterial disease and stroke and a similar rate of cardiovascular disease based on identification of ICD codes.

Almost 6% of lean patients had peripheral arterial disease, compared with rates of approximately 4%-5% in overweight people and people with obesity. Similarly, more than 6% of the lean group experienced a stroke compared with 5% or less of the other BMI groups.

“We found that lean patients with NAFLD also had a significant higher prevalence of cardiovascular disease, independent of age, sex, race, smoking status, diabetes, hypertension, and dyslipidemia,” Dr. Wijarnpreecha said.

At the same time, compared with non-lean patients, lean patients had a lower prevalence of cirrhosis, diabetes mellitus, hypertension, dyslipidemia, and chronic kidney disease in an analysis that adjusted for confounders.
 

Exploring the unknown

Researchers now have a mystery on their hands: What is causing this unexpected higher risk of cardiovascular disease in lean people with NAFLD?

Loren Laine, MD, chief of the section of digestive diseases at Yale University School of Medicine, New Haven, Conn., and moderator of the media briefing, asked Wijarnpreecha for his leading theory behind this connection.

“We think that could be from a difference in lifestyle, diet, exercise, genetics, or even gut microbiota,” Dr. Wijarnpreecha replied. “But these are factors that we did not capture from this current study.”

“We are preparing to conduct additional research with longitudinal data to better understand NAFLD in lean patients,” Dr. Wijarnpreecha added.

“It’s an interesting finding, but there are some questions from this retrospective study,” said Arun J. Sanyal, MD, when asked to comment on the study.

Identifying and quantifying any alcohol use, smoking, or hypertension that could also have contributed to increased cardiovascular risk would be useful. Another question relates to how the population with NAFLD was identified. Was NAFLD an incidental finding in their diagnosis, asked Dr. Sanyal, director of the Stravitz-Sanyal Institute for Liver Disease & Metabolic Health at Virginia Commonwealth University, Richmond.

“I’m not dissing the study,” he said, “But like all the observations like this, I think we have to kick the tires.”

It’s an “important new observation” that requires further study to fully understand what it means and what the therapeutic implications might be. It is also important to assess any possible confounders and any causal relationship among these factors, Dr. Sanyal added.

“There’s no question it is important to continue to do these types of studies,” he added. “Through this kind of research we find new things that lead to the science that can then significantly change how we approach these issues.”

Non-alcoholic fatty liver disease (NAFLD) and metabolic associated fatty liver disease (MAFLD) demonstrate highly similar clinical courses and mortality rates, and a name change may not be clinically beneficial, based on data from more than 17,000 patients.

Instead, etiologic subcategorization of fatty liver disease (FLD) should be considered, reported lead author Zobair M. Younossi, MD, of Betty and Guy Beatty Center for Integrated Research, Inova Health System, Falls Church, Va., and colleagues.

“There is debate about whether NAFLD is an appropriate name as the term ‘non-alcoholic’ overemphasizes the absence of alcohol use and underemphasizes the importance of the metabolic risk factors which are the main drivers of disease progression,” the investigators wrote in Hepatology. “It has been suggested that MAFLD may better reflect these risk factors. However, such a recommendation is made despite a lack of a general consensus on the definition of ‘metabolic health’ and disagreements in endocrinology circles about the term ‘metabolic syndrome.’ Nevertheless, a few investigators have suggested that MAFLD but not NAFLD is associated with increased fibrosis and mortality.”

To look for clinical differences between the two disease entities, Dr. Younossi and colleagues turned to the National Health and Nutrition Examination Survey (NHANES). Specifically, the NHANES III and NHANES 2017-2018 cohorts were employed, including 12,878 and 4,328 participants, respectively.

MAFLD was defined as FLD with overweight/obesity, evidence of metabolic dysregulation, or type 2 diabetes mellitus. NAFLD was defined as FLD without excessive alcohol consumption or other causes of chronic liver disease. Patients were sorted into four groups: NAFLD, MAFLD, both disease types, or neither disease type. Since the categories were not mutually exclusive, the investigators compared clinical characteristics based on 95% confidence intervals. If no overlap was found, then differences were deemed statistically significant.

Diagnoses of NAFLD and MAFLD were highly concordant (kappa coefficient = 0.83-0.94). After a median of 22.8 years follow-up, no significant differences were found between groups for cause-specific mortality, all-cause mortality, or major clinical characteristics except those inherent to the disease definitions (for example, lack of alcohol use in NAFLD). Greatest risk factors for advanced fibrosis in both groups were obesity, high-risk fibrosis, and type 2 diabetes mellitus.

As anticipated, by definition, alcoholic liver disease and excess alcohol use were documented in approximately 15% of patients with MAFLD, but in no patients with NAFLD. As such, alcoholic liver disease predicted liver-specific mortality for MAFLD (hazard ratio, 4.50; 95% confidence interval, 1.89-10.75) but not NAFLD. Conversely, insulin resistance predicted liver-specific mortality in NAFLD (HR, 3.57; 95% CI, 1.35-9.42) but not MAFLD (HR, 0.84; 95% CI, 0.36-1.95).

“These data do not support the notion that a name change from NAFLD to MAFLD will better capture the risk for long-term outcomes of these patients or better define metabolically at-risk patients who present with FLD,” the investigators concluded. “On the other hand, enlarging the definition to FLD with subcategories of ‘alcoholic,’ ‘non-alcoholic,’ ‘drug-induced,’ etc. has merit and needs to be further considered. In this context, a true international consensus group of experts supported by liver and non-liver scientific societies must undertake an evidence-based and comprehensive approach to this issue and assess both the benefits and risks of changing the name.”

According to Rohit Loomba, MD, director of the NAFLD research center and professor of medicine in the division of gastroenterology and hepatology at University of California, San Diego, the study offers a preview of the consequences if NAFLD were changed to MAFLD, most notably by making alcohol a key driver of outcomes.

“If we change the name of a disease entity ... how does that impact natural history?” Dr. Loomba asked in an interview. “This paper gives you an idea. If you start calling it MAFLD, then people are dying from alcohol use, and they’re not dying from what we are currently seeing patients with NAFLD die of.”

He also noted that the name change could disrupt drug development and outcome measures since most drugs currently in development are directed at nonalcoholic steatohepatitis (NASH).

“Is it worth the headache?” Dr. Loomba asked. “How are we going to define NASH-related fibrosis? That probably will remain the same because the therapies that we will use to address that will remain consistent with what we are currently pursuing. ... It’s probably premature to change the nomenclature before assessing the impact on finding new treatment.”

Dr. Younossi disclosed relationships with BMS, Novartis, Gilead, and others. Dr. Loomba serves as a consultant to Aardvark Therapeutics, Altimmune, Anylam/Regeneron, Amgen, Arrowhead Pharmaceuticals, AstraZeneca, Bristol-Myer Squibb, CohBar, Eli Lilly, Galmed, Gilead, Glympse bio, Hightide, Inipharma, Intercept, Inventiva, Ionis, Janssen, Madrigal, Metacrine, NGM Biopharmaceuticals, Novartis, Novo Nordisk, Merck, Pfizer, Sagimet, Theratechnologies, 89 bio, Terns Pharmaceuticals, and Viking Therapeutics.

Non-alcoholic fatty liver disease (NAFLD) and metabolic associated fatty liver disease (MAFLD) demonstrate highly similar clinical courses and mortality rates, and a name change may not be clinically beneficial, based on data from more than 17,000 patients.

Instead, etiologic subcategorization of fatty liver disease (FLD) should be considered, reported lead author Zobair M. Younossi, MD, of Betty and Guy Beatty Center for Integrated Research, Inova Health System, Falls Church, Va., and colleagues.

“There is debate about whether NAFLD is an appropriate name as the term ‘non-alcoholic’ overemphasizes the absence of alcohol use and underemphasizes the importance of the metabolic risk factors which are the main drivers of disease progression,” the investigators wrote in Hepatology. “It has been suggested that MAFLD may better reflect these risk factors. However, such a recommendation is made despite a lack of a general consensus on the definition of ‘metabolic health’ and disagreements in endocrinology circles about the term ‘metabolic syndrome.’ Nevertheless, a few investigators have suggested that MAFLD but not NAFLD is associated with increased fibrosis and mortality.”

To look for clinical differences between the two disease entities, Dr. Younossi and colleagues turned to the National Health and Nutrition Examination Survey (NHANES). Specifically, the NHANES III and NHANES 2017-2018 cohorts were employed, including 12,878 and 4,328 participants, respectively.

MAFLD was defined as FLD with overweight/obesity, evidence of metabolic dysregulation, or type 2 diabetes mellitus. NAFLD was defined as FLD without excessive alcohol consumption or other causes of chronic liver disease. Patients were sorted into four groups: NAFLD, MAFLD, both disease types, or neither disease type. Since the categories were not mutually exclusive, the investigators compared clinical characteristics based on 95% confidence intervals. If no overlap was found, then differences were deemed statistically significant.

Diagnoses of NAFLD and MAFLD were highly concordant (kappa coefficient = 0.83-0.94). After a median of 22.8 years follow-up, no significant differences were found between groups for cause-specific mortality, all-cause mortality, or major clinical characteristics except those inherent to the disease definitions (for example, lack of alcohol use in NAFLD).

New clinical practice guidelines for the diagnosis and management of nonalcoholic fatty liver disease (NAFLD) are the first to be targeted specifically to primary care and endocrinology clinical settings.

They include 34 evidence-based clinical practice recommendations for screening, diagnosis, management, and referral, presented in a table and an algorithm flow chart as well as detailed text.

The new guidelines are by the American Association of Clinical Endocrinology and cosponsored by the American Association for the Study of Liver Diseases. They were presented at the annual scientific & clinical congress of the AACE and simultaneously published in Endocrine Practice.

These are “the first of this type for this field of medicine. The vast majority of patients with NAFLD are being seen in the primary care and endocrinology settings. Only when they get to the more advanced disease are they being referred to the liver specialists. So, we need to be the ones who are diagnosing and managing these patients because there just aren’t enough liver specialists to do that,” Scott Isaacs, MD, cochair of the writing panel for the guidelines, said in an interview.

80 million Americans have NAFLD, but very few are aware

The spectrum of NAFLD ranges from nonprogressive steatosis to the progressive conditions nonalcoholic steatohepatitis, fibrotic NASH, and end-stage NASH cirrhosis. And NASH, in turn, is a major cause of liver cancer. NAFLD is also strongly associated with insulin resistance, type 2 diabetes, atherogenesis, and myocardial dysfunction.

The global prevalence of NAFLD is about 25% and NASH, about 12%-14%. However, a recent study found that, among patients in endocrine and primary care clinics, more than 70% of patients with type 2 diabetes and more than 90% with type 2 diabetes who had a body mass index above 35 kg/m2 also had NAFLD, and more than 20% of those patients had significant liver fibrosis.

Problematically, very few people are aware they have either. “It’s so common. At least 80 million Americans have this but only about 6% know they have it. We talk about it a lot, but it’s not talked about enough,” said Dr. Isaacs, an endocrinologist who practices in Atlanta.

In fact, most cases of NAFLD are diagnosed incidentally when people undergo an ultrasound or a CT scan for another reason. And, in about 70% of cases the liver enzymes are normal, and those patients rarely undergo liver workups, Dr. Isaacs noted.

In an accompanying editorial, Suthat Liangpunsakul, MD, wrote: “In my perspective, as a hepatologist, this AACE guideline is very practical and easy to incorporate into routine practice in primary care and endocrinology settings. ... Early identification and risk stratification of patients with NAFLD, especially the degree of hepatic fibrosis, are required to reduce downstream health care costs and triage unwarranted specialty care referrals.”

And “an effective screening strategy may also identify those in primary care and endocrinology settings who may benefit from an appropriate referral to hepatologists before the development of portal hypertension complications, decompensated liver disease, and hepatocellular carcinoma,” added Dr. Liangpunsakul, professor of medicine in the division of gastroenterology and hepatology at Indiana University, Indianapolis.
 

Screening advised using new FIB-4 test

The guideline calls for screening all patients at high risk for NAFLD, including those with prediabetes, type 2 diabetes, obesity, and/or two or more cardiometabolic risk factors, or those with hepatic steatosis found on imaging, and/or persistently elevated plasma aminotransferase levels (that is, for more than 6 months).

The recommended screening test is the Fibrosis-4 (FIB-4) index, calculated using the patient’s age, AST level, platelet count, and ALT level: FIB-4 score = age (years) x AST (U/L)/PLT (10⁹/L) x ALT ½ (U/L).

Recently approved by the Food and Drug Administration, the FIB-4 has been demonstrated to help identify liver disease in primary care settings.

“We really want to encourage clinicians to do the screening. The first step is the FIB-4 test. It’s a mathematical calculation using blood tests that we do anyway,” Dr. Isaacs said in an interview.

The FIB-4 stratifies patients as being low, intermediate, or high risk for liver fibrosis. Those at low risk can be managed in primary care or endocrinology settings with a focus on obesity management and cardiovascular disease prevention. “Those at low risk on FIB-4 still have a high cardiovascular disease risk. They still need to be managed,” Dr. Isaacs observed.

For those at intermediate risk, a second noninvasive test – either a liver stiffness measurement by elastography or an enhanced liver fibrosis test – is advised. If the patient is found to be at high risk or is still indeterminant after two noninvasive tests, referral to a liver specialist for further testing, including possible biopsy, is advised.

Those found to be at high risk with the FIB-4 should also be referred to hepatology. In both the intermediate- and high-risk groups, management should be multidisciplinary, including a hepatologist, endocrinologist, and other professionals to prevent both cardiovascular disease and progression to cirrhosis, the guidelines say.

“The diagnosis isn’t about diagnosing liver fat. It’s about diagnosing fibrosis, or the risk for clinically significant fibrosis. That’s really where the challenge lies,” Dr. Isaacs commented.
 

NAFLD treatment in endocrinology and primary care: CVD prevention

During the presentation at the AACE meeting, guideline panel cochair Kenneth Cusi, MD, chief of endocrinology, diabetes, and metabolism at the University of Florida, Gainesville, summarized current and future treatments for NAFLD.

Lifestyle intervention, cardiovascular risk reduction, and weight loss for those who are overweight or obese are recommended for all patients with NAFLD, including structured weight-loss programs, antiobesity medications, and bariatric surgery if indicated.

There are currently no FDA-approved medications specifically for NASH, but pioglitazone, approved for type 2 diabetes, and glucagonlike peptide–1 agonists, approved for type 2 diabetes and weight loss, have been shown to be effective in treating the condition and preventing progression. Other treatments are in development, Dr. Cusi said.  

The guideline also includes a section on diagnosis and management of NAFLD in children and adolescents. Here, the FIB-4 is not recommended because it isn’t accurate due to the age part of the equation, so liver enzyme tests are used in pediatric patients considered at high risk because of clinical factors. Management is similar to adults, except not all medications used in adults are approved for use in children.

In the editorial, Dr. Liangpunsakul cautioned that “the level of uptake and usage of the guideline may be an obstacle.”

To remedy that, he advised that “the next effort should gear toward distributing this guideline to the targeted providers and developing the ‘feedback platforms’ on its execution in the real-world. ... The successful implementation of this AACE guideline by the primary care providers and endocrinologists, hopefully, will deescalate the future burden of NAFLD-related morbidity and mortality.”

Dr. Isaacs and Dr. Liangpunsakul have reported no relevant financial relationships. Dr. Cusi has reported receiving research support towards the University of Florida as principal investigator from the National Institute of Health, Echosens, Inventiva, Nordic Bioscience, Novo Nordisk, Poxel, Labcorp, and Zydus, and is a consultant for Altimmune, Akero, Arrowhead, AstraZeneca, 89Bio, Bristol-Myers Squibb, Coherus, Intercept, Lilly, Madrigal, Merck, Novo Nordisk, Quest, Sagimet, Sonic Incytes, Terns, and Thera Technologies.

In the editorial, Dr. Liangpunsakul cautioned that “the level of uptake and usage of the guideline may be an obstacle.”

To remedy that, he advised that “the next effort should gear toward distributing this guideline to the targeted providers and developing the ‘feedback platforms’ on its execution in the real-world. ... The successful implementation of this AACE guideline by the primary care providers and endocrinologists, hopefully, will deescalate the future burden of NAFLD-related morbidity and mortality.”

Dr. Isaacs and Dr. Liangpunsakul have reported no relevant financial relationships. Dr. Cusi has reported receiving research support towards the University of Florida as principal investigator from the National Institute of Health, Echosens, Inventiva, Nordic Bioscience, Novo Nordisk, Poxel, Labcorp, and Zydus, and is a consultant for Altimmune, Akero, Arrowhead, AstraZeneca, 89Bio, Bristol-Myers Squibb, Coherus, Intercept, Lilly, Madrigal, Merck, Novo Nordisk, Quest, Sagimet, Sonic Incytes, Terns, and Thera Technologies.

Espresso consumption is associated with higher total cholesterol levels, a population-based, cross-sectional study suggests.

Elevations in serum total cholesterol level were significantly linked to espresso consumption, particularly in men, Åsne Lirhus Svatun, of the Arctic University of Norway, Tromsø, and colleagues reported.

Drinking boiled/plunger coffee was associated with significantly higher serum total cholesterol levels in women and men. There was a significant relationship between filtered coffee consumption and total cholesterol, but only among women, the researchers reported.

“Doctors could become mindful of asking about coffee consumption when taking up the history of patients with elevated serum cholesterol,” study author Maja-Lisa Løchen, MD, PhD, of the Arctic University of Norway, said in an interview.

“Guiding patients to change from plunger coffee or other unfiltered coffee types to filtered or instant coffee could be a part of a lifestyle intervention to lower serum cholesterol levels.”

The results were published online in the journal Open Heart.

Previous studies of the relationship between serum cholesterol and espresso have had varying outcomes, the researchers noted.

Given that coffee consumption is high worldwide, even slight health effects can have substantial health consequences, the researchers noted. “Coffee was included for the first time in the 2021 ESC [European Society of Cardiology] guidelines on cardiovascular disease prevention in clinical practice. Increased knowledge on espresso coffee’s association with serum cholesterol will improve the recommendations regarding coffee consumption.”

“I don’t think that the findings in this paper are necessarily enough to change any advice about coffee,” said David Kao, MD, an associate professor medicine at the University of Colorado at Denver, Aurora, in commenting on the findings. “This is partly because the most important thing at the end of the day is whether subsequent events like heart attack or stroke increased or decreased. This analysis was not designed to answer that question.”

“If one has to choose between this study, which would suggest to drink less coffee to maintain low cholesterol, and the others, which would suggest increasing coffee consumption might reduce risk of multiple kinds of CVD, one should choose the latter,” Dr. Kao concluded.

In the current study, the investigators assessed 21,083 participants in the Tromsø Study in Northern Norway. The mean age of the participants was 56.4 years. Using multivariable linear regression, the researchers compared the relationship between each level of coffee consumption with no coffee consumption as the reference point and serum total cholesterol as the dependent variable. They tested for sex differences and adjusted for relevant covariates.

The findings indicate that drinking three to five cups of espresso each day was significantly linked with greater serum total cholesterol by 0.16 mmol/L (95% confidence interval, 0.07-0.24) for men and by 0.09 mmol/L (95% CI, 0.01-0.17) for women in comparison with participants who did not drink espresso daily.

Compared with individuals who did not drink plunger/boiled coffee, consumption of six or more cups of plunger/boiled coffee each day was linked with elevated serum total cholesterol levels by 0.23 mmol/L (95% CI, 0.08-0.38) for men and 0.30 mmol/L (95% CI, 0.13-0.48) for women.

Notably, for women but not men, there was an increase in serum total cholesterol of 0.11 mmol/L (95% CI, 0.03-0.19) in association with drinking six or more cups of filtered coffee per day.

When excluding participants who did not drink instant coffee, drinking instant coffee yielded a significant linear pattern for both men and women, but there was not a dose-dependent association.

These data show that sex differences were significant for every coffee type except plunger/boiled coffee, the authors noted.

Limitations of the study include its cross-sectional design; lack of generalizability of the data, given that the cohort primarily consisted of elderly adults and middle-aged White persons; and the fact that the study did not adjust for all confounding variables, the researchers noted.

Also among the study’s limitations were that some data were self-reported, and the missing indicator approach was implemented to assess data, the authors added.

Future research efforts should focus on following this cohort over many years to determine how consumption of various types of coffee is linked with events such as heart failure, stroke, and myocardial infarction. This insight would be important in offering guidance on whether the style of coffee preparation matters, concluded Dr. Kao.

The study was supported by a number of sources, including the Arctic University of Norway and the Northern Norway Regional Health Authority. The study investigators reported no conflicts of interest.

Use of race-based diabetes screening thresholds could reduce the disparity that arises from current screening guidelines in the United States, new research suggests.

In August 2021, the U.S. Preventive Services Task Force (USPSTF) lowered the recommended age for type 2 diabetes screening from 40 to 35 years among people with a body mass index of 25 kg/m² or greater.

However, the diabetes rate among ethnic minorities aged 35-70 years in the United States is not just higher overall but, in certain populations, also occurs more frequently at a younger age and at lower BMIs, the new study indicates.

Among people with a BMI below 25 kg/m², the diabetes prevalence is two to four times higher among Asian, Black, and Hispanic Americans than among the U.S. White population.

And the authors of the new study, led by Rahul Aggarwal, MD, predict that if screening begins at age 35 years, the BMI cut-off equivalent to 25 kg/m² for White Americans would be 18.5 kg/m2 for Hispanic and Black Americans and 20 kg/m² for Asian Americans.

“While diabetes has often been thought of as a disease that primarily affects adults with overweight or [obesity], our findings suggest that normal-weight adults in minority groups have surprisingly high rates of diabetes,” Dr. Aggarwal, senior resident physician in internal medicine at Harvard Medical School, Boston, told this news organization.

“Assessing diabetes risks in certain racial/ethnic groups will be necessary, even if these adults do not have overweight or [obesity],” he added.

Not screening in this way “is a missed opportunity for early intervention,” he noted.  

And both the authors and an editorialist stress that the issue isn’t just theoretical.

“USPSTF recommendations influence what payers choose to cover, which in turn determines access to preventative services ... Addressing the staggering inequities in diabetes outcomes will require substantial investments in diabetes prevention and treatment, but making screening more equitable is a good place to start,” said senior author Dhruv S. Kazi, MD, of the Smith Center for Outcomes Research in Cardiology and director of the Cardiac Critical Care Unit at Beth Israel, Boston.
 

Screen minorities at a younger age if current BMI threshold kept

In their study, based on data from the National Health and Nutrition Examination Survey (NHANES) for 2011-2018, Dr. Aggarwal and colleagues also calculated that, if the BMI threshold is kept at 25 kg/m², then the equivalent age cut-offs for Asian, Black, and Hispanic Americans would be 23, 21, and 25 years, respectively, compared with 35 years for White Americans.

The findings were published online  in the Annals of Internal Medicine.

The prevalence of diabetes in those aged 35-70 years in the NHANES population was 17.3% for Asian Americans and 12.5% for those who were White (odds ratio, 1.51 vs. Whites). Among Black Americans and Mexican Americans, the prevalence was 20.7% and 20.6%, respectively, almost twice the prevalence in Whites (OR, 1.85 and 1.80). For other Hispanic Americans, the prevalence was 16.4% (OR, 1.37 vs. Whites). All of those differences were significant, compared with White Americans.

Undiagnosed diabetes was also significantly more common among minority populations, at 27.6%, 22.8%, 21.2%, and 23.5% for Asian, Black, Mexican, and other Hispanic Americans, respectively, versus 12.5% for White Americans.
 

‘The time has come for USPSTF to offer more concrete guidance’

“While there is more work to be done on carefully examining the long-term risk–benefit trade-off of various diabetes screening, I believe the time has come for USPSTF to offer more concrete guidance on the use of lower thresholds for screening higher-risk individuals,” Dr. Kazi told this news organization.

The author of an accompanying editorial agrees, noting that in a recent commentary the USPSTF, itself, “acknowledged the persistent inequalities across the screening-to-treatment continuum that result in racial/ethnic health disparities in the United States.”

And the USPSTF “emphasized the need to improve systems of care to ensure equitable and consistent delivery of high-quality preventive and treatment services, with special attention to racial/ethnic groups who may experience worse health outcomes,” continues Quyen Ngo-Metzger, MD, Kaiser Permanente Bernard J. Tyson School of Medicine, Pasadena, California.

For other conditions, including cancer, cardiovascular disease, and infectious disease, the USPSTF already recommends risk-based preventive services.

“To address the current inequity in diabetes screening, the USPSTF should apply the same consideration to its diabetes screening recommendation,” she notes.
 

‘Implementation will require an eye for pragmatism’

Asked about how this recommendation might be carried out in the real world, Dr. Aggarwal said in an interview that, because all three minority groups with normal weight had similar diabetes risk profiles to White adults with overweight, “one way for clinicians to easily implement these findings is by screening all Asian, Black, and Hispanic adults ages 35-70 years with normal weight for diabetes, similarly to how all White adults ages 35-70 years with overweight are currently recommended for screening.”

Dr. Kazi said: “I believe that implementation will require an eye for pragmatism,” noting that another option would be to have screening algorithms embedded in the electronic health record to flag individuals who qualify.

In any case, “the simplicity of the current one-size-fits-all approach is alluring, but it is profoundly inequitable. The more I look at the empiric evidence on diabetes burden in our communities, the more the status quo becomes untenable.”

However, Dr. Kazi also noted, “the benefit of any screening program relates to what we do with the information. The key is to ensure that folks identified as having diabetes – or better still prediabetes – receive timely lifestyle and pharmacological interventions to avert its long-term complications.”

This study was supported by institutional funds from the Richard A. and Susan F. Smith Center for Outcomes Research in Cardiology. Dr. Aggarwal, Dr. Kazi, and Dr. Ngo-Metzger have reported no relevant relationships.
