The explosion of interest in glucagon-like peptide 1 receptor agonists (GLP-1 RAs), such as semaglutide and tirzepatide, has raised questions about what therapeutic effects this class of medication might have beyond their current indications for type 2 diabetes and obesity. 

Recent clinical trials have recently identified benefits from GLP-1 agents for the heart, liver, and kidneys, but the current evidence base is murkier regarding how the drugs may affect male fertility. 

Experts say the connection between GLP-1 RAs and improved male fertility makes sense biologically. For starters, overweight and obesity are strongly associated with male infertility in several overlapping ways. Obesity can disrupt hormones linked to fertility, increase the risk for defective sperm, adversely affect semen quality, and even make sexual intercourse more difficult due to obesity’s link to erectile dysfunction. As a result, GLP-1 RAs should at least in theory boost male fertility in men who take the drugs to lose weight. 

But animal studies and a handful of small trials and observational data point to the potential for GLP-1 RAs to improve male fertility in other ways.

A recent narrative review on GLP-1 RAs and male reproductive health, published in the journal Medicina in December 2023, surveyed the potential of the drugs for male infertility and offered reason for optimism. 

Hossein Sadeghi-Nejad, MD, director of urology at NYU Langone Health, New York, and a coauthor of the article, said that one reason he and his colleagues conducted their analysis was the known association between weight loss and an increase in testosterone.

“Most of the animal studies that are out there show that this class of drugs does affect testosterone levels,” Dr. Sadeghi-Nejad said; they wanted to better understand what other evidence showed about GLP-1 agonists and other fertility factors. 
 

Link Between Obesity and Fertility

The recent paper first reviews the well-established link between obesity and poorer fertility outcomes. 

“Certainly, obesity poses a significant societal problem with substantial impacts on both overall health and economic aspects,” senior author Ranjith Ramasamy, MD, associate professor of urology and director of the reproductive urology Fellowship program at the University of Miami’s Miller School of Medicine, told this news organization. “The escalating global obesity rates raise concerns, especially in the field of male infertility, where excessive body fat induces intrinsic hormonal changes leading to alterations, eventually, in semen parameters.”

The authors noted that obesity has been linked in the research to worse assisted reproductive technology (ART) outcomes and to subfecundity, taking more than 12 months to achieve pregnancy. They also referenced a systematic review that found men with obesity were more likely to have lower sperm counts and less viable sperm.

“From our standpoint, I think the key point was to raise awareness about the fact that obesity, because of the aromatization of testosterone to estradiol [from excess adipose tissue], will affect the hormonal axis and the availability of testosterone and, therefore, indirectly affects spermatogenesis,” Dr. Sadeghi-Nejad said. 

Obesity is also linked to lower levels of inhibin B, which stimulates testosterone secretion in Sertoli cells, which, when combined with the proinflammatory state of obesity, “results in a less favorable environment for sperm production,” he said. Finally, the link between obesity and poorer sexual function further inhibits fertility potential, he added. 

Until recently, the primary treatments for obesity in men experiencing fertility problems have been lifestyle modifications or surgical interventions. But the recent approval of GLP-1 RA drugs for obesity present an additional option depending on how these drugs affect other fertility parameters. 
 

Direct or Indirect Effects?

Most of the available evidence on GLP-RAs and sperm parameters comes from preclinical research. One of the few clinical trials, published last year in the Journal of Clinical Medicine, investigated the effects of liraglutide in men with metabolic hypogonadism, a body mass index between (BMI) 30 and 40, and severe erectile dysfunction. 

Among the 110 men enrolled in the study, only the 35 participants who said that they were not seeking fatherhood received liraglutide. After 4 months of treatment, these men had significantly improved semen concentration, motility, and morphology than did those wanting to conceive who received conventional fertility treatment. Erectile dysfunction was also more improved in the liraglutide group, according to the researchers. 

Though this study demonstrated the potential for liraglutide to treat metabolic hypogonadism, the men in that group also had greater weight loss and BMI reduction than the other participants. The review cited several other studies — albeit small ones — in which weight loss was associated with improvements in sperm parameters, including one randomized controlled trial in which one group lost weight with liraglutide and the other with lifestyle modifications; both groups showed increases in the concentration and number of sperm. 

One of the key questions requiring further research, then, is whether GLP-1 agents have direct effects on male fertility independent of a reduction in obesity. The randomized controlled trials comparing liraglutide and lifestyle modifications failed to find additional effects on semen in the men taking liraglutide; however, the study had only 56 participants, and results from liraglutide cannot be generalized to potential effects of semaglutide or tirzepatide, Dr. Sadeghi-Nejad said.

“Determining the relative contributions of weight loss versus direct drug actions on fertility outcomes remains challenging without robust data,” Dr. Ramasamy said. “While acknowledged that diet and physical activity positively impact fertility, confirming the synergistic role of GLP-1 receptor agonists requires evidence from well-designed randomized clinical trials.” 

Rodent studies suggest that GLP-1 RAs may independently affect testicular function because GLP-1 receptors exist in Sertoli and Leydig cells of the testes. In one study, for example, obese mice who received the GLP-1 agonist exenatide for 8 weeks had “improved sperm motility, DNA integrity, and decreased expression of pro-inflammatory cytokines,” the authors of the review reported. But the precise mechanisms aren’t well understood. 

“We know that there are GLP-1 receptors in the reproductive tract, but the extent of the downstream effect of stimulating those receptors, I don’t think we know well,” said John P. Lindsey II, MD, MEng, assistant professor of urology at University of California San Francisco Health. 

Other hormonal effects of GLP-1 agonists, such as stimulating insulin production and better regulating blood glucose levels, are better understood, said Raevti Bole, MD, a urologist at Cleveland Clinic, in Ohio, but still other effects of the drugs may not yet be identified.

“I think the really big unknown is whether these types of drugs have effects that are not hormonal on male fertility and what those effects are, and how those affect sperm,” Dr. Bole said. “For example, we know that these drugs slow gastric emptying. Is it possible that slow gastric emptying affects some of the nutrients that you absorb, and that could affect fertility?” Similarly, she said, it’s not clear whether GLP-1 agonists would have any effects on the thyroid that could then affect fertility. 
 

Effects on Offspring

Another open question about GLP-1 RAs and male fertility is their potential effects on the offspring, said Sriram Machineni, MBBS, associate professor of endocrinology at the Albert Einstein College of Medicine in New York City. The clinical trials involving the drugs for treating type 2 diabetes and obesity required both men and women to use contraception. If sperm contributing to a pregnancy are exposed to a GLP-1 agent, “we don’t know what the consequences could be,” Dr. Machineni said. “Just increasing the fertility of the man is not enough. We need to make sure it’s safe long-term for the fetus.”

Dr. Bole also pointed out the need for understanding potential effects in the fetus.

“We know that there are epigenetic changes that can happen to sperm that are influenced by the lifestyle and the physical health and environment of the parent,” Dr. Bole said. “So how could these drugs potentially affect those epigenetic changes that then potentially are passed on to the offspring? We don’t know that.” 

An ideal source for that data would be a cohort registry of people who are taking the medication and then cause a pregnancy. “They have a registry for pregnant women,” Dr. Machineni said, “but we need something similar for men.”

Dr. Sadeghi-Nejad said that he and his coauthors are working on developing a registry for men who take GLP-1 RAs that would enable long-term tracking of multiple andrologic outcomes, including fertility and sexual dysfunction. Such a registry could theoretically be useful in tracking pregnancy and offspring outcomes as well. 
 

Too Soon for Prescribing

Additional options for treating fertility in men with obesity would be welcome. Current treatments include the selective estrogen receptor modulator (SERM) clomiphene citrate and the aromatase inhibitor anastrozole. But these have their drawbacks, Dr. Sadeghi-Nejad pointed out; in the overweight population in particular, they “are not necessarily ideal,” he said.

“Although both are viable treatments for enhancing hormonal balance and semen parameters, clomiphene citrate has rare but documented side effects, including thromboembolism, gastrointestinal distress and occasional weight gain in men,” Dr. Sadeghi-Nejad and his colleagues wrote. “Furthermore, despite clomiphene citrate’s association with significant increases in sperm concentration, it is not universally effective, with a meta-analysis indicating a significant increase in sperm concentration in approximately 60% of men.” 

For men who have obesity and oligospermia but normal levels of testosterone and estradiol, “conventional pharmaceutical approaches like clomiphene may not be suitable,” the authors wrote. 

Still, GLP-1 RAs may have a role to play for this population. 

“I think it is within the wheelhouse of a reproductive urologist to consider those types of medications,” Dr. Lindsey said. For example, for a patient who has overweight or obesity, “does it make sense to think about doing clomiphene therapy, which we often do for someone who has low testosterone, in conjunction [with a GLP-1 agonist]? Maybe there’s a kind of an additive effect of having both on board.”

Dr. Ramasamy similarly noted that GLP-1 agonists cannot replace SERMs but may work “synergistically” with them.

“Despite the established popularity of GLP-1 receptor agonists, there may be some reluctance among urologists and fertility specialists to prescribe them, with some others advocating for their use to enhance semen parameters,” Dr. Ramasamy said. “However, robust scientific evidence is still lacking, necessitating caution and a wait for more substantial data.”

Even if GLP-1 RAs prove to have therapeutic benefit for fertility, considerations such as availability and cost may affect prescribing. 

“We do currently have safe and effective drugs that we use for male fertility, and those are generally nowhere near as expensive,” Dr. Bole said. “When we start talking about another drug that we can add, we have to think about the efficacy and the potential side effect but also, is this affordable for patients?” 

Eventually, once more evidence become available, all of the urologists who spoke with this news organization said that they expect discussion about the possible therapeutic utility of GLP-1 agonists to make its way into clinical guidelines.

“Obesity is such a huge impediment for fertility in the modern environment,” Dr. Machineni said. “We will have to clarify the use of these agents, so I think this will be a part of the guidelines some point, but I think we need more information.”

The research was funded by the National Institute of Diabetes and Digestive and Kidney Diseases and the American Cancer Society. The review authors and other quoted physicians reported no disclosures. Dr. Machineni has consulted for Novo Nordisk and Lilly and has conducted clinical trials with semaglutide and tirzepatide for those companies.

Injectable weight loss drugs like Wegovy, Saxenda, and Zepbound have been getting all the glory lately, but they’re not for everyone. If the inconvenience or cost of weight-loss drugs isn’t for you, another approach may be boosting your gut microbiome.

So how does one do that, and how does it work?

“There are a lot of different factors naturally in weight gain and weight loss, so the gut microbiome is certainly not the only thing,” said Chris Damman, MD, a gastroenterologist at the University of Washington. He studies how food and the microbiome affect your health. “With that caveat, it probably is playing an important role.”
 

Trillions of Microbes

The idea that your gut is home to an enormous range of tiny organisms — microbes — has existed for more than 100 years, but only in the 21st century have scientists had the ability to delve into specifics. 

We now know you want a robust assortment of microbes in your gut, especially in the lower gut, your colon. They feast on fiber from the food you eat and turn it into substances your body needs. Those substances send signals all over your body.

If you don’t have enough microbes or have too many of the wrong kinds, it influences those signals, which can lead to health problems. Over the last 20 years, research has linked problems in the gut microbiome to a wide variety of conditions, including inflammatory bowel disease, autoimmune diseases like rheumatoid arthritis, metabolic ones like diabetes, and cardiovascular disease, asthma, and even autism.

Thanks to these efforts, we know a lot about the interactions between your gut and the rest of your body, but we don’t know exactly how many things happen — whether some teeny critters within your microbiome cause the issues or vice versa.

“That’s the problem with so much of the microbiome stuff,” said Elizabeth Hohmann, MD, a physician investigator at the Massachusetts General Research Institute. “Olympic athletes have a better gut microbiome than most people. Well, sure they do — because they’re paying attention to their diet, they’re getting enough rest. Correlation does not causation make.”
 

The American Diet Messes With Your Gut

If you’re a typical American, you eat a lot of ultra-processed foods — manufactured with a long ingredients list that includes additives or preservatives. According to one study, those foods make up 73% of our food supply. That can have a serious impact on gut health.

“When you process a food and mill it, it turns a whole food into tiny particles,” Dr. Damman said. “That makes the food highly digestible. But if you eat a stalk of broccoli, a large amount of that broccoli in the form of fiber and other things will make its way to your lower gut, where it will feed microbes.”

With heavily processed foods, on the other hand, most of it gets digested before it can reach your lower gut, which leaves your microbes without the energy they need to survive.

Rosa Krajmalnik-Brown, PhD, is director of the Biodesign Center for Health Through Microbiomes at Arizona State University. Her lab has done research into how microbes use the undigested food that reaches your gut. She describes the problem with processed foods this way:

“Think about a Coke. When you drink it, all the sugar goes to your bloodstream, and the microbes in your gut don’t even know you’ve had it. Instead of drinking a Coke, if you eat an apple or something with fiber, some will go to you and some to the microbes. You’re feeding them, giving them energy.”
 

Weight and Your Gut Microbiome

The link between gut health and body weight has received a lot of attention. Research has shown, for example, that people with obesity have less diversity in their gut microbiome, and certain specific bacteria have been linked to obesity. In animal studies, transplanting gut microbes from obese mice to “germ-free” mice led those GF mice to gain weight. This suggests excess weight is, in fact, caused by certain microbes, but to date there’s scant evidence that the same is true with humans.

Dr. Krajmalnik-Brown’s group did an experiment in which they had people follow two different diets for 23 days each, with a break in between. Both provided similar amounts of calories and macronutrients each day but via different foods. The study’s typical Western menu featured processed foods — think grape juice, sandwiches made with deli turkey and white bread, and spaghetti with jarred sauce and ground beef. The other menu, what researchers called a “microbiome enhancer diet,” included foods like whole fruit, veggie sandwiches on multigrain buns, and steak with a side of whole wheat spaghetti.

While the study wasn’t designed for weight loss, an interesting thing happened when researchers analyzed participants’ bowel movements.

“We found that when you feed subjects a diet designed to provide more energy to the microbes and not to the [body], our subjects lost a little weight,” Dr. Krajmalnik-Brown said. “It looks like by feeding your microbes, it seems to make people healthier and potentially even lose a little.”

Another possible mechanism involves the same hormone that powers those injectable weight loss drugs. The lower part of your gut makes hormones that tell the entire gut to slow down and also help orchestrate metabolism and appetite. Among them is GLP-1. The drugs use a synthetic version, semaglutide or tirzepatide, to trigger the same effect.

According to Dr. Damman, you can stimulate your gut to make those helpful hormones with the food you eat — by giving your microbes the right fuel.
 

Eat to Feed Your Microbes

The foods you eat can affect your gut microbiome and so your weight. But don’t go looking for that one perfect ingredient, experts warn.

“Oftentimes we get this micro-focus, is this a good food or a bad food?” warned Katie Chapmon, a registered dietitian whose practice focuses on gut health. “You just want to make sure your microbiome is robust and healthy, so it communicates that your body is running, you’ve got it.”

Instead, try to give your body more of the kinds of food research has shown can feed your microbiome, many of which are plant-based. “Those are the things that are largely taken out during processing,” Dr. Damman said. He calls them the “Four Fs”:

Fiber: When you eat fiber-rich foods like fruits, vegetables, whole grains, nuts, and beans, your body can’t digest the fiber while it’s in the upper parts of your GI tract. It passes through to your lower gut, where healthy bacteria ferment it. That produces short-chain fatty acids, which send signals throughout your body, including ones related to appetite and feeling full.

Phenols: Phenolic compounds are antioxidants that give plant-based foods their color — when you talk about eating the rainbow, you’re talking about phenols. The microbes in your gut feed on them, too. “My goal for a meal is five distinct colors on the plate,” Ms. Chapmon said. “That rounds out the bases for the different polyphenols.”

Fermented foods: You can get a different kind of health benefit by eating food that’s already fermented — like sauerkraut, kimchi, kefir, yogurt, miso, tempeh, and kombucha. Fermentation can make the phenols in foods more accessible to your body. Plus, each mouthful introduces good bacteria into your body, some of which make it down to your gut. The bacteria that are already there feed on these new strains, which helps to increase the diversity of your microbiome.

Healthy fats: Here, it’s not so much about feeding the good bacteria in your microbiome. Dr. Damman says that omega-3 fatty acids, found in fatty fish, canola oil, some nuts, and other foods, decrease inflammation in the lining of your gut. Plus, healthy fat sources like extra-virgin olive oil and avocados are full of phenols.

Eating for gut health isn’t a magic bullet in terms of weight loss. But the benefits of a healthy gut go far beyond shedding a few pounds.

“I think we need to strive for health, not weight loss.” Dr. Krajmalnik-Brown said. “Keep your gut healthy and your microbes healthy, and that should eventually lead to a healthy weight. You’ll make your microbes happy, and your microbes do a lot for your health.”

TOPLINE:

“Eating as Treatment” (EAT), a psychological intervention led by oncology dietitians, significantly improves nutritional status and survival in patients with head and neck cancer receiving radiotherapy, new research showed.

METHODOLOGY:

•  It is common in nearly 80% of patients with head and neck cancer and is associated with a higher burden of disease, poorer treatment outcomes, and increased mortality.
• With the EAT intervention, trained oncology dietitians provide a combination of motivational interviewing and cognitive behavior therapy strategies to improve nutritional behaviors in patients with head and neck cancer receiving radiotherapy at six different Australian hospitals.
• The initial EAT trial — which randomly allocated 307 patients with head and neck cancer undergoing radiotherapy between 2013 and 2016 to the EAT intervention or standard diet advice — demonstrated improved nutritional status and quality of life in patients assigned to the EAT intervention.
• The researchers are now reporting an exploratory analysis of 5-year mortality among trial participants.

TAKEAWAY:

• There were 64 deaths over 5 years — 36 (24%) in the control group and 28 (18%) in the intervention group.
• Adjusted logistic regression analyses showed statistically significantly reduced odds of dying in the 5 years following radiotherapy in the intervention group (odds ratio, 0.33; P = .04).
• With the EAT intervention, there was a 17% (P = .03) absolute risk reduction and a 55% relative risk reduction in 5-year mortality (P = .04), with 6 being the number needed to treat to avoid one death.
• Using the Kaplan-Meier survival curve, there was an unadjusted 5-year actuarial survival rate of 76% (0.68-0.82) for the control group and 82% (0.75-0.87) for the intervention phase (P = .22).

IN PRACTICE:

“Our findings provide evidence that a behavioral intervention delivered during [radiotherapy] may substantially reduce mortality rates for patients with [head and neck cancer],” researchers wrote. “Although the mechanism of this reduction is unknown, the randomized study design and the results of this trial strengthen the association between improved nutritional status and oral intake during radiotherapy, and survival benefit.”

SOURCE:

The study, with first author Ben Britton, PhD, from the University of Newcastle, Callaghan, Australia, was published online in the International Journal of Radiation Oncology, Biology, Physics.

LIMITATIONS:

The study relied on the accuracy of the National Death Index, and it was unknown if the recorded deaths were due to cancer or another cause.

DISCLOSURES:

The EAT trial was funded by the Australian National Health and Medical Research Council. The authors had declared no conflicts of interest.

A decline in antibiotic-resistant bacteria has been observed in European countries that have curbed the use of antibiotics in both animals and humans, revealed the fourth joint interagency antimicrobial consumption and resistance analysis report.

The report was published by the European Centre for Disease Prevention and Control, the European Food Safety Authority, and the European Medicines Agency. Its findings were derived from an integrated analysis of the potential relationship between antimicrobial consumption (AMC) by humans and animals and the occurrence of antimicrobial resistance (AMR) using data collected between 2019 and 2021.
 

A Real Threat

AMR poses a significant threat to public and animal health, causing more than 35,000 deaths annually in the European Union (EU) and the European Economic Area. It also imposes a substantial economic burden on European healthcare systems, amounting to approximately €11.7 billion per year.

To address this challenge, the Council of the European Union recommended concerted and sustained efforts to achieve a 20% reduction in AMC in humans (compared with 2019 levels) and a 50% reduction in food-producing animals (compared with 2018 levels) by 2030. These targets are outlined in the European Commission’s Farm to Fork strategy.
 

It Really Works

Analysis of the trends of AMC and AMR in Escherichia coli from humans and food-producing animals, conducted for the first time, revealed that the susceptibility of E coli to antimicrobials in humans and animals increases with an overall decrease in the consumption of antibiotics.

Concurrent trends in AMC and AMR from 2014 to 2021 were also assessed. AMC in both human and animal sectors, measured in mg/kg of estimated biomass, was compared at country and European levels. In 2021, human AMC totaled 125.0 mg/kg of biomass, while food-producing animals registered 92.6 mg/kg of biomass.

Over the 2014-2021 period, total AMC in food-producing animals decreased by 44%, while in humans, it remained relatively stable. The consumption of certain antimicrobials was positively associated with resistance to those substances in bacteria from both humans and food-producing animals.

The report also highlighted that E coli resistance is linked in humans to the use of carbapenems, third- and fourth-generation cephalosporins, and quinolones and in food-producing animals to the administration of quinolones, polymyxins, aminopenicillins, and tetracyclines. Further, a connection exists between bacterial resistance in humans and food-producing animals, particularly for bacterial species such as Campylobacter jejuni and C coli.

The findings suggest that measures to reduce AMC in both food-producing animals and humans have been effective in many countries. However, reinforcing these measures is crucial to maintain and further advance reductions in AMC.
 

More Work

Aligned with the European Commission’s One Health holistic and coordinated approach to managing the human and veterinary sectors together, the European agencies advocate for:

• Sustained efforts to combat AMR at national, EU, and global levels.
• Coordinated surveillance of antibiotic use and AMR in both human and animal sectors.
• Continued research in the field of AMR.

The statistical code used to conduct these analyses was made publicly available in order to support further research analyses.

A decline in antibiotic-resistant bacteria has been observed in European countries that have curbed the use of antibiotics in both animals and humans, revealed the fourth joint interagency antimicrobial consumption and resistance analysis report.

The report was published by the European Centre for Disease Prevention and Control, the European Food Safety Authority, and the European Medicines Agency. Its findings were derived from an integrated analysis of the potential relationship between antimicrobial consumption (AMC) by humans and animals and the occurrence of antimicrobial resistance (AMR) using data collected between 2019 and 2021.
 

A Real Threat

AMR poses a significant threat to public and animal health, causing more than 35,000 deaths annually in the European Union (EU) and the European Economic Area. It also imposes a substantial economic burden on European healthcare systems, amounting to approximately €11.7 billion per year.

To address this challenge, the Council of the European Union recommended concerted and sustained efforts to achieve a 20% reduction in AMC in humans (compared with 2019 levels) and a 50% reduction in food-producing animals (compared with 2018 levels) by 2030. These targets are outlined in the European Commission’s Farm to Fork strategy.
 

It Really Works

Analysis of the trends of AMC and AMR in Escherichia coli from humans and food-producing animals, conducted for the first time, revealed that the susceptibility of E coli to antimicrobials in humans and animals increases with an overall decrease in the consumption of antibiotics.

Concurrent trends in AMC and AMR from 2014 to 2021 were also assessed. AMC in both human and animal sectors, measured in mg/kg of estimated biomass, was compared at country and European levels. In 2021, human AMC totaled 125.0 mg/kg of biomass, while food-producing animals registered 92.6 mg/kg of biomass.

Over the 2014-2021 period, total AMC in food-producing animals decreased by 44%, while in humans, it remained relatively stable. The consumption of certain antimicrobials was positively associated with resistance to those substances in bacteria from both humans and food-producing animals.

The report also highlighted that E coli resistance is linked in humans to the use of carbapenems, third- and fourth-generation cephalosporins, and quinolones and in food-producing animals to the administration of quinolones, polymyxins, aminopenicillins, and tetracyclines.

TOPLINE: 

Accelerometer-measured physical activity (PA), whether light, moderate, or vigorous, is associated with lower risk for heart failure (HF) in older women while more sedentary time is associated with higher HF risk in these women, results of a new study suggest. 

METHODOLOGY:

• The analysis included 5951 women aged 63-99 years (mean age, 78.6 years), including 33.7% Black, 17.2% Hispanic, and 49.2% White individuals without HF from the Objective Physical Activity and Cardiovascular Health (OPACH) study, an ancillary to the Women’s Health Initiative Long-Life Study.
• Participants wore an accelerometer on their hip 24 hours a day for up to 7 consecutive days except when in water, kept nightly sleep logs, completed questionnaires to provide information on medical history and sociodemographic and lifestyle factors, and self-rated their general health status.
• Researchers recorded their use of assistive walking devices; determined body mass index as well as blood pressure; obtained fasting serum glucose, total and high-density lipoprotein cholesterol, triglyceride, and high-sensitivity C-reactive protein concentrations; and scored participants’ multimorbidity.
• They determined intensity-specific PA using vector magnitude acceleration cut points (light PA, 19-518 counts/15 s; moderate to vigorous PA [MVPA], > 518) and steps per day using dedicated software, and they quantified sedentary time (total and mean bout duration).
• The primary outcome was overall self-reported HF later adjudicated by physicians using medical record reviews; secondary endpoints were heart failure with reduced ejection fraction (HFrEF) and preserved EF (HFpEF), classified by an EF of < 45% or 45% or > 45%, respectively, after cardiac imaging.

TAKEAWAY:

• A total of 407 HF cases (including 257 HFpEF and 110 HFrEF) were identified during a mean of 7.5 years of follow-up.
• HFrEF was not associated with PA measures in the fully adjusted model (which controlled extensively for health and physical functioning status), but overall HF and HFpEF were inversely associated with total PA (per 1-standard deviation [SD] increment: hazard ratio [HR] 0.85; 95% CI, 0.75-0.95 and HR, 0.78; 95% CI, 0.67-0.91, respectively), light PA (HR, 0.88; 95% CI, 0.78-0.98 and HR, 0.80; 95% CI, 0.70-0.93, respectively) and MVPA (HR, 0.84; 95% CI, 0.73-0.97 and HR, 0.85; 95% CI, 0.72-1.01, respectively).
• With regard to daily steps, each 1-SD increment was associated with a significant 26% lower risk for overall HF (HR 0.74; 95% CI, 0.63-0.88) and 29% lower risk for HFpEF (HR, 0.71; 95% CI, 0.57-0.88), with these inverse risks becoming significant at about 2000 steps/d, “far less than the often touted 10,000 steps/d for promoting health benefits,” noted the authors.
• Total sedentary time was positively associated (per 1 SD in the fully adjusted model) with risks of overall HF (HR, 1.17; 95% CI, 1.04-1.33) and HFpEF (HR, 1.29; 95% CI, 1.10-1.51) but not HFrEF; mean sedentary bout duration was significantly inversely associated with HFrEF (per 1 SD: HR, 0.76; 95% CI, 0.61-0.97), although the relatively small number of cases at the extremes of bout duration may contribute to this unexpected inverse association, said the authors.

IN PRACTICE:

The implications of promoting PA, regardless of intensity, for primary HFpEF prevention in later life, “has profound public health and clinical relevance,” the authors concluded. They noted that HFpEF is a “burgeoning epidemic” that disproportionately affects women and minorities with limited available therapies.

STUDY DETAILS:

The study, led by Michael J. LaMonte, PhD, MPH, University at Buffalo-SUNY, Buffalo, New York, was published online on February 21, 2024, in JAMA Cardiology.

LIMITATIONS:

There was only a single accelerometer assessment of PA and sedentary exposures and relatively small numbers of HFrEF cases, which restricted analytic precision. Although researchers controlled for several established vascular biomarkers, they did not have HF-specific measures such as cardiac troponin or N-terminal pro–brain natriuretic peptide. It’s unknown if the findings can be generalized to men and populations dissimilar to women in OPACH.

DISCLOSURES:

The study was funded in part by the National Heart, Lung, and Blood Institute, National Institutes of Health, and US Department of Health and Human Services. LaMonte reported receiving grants from the National Institutes of Health during the conduct of the study; see paper for disclosures of the other authors.

Joseph R. Berger, MD: Hi. I'm Dr Joseph Berger, and I'm joined for this Care Cues conversation with my patient, Michelle Biloon, who has had multiple sclerosis (MS) for the past 6 years. Hello, Michelle. Welcome.

Michelle Biloon: Thank you, Dr Berger.

Berger: Can you tell us a little bit about yourself, how you came to understand you had MS, and how you've done since the diagnosis was rendered?

Biloon: Yeah. It was a very short diagnosis period for me. In the winter of 2017, I started experiencing dizzy spells, and I didn't really know why. I eventually went to my primary care clinic where my doctor is, and they did blood work. Then, they did a CT and didn't see anything, and I just kind of kept feeling worse.

Then, finally, I went to an ENT just to see if it was maybe related to my ears. The ENT actually said, "You need to go to the ER and get an MRI." And while I was in the MRI, I could feel the dizzy spells. And I thought, Well, something is happening. I don't know what it is. And then a resident came in and said that they saw lesions on my brain, and they knew that it was going to be MS or something like it.

Berger: How did you feel about that?

Biloon: At the time, I was kind of glad to hear it was something. And I just asked her if, like, you die from it. That was the first thing I asked. It was like falling off a cliff.

It was making it hard for me to function in what I was doing, which was stand-up comedy, because of the cognitive issues I was having, the cognitive fog. That was how I ended up with you. Right away, you talked to me and were actually able to introduce to me some new medications that are out and are phenomenally better for MS plus were not pills or shots every day. It's made my MS over the years a lot more manageable.

Berger: I'd like to pick up on a couple of things you said.

Biloon: Sure.

Berger: One is, because most people envision MS as this terrible, crippling illness that's going to leave them wheelchair-bound, deprived of their profession, finding it difficult to stay in a marriage it's vested with what has been termed "lamentable results." And one of the first things that we as physicians have to do is to calm people down and say, "You know what. You have MS. You're going to be just fine. Trust me. We have wonderful medications for what you have, and we'll take care of it." In fact, I've made a habit of telling people quit worrying. You hired me to worry for you.

Biloon: Yep.

Berger: And I think that's helpful.

Biloon: I've been just so appreciative of that. There's a balance of being condescended to — do you know what I mean — and also being given information. I'm very sensitive to that balance because I consider myself an intelligent person. And you're being put in a position where someone knows more than you, and you have to listen.

Berger: One of the other challenges we face is getting somebody on a treatment. And we elected to put you on an intravenous therapy every 6 months.

Biloon: Especially because as a stand-up comedian, I was traveling a lot, doing these every-6-months infusion, especially with the high efficacy rate that it had been reported from what we had read and the low amount of side effects. I mean, just those things together was just something that seemed the easiest for me.

Berger: So did you encounter any challenges when we first got you started on the infusion therapy?

Biloon: The first infusion I got was at the hospital. But then after that, I had to go to the suburbs, to a center out there for the infusion. That was difficult because to get a ride out there and a ride back — it was a long trip for someone to wait with me. Taking an Uber is expensive, so was it for me to drive. You don't feel good for a couple of days after. So that was how it was, and I complained about it. Probably at every appointment we had, I complained about it.

Berger: Yeah. So some of the challenges you talked about are very, very common. As a physician on medications myself, I can tell you that I am not particularly compliant. And what I love about infusion therapies is that I know that the patient is getting their medicine. Because when they don't show up for a scheduled appointment, I'm called, and I know.

Biloon: I do have a bit of an allergic reaction to the drug. But that's been easily managed over time. Now, the drug infusions are actually being done at my home, which makes the whole process twice-a-year–world's better.

Berger: But there are other barriers that people confront other than the initiation of drugs. Had you encountered any?

Biloon: I think the problem that I had more so was finding the drugs that would manage some of my symptoms. It took a couple of years to sort of figure out what that would be, both with figuring them out and both dealing with insurance on certain medications.

Berger: That's one sort of problem that we confront. The other, of course, are those individuals who, for a variety of reasons, have difficulty with the diagnosis because of their backgrounds. And they may be sociocultural in nature. Every time you go to the physical therapist, it's some degree of money.

Now for some people, it's trivial. But for others, it's a considerable amount of money, relative to what it is that they earn. And you simply have to work within those confines as best you can.

We do have various programs that help people. So we try to employ them. There are, in addition to the sociocultural barriers, language barriers that we often confront. We, in our situation here in a large city, have a very large migrant population.

Fortunately, most of the people speak languages that either you speak as well, or there's somebody in the next room that speaks pretty well. But that's not always the case. So we do have an interpreter service that has to be employed.

Biloon: I cannot imagine the nuance in speaking to people from different ages and different backgrounds, who have different types of lifestyles, for them to understand.

Berger: I don't write at a computer. I think that really degrades the patient-physician relationship. What I do is I obtain a history. I do it on a piece of paper with a pen or a pencil.

I recapitulate them to the patient in paraphrasing it, to make sure that I have gotten it right and that they understand what I think I heard. That, I think, has been enormously helpful in helping people understand what may happen in the absence of treatment and why the treatment is important. That you can do, regardless of what the person's background is. So that's how I approach it.

Biloon: How do you deal with patients when they're not on the same page with you?

Berger: One important thing is that you have to be patient. That is something that it took me 50 years in medicine to learn. And then accepting the patient's opinion and saying, "All right, go home and think about it," because you often don't convince them when they're in the office with you.

Biloon: I did have a little bit of a cushion between my diagnosis and when we actually saw each other, where I was able to really sit in my thoughts on the different treatments and stuff. By the time that we were able to talk, it reassured me on that was the right plan.

Berger: I'm curious what your experience has been with our MS center.

Biloon: Through the portal, every time I need something, I'm usually reaching out, keeping you up-to-date on my primary care or whether it's trying to get a refill on one of my medications that I have to reach out. I really do feel that having that team there, being able to reach out, that's been extremely helpful to have and keeps me very secure because that's all I really need, especially during the pandemic, right? Because then I was very isolated and dealing with going through MS. So it was great to at least ­— and I did — shoot off emails or texts in the portal, and that's usually primarily how I communicated.

Berger: I will tell you, in my opinion, maybe nine out of 10 messages in the portal or calls that we get simply require reassurance.

Biloon: Yes.

Berger: You just either pick up the phone or shoot back a note, say, "This is not your MS. Don't worry about it." I mean, the most important thing for me is to keep people from worrying because that doesn't solve any problem.

Biloon: No, and it causes stress, which causes fatigue. I mean, it's a bad cycle.

Berger: In the past year, you've actually felt better, and you've gone back to performing. It sounds like the volume of performances has gotten back to what it was pre-illness. What do you see for the future?

Biloon: What I see is traveling more for stand-up and doing the sort of clubs and cities that I had kind of stopped doing from before I was diagnosed, so 2017 and prior to that. And then also even working on other things, writing and maybe even doing sort of books or one-person shows that even talk about sort of my struggles with MS and kind of coming back to where I am. I'm looking forward to the future, and I hope that that's the track I can keep going on.

Berger: I see no reason why you shouldn't.

Biloon: Thank you.

Berger: Michelle, thank you very much for joining me today in this conversation.

Biloon: Thank you so much for having me. It's been really wonderful to be able to sit down here with you.

I eventually went to my primary care clinic where my doctor is, and they did blood work. Then, they did a CT and didn't see anything, and I just kind of kept feeling worse.

Then, finally, I went to an ENT just to see if it was maybe related to my ears. The ENT actually said, "You need to go to the ER and get an MRI." And while I was in the MRI, I could feel the dizzy spells. And I thought, Well, something is happening. I don't know what it is. And then a resident came in and said that they saw lesions on my brain, and they knew that it was going to be MS or something like it.

Berger: How did you feel about that?

Biloon: At the time, I was kind of glad to hear it was something. And I just asked her if, like, you die from it. That was the first thing I asked. It was like falling off a cliff.

It was making it hard for me to function in what I was doing, which was stand-up comedy, because of the cognitive issues I was having, the cognitive fog. That was how I ended up with you. Right away, you talked to me and were actually able to introduce to me some new medications that are out and are phenomenally better for MS plus were not pills or shots every day. It's made my MS over the years a lot more manageable.

Berger: I'd like to pick up on a couple of things you said.

Biloon: Sure.

Berger: One is, because most people envision MS as this terrible, crippling illness that's going to leave them wheelchair-bound, deprived of their profession, finding it difficult to stay in a marriage it's vested with what has been termed "lamentable results." And one of the first things that we as physicians have to do is to calm people down and say, "You know what. You have MS. You're going to be just fine. Trust me. We have wonderful medications for what you have, and we'll take care of it." In fact, I've made a habit of telling people quit worrying. You hired me to worry for you.

Biloon: Yep.

Berger: And I think that's helpful.

Biloon: I've been just so appreciative of that. There's a balance of being condescended to — do you know what I mean — and also being given information. I'm very sensitive to that balance because I consider myself an intelligent person. And you're being put in a position where someone knows more than you, and you have to listen.

Berger: One of the other challenges we face is getting somebody on a treatment. And we elected to put you on an intravenous therapy every 6 months.

Biloon: Especially because as a stand-up comedian, I was traveling a lot, doing these every-6-months infusion, especially with the high efficacy rate that it had been reported from what we had read and the low amount of side effects. I mean, just those things together was just something that seemed the easiest for me.

Berger: So did you encounter any challenges when we first got you started on the infusion therapy?

Biloon: The first infusion I got was at the hospital. But then after that, I had to go to the suburbs, to a center out there for the infusion. That was difficult because to get a ride out there and a ride back — it was a long trip for someone to wait with me. Taking an Uber is expensive, so was it for me to drive. You don't feel good for a couple of days after. So that was how it was, and I complained about it. Probably at every appointment we had, I complained about it.

Berger: Yeah. So some of the challenges you talked about are very, very common. As a physician on medications myself, I can tell you that I am not particularly compliant. And what I love about infusion therapies is that I know that the patient is getting their medicine. Because when they don't show up for a scheduled appointment, I'm called, and I know.

Biloon: I do have a bit of an allergic reaction to the drug. But that's been easily managed over time. Now, the drug infusions are actually being done at my home, which makes the whole process twice-a-year–world's better.

Berger: But there are other barriers that people confront other than the initiation of drugs. Had you encountered any?

Biloon: I think the problem that I had more so was finding the drugs that would manage some of my symptoms. It took a couple of years to sort of figure out what that would be, both with figuring them out and both dealing with insurance on certain medications.

Berger: That's one sort of problem that we confront. The other, of course, are those individuals who, for a variety of reasons, have difficulty with the diagnosis because of their backgrounds. And they may be sociocultural in nature. Every time you go to the physical therapist, it's some degree of money.

Now for some people, it's trivial. But for others, it's a considerable amount of money, relative to what it is that they earn. And you simply have to work within those confines as best you can.

We do have various programs that help people. So we try to employ them. There are, in addition to the sociocultural barriers, language barriers that we often confront. We, in our situation here in a large city, have a very large migrant population.

Fortunately, most of the people speak languages that either you speak as well, or there's somebody in the next room that speaks pretty well. But that's not always the case. So we do have an interpreter service that has to be employed.

Biloon: I cannot imagine the nuance in speaking to people from different ages and different backgrounds, who have different types of lifestyles, for them to understand.

Berger: I don't write at a computer. I think that really degrades the patient-physician relationship. What I do is I obtain a history. I do it on a piece of paper with a pen or a pencil.

I recapitulate them to the patient in paraphrasing it, to make sure that I have gotten it right and that they understand what I think I heard. That, I think, has been enormously helpful in helping people understand what may happen in the absence of treatment and why the treatment is important. That you can do, regardless of what the person's background is. So that's how I approach it.

Biloon: How do you deal with patients when they're not on the same page with you?

Berger: One important thing is that you have to be patient. That is something that it took me 50 years in medicine to learn. And then accepting the patient's opinion and saying, "All right, go home and think about it," because you often don't convince them when they're in the office with you.

Biloon: I did have a little bit of a cushion between my diagnosis and when we actually saw each other, where I was able to really sit in my thoughts on the different treatments and stuff. By the time that we were able to talk, it reassured me on that was the right plan.

Berger: I'm curious what your experience has been with our MS center.

Biloon: Through the portal, every time I need something, I'm usually reaching out, keeping you up-to-date on my primary care or whether it's trying to get a refill on one of my medications that I have to reach out. I really do feel that having that team there, being able to reach out, that's been extremely helpful to have and keeps me very secure because that's all I really need, especially during the pandemic, right? Because then I was very isolated and dealing with going through MS. So it was great to at least ­— and I did — shoot off emails or texts in the portal, and that's usually primarily how I communicated.

Berger: I will tell you, in my opinion, maybe nine out of 10 messages in the portal or calls that we get simply require reassurance.

Biloon: Yes.

Berger: You just either pick up the phone or shoot back a note, say, "This is not your MS. Don't worry about it." I mean, the most important thing for me is to keep people from worrying because that doesn't solve any problem.

Biloon: No, and it causes stress, which causes fatigue. I mean, it's a bad cycle.

Berger: In the past year, you've actually felt better, and you've gone back to performing. It sounds like the volume of performances has gotten back to what it was pre-illness. What do you see for the future?

Biloon: What I see is traveling more for stand-up and doing the sort of clubs and cities that I had kind of stopped doing from before I was diagnosed, so 2017 and prior to that. And then also even working on other things, writing and maybe even doing sort of books or one-person shows that even talk about sort of my struggles with MS and kind of coming back to where I am. I'm looking forward to the future, and I hope that that's the track I can keep going on.

Berger: I see no reason why you shouldn't.

Biloon: Thank you.

Berger: Michelle, thank you very much for joining me today in this conversation.

Biloon: Thank you so much for having me. It's been really wonderful to be able to sit down here with you.

Joseph R. Berger, MD: Hi. I'm Dr Joseph Berger, and I'm joined for this Care Cues conversation with my patient, Michelle Biloon, who has had multiple sclerosis (MS) for the past 6 years. Hello, Michelle. Welcome.

The risk of being hospitalized because of COVID-19 was reduced by 84% among people who used Paxlovid, reports a new study.

This medicine has been approved for use in the United States for people over 12 years old who are at risk of having a severe COVID-19 infection. 

The study was published in the Journal of Antimicrobial Chemotherapy.

Study authors examined the health records of almost 45,000 outpatients who tested positive for COVID-19 from January to August 2022. This sample period was when the Omicron strain was dominant.

The average patient age was 47. Sixty-two percent were White, 24% were Black, 6% were Hispanic, and 8% had an unknown ethnicity. A slight majority, 51%, had received two or more vaccine doses before the study period.

From the study group, 201 people were hospitalized within 28 days of their positive COVID test.

Almost 5,000 people in the study group received Paxlovid. The use of Paxlovid was the best indicator of avoiding hospitalization, with three of those people being hospitalized.

“Patients who were treated with Paxlovid were twice as likely to have received at least two doses of COVID-19 vaccine,” the University of Minnesota’s CIDRAP reported. “They were also more likely to be 70 years or older.”

People taking Paxlovid were more likely to be White and to live in middle- or upper-income areas.

“COVID-19 hospitalization risk was reduced by 84% among [Paxlovid] recipients in a large, diverse healthcare system during the Omicron wave,” the study’s authors wrote. “These results suggest that [Paxlovid] remained highly effective in a setting substantially different than the original clinical trials.”

TOPLINE:

Intermittent hypoxemia prompted higher postprandial plasma triglyceride levels in men than in women compared with normoxia.

METHODOLOGY:

• Potential gender differences in the impact of intermittent hypoxemia on triglycerides have not been well studied, despite the increased risk for metabolic comorbidities in obstructive sleep apnea (OSA).
• The researchers recruited 24 healthy young adults with a mean age of 23.3 years for the 12 men and 21.3 years for the 12 women.
• Participants consumed a high-fat meal followed by 6 hours of exposure to intermittent hypoxemia or ambient air; the primary outcome was changes in postprandial plasma triglyceride levels.

TAKEAWAY:

• Intermittent hypoxemia was associated with significantly higher postprandial triglycerides in men but not in women.
• Women had lower levels of total triglycerides as well as denser triglyceride-rich lipoprotein triglycerides (TRL-TG) and buoyant TRL-TG in both normoxia and hypoxemia conditions compared with men.
• Glucose levels were significantly higher in men and significantly lower in women during intermittent hypoxemia compared with normoxia (P < .001 for both sexes).

IN PRACTICE:

“Although there is a need for larger confirmatory studies in individuals living with obstructive sleep apnea, this study demonstrates that intermittent hypoxemia alters triglyceride metabolism differently between men and women,” the researchers wrote.

SOURCE:

The lead author of the study was Nicholas Goulet, MD, of the University of Ottawa, Ottawa, Ontario, Canada. The study was published online in The Journal of Physiology on January 29, 2024.

LIMITATIONS:

Limitations of the study included the experimental design with simulated OSA, the small and homogeneous study population, the use of a specific profile for intermittent hypoxemia, and the use of a specific high-fat meal.

DISCLOSURES:

The study was supported by the Natural Sciences and Engineering Research Council of Canada and the Association Médicale Universitaire de l’Hôpital Montfort. The researchers had no financial conflicts to disclose.

The results of a large longitudinal study spanning several years support a decrease in the risk for dementia among older adults who regularly use the Internet for < 2 hours per day. 

Several cross-sectional and longitudinal studies (though with relatively short follow-up periods) suggest that regular Internet use helps maintain cognitive reserve, although some observers have voiced skepticism. This hypothesis is particularly relevant for older patients facing the potentially detrimental effects of brain aging. According to some studies, memory, cognitive performance, and verbal reasoning tend to be better preserved among Internet users.

Several factors come into play, including socioeconomic disparities, socio-educational level, and generational differences, since Internet usage varies qualitatively and quantitatively with age. Older patients theoretically have more limited Internet usage. Under these conditions, the effect on cognitive functions would likely be modest compared with generations who were immersed in digital technology early on and tend to overuse it. After a certain age, accelerated brain aging would weigh much more heavily than any potential positive effects of the Internet. It is worth noting that the negative effects of Internet use have mainly been studied in young subjects, thus there is a lack of data concerning older patients.

Nearly 20,000 Participants

These considerations highlight the significance of a longitudinal cohort study that included 18,154 adults aged 50-64.9 years who were free from any dementia at baseline. These adults were participating in the Health and Retirement Study. The median follow-up period was 7.9 years, and follow-up extended to 17.1 years in some cases. Given that adults with better cognitive health are likely to self-select as regular users, the propensity score method was employed to control for this nonrandom factor using inverse probability weighting.

The risk for dementia based on initial Internet use was estimated using the Cox proportional hazards model, incorporating potentially late entry into the workforce and several covariables. Interactions with education level, gender, generation, and ethnic origin were also considered. Cumulative Internet exposure in terms of regular periodic use throughout life was included in the statistical analysis, as well as the hours spent on this activity each day. The analyses were conducted from September 2021 to November 2022.

Risk Nearly Halved

Regular Internet use was associated with a reduced risk for dementia, compared with irregular use. The hazard ratio (HR) for dementia was estimated at 0.57. After adjustment for the nonrandom factor of self-selection, this association persisted, and the HR decreased to 0.54. Accounting for baseline cognitive decline did not substantially change these results and yielded an HR of 0.62. The difference in risk between regular and irregular users was not altered by considering potential confounding factors such as education level, ethnic origin, gender, or generation. The longer the cumulative exposure over life, the lower the risk for dementia during follow-up.

The relationship between dementia risk and daily Internet usage hours seems to follow a U-shaped curve, with the lowest risk observed for durations between 0.1 and 2 hours. However, these estimates did not reach statistical significance because of the small sample size analyzed.

The risk for dementia appears to be approximately twice as low among regular Internet users compared with nonusers. This hypothesis deserves serious consideration because of the large sample size and long follow-up duration, as well as careful consideration of as many potential confounding factors as possible. Potential negative effects remain to be clarified as the study was not designed to detect them. The results of previous studies suggest that Internet usage should be moderate for optimal benefit, with approximately 2 hours per day being the most suitable duration, regardless of age, until proven otherwise.

The results of a large longitudinal study spanning several years support a decrease in the risk for dementia among older adults who regularly use the Internet for < 2 hours per day. 

Several cross-sectional and longitudinal studies (though with relatively short follow-up periods) suggest that regular Internet use helps maintain cognitive reserve, although some observers have voiced skepticism. This hypothesis is particularly relevant for older patients facing the potentially detrimental effects of brain aging. According to some studies, memory, cognitive performance, and verbal reasoning tend to be better preserved among Internet users.

Several factors come into play, including socioeconomic disparities, socio-educational level, and generational differences, since Internet usage varies qualitatively and quantitatively with age. Older patients theoretically have more limited Internet usage. Under these conditions, the effect on cognitive functions would likely be modest compared with generations who were immersed in digital technology early on and tend to overuse it. After a certain age, accelerated brain aging would weigh much more heavily than any potential positive effects of the Internet. It is worth noting that the negative effects of Internet use have mainly been studied in young subjects, thus there is a lack of data concerning older patients.

Nearly 20,000 Participants

These considerations highlight the significance of a longitudinal cohort study that included 18,154 adults aged 50-64.9 years who were free from any dementia at baseline. These adults were participating in the Health and Retirement Study. The median follow-up period was 7.9 years, and follow-up extended to 17.1 years in some cases. Given that adults with better cognitive health are likely to self-select as regular users, the propensity score method was employed to control for this nonrandom factor using inverse probability weighting.

The risk for dementia based on initial Internet use was estimated using the Cox proportional hazards model, incorporating potentially late entry into the workforce and several covariables. Interactions with education level, gender, generation, and ethnic origin were also considered. Cumulative Internet exposure in terms of regular periodic use throughout life was included in the statistical analysis, as well as the hours spent on this activity each day. The analyses were conducted from September 2021 to November 2022.

Risk Nearly Halved

Regular Internet use was associated with a reduced risk for dementia, compared with irregular use. The hazard ratio (HR) for dementia was estimated at 0.57. After adjustment for the nonrandom factor of self-selection, this association persisted, and the HR decreased to 0.54. Accounting for baseline cognitive decline did not substantially change these results and yielded an HR of 0.62. The difference in risk between regular and irregular users was not altered by considering potential confounding factors such as education level, ethnic origin, gender, or generation. The longer the cumulative exposure over life, the lower the risk for dementia during follow-up.

TOPLINE:

Eosinopenia and low ratio between eosinophil count (EC) and neutrophil count (NC) are potential indicators of infection for patients with inflammatory disease who are treated with tocilizumab.

METHODOLOGY:

• The researchers reviewed data from 163 patients treated for an inflammatory disease (mostly rheumatoid arthritis) with tocilizumab at a single center between 2009 and 2020.
• The study population included 41 patients with unscheduled hospitalizations for suspected infections. Patients’ median age was 59 years, and 83% were female.
• The researchers assessed the association in tocilizumab-treated patients between infections and eosinopenia (defined as EC < 0.05 g/L) and a low ratio between EC and NC, defined as EC/NC × 1000 < 11.8.

TAKEAWAY:

• Infectious diseases were diagnosed in 20 of the hospitalized patients (49%); the most common diseases were pneumonia (30%), joint or bone infections (25%), and gastrointestinal tract infections (15%).
• The median absolute EC at hospital admission was significantly lower for patients with infections than for those without infections (0.06 g/L vs 0.20 g/L).
• The median EC/NC × 1000 ratios were significantly lower in infected patients vs noninfected patients (6.54 vs 48.50).
• No differences appeared between patients with and without infections in age, sex, type of inflammatory disease, and steroid treatment.

IN PRACTICE:

“This original study suggests that all those easily available parameters should be used to maximize [sensitivity] in the screening of infection in patients undergoing treatment with IL-6 pathway antagonists,” the researchers wrote.

SOURCE:

The lead author on the study was Audrey Glatre, MD, of University Hospital Centre Reims, France. The study was published online in RMD Open on February 9.

LIMITATIONS:

The retrospective, observational design; relatively small study population; and use of data from a single center were potential limitations of the findings.

DISCLOSURES:

The study received no outside funding. The researchers had no financial conflicts to disclose.
