Emergencies happen anywhere, anytime – and sometimes physicians find themselves in situations where they are the only ones who can help. “Is There a Doctor in the House?” is a new series telling these stories.

When the plane crashed, I was asleep. I had arrived the evening before with my wife and three sons at a house on Kezar Lake on the Maine–New Hampshire border. We were going to spend a week there with my wife’s four brothers and their families. I was woken by people screaming my name. I jumped out of bed and ran downstairs. My kids had been watching a float plane circling and gliding along the lake. It had crashed into the water and flipped upside down. My oldest brother-in-law jumped into his ski boat and we sped out to the scene.

All we can see are the plane’s pontoons. The rest is underwater. A woman has already surfaced, screaming. I dive in.

I find the woman’s husband and 3-year-old son struggling to get free from the plane through the smashed windshield. They manage to get to the surface. The pilot is dead, impaled through the chest by the left wing strut.

The big problem: A little girl, whom I would learn later is named Lauren, remained trapped. The water is murky but I can see her, a 5- or 6-year-old girl with this long hair, strapped in upside down and unconscious.

The mom and I dive down over and over, pulling and ripping at the door. We cannot get it open. Finally, I’m able to bend the door open enough where I can reach in, but I can’t undo the seatbelt. In my mind, I’m debating, should I try and go through the front windshield? I’m getting really tired, I can tell there’s fuel in the water, and I don’t want to drown in the plane. So I pop up to the surface and yell, “Does anyone have a knife?”

My brother-in-law shoots back to shore in the boat, screaming, “Get a knife!” My niece gets in the boat with one. I’m standing on the pontoon, and my niece is in the front of the boat calling, “Uncle Todd! Uncle Todd!” and she throws the knife. It goes way over my head. I can’t even jump for it, it’s so high.

I have to get the knife. So, I dive into the water to try and find it. Somehow, the black knife has landed on the white wing, 4 or 5 feet under the water. Pure luck. It could have sunk down a hundred feet into the lake. I grab the knife and hand it to the mom, Beth. She’s able to cut the seatbelt, and we both pull Lauren to the surface.

I lay her out on the pontoon. She has no pulse and her pupils are fixed and dilated. Her mom is yelling, “She’s dead, isn’t she?” I start CPR. My skin and eyes are burning from the airplane fuel in the water. I get her breathing, and her heart comes back very quickly. Lauren starts to vomit and I’m trying to keep her airway clear. She’s breathing spontaneously and she has a pulse, so I decide it’s time to move her to shore.

We pull the boat up to the dock and Lauren’s now having anoxic seizures. Her brain has been without oxygen, and now she’s getting perfused again. We get her to shore and lay her on the lawn. I’m still doing mouth-to-mouth, but she’s seizing like crazy, and I don’t have any way to control that. Beth is crying and wants to hold her daughter gently while I’m working.

Someone had called 911, and finally this dude shows up with an ambulance, and it’s like something out of World War II. All he has is an oxygen tank, but the mask is old and cracked. It’s too big for Lauren, but it sort of fits me, so I’m sucking in oxygen and blowing it into the girl’s mouth. I’m doing whatever I can, but I don’t have an IV to start. I have no fluids. I got nothing.

As it happens, I’d done my emergency medicine training at Maine Medical Center, so I tell someone to call them and get a Life Flight chopper. We have to drive somewhere where the chopper can land, so we take the ambulance to the parking lot of the closest store called the Wicked Good Store. That’s a common thing in Maine. Everything is “wicked good.”

The whole town is there by that point. The chopper arrives. The ambulance doors pop open and a woman says, “Todd?” And I say, “Heather?”

Heather is an emergency flight nurse whom I’d trained with many years ago. There’s immediate trust. She has all the right equipment. We put in breathing tubes and IVs. We stop Lauren from seizing. The kid is soon stable.

There is only one extra seat in the chopper, so I tell Beth to go. They take off.

Suddenly, I begin to doubt my decision. Lauren had been underwater for 15 minutes at minimum. I know how long that is. Did I do the right thing? Did I resuscitate a brain-dead child? I didn’t think about it at the time, but if that patient had come to me in the emergency department, I’m honestly not sure what I would have done.

So, I go home. And I don’t get a call. The FAA and sheriff arrive to take statements from us. I don’t hear from anyone.

The next day I start calling. No one will tell me anything, so I finally get to one of the pediatric ICU attendings who had trained me. He says Lauren literally woke up and said, “I have to go pee.” And that was it. She was 100% normal. I couldn’t believe it.

Here’s a theory: In kids, there’s something called the glottic reflex. I think her glottic reflex went off as soon as she hit the water, which basically closed her airway. So when she passed out, she could never get enough water in her lungs and still had enough air in there to keep her alive. Later, I got a call from her uncle. He could barely get the words out because he was in tears. He said Lauren was doing beautifully.  

Three days later, I drove to Lauren’s house with my wife and kids. I had her read to me. I watched her play on the jungle gym for motor function. All sorts of stuff. She was totally normal.

Beth told us that the night before the accident, her mother had given the women in her family what she called a “miracle bracelet,” a bracelet that is supposed to give you one miracle in your life. Beth said she had the bracelet on her wrist the day of the accident, and now it’s gone. “Saving Lauren’s life was my miracle,” she said.

Funny thing: For 20 years, I ran all the EMS, police, fire, ambulance, in Boulder, Colo., where I live. I wrote all the protocols, and I would never advise any of my paramedics to dive into jet fuel to save someone. That was risky. But at the time, it was totally automatic. I think it taught me not to give up in certain situations, because you really don’t know.

In a recent column, I cautiously discussed what has been called gender-affirming or transgender care.

In the days following the appearance of that Letters From Maine column on this topic, I received an unusual number of responses from readers suggesting I had touched on a topic that was on the minds of many pediatricians.

Since then, the Florida Board of Medicine and Osteopathic Medicine voted to forbid physicians from prescribing puberty blockers and hormones and/or performing surgeries in patients under age 18 who were seeking transgender care. Children already receiving treatments were exempt from the ruling. The osteopathic board added a second exception in cases where the child was a participant in a research protocol. The board of medicine inexplicably did not include this exception.

Regardless of how one feels about the ethics and the appropriateness of transgender care, it is not an issue to be decided by a politically appointed entity.

As I look back over what I have learned by watching this tragic drama play out, I am struck by a distinction that has yet to receive enough attention. When we are discussing gender dysphoria we are really talking about two different pediatric populations and scenarios. There is the child who from a very young age has consistently preferred to dress and behave in a manner that is different from the gender he or she was assigned at birth. The management of this child is a challenge that requires a careful balance of support and protection from the harsh realities of the gender-regimented world.

The second scenario stars the adolescent who has no prior history of gender dysphoria, or at least no outward manifestations. Then, faced by the challenges of puberty and adolescence, something or things happen that erupt into a full-blown gender-dysphoric storm. We currently have very little understanding of what those “things” are.

Each population can probably be further divided into subgroups – and that’s just the point. Every gender-dysphoric child, whether their dysphoria began at age 2 or 12, is an individual with a unique family dynamic and socioeconomic background. They may share some as yet unknown genetic signature, but in our current state of ignorance they deserve, as do all of our patients, to be treated as individuals by their primary care physicians and consultants who must at first do no harm. One size does not fit all and certainly their care should not be dictated by a politically influenced entity.

PHILADELPHIA – What works in the clinic can also work in community settings: Patients who are overweight or obese with knee osteoarthritis can find relief from pain through diet and exercise programs conducted in recreation centers, local gyms, fitness centers, and other places close to home, according to investigators in a pragmatic randomized trial.

The Weight Loss and Exercise for Communities With Arthritis in North Carolina (WE-CAN) study was modeled after the successful Intensive Diet and Exercise for Arthritis trial, which showed that adults randomized to 18 months of either a diet and exercise program or diet alone had more weight loss and larger reductions in levels of the inflammatory cytokine interleukin-6 than patients randomized to exercise alone, and that diet alone was associated with greater reductions in knee compressive force than exercise alone.

That study was conducted by Stephen P. Messier, PhD, and colleagues at Wake Forest University, Winston-Salem, N.C.. As previously reported, the investigators also saw continued benefits for participants years after the original trial.

With the WE-CAN trial, results of which were reported at the annual meeting of the American College of Rheumatology, Dr. Messier and colleagues took the intervention one step further, randomizing 823 community-dwelling adults who were overweight or obese (body mass index [BMI], ≥ 27 kg/m2) with knee OA to either an 18-month diet and exercise intervention or attention control group consisting of five 1-hour face-to-face meetings over 18 months, plus information packets and phone sessions during alternate months.

“Compared to the control group, diet plus exercise had a statistically significant but modest reduction in pain. Diet plus exercise was 20% more likely to attain a clinically important 2-point improvement in pain,” Dr. Messier said in an oral abstract session at ACR.
 

Real-world setting

The primary goal of WE-CAN was to “determine whether adaptation of a diet and exercise academic center–based efficacy trial to community settings results in a statistically significant reduction in pain relative to an attention control.”

A total of 3,751 potential candidates were screened, and 823 were randomized and assigned to either a diet and exercise arm (414) or attention control arm (409). Of the patients randomized, 336 in the diet/exercise arm and 322 in the control arm attended the final 18-month follow-up visit.

The exercise component consisted of a 15-minute walking period, followed by a 20-minute weight-training period, and ending with a second 15-minute walking period. The diet goal was 10% or greater weight loss, aided by a distribution of low-calorie recipes to produce a reduced-calorie diet of the patient’s choice, with the option to include nutritional powder to make low-calories shakes as meal replacements, one or two per day for the first 6 months, with the option of one per day for the remaining months.

The pragmatic components included the use of established community facilities in both urban and rural counties in North Carolina, broad inclusion criteria, patient-centered outcomes, use of community-based staff to deliver the treatment, nonphysicians trained by study physicians to perform knee exams, and various means of communication, Dr. Messier said.

Participants in each arm were closely matched by demographic and clinical characteristics, with a mean age of 64.5 years in the diet/exercise group and 64.7 years in the attention control group, respective mean weight of 100.7 kg and 101.1 kg, and respective BMI of 36.7 and 36.9. Women comprised about 77% of participants in each group.
 

Endpoints met

The trial met its primary endpoint of a significantly greater reduction in pain at 18 months in the diet and exercise group as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and scored on a scale of 0 (no pain) to 20 (worst pain).

In an analysis adjusted for sex, BMI, and baseline values, there was a 32% reduction in pain scores from baseline in the active intervention arm versus 24% in the control arm (P = .02).

In all, 60.2% of participants assigned to diet and exercise had a minimum reduction in pain scores of at least 2 points at 18 months, compared with 49.7% of participants assigned to the attention control group. This translated into a relative risk for achieving at least a 2-point improvement with diet and exercise was 1.20 (P = .01).

Among participants who remained in the study for the entire 18 months, there were significant improvements in the diet and exercise group compared with controls in the prespecified secondary endpoints of weight change (–8 kg vs. –2 kg), waist circumference, WOMAC function, 6-minute walk distance, and mean Short Form–36 health-related quality of life subscale (P < .001 for all comparisons).

Dr. Messier acknowledged that the diagnosis of knee OA was based only on ACR clinical criteria and was not confirmed with imaging. In addition, offering patients the option of free meal replacement limited the pragmatic nature of the intervention.

He also noted that the 24% reduction in pain seen in the control group suggests that interacting with patients can improve clinical outcomes.
 

‘Tour de force’

In the question-and-answer session following Dr. Messier’s presentation, David T. Felson, MD, a rheumatologist at Boston Medical Center, called in and said the study was “a tour de force” and congratulated Dr. Messier and colleagues on “a lovely study.”

Dr. Felson asked whether the investigators had conducted a mediation analysis to determine what proportion of the improvement was attributable to weight loss, and whether patients assigned to exercise were sticking with it throughout the study.

Dr. Messier replied that they had not yet done a mediation analysis but were continuing to examine the data. Regarding the exercise question, he noted that “the adherence was over 80% for 6 months and over 70% for the whole 18 months, so they did a really nice job.”

In an interview, session moderator Anne Davidson, MBBS, director of the rheumatology program at Northwell Health in Manhasset, N.Y., commented that the investigators managed to accomplish a very challenging task.

“In terms of recruitment of patients with engagement of community facilities and quality of data, I would say that, as far as an osteoarthritis study goes, this was really a tremendous effort on the part of all people involved,” she said.

She noted that, while the WE-CAN program may work in North Carolina, there may be barriers to implementing it elsewhere, such as large suburban areas where some patients experience food insecurity and others have difficulty with transportation and access to treatment facilities.

“The question here that remains is, as Dr. Felson asked, what is the contribution of weight loss and what is the contribution of exercise? Because if it’s just weight loss, we have a whole lot of new things coming to help with that,” she said.

The WE-CAN study was supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Messier disclosed that GNC, a health food and nutrition chain, donated the meal replacements used by patients. Dr. Davidson reported no relevant conflicts of interest.

PHILADELPHIA – What works in the clinic can also work in community settings: Patients who are overweight or obese with knee osteoarthritis can find relief from pain through diet and exercise programs conducted in recreation centers, local gyms, fitness centers, and other places close to home, according to investigators in a pragmatic randomized trial.

The Weight Loss and Exercise for Communities With Arthritis in North Carolina (WE-CAN) study was modeled after the successful Intensive Diet and Exercise for Arthritis trial, which showed that adults randomized to 18 months of either a diet and exercise program or diet alone had more weight loss and larger reductions in levels of the inflammatory cytokine interleukin-6 than patients randomized to exercise alone, and that diet alone was associated with greater reductions in knee compressive force than exercise alone.

That study was conducted by Stephen P. Messier, PhD, and colleagues at Wake Forest University, Winston-Salem, N.C.. As previously reported, the investigators also saw continued benefits for participants years after the original trial.

With the WE-CAN trial, results of which were reported at the annual meeting of the American College of Rheumatology, Dr. Messier and colleagues took the intervention one step further, randomizing 823 community-dwelling adults who were overweight or obese (body mass index [BMI], ≥ 27 kg/m2) with knee OA to either an 18-month diet and exercise intervention or attention control group consisting of five 1-hour face-to-face meetings over 18 months, plus information packets and phone sessions during alternate months.

“Compared to the control group, diet plus exercise had a statistically significant but modest reduction in pain. Diet plus exercise was 20% more likely to attain a clinically important 2-point improvement in pain,” Dr. Messier said in an oral abstract session at ACR.
 

Real-world setting

The primary goal of WE-CAN was to “determine whether adaptation of a diet and exercise academic center–based efficacy trial to community settings results in a statistically significant reduction in pain relative to an attention control.”

A total of 3,751 potential candidates were screened, and 823 were randomized and assigned to either a diet and exercise arm (414) or attention control arm (409). Of the patients randomized, 336 in the diet/exercise arm and 322 in the control arm attended the final 18-month follow-up visit.

The exercise component consisted of a 15-minute walking period, followed by a 20-minute weight-training period, and ending with a second 15-minute walking period. The diet goal was 10% or greater weight loss, aided by a distribution of low-calorie recipes to produce a reduced-calorie diet of the patient’s choice, with the option to include nutritional powder to make low-calories shakes as meal replacements, one or two per day for the first 6 months, with the option of one per day for the remaining months.

The pragmatic components included the use of established community facilities in both urban and rural counties in North Carolina, broad inclusion criteria, patient-centered outcomes, use of community-based staff to deliver the treatment, nonphysicians trained by study physicians to perform knee exams, and various means of communication, Dr. Messier said.

Participants in each arm were closely matched by demographic and clinical characteristics, with a mean age of 64.5 years in the diet/exercise group and 64.7 years in the attention control group, respective mean weight of 100.7 kg and 101.1 kg, and respective BMI of 36.7 and 36.9. Women comprised about 77% of participants in each group.
 

Endpoints met

The trial met its primary endpoint of a significantly greater reduction in pain at 18 months in the diet and exercise group as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and scored on a scale of 0 (no pain) to 20 (worst pain).

In an analysis adjusted for sex, BMI, and baseline values, there was a 32% reduction in pain scores from baseline in the active intervention arm versus 24% in the control arm (P = .02).

In all, 60.2% of participants assigned to diet and exercise had a minimum reduction in pain scores of at least 2 points at 18 months, compared with 49.7% of participants assigned to the attention control group. This translated into a relative risk for achieving at least a 2-point improvement with diet and exercise was 1.20 (P = .01).

Among participants who remained in the study for the entire 18 months, there were significant improvements in the diet and exercise group compared with controls in the prespecified secondary endpoints of weight change (–8 kg vs. –2 kg), waist circumference, WOMAC function, 6-minute walk distance, and mean Short Form–36 health-related quality of life subscale (P < .001 for all comparisons).

Dr. Messier acknowledged that the diagnosis of knee OA was based only on ACR clinical criteria and was not confirmed with imaging. In addition, offering patients the option of free meal replacement limited the pragmatic nature of the intervention.

He also noted that the 24% reduction in pain seen in the control group suggests that interacting with patients can improve clinical outcomes.
 

‘Tour de force’

In the question-and-answer session following Dr. Messier’s presentation, David T. Felson, MD, a rheumatologist at Boston Medical Center, called in and said the study was “a tour de force” and congratulated Dr. Messier and colleagues on “a lovely study.”

Selecting the best medication regimen for a patient with type 2 diabetes mellitus (T2DM) depends on many factors, such as glycemic control, adherence, adverse effect (AE) profile, and comorbid conditions.¹ Selected agents from 2 newer medication classes, glucagon-like peptide 1 receptor agonists (GLP-1 RA) and sodium-glucose cotransporter 2 inhibitors (SGLT2i), have demonstrated cardiovascular and renal protective properties, creating a new paradigm in management.

The American Diabetes Association recommends medications with proven benefit in cardiovascular disease (CVD), such as the GLP-1 RAs liraglutide, injectable semaglutide, or dulaglutide, or the SGLT2i empagliflozin or canagliflozin, as second-line after metformin in patients with established atherosclerotic CVD or indicators of high risk to reduce the risk of major adverse cardiovascular events (MACE).¹ SGLT2i are preferred in patients with diabetic kidney disease, and GLP-1 RAs are next in line for selection of agents with proven nephroprotection (liraglutide, injectable semaglutide, dulaglutide). The mechanisms of these benefits are not fully understood but may be due to their extraglycemic effects. The classes likely induce these benefits by different mechanisms: SGLT2i by hemodynamic effects and GLP-1 RAs by anti-inflammatory mechanisms.² Although there is much interest, evidence is limited regarding the cardiovascular and renal protection benefits of these agents used in combination.

The combined use of GLP-1 RA and SGLT2i agents demonstrated greater benefit than separate use in trials with nonveteran populations.^3-7 These studies evaluated effects on hemoglobin A_1c (HbA_1c) levels, weight loss, blood pressure (BP), and estimated glomerular filtration rate (eGFR).A meta-analysis of 7 trials found that the combination of GLP-1 RA and SGLT2i reduced HbA_1c levels, body weight, and systolic blood pressure (SBP).⁸ All of the changes were statistically significant except for body weight with combination vs SGLT2i alone. Combination therapy was not associated with increased risk of severe hypoglycemia compared with either therapy separately.

The purpose of our study was to evaluate the safety and efficacy of the combined use of GLP-1 RA and SGLT2i in a real-world, US Department of Veterans Affairs (VA) population with T2DM.

Methods

This study was a pre-post, retrospective, single-center chart review. Subjects served as their own control. The project was reviewed and approved by the VA Ann Arbor Healthcare System Institutional Review Board. Subjects prescribed both a GLP-1 RA (semaglutide or liraglutide) and SGLT2i (empagliflozin) between January 1, 2014, and November 10, 2019, were extracted from the Corporate Data Warehouse (CDW) for possible inclusion in the study.

Patients were excluded if they received < 12 weeks of combination GLP-1 RA and SGLT2i therapy or did not have a corresponding 12-week HbA_1c level. Patients also were excluded if they had < 12 weeks of monotherapy before starting combination therapy or did not have a baseline HbA_1c level, or if the start date of combination therapy was not recorded in the VA electronic health record (EHR). We reviewed data for each patient from 6 months before to 1 year after the second agent was started. Start of the first agent (GLP-1 RA or SGLT2i) was recorded as the date the prescription was picked up in-person or 7 days after release date if mailed to the patient. Start of the second agent (GLP-1 RA or SGLT2i) was defined as baseline and was the date the prescription was picked up in person or 7 days after the release date if mailed.

Baseline measures were taken anytime from 8 weeks after the start of the first agent through 2 weeks after the start of the second agent. Data collected included age, sex, race, height, weight, BP, HbA_1c levels, serum creatinine (SCr), eGFR, classes of medications for the treatment of T2DM, and the number of prescribed antihypertensive medications. HbA_1c levels, SCr, eGFR, weight, and BP also were collected at 12 weeks (within 8-21 weeks); 26 weeks (within 22-35 weeks); and 52 weeks (within 36-57 weeks) of combination therapy. We reviewed progress notes and laboratory results to determine AEs within 26 weeks before initiating second agent (baseline) and 0 to 26 weeks and 26 to 52 weeks after initiating combination therapy.

The primary objective was to determine the effect on HbA_1c levels at 12 weeks when using a GLP-1 RA and SGLT2i in combination vs separately. Secondary objectives were to determine change from baseline in mean body weight, BP, SCr, and eGFR at 12, 26, and 52 weeks; change in HbA_1c levels at 26 and 52 weeks; and incidence of prespecified adverse drug reactions during combination therapy vs separately.

Statistical Analysis

Assuming a SD of 1, 80% power, significance level of P < .05, 2-sided test, and a correlation between baseline and follow-up of 0.5, we determined that a sample size of 34 subjects was required to detect a 0.5% change in baseline HbA_1c level at 12 weeks. A t test (or Wilcoxon signed rank test if outcome not normally distributed) was conducted to examine whether the expected change from baseline was different from 0 for continuous outcomes. Median change from baseline was reported for SCr as a nonparametric t test (Wilcoxon signed rank test) was used.

Results

We identified 110 patients for possible study inclusion and 39 met eligibility criteria. After record review, 30 patients were excluded for receiving < 12 weeks of combination therapy or no 12 week HbA_1c level; 26 patients were excluded for receiving < 12 weeks of monotherapy before starting combination therapy or no baseline HbA_1c level; and 15 patients were excluded for lack of documentation in the VA EHR. Of the 39 patients included, 24 (62%) were prescribed empagliflozin first and then 8 started liraglutide and 16 started semaglutide.

HbA_1c levels decreased by 1% after 12 weeks of combination therapy compared with baseline (P < .001), and this reduction was sustained through the duration of the study period (Table 2).

Discussion

This study evaluated the safety and efficacy of combined use of semaglutide or liraglutide and empagliflozin in a veteran population with T2DM. The retrospective chart review captured real-world practice and outcomes. Combination therapy was associated with a significant reduction in HbA_1c levels, body weight, and SBP compared with either agent alone. No significant change was seen in DBP, SCr, or eGFR. Overall, the combination of GLP-1 RA and SGLT2i medications demonstrated a good safety profile with most patients reporting no AEs.

Several other studies have assessed the safety and efficacy of using GLP-1 RA and SGLT2i in combination. The DURATION 8 trial is the only double-blind trial to randomize subjects to receive either exenatide once weekly, dapagliflozin, or the combination of both for up to 52 weeks.³ Other controlled trials required stable background therapy with either SGLT2i or GLP-1 RA before randomization to receive the other class or placebo and had durations between 18 and 30 weeks.^4-7 The AWARD 10 trial studied the combination of canagliflozin and dulaglutide, which both have proven CVD benefit.⁴ Other studies did not restrict SGLT2i or GLP-1 RA background therapy to agents with proven CVD benefit.^5-7 The present study evaluated the combination of empagliflozin plus liraglutide or semaglutide, agents that all have proven CVD benefit.

A meta-analysis of 7 trials, including those previously mentioned, was conducted to evaluate the combination of GLP-1 RA and SGLT2i.⁸ The combination significantly reduced HbA_1c levels by 0.61% and 0.85% compared with GLP-1 RA or SGLT2i, respectively. Our trial showed greater HbA_1c level reduction of 1% with combination therapy compared with either agent separately. This may have been due in part to a higher baseline HbA_1c level in our real-world veteran population. The meta-analysis found the combination decreased body weight 2.6 kg and 1.5 kg compared with GLP-1 RA or SGLT2i, respectively.⁸ This only reached significance with comparison vs GLP-1 RA alone. Our study demonstrated impressive weight loss of up to about 5 kg after 26 and 52 weeks of combination therapy. This is equivalent to about 5% weight loss from baseline, which is clinically significant.⁹ Liraglutide and semaglutide are the GLP-1 RAs associated with the greatest weight loss, which may contribute to greater weight loss efficacy seen in the present trial.¹

In our trial SBP fell lower compared with the meta-analysis. Combination therapy significantly reduced SBP by 4.1 mm Hg and 2.7 mm Hg compared with GLP-1 RA or SGLT2i, respectively, in the meta-analysis.⁸ We observed a significant 9 to 12 mm Hg reduction in SBP after 26 to 52 weeks of combination therapy compared with baseline. This reduction occurred despite relatively controlled SBP at baseline (135 mm Hg). Each reduction of 10 mm Hg in SBP significantly reduces the risk of MACE, stroke, and heart failure, making our results clinically significant.¹⁰ Neither the meta-analysis nor present study found a significant difference in DBP or eGFR with combination therapy.

AEs were similar in this trial compared with the meta-analysis. Combination treatment with GLP-1 RA and SGLT2i did not increase the incidence of severe hypoglycemia in either study.⁸ Hypoglycemia was the most common AE in this study, but frequency was similar with combination and separate therapy. Both medication classes are associated with low or no risk of hypoglycemia on their own.¹ Baseline medications likely contributed to episodes of hypoglycemia seen in this study: About 80% of patients were prescribed basal insulin, 15% were prescribed a sulfonylurea, and 13% were prescribed prandial insulin. There is limited overlap between the known AEs of GLP-1 RA and SGLT2i, making combination therapy a safe option for use in patients with T2DM.

Our study confirms greater reduction in HbA_1c levels, weight, and SBP in veterans taking GLP-1 RA and SGLT2i medications in combination compared with separate use in a real-world setting in a veteran population. The magnitude of change seen in this population appears greater compared with previous studies.

Limitations

There were several limitations to our study. Given the retrospective nature, many patients included in the study did not have bloodwork drawn during the specified time frames. Because of this, many patients were excluded and missing data on renal outcomes limited the power to detect differences. Data regarding AEs were limited to what was recorded in the EHR, which may underrepresent the AEs that patients experienced. Finally, our study size was small, consisting primarily of a White and male population, which may limit generalizability.

Further research is needed to validate these findings in this population and should include a larger study population. The impact of combining GLP-1 RA with SGLT2i on cardiorenal outcomes is an important area of ongoing research.

ConclusionS

The combined use of GLP-1 RA and SGLT2i resulted in significant improvement in HbA_1c levels, weight, and SBP compared with separate use in this real-world study of a VA population with T2DM. The combination was well tolerated overall. Awareness of these results can facilitate optimal care and outcomes in the VA population.

The DURATION 8 trial is the only double-blind trial to randomize subjects to receive either exenatide once weekly, dapagliflozin, or the combination of both for up to 52 weeks.³ Other controlled trials required stable background therapy with either SGLT2i or GLP-1 RA before randomization to receive the other class or placebo and had durations between 18 and 30 weeks.^4-7 The AWARD 10 trial studied the combination of canagliflozin and dulaglutide, which both have proven CVD benefit.⁴ Other studies did not restrict SGLT2i or GLP-1 RA background therapy to agents with proven CVD benefit.^5-7 The present study evaluated the combination of empagliflozin plus liraglutide or semaglutide, agents that all have proven CVD benefit.

A meta-analysis of 7 trials, including those previously mentioned, was conducted to evaluate the combination of GLP-1 RA and SGLT2i.⁸ The combination significantly reduced HbA_1c levels by 0.61% and 0.85% compared with GLP-1 RA or SGLT2i, respectively. Our trial showed greater HbA_1c level reduction of 1% with combination therapy compared with either agent separately. This may have been due in part to a higher baseline HbA_1c level in our real-world veteran population. The meta-analysis found the combination decreased body weight 2.6 kg and 1.5 kg compared with GLP-1 RA or SGLT2i, respectively.⁸ This only reached significance with comparison vs GLP-1 RA alone. Our study demonstrated impressive weight loss of up to about 5 kg after 26 and 52 weeks of combination therapy. This is equivalent to about 5% weight loss from baseline, which is clinically significant.⁹ Liraglutide and semaglutide are the GLP-1 RAs associated with the greatest weight loss, which may contribute to greater weight loss efficacy seen in the present trial.¹

In our trial SBP fell lower compared with the meta-analysis. Combination therapy significantly reduced SBP by 4.1 mm Hg and 2.7 mm Hg compared with GLP-1 RA or SGLT2i, respectively, in the meta-analysis.⁸ We observed a significant 9 to 12 mm Hg reduction in SBP after 26 to 52 weeks of combination therapy compared with baseline. This reduction occurred despite relatively controlled SBP at baseline (135 mm Hg). Each reduction of 10 mm Hg in SBP significantly reduces the risk of MACE, stroke, and heart failure, making our results clinically significant.¹⁰ Neither the meta-analysis nor present study found a significant difference in DBP or eGFR with combination therapy.

AEs were similar in this trial compared with the meta-analysis. Combination treatment with GLP-1 RA and SGLT2i did not increase the incidence of severe hypoglycemia in either study.⁸ Hypoglycemia was the most common AE in this study, but frequency was similar with combination and separate therapy. Both medication classes are associated with low or no risk of hypoglycemia on their own.¹ Baseline medications likely contributed to episodes of hypoglycemia seen in this study: About 80% of patients were prescribed basal insulin, 15% were prescribed a sulfonylurea, and 13% were prescribed prandial insulin. There is limited overlap between the known AEs of GLP-1 RA and SGLT2i, making combination therapy a safe option for use in patients with T2DM.

Our study confirms greater reduction in HbA_1c levels, weight, and SBP in veterans taking GLP-1 RA and SGLT2i medications in combination compared with separate use in a real-world setting in a veteran population. The magnitude of change seen in this population appears greater compared with previous studies.

Limitations

There were several limitations to our study. Given the retrospective nature, many patients included in the study did not have bloodwork drawn during the specified time frames. Because of this, many patients were excluded and missing data on renal outcomes limited the power to detect differences. Data regarding AEs were limited to what was recorded in the EHR, which may underrepresent the AEs that patients experienced. Finally, our study size was small, consisting primarily of a White and male population, which may limit generalizability.

Further research is needed to validate these findings in this population and should include a larger study population. The impact of combining GLP-1 RA with SGLT2i on cardiorenal outcomes is an important area of ongoing research.

ConclusionS

The combined use of GLP-1 RA and SGLT2i resulted in significant improvement in HbA_1c levels, weight, and SBP compared with separate use in this real-world study of a VA population with T2DM. The combination was well tolerated overall. Awareness of these results can facilitate optimal care and outcomes in the VA population.

Selecting the best medication regimen for a patient with type 2 diabetes mellitus (T2DM) depends on many factors, such as glycemic control, adherence, adverse effect (AE) profile, and comorbid conditions.¹ Selected agents from 2 newer medication classes, glucagon-like peptide 1 receptor agonists (GLP-1 RA) and sodium-glucose cotransporter 2 inhibitors (SGLT2i), have demonstrated cardiovascular and renal protective properties, creating a new paradigm in management.

The American Diabetes Association recommends medications with proven benefit in cardiovascular disease (CVD), such as the GLP-1 RAs liraglutide, injectable semaglutide, or dulaglutide, or the SGLT2i empagliflozin or canagliflozin, as second-line after metformin in patients with established atherosclerotic CVD or indicators of high risk to reduce the risk of major adverse cardiovascular events (MACE).¹ SGLT2i are preferred in patients with diabetic kidney disease, and GLP-1 RAs are next in line for selection of agents with proven nephroprotection (liraglutide, injectable semaglutide, dulaglutide). The mechanisms of these benefits are not fully understood but may be due to their extraglycemic effects. The classes likely induce these benefits by different mechanisms: SGLT2i by hemodynamic effects and GLP-1 RAs by anti-inflammatory mechanisms.² Although there is much interest, evidence is limited regarding the cardiovascular and renal protection benefits of these agents used in combination.

The combined use of GLP-1 RA and SGLT2i agents demonstrated greater benefit than separate use in trials with nonveteran populations.^3-7 These studies evaluated effects on hemoglobin A_1c (HbA_1c) levels, weight loss, blood pressure (BP), and estimated glomerular filtration rate (eGFR).A meta-analysis of 7 trials found that the combination of GLP-1 RA and SGLT2i reduced HbA_1c levels, body weight, and systolic blood pressure (SBP).⁸ All of the changes were statistically significant except for body weight with combination vs SGLT2i alone. Combination therapy was not associated with increased risk of severe hypoglycemia compared with either therapy separately.

The purpose of our study was to evaluate the safety and efficacy of the combined use of GLP-1 RA and SGLT2i in a real-world, US Department of Veterans Affairs (VA) population with T2DM.

Methods

This study was a pre-post, retrospective, single-center chart review. Subjects served as their own control. The project was reviewed and approved by the VA Ann Arbor Healthcare System Institutional Review Board. Subjects prescribed both a GLP-1 RA (semaglutide or liraglutide) and SGLT2i (empagliflozin) between January 1, 2014, and November 10, 2019, were extracted from the Corporate Data Warehouse (CDW) for possible inclusion in the study.

Patients were excluded if they received < 12 weeks of combination GLP-1 RA and SGLT2i therapy or did not have a corresponding 12-week HbA_1c level. Patients also were excluded if they had < 12 weeks of monotherapy before starting combination therapy or did not have a baseline HbA_1c level, or if the start date of combination therapy was not recorded in the VA electronic health record (EHR). We reviewed data for each patient from 6 months before to 1 year after the second agent was started. Start of the first agent (GLP-1 RA or SGLT2i) was recorded as the date the prescription was picked up in-person or 7 days after release date if mailed to the patient. Start of the second agent (GLP-1 RA or SGLT2i) was defined as baseline and was the date the prescription was picked up in person or 7 days after the release date if mailed.

Baseline measures were taken anytime from 8 weeks after the start of the first agent through 2 weeks after the start of the second agent. Data collected included age, sex, race, height, weight, BP, HbA_1c levels, serum creatinine (SCr), eGFR, classes of medications for the treatment of T2DM, and the number of prescribed antihypertensive medications. HbA_1c levels, SCr, eGFR, weight, and BP also were collected at 12 weeks (within 8-21 weeks); 26 weeks (within 22-35 weeks); and 52 weeks (within 36-57 weeks) of combination therapy. We reviewed progress notes and laboratory results to determine AEs within 26 weeks before initiating second agent (baseline) and 0 to 26 weeks and 26 to 52 weeks after initiating combination therapy.

The primary objective was to determine the effect on HbA_1c levels at 12 weeks when using a GLP-1 RA and SGLT2i in combination vs separately. Secondary objectives were to determine change from baseline in mean body weight, BP, SCr, and eGFR at 12, 26, and 52 weeks; change in HbA_1c levels at 26 and 52 weeks; and incidence of prespecified adverse drug reactions during combination therapy vs separately.

Statistical Analysis

Assuming a SD of 1, 80% power, significance level of P < .05, 2-sided test, and a correlation between baseline and follow-up of 0.5, we determined that a sample size of 34 subjects was required to detect a 0.5% change in baseline HbA_1c level at 12 weeks. A t test (or Wilcoxon signed rank test if outcome not normally distributed) was conducted to examine whether the expected change from baseline was different from 0 for continuous outcomes. Median change from baseline was reported for SCr as a nonparametric t test (Wilcoxon signed rank test) was used.

Results

We identified 110 patients for possible study inclusion and 39 met eligibility criteria. After record review, 30 patients were excluded for receiving < 12 weeks of combination therapy or no 12 week HbA_1c level; 26 patients were excluded for receiving < 12 weeks of monotherapy before starting combination therapy or no baseline HbA_1c level; and 15 patients were excluded for lack of documentation in the VA EHR. Of the 39 patients included, 24 (62%) were prescribed empagliflozin first and then 8 started liraglutide and 16 started semaglutide.

HbA_1c levels decreased by 1% after 12 weeks of combination therapy compared with baseline (P < .001), and this reduction was sustained through the duration of the study period (Table 2).

Discussion

This study evaluated the safety and efficacy of combined use of semaglutide or liraglutide and empagliflozin in a veteran population with T2DM. The retrospective chart review captured real-world practice and outcomes. Combination therapy was associated with a significant reduction in HbA_1c levels, body weight, and SBP compared with either agent alone. No significant change was seen in DBP, SCr, or eGFR. Overall, the combination of GLP-1 RA and SGLT2i medications demonstrated a good safety profile with most patients reporting no AEs.

Celiac disease is linked to juvenile idiopathic arthritis (JIA) in children and rheumatoid arthritis (RA) in adults, according to an analysis of nationwide data in Sweden.

Children with celiac disease are nearly three times as likely to develop JIA relative to the general population. Adults with celiac disease are nearly two times as likely to be diagnosed with RA.

“I hope that our study can ultimately change clinical practice by lowering the threshold to evaluate celiac disease patients for inflammatory joint diseases,” John B. Doyle, MD, a gastroenterology fellow at Columbia University Irving Medical Center in New York, told this news organization.

“Inflammatory joint diseases, such as JIA and RA, are notoriously difficult to diagnose given their variable presentations,” he said. “But if JIA or RA can be identified sooner by physicians, patients will ultimately benefit by starting disease-modifying therapy earlier in their disease course.”

The study was published online in The American Journal of Gastroenterology.
 

Analyzing associations

Celiac disease has been linked to numerous autoimmune diseases, including type 1 diabetes, autoimmune thyroid disease, lupus, and inflammatory bowel disease (IBD), Dr. Doyle noted. However, a definitive epidemiologic association between celiac disease and inflammatory joint diseases such as JIA or RA hasn›t been established.

Dr. Doyle and colleagues conducted a nationwide population-based, retrospective matched cohort study using the Epidemiology Strengthened by Histopathology Reports in Sweden. They identified 24,014 patients diagnosed with biopsy-proven celiac disease between 2004 and 2017.

With these data, each patient was matched to five reference individuals in the general population by age, sex, calendar year, and geographic region, for a total of 117,397 people without a previous diagnosis of celiac disease. The researchers calculated the incidence and estimated the relative risk for JIA in patients younger than 18 years and RA in patients aged 18 years or older.

For those younger than 18 years, the incidence rate of JIA was 5.9 per 10,000 person-years among the 9,415 patients with celiac disease versus 2.2 per 10,000 person-years in the general population, over a follow-up of 7 years. Those with celiac disease were 2.7 times as likely to develop JIA.

The association between celiac disease and JIA remained similar after adjustment for education, Nordic country of birth, type 1 diabetes, autoimmune thyroid disease, lupus, and IBD. The incidence rate of JIA among patients with celiac disease was higher in both females and males, and across all age groups studied.

When 6,703 children with celiac disease were compared with their 9,089 siblings without celiac disease, the higher risk for JIA in patients with celiac disease fell slightly short of statistical significance.

For those aged 18 years or older, the incidence rate of RA was 8.4 per 10,000 person-years among the 14,599 patients with celiac disease versus 5.1 per 10,000 person-years in the general population, over a follow-up of 8.8 years. Those with celiac disease were 1.7 times as likely to develop RA.

As with the younger cohort, the association between celiac disease and RA in the adult group remained similar after adjustment for education, Nordic country of birth, type 1 diabetes, autoimmune thyroid disease, lupus, and IBD. Although both men and women with celiac disease had higher rates of RA, the risk was higher among those in whom disease was diagnosed at age 18-59 years compared with those who received a diagnosis at age 60 years or older.

When 9,578 adults with celiac disease were compared with their 17,067 siblings without celiac disease, the risk for RA remained higher in patients with celiac disease.

This suggests “that the association between celiac disease and RA is unlikely to be explained by environmental factors alone,” Dr. Doyle said.
 

Additional findings

Notably, the primary analysis excluded patients diagnosed with JIA or RA before their celiac disease diagnosis. In additional analyses, however, significant associations emerged.

Among children with celiac disease, 0.5% had a previous diagnosis of JIA, compared with 0.1% of matched comparators. Those with celiac disease were 3.5 times more likely to have a JIA diagnosis.

Among adults with celiac disease, 0.9% had a previous diagnosis of RA, compared with 0.6% of matched comparators. Those with celiac disease were 1.4 times more likely to have a RA diagnosis.

“We found that diagnoses of these types of arthritis were more common before a diagnosis of celiac disease compared to the general population,” Benjamin Lebwohl, MD, director of clinical research at the Celiac Disease Center at Columbia University, New York, told this news organization.

“This suggests that undiagnosed and untreated celiac disease might be contributing to these others autoimmune conditions,” he said.

Dr. Doyle and Dr. Lebwohl emphasized the practical implications for clinicians caring for patients with celiac disease. Among patients with celiac disease and inflammatory joint symptoms, clinicians should have a low threshold to evaluate for JIA or RA, they said.

“Particularly in pediatrics, we are trained to screen patients with JIA for celiac disease, but this study points to the possible bidirectional association and the importance of maintaining a clinical suspicion for JIA and RA among established celiac disease patients,” Marisa Stahl, MD, assistant professor of pediatrics and associate program director of the pediatric gastroenterology, hepatology, and nutrition fellowship training program at the University of Colorado at Denver, Aurora, said in an interview.

Dr. Stahl, who wasn’t involved with this study, conducts research at the Colorado Center for Celiac Disease. She and colleagues are focused on understanding the genetic and environmental factors that lead to the development of celiac disease and other autoimmune diseases.

Given the clear association between celiac disease and other autoimmune diseases, Dr. Stahl agreed that clinicians should have a low threshold for screening, with “additional workup for other autoimmune diseases once an autoimmune diagnosis is established.”

The study was supported by Karolinska Institutet and the Swedish Research Council. Dr. Lebwohl coordinates a study on behalf of the Swedish IBD quality register, which has received funding from Janssen. The other authors declared no conflicts of interest. Dr. Stahl reported no relevant disclosures.

“Particularly in pediatrics, we are trained to screen patients with JIA for celiac disease, but this study points to the possible bidirectional association and the importance of maintaining a clinical suspicion for JIA and RA among established celiac disease patients,” Marisa Stahl, MD, assistant professor of pediatrics and associate program director of the pediatric gastroenterology, hepatology, and nutrition fellowship training program at the University of Colorado at Denver, Aurora, said in an interview.

Dr. Stahl, who wasn’t involved with this study, conducts research at the Colorado Center for Celiac Disease. She and colleagues are focused on understanding the genetic and environmental factors that lead to the development of celiac disease and other autoimmune diseases.

Given the clear association between celiac disease and other autoimmune diseases, Dr. Stahl agreed that clinicians should have a low threshold for screening, with “additional workup for other autoimmune diseases once an autoimmune diagnosis is established.”

The study was supported by Karolinska Institutet and the Swedish Research Council. Dr. Lebwohl coordinates a study on behalf of the Swedish IBD quality register, which has received funding from Janssen. The other authors declared no conflicts of interest. Dr. Stahl reported no relevant disclosures.

I never get sick. I’ve never had the flu. When everyone’s got a cold, I’m somehow immune. The last time I threw up was June 29th, 1980. You see, I work out almost daily, eat vegan, and sleep plenty. I drink gallons of pressed juice and throw down a few high-quality supplements. Yes, I’m that guy: The one who never gets sick. Well, I was anyway.

I am no longer that guy since our little girl became a supersocial little toddler. My undefeated welterweight “never-sick” title has been obliterated by multiple knockouts. One was a wicked adenovirus that broke the no-vomit streak. At one point, I lay on the luxury gray tile bathroom floor hoping to go unconscious to make the nausea stop. I actually called out sick that day. Then with a nasty COVID-despite-vaccine infection. I called out again. Later with a hacking lower respiratory – RSV?! – bug. Called out. All of which our 2-year-old blonde, curly-haired vector transmitted to me with remarkable efficiency.

In fact, we reached the high water mark for physicians calling out sick from my department this year. That’s saying a lot. Our docs, like most, don’t call out sick.

We physicians have legendary stamina. Compared with other professionals, we are no less likely to become ill but a whopping 80% less likely to call out sick.

Presenteeism is our physician version of Omerta, a code of honor to never give in even at the expense of our, or our family’s, health and well-being. Every medical student is regaled with stories of physicians getting an IV before rounds or finishing clinic after their water broke. Why? In part it’s an indoctrination into this thing of ours we call Medicine: An elitist club that admits only those able to pass O-chem and hold diarrhea. But it is also because our medical system is so brittle that the slightest bend causes it to shatter. When I cancel a clinic, patients who have waited weeks for their spot have to be sent home. And for critical cases or those patients who don’t get the message, my already slammed colleagues have to cram the unlucky ones in between already-scheduled appointments. The guilt induced by inconveniencing our colleagues and our patients is more potent than dry heaves. And so we go. Suck it up. Sip ginger ale. Load up on acetaminophen. Carry on. This harms not only us, but also patients whom we put in the path of transmission. We become terrible 2-year-olds.

Contact allergy to cobalt, chromium, and especially nickel, may be higher in European metalworkers than in all European male patients with allergic contact dermatitis, a systematic review and meta-analysis reports.

“Metal allergy to all three metals was significantly more common in European metalworkers with dermatitis attending patch test clinics as compared to ESSCA [European Surveillance System on Contact Allergies] data, indicating a relationship to occupational exposures,” senior study author Jeanne D. Johansen, MD, professor, department of dermatology and allergy, Copenhagen University Hospital, Hellerup, Denmark, and colleagues at the University of Copenhagen wrote in Contact Dermatitis. “However, confounders could not be accounted for.”

How common is metal allergy in metalworkers?

Occupational hand eczema is known to be common in metalworkers. Touching oils, greases, metals, leather gloves, rubber materials, and metalworking fluids as they repeatedly cut, shape, and process raw metals and minerals derived from ore mining exposes metalworkers to allergens and skin irritants, the authors wrote. But the prevalence of allergy to certain metals has not been well characterized.

So they searched PubMed for full-text studies in English that reported metal allergy prevalence in metalworkers, from the database’s inception through April 2022.

They included studies with absolute numbers or proportions of metal allergy to cobalt, chromium, or nickel, in all metalworkers with suspected allergic contact dermatitis who attended outpatient clinics or who worked at metalworking plants participating in workplace studies.

The researchers performed a random-effects meta-analysis to calculate the pooled prevalence of metal allergy. Because 85%-90% of metalworkers in Denmark are male, they compared the estimates they found with ESSCA data on 13,382 consecutively patch-tested males with dermatitis between 2015 and 2018.

Of the 1,667 records they screened, they analyzed data from 29 that met their inclusion criteria: 22 patient studies and 7 workplace studies involving 5,691 patients overall from 22 studies from Europe, 5 studies from Asia, and 1 from Africa. Regarding European metalworkers, the authors found:

• Pooled proportions of allergy in European metalworkers with dermatitis referred to patch test clinics were 8.2% to cobalt (95% confidence interval, 5.3%-11.7%), 8.0% to chromium (95% CI, 5.1%-11.4%), and 11.0% to nickel (95% CI, 7.3%-15.4%).
• In workplace studies, the pooled proportions of allergy in unselected European metalworkers were 4.9% to cobalt, (95% CI, 2.4%-8.1%), 5.2% to chromium (95% CI, 1.0% - 12.6%), and 7.6% to nickel (95% CI, 3.8%-12.6%).
• By comparison, ESSCA data on metal allergy prevalence showed 3.9% allergic to cobalt (95% CI, 3.6%-4.2%), 4.4% allergic to chromium (95% CI, 4.1%-4.8%), and 6.7% allergic to nickel (95% CI, 6.3%-7.0%).
• Data on sex, age, body piercings, and atopic dermatitis were scant.

Thorough histories, protective regulations and equipment

Providers need to ask their dermatitis patients about current and past occupations and hobbies, and employers need to provide employees with equipment that protects them from exposure, Kelly Tyler, MD, associate professor of dermatology, Ohio State University Wexner Medical Center, Columbus, said in an interview.

“Repeated exposure to an allergen is required for sensitization to develop,” said Dr. Tyler, who was not involved in the study. “Metalworkers, who are continually exposed to metals and metalworking fluids, have a higher risk of allergic contact dermatitis to cobalt, chromium, and nickel.”

“The primary treatment for allergic contact dermatitis is preventing continued exposure to the allergen,” she added. “This study highlights the importance of asking about metal or metalworking fluid in the workplace and of elucidating whether the employer is providing appropriate protective gear.”

To prevent occupational dermatitis, workplaces need to apply regulatory measures and provide their employees with protective equipment, Dr. Tyler advised.

“Body piercings are a common sensitizer in patients with metal allergy, and the prevalence of body piercings among metalworkers was not included in the study,” she noted.

The results of the study may not be generalizable to patients in the United States, she added, because regulations and requirements to provide protective gear here may differ.

“Taking a thorough patient history is crucial when investigating potential causes of dermatitis, especially in patients with suspected allergic contact dermatitis,” Dr. Tyler urged.

Funding and conflict-of-interest details were not provided. Dr. Tyler reported no relevant financial relationships.

CHICAGO – Clinicians who prescribe heart failure meds are holding the best hand they’ve ever had, but with so much underuse and suboptimal dosing in actual practice, it seems many may not appreciate the value of their cards. But a major randomized trial that has captured the field’s attention may embolden them to go all in.

Results showed that a strategy of early, rapid up-titration of multiple guideline-directed meds in patients hospitalized with heart failure, compared with a usual-care approach, cut their 6-month risk for death or HF readmission by a steep 34% (P = .002).

The drugs had been started and partly up-titrated in the hospital with the goal of full up-titration within 2 weeks after discharge.

Patients well tolerated the high-intensity approach, researchers said. Their quality-of-life scores improved (P < .0001) compared with the usual-care group, and adverse events were considered few and manageable in the international trial with more than 1,000 patients.

Safety on the high-intensity strategy depended on close patient monitoring at frequently planned clinic visits along with guidance for the up-titrations from clinical signs and natriuretic peptide levels, observed Alexandre Mebazaa, MD, PhD, University of Paris and Public Hospitals of Paris.

Dr. Mebazaa is principal investigator on the trial, called STRONG-HF, which he presented at the American Heart Association scientific sessions, held in Chicago and virtually. He is also lead author on the study’s same-day publication in the Lancet.

The high-intensity strategy’s superiority emerged early in the trial, which was halted early on the data safety monitoring board’s recommendation, with about 90% of follow-ups completed. The board “felt it was unethical to keep patients in usual care,” Dr. Mebazaa said at a press conference.
 

A dramatic change

The next step, he said, will be to educate the heart failure community on the high-intensity care technique so it can swiftly enter clinical practice. Currently in acute heart failure, “very few patients are monitored after discharge and treated with full doses of heart failure therapies.”

Adoption of the strategy “would be a dramatic change from what’s currently being done,” said Martin B. Leon, MD, NewYork-Presbyterian/Columbia University Irving Medical Center, New York, who moderated the press conference.

Only an estimated 5% of patients with HF in the United States receive full guideline-directed medical therapy, Dr. Leon said, “so the generalizability of this strategy, with careful follow-up that has safety involved in it, is absolutely crucial.”

But the potential impact of this high-intensity approach on resource use is unknown, raising questions about how widely and consistently it could be implemented, said Dr. Leon, who is not connected with STRONG-HF.

The trial called for in-hospital initiation of the three distinct drug classes that, at the time, were the core of guideline-directed HF therapy, with up-titration to 50% of recommended dosage by hospital discharge, and then to 100% within 2 weeks later.

The meds included a beta-blocker, a mineralocorticoid receptor antagonist (MRA), and a renin-angiotensin system inhibitor (RASI). The latter could be an ACE inhibitor, angiotensin-receptor blocker (ARB), or angiotensin receptor-neprilysin inhibitor (ARNI).
 

How about a fourth drug?

Conspicuously absent from the list, for contemporary practice, was an SGLT2 inhibitor, a class that entered the HF guidelines well after STRONG-HF was designed. They would undoubtedly join the other three agents were the high-intensity strategy to enter practice, potentially changing its complexity and safety profile.

But Dr. Mebazaa and other experts don’t see that as a big challenge and would expect a smooth transition to a high-intensity approach that also includes the SGLT2 inhibitors.

STRONG-HF was necessary in part because many clinicians have been “reluctant” to take full advantage of three agents that had been the basis of guideline-directed therapy, he told this news organization.

That reluctance stemmed from concerns that beta-blockers might worsen the heart failure, ACE inhibitors could hurt the kidneys, or MRAs might cause hyperkalemia, Dr. Mebazaa said. The STRONG-HF high-intensity regimen, therefore, demanded multiple clinic visits for close follow-up.

But the SGLT2 inhibitors “are known to be rather safe drugs, at least much safer than the three others,” he said. So, it seems unlikely that their addition to a beta-blocker, RASI, and MRA in patients with HF would worsen the risk of adverse events.

John G.F. Cleland, MD, PhD, agrees. With addition of the fourth agent, “You may need to be a little bit more careful with renal function, just in that first couple of weeks,” he told this news organization. “But I think it would be easy to add an SGLT2 inhibitor into this regimen. And in general, there’s no titration with an SGLT2 inhibitor, so they’ll all be on full dose predischarge.”

Given the drugs’ diuretic-like action, moreover, some patients might be able to pull back on their loop diuretics, speculated Dr. Cleland, from the University of Glasgow’s School of Health and Wellbeing.

The prospect of a high-intensity strategy’s wide implementation in practice presents both “challenges and opportunities,” Amanda R. Vest, MBBS, MPH, Tufts University, Boston, told this news organization.

“There may be additional challenges in terms of ensuring we avoid hypotension or acute kidney injury in the up-titration phase,” said Dr. Vest, who is medical director of her center’s cardiac transplantation program but not connected with STRONG-HF.

“But it also gives us opportunities,” she added, “because there are some patients, especially in that vulnerable postdischarge phase, who are actually much more able to tolerate introduction of an SGLT2 inhibitor than, for example, an ACE inhibitor, ARB, or ARNI – or maybe a beta-blocker if they’ve been in a low cardiac-output state.” Effective dosing would depend on “the personalization and skill of the clinician in optimizing the medications in their correct sequence,” Dr. Vest said.

“It’s challenging to think that we would ever get to 100% up-titration,” she added, “and even in this excellent study, they didn’t get to 100%.” But as clinicians gain experience with the high-intensity strategy, especially as the SGLT2 inhibitors are included, “I think we can reasonably expect more progress to be made in these up-titration skills.”
 

No restrictions on LVEF

The researchers entered 1,078 patients hospitalized with acute HF in 14 countries across Africa, Europe, the Middle East, and South America, and randomly assigned them to the high-intensity management strategy or usual care.

About 60% of the patients were male and 77% were White. There were no entry restrictions based on left ventricular ejection fraction (LVEF), which exceeded 40% in almost a third of cases.

In the high-intensity care group’s 542 patients, the three agents were up-titrated to 50% of the maximum guideline-recommended dosage prior to hospital discharge, and to 100% within 2 weeks after discharge. Symptoms and laboratory biomarkers, including natriuretic peptides, were monitored closely at four planned clinical visits over the following 6 weeks.

The 536 patients assigned to usual care were discharged and managed according to local standards, with their meds handled by their own primary care doctors or cardiologists, the published report notes. They were reevaluated by STRONG-HF clinicians 90 days after discharge.

The number of clinic visits in the first 90 postdischarge days averaged 4.8 in the high-intensity care group and 1.0 for those receiving usual care. Full up-titration was far more likely in the high-intensity care group: 55% vs. 2% for RASI agents, 49% vs. 4% for beta-blockers, and 84% vs. 46% for MRAs.

They also fared significantly better on all measured parameters associated with decongestion, including weight, prevalence of peripheral edema, jugular venous pressure, NYHA functional class, and natriuretic peptide levels, the researchers said.

The primary endpoint of 180-day death from any cause or HF readmission was met by 15.2% of the high-intensity care group and 23.3% of usual-care patients, for an adjusted risk ratio (RR) of 0.66 (95% CI, 0.50-0.86; P = .0021).

Subgroup analyses saw no significant interactions by age, sex, race, geography, or baseline blood pressure, renal function, or LVEF. Patients with higher vs. lower baseline natriuretic peptide levels trend toward better responses to high-intensity care (P = .08)
 

The COVID effect

The group performed a sensitivity analysis that excluded deaths attributed to COVID-19 in STRONG-HF, which launched prior to the pandemic. The high-intensity strategy’s benefit for the primary endpoint grew, with an adjusted RR of 0.61 (95% CI, 0.46-0.82; P = .0005). There was no corresponding effect on death from any cause (P = .15).

Treatment-related adverse effects in the overall trial were seen in 41.1% of the high-intensity care group and in 29.5% of those assigned to usual care.

The higher rate in the high-intensity care arm “may be related to their higher number of [clinic] visits compared to usual care,” Dr. Mebazaa said. “However, serious adverse events and fatal adverse events were similar in both arms.”

Cardiac failure was the most common adverse event, developing in about 15% in both groups. It was followed by hypotension, hyperkalemia, and renal impairment, according to the published report.

Dr. Cleland cautioned that the risk of adverse events would potentially be higher should the high-intensity strategy become common clinical practice. The median age in STRONG-HF was 63, which is “10-15 years younger, on average, than the population with recently admitted heart failure that we see. There’s no doubt that older people have more multimorbidity.”

STRONG-HF was funded by Roche Diagnostics. Dr. Mebazaa discloses receiving grants from Roche Diagnostics, Abbott Laboratories, 4TEEN4, and Windtree Therapeutics; honoraria for lectures from Roche Diagnostics, Bayer, and Merck, Sharp & Dohme; and consulting for Corteria Pharmaceuticals, S-form Pharma, FIRE-1, Implicity, 4TEEN4, and Adrenomed; and to being a co-inventor on a patent involving combination therapy for patients having acute or persistent dyspnea.

Dr. Vest reports modest relationships with Boehringer Ingelheim, Corvia, and CareDx; and receiving research grants from the American Heart Association and the National Institutes of Health.

CHICAGO – Clinicians who prescribe heart failure meds are holding the best hand they’ve ever had, but with so much underuse and suboptimal dosing in actual practice, it seems many may not appreciate the value of their cards. But a major randomized trial that has captured the field’s attention may embolden them to go all in.

Results showed that a strategy of early, rapid up-titration of multiple guideline-directed meds in patients hospitalized with heart failure, compared with a usual-care approach, cut their 6-month risk for death or HF readmission by a steep 34% (P = .002).

The drugs had been started and partly up-titrated in the hospital with the goal of full up-titration within 2 weeks after discharge.

Patients well tolerated the high-intensity approach, researchers said. Their quality-of-life scores improved (P < .0001) compared with the usual-care group, and adverse events were considered few and manageable in the international trial with more than 1,000 patients.

Safety on the high-intensity strategy depended on close patient monitoring at frequently planned clinic visits along with guidance for the up-titrations from clinical signs and natriuretic peptide levels, observed Alexandre Mebazaa, MD, PhD, University of Paris and Public Hospitals of Paris.

Dr. Mebazaa is principal investigator on the trial, called STRONG-HF, which he presented at the American Heart Association scientific sessions, held in Chicago and virtually. He is also lead author on the study’s same-day publication in the Lancet.

The high-intensity strategy’s superiority emerged early in the trial, which was halted early on the data safety monitoring board’s recommendation, with about 90% of follow-ups completed. The board “felt it was unethical to keep patients in usual care,” Dr. Mebazaa said at a press conference.
 

A dramatic change

The next step, he said, will be to educate the heart failure community on the high-intensity care technique so it can swiftly enter clinical practice. Currently in acute heart failure, “very few patients are monitored after discharge and treated with full doses of heart failure therapies.”

Adoption of the strategy “would be a dramatic change from what’s currently being done,” said Martin B. Leon, MD, NewYork-Presbyterian/Columbia University Irving Medical Center, New York, who moderated the press conference.

Only an estimated 5% of patients with HF in the United States receive full guideline-directed medical therapy, Dr. Leon said, “so the generalizability of this strategy, with careful follow-up that has safety involved in it, is absolutely crucial.”

But the potential impact of this high-intensity approach on resource use is unknown, raising questions about how widely and consistently it could be implemented, said Dr. Leon, who is not connected with STRONG-HF.

The trial called for in-hospital initiation of the three distinct drug classes that, at the time, were the core of guideline-directed HF therapy, with up-titration to 50% of recommended dosage by hospital discharge, and then to 100% within 2 weeks later.

The meds included a beta-blocker, a mineralocorticoid receptor antagonist (MRA), and a renin-angiotensin system inhibitor (RASI). The latter could be an ACE inhibitor, angiotensin-receptor blocker (ARB), or angiotensin receptor-neprilysin inhibitor (ARNI).
 

How about a fourth drug?

Conspicuously absent from the list, for contemporary practice, was an SGLT2 inhibitor, a class that entered the HF guidelines well after STRONG-HF was designed. They would undoubtedly join the other three agents were the high-intensity strategy to enter practice, potentially changing its complexity and safety profile.

But Dr. Mebazaa and other experts don’t see that as a big challenge and would expect a smooth transition to a high-intensity approach that also includes the SGLT2 inhibitors.

STRONG-HF was necessary in part because many clinicians have been “reluctant” to take full advantage of three agents that had been the basis of guideline-directed therapy, he told this news organization.

That reluctance stemmed from concerns that beta-blockers might worsen the heart failure, ACE inhibitors could hurt the kidneys, or MRAs might cause hyperkalemia, Dr. Mebazaa said. The STRONG-HF high-intensity regimen, therefore, demanded multiple clinic visits for close follow-up.

But the SGLT2 inhibitors “are known to be rather safe drugs, at least much safer than the three others,” he said. So, it seems unlikely that their addition to a beta-blocker, RASI, and MRA in patients with HF would worsen the risk of adverse events.

John G.F. Cleland, MD, PhD, agrees. With addition of the fourth agent, “You may need to be a little bit more careful with renal function, just in that first couple of weeks,” he told this news organization. “But I think it would be easy to add an SGLT2 inhibitor into this regimen. And in general, there’s no titration with an SGLT2 inhibitor, so they’ll all be on full dose predischarge.”

Given the drugs’ diuretic-like action, moreover, some patients might be able to pull back on their loop diuretics, speculated Dr. Cleland, from the University of Glasgow’s School of Health and Wellbeing.

The prospect of a high-intensity strategy’s wide implementation in practice presents both “challenges and opportunities,” Amanda R. Vest, MBBS, MPH, Tufts University, Boston, told this news organization.

“There may be additional challenges in terms of ensuring we avoid hypotension or acute kidney injury in the up-titration phase,” said Dr. Vest, who is medical director of her center’s cardiac transplantation program but not connected with STRONG-HF.

“But it also gives us opportunities,” she added, “because there are some patients, especially in that vulnerable postdischarge phase, who are actually much more able to tolerate introduction of an SGLT2 inhibitor than, for example, an ACE inhibitor, ARB, or ARNI – or maybe a beta-blocker if they’ve been in a low cardiac-output state.” Effective dosing would depend on “the personalization and skill of the clinician in optimizing the medications in their correct sequence,” Dr. Vest said.

“It’s challenging to think that we would ever get to 100% up-titration,” she added, “and even in this excellent study, they didn’t get to 100%.” But as clinicians gain experience with the high-intensity strategy, especially as the SGLT2 inhibitors are included, “I think we can reasonably expect more progress to be made in these up-titration skills.”
 

No restrictions on LVEF

The researchers entered 1,078 patients hospitalized with acute HF in 14 countries across Africa, Europe, the Middle East, and South America, and randomly assigned them to the high-intensity management strategy or usual care.

About 60% of the patients were male and 77% were White. There were no entry restrictions based on left ventricular ejection fraction (LVEF), which exceeded 40% in almost a third of cases.

In the high-intensity care group’s 542 patients, the three agents were up-titrated to 50% of the maximum guideline-recommended dosage prior to hospital discharge, and to 100% within 2 weeks after discharge. Symptoms and laboratory biomarkers, including natriuretic peptides, were monitored closely at four planned clinical visits over the following 6 weeks.

The 536 patients assigned to usual care were discharged and managed according to local standards, with their meds handled by their own primary care doctors or cardiologists, the published report notes. They were reevaluated by STRONG-HF clinicians 90 days after discharge.

The number of clinic visits in the first 90 postdischarge days averaged 4.8 in the high-intensity care group and 1.0 for those receiving usual care. Full up-titration was far more likely in the high-intensity care group: 55% vs. 2% for RASI agents, 49% vs. 4% for beta-blockers, and 84% vs. 46% for MRAs.

They also fared significantly better on all measured parameters associated with decongestion, including weight, prevalence of peripheral edema, jugular venous pressure, NYHA functional class, and natriuretic peptide levels, the researchers said.

The primary endpoint of 180-day death from any cause or HF readmission was met by 15.2% of the high-intensity care group and 23.3% of usual-care patients, for an adjusted risk ratio (RR) of 0.66 (95% CI, 0.50-0.86; P = .0021).

Subgroup analyses saw no significant interactions by age, sex, race, geography, or baseline blood pressure, renal function, or LVEF. Patients with higher vs. lower baseline natriuretic peptide levels trend toward better responses to high-intensity care (P = .08)
 

The COVID effect

The group performed a sensitivity analysis that excluded deaths attributed to COVID-19 in STRONG-HF, which launched prior to the pandemic. The high-intensity strategy’s benefit for the primary endpoint grew, with an adjusted RR of 0.61 (95% CI, 0.46-0.82; P = .0005). There was no corresponding effect on death from any cause (P = .15).

Treatment-related adverse effects in the overall trial were seen in 41.1% of the high-intensity care group and in 29.5% of those assigned to usual care.

The higher rate in the high-intensity care arm “may be related to their higher number of [clinic] visits compared to usual care,” Dr. Mebazaa said. “However, serious adverse events and fatal adverse events were similar in both arms.”

Cardiac failure was the most common adverse event, developing in about 15% in both groups. It was followed by hypotension, hyperkalemia, and renal impairment, according to the published report.

Dr. Cleland cautioned that the risk of adverse events would potentially be higher should the high-intensity strategy become common clinical practice. The median age in STRONG-HF was 63, which is “10-15 years younger, on average, than the population with recently admitted heart failure that we see. There’s no doubt that older people have more multimorbidity.”

STRONG-HF was funded by Roche Diagnostics. Dr. Mebazaa discloses receiving grants from Roche Diagnostics, Abbott Laboratories, 4TEEN4, and Windtree Therapeutics; honoraria for lectures from Roche Diagnostics, Bayer, and Merck, Sharp & Dohme; and consulting for Corteria Pharmaceuticals, S-form Pharma, FIRE-1, Implicity, 4TEEN4, and Adrenomed; and to being a co-inventor on a patent involving combination therapy for patients having acute or persistent dyspnea.

Dr. Vest reports modest relationships with Boehringer Ingelheim, Corvia, and CareDx; and receiving research grants from the American Heart Association and the National Institutes of Health. Dr. Cleland discloses receiving honoraria from Idorsia; and research grants from Vifor Pharma, Medtronic, Bayer, and Bristol-Myers Squibb. Dr. Leon had no disclosures.

Electrolyte abnormalities may serve as a precursor to a future eating disorder diagnosis, a finding that may help pinpoint candidates for screening.

Researchers found that adolescents and adults with electrolyte abnormalities on routine outpatient lab work were twice as likely as those without these disturbances to be subsequently diagnosed with an eating disorder.

“These electrolyte abnormalities were in fact seen well ahead (> 1 year on average) of the time when patients were diagnosed with eating disorders,” study investigator Gregory Hundemer, MD, department of nephrology, University of Ottawa, told this news organization.

“Incidentally discovered outpatient electrolyte abnormalities may help to identify individuals who may benefit from more targeted screening into an underlying eating disorder. This, in turn, may allow for earlier diagnosis and therapeutic intervention,” Dr. Hundemer said.

The study was published online in JAMA Network Open.
 

Tailored screening?

Electrolyte abnormalities are often found when an individual is diagnosed with an eating disorder, but it’s largely unknown whether electrolyte abnormalities prior to the acute presentation of an eating disorder are associated with the future diagnosis of an eating disorder.

To investigate, the researchers used administrative health data to match 6,970 individuals (mean age, 28 years; 13% male) with an eating disorder diagnosis to 27,878 controls without an eating disorder diagnosis.

They found that individuals with an eating disorder were more likely to have a preceding electrolyte abnormality, compared with peers without an eating disorder (18.4% vs. 7.5%).

An outpatient electrolyte abnormality present 3 years to 30 days prior to diagnosis was associated with about a twofold higher odds for subsequent eating disorder diagnosis (adjusted odds ratio, 2.12; 95% confidence interval, 1.86-2.41).

The median time from the earliest electrolyte abnormality to eating disorder diagnosis was 386 days (range, 157-716 days).

Hypokalemia was the most common electrolyte abnormality (present in 12% of cases vs. 5% of controls), while hyponatremia, hypernatremia, hypophosphatemia, and metabolic alkalosis were the most specific for a subsequent eating disorder diagnosis.

Severe hypokalemia (serum potassium levels of 3.0 mmol/L or lower) and severe hyponatremia (serum sodium, 128 mmol/L or lower) were associated with over sevenfold and fivefold higher odds for the diagnosis of an eating disorder, respectively.

The U.S. Preventive Services Task Force issued its first-ever statement on screening for eating disorders earlier this year.

The task force concluded that there is insufficient evidence to weigh the balance of benefits and harms of screening for eating disorders in adolescents and adults with no signs or symptoms of an eating disorder or concerns about their eating and who have not previously been diagnosed with an eating disorder.

Dr. Hundemer and colleagues believe an incidental electrolyte abnormality may identify candidates at high risk for an underlying eating disorder who many benefit from screening.

Several screening tools of varying complexity have been developed that are validated and accurate in identifying individuals with a potential eating disorder.

They include the SCOFF questionnaire, the Eating Disorder Screen for Primary Care, the Eating Attitudes Test, and the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire.
 

Underdiagnosed, undertreated

Offering perspective on the findings, Kamryn T. Eddy, PhD, codirector, Eating Disorders Clinical and Research Program, Massachusetts General Hospital, Boston, said the notion “that a physical sign may help to promote eating disorder assessment is important particularly given that early detection can improve outcomes.”

“But this finding appears in the current context of eating disorders going largely underdetected, underdiagnosed, and undertreated across medical and psychiatric settings,” said Dr. Eddy, associate professor, department of psychiatry, Harvard Medical School, Boston.

“Indeed, eating disorders are prevalent and cut across age, sex, gender, weight, race, ethnicity, and socioeconomic strata, and still, many providers do not routinely assess for eating disorders,” Dr. Eddy said.

“I might suggest that perhaps in addition to letting electrolyte abnormalities be a cue to screen for eating disorders, an even more powerful shift toward routine screening and assessment of eating disorders by medical providers be made,” Dr. Eddy said in an interview.

This study was supported by ICES, which is funded by an annual grant from the Ontario Ministry of Health and the Ministry of Health and Long-Term Care. Dr. Hundemer and Dr. Eddy have disclosed no relevant financial relationships.

The risk of stroke was about 23% lower in the 6 months following a flu shot, regardless of the patient’s age, sex, or underlying health conditions.

“There is an established link between upper respiratory infection and both heart attack and stroke. This has been very salient in the past few years throughout the COVID-19 pandemic,” study author Jessalyn Holodinsky, PhD, a stroke epidemiologist and postdoctoral fellow in clinical neurosciences at the University of Calgary (Alta.) told this news organization.

“It is also known that the flu shot can reduce risk of heart attack and hospitalization for those with heart disease,” she said. “Given both of these [observations], we thought it prudent to study whether there is a link between vaccination for influenza and stroke.”

The study was published in the Lancet Public Health.
 

Large effect size

The investigators analyzed administrative data from 2009 through 2018 from the Alberta Health Care Insurance Plan, which covers all residents of Alberta. The province provides free seasonal influenza vaccines to residents under the insurance plan.

The research team looked for stroke events such as acute ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage, and transient ischemic attack. They then analyzed the risk of stroke events among those with or without a flu shot in the previous 6 months. They accounted for multiple factors, including age, sex, income, location, and factors related to stroke risk, such as anticoagulant use, atrial fibrillation, chronic obstructive pulmonary disease, diabetes, and hypertension.

Among the 4.1 million adults included in the researchers’ analysis, about 1.8 million (43%) received at least one vaccination during the study period. Nearly 97,000 people received a flu vaccine in each year they were in the study, including 29,288 who received a shot in all 10 flu seasons included in the study.

About 38,000 stroke events were recorded, including about 34,000 (90%) first stroke events. Among the 10% of strokes that were recurrent events, the maximum number of stroke events in one person was nine.

Overall, patients who received at least one influenza vaccine were more likely to be older, be women, and have higher rates of comorbidities. The vaccinated group had a slightly higher proportion of people who lived in urban areas, but the income levels were similar between the vaccinated and unvaccinated groups.

The crude incidence of stroke was higher among people who had ever received an influenza vaccination, at 1.25%, compared with 0.52% among those who hadn’t been vaccinated. However, after adjusting for age, sex, underlying conditions, and socioeconomic status, recent flu vaccination (that is, in the previous 6 months) was associated with a 23% reduced risk of stroke.

The significant reduction in risk applied to all stroke types, particularly acute ischemic stroke and intracerebral hemorrhage. In addition, influenza vaccination was associated with a reduced risk across all ages and risk profiles, except patients without hypertension.

“What we were most surprised by was the sheer magnitude of the effect and that it existed across different adult age groups, for both sexes, and for those with and without risk factors for stroke,” said Dr. Holodinsky.

Vaccination was associated with a larger reduction in stroke risk in men than in women, perhaps because unvaccinated men had a significantly higher baseline risk for stroke than unvaccinated women, the study authors write.
 

Promoting cardiovascular health

In addition, vaccination was associated with a greater relative reduction in stroke risk in younger age groups, lower income groups, and those with diabetes, chronic obstructive pulmonary disease, and anticoagulant use.

Among 2.4 million people observed for the entire study period, vaccination protection increased with the number of vaccines received. People who were vaccinated serially each year had a significantly lower risk of stroke than those who received one shot.

Dr. Holodinsky and colleagues are conducting additional research into influenza vaccination, including stroke risk in children. They’re also investigating whether the reduced risk applies to other vaccinations for respiratory illnesses, such as COVID-19 and pneumonia.

“We hope that this added effect of vaccination encourages more adults to receive the flu shot,” she said. “One day, vaccinations might be considered a key pillar of cardiovascular health, along with diet, exercise, control of hypertension and high cholesterol, and smoking cessation.”

Future research should also investigate the reasons why adults – particularly people at high risk with underlying conditions – don’t receive recommended influenza vaccines, the study authors wrote.
 

‘Call to action’

Bahar Behrouzi, an MD-PhD candidate focused on clinical epidemiology at the Institute of Health Policy, Management, and Evaluation, University of Toronto, said: “There are a variety of observational studies around the world that show that flu vaccine uptake is low among the general population and high-risk persons. In studying these questions, our hope is that we can continue to build confidence in viral respiratory vaccines like the influenza vaccine by continuing to generate rigorous evidence with the latest data.”

Ms. Behrouzi, who wasn’t involved with this study, has researched influenza vaccination and cardiovascular risk. She and her colleagues have found that flu vaccines were associated with a 34% lower risk of major adverse cardiovascular events, including a 45% reduced risk among patients with recent acute coronary syndrome.

“The broader public health message is for people to advocate for themselves and get the seasonal flu vaccine, especially if they are part of an at-risk group,” she said. “In our studies, we have positioned this message as a call to action not only for the public, but also for health care professionals – particularly specialists such as cardiologists or neurologists – to encourage or remind them to engage in conversation about the broad benefits of vaccination beyond just preventing or reducing the severity of flu infection.”

The study was conducted without outside funding. Dr. Holodinsky and Ms. Behrouzi have reported no relevant disclosures.
