New guidance is available for managing inpatient hyperglycemia and diabetic ketoacidosis (DKA) in COVID-19 patients with diabetes using subcutaneous insulin.

“The glycemic management of many COVID-19–positive patients with diabetes is proving extremely complex, with huge fluctuations in glucose control and the need for very high doses of insulin,” says Diabetes UK’s National Diabetes Inpatient COVID Response Team.

“Intravenous infusion pumps, also required for inotropes, are at a premium and there may be the need to consider the use of subcutaneous or intramuscular insulin protocols,” they note.

Updated as of April 29, all of the information of the National Diabetes Inpatient COVID Response Team is available on the Diabetes UK website.

The new inpatient management graphic adds more detail to the previous “front-door” guidance, as reported by Medscape Medical News.

The document stressed that, as well as identifying patients with known diabetes, it is imperative that all newly admitted patients with COVID-19 are evaluated for diabetes, as the infection is known to cause new-onset diabetes.
 

Subcutaneous insulin dosing

The new graphic gives extensive details on subcutaneous insulin dosing in place of variable rate intravenous insulin when infusion pumps are not available, and when the patient has a glucose level above 12 mmol/L (216 mg/dL) but does not have DKA or hyperosmolar hyperglycemic state.

However, the advice is not intended for people with COVID-19 causing severe insulin resistance in the intensive care unit.

The other new guidance graphic on managing DKA or hyperosmolar state in people with COVID-19 using subcutaneous insulin is also intended for situations where intravenous infusion isn’t available.
 

Seek help from specialist diabetes team when needed

This is not to be used for mixed DKA/hyperosmolar state or for patients who are pregnant, have severe metabolic derangement, other significant comorbidity, or impaired consciousness, however.

For those situations, the advice is to seek help from a specialist diabetes team, says Diabetes UK.

Specialist teams will be available to answer diabetes queries, both by signposting to relevant existing local documents and also by providing patient-specific advice.

Indeed, NHS England recommends that such a team be available in every hospital, with a lead consultant designated each day to co-ordinate these services who must be free of other clinical duties when doing so. The role involves co-ordination of the whole service from the emergency department through to liaison with other specialties and managers.

Also newly updated is a page with extensive information for patients, including advice for staying at home, medication use, self-isolating, shielding, hospital and doctor appointments, need for urgent medical advice, and going to the hospital.

It also covers how coronavirus can affect people with diabetes, children and school, pregnancy, work situations, and tips for picking up prescriptions.

Another, shorter document with COVID-19 advice for patients has been posted by the JDRF and Beyond Type 1 Alliance.

It has also been endorsed by the American Diabetes Association, Harvard Medical School, and International Society for Pediatric and Adolescent Diabetes, in partnership with many other professional organizations, including the International Diabetes Federation, American Association of Clinical Endocrinologists, and Association of Diabetes Care & Education Specialists.

The shorter document covers topics such as personal hygiene, distancing, diabetes management, and seeking treatment, as well as links to other resources on what to do when health insurance is lost and legal rights.

FDA approves dapagliflozin for low-EF heart failure

Article Type

Tue, 05/03/2022 - 15:10

The Food and Drug Administration has come through with the widely anticipated approval of dapagliflozin (Farxiga, AstraZeneca) for heart failure and reduced ejection fraction (HFrEF), adding to the rich array of medications lately available for this indication.

The approval follows the agency’s priority review of the sodium-glucose cotransporter 2 (SGLT2) inhibitor for reducing the risk of cardiovascular death and heart-failure hospitalization in adults with HFrEF following last year’s seminal results of the DAPA-HF trial.

In that study, treatment with dapagliflozin led to about a one-fourth reduction in risk of a primary endpoint consisting primarily of CV death or heart failure hospitalization in patients with chronic HFrEF, in both those with and without diabetes. The randomized, placebo-controlled trial had entered more than 4,700 patients.

Soon after, the FDA approved dapagliflozin for reducing the risk of heart failure hospitalization in adults with type 2 diabetes and other CV risk factors.



And of course, dapagliflozin – traditionally viewed only as an antidiabetic agent – has long been indicated for improvement of glycemic control in adults with type 2 diabetes.

The latest approval for patients with New York Heart Association functional class III-IV HFrEF makes dapagliflozin the only SGLT2 inhibitor to be indicated for heart failure in the absence of diabetes.

Soon after the DAPA-HF results had been unveiled at a major meeting, heart failure expert Christopher O’Connor, MD, expressed concern that dapagliflozin’s uptake for patients with HFrEF would be slow once it gained approval for patients without diabetes.

“We have to think of this as a drug that you would prescribe like an ACE inhibitor, or a beta-blocker, or a mineralocorticoid receptor antagonist, or sacubitril/valsartan [Entresto, Novartis],” Dr. O’Connor, of the Inova Heart and Vascular Institute, Falls Church, Va., said in an interview.

Dr. O’Connor was not associated with DAPA-HF and had previously disclosed no relevant financial relationships.

New study of diabetes drug for COVID-19 raises eyebrows

Article Type
Changed
Tue, 05/03/2022 - 15:10

 

A just-launched study of the type 2 diabetes agent dapagliflozin (Farxiga, AstraZeneca) in patients with mild to moderate COVID-19 is raising eyebrows, given that several expert groups have advised that drugs in this class – the sodium-glucose cotransporter 2 (SGLT2) inhibitors – be stopped in all patients hospitalized with COVID-19 because of the increased risk for diabetic ketoacidosis (DKA).

The randomized, double-blind, placebo-controlled, phase 3 Dapagliflozin in Respiratory Failure in Patients With COVID-19 (DARE-19) study is sponsored by AstraZeneca and Saint Luke’s Mid America Heart Institute.

The trial will assess whether dapagliflozin reduces the risks of disease progression, clinical complications, and death because of COVID-19 in patients with type 2 diabetes, cardiovascular disease, and/or mild to moderate chronic kidney disease (CKD).

“Dapagliflozin has demonstrated cardio- and renal-protective benefits and improved outcomes in high-risk patients with type 2 diabetes, heart failure with reduced ejection fraction, and CKD,” said the principal investigator of DARE-19, Mikhail N. Kosiborod, MD, a cardiologist at Saint Luke’s Mid America Heart Institute, Kansas City, Mo.

And “patients with COVID-19 and underlying cardiometabolic disease appear to be at the highest risk of morbid complications,” he explained in an AstraZeneca statement.

“Through DARE-19, we hope to decrease the severity of illness, and prevent cardiovascular, respiratory, and kidney decompensation, which are common in patients with COVID-19,” Dr. Kosiborod continued.

However, advice to stop SGLT2 inhibitors in patients hospitalized with COVID-19 because of its associated DKA risk has come from several channels.

These include initial guidance from Diabetes UK; experts who spoke during an American Diabetes Association webinar; and most recently, an international panel of diabetes experts.

Some clinicians went so far as to say that they view the trial as potentially dangerous, while others said they could see some logic to it, as long as it is carefully managed.
 

“A dangerous proposition – a DARE I would not take”

Partha Kar, MD, of Portsmouth Hospitals NHS Trust and national clinical director of diabetes at NHS England, said in an interview: “It’s interesting to see [AstraZeneca] embark on a study with a particular class of drug whereby ... [in] the UK we have said that if you get sent to hospital with COVID-19 you should stop [SGLT2 inhibitors] immediately.”

It “sounds like a risky proposition to go ahead with, [and it] definitely made me raise an eyebrow,” he added.

Nephrologist Bruce R. Leslie, MD, of Seventh Doctor Consulting in Princeton, N.J., agreed with Dr. Kar.

“Giving SGLT2 inhibitors to patients in the DARE-19 study is a dangerous proposition because these drugs can induce ketoacidosis during the stress of acute illness such as COVID-19. ... Moreover, ketoacidosis is associated with hypercoagulability which could be especially dangerous in COVID-19, given that it has been causing thrombophilia with large-vessel occlusive strokes in young patients,” he said in an interview.

“One wonders how these risks were assessed by the authorities that approved the DARE-19 study,” said Dr. Leslie, who formerly worked for Bristol-Myers Squibb.

“How does the sponsor intend to secure informed consent given the risks? This is a DARE I would not take,” he said.

Asked to address these concerns, Dr. Kosiborod said in an interview that “the DARE-19 trial will assess both the efficacy and the safety of dapagliflozin in this patient population in a closely monitored environment of a rigorously designed randomized clinical trial. The trial protocol excludes patients with type 1 diabetes or at high risk for DKA.

“Furthermore, the protocol includes detailed specific instructions to ensure careful monitoring for DKA, including frequent assessments of acid-base status in the hospital setting. The safety data will be closely monitored by an independent data-monitoring committee,” he continued.

Dr. Kosiborod also pointed out that there is “no systematically collected information on the use of dapagliflozin or any other SGLT2 inhibitor in patients being treated for COVID-19, including the associated potential benefits, possible risks such as DKA, and the balance of these potential benefits and risks.”

 

 

DARE-19 design: Several outcomes will be examined

The DARE-19 trial is designed to enroll 900 adults with confirmed SARS-CoV-2 infection and oxygen saturation of 94% or greater.

Inclusion criteria include a medical history of hypertension, type 2 diabetes, atherosclerotic cardiovascular disease, heart failure, and/or stage 3-4 CKD. Exclusion criteria include current SGLT2 inhibitor treatment, type 1 diabetes, severe CKD, and severe COVID-19.

Dapagliflozin is approved in the EU for use in some patients with type 1 diabetes; this is not the case in the United States, although SGLT2 inhibitors in general are sometimes used off label in these patients.

Patients in DARE-19 will be randomized to 10 mg/day dapagliflozin or placebo for 30 days, in addition to standard care, in participating hospital. Primary outcomes are time to first occurrence of either death or new or worsened organ dysfunction, including respiratory decompensation, new or worsening heart failure, requirement for vasopressor therapy, ventricular tachycardia, and renal failure.

Secondary outcomes include a composite of time to death from any cause, time to new/worsened organ dysfunction, clinical status at day 30, and time to hospital discharge.

Rationale for the study

Irl B. Hirsch, MD, professor and diabetes treatment and teaching chair at the University of Washington, Seattle, said in an interview that he does see some logic to the trial.

Admitting that he doesn’t know much about “COVID-19 cardiomyopathy” – which would be one of the targets of dapagliflozin – other than it is quite common, he said that this, along with the potential renal benefits of dapagliflozin in the setting of COVID-19, make the study “intriguing.”

“Perhaps there is some rationale to it,” he said. However, “my concern is these sick COVID-19 patients are often acidemic, and besides the very complex acid-base challenges we see with intubated patients, these patients likely have combination lactic and ketoacidemia, the latter at least some from starvation.

“Still, if enough dextrose and insulin are provided to prevent ketoacid accumulation, my guess is it would do at least as well as hydroxychloroquine,” he said.

And Simon Heller, MD, professor of clinical diabetes at the University of Sheffield (England), said in an interview: “I think it is quite a brave study, mainly because of the increased risk of DKA.

“However, on the basis that these patients will be carefully monitored, the risk of DKA shouldn’t be great. I think it is important that patients with type 2 diabetes can participate whenever possible in such trials,” he said.

The estimated completion date for DARE-19 is December 2020.

Dr. Kosiborod has reported receiving grant support, honoraria, and/or research support from AstraZeneca, Boehringer Ingelheim, Sanofi, Amgen, Novo Nordisk, Merck, Eisai, Janssen, Bayer, GlaxoSmithKline, Glytec, Intarcia Therapeutics, Novartis, Applied Therapeutics, Amarin, and Eli Lilly. Dr. Leslie has reported owning stock in Bristol-Myers Squibb, Pfizer, and Lilly. Dr. Hirsch has reported consulting for Abbott Diabetes Care, Roche, and Bigfoot Biomedical, conducting research for Medtronic, and is a diabetes editor for UpToDate. Dr. Heller has received advisory or consultation fees from Lilly, Novo Nordisk, Takeda, MSD, and Becton Dickinson; has served as a speaker for AstraZeneca, Lilly, Novo Nordisk, Boehringer Ingelheim, and Takeda; and has received research support from Medtronic UK. He is on the advisory board for Medscape. Dr. Kar has reported no relevant financial relationships.

“A dangerous proposition – a DARE I would not take”

Partha Kar, MD, of Portsmouth Hospitals NHS Trust and national clinical director of diabetes at NHS England, said in an interview: “It’s interesting to see [AstraZeneca] embark on a study with a particular class of drug whereby ... [in] the UK we have said that if you get sent to hospital with COVID-19 you should stop [SGLT2 inhibitors] immediately.”

It “sounds like a risky proposition to go ahead with, [and it] definitely made me raise an eyebrow,” he added.

Nephrologist Bruce R. Leslie, MD, of Seventh Doctor Consulting in Princeton, N.J., agreed with Dr. Kar.

“Giving SGLT2 inhibitors to patients in the DARE-19 study is a dangerous proposition because these drugs can induce ketoacidosis during the stress of acute illness such as COVID-19. ... Moreover, ketoacidosis is associated with hypercoagulability which could be especially dangerous in COVID-19, given that it has been causing thrombophilia with large-vessel occlusive strokes in young patients,” he said in an interview.

“One wonders how these risks were assessed by the authorities that approved the DARE-19 study,” said Dr. Leslie, who formerly worked for Bristol-Myers Squibb.

“How does the sponsor intend to secure informed consent given the risks? This is a DARE I would not take,” he said.

Asked to address these concerns, Dr. Kosiborod said in an interview that “the DARE-19 trial will assess both the efficacy and the safety of dapagliflozin in this patient population in a closely monitored environment of a rigorously designed randomized clinical trial. The trial protocol excludes patients with type 1 diabetes or at high risk for DKA.

“Furthermore, the protocol includes detailed specific instructions to ensure careful monitoring for DKA, including frequent assessments of acid-base status in the hospital setting. The safety data will be closely monitored by an independent data-monitoring committee,” he continued.

Dr. Kosiborod also pointed out that there is “no systematically collected information on the use of dapagliflozin or any other SGLT2 inhibitor in patients being treated for COVID-19, including the associated potential benefits, possible risks such as DKA, and the balance of these potential benefits and risks.”

 

 

DARE-19 design: Several outcomes will be examined

The DARE-19 trial is designed to enroll 900 adults with confirmed SARS-CoV-2 infection and oxygen saturation of 94% or greater.

Inclusion criteria include a medical history of hypertension, type 2 diabetes, atherosclerotic cardiovascular disease, heart failure, and/or stage 3-4 CKD. Exclusion criteria include current SGLT2 inhibitor treatment, type 1 diabetes, severe CKD, and severe COVID-19.

Dapagliflozin is approved in the EU for use in some patients with type 1 diabetes; this is not the case in the United States, although SGLT2 inhibitors in general are sometimes used off label in these patients.

Patients in DARE-19 will be randomized to 10 mg/day dapagliflozin or placebo for 30 days, in addition to standard care, in participating hospital. Primary outcomes are time to first occurrence of either death or new or worsened organ dysfunction, including respiratory decompensation, new or worsening heart failure, requirement for vasopressor therapy, ventricular tachycardia, and renal failure.

Secondary outcomes include a composite of time to death from any cause, time to new/worsened organ dysfunction, clinical status at day 30, and time to hospital discharge.

Rationale for the study

Irl B. Hirsch, MD, professor and diabetes treatment and teaching chair at the University of Washington, Seattle, said in an interview that he does see some logic to the trial.

Admitting that he doesn’t know much about “COVID-19 cardiomyopathy” – which would be one of the targets of dapagliflozin – other than it is quite common, he said that this, along with the potential renal benefits of dapagliflozin in the setting of COVID-19, make the study “intriguing.”

“Perhaps there is some rationale to it,” he said. However, “my concern is these sick COVID-19 patients are often acidemic, and besides the very complex acid-base challenges we see with intubated patients, these patients likely have combination lactic and ketoacidemia, the latter at least some from starvation.

“Still, if enough dextrose and insulin are provided to prevent ketoacid accumulation, my guess is it would do at least as well as hydroxychloroquine,” he said.

And Simon Heller, MD, professor of clinical diabetes at the University of Sheffield (England), said in an interview: “I think it is quite a brave study, mainly because of the increased risk of DKA.

“However, on the basis that these patients will be carefully monitored, the risk of DKA shouldn’t be great. I think it is important that patients with type 2 diabetes can participate whenever possible in such trials,” he said.

The estimated completion date for DARE-19 is December 2020.

SGLT2 inhibitor ertugliflozin shows no CV death or renal benefit

Tue, 05/03/2022 - 15:10

The sodium-glucose transporter 2 (SGLT-2) inhibitor ertugliflozin broke ranks with the other drugs in its class and failed to produce statistically significant drops in the both the combined incidence of cardiovascular (CV) death or heart failure hospitalization, and the rate of adverse renal outcomes, in the mandated CV outcomes trial run for ertugliflozin with more than 8,200 patients with type 2 diabetes and established CV disease.

Merck, one of the companies that markets the drug, announced the topline results in a quarterly financial report released on April 28, 2020.

According to the report, the results from the ertugliflozin cardiovascular outcomes trial “achieved its primary endpoint of noninferiority for major adverse CV events (MACE), compared to placebo in patients with type 2 diabetes mellitus and established atherosclerotic CV disease,” but “the key secondary endpoints of superiority” of ertugliflozin, compared with placebo, “for time to the composite of CV death or hospitalization for heart failure, CV death alone, and the composite of renal death, dialysis/transplant or doubling of serum creatinine from baseline were not met.”

However, the report added that, “while not a prespecified hypothesis for statistical testing, a reduction in hospitalization for heart failure was observed” with ertugliflozin treatment, and the report further said that the drug’s safety profile in the trial “was consistent with that reported in previous studies.” The statement closed by saying that detailed results from the trial are scheduled to be presented on June 16, 2020, at the virtual American Diabetes Association’s 80th Scientific Sessions.



These results came from the VERTIS CV (Evaluation of Ertugliflozin EffIcacy and Safety Cardiovascular Outcomes) trial, which researchers said in 2018 had administered at least one investigational dose to 8,238 randomized patients at centers in any of 34 countries during two enrollment periods in 2013-2015 and 2016-2017 (Am Heart J. 2018 Dec;206:11-23). The tested agent, ertugliflozin (Steglatro) received Food and Drug Administration marketing approval late in 2017 for the indication of improving glycemic control in patients with type 2 diabetes.

The FDA mandated cardiovascular outcomes trials for new glycemic control drugs in guidance the agency issued in 2008 (the FDA released in March 2020 a draft of updated guidance on this topic).

Other FDA-approved agents from the SGLT2 inhibitor class include canagliflozin (Invokana), dapagliflozin (Farxiga), and empagliflozin (Jardiance), and all three showed evidence for a statistically significant effect on reducing the incidence of CV disease death and heart failure hospitalizations, as well as renal complications (Can J Diabetes. 2020 Feb;44[1]:61-7). The evidence showing that several SGLT2 drugs have important and consistent effects on endpoints like CV death, heart failure hospitalizations, and renal complications has helped propel this class of agents to the forefront of glycemic control treatments. More recently, one agent from this group, dapagliflozin, also significantly cut the rate of heart failure worsening or CV disease death in patients with heart failure with reduced ejection fraction but without diabetes (N Engl J Med. 2019 Nov 21;381[21]:1995-2008). Based on this evidence, the FDA is currently considering adding a new indication for dapagliflozin that would also label it for use in patients with heart failure with reduced ejection fraction but without diabetes.

Excessive sleepiness linked to heart disease, cancer, and diabetes

Article Type
Changed
Tue, 05/03/2022 - 15:10

 

Hypersomnolence, or excessive daytime sleepiness, in older adults is a risk factor for developing several serious medical conditions, including hypertension, heart disease, cancer, and diabetes, new research suggests. A study of almost 11,000 participants shows those who reported excessive sleepiness were twice as likely as their nonsleepy counterparts to develop these conditions. Hypersomnolence was also linked to development of musculoskeletal and connective tissue conditions.

“Paying attention to sleepiness in older adults could help doctors predict and prevent future medical conditions,” study investigator Maurice M. Ohayon, MD, PhD, Stanford University, California, said in a news release.

The findings were released March 1 ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology. The AAN canceled the meeting and released abstracts and access to presenters for press coverage.
 

Early warning sign

Prior research has suggested an association between hypersomnolence and several psychiatric disorders, as well as cognitive decline and Alzheimer’s disease. However, its role in the development of other medical conditions is not as well studied.

The current investigation included 10,930 adults who were interviewed by phone on two separate occasions 3 years apart. At the second interview, 3,701 participants were at least 65 years old and 59% were women.

About 23% of the elderly participants reported hypersomnolence in the first interview and 24% reported it in the second interview. Of these individuals, 41% said during the first and second interviews that excessive daytime sleepiness was a chronic problem.

After adjusting for gender and obstructive sleep apnea status, participants who reported hypersomnolence in the first interview had more than a twofold greater risk of developing diabetes (relative risk [RR], 2.3; 95% CI, 1.5 - 3.4) or hypertension (RR, 2.3; 95% CI, 1.5 - 3.4) 3 years later than those who did not report this problem. They were also twice as likely to develop cancer (RR, 2.0; 95% CI, 1.1 - 3.8).

Of the 840 participants who reported hypersomnolence at the first interview, 52 (6.2%) developed diabetes compared with 74 (2.9%) who did not have excessive daytime sleepiness. Twenty (2.4%) individuals who reported hypersomnolence developed cancer compared with 21 (0.8%) who did not have it. Chronic hypersomnolence was associated with a greater than twofold increased risk of developing heart disease (RR, 2.5; 95% CI, 1.8 - 3.4).

Those who reported hypersomnolence at the second interview also were 50% more likely to have diseases of the musculoskeletal system and connective tissue, such as arthritis, tendinitis, and lupus, than their peers who did not have excessive daytime sleepiness.

The findings suggest that hypersomnolence in the elderly “can be an early sign of a developing medical condition,” the investigators wrote.

A limitation of the study is that it relied on participants’ memories rather than monitoring their sleep length and quality and daytime sleepiness in a sleep clinic, they noted.

 

 

Sleep as a vital sign?

Commenting on the findings, Harly Greenberg, MD, medical director at the Northwell Health Sleep Disorders Center, New York City, called the study “informative.”

However, because the findings were associations, “the study does not necessarily indicate that hypersomnolence itself is causal for these conditions. Rather excessive sleepiness may be a marker of sleep disorders that can cause sleepiness as well as contribute to the risk of these medical conditions,” said Dr. Greenberg, who was not involved with the research.

“The takeaway point from this study is that excessive sleepiness should not be ignored. Not only does it impair quality of life, daytime function, and vigilance and increase risk of sleepiness-related accidents, it may also be a marker for serious sleep disorders that can increase risk for medical disorders,” he said.

Also commenting on the study, Nathaniel Watson, MD, professor of neurology at the University of Washington (UW) and director of the UW Medicine Sleep Clinic, said it is “not surprising” that excessive daytime sleepiness might contribute to diabetes, hypertension, and other diseases.

“Sleep is something we spend a third of our lives doing. It impacts nearly every aspect of human physiology and we have a lot of basic science and epidemiologic research that shows when sleep is either inadequate or of poor quality or not timed correctly it can be associated with some of these untoward health outcomes,” said Watson, who is a past president of the American Academy of Sleep Medicine.

“This research just provides further evidence in support of the importance of sleep for overall health and well-being,” he added.

Asking patients about sleepiness, sleep, or sleep quality should be a “vital sign just like temperature, blood pressure, weight, and these other measures,” Dr. Watson said.

The study was supported by the Arrillaga Foundation. Drs. Ohayon, Greenberg, and Watson have reported no relevant financial relationships.

COVID-19 cases highlight longstanding racial disparities in health care

Article Type

Tue, 05/03/2022 - 15:10

African Americans are overrepresented among patients who have died as a result of the COVID-19 pandemic, but the current crisis puts a spotlight on long-standing racial disparities in health care and health access in the United States, according to David R. Williams, PhD, a professor of public health at the Harvard T.H. Chan School of Public Health in Boston.

Dr. Williams, a social scientist specializing in the link between race and health, is a professor of African and African American Studies and of Sociology at Harvard. He spoke on the topic of racial disparities amid the COVID-19 pandemic in a teleconference sponsored by the Robert Wood Johnson Foundation.

“Many Americans are shocked” by the higher mortality rates among African American COVID-19 patients, said Dr. Williams. However, data from decades of research show that “black people in America live sicker and shorter lives,” he said.

Keys to the increased mortality among African Americans include an increased prevalence of risk factors, increased risk for exposure to the virus because of socioeconomic factors, and less access to health care if they do become ill, he said.

Many minority individuals work outside the home in areas deemed essential during the pandemic, such as transit, delivery, maintenance, cleaning, and in businesses such as grocery stores, although in general “race continues to matter for health at every level of income and education,” Dr. Williams said.

In addition, social distance guidelines are not realistic for many people in high-density, low-income areas, who often live in shared, multigenerational housing, he said.

Data show that individuals with chronic conditions such as diabetes and cardiovascular disease are more likely to die as a result of COVID-19, and minority populations are more likely to develop these conditions at younger ages, Dr. Williams noted. Access to health care also plays a role. Many minority individuals of lower socioeconomic status are less likely to have health insurance, or if they do, may have Medicaid, which is not consistently accepted, he said. Also, some low-income neighborhoods lack convenient access to primary care and thus to screening services, he noted.

Dr. Williams said the COVID-19 pandemic could serve as an opportunity to examine and improve health care services for underserved communities. In the short term, “we need to collect data so we can see patterns” and address pressing needs, he said, but long-term goals should “prioritize investments that would create healthy homes and communities,” he emphasized.

A recent study from the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report cited COVID-NET (the COVID-19 Associated Hospitalization Surveillance Network) as showing that, in their catchment population, “approximately 59% of residents are white, 18% are black, and 14% are Hispanic; however, among 580 hospitalized COVID-19 patients with race/ethnicity data, approximately 45% were white, 33% were black, and 8% were Hispanic, suggesting that black populations might be disproportionately affected by COVID-19,” the researchers said.

“These findings, including the potential impact of both sex and race on COVID-19–associated hospitalization rates, need to be confirmed with additional data,” according to the report.

Collecting racial/ethnic information is not always feasible on the front lines, and many areas still face shortages of ventilators and protective equipment, said Dr. Williams.

“I want to salute the providers on the front lines of this pandemic, many putting their own lives at risk, I want to acknowledge the good that they are doing,” Dr. Williams emphasized. He noted that all of us, himself included, may have conscious or unconscious stereotypes, but the key is to acknowledge the potential for these thoughts and feelings and continue to provide the best care.

Dr. Clyde W. Yancy


Clyde W. Yancy, MD, of Northwestern University in Chicago, expressed similar concerns about disparity in COVID-19 cases in an editorial published on April 15 in JAMA.

“Researchers have emphasized older age, male sex, hypertension, diabetes, obesity, concomitant cardiovascular diseases (including coronary artery disease and heart failure), and myocardial injury as important risk factors associated with worse outcomes,” wrote Dr. Yancy. However, evidence also suggests that “persons who are African American or black are contracting SARS-CoV-2 at higher rates and are more likely to die,” he said.

“Why is this uniquely important to me? I am an academic cardiologist; I study health care disparities; and I am a black man,” he wrote.

“Even though these data are preliminary and further study is warranted, the pattern is irrefutable: Underrepresented minorities are developing COVID-19 infection more frequently and dying disproportionately,” said Dr. Yancy.

Dr. Williams’ and Dr. Yancy’s comments were supported by an analysis of COVID-19 patient data from several areas of the country conducted by the Washington Post. In that analysis, data showed that several counties with a majority black population showed three times the rate of COVID-19 infections and approximately six times as many deaths compared with counties with a majority of white residents.

“The U.S. has needed a trigger to fully address health care disparities; COVID-19 may be that bellwether event,” said Dr. Yancy. “Certainly, within the broad and powerful economic and legislative engines of the US, there is room to definitively address a scourge even worse than COVID-19: health care disparities. It only takes will. It is time to end the refrain,” he said.

Dr. Williams had no financial conflicts to disclose. Dr. Yancy had no financial conflicts to disclose.

African Americans are overrepresented among patients who have died as a result of the COVID-19 pandemic, but the current crisis puts a spotlight on long-standing racial disparities in health care and health access in the United States, according to David R. Williams, PhD, a professor of public health at the Harvard T.H. Chan School of Public Health in Boston.

Dr. Williams, a social scientist specializing in the link between race and health, is a professor of African and African American Studies and of Sociology at Harvard. He spoke on the topic of racial disparities amid the COVID-19 pandemic in a teleconference sponsored by the Robert Wood Johnson Foundation.

“Many Americans are shocked” by the higher mortality rates among African American COVID-19 patients, said Dr. Williams. However, data from decades of research show that “black people in America live sicker and shorter lives,” he said.

Keys to the increased mortality among African Americans include an increased prevalence of risk factors, increased risk for exposure to the virus because of socioeconomic factors, and less access to health care if they do become ill, he said.

Many minority individuals work outside the home in areas deemed essential during the pandemic, such as transit, delivery, maintenance, cleaning, and in businesses such as grocery stores, although in general “race continues to matter for health at every level of income and education,” Dr. Williams said.

In addition, social distance guidelines are not realistic for many people in high-density, low-income areas, who often live in shared, multigenerational housing, he said.

Metformin use linked to improved surgery outcomes

Article Type

Tue, 05/03/2022 - 15:10

Patients with type 2 diabetes who take metformin may have lower risk-adjusted mortality and readmission rates after surgery than do those who don’t take metformin, findings from a large retrospective cohort study suggest.

Of 10,088 individuals with diabetes who underwent a major surgery requiring hospital admission between January 1, 2010, and January 1, 2016, a total of 5,962 (59%) had received a prescription for metformin in the 180 days before surgery, and 5,460 of those patients were propensity score–matched to controls who did not receive a metformin prescription.

The study participants had a mean age of 67.7 years and underwent surgery requiring general anesthesia and postoperative admission at any of 15 hospitals in a single Pennsylvania health system. In addition to being prescribed metformin within 180 days before surgery, they also had metformin on their list of active medications at their most recent preoperative encounter before the surgery. The were followed until December 18, 2018.

In all, the 90-day and 5-year mortality hazards were reduced by 28% and 26%, respectively, in the metformin prescription recipients, compared with the propensity score–matched controls (hazard ratios, 0.72 and 0.74, respectively), Katherine M. Reitz, MD, and colleagues at the University of Pittsburgh reported in JAMA Surgery.

The readmission hazard – with mortality as a competing risk – was reduced by 16% at 30 days and 14% at 90 days (sub-HRs, 0.84 and 0.86, respectively), the researchers found.

“Hospital readmissions among those with preoperative metformin prescriptions were observed by postdischarge days 30 and 90 (304 [11%] and 538 [20.1%], respectively), whereas among those without prescriptions, 361 readmissions (13%) occurred by day 30 and 614 (23%) by day 90,” they wrote.

The investigators also noted that inflammation was reduced in patients who received a metformin prescription, compared with those who did not (mean preoperative neutrophil to leukocyte ratio, 4.5 vs. 5.0, respectively).

“In the full cohort, multivariable regression analysis similarly demonstrated that metformin was associated with a reduced hazard for both 90-day and 5-year mortality (adjusted HRs, 0.77 and 0.80, respectively) and for 30-day and 90-day readmission (aHR, 0.83 and 0.86), with mortality as a competing risk,” they added.

The findings support those from previous studies showing a decrease in all-cause mortality among diabetes patients taking metformin, said the researchers, noting that those patients had fewer age-related chronic diseases.

“These associations may reflect the anti-aging properties of metformin against the onset of disease or diabetes-associated complications. This study extends these finding by demonstrating that preoperative metformin prescriptions were associated with a reduction in postoperative mortality and readmission, a surrogate for postoperative complications, and with long-term mortality,” they wrote.

The study was limited by a number of factors, such as the potential for residual confounding inherent in retrospective analyses and a lack of adequate power to evaluate the association between metformin use and outcomes for individual surgical procedures. But the authors added that the findings are of note, because adults with comorbidities, such as diabetes, have less physiological reserve and an increased postoperative mortality and readmission rate. The results, therefore, warrant investigation with a prospective randomized clinical trial, they concluded.

In an accompanying editorial, Elizabeth L. George, MD, and Sherry M. Wren, MD, of Stanford (Calif.) University wrote that the study “demonstrates how variables, besides coexisting medical diseases, can affect surgical outcomes.”

“Metformin now joins beta-blockers, statins, and immunonutrition as preoperative agents associated with improved surgical outcomes,” they wrote, adding that future studies should factor in statin use and whether those and other medications should be continued postoperatively because metformin is often held after surgery owing to concerns about contrast agent interactions, whereas statin continuation is recommended.

Future studies of metformin in this setting should exclude patients who are taking statins, or look at possible interactions between the two agents, they said, adding that they would be “interested in seeing a subanalysis of this data set that excludes patients who were prescribed statins.”

“Those data would further solidify the role of metformin as a possible modifiable perioperative factor,” they wrote.

The study was funded by the University of Pittsburgh Medical Center and by grants from the National Heart, Lung, and Blood Institute and the National Institutes of Health. Dr. Reitz reported having no disclosures. Dr. George and Dr. Wren also reported having no disclosures.

Inflammatory markers may explain COVID-19, diabetes dynamic

COVID-19 infection in patients with type 2 diabetes is associated with a greater increase in inflammatory and coagulation markers, compared with COVID-19 patients without diabetes, according to preliminary findings from a retrospective analysis of COVID-19 patients in Wuhan, China.

The results, though preliminary, could help explain why patients with diabetes and COVID-19 are at greater risk for more severe disease and death.

The results also suggest that more severe disease in patients with diabetes may be the result of a cytokine storm, in which the patient’s immune system overreacts to the virus and inflicts collateral damage on its own organs, according to Herbert I. Rettinger, MD, a clinical endocrinologist in Orange County, Calif., and member of the editorial advisory board for Clinical Endocrinology News. “Understanding the mechanism might help us understand the best way to treat,” COVID-19 in patients with diabetes, he said in an interview.

Dr. Rettinger, who was not involved in the research, noted that the study included only 24 patients with diabetes. Nevertheless, the finding of heightened inflammatory and coagulation markers was “fascinating.”

“This is the first paper I’ve seen [suggesting] that. I don’t know if we can extrapolate [the findings] to other populations, but if biomarkers are elevated in patients with COVID-19 and diabetes, then it’s something worth looking into, and to be aware of and cautious of. We need to pay attention to this,” he commented.

The study was led by Weina Guo and Desheng Hu at Huazhong University of Science and Technology in Wuhan, China, and published in Diabetes/Metabolism Research and Reviews.

The sample included 174 patients with COVID-19, who were treated consecutively during Feb. 10-29, 2020, at a single center. The researchers first assigned the patients to one of two groups – those with comorbid diabetes and those without. They further excluded all other comorbidities, focusing only on 26 patients with no comorbidities and 24 with only diabetes as a comorbidity, to remove all other comorbidities as possible confounding factors. Patients in the diabetes group were significantly older than those without diabetes (61 vs. 41 years, P < .01). The mortality rate was 16.5% in patients with diabetes and 0% in those without (P = .03).

COVID-19 patients with diabetes alone as a comorbidity had a greater risk for severe pneumonia, as evidenced by a higher mean CT score, compared with those without diabetes and no other comorbidities (P = .04). Patients with diabetes also had higher measures of release of tissue injury–related enzymes and were at higher risk of uncontrolled inflammation and hypercoagulable state. In particular, they had higher levels of interleukin-6 (13.7 vs. 4.1 pg/mL, respectively; P < .01), C-reactive protein (76.4 vs. 7.43 mg/L; P < .01), serum ferritin (764.8 vs. 128.9 ng/mL; P < .01), and D-dimer (1.16 vs. 0.25 mcg/mL; P < .01).

“It’s noteworthy that, for diseases that can induce a cytokine storm, IL-6 is a very good predictor of disease severity and prognosis, and its expression time is longer than other cytokines ([tumor necrosis factor] and IL-1). In addition, a significant rise in serum ferritin indicates the activation of the monocyte-macrophage system, which is a crucial part of inflammatory storm. These results indicate that patients with diabetes are susceptible to form an inflammatory storm, which eventually lead to rapid deterioration of COVID-19,” the authors wrote.

They also cited previous findings suggesting that coronavirus might exacerbate, or even cause, diabetes by seriously damaging islets (Acta Diabetol. 2010;47[3]:193-9). “Since viral infection may cause sharp fluctuation of the blood glucose levels of diabetes patients, which adversely affect the recovery of patients, there is reason to suspect that diabetes combined with SARS-CoV-2 pneumonia may form a vicious circle,” they wrote.

That’s one more reason to carefully monitor diabetes patients, said Dr. Rettinger. “Those patients who are able to make insulin might not be able to do so with the infection, and that may last a while, and they may require insulin. You want to keep a watch on things, and if oral agents are not working well, you want to go to insulin as quickly as you can. Probably diabetics should be way more careful and maybe visit the emergency department at earlier than a nondiabetic would.”

Dr. Raghu Mirmira

Raghavendra Mirmira, MD, PhD, who conducts translational research on diabetes and insulin production, said that the finding was not a complete surprise to him. “With a lot of diseases, having diabetes as a comorbidity can mean worse outcomes, and that’s certainly true of influenza. It was true for the other COVID-like illnesses, such as SARS and MERS,” Dr. Mirmira, who was not involved in the research, said in an interview.

If the findings hold up in larger numbers of patients and across multiple centers, they have the potential to inform patient management, said Dr. Mirmira, director of the Translational Research Center in the department of medicine at the University of Chicago. That will be especially true as data from long-term follow-up of become available. Elevated values in some biomarkers might dictate a patient be sent straight to the ICU or dictate admission to the hospital rather than being sent home, or it could assist patient selection for some of the new therapies that physicians hope will become available.

“The more information we get [about] total outcome, the more informed we’d be about who would benefit from some of the therapies that are in clinical trials now,” he said. Still, it will be a challenge to prove causation, because patients with diabetes have unique clinical characteristics that could also be the source of the difference.

Dr. Mirmira noted that patients with diabetes only were 20 years older on average than those with no comorbidities. “It’s really hard to know if what you’re looking at for the worse outcomes for people with diabetes is because they were older, and we know that older people tend to do much worse with COVID than younger people.” Ideally, patients would also be matched by age, but there are not enough data to do that yet.

The study was funded by the China National Natural Science Foundation. The authors reported no conflicts of interest. Dr. Rettinger has no relevant financial disclosures. Dr. Mirmira is on scientific advisory boards for Veralox Therapeutics, Sigilon Therapeutics, the Indiana Biosciences Research Institute, and the Juvenile Diabetes Research Foundation.

COVID-19 infection in patients with type 2 diabetes is associated with a greater increase in inflammatory and coagulation markers, compared with COVID-19 patients without diabetes, according to preliminary findings from a retrospective analysis of COVID-19 patients in Wuhan, China.

The results, though preliminary, could help explain why patients with diabetes and COVID-19 are at greater risk for more severe disease and death.

The results also suggest that more severe disease in patients with diabetes may be the result of a cytokine storm, in which the patient’s immune system overreacts to the virus and inflicts collateral damage on its own organs, according to Herbert I. Rettinger, MD, a clinical endocrinologist in Orange County, Calif., and member of the editorial advisory board for Clinical Endocrinology News. “Understanding the mechanism might help us understand the best way to treat,” COVID-19 in patients with diabetes, he said in an interview.

Dr. Rettinger, who was not involved in the research, noted that the study included only 24 patients with diabetes. Nevertheless, the finding of heightened inflammatory and coagulation markers was “fascinating.”

“This is the first paper I’ve seen [suggesting] that. I don’t know if we can extrapolate [the findings] to other populations, but if biomarkers are elevated in patients with COVID-19 and diabetes, then it’s something worth looking into, and to be aware of and cautious of. We need to pay attention to this,” he commented.

The study was led by Weina Guo and Desheng Hu at Huazhong University of Science and Technology in Wuhan, China, and published in Diabetes/Metabolism Research and Reviews.

The sample included 174 patients with COVID-19, who were treated consecutively during Feb. 10-29, 2020, at a single center. The researchers first assigned the patients to one of two groups – those with comorbid diabetes and those without. They further excluded all other comorbidities, focusing only on 26 patients with no comorbidities and 24 with only diabetes as a comorbidity, to remove all other comorbidities as possible confounding factors. Patients in the diabetes group were significantly older than those without diabetes (61 vs. 41 years, P < .01). The mortality rate was 16.5% in patients with diabetes and 0% in those without (P = .03).

COVID-19 patients with diabetes alone as a comorbidity had a greater risk for severe pneumonia, as evidenced by a higher mean CT score, compared with those without diabetes and no other comorbidities (P = .04). Patients with diabetes also had higher measures of release of tissue injury–related enzymes and were at higher risk of uncontrolled inflammation and hypercoagulable state. In particular, they had higher levels of interleukin-6 (13.7 vs. 4.1 pg/mL, respectively; P < .01), C-reactive protein (76.4 vs. 7.43 mg/L; P < .01), serum ferritin (764.8 vs. 128.9 ng/mL; P < .01), and D-dimer (1.16 vs. 0.25 mcg/mL; P < .01).

“It’s noteworthy that, for diseases that can induce a cytokine storm, IL-6 is a very good predictor of disease severity and prognosis, and its expression time is longer than other cytokines ([tumor necrosis factor] and IL-1). In addition, a significant rise in serum ferritin indicates the activation of the monocyte-macrophage system, which is a crucial part of inflammatory storm. These results indicate that patients with diabetes are susceptible to form an inflammatory storm, which eventually lead to rapid deterioration of COVID-19,” the authors wrote.

Drone flight launches first-ever insulin drop

Article Type
Changed
Tue, 05/03/2022 - 15:10

 

After a year of planning, researchers sent a drone flight off the coast of western Ireland to the Aran Islands, delivering insulin and glucagon and retrieving a blood sample from the first patient to receive insulin successfully by autonomous drone delivery.

The nuts and bolts of arranging the drop and retrieval, which occurred in September 2019, were detailed by Spyridoula Maraka, MD, during a virtual news conference held by the Endocrine Society. The study had been slated for presentaion during ENDO 2020, the society's annual meeting, which was canceled because of the COVID-19 pandemic.

“There are multiple medical drone delivery opportunities that could be lifesaving during sentinel events such as hurricanes, earthquakes, and, of course, pandemics like the one we are currently experiencing,” said Dr. Maraka. “Medications and blood samples are ideal [drone] payload cargo because of their low weight and high value.”

Drones, or unmanned aerial vehicles, are popular for recreational use and in some commercial applications – notably photography – but they are largely untapped as a medical resource, said Dr. Maraka, a collaborator on the project and an endocrinologist at the University of Arkansas for Medical Sciences, Little Rock.

Most of the exploration of drones for medical purposes has been in countries with emerging economies, such as Ghana and Rwanda in Africa, where the unmanned vehicles have been used by the U.S. medical product delivery company Zipline since 2016 to deliver blood.

The autonomous drone delivery of insulin originated in Galway, where the project’s lead investigator, Derek O’Keefe, MD, PhD, is an endocrinologist and professor of medical device technology at the National University of Ireland.

In 2017, Ireland was pummeled by Ophelia, a category 3 hurricane, and a year later by Storm Emma, a winter blizzard, said Dr. Maraka. Those extreme weather events trapped patients in their homes, made streets impassable for days on end, and interrupted the delivery of essential medical supplies, including insulin.

Until then, Ireland’s medical management plan had been passive and rested on the assumption that any weather-related interruptions would be relatively brief and not result in large-scale disruption of care and supply delivery for geographically isolated patients, said Dr. Maraka. But the two extreme and disruptive weather events in relatively quick succession prompted a reassessment of emergency medical management plans.

“We realized that [the prevailing plans were] not good enough,” said Dr. Maraka. “Medicine has a track record of practicing for emergencies before they actually happen,” to make sure that necessary resources are available and protocols in place in case of an emergency. The researchers extrapolated this preparedness mindset to medication delivery and realized that drones could be used both for a medication drop and to bring blood or other samples back from patients for testing.

Ireland’s Aran Islands came to mind as a location that was at risk of being cut off from services, but that was reachable by drone from Galway. “We quickly realized that this project would be very challenging, as no one in the developed world had done drone deliveries beyond the visual line of sight,” said Dr. Maraka, adding that flight operations had significant regulatory constraints.

The cross-disciplinary team that was pulled together to run the Diabetes Drone Mission, as the project was dubbed, included physicians and experts from pharmacies and pharmaceutical companies. To address drone operation specifically, a drone manufacturer, a flight operations firm, and a telecommunications company were also engaged. Drone pilots had to be licensed for beyond-the-visual-line-of-sight (BVLOS) operation, and Irish and European aviation regulators were consulted.

It took a full year to pull the pieces together for the inaugural flight. “One of the first challenges we faced was that we wanted to perform a civilian drone flight covering more than 40 kilometers,” said Dr. Maraka, whereas most drones flights are in the range of 1-10 km (0.6-6.2 miles). This long-range BVLOS flight required the drone to send live camera feed for the flight duration, which necessitated uninterrupted 4G wireless connectivity with satellite telecommunications as backup.

The Wingcopter 178 drone that was eventually chosen has a wingspan of 178 cm (about 70 inches) and can reach a top speed of 130 km/hr (about 81 mph) in fixed-wing mode.

“We had to comply with medication-dispensing legislation ... and we had to comply with medication transportation cold-chain legislation,” said Dr. Maraka. In other words, the insulin could not be loaded and delivered without the usual prescribing, dispensing, and chain-of-custody procedures being met.

In the end, the successful proof-of-concept flight saw the drone covering 43.3 km (26.9 miles) in a 32-minute flight to deliver insulin and glucagon and return a blood sample for hemoglobin A1c testing.

Dr. Maraka said she and her collaborators have an active collaboration with United Parcel Service and drone suppliers to expand into regular medical supply deliveries.

Dr. Maraka reported no conflicts of interest.

The report will be published in a special supplemental issue of the Journal of the Endocrine Society. In addition to a series of news conferences on March 30-31, the society will host ENDO Online 2020 during June 8-22, which will present programming for clinicians and researchers.

Use of diabetes technology is lower among black, Hispanic patients

Article Type
Changed
Tue, 05/03/2022 - 15:10

A retrospective study of patients at a minority-serving, safety-net hospital showed low uptake of diabetes technology among black patients with type 1 diabetes, compared with their white counterparts.

Dr. Kamonkiat Wirunsawanya

The researchers also found lower usage of the technology among Hispanic patients, but the difference, compared with their white counterparts, was not statistically significant after adjustments for language, insurance, age, and income. Patients who identified as “other” also were less likely than white patients to use the technology, which included continuous glucose monitors and continuous subcutaneous insulin infusion devices.

The data differes from other, similar studies of technology use in patients with type 1 diabetes, because the study population, drawn from the Boston University Medical Center, was more diverse than other studies, according to Kamonkiat Wirunsawanya, who is an endocrinology fellow at the medical center. The abstract had been slated for presentation at ENDO 2020, the Endocrine Society's annual meeting, which was canceled because of the COVID-19 pandemic.

Dr. Wirunsawanya and his colleagues are now using questionnaires to try to identify specific patient and physician factors that might explain the differences in technology use.

“Once we know which factors could be a barrier to using the technology, we’ll be able to implement a strategy to increase use in those patients,” Dr. Wirunsawanya said in an interview. The issue could be a two-way street, he noted, because some providers may be uncomfortable using the technology, or may perceive minorities as less adept at using technology.

The study included 227 adult patients who were seen at the medical center between October 2016 and September 2017. The mean age was 39 years, and 59% were men. The mean duration of type 1 diabetes was 21 years, and 30% of the patients were overweight, 22% were obese, 80% spoke English, and 50% were on government insurance. In all, 43% of the patients were white, 25% were black, 15% were Hispanic, 2% were Asian, and 15% identified as other.

Patients who used technology had lower mean levels of hemoglobin A1c, compared with nonusers (8.27% vs. 9.49%, respectively). Those with government health insurance were less likely than those with private insurance to use technology (odds ratio, 0.43; 95% confidential interval, 0.25-0.74).

Overall, 26% of the patients used continuous subcutaneous insulin infusion devices. Of those, 43% were white, 10% black, 14% Hispanic, none were Asian, and 18% identified as other.

In addition, 30% of the patients used continuous glucose monitors; of those, 47% were white, 14% black, 23% Hispanic, 25% Asian, and none identified as other.

After adjustments for insurance and language, the researchers found that black patients were less likely to use technology than were the white patients (OR, 0.25; 95% CI, 0.11-0.53). The same was found for those who identified as other (OR, 0.33; 95% CI, 0.12-0.89). There was no significant differences in technology use between white and Asian patients. After adjustments, the researchers showed that fewer Hispanic patients used technology, compared with their white counterparts, but the difference was not statistically significant.

In a multivariable logistic regression model that adjusted for insurance and language, black patients had lower odds of using technology, compared with white patients (OR, 0.25; 95% CI, 0.11-0.53), as did those identifying as other (OR, 0.33; 95% CI, 0.12-0.89).

Dr. Anne Peters

In an interview, Anne Peters, MD, director of clinical diabetes programs at the University of Southern California, Los Angeles, said that the study highlights a common problem with introducing technology to underserved populations. “These study [findings are] not at all surprising. It’s something that is a puzzle for those of us who work in the field of diabetes management in patients from underserved communities. Even if you can get access to the technology, even when I get them tools and native Spanish-speaking educators and people who should be able to teach them how to use the technology, the adoption of the technology has been really much less than would be expected,” said Dr. Peters, who is also a professor of medicine at USC and was not involved in the research.

Part of the problem may be lack of contact with health care services, she said. White children with type 1 diabetes are treated from an early age and learn how to manage daily blood sugar levels. They often grow up to embrace technology, even enthusiastically. But in some minority communities, diabetes is viewed as something to be hidden away. That cultural difference is also a frustrating barrier.

“What happens in more affluent groups is that people learn from their peers, and they see that [managing their blood sugar] is possible. One of my big beliefs is that the answer has to come from [the community]. ... We need to get champions, people from the community who use these tools, to encourage others, and that’s hard to do because type 1 diabetes is such a small subset of the people with diabetes who are [black] or Latino,” said Dr. Peters.

Ultimately, the solution will require a shift in messaging by finding a way to help communities look differently at diabetes and its treatment. “There’s something that must come educationally and culturally that I’ve not figured out [yet]. I can get resources and fight for them, but we have to figure out how to make [technology] part of that culture, and I don’t know that we’ve done that,” she said.

Dr. Wirunsawanya reported no financial conflicts of interest. Dr. Peters has been on an advisory panel for Abbott Diabetes Care and has received research funding from Dexcom.

Dr. Wirunsawanya and colleagues’ research will be published in a special supplemental issue of the Journal of the Endocrine Society. In addition to a series of news conferences on March 30-31, the society will host ENDO Online 2020 during June 8-22, which will present programming for clinicians and researchers.

A retrospective study of patients at a minority-serving, safety-net hospital showed low uptake of diabetes technology among black patients with type 1 diabetes, compared with their white counterparts.

Dr. Kamonkiat Wirunsawanya

The researchers also found lower usage of the technology among Hispanic patients, but the difference, compared with their white counterparts, was not statistically significant after adjustments for language, insurance, age, and income. Patients who identified as “other” also were less likely than white patients to use the technology, which included continuous glucose monitors and continuous subcutaneous insulin infusion devices.

The data differes from other, similar studies of technology use in patients with type 1 diabetes, because the study population, drawn from the Boston University Medical Center, was more diverse than other studies, according to Kamonkiat Wirunsawanya, who is an endocrinology fellow at the medical center. The abstract had been slated for presentation at ENDO 2020, the Endocrine Society's annual meeting, which was canceled because of the COVID-19 pandemic.

Dr. Wirunsawanya and his colleagues are now using questionnaires to try to identify specific patient and physician factors that might explain the differences in technology use.

“Once we know which factors could be a barrier to using the technology, we’ll be able to implement a strategy to increase use in those patients,” Dr. Wirunsawanya said in an interview. The issue could be a two-way street, he noted, because some providers may be uncomfortable using the technology, or may perceive minorities as less adept at using technology.
