Experts discuss how to best protect people with diabetes from serious COVID-19 outcomes in a newly published article that summarizes in-depth discussions on the topic from a conference held online last year.

Lead author and Diabetes Technology Society founder and director David C. Klonoff, MD, said in an interview: “To my knowledge this is the largest article or learning that has been written anywhere ever about the co-occurrence of COVID-19 and diabetes and how COVID-19 affects diabetes ... There are a lot of different dimensions.” 

The 37-page report covers all sessions from the Virtual International COVID-19 and Diabetes Summit, held Aug. 26-27, 2020, which had 800 attendees from six continents, on topics including pathophysiology and COVID-19 risk factors, the impact of social determinants of health on diabetes and COVID-19, and psychological aspects of the COVID-19 pandemic for people with diabetes.

The freely available report was published online Jan. 21 in the Journal of Diabetes Science and Technology by Jennifer Y. Zhang of the Diabetes Technology Society, Burlingame, Calif., and colleagues.

Other topics include medications and vaccines, outpatient diabetes management during the COVID-19 pandemic and the growth of telehealth, inpatient management of diabetes in patients with or without COVID-19, ethical considerations, children, pregnancy, economics of care for COVID-19, government policy, regulation of tests and treatments, patient surveillance/privacy, and research gaps and opportunities.

“A comprehensive report like this is so important because it covers such a wide range of topics that are all relevant when it comes to protecting patients with diabetes during a pandemic. Our report aims to bring together all these different aspects of policy during the pandemic, patient physiology, and patient psychology, so I hope it will be widely read and widely appreciated,” Ms. Zhang said in an interview.

Two important clinical trends arising as a result of the pandemic – the advent of telehealth in diabetes management and the use of continuous glucose monitoring (CGM) in hospital – are expected to continue even after COVID-19 abates, said Dr. Klonoff, medical director of the Diabetes Research Institute at Mills-Peninsula Medical Center, San Mateo, Calif.


 

Telehealth in diabetes here to stay, in U.S. at least  

Dr. Klonoff noted that with diabetes telehealth, or “telediabetes” as it’s been dubbed, by using downloaded device data patients don’t have to travel, pay for parking, or take as much time off work. “There are advantages ... patients really like it,” he said.

And for health care providers, an advantage of remote visits is that the clinician can look at the patient while reviewing the patient’s data. “With telehealth for diabetes, the patient’s face and the software data are right next to each other on the same screen. Even as I’m typing I’m looking at the patient ... I consider that a huge advantage,” Dr. Klonoff said.

Rule changes early in the pandemic made the shift to telehealth in the United States possible, he said.

“Fortunately, Medicare and other payers are covering telehealth. It used to be there was no coverage, so that was a damper. Now that it’s covered I don’t think that’s going to go back. Everybody likes it,” he said. 
 

CGM in hospitals helps detect hypoglycemia on wards

Regarding the increase of inpatient CGM (continuous glucose monitoring) prompted by the need to minimize patient exposure of nursing staff during the pandemic and the relaxing of Food and Drug Administration rules about its use, Dr. Klonoff said this phenomenon has led to two other positive developments.

“For FDA, it’s actually an opportunity to see some data collected. To do a clinical trial [prior to] March 2020 you had to go through a lot of processes to do a study. Once it becomes part of clinical care, then you can collect a lot of data,” he noted.   

Moreover, Dr. Klonoff said there’s an important new area where hospital use of CGM is emerging: detection of hypoglycemia on wards.

“When a patient is in the ICU, if they become hypoglycemic or hyperglycemic it will likely be detected. But on the wards, they simply don’t get the same attention. Just about every doctor has had a case where somebody drifted into hypoglycemia that wasn’t recognized and maybe even died,” he explained.

If, however, “patients treated with insulin could all have CGMs that would be so useful. It would send out an alarm. A lot of times people don’t eat when you think they will. Suddenly the insulin dose is inappropriate and the nurse didn’t realize. Or, if IV nutrition stops and the insulin is given [it can be harmful].”

Another example, he said, is a common scenario when insulin is used in patients who are treated with steroids. “They need insulin, but then the steroid is decreased and the insulin dose isn’t decreased fast enough. All those situations can be helped with CGM.”

Overall, he concluded, COVID-19 has provided many lessons, which are “expanding our horizons.”

Ms. Zhang has reported no relevant financial relationships. Dr. Klonoff has reported being a consultant for Dexcom, EOFlow, Fractyl, Lifecare, Novo Nordisk, Roche Diagnostics, Samsung, and Thirdwayv.

Marius Pharmaceuticals has submitted a new drug application (NDA) to the Food and Drug Administration for Kyzatrex, an oral testosterone replacement therapy (TRT).

With this NDA, the company is seeking approval for Kyzatrex as a treatment for adult men with primary and secondary hypogonadism, also known as testosterone deficiency. Marius has requested a priority review that, if accepted, would result in an anticipated 6-month review period.

Current treatment options for hypogonadal men consist of therapies with safety concerns, such as cardiovascular and metabolic risks, that make patient adherence to treatment very low.

Kyzatrex is a novel oral formulation of testosterone undecanoate administered twice daily in a soft gelatin capsule.

“TRT remains a therapeutic challenge because there are worrisome and conflicting data related to increased cardiovascular disease risk, which has special relevance to high-risk diabetic populations,” Paul S. Jellinger, MD, professor of clinical medicine at the University of Miami, told this news organization. Furthermore, “injectable depot testosterone may be associated with peak supraphysiological levels and a substantial increase in hemoglobin. Topical testosterone offers more stable levels without a peak and trough, but in some men achieving physiologic levels may be difficult.”

The NDA is supported by results from a 6-month treatment extension of the pivotal phase 3 MRS-TU-2019 study (NCT04467697). Final results from this study have not been presented, but the company wrote in a press release that the results will be published some time in 2021.

They further reported that Kyzatrex was well tolerated by patients, with more than 96% of study participants completing 90 days of treatment in the pivotal phase 3 study. Study patients achieved average testosterone levels in the normal range.

Across the pooled phase 3 trials, the most frequent treatment-related treatment-emergent adverse event (TEAE) was hypertension, and no serious TEAEs were considered treatment related.

“We are extremely proud to have generated compelling efficacy and safety data in our phase 3 trials,” said Om Dhingra, PhD, cofounder and CEO of Marius. “We look forward to continuing to work collaboratively with the FDA on the review of our application, and if approved, Kyzatrex has the potential to become the standard of care for the treatment of primary and secondary hypogonadism globally.”

“An oral [testosterone] preparation with steady state physiologic levels would be a welcome addition to our choices for therapy assuming, of course, the absence of adverse effects,” explained Dr. Jellinger. “However, the greater challenge of testosterone therapy is the appropriate selection of those suited for testosterone replacement therapy.”

The company also plans to submit a marketing authorization application with the European Medicines Agency in the first half of 2022.

Use of sodium-glucose cotransporter 2 (SGLT2) inhibitors during acute COVID-19 illness raises the risk for euglycemic diabetic ketoacidosis (euDKA), a new case series suggests.

Five patients with type 2 diabetes who were taking SGLT2 inhibitors presented in DKA despite having glucose levels below 300 mg/dL. The report was published online last month in AACE Clinical Case Reports by Rebecca J. Vitale, MD, and colleagues at Brigham and Women’s Hospital, Boston.

“A cluster of euglycemic DKA cases at our hospital during the first wave of the pandemic suggests that patients with diabetes taking SGLT2 inhibitors may be at enhanced risk for euDKA when they contract COVID-19,” senior author Naomi D.L. Fisher, MD, said in an interview.

Dr. Fisher, an endocrinologist, added: “This complication is preventable with the simple measure of holding the drug. We are hopeful that widespread patient and physician education will prevent future cases of euDKA as COVID-19 infections continue to surge.”

These cases underscore recommendations published early in the COVID-19 pandemic by an international panel, she noted.

“Patients who are acutely ill with nausea, vomiting, abdominal pain, or diarrhea, or who are experiencing loss of appetite with reduced food and fluid intake, should be advised to hold their SGLT2 inhibitor. This medication should not be resumed until patients are feeling better and eating and drinking normally.”  

On the other hand, “If patients with asymptomatic or mild COVID-19 infection are otherwise well, and are eating and drinking normally, there is no evidence that SGLT2 inhibitors need to be stopped. These patients should monitor [themselves] closely for worsening symptoms, especially resulting in poor hydration and nutrition, which would be reason to discontinue their medication.” 
 

Pay special attention to the elderly, those with complications

However, special consideration should be given to elderly patients and those with medical conditions known to increase the likelihood of severe infection, like heart failure and chronic obstructive pulmonary disease, Dr. Fisher added.

The SGLT2 inhibitor class of drugs causes significant urinary glucose excretion, and they are also diuretics. A decrease in available glucose and volume depletion are probably both important contributors to euDKA, she explained.

With COVID-19 infection the euDKA risk is compounded by several mechanisms. Most cases of euDKA are associated with an underlying state of starvation that can be triggered by vomiting, diarrhea, loss of appetite, and poor oral intake.

In addition – although not yet known for certain – SARS-CoV-2 may also be toxic to pancreatic beta cells and thus reduce insulin secretion. The maladaptive inflammatory response seen with COVID-19 may also contribute, she said.  

The patients in the current case series were three men and two women seen between March and May 2020. They ranged in age from 52 to 79 years.

None had a prior history of DKA or any known diabetes complications. In all of them, antihyperglycemic medications, including SGLT2 inhibitors, were stopped on hospital admission. The patients were initially treated with intravenous insulin, and then subcutaneous insulin after the DKA diagnosis.

Three of the patients were discharged to rehabilitation facilities on hospital days 28-47 and one (age 53 years) was discharged home on day 11. The other patient also had hypertension and nonalcoholic steatohepatitis.

Childhood treatment with recombinant human growth hormone was associated with a significantly increased risk of cardiovascular events, based on data from more than 3,000 individuals.

“Both excess levels of growth hormone and [growth hormone deficiency] have been associated with increased cardiovascular morbidity and mortality,” but data on long-term cardiovascular morbidity in individuals treated with growth hormone in childhood are lacking, wrote Anders Tinblad, MD, of Karolinska Institutet, Stockholm, and colleagues.

In a population-based cohort study published in JAMA Pediatrics, the researchers identified 3,408 Swedish patients treated as children with recombinant human growth hormone (rhGH) between Jan. 1, 1985, and Dec. 31, 2010, and compared each with 15 matched controls (a total of 50,036 controls). The patients were treated for one of three conditions: isolated growth hormone deficiency (GHD), small for gestational age (SGA), and idiopathic short stature (ISS).

Data on cardiovascular outcomes were collected from health care and population-based registers and analyzed between Jan. 1, 1985, and Dec. 31, 2014. The average age of the participants at the study’s end was 25.1 years.

In all, 1,809 cardiovascular disease events were recorded over a median follow-up period of 14.9 years, for an incidence rate of 25.6 events per 10,000 person-years in patients and 22.6 events per 10,000 person-years in controls.

When separated by sex, the incidence was higher in female patients compared with controls (31.2 vs. 23.4 events per 10,000 person-years, respectively, but similar in male patients vs. controls (23.3 vs. 22.3 events per 10,000 person-years). “Differences in estrogen levels or responsiveness to rhGH treatment have previously been hypothesized as possible explanations, but the underlying mechanism for this sex difference still remains unclear and merits further investigation,” the researchers wrote.

Overall, the highest adjusted hazard ratios occurred in subgroups of patients with the longest treatment duration (HR 2.08) and highest cumulative dose of growth hormone (HR 2.05), but no association was noted between highest daily hormone dose and cardiovascular event risk. Hazard ratios were higher across all three treatment subgroups of SGA, GHD, and ISS compared with controls (HR 1.97, 1.66, and 1.55, respectively).

“The association between childhood rhGH treatment and CVD events was also seen when assessing only severe CVD outcomes, but with even lower absolute risks,” the researchers noted.

The study findings were limited by several factors including the potential for confounding by treatment indication and the lack of long-term follow-up data given the relatively young age of the study population, the researchers said. The results were strengthened by the large sample size and showed that the absolute risk for overall and severe cardiovascular disease in children treated with growth hormones was low, “which could be reassuring to individual patients,” they added. However, “At the group level, and perhaps especially for female patients and those treated for SGA indication, further close monitoring and future studies of CVD safety are warranted,” they concluded.
 

Safety and ethical concerns persist

Although the study authors cite limited conclusions on causality and low absolute risk, several issues persist that prompt ongoing analysis of pediatric growth hormone use, namely “worrisome indirect evidence, challenges and limitations in the direct evidence, and the changing world of growth hormone treatment,” Adda Grimberg, MD, of the University of Pennsylvania, Philadelphia, wrote in an accompanying editorial.

“Although evidence asserts that neither growth hormone nor insulinlike growth factor I is carcinogenic, the basic science and oncology literatures are rife with reports showing that they can make aberrant cells more aggressive,” and such indirect evidence supports the need for more direct evidence of possible harm from growth hormone treatment, Dr. Grimberg wrote. Most current safety data on growth hormone come from postmarketing surveillance studies, but these studies do not include controls or data on outcomes after discontinuation of treatment, she noted.

The current study, while able to follow patients across the lifespan, cannot indicate “whether the small but increased risk of cardiovascular disease found in this study was caused by the pediatric growth hormone treatment that identified the participants, by the conditions being treated, by other potential confounder(s) not captured by the study’s methods, or by a combination of the above,” said Dr. Grimberg.

In addition, “the move from replacement of GHD to pharmacologic height augmentation in children who already make sufficient growth hormone had the potential to change the safety profile of treatment,” she said.

“Parents of patients in pediatric primary care practices and of patients seeking growth-related care in a subspecialty endocrine clinic rated treatment characteristics (i.e., proven efficacy and safety) as the factor most having a big or extreme effect on their growth-related medical decision-making,” Dr. Grimberg said. “The centrality of treatment safety to patient-family decision-making underscores the importance of continued scrutiny of growth hormone safety as the treatment and its recipients continue to evolve,” she concluded.

The study was supported by the Swedish Research Council, the Stockholm City Council, the Karolinska Institute, the Society for Child Care, Sahlgrenska University Hospital, and the Stockholm County Council’s combined clinical residency and PhD training program. Lead author Dr. Tidblad disclosed funding from the Society for Child Care and Stockholm County Council during the conduct of the study and personal fees from Pfizer. Dr. Grimberg disclosed serving as a member of the steering committee for the Pfizer International Growth Study Database, and as a consultant for the Pediatric Endocrine Society GH Deficiency Knowledge Center, sponsored by Sandoz AG.

Childhood treatment with recombinant human growth hormone was associated with a significantly increased risk of cardiovascular events, based on data from more than 3,000 individuals.

“Both excess levels of growth hormone and [growth hormone deficiency] have been associated with increased cardiovascular morbidity and mortality,” but data on long-term cardiovascular morbidity in individuals treated with growth hormone in childhood are lacking, wrote Anders Tinblad, MD, of Karolinska Institutet, Stockholm, and colleagues.

In a population-based cohort study published in JAMA Pediatrics, the researchers identified 3,408 Swedish patients treated as children with recombinant human growth hormone (rhGH) between Jan. 1, 1985, and Dec. 31, 2010, and compared each with 15 matched controls (a total of 50,036 controls). The patients were treated for one of three conditions: isolated growth hormone deficiency (GHD), small for gestational age (SGA), and idiopathic short stature (ISS).

A scoring system that predicts risk for new heart failure over 5 years that is based solely on a few familiar, readily available biomarkers could potentially help steer patients with diabetes or even prediabetes toward HF-preventive therapies, researchers proposed based on a new study.

They foresee the risk-stratification tool, based on data pooled from three major community-based cohort studies but not independently validated, as a way to select patients with diabetes and prediabetes for treatment with SGLT2 inhibitors.

Several members of that drug class, conceived as antidiabetic agents, have been shown to help in prevention or treatment of HF in patients with diabetes and those without diabetes but at increased cardiovascular (CV) risk. Yet their uptake in practice has been lagging, the group noted.

Most HF benefits in the SGLT2 inhibitor trials “were seen in patients who have established cardiovascular disease – basically a history of heart attack or stroke,” Ambarish Pandey, MD, MSCS, University of Texas Southwestern Medical Center, Dallas, said in an interview.

“So we wanted to see how we can identify high-risk patients without a history of cardiovascular disease using these biomarkers, as an approach to targeting SGLT2 inhibitors, which are fairly expensive therapies,” he said. Without such risk stratification, “you end up treating so many more patients to get very modest returns.”

The group developed a scoring system based on four biomarkers that are “easily measured with inexpensive tests,” Dr. Pandey said: high-sensitivity-assay cardiac troponin T (hs-cTnT) and C-reactive protein (hs-CRP) levels, N-terminal of the prohormone brain natriuretic peptide (NT-proBNP) levels, and electrocardiography for evidence of left-ventricular hypertrophy (ECG-LVH).

The derivation cohort consisted of participants in the Atherosclerosis Risk in Communities RIC, Dallas Heart Study, and Multi-Ethnic Study of Atherosclerosis Multi-Ethnic Study of Atherosclerosis epidemiologic studies who were free of coronary heart disease, stroke, or HF for whom there were sufficient data on CV risk factors and the four biomarkers. None were taking SGLT2 inhibitors at enrollment in their respective studies, the researchers noted.

Members of the pooled cohorts who had diabetes or prediabetes were assigned 1 point for each abnormal biomarker. The 5-year risk for incident HF went up continuously along with the score in people with diabetes and in those with prediabetes, the latter defined as a fasting plasma glucose level from 100 mg/dL to less than 126 mg/dL.

For those with a score of 1, compared with 0, for example, the risk for HF went up 82% with diabetes and 40% with prediabetes. But for those with a score of 3 or 4, the risk went up more than four and a half times with diabetes and more than three and a half times for those with prediabetes. Risk increases were independent of other likely HF risk factors and consistently significant.

The analysis was published Jan. 6 in JACC: Heart Failure.

The biomarker score should be especially useful in patients considered at low to intermediate risk, based on clinical characteristics, as a means to identify residual HF risk and, potentially, select candidates for SGLT2-inhibitor therapy, Dr. Pandey said.

“The other purpose of the study was to broaden the scope of heart failure prevention in dysglycemia by looking also at prediabetes, not just diabetes,” he said. There isn’t much high-quality evidence supporting SGLT2-inhibitor therapy in prediabetes, but it follows that the drugs may be helpful in prediabetes because they are protective in patients with and without diabetes.

“Our work suggests that prediabetes patients who have elevated biomarkers are at a higher risk of heart failure,” Dr. Pandey said, suggesting that the HF risk score could potentially help select their drug therapy as well.

The current study seems “to provide a proof of concept that one can use circulating biomarkers to more precisely identify patients in whom therapies might be expected to exert greatest benefit,” which is especially important for potentially expensive agents like the SGLT2 inhibitors, James L. Januzzi, MD, Massachusetts General Hospital, Boston, said in an interview.

Importantly in the analysis, a greater number of biomarker abnormalities not only corresponded to rising levels of risk, the risk increases were “dramatic,” and therefore so was the supposed potential benefit of SGLT2-inhibitor therapy, said Dr. Januzzi, who isn’t a coauthor but was an editor for its publication in JACC: Heart Failure.

The uptake of SGLT2 inhibitors for heart failure in practice has been less rapid than hoped, he observed, so if “this hypothetical construct holds up” for the drug class, “it might actually help kick-start focusing on who might optimally receive the drugs.”

Elevated levels of hs-cTnT, hs-CRP, and NT-proBNP, as well as presence of ECG-LVH, were each independently associated with a significantly increased 5-year risk for HF in unadjusted and adjusted analyses of the 6,799 people in the pooled cohort, 33.2% of whom had diabetes and 66.8% of whom had prediabetes, the group writes.

The scoring system would require validation in other cohorts before it could be used, Dr. Pandey observed; once there is “robust validation,” it might be applied first to patients with dysglycemia at intermediate CV risk by standard clinical measures.

Certainly the HF risk-stratification scoring system requires validation in other studies, Dr. Januzzi agreed. But it is intuitively appealing, and the study’s results are consistent with “data that we’re submitting for publication imminently” based on the CANVAS CV-outcomes trial of the SGLT2 inhibitor canagliflozin (Invokana) in patients with diabetes.

Dr. Pandey disclosed receiving support from the Gilead Sciences Research Scholar Program and serving on an advisory board of Roche Diagnostics. Dr. Januzzi disclosed receiving grant support from Novartis, Applied Therapeutics, and Innolife; consulting for Abbott Diagnostics, Janssen, Novartis, Quidel, and Roche Diagnostics; and serving on end-point committees or data safety monitoring boards for trials supported by Abbott, AbbVie, Amgen, CVRx, Janssen, MyoKardia, and Takeda.

People who have brown fat detected on imaging seem to be at reduced risk of cardiac and metabolic conditions, ranging from type 2 diabetes to hypertension and coronary artery disease, with a notably strong effect in people with obesity, according to a new study of more than 52,000 individuals who had PET/CT scans as part of cancer evaluation.

Although this has been studied for decades in newborns and animals, only in the past decade have scientists appreciated that some adults have brown fat, typically around the neck and shoulders.

The new study, by far the largest of its kind in humans, appears to confirm the health benefits of brown fat suggested by previous studies, Tobias Becher, MD, and colleagues from The Rockefeller University, New York, wrote in their article published online Jan. 4 in Nature Medicine.

“Our study indicates an important contribution of brown adipose tissue to cardiometabolic health and suggests ... [it] has therapeutic potential in humans,” they stated.

But Caroline M. Apovian, MD, Center for Weight Management and Wellness, Brigham and Women’s Hospital, Boston, is more cautious in her interpretation of the findings.

“It’s nice to see that what we believe about this is correct, and it’s great to see that with obesity and more brown fat there is reduced diabetes and hypertension, but it’s only an association,” she said in an interview.

“This is a good study, but I don’t think we have an understanding of exactly why some people have more brown fat than others, how white fat becomes brown fat, the role of therapeutics, or if it’s important to try to create more brown fat.

“We don’t know if it’s a matter of exercise or something like living in a colder environment, so we need to find out whether or not brown fat is, for instance, a genetic issue, and if it is, if there is a way to increase it in humans,” she added.

And the fact that the study included patients with or being screened for cancer is one of the most important limitations of the study, Dr. Apovian noted.
 

Brown fat detected in 10% of participants

Contrary to white fat, which stores energy, brown fat is thermogenic, activated by cold conditions, and instead burns energy. And although animal studies have shown a link between brown fat and improvements in glucose and lipid homeostasis, the effects of brown fat in humans are not well understood.

Dr. Becher and colleagues explained that large-scale studies of brown fat have been practically impossible because the tissue only shows up on medical imaging and it would be unethical to expose people to radiation just to study brown fat.  

But they realized that, across the street from their lab, many thousands of people visit Memorial Sloan Kettering Cancer Center each year to undergo PET/CT scans for cancer evaluation.

Because radiologists routinely take note when brown adipose tissue is detected to prevent its misinterpretation as a tumor, the information was readily available with the scan data.

“We realized this could be a valuable resource to get us started with looking at brown fat at a population scale,” Dr. Becher said in a press statement from The Rockefeller University.

So they reviewed 134,529 PET/CT scans from 52,487 individuals attending Memorial Sloan Kettering between June 2009 and March 2018 for indications ranging from cancer diagnosis to treatment or surveillance.

Participants were classified by the presence or absence of brown adipose tissue and researchers were able to use electronic health records to comprehensively examine associations between brown fat and rates of disease.

Overall, brown adipose tissue was identified in 5,070 (9.7%) of patients, with higher rates of brown fat among women than men (13.8% vs. 4.9%; P < .0001) and reduced rates with advancing age (P < .0001), as has been observed in previous studies.

The researchers noted, however, that this rate of around 10% of people having brown fat is likely an underestimate because the patients had been instructed to avoid cold exposure, exercise, and caffeine – all of which are thought to increase brown adipose tissue – prior to having their scans.
 

Does brown fat mitigate some harms of obesity?

Among those with brown fat, the rate of type 2 diabetes was 4.6% compared with 9.5% in those with no detected brown fat (P < .0001), and in a multivariate analysis, the odds ratio (OR) for type 2 diabetes in the presence of brown fat was 0.44.

The occurrence of coronary artery disease was significantly lower in those with brown fat (OR, 0.68; P = .0002), as was cerebrovascular disease (OR, 0.77; P = .0317), heart failure (OR, 0.62; P = .0043), and hypertension (OR, 0.85; P = .0014).

Brown fat also was associated with notable improvements in glucose, triglycerides, and HDL-C levels (all P < .0001), while no differences were seen in measures of LDL-Cs or total cholesterol.

Leukocyte and platelet counts were significantly decreased in individuals with brown fat (both P < .0001).

The findings “suggest potential roles for brown adipose beyond regulation of lipid and glucose metabolism,” the authors wrote.

Most notably, the effects were more pronounced in people with obesity. For example, the prevalence of type 2 diabetes in those with obesity and brown fat was less than half the rate in those with obesity without brown fat (7.5% vs. 20.3%; P < .0001).

This could indicate that brown adipose tissue “might play a role in mitigating the deleterious effects of obesity,” the researchers stated.

“Future research should aim to improve our understanding of brown adipose tissue regulation in humans and to develop mechanisms to safely modulate [its activity],” they concluded.

The study received funding from the American Diabetes Association, the Sinsheimer Foundation, and the National Center for Advancing Translational Sciences of the U.S. Department of Health & Human Services. The authors and Dr. Apovian have reported no relevant financial relationships.

People who have brown fat detected on imaging seem to be at reduced risk of cardiac and metabolic conditions, ranging from type 2 diabetes to hypertension and coronary artery disease, with a notably strong effect in people with obesity, according to a new study of more than 52,000 individuals who had PET/CT scans as part of cancer evaluation.

Although this has been studied for decades in newborns and animals, only in the past decade have scientists appreciated that some adults have brown fat, typically around the neck and shoulders.

The new study, by far the largest of its kind in humans, appears to confirm the health benefits of brown fat suggested by previous studies, Tobias Becher, MD, and colleagues from The Rockefeller University, New York, wrote in their article published online Jan. 4 in Nature Medicine.

“Our study indicates an important contribution of brown adipose tissue to cardiometabolic health and suggests ... [it] has therapeutic potential in humans,” they stated.

But Caroline M. Apovian, MD, Center for Weight Management and Wellness, Brigham and Women’s Hospital, Boston, is more cautious in her interpretation of the findings.

“It’s nice to see that what we believe about this is correct, and it’s great to see that with obesity and more brown fat there is reduced diabetes and hypertension, but it’s only an association,” she said in an interview.

Yet another study has linked the consumption of ultraprocessed, or “junk,” foods to bad health outcomes.

In a longitudinal analysis of more than 22,000 men and women from southern Italy, those who consumed the most ultraprocessed food (UPF) had the highest risk for cardiovascular disease (CVD) and all-cause mortality, likely mediated through a diet high in sugar, researchers said.

High consumption of UPF in this Mediterranean cohort was associated with a 58% increased risk for CVD mortality and 52% higher risk of dying from ischemic heart disease (IHD) and cerebrovascular causes, independently of known risk factors for CVD, even among individuals who otherwise adhered to the Mediterranean diet.

The findings “should serve as an incentive for limiting consumption of UPF and encouraging natural or minimally processed foods, as several national nutritional policies recommend,” Marialaura Bonaccio, PhD, department of epidemiology and prevention, IRCCS Neuromed, Pozzilli, Italy, and colleagues wrote. The results were published online Dec. 18 in the American Journal of Clinical Nutrition.

Earlier this year, as reported by this news organization, researchers found mounting evidence that the obesity epidemic and the increase in incidence of related chronic conditions corresponded with an increase in the intake of UPF.

A study that was conducted in a European cohort found that adults whose diet included more UPF and beverages, such as ice cream, soda, and hamburgers, were more likely to develop CVD or die sooner than others who had a more wholesome diet.

As reported previously by this news organization, among adults in France who had a 10% higher intake of UPF and beverages, the rate of CVD, coronary heart disease, and cerebrovascular disease was 11% to 13% higher over a period of about 5 years.

Similarly, university graduates in Spain who consumed more than four servings of UPF and beverages a day were 62% more likely to die of any cause over about a decade than those who consumed less than two servings per day.
 

Where’s the food?

There is very little actual food in UPF. “The NOVA classification provides 4 main classes of food and beverages, the last of which is represented by the ultraprocessed food group. This comprises products (e.g., snacks, drinks, and ready meals, ‘created mostly or entirely from substances extracted from foods or derived from food constituents with little, if any intact food, which often contain flavors, colors, and other additives that imitate or intensify the sensory qualities of foods or culinary preparations made from foods,’ ” Dr. Bonaccio and colleagues wrote.

Such foods are very convenient, tasty, inexpensive, and have a long shelf life. They are highly competitive with foods that are naturally ready to consume and freshly prepared dishes and meals, the authors add.

The researchers conducted a longitudinal analysis on 22,475 men and women (mean age, 55 years; range, 43-67 years) who were recruited from the Moli-sani Study, a population-based cohort of men and women aged 35 years and older in the Molise region of southern Italy, between 2005 and 2010. Participants were followed for 8.2 years.

Food intake was assessed with the Food Frequency Questionnaire; UPF was defined using the NOVA classification according to degree of processing.

UPF intakes were categorized as quartiles of the ratio of UPF to total food consumed.

Overall, study participants reported a median of 10% (interquartile range, 6.6%-14.6%) of dietary intake as UPF and a total of 181.5 g/d of UPF intake.

The foods that contributed most to total UPF consumed were processed meat, which accounted for 19.8% of UPF intake; pizza (16.8%); and cakes and pies (13.4%).

High consumers of UPF, defined as those for whom UPF constituted more than 14.6% of their total diet, were more likely to be women, to be younger, and to have a higher educational level. They also reported fewer risk factors and fewer baseline chronic diseases and health conditions than persons who consumed UPF less frequently.

In addition, high consumption of UPF was associated with lower adherence to the Mediterranean diet; higher intake of fat, sugar, dietary cholesterol, and sodium; and lower intake of fiber.

During a median follow-up of 8.2 years, 1,216 all-cause deaths occurred. Of these, 439 were attributed to CVD, 255 to IHD/cerebrovascular disease, 477 to cancer, and 300 to other causes.
 

The more UPF, the higher the risk for CVD, death

The researchers found a direct linear dose-response relation between a 5% increase in the proportion of UPF in the diet and risk for all-cause and CVD mortality.

Individuals who reported the highest intake of UPF (fourth quartile, 14.6% of total food) as opposed to the lowest (first quartile, UPF <6.6%) experienced increased risks for CVD mortality (hazard ratio, 1.58; 95% CI, 1.23-2.03), death from IHD/cerebrovascular disease (HR, 1.52, 95% CI, 1.10-2.09), and all-cause mortality (HR, 1.26; 95% CI, 1.09-1.46).

High sugar content accounted for 36.3% of the relation of UPF with IHD/cerebrovascular mortality. Other nutritional factors, such as saturated fats, were unlikely to play a role, the researchers wrote.

Biomarkers of renal function accounted for 20.1% of the association of UPF with all-cause mortality and 12.0% for that of UPF with CVD mortality.

Subgroup analyses indicated that the magnitude of the association between UPF and all-cause mortality risk was greater among high-risk individuals, such as those with a history of CVD or diabetes. UPF was also likely to be more strongly associated with CVD mortality among those high-risk groups.

The interesting finding that the association between UPF and CVD mortality was greater among individuals with good adherence to the Mediterranean diet, which is known to have health benefits, could be explained by the fact that people who may benefit from a Mediterranean diet are more susceptible to losing health advantages when they also include “detrimental dietary behavior,” whereas those who consume a poor-quality diet are less likely to be harmed by an additional unhealthy behavior such as eating UPF regularly, wrote Dr. Bonaccio and colleagues.

“This is an interesting study confirming that consumption of highly processed foods such as pizza, processed meats, and soda are associated with greater risks of cardiovascular disease,” Walter Willett, MD, professor of epidemiology and nutrition, Harvard School of Public Health, Boston, said in an interview.

“These higher risks appear to be mediated in part by high intakes of saturated fat and sugar, but lower intakes of health-promoting aspects of diet also likely contribute to the findings,” Dr. Willett said.

“Some processing of food can be useful for preservation and control of infectious agents, but in general, a diet emphasizing minimally processed fruits and vegetables, whole grains, nuts, legumes, and plant sources of fat will be best for long-term well-being,” he said.

The study was supported in part by the Italian Ministry of Health and the HYPERCAN Study Italian Association for Cancer Research. Dr. Bonaccio and Dr. Willett reported no relevant financial relationships.

Overall, study participants reported a median of 10% (interquartile range, 6.6%-14.6%) of dietary intake as UPF and a total of 181.5 g/d of UPF intake.

The foods that contributed most to total UPF consumed were processed meat, which accounted for 19.8% of UPF intake; pizza (16.8%); and cakes and pies (13.4%).

High consumers of UPF, defined as those for whom UPF constituted more than 14.6% of their total diet, were more likely to be women, to be younger, and to have a higher educational level. They also reported fewer risk factors and fewer baseline chronic diseases and health conditions than persons who consumed UPF less frequently.

In addition, high consumption of UPF was associated with lower adherence to the Mediterranean diet; higher intake of fat, sugar, dietary cholesterol, and sodium; and lower intake of fiber.

During a median follow-up of 8.2 years, 1,216 all-cause deaths occurred. Of these, 439 were attributed to CVD, 255 to IHD/cerebrovascular disease, 477 to cancer, and 300 to other causes.
 

The more UPF, the higher the risk for CVD, death

The researchers found a direct linear dose-response relation between a 5% increase in the proportion of UPF in the diet and risk for all-cause and CVD mortality.

Individuals who reported the highest intake of UPF (fourth quartile, 14.6% of total food) as opposed to the lowest (first quartile, UPF <6.6%) experienced increased risks for CVD mortality (hazard ratio, 1.58; 95% CI, 1.23-2.03), death from IHD/cerebrovascular disease (HR, 1.52, 95% CI, 1.10-2.09), and all-cause mortality (HR, 1.26; 95% CI, 1.09-1.46).

High sugar content accounted for 36.3% of the relation of UPF with IHD/cerebrovascular mortality. Other nutritional factors, such as saturated fats, were unlikely to play a role, the researchers wrote.

Biomarkers of renal function accounted for 20.1% of the association of UPF with all-cause mortality and 12.0% for that of UPF with CVD mortality.

Subgroup analyses indicated that the magnitude of the association between UPF and all-cause mortality risk was greater among high-risk individuals, such as those with a history of CVD or diabetes. UPF was also likely to be more strongly associated with CVD mortality among those high-risk groups.

The interesting finding that the association between UPF and CVD mortality was greater among individuals with good adherence to the Mediterranean diet, which is known to have health benefits, could be explained by the fact that people who may benefit from a Mediterranean diet are more susceptible to losing health advantages when they also include “detrimental dietary behavior,” whereas those who consume a poor-quality diet are less likely to be harmed by an additional unhealthy behavior such as eating UPF regularly, wrote Dr. Bonaccio and colleagues.

“This is an interesting study confirming that consumption of highly processed foods such as pizza, processed meats, and soda are associated with greater risks of cardiovascular disease,” Walter Willett, MD, professor of epidemiology and nutrition, Harvard School of Public Health, Boston, said in an interview.

“These higher risks appear to be mediated in part by high intakes of saturated fat and sugar, but lower intakes of health-promoting aspects of diet also likely contribute to the findings,” Dr. Willett said.

“Some processing of food can be useful for preservation and control of infectious agents, but in general, a diet emphasizing minimally processed fruits and vegetables, whole grains, nuts, legumes, and plant sources of fat will be best for long-term well-being,” he said.

The study was supported in part by the Italian Ministry of Health and the HYPERCAN Study Italian Association for Cancer Research. Dr. Bonaccio and Dr. Willett reported no relevant financial relationships.

Millions of Americans with treatment-resistant hypertension are likely not being tested to determine whether their high blood pressure is driven by primary aldosteronism (PA), despite guidelines that call for such an approach, according to findings from the first reported large-scale, multicenter study of PA testing practices.

Researchers ran a retrospective review of PA testing among 269,010 patients who met the definition as having treatment-resistant hypertension and were managed at any one of 130 Veterans Health Administration (VHA) medical centers from 2000 to 2017.

The results showed that, despite the fact that primary aldosteronism is highly prevalent among patients with treatment-resistant hypertension, only 4,277 (1.6%) underwent assessment for PA during a median of 3.3 years’ follow-up after they first met the defining criteria, Jordana B. Cohen, MD, and her associates reported in a study published in Annals of Internal Medicine on December 28.

“Testing rates also did not change meaningfully over nearly 2 decades ... despite an increasing number of guidelines recommending testing for primary aldosteronism in this population,” including the most recent recommendations from the Endocrine Society, issued in 2016, noted Dr. Cohen, a nephrologist and hypertension researcher at the University of Pennsylvania in Philadelphia, and colleagues.

Most patients in the study (almost 90%) were seen by a primary care practitioner (PCP).

The small percentage of patients seen by a nephrologist or endocrinologist were more than twice as likely to be tested for PA than those seen by a PCP or cardiologist.

Those clinicians who did order a test for PA were much more likely to treat patients with the appropriate medication, a mineralocorticoid receptor antagonist (MRA). In addition, therapy was started sooner, the researchers found.

“Our results corroborate” earlier reports from smaller health systems and suggest that dramatic underuse of PA assessment “is an issue across the US,” Dr. Cohen said in an interview.

The VHA experience “is very representative of what we think goes on across U.S. practice” and contrasts with the VHA’s reputation for “doing a pretty good job managing hypertension” in general, she noted.
 

Missed diagnosis, missed treatment

Dr. Cohen believes a number of factors likely help drive the abysmally low rate of PA testing they observed in the VHA system. She believes rates of PA testing are low elsewhere as well.

First, optimal hypertension management “is often taken for granted” but is challenging in busy primary care practices, so many of patients likely fall through the cracks, she said.

Dr. Cohen cited efforts at her institution, as well as by the VHA system, to better employ electronic health records to flag patients with treatment-resistant hypertension – defined as patients whose systolic or diastolic blood pressure remains at or above 140/90 mm Hg on at least two successive measurements at least a month apart while the patient is undergoing treatment with three conventional antihypertensive drugs – and to guide clinicians to order the right tests and treatments for these patients.

Many care providers mistakenly “see treatment-resistant hypertension as a disease of noncompliance,” although it is much more often the result of a missed diagnosis and inadequate intervention, she explained.
 

Physicians in denial; side effects of MRAs may deter prescribing

A second big cause of low PA testing rates is that doctors make the mistake of thinking a PA test result won’t change how they manage these patients.

The established treatment for most patients with treatment-resistant hypertension as well as PA is adding an MRA, either spironolactone or eplerenone (Inspra).

Many providers cling to the belief that they will start an MRA in these patients without first determining their PA status, says Dr. Cohen, but the data she and her colleagues collected show the opposite.

Overall, about 13% of all patients in the study began treatment with an MRA during follow-up. The likelihood of starting treatment with this drug class was fourfold higher among the patients tested for PA compared with those who were not tested.

PA testing also hastened the start of MRA use by more than a year, compared with untested patients.

“Providers think they prescribe an MRA” to treatment-resistant patients, “but it’s part of their denial. They are not using the evidence-based treatments [spironolactone or eplerenone], perhaps because of concerns about MRA side effects, although those have been pretty well overcome during the past 20 years,” she observed.

Dr. Cohen says gynecomastia is one adverse effect that gives pause to VHA clinicians who see a heavily male patient population. “It’s probably the biggest concern and why PA testing and MRA use is low” in the VHA system, she said.

“You can use a lower dosage of spironolactone, and the incidence is less common with eplerenone,” although using eplerenone does not completely eliminate all gynecomastia cases, she noted.

At the University of Pennsylvania hospitals, men often start on spironolactone first because it retains a significant price advantage, even though eplerenone is now generic, but “if there is a hint of gynecomastia, we quickly switch to eplerenone, which is usually well tolerated,” she explained.

And while eplerenone has a reputation of being less effective than spironolactone, “I’ve prescribed a lot of eplerenone and have had good results,” Dr. Cohen said. “Even if the blood pressure lowering is not as great compared with spironolactone, it still blunts the toxic effects of aldosterone on target organs.”

Hyperkalemia is the other big concern about spironolactone and eplerenone. Both agents cause it at roughly the same rate, although the rate is lower in patients without chronic kidney disease.

A new, nonsteroidal MRA, finerenone, caused substantially less hyperkalemia in a recent phase 3 trial, FIDELIO-DKD, and as a nonsteroidal MRA, it does not cause gynecomastia. Finerenone has promise as a potentially safer option for treating PA and treatment-resistant hypertension, noted Cohen, but so far, no advanced clinical trials have been launched to examine its efficacy for these indications.
 

PA testing allows a surgical option

A third reason to test patients with treatment-resistant hypertension for PA is that jumping straight to MRA treatment denies the patient assessment for a unilateral adrenal adenoma as the cause of excess aldosterone.

When unilateral adenomas exist, patients are candidates for adrenalectomy. Despite the potential advantage this gives patients to eliminate the cause of their PA without the need for additional drug treatment, some clinicians don’t see this as a compelling rationale to test for PA because they have a bias against surgery or have seen too many cases in which surgery failed to produce full hypertension resolution.

“It’s all about setting expectations appropriately” for the impact of this surgery, Dr. Cohen said.

“Adrenalectomy is not a cure; it just gets rid of the source of excess aldosterone.” But in patients with long-standing PA and hypertension, this is often not enough to completely resolve entrenched cardiovascular pathology.
 

PCPs, cardiologists in rural locations least likely to order PA testing

Of the 269,010 patients analyzed by Dr. Cohen and her coauthors, the average age was 65 years; 96% were men; half were obese; and 40% had diabetes. The researchers excluded patients who had already been tested for PA, as well as those who were already receiving treatment with an MRA.

For 88% of the patients, the main physician overseeing care was a PCP. A cardiologist was the main physician for 10%; a nephrologist, for 1%; and an endocrinologist, for fewer than 1%.

The rate of testing for PA varied across the 130 VHA centers that contributed data, ranging from 0% to 6%. The testing data showed that endocrinologists were most likely to order PA testing, doing it 2.48-fold more often than PCPs. Nephrologists were roughly twice as likely to order PA testing than PCPs, and cardiologists ordered testing at about the same rate as PCPs.

Patients managed at VHA centers in rural locations were nearly half as likely to undergo testing as patients managed at nonrural centers. The number of patients with treatment-resistant hypertension seen by a physician or at a center had no significant relationship to PA testing frequency.

The study received no commercial funding. Dr. Cohen has disclosed no relevant financial relationships.

The U.S. Food and Drug Administration has approved the first-ever generic glucagon injection kit for the treatment of severe hypoglycemia in patients with diabetes and as a diagnostic aid.

The FDA determined that Amphastar’s Glucagon for Injection Emergency Kit, 1 mg, a synthetic peptide product, is bioequivalent and therapeutically equivalent to Eli Lilly’s recombinant DNA Glucagon Emergency Kit for Low Blood Sugar.

Both require a multistep mixing process that means they are complicated to use.

In 2019, FDA approved two branded, easier-to-use formulations of glucagon – one nasally administered (Baqsimi, Eli Lilly & Co) and the other a prefilled pen or syringe (Gvoke HypoPen and Gvoke PFS, respectively, Xeris Pharmaceuticals).

The new generic will have the advantage of lower cost, Amphastar spokesman Dan Dischner said in an interview.

“Our generic glucagon will be priced as a generic product so that patients will benefit from a lower price. As we are just at the beginning of the commercialization of the product, we are unable to discuss our specific product price,” he wrote.

As with the branded Lilly injectable glucagon, the new generic is also indicated as a diagnostic aid in gastrointestinal radiologic imaging, as glucagon slows gastric motility.

According to an FDA statement, glucagon is a “complex product” that has been difficult to manufacture generically despite the lifting of patent protection. This approval was the result of the FDA’s efforts to encourage the development and submission of applications for such drugs.

Amphastar specializes in “developing, manufacturing, marketing, and selling technically-challenging generic and proprietary injectable, inhalation, and intranasal products,” the company website says.

Mr. Dischner said, “Glucagon is a complex product that requires R&D and manufacturing capabilities to develop a highly purified synthetic peptide product bioequivalent and therapeutically equivalent to the recombinant DNA origin Glucagon. Given that this product has been through various review cycles, its complexity, and the technological capabilities required to manufacture, it is no surprise that there hasn’t been a generic of glucagon until now.”

Side effects of injected glucagon include nausea, vomiting, transient increase in heart rate, and redness/swelling of the injection site.

Mr. Dischner added, “We are confident that our generic to Lilly’s time-tested glucagon will provide a favorable option, at a reasonable price, to patients who rely on this product.”

Mr. Dischner said, “Glucagon is a complex product that requires R&D and manufacturing capabilities to develop a highly purified synthetic peptide product bioequivalent and therapeutically equivalent to the recombinant DNA origin Glucagon. Given that this product has been through various review cycles, its complexity, and the technological capabilities required to manufacture, it is no surprise that there hasn’t been a generic of glucagon until now.”

Side effects of injected glucagon include nausea, vomiting, transient increase in heart rate, and redness/swelling of the injection site.

Mr. Dischner added, “We are confident that our generic to Lilly’s time-tested glucagon will provide a favorable option, at a reasonable price, to patients who rely on this product.”

The Food and Drug Administration has approved the EndoRotor System (Interscope, Inc.) for removal of necrotic tissue in patients with walled-off pancreatic necrosis (WOPN).

“This device has shown its potential to provide a minimally invasive way to remove harmful necrotic pancreatic tissue in patients with walled-off pancreatic necrosis,” Charles Viviano, MD, PhD, acting director, Reproductive, Gastro-Renal, Urological, General Hospital Device and Human Factors Office, FDA Center for Devices and Radiological Health, said in a statement.

“Currently, in order to remove dead tissue from a patient’s necrotic pancreatic cavity, health care providers need to perform an invasive surgery or use other endoscopic tools not specifically indicated to treat this condition. With [this] marketing authorization, patients with walled-off pancreatic necrosis now have a new treatment option,” said Dr. Viviano.

WOPN is a potentially deadly condition that occurs in about 15% of patients with severe pancreatitis. Often, the dead tissue must be removed.

The EndoRotor System is made up of a power console, foot control, specimen trap, and single-use catheter.

The device is used to perform endoscopic necrosectomy. In this procedure, a stent is used to create a portal between the stomach and the necrotic cavity in the pancreas to accommodate a standard endoscope through which the EndoRotor cuts and removes necrotized tissue.

The FDA approved the EndoRotor System on the basis of a clinical trial involving 30 patients with WOPN who underwent a total of 63 direct endoscopic necrosectomies with the EndoRotor System (average, 2.1 procedures per patient).

The effectiveness of the EndoRotor System was determined by how well it cleared pancreatic necrotic tissue measured during CT with contrast before and after the procedure, endoscopy, or MRI 14 to 28 days after the last procedure.

Results showed an average 85% reduction in the amount of necrotic tissue, with half of the patients having 98.5% clearance of necrotic tissue, the FDA said.

Three patients suffered procedure-related serious adverse events (10% complication rate). Two patients experienced gastrointestinal bleeding. One patient had a pneumoperitoneum and later died after suffering from sepsis and multiorgan system failure caused by massive collections of infected pancreatic necrotic tissue.

Other serious adverse events, which were thought to be due to the patient’s underlying condition and not related to the device or procedure, included hematemesis, deep vein thrombosis, and pancreatitis.

The EndoRotor System should not be used for patients with known or suspected pancreatic cancer, and the device will carry a boxed warning stating this.

The FDA said it knows of one patient who died from pancreatic cancer 3 months after having necrotic pancreatic tissue removed with the EndoRotor System.

“This patient did not have a diagnosis of pancreatic cancer prior to treatment, although the patient’s outcome is believed to be unrelated to the device or procedure,” the FDA said.

The EndoRotor System should be used only after patients have undergone other procedures to drain the WOPN.

It is also not appropriate for patients with walled-off necrosis who have a documented pseudoaneurysm greater than 1 cm within the cavity or with intervening gastric varices or unavoidable blood vessels within the access tract.

The EndoRotor System was approved under the de novo premarket review pathway for new low- to moderate-risk devices.
