Despite a lack of financial penalties, the U.S. Veterans Affairs Health Care System has seen a steady 15% reduction in 30-day all-cause readmissions for patients admitted for heart failure, with no concurrent increase in 30-day mortality, a large cohort study suggests.

Unlike the Center for Medicare & Medicaid’s Hospital Readmissions Reduction Program (HRRP), whose primary objective is reducing payments to hospitals with excess readmissions, the VA’s efforts to reduce readmissions across their system did not include any financial penalties.

“The intervention focused on encouraging participation in transitions of care programs, such as the American College of Cardiology’s Hospital to Home Initiative and the creation of a heart failure provider network that included more than 900 heart failure providers throughout the VA system,” said the study’s lead author Justin T. Parizo, MD, of Stanford (Calif.) University.

The only measuring sticks the VA used were the public reporting of 30-day readmission rates (starting in 2012) and inclusion of those rates into hospitals’ overall star ratings (starting in 2014).  

“The readmissions reductions we saw were similar in magnitude to those seen in patients in CMS fee-for-service categories in the HRRP,” said Dr. Parizo. “And while we had no ability to evaluate causality here, our best guess from what we can see is that there’s been no impact of the readmissions program on mortality,” he added.

Their results were published online June 17 in JAMA Cardiology.

Dr. Parizo and colleagues conducted a cohort study of 304,374 heart failure hospital admissions in 164,566 patients from January 2007 to September 2017. Importantly, he stressed, the researchers were able to do sophisticated risk adjustment for illness trends, something that has been a sticking point in some of the HRRP studies to date.

“We leveraged the robust dataset that the VA provides to adjust for illness severity. Accounting for clinical factors, like blood pressure, weight, creatinine, BNP [B-type natriuretic peptide], and other markers of heart failure severity, but also for changes in coding,” said Dr. Parizo.

Stratification according to left ventricular ejection fraction (LVEF) showed similar results both in terms of 30-day readmission and 30-day mortality for those with LVEF of 40% or greater and those with LVEF less than 40%.

In an interview, Dr. Parizo noted that they actually saw a small but significant uptick in mortality in the 2011-2012 period (compared with 2007-2008) that remains unexplained. “By the 2015-2017 period, 30-day death had returned to baseline levels,” he said.

In contrast, the HRRP, which was rolled out in 2012, has also been shown to reduce readmissions but, in most studies, 30-day mortality had gone up.

“The VA has a very robust quality infrastructure and a robust mechanism for prioritizing certain quality-improvement goals and getting them accomplished that I think they are underrecognized for,” said Leora Horwitz, MD, MHS, the director of the Center for Healthcare Innovation and Delivery Science at NYU Langone Medical Center, New York.

In an interview, she also noted some concern with the uptick seen in the 2011-2012 period, noting that the increase might be the same signal seen with the HRRP intervention.

“This is around the same time period where other people were writing the HRRP papers that showed an increase in mortality, so that’s something to consider,” she said.

Dr. Horwitz coauthored a study published in 2017 indicating that, on a hospital level (compared with a patient level, the approach most other studies took), reductions in readmissions were only weakly correlated with 30-day mortality rates after discharge.

“So, if you think that a hospital that’s behaving badly and keeping people out of the hospital inappropriately to cut down their readmissions, you’d expect to see increased mortality in that hospital, and in our study there was no correlation whatsoever. So there is still debate as to what is behind the increase in mortality on a patient level with heart failure that we’ve seen in some studies,” she said.

Dr. Horwitz doubts an intervention such as the one undertaken in the VA system – even with its fairly soft-touch “name and shame” component – would work in the non-VA hospital world.

“Those who have been in favor of financial penalties have pointed to the fact that, in general, it’s hard to get health systems to respond without financial alignment, even if it’s not an overt financial incentive,” she said.

“The VA is a unique environment,” she noted. “They have a very strong top-down command control focus where people are kind of used to being told, ‘OK, here are the measures we have to address this year.’ It’s good to see that the system that has worked for them for other outcomes also worked for them for heart failure readmissions too.”

Dr. Parizo has disclosed no relevant financial relationships. Dr. Horwitz has worked under contract to Medicare to develop readmission measures.

Patients with COVID-19 who have high levels of the steroid hormone cortisol on admission to hospital have a substantially increased risk of dying, U.K. researchers have discovered.

Waljit S. Dhillo, MBBS, PhD, head of the division of diabetes, endocrinology and metabolism at Imperial College London, and colleagues studied 535 patients admitted to major London hospitals. Their article was published online June 18 in Lancet Diabetes & Endocrinology.

“Our analyses show for the first time that patients with COVID-19 mount a marked and appropriate acute cortisol stress response,” said Dr. Dhillo and colleagues.

Moreover, “high cortisol concentrations were associated with increased mortality and a reduced median survival, probably because this is a marker of the severity of illness.”

So measuring cortisol on admission is potentially “another simple marker to use alongside oxygen saturation levels to help us identify which patients need to be admitted immediately, and which may not,” Dr. Dhillo noted in a statement from his institution.

“Having an early indicator of which patients may deteriorate more quickly will help us with providing the best level of care as quickly as possible. In addition, we can also take cortisol levels into account when we are working out how best to treat our patients,” he said.

However, it’s important to note that this means – particularly in the wake of the RECOVERY trial reported last week – that “in the early part of the disease you don’t need steroids,” he said.
 

In contrast to SARS, no adrenal insufficiency with COVID-19

Cortisol levels when healthy and resting are 100-200 nmol/L and nearly zero when sleeping, the researchers explained.

They decided to examine cortisol levels because, although physiological stress from critical illness normally increases levels of the hormone, the prior coronavirus, severe acute respiratory syndrome coronavirus (SARS-CoV), had the opposite effect and induced cortisol insufficiency in some patients.

“We would have said we’re not quite sure” what effect SARS-CoV-2 is having on cortisol levels, “so that’s why we collected the data,” Dr. Dhillo said in an interview.

The researchers studied patients admitted to three large London teaching hospitals between March 9 and April 22 with a clinical suspicion of SARS-CoV-2 infection. All patients had a standard set of blood tests, including full blood count, creatinine, C-reactive protein, D-dimer, and serum cortisol.

After exclusions, the team assessed 535 patients admitted over the study period who had baseline cortisol measured within 48 hours of admission.

Of these, 403 patients were diagnosed with COVID-19 based on a positive result on real-time polymerase chain reaction testing (88%) or a strong clinical and radiological suspicion, despite a negative test (12%).

In total, 132 (25%) individuals were not diagnosed with COVID-19.

Patients with COVID-19 were a mean age of 66.3 years, and 59.6% were men.

Mean cortisol concentrations in patients with COVID-19 were significantly higher than those not diagnosed with the virus (619 vs 519 nmol/L; P < .0001).

And by May 8, significantly more patients with COVID-19 died than those without (27.8% vs 6.8%; P < .0001).

Doubling of cortisol levels associated with 40% higher mortality

Multivariate analysis taking into account age, presence of comorbidities, and laboratory tests revealed that a doubling of cortisol concentrations among those with COVID-19 was associated with a significant increase in mortality, at a hazard ratio of 1.42 (P = .014).

And patients with COVID-19 whose baseline cortisol level was >744 nmol/L had a median survival of just 15 days, compared with those with a level ≤744 nmol/L, who had a median survival of 36 days (P < .0001).

The team notes that the cortisol stress responses in their patients with COVID-19 ranged up to 3,241 nmol/L, which is “a marked cortisol stress response, perhaps higher than is observed in patients undergoing major surgery.”

Of interest, there was no interaction between cortisol levels and ethnicity in their study; a subsequent analysis of the data stratified by black, Asian, and other minority ethnicities revealed no significant differences.

The team note that their results will need to be reproduced in other populations.

“Any potential role for cortisol measurement at baseline and later during an inpatient stay with COVID-19 as a prognostic biomarker, either by itself or in combination with other biomarkers, will require validation in a prospective study.”
 

Implications for treatment: Reserve dexamethasone for critically ill

Dr. Dhillo explained that, because their findings indicate that people initially infected with COVID-19 do mount an appropriate stress (cortisol) response, it is important that people properly understand this in the wake of the RECOVERY trial, reported last week.

The trial showed that the widely available steroid dexamethasone significantly reduced mortality among severely ill COVID-19 patients in the intensive care unit when given at a supraphysiologic dose of 6 mg.

But it would be hazardous for anyone to self-medicate with steroids at an early stage of COVID-19 because that would further increase cortisol levels and could suppress the immune system.

“For the average person on the street with COVID-19,” excess steroids will make their symptoms worse, Dr. Dhillo explained, adding this is important to emphasize because dexamethasone, and similar steroids, “are cheap and likely available on the Internet, and so misunderstanding of the RECOVERY trial could have serious implications.”

But once patients are very sick, with “inflammation in their lungs” and are in the intensive care unit, and often on ventilators – which is a very small subgroup of those with COVID-19 – it becomes a very different story, he stressed.

“RECOVERY shows clearly there seems to be a benefit once you need oxygen or are on a ventilator, and that makes sense because [dexamethasone] is going to be an anti-inflammatory,” in this instance when the “lungs are full of water.”

“But in the early days you definitely don’t need it and it could be harmful,” he reiterated.

The study is funded by the U.K. National Institute for Health Research and Medical Research Council. The authors have reported no relevant financial relationships.

It’s bad news for patients with newly diagnosed type 2 diabetes when they then develop heart failure during the next few years.

Patients with incident type 2 diabetes (T2D) who soon after also had heart failure appear faced a dramatically elevated mortality risk, higher than the incremental risk from any other cardiovascular or renal comorbidity that appeared following diabetes onset, in an analysis of more than 150,000 Danish patients with incident type 2 diabetes during 1998-2015.

The 5-year risk of death in patients who developed heart failure during the first 5 years following an initial diagnosis of T2D was about 48%, about threefold higher than in patients with newly diagnosed T2D who remained free of heart failure or any of the other studied comorbidities, Bochra Zareini, MD, and associates reported in a study published in Circulation: Cardiovascular Quality and Outcomes. The studied patients had no known cardiovascular or renal disease at the time of their first T2D diagnosis.

“Our study reports not only on the absolute 5-year risk” of mortality, “but also takes into consideration when patients developed” a comorbidity. “What is surprising and worrying is the very high risk of death following heart failure and the potential life years lost when compared to T2D patients who do not develop heart failure,” said Dr. Zareini, a cardiologist at Herlev and Gentofte University Hospital in Copenhagen. “The implications of our study are to create awareness and highlight the importance of early detection of heart failure development in patients with T2D.” The results also showed that “heart failure is a common cardiovascular disease” in patients with newly diagnosed T2D, she added in an interview.

The data she and her associates reported came from a retrospective analysis of 153,403 Danish citizens in national health records who received a prescription for an antidiabetes drug for the first time during 1998-2015, excluding patients with a prior diagnosis of heart failure, ischemic heart disease (IHD), stroke, peripheral artery disease (PAD), chronic kidney disease (CKD), or gestational diabetes. They followed these patients for a median of just under 10 years, during which time 45% of the cohort had an incident diagnosis of at least one of these cardiovascular and renal conditions, based on medical-record entries from hospitalization discharges or ambulatory contacts.

Nearly two-thirds of the T2D patients with an incident comorbidity during follow-up had a single new diagnosis, a quarter had two new comorbidities appear during follow-up, and 13% developed at least three new comorbidities.
 

Heart failure, least common but deadliest comorbidity

The most common of the tracked comorbidities was IHD, which appeared in 8% of the T2D patients within 5 years and in 13% after 10 years. Next most common was stroke, affecting 3% of patients after 5 years and 5% after 10 years. CKD occurred in 2.2% after 5 years and in 4.0% after 10 years, PAD occurred in 2.1% after 5 years and in 3.0% at 10 years, and heart failure occurred in 1.6% at 5 years and in 2.2% after 10 years.

But despite being the least common of the studied comorbidities, heart failure was by far the most deadly, roughly tripling the 5-year mortality rate, compared with T2D patients with no comorbidities, regardless of exactly when it first appeared during the first 5 years after the initial T2D diagnosis. The next most deadly comorbidities were stroke and PAD, which each roughly doubled mortality, compared with the patients who remained free of any studied comorbidity. CKD boosted mortality by 70%-110%, depending on exactly when it appeared during the first 5 years of follow-up, and IHD, while the most frequent comorbidity was also the most benign, increasing mortality by about 30%.

The most deadly combinations of two comorbidities were when heart failure appeared with either CKD or with PAD; each of these combinations boosted mortality by 300%-400% when it occurred during the first few years after a T2D diagnosis.

The findings came from “a very big and unselected patient group of patients, making our results highly generalizable in terms of assessing the prognostic consequences of heart failure,” Dr. Zareini stressed.
 

Management implications

The dangerous combination of T2D and heart failure has been documented for several years, and prompted a focused statement in 2019 about best practices for managing these patients (Circulation. 2019 Aug 3;140[7]:e294-324). “Heart failure has been known for some time to predict poorer outcomes in patients with T2D. Not much surprising” in the new findings reported by Dr. Zareini and associates, commented Robert H. Eckel, MD, a cardiovascular endocrinologist at the University of Colorado at Denver, Aurora. Heart failure “rarely acts alone, but in combination with other forms of heart or renal disease,” he noted in an interview.

Earlier studies may have “overlooked” heart failure’s importance compared with other comorbidities because they often “only investigated one cardiovascular disease in patients with T2D,” Dr. Zareini noted. In recent years the importance of heart failure occurring in patients with T2D also gained heightened significance because of the growing role of the sodium-glucose cotransporter 2 (SGLT2) inhibitor drug class in treating patients with T2D and the documented ability of these drugs to significantly reduce hospitalizations for heart failure (J Am Coll Cardiol. 2020 Apr 28;75[16]:1956-74). Dr. Zareini and associates put it this way in their report: “Heart failure has in recent years been recognized as an important clinical endpoint ... in patients with T2D, in particular, after the results from randomized, controlled trials of SGLT2 inhibitors showed benefit on cardiovascular death and heart failure hospitalizations.”

Despite this, the new findings “do not address treatment with SGLT2 inhibitors in patients with T2D, nor can we use our data to address which patients should not be treated,” with this drug class, which instead should rely on “current evidence and expert consensus,” she said.

“Guidelines favor SGLT2 inhibitors or [glucagonlike peptide–1] receptor agonists in patients with a history of or high risk for major adverse coronary events,” and SGLT2 inhibitors are also “preferable in patients with renal disease,” Dr. Eckel noted.

Other avenues also exist for minimizing the onset of heart failure and other cardiovascular diseases in patients with T2D, Dr. Zareini said, citing modifiable risks that lead to heart failure that include hypertension, “diabetic cardiomyopathy,” and ISD. “Clinicians must treat all modifiable risk factors in patients with T2D in order to improve prognosis and limit development of cardiovascular and renal disease.”

The study received no commercial funding. Dr. Zareini and Dr. Eckel had no disclosures.

It’s bad news for patients with newly diagnosed type 2 diabetes when they then develop heart failure during the next few years.

Patients with incident type 2 diabetes (T2D) who soon after also had heart failure appear faced a dramatically elevated mortality risk, higher than the incremental risk from any other cardiovascular or renal comorbidity that appeared following diabetes onset, in an analysis of more than 150,000 Danish patients with incident type 2 diabetes during 1998-2015.

The 5-year risk of death in patients who developed heart failure during the first 5 years following an initial diagnosis of T2D was about 48%, about threefold higher than in patients with newly diagnosed T2D who remained free of heart failure or any of the other studied comorbidities, Bochra Zareini, MD, and associates reported in a study published in Circulation: Cardiovascular Quality and Outcomes.

A new article in the Journal of Clinical Endocrinology & Metabolism (JCEM) addresses unique concerns and considerations regarding diabetic ketoacidosis (DKA) in the setting of COVID-19.

Corresponding author Marie E. McDonnell, MD, director of the diabetes program at Brigham and Women’s Hospital, Boston, Massachusetts, discussed the recommendations with Medscape Medical News and also spoke about the news this week that the corticosteroid dexamethasone reduced death rates in severely ill patients with COVID-19.

The full JCEM article, by lead author Nadine E. Palermo, DO, Division of Endocrinology, Diabetes, and Hypertension, also at Brigham and Women’s Hospital, covers DKA diagnosis and triage, and emphasizes that usual hospital protocols for DKA management may need to be adjusted during COVID-19 to help preserve personal protective equipment and ICU beds.

“Hospitals and clinicians need to be able to quickly identify and manage DKA in COVID patients to save lives. This involves determining the options for management, including when less intensive subcutaneous insulin is indicated, and understanding how to guide patients on avoiding this serious complication,” McDonnell said in an Endocrine Society statement.
 

What about dexamethasone for severe COVID-19 in diabetes?

The new article briefly touches on the fact that upward adjustments to intensive intravenous insulin therapy for DKA may be necessary in patients with COVID-19 who are receiving concomitant corticosteroids or vasopressors.

But it was written prior to the June 16 announcement of the “RECOVERY” trial results with dexamethasone. The UK National Health Service immediately approved the drug’s use in the COVID-19 setting, despite the fact that there has been no published article on the findings yet.

McDonnell told Medscape Medical News that she would need to see formal results to better understand exactly which patients were studied and which ones benefited.

“The peer review will be critical. It looks as if it only benefits people who need respiratory support, but I want to understand that in much more detail,” she said. “If they all had acute respiratory distress syndrome [ARDS],” that’s different.

“There are already some data supporting steroid use in ARDS,” she noted, but added that not all of it suggests benefit.

She pointed to one of several studies now showing that diabetes, and hyperglycemia among people without a prior diabetes diagnosis, are both strong predictors of mortality in hospitalized patients with COVID-19.

“There was a very clear relationship between hyperglycemia and outcomes. We really shouldn’t put people at risk until we have clear data,” she said.

If, once the data are reviewed and appropriate dexamethasone becomes an established treatment for severe COVID-19, hyperglycemia would be a concern among all patients, not just those with previously diagnosed diabetes, she noted.

“We know a good number of people with prediabetes develop hyperglycemia when put on steroids. They can push people over the edge. We’re not going to miss anybody, but treating steroid-induced hyperglycemia is really hard,” McDonnell explained.

She also recommended 2014 guidance from Diabetes UK and the Association of British Clinical Diabetologists, which addresses management of inpatient steroid-induced DKA in patients with and without pre-existing diabetes.

Another major concern, she said, is “patients trying to get dexamethasone when they start to get sick” because this is not the right population to use this agent.

“We worry about people who do not need this drug. If they have diabetes, they put themselves at risk of hyperglycemia, which then increases the risk of severe COVID-19. And then they’re also putting themselves at risk of DKA. It would just be bad medicine,” she said.

Managing DKA in the face of COVID-19: Flexibility is key

In the JCEM article, Palermo and colleagues emphasize that the usual hospital protocols for DKA management may need to be adjusted during COVID-19 in the interest of reducing transmission risk and preserving scare resources.

They provide evidence for alternative treatment strategies, such as the use of subcutaneous rather than intravenous insulin when appropriate.

“We wanted to outline when exactly you should consider nonintensive management strategies for DKA,” McDonnell further explained to Medscape Medical News.

“That would include those with mild or some with moderate DKA. ... The idea is to remind our colleagues about that because hospitals tend to operate on a protocol-driven algorithmic methodology, they can forget to step off the usual care pathway even if evidence supports that,” she said.   

But on the other hand, she also said that, in some very complex or severely ill patients with COVID-19, classical intravenous insulin therapy makes the most sense even if their DKA is mild.
 

The outpatient setting: Prevention and preparation

The new article also addresses several concerns regarding DKA prevention in the outpatient setting.

As with other guidelines, it includes a reminder that patients with diabetes should be advised to discontinue sodium-glucose cotransporter 2 (SGLT2) inhibitors if they become ill with COVID-19, especially if they’re not eating or drinking normally, because they raise the risk for DKA.

Also, for patients with type 1 diabetes, particularly those with a history of repeated DKA, “this is the time to make sure we reach out to patients to refill their insulin prescriptions and address issues related to cost and other access difficulties,” McDonnell said.

The authors also emphasize that insulin starts and education should not be postponed during the pandemic. “Patients identified as meeting criteria to start insulin should be referred for urgent education, either in person or, whenever possible and practical, via video teleconferencing,” they urge.

McDonnell has reported receiving research funding from Novo Nordisk. The other two authors have reported no relevant financial relationships.

“That would include those with mild or some with moderate DKA. ... The idea is to remind our colleagues about that because hospitals tend to operate on a protocol-driven algorithmic methodology, they can forget to step off the usual care pathway even if evidence supports that,” she said.   

But on the other hand, she also said that, in some very complex or severely ill patients with COVID-19, classical intravenous insulin therapy makes the most sense even if their DKA is mild.
 

The outpatient setting: Prevention and preparation

The new article also addresses several concerns regarding DKA prevention in the outpatient setting.

As with other guidelines, it includes a reminder that patients with diabetes should be advised to discontinue sodium-glucose cotransporter 2 (SGLT2) inhibitors if they become ill with COVID-19, especially if they’re not eating or drinking normally, because they raise the risk for DKA.

Also, for patients with type 1 diabetes, particularly those with a history of repeated DKA, “this is the time to make sure we reach out to patients to refill their insulin prescriptions and address issues related to cost and other access difficulties,” McDonnell said.

The authors also emphasize that insulin starts and education should not be postponed during the pandemic. “Patients identified as meeting criteria to start insulin should be referred for urgent education, either in person or, whenever possible and practical, via video teleconferencing,” they urge.

McDonnell has reported receiving research funding from Novo Nordisk. The other two authors have reported no relevant financial relationships.

A phone, an app, and the next generation of implanted cardiac device data signaling produced an unprecedented level of data transmission compliance in a single-arm, multicenter, pilot study with 245 patients, adding momentum to the expanding penetration of personal smart devices into cardiac electrophysiology.

During 12-month follow-up, the 245 patients who received either a medically indicated pacemaker or cardiac resynchronization therapy (CRT)–pacemaker equipped with Bluetooth remote transmission capability had successful data transfer to their clinicians for 95% of their scheduled data uploads while using a personal phone or tablet as the link between their heart implant and the Internet. This rate significantly surpassed the transmission-success rates tallied by traditional, bedside transmitters in historical control groups, Khaldoun G. Tarakji, MD, said at the annual scientific sessions of the Heart Rhythm Society, held online because of COVID-19.

A related analysis by Dr. Tarakji and colleagues of 811 patients from real-world practice who received similar implanted cardiac devices with the same remote-transmission capability showed a 93% rate of successful data transfers via smart devices.

In contrast, historical performance showed a 77% success rate in matched patients drawn from a pool of more than 69,000 people in routine care who had received a pacemaker or CRT-pacemaker that automatically transmitted to a bedside monitor. Historical transmission success among matched patients from a pool of more than 128,000 routine-care patients with similar implants who used a wand to interrogate their implants before the attached monitor transmitted their data had a 56% rate of successful transmissions.

Cardiac device signals that flow directly into a patient’s phone or pad and then relay automatically via an app to the clinic “are clearly much easier,” than the methods now used, observed Dr. Tarakji, a cardiac electrophysiologist at the Cleveland Clinic. “It is truly as seamless as possible. Patients don’t really need to do anything,” he said during a press briefing. The key is that most patients tend to keep their smart devices, especially their phones, near them all the time, which minimizes the chance that the implanted cardiac device might try to file a report when the patient is not positioned near the device that’s facilitating transmission. When patients use conventional, bedside transmitters they can forget to bring them on trips, while many fewer fail to take their phone. Another advantage is that the link between a phone and a cardiac implant can be started in the clinic once the patient downloads an app. Bedside units need home setup, and “some patients never even get theirs out of the box,” Dr. Tarakji lamented.

Another feature of handheld device transmissions that run off an app is that the app can display clinical metrics, activity, device performance, and transmission history, as well as educational information. All of these features can enhance patient engagement with their implanted device, their arrhythmia, and their health status. Bedside units often give patients little feedback, and they don’t display clinical data. “The real challenge for clinicians is what data you let patients see. That’s complicated,” Dr. Tarakji said.

“This study was designed to see whether the technology works. The next step is to study how it affects risk-factor modification” or other outcomes. “There are many opportunities” to explore with this new data transmission and processing capability, he concluded.

The BlueSync Field Evaluation study enrolled patients at 20 centers in the United States, France, Italy, and the United Kingdom during 2018, and the 245 patients who received a BlueSync device and were included in the analysis sent at least one of their scheduled data transmissions during their 12 months of follow-up. Participants were eligible if they were willing to use their own smart phone or pad that could interact with their cardiac implant, and included both first-time implant recipients as well as some patients who received replacement units.

Personal device–based data transmission from cardiac implants “will no doubt change the way we manage patients,” commented Nassir F. Marrouche, MD, a cardiac electrophysiologist and professor of medicine at Tulane University in New Orleans, and a designated discussant for the report. “Every implanted cardiac device should be able to connect with a phone, which can improve adoption and adherence,” he said.

But the study has several limitations for interpreting the implications of the findings, starting with its limited size and single-arm design, noted a second discussant, Roderick Tung, MD, director of cardiac electrophysiology at the University of Chicago. Another issue is the generalizability of the findings, which are likely biased by involving only patients who own a smart phone or tablet and may be more likely to transmit their data regardless of the means. And comparing transmission success in a prospective study with rates that occurred during real-world, routine practice could have a Hawthorne effect bias, where people under study behave differently than they do in everyday life. But that effect may be mitigated by confirmatory findings from a real-world group that also used smart-device transmission included in the report. Despite these caveats, it’s valuable to develop new ways of improving data collection from cardiac devices, Dr. Tung said.

The BlueSync Field Evaluation study was sponsored by Medtronic, the company that markets Bluetooth-enabled cardiac devices. Dr. Tarakji has been a consultant to Medtronic, and also to AliveCor, Boston Scientific, and Johnson & Johnson. Dr. Marrouche has been a consultant to Medtronic as well as to Biosense Webster, Biotronik, Cardiac Design, and Preventice, and he has received research funding from Abbott, Biosense Webster, Boston Scientific, and GE Healthcare. Dr. Tung has been a speaker on behalf of Abbott, Boston Scientific, and Biosense Webster.

Optimizing glycemic control “is the key to overall treatment in people with diabetes and COVID-19,” said Antonio Ceriello, MD, during a June 5 webinar sponsored by Harvard Medical School, Boston.

Dr. Ceriello, a research consultant with the Italian Ministry of Health, IRCCS Multi-Medica, Milan, highlighted a recent study that examined the association of blood glucose control and outcomes in COVID-19 patients with preexisting type 2 diabetes.

Among 7,000 cases of COVID-19, type 2 diabetes correlated with a higher death rate. However, those with well-controlled blood glucose (upper limit ≤10 mmol/L) had a survival rate of 98.9%, compared with just 11% among those with poorly controlled blood glucose (upper limit >10 mmol/L), a reduction in risk of 86% (adjusted hazard ratio, 0.14; Cell Metab. 2020 May 1. doi: 10.1016/j.cmet.2020.04.021).

Clinicians should also consider the possible side effects of hypoglycemic agents in the evolution of this disease. This is true of all patients, not just diabetes patients, Dr. Ceriello said. “We have data showing that ... hyperglycemia contributes directly to worsening the prognosis of COVID-19 independent of the presence of diabetes.”

One study found that the glycosylation of ACE-2 played an important role in allowing cellular entry of the virus (Am J Physiol Endocrinol Metab. 2020 Mar 31;318:E736-41). “This is something that could be related to hyperglycemia,” he added.

Another risk factor is thrombosis, a clear contributor to death rates in COVID-19. Research on thrombosis incidence in COVID-19 patients with diabetes reported higher levels of D-dimer levels in people with diabetes, especially among those who couldn’t manage their disease.

Tying all of these factors together, Dr. Ceriello discussed how ACE-2 glycosylation, in combination with other factors in SARS-CoV-2 infection, could lead to hyperglycemia, thrombosis, and subsequently multiorgan damage in diabetes patients.

Other research has associated higher HbA1c levels (mean HbA1c, 7.5%) with higher mortality risk in COVID-19 patients, said another speaker, Linong Ji, MD, director for endocrinology and metabolism at Peking University People’s Hospital, Beijing, and director of Peking University’s Diabetes Center. Proper guidance is key to ensuring early detection of hyperglycemic crisis in people with diabetes, advised Dr. Ji.

Global management of diabetes in SARS-CoV-2 patients is “quite challenging,” given that most patients don’t have their diabetes under control, said host and moderator A. Enrique Caballero, MD, an endocrinologist/investigator in the division of endocrinology, diabetes, and hypertension and division of global health equity at Brigham and Women’s Hospital, Boston. “They are not meeting treatment targets for cholesterol or glucose control. So we’re not managing optimal care. And now on top of this, we have COVID-19.”

The Abbott FreeStyle Libre glucose monitoring system significantly reduced hospitalizations for diabetic ketoacidosis (DKA), diabetes-related emergencies, and all-cause hospitalizations among patients with diabetes, data from two new studies indicate.

The results were presented June 13 during the virtual American Diabetes Association (ADA) 80th Scientific Sessions.

One large database analysis, from France, revealed that use of the Libre system halved hospitalization rates for DKA among people with type 1 or type 2 diabetes.

In the other study, a retrospective analysis of data from over 1200 insulin-treated individuals with type 2 diabetes in the United States, use of the Libre was associated with significant reductions in both hospitalizations for acute diabetes-related emergency events and all-cause hospitalizations.

The Libre system reads glucose levels through a sensor worn on the back of the upper arm for up to 14 days. Users wave a scanner over the device to obtain a reading.

Asked to comment, Nicholas Argento, MD, diabetes technology director at Maryland Endocrine and Diabetes, Columbia, told Medscape Medical News: “One of the biggest problems with access to continuous glucose monitoring is cost. Payers need to see that there’s some cost-saving to offset the cost of paying for these devices. I think both of these studies are important for that reason.”

However, Argento also said he recommends that people with type 1 diabetes use the Dexcom continuous glucose monitor (CGM) if possible rather than the Libre, despite the former’s higher cost, because it has an alarm feature that the Libre doesn’t and is more accurate in the hypoglycemic range.

Large French study: Libre cuts DKA hospitalizations by 50%

The FreeStyle Libre system has been reimbursed in France since June 1, 2017 for patients over 4 years of age with type 1 or type 2 diabetes who take at least 3 insulin injections per day or use an insulin pump.

Sara Freeman/MDedge News

The new results were presented by Ronan Roussel, MD, PhD, chief of the endocrinology, diabetes, and nutrition department at Hôpital Bichat, Fédération de Diabétologie, AP-HP, Paris, France.

The DKA hospitalization data Roussel reported were part of a larger longitudinal retrospective cohort study looking at overall prescribing and use of the Libre system, and its impact on healthcare outcomes and associated costs in standard practice in France. The data came from a large nationwide claims database containing all healthcare expenses for over 66 million people.

The current study participants were 74,076 individuals with at least a full year of follow-up beginning in 2017 with the date of first reimbursement for the FreeStyle Libre system. Of those, 44.8% (33,203) had type 1 diabetes and 55.2% (40,955) had type 2 diabetes.

Prior to initiation of Libre use, about a quarter of each group was using 0 fingerstick test strips per day, about 19% of the type 1 diabetes group and 28% of the type 2 diabetes group were using 1-3 strips per day, and about half of both groups were using 4 or more strips per day.

Compared with the year prior to the date of first reimbursement for the Libre, hospitalization rates for DKA during the first year of Libre use fell by 52% in the type 1 diabetes group, from 5.46 to 2.59 per 100 patient-years, and by 47% in the type 2 diabetes group, from 1.70 to 0.90 per 100 patient-years.

The impact of Libre on DKA hospitalizations was most dramatic among those not using any test strips prior to Libre use, with a 60% reduction for the type 1 diabetes group (8.31 to 3.31 per 100 patient-years) and a 51% reduction in the type 2 diabetes group (2.51 to 1.23 per 100 patient-years).

But interestingly, the next-biggest impact was among those who had been using more than 5 test strips per day, with drops of 59% among those with type 1 diabetes (5.55 to 2.26 per 100 patient-years) and 52% in the type 2 diabetes group (1.88 to 0.90 per 100 patient-years).

This finding is important for the United States, Argento said, because some insurers, including Medicare, require that the patient performs at least 4 fingerstick glucose measurements per day to qualify for reimbursement for the Libre or any CGM system.

“I think that speaks to the importance of not requiring that patients first show they’re frequently doing self-blood glucose monitoring before they can get these devices,” he observed.

The large benefit in the high strip use group is interesting too, Argento said. “It’s a different group of people. They’re more engaged in their care...This U-shaped curve they showed is fascinating.”

Reductions in DKA hospitalizations were also similar between patients using insulin pumps and those using multiple daily injections of insulin, Roussel reported.

“It is plausible that use of the FreeStyle Libre system allowed people to detect and limit persistent hyperglycemia, and subsequently ketoacidosis,” Roussel said.

“This analysis has significant implications for patient-centered clinical care in diabetes and also for long-term health economic outcomes in the treatment of diabetes at a national level.”

All-cause hospitalizations drop 30% with Libre in type 2 diabetes

Richard M. Bergenstal, MD, executive director of the International Diabetes Center at Park Nicollet, Minneapolis, Minnesota, presented the US results, obtained from the IBM Watson Health MarketScan, a database of commercial and Medicare supplemental insurance claims for over 30 million Americans.

The study population included 2463 patients with type 2 diabetes using basal-bolus daily insulin injections but who had not previously used Libre or any other CGM, and for whom data were available 6 months prior to and after Libre initiation.

Compared with 6 months prior to Libre use, the number of acute diabetes-related events — including hyperglycemia, hypoglycemia, DKA, hypoglycemic coma, and hyperosmolarity — in the subsequent 6 months dropped by 60%, from 0.180 to 0.072 events per patient-year (P < .001).

Similarly significant reductions were seen between males and females, and among those aged ≥ 50 years or < 50 years.

All-cause hospitalizations also significantly dropped by 33% (P < 0.001), from 0.420 to 0.283 events per patient-year. Among diagnostic codes for the hospitalizations, circulatory system causes remained number one during both time periods, with little change from pre-Libre to during Libre use.

However, “endocrine, nutritional, and metabolism system” codes dropped from the second position pre-Libre (6.4 events/100 patient-years) down to the fifth position (2.6 events/100 patient-years).

And, Bergenstal noted, other major diagnostic categories that also dropped included respiratory (3.5 to 2.1 events/100 patient-years), kidney and urinary tract (3.3 to 1.7 events/100 patient-years), and hepatobiliary system and pancreas (2.4 to 1.4 events/100 patient-years).

“We’re seeing a resurgence of certain types of complications, but all of these were reduced in the 6 months after Libre,” Bergenstal pointed out.

And, pertinent to the current COVID-19 situation, “infectious and parasitic disease and disorders” dropped as well, from 4.8 to 2.8 per 100 patient-years.

Argento commented: “The fact that infections went down speaks to something that is important right now. Hyperglycemia impairs immune function chronically, but also acutely...so patients who become ill and their blood glucose deteriorates rapidly are much more likely to have a poor outcome regardless of infection. There are data for COVID-19 now.”

“These findings provide compelling support for use of [Libre] to improve both clinical outcomes and potentially reduce costs in this patient population,” Bergenstal concluded.

The Abbott FreeStyle Libre glucose monitoring system significantly reduced hospitalizations for diabetic ketoacidosis (DKA), diabetes-related emergencies, and all-cause hospitalizations among patients with diabetes, data from two new studies indicate.

The results were presented June 13 during the virtual American Diabetes Association (ADA) 80th Scientific Sessions.

One large database analysis, from France, revealed that use of the Libre system halved hospitalization rates for DKA among people with type 1 or type 2 diabetes.

In the other study, a retrospective analysis of data from over 1200 insulin-treated individuals with type 2 diabetes in the United States, use of the Libre was associated with significant reductions in both hospitalizations for acute diabetes-related emergency events and all-cause hospitalizations.

The Libre system reads glucose levels through a sensor worn on the back of the upper arm for up to 14 days. Users wave a scanner over the device to obtain a reading.

Asked to comment, Nicholas Argento, MD, diabetes technology director at Maryland Endocrine and Diabetes, Columbia, told Medscape Medical News: “One of the biggest problems with access to continuous glucose monitoring is cost. Payers need to see that there’s some cost-saving to offset the cost of paying for these devices. I think both of these studies are important for that reason.”

However, Argento also said he recommends that people with type 1 diabetes use the Dexcom continuous glucose monitor (CGM) if possible rather than the Libre, despite the former’s higher cost, because it has an alarm feature that the Libre doesn’t and is more accurate in the hypoglycemic range.

Large French study: Libre cuts DKA hospitalizations by 50%

The FreeStyle Libre system has been reimbursed in France since June 1, 2017 for patients over 4 years of age with type 1 or type 2 diabetes who take at least 3 insulin injections per day or use an insulin pump.

The new results were presented by Ronan Roussel, MD, PhD, chief of the endocrinology, diabetes, and nutrition department at Hôpital Bichat, Fédération de Diabétologie, AP-HP, Paris, France.

The DKA hospitalization data Roussel reported were part of a larger longitudinal retrospective cohort study looking at overall prescribing and use of the Libre system, and its impact on healthcare outcomes and associated costs in standard practice in France. The data came from a large nationwide claims database containing all healthcare expenses for over 66 million people.

The current study participants were 74,076 individuals with at least a full year of follow-up beginning in 2017 with the date of first reimbursement for the FreeStyle Libre system. Of those, 44.8% (33,203) had type 1 diabetes and 55.2% (40,955) had type 2 diabetes.

Prior to initiation of Libre use, about a quarter of each group was using 0 fingerstick test strips per day, about 19% of the type 1 diabetes group and 28% of the type 2 diabetes group were using 1-3 strips per day, and about half of both groups were using 4 or more strips per day.

Compared with the year prior to the date of first reimbursement for the Libre, hospitalization rates for DKA during the first year of Libre use fell by 52% in the type 1 diabetes group, from 5.46 to 2.59 per 100 patient-years, and by 47% in the type 2 diabetes group, from 1.70 to 0.90 per 100 patient-years.

The impact of Libre on DKA hospitalizations was most dramatic among those not using any test strips prior to Libre use, with a 60% reduction for the type 1 diabetes group (8.31 to 3.31 per 100 patient-years) and a 51% reduction in the type 2 diabetes group (2.51 to 1.23 per 100 patient-years).

But interestingly, the next-biggest impact was among those who had been using more than 5 test strips per day, with drops of 59% among those with type 1 diabetes (5.55 to 2.26 per 100 patient-years) and 52% in the type 2 diabetes group (1.88 to 0.90 per 100 patient-years).

This finding is important for the United States, Argento said, because some insurers, including Medicare, require that the patient performs at least 4 fingerstick glucose measurements per day to qualify for reimbursement for the Libre or any CGM system.

“I think that speaks to the importance of not requiring that patients first show they’re frequently doing self-blood glucose monitoring before they can get these devices,” he observed.

The large benefit in the high strip use group is interesting too, Argento said. “It’s a different group of people. They’re more engaged in their care...This U-shaped curve they showed is fascinating.”

Reductions in DKA hospitalizations were also similar between patients using insulin pumps and those using multiple daily injections of insulin, Roussel reported.

“It is plausible that use of the FreeStyle Libre system allowed people to detect and limit persistent hyperglycemia, and subsequently ketoacidosis,” Roussel said.

“This analysis has significant implications for patient-centered clinical care in diabetes and also for long-term health economic outcomes in the treatment of diabetes at a national level.”

All-cause hospitalizations drop 30% with Libre in type 2 diabetes

Richard M. Bergenstal, MD, executive director of the International Diabetes Center at Park Nicollet, Minneapolis, Minnesota, presented the US results, obtained from the IBM Watson Health MarketScan, a database of commercial and Medicare supplemental insurance claims for over 30 million Americans.

The study population included 2463 patients with type 2 diabetes using basal-bolus daily insulin injections but who had not previously used Libre or any other CGM, and for whom data were available 6 months prior to and after Libre initiation.

Compared with 6 months prior to Libre use, the number of acute diabetes-related events — including hyperglycemia, hypoglycemia, DKA, hypoglycemic coma, and hyperosmolarity — in the subsequent 6 months dropped by 60%, from 0.180 to 0.072 events per patient-year (P < .001).

Similarly significant reductions were seen between males and females, and among those aged ≥ 50 years or < 50 years.

All-cause hospitalizations also significantly dropped by 33% (P < 0.001), from 0.420 to 0.283 events per patient-year. Among diagnostic codes for the hospitalizations, circulatory system causes remained number one during both time periods, with little change from pre-Libre to during Libre use.

However, “endocrine, nutritional, and metabolism system” codes dropped from the second position pre-Libre (6.4 events/100 patient-years) down to the fifth position (2.6 events/100 patient-years).

And, Bergenstal noted, other major diagnostic categories that also dropped included respiratory (3.5 to 2.1 events/100 patient-years), kidney and urinary tract (3.3 to 1.7 events/100 patient-years), and hepatobiliary system and pancreas (2.4 to 1.4 events/100 patient-years).

“We’re seeing a resurgence of certain types of complications, but all of these were reduced in the 6 months after Libre,” Bergenstal pointed out.

And, pertinent to the current COVID-19 situation, “infectious and parasitic disease and disorders” dropped as well, from 4.8 to 2.8 per 100 patient-years.

Argento commented: “The fact that infections went down speaks to something that is important right now.

Roughly half of adolescents and young adults with either type 1 or type 2 diabetes for about a decade had diastolic dysfunction, a direct precursor to heart failure, in a multicenter echocardiography survey of 479 American patients.

Using tissue Doppler echocardiography findings from 258 adolescents and young adults with type 1 diabetes, and 221 with type 2 diabetes, the study found at least one imaging marker of ventricular stiffness – diastolic dysfunction – in 58% of the patients with type 2 diabetes and in 47% of those with type 1 diabetes. The type 1 patients averaged 21 years of age with a median 12 years of diagnosed disease, while the type 2 patients had an average age of 25 years and a median 11 years disease duration.

The analysis also identified several measures that significantly linked with the presence of diastolic dysfunction: older age, female sex, nonwhite race, type 2 diabetes, higher heart rate, higher body mass index, higher systolic blood pressure, and higher hemoglobin A_1c.

“Our data suggest targeting modifiable risk factors” in these patients in an effort to slow the process causing the diastolic dysfunction, Amy S. Shah, MD, said at the virtual annual scientific sessions of the American Diabetes Association. She particularly cited interventions aimed at reducing body mass index, lowering blood pressure, and improving glycemic control, as well as preventing type 2 diabetes in the first place.

Prevention of type 2 diabetes, as well as prevention of diastolic dysfunction development and progression, are key steps because of the substantial clinical consequences of diastolic dysfunction, triggered by stiffening of the left ventricle. Diastolic dysfunction leads to increased left ventricular diastolic pressure, left atrial dysfunction, and ultimately heart failure with preserved ejection fraction, a common diabetes complication that currently has no treatment with proven efficacy, said Dr. Shah, a pediatric endocrinologist and director of the Adolescent Type 2 Diabetes Program at Cincinnati Children’s Hospital Medical Center.

“It’s very concerning that diastolic dysfunction is so prevalent in this age group,” commented Robert A. Gabbay, MD, Chief Science & Medical Officer of the American Diabetes Association. “An important question is whether you can see an improvement by reversing risk factors.” He noted the importance of confirming the finding in additional cohorts as well as running prospective studies looking at the impact of risk factor modification.

Dr. Shah and her associates used data collected at four U.S. centers from patients enrolled in the SEARCH for Diabetes in Youth study who underwent a tissue Doppler examination during 2016-2019, and used three measures derived from the scans to identify diastolic dysfunction:

• The E/A ratio, which compares the early flow wave across the mitral valve (E) with the atrial flow wave (A) that occurs after atrial contraction. Lower values reflect worse pathology.
• The E/e’ ratio, which compares the early flow wave across the mitral valve (E) with the rate of cardiac wall relaxation in early diastole (e’). Higher values reflect worse pathology.
• The e’/a’ ratio, which compares the rate of cardiac wall relaxation in early diastole (e’) with the rate of cardiac wall relaxation in late diastole (a’). Lower values reflect worse pathology.

The most common abnormality involved the e’/a’ measure, which occurred in roughly 38% of the patients with type 2 diabetes and in about 23% of those with type 1 diabetes. Next most common was an abnormally high E/e’ ratio, and fewer than 10% of patients had an abnormally low E/A ratio. Both the E/A and E/e’ values were significantly worse among patients with type 2 diabetes compared with type 1 patients, while no statistically significant difference separated the two subgroups for prevalence of an e’/a’ abnormality after adjustment for body mass index, blood pressure, and HbA_1c values.

Average body mass index among the 221 studied patients with type 2 diabetes was 38 kg/m², 74% were girls or women, and 57% were non-Hispanic black and 24% non-Hispanic white. Mean blood pressure among the patients with type 2 diabetes was 123/80 mm Hg, while it was 110/72 mm Hg among the 258 patients with type 1 diabetes.

Patients with type 2 diabetes treated with the SGLT2 inhibitor empagliflozin during the landmark EMPA-REG OUTCOME trial had a solidly reduced need to either start insulin treatment or intensify existing insulin treatment, compared with those given placebo, in a post-hoc analysis of the study’s findings.

Mitchel L. Zoler/Frontline Medical News

“Empagliflozin markedly and durably delayed the need for insulin initiation, and reduced the need for large dose increases in patients already using insulin,” Muthiah Vaduganathan, MD, said at the virtual annual scientific sessions of the American Diabetes Association.

The patients in the empagliflozin (Jardiance) arm of EMPA-REG OUTCOME had a 9% rate of initiating insulin treatment after 4 years in the study, compared with a 20% rate among patients who received placebo, a statistically significant 60% relative risk reduction. All patients in the trial continued on their background oral glucose-lowering medications.

Among the 48% of study patients who entered the study already using insulin as part of their usual regimen, 18% of those receiving empagliflozin required a significant increase in their insulin dosage (an increase of at least 20% from baseline) after 4 years. But among the control patients, 35% needed this level of insulin-dosage intensification, again a statistically significant difference that computed to a 58% relative reduction in the need for boosting the insulin dosage.

For both of these endpoints, the divergence between the empagliflozin and control arms became apparent within the first 6 months on treatment, and the between-group differences steadily increased during further follow-up. The analyses pooled the patients who received empagliflozin in the trial, which studied two different dosages of the drug.

Results add to the ‘risk and benefit conversation’

“This is one of the first studies to look at this question in a more granular fashion” in patients with type 2 diabetes receiving a drug from the sodium-glucose cotransporter 2 (SGLT2) inhibitor class, said Dr. Vaduganathan, a cardiologist at Brigham and Women’s Hospital in Boston. It provides “compelling” information to include when discussing oral diabetes-drug options with patients, he said in an interview.

Patients newly diagnosed with type 2 diabetes “often think about insulin” and their potential need to eventually start taking it, with the requirements it brings for training, monitoring, and drug delivery, along with the costs for insulin and glucose monitoring. “Patients are very attuned to potentially needing insulin and often ask about it. A reduced need for insulin will be an important part of the risk and benefit conversation” with patients about potential use of an SGLT2 inhibitor, he said.

Dr. Vaduganathan hypothesized that three factors could contribute to the impact of empagliflozin on insulin initiation and dosage level: a direct glycemic-control effect of the drug, the drug’s positive impact on overall well-being and function that could enhance patient movement, and the documented ability of treatment with empagliflozin and other drugs in its class to cut the rate of heart failure hospitalizations.

Handelsman: Analysis shows no ‘spectacular effect’

The association of empagliflozin treatment with a reduced need for insulin seen in these data is consistent with expectations for patients with type 2 diabetes who receive an additional oral drug, commented Yehuda Handelsman, MD, an endocrinologist and diabetes specialist who is medical director of The Metabolic Institute of American in Tarzana, Calif. “In large part it has to do with patients on placebo having to get more insulin” because their additional oral-drug options were limited. Dr. Handelsman pointed out that during the period when the EMPA-REG OUTCOME trial ran, from 2010-2015, fewer oral drugs were available than today, and clinicians in the study were encouraged to treat patients to their goal glycemia level according to local guidelines. In addition to a modest but useful glycemic control effect from SGLT2 inhibitors that, on average, cut hemoglobin A_1c levels by about 0.5%, they may also give a small boost to insulin sensitivity that can also defer the need to add or increase insulin. The level of insulin-treatment deference reported in the new analysis was “not a spectacular effect” he said in an interview.

The EMPA-REG OUTCOME (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients) study followed 7,020 patients at 590 sites in 42 countries for a median of 3.1 years. The study’s primary endpoint was a composite of death from cardiovascular causes, nonfatal myocardial infarction (excluding silent MI), or nonfatal stroke, and the results showed a statistically significant 14% relative risk reduction with empagliflozin treatment (N Engl J Med. 2015 Nov 26;373[22]:2117-28 ). The results also showed that 12 weeks into the study, before patients could receive any additional drugs, HbA_1c levels averaged 0.54%-0.6% lower among the empagliflozin-treated patients than those in the placebo arm, with smaller between-group differences maintained through the balance of the study. At entry, more than half the enrolled patients were routinely treated with metformin, and close to half were receiving a sulfonyurea agent.

The EMPA-REG OUTCOME results were also notable as showing for the first time that treatment with an SGLT2 inhibitor drug produced a substantial decrease in heart failure hospitalizations, incident heart failure, and progression of renal dysfunction, effects subsequently confirmed and also found for other agents in this drug class.

EMPA-REG OUTCOME was funded in part by Boehringer Ingelheim and Eli Lilly, the companies that market empagliflozin (Jardiance).

Patients with type 2 diabetes treated with the SGLT2 inhibitor empagliflozin during the landmark EMPA-REG OUTCOME trial had a solidly reduced need to either start insulin treatment or intensify existing insulin treatment, compared with those given placebo, in a post-hoc analysis of the study’s findings.

“Empagliflozin markedly and durably delayed the need for insulin initiation, and reduced the need for large dose increases in patients already using insulin,” Muthiah Vaduganathan, MD, said at the virtual annual scientific sessions of the American Diabetes Association.

The patients in the empagliflozin (Jardiance) arm of EMPA-REG OUTCOME had a 9% rate of initiating insulin treatment after 4 years in the study, compared with a 20% rate among patients who received placebo, a statistically significant 60% relative risk reduction. All patients in the trial continued on their background oral glucose-lowering medications.

Among the 48% of study patients who entered the study already using insulin as part of their usual regimen, 18% of those receiving empagliflozin required a significant increase in their insulin dosage (an increase of at least 20% from baseline) after 4 years. But among the control patients, 35% needed this level of insulin-dosage intensification, again a statistically significant difference that computed to a 58% relative reduction in the need for boosting the insulin dosage.

For both of these endpoints, the divergence between the empagliflozin and control arms became apparent within the first 6 months on treatment, and the between-group differences steadily increased during further follow-up. The analyses pooled the patients who received empagliflozin in the trial, which studied two different dosages of the drug.

Results add to the ‘risk and benefit conversation’

“This is one of the first studies to look at this question in a more granular fashion” in patients with type 2 diabetes receiving a drug from the sodium-glucose cotransporter 2 (SGLT2) inhibitor class, said Dr. Vaduganathan, a cardiologist at Brigham and Women’s Hospital in Boston. It provides “compelling” information to include when discussing oral diabetes-drug options with patients, he said in an interview.

Patients newly diagnosed with type 2 diabetes “often think about insulin” and their potential need to eventually start taking it, with the requirements it brings for training, monitoring, and drug delivery, along with the costs for insulin and glucose monitoring. “Patients are very attuned to potentially needing insulin and often ask about it. A reduced need for insulin will be an important part of the risk and benefit conversation” with patients about potential use of an SGLT2 inhibitor, he said.

Dr. Vaduganathan hypothesized that three factors could contribute to the impact of empagliflozin on insulin initiation and dosage level: a direct glycemic-control effect of the drug, the drug’s positive impact on overall well-being and function that could enhance patient movement, and the documented ability of treatment with empagliflozin and other drugs in its class to cut the rate of heart failure hospitalizations. This last feature is potentially relevant because insulin treatment often starts in patients with type 2 diabetes during a hospitalization, he noted.

New preliminary data from the T1D Exchange suggest that, although hyperglycemia and diabetic ketoacidosis (DKA) are common in people with type 1 diabetes who develop COVID-19, many are still able to manage the illness at home and overall mortality is relatively low.

The new findings – the first US data on individuals with type 1 diabetes and COVID-19 – were published online June 5 in Diabetes Care by Osagie A. Ebekozien, MD, vice president, quality improvement and population health at the T1D Exchange, and colleagues.

Two UK studies are the only prior ones to previously examine the topic.

The newly published study includes data as of May 5 on 64 individuals from a total of 64 US sites, including 15 T1D Exchange member clinics and an additional 49 endocrinology clinics from around the country. Since the paper was submitted, there are now 220 patients from 68 sites. Another publication with a more detailed analysis of risk factors and adjustment for confounders is planned for later this year.

Some of the findings from the preliminary data have shifted, but many aspects remain consistent, Ebekozien told Medscape Medical News.

“One thing still very true, even with the unpublished findings, is the influence of A1c and glycemic management. ...With higher A1c levels, we’re seeing more COVID-19 hospitalizations and worse outcomes,” he said.

And as has been generally reported for COVID-19, high body mass index was a major risk factor in the preliminary dataset – and remains so.

There were two deaths in the preliminary report, both individuals with comorbidities in addition to type 1 diabetes, Ebekozien said. There have been a few more deaths in the larger dataset, but the mortality rate remains relatively low.

Interestingly, females predominate in both cohorts. That may be a reporting phenomenon, another factor that is being analyzed.

Hyperglycemia Remains a Major Risk Factor

The study is specifically being conducted by the T1D Exchange’s Quality Improvement Collaborative, which Ebekozien heads.

Data were obtained for 33 patients with type 1 diabetes who tested positive for COVID-19, and another 31 who were classified as “COVID-19–like” because they had symptoms consistent with COVID-19, as identified by the Centers for Disease Control and Prevention, but hadn’t been tested for the virus.

For all 64 patients, the mean age was 20.9 years and two thirds (65.6%) were aged 18 or younger. A higher proportion of the COVID-19–like patients were pediatric than the confirmed cases. The larger dataset includes more adult patients, Ebekozien told Medscape Medical News.

Overall, 60.9% of patients were female. Nearly half were white, a quarter Hispanic, and 18.8% black. More confirmed COVID-19 cases were black compared with suspected cases (30.3% vs 6.5%).

Median A1c for the overall group (including suspected COVID-19 cases) was 8.0%, but it was 8.5% among confirmed cases. Overall, six patients (9.8%) presented with new-onset type 1 diabetes after they developed COVID-19.

Hyperglycemia was present in half (32) of patients overall. DKA occurred in 19 people (30.2%): 15 of the confirmed COVID-19 cases (45.5%) versus just 4 (13.3%) of the COVID-19–like cases. Nausea was reported in 30.2% of patients overall.

Other symptoms were typical of COVID-19, including fever (41.3%), dry cough (38.1%), and shortness of breath (27.0%). Loss of taste and smell was less common, at just 9.5% overall.

Obesity was present in 39.7% of patients overall, with similar proportions in the confirmed and suspected COVID-19 groups. Hypertension and/or cardiovascular disease were present in 14.3% of patients overall, and the rate was similar between the two subgroups.

One of the two patients who died was a 79-year-old man who had hypertension and a prior stroke in addition to type 1 diabetes. The other was a 19-year-old woman with a history of asthma who developed a pulmonary embolism during the onset of COVID-19. Neither had DKA.

Even in Type 1 Diabetes, COVID-19 Can Be Managed at Home

Overall, 34.9% of patients were able to manage COVID-19 entirely at home, with 27.3% of the confirmed and 43.3% of the suspected cases able to do so.

At the other extreme, 22.2% of patients overall were admitted to the intensive care unit; 30.3% of the confirmed versus 13.3% of suspected cases.

Including the small proportion of patients sent home after being seen in emergency or urgent care, overall roughly half were not admitted to hospital.

“Interestingly, even in this preliminary study, half were managed at home via telemedicine with an endocrinologist and infectious disease specialist. ... I think it continues to be a case-by-case clinical decision between the patient and their provider,” Ebekozien said.

“But, we’re seeing a good number of patients who are managed at home and the symptoms resolve in a week or two, and the illness runs its course, and they don’t have to even be seen,” he added.

The research team is also collecting data on barriers to remote care, including challenges with telemedicine and how frontline providers are navigating them.

“Those are all things that our future paper will be able to shed more light on,” he explained.

Endocrinologists around the country are invited to report cases of COVID-19 in patients with type 1 diabetes to the T1D Exchange by emailing [email protected].

And in fact, Ebekozien also requested that clinicians with a large type 1 diabetes population also report if they’ve had no COVID-19 cases.

“Even if they haven’t had a case, that’s very useful information for us to know. One of the things we want to calculate down the line is the incidence ratio. Not all participating sites have had a case.”

Endocrinologists from all the participating sites have formed a dedicated community that meets regularly via webinars to share information, he noted. “It’s been a very selfless effort to work collaboratively as a community to quickly answer critical questions.”
