Clinician Reviews

ANAHEIM, CALIF. – Alpha-gal syndrome (AGS) is commonly described as an allergy to red meat, but that is “just the beginning,” allergist and immunologist Scott P. Commins, MD, PhD, told attendees at the annual meeting of the American College of Allergy, Asthma, and Immunology (ACAAI) annual meeting.

Dr. Commins, associate chief for allergy and immunology at the University of North Carolina at Chapel Hill, has made alpha-gal, a potentially fatal allergy, which, in the United States is tied to the bite of the Lone Star tick, his primary research focus.

Beyond red meat, “there are some people who are allergic to all things mammal,” he explained. Dairy products from mammals, medical devices made from mammalian products, vaccines and medicines that contain gelatin, and even commercial products such as perfumes and cosmetics may be behind an AGS reaction.

“The derived products from pigs and cows really find their way into a lot of our day-to-day products,” he said. “I try to keep an open mind about these exposures.”

Physicians should also be aware that “this can happen to kids,” said Dr. Commins. “It looks very similar to adults’ [AGS]. They can end up in the emergency department.”

He also had clinical advice about food challenges for AGS. He explained that there’s more alpha-gal in beef than in other red meats (including pork, venison, and lamb) with the exception of pork kidney. Pork kidney, he said, “has the most alpha-gal that we can find in the lab.”

Dr. Commins said he has stopped using beef for AGS food challenges and has switched to pork sausage patties with a high fat content microwaved in the clinic because they have less alpha-gal in general and he views them as safer.

Long delay in symptom onset

AGS symptoms typically take 2-6 hours to appear after eating red meat or being exposed to mammalian products, but Dr. Commins related a story about a patient he sent home who had very mild symptoms (some lower back itching) after he had spent the day at the clinic after a pork sausage food challenge for AGS.

The patient had returned home. Eight hours after the food challenge, his wife sent Dr. Commins a picture of her husband’s back, which was riddled with welts and was itching badly.

“I learned that if you’re going to do these food challenges, if there is a hint of symptoms at the clinic at 6 hours, keep them in the clinic, because it may really take that long to evolve,” Dr. Commins said.

One of the early signs he’s discovered is palmar erythema (redness and swelling of the hands).

Research has shown that AGS has been heavily concentrated in the Southeast, where Lone Star tick populations are clustered, but research has shown that from 2017 to 2022, it moved up the East Coast to the central United States and Upper Midwest.

“We are seeing increasing diagnoses of AGS in places that are not, perhaps, where we first thought this allergy existed,” said Dr. Commins. “Stay aware,” he cautioned.

The allergy is not exclusive to the United States, he noted. In Europe and Australia, for example, AGS is not thought to be tied to the Lone Star tick, which doesn’t inhabit those regions.

“It is a global phenomenon,” Dr. Commins said.

In August, the CDC alerted physicians to emerging cases of alpha-gal allergy after an article in Morbidity and Mortality Weekly Report indicated that health care providers have little knowledge about the allergy. Of the 1,500 health care providers surveyed, 42% had never heard of the syndrome, and another 35% were not confident in diagnosing or managing affected patients.

Matthew Lau, MD, an allergist with Kaiser Permanente in Honolulu who listened to Dr. Commins’ talk, told this news organization, “It’s important to raise awareness in primary care particularly, he said, as “allergists see only a fraction of the [AGS] patients.”

Allergists can help raise awareness

“Allergists have a role to alert the general community” and to drive more referrals, he said. That includes emergency departments, where physicians commonly see anaphylaxis.

Dr. Lau said he expects the incidence of AGS to increase, because global warming will likely lengthen warmer seasons and cause the geographic distribution to change.

Jay Lieberman, MD, a pediatric allergist at Le Bonheur Children’s Hospital in Memphis, Tenn., told this news organization, “There’s still a lot of confusion, and hearing from an expert like Dr. Commins helps tease out the not-obvious things about patients who are having more mild symptoms,” such as from allergy to dairy or medicines or vaccines that contain gelatin.

As a pediatric allergist, Dr. Lieberman said he sees less alpha-gal than his colleagues, but, he said, “On the adult side in Tennessee, it’s rampant.”

Dr. Commins, Dr. Lieberman, and Dr. Lau report no relevant financial relationships.

TOPLINE:

People who report frequently adding salt to their food are at significantly greater risk of developing type 2 diabetes (T2D), even after adjustment for confounding factors.

METHODOLOGY:

• Researchers identified 402,982 participants in the UK Biobank from March 2006 to October 2010 who had completed a questionnaire about the frequency with which they added salt to food and who did not have diabetes, chronic kidney disease, cancer, or cardiovascular disease at baseline.
• Urine samples were collected at baseline, sodium and potassium levels were measured, and 24-hour sodium excretion was estimated.
• Investigators followed participants from baseline to diagnosis of diabetes, death, or the censoring date (May 23, 2021), whichever occurred first. Information on T2D events were collected through medical history linkage to data on hospital admissions, questionnaire, and the death register.

TAKEAWAY:

• During a mean follow-up of 11.9 years, 13,120 incident cases of T2D were documented.
• Compared with people who reported “never/rarely” adding salt to food, the sex- and age-adjusted hazard ratios (HRs) for developing T2D were 1.20, 1.32, and 1.86 for those who reported “sometimes,” “usually,” and “always” adding salt, respectively (P-trend < .001).
• After further adjustment for the Townsend deprivation index, education level, income, smoking, drinking, physical activity, and high cholesterol, the association was attenuated but remained significant, with HRs of 1.11, 1.18, and 1.28 for “sometimes,” “usually,” and “always” responses, respectively (P-trend < .001).
• After full adjustment, there was also a dose-dependent relationship across quintiles of urinary sodium and higher T2D risk, with HRs of 1 (reference), 1.12, 1.17, 1.28, and 1.34 for quintiles 2-5, respectively (P-trend < .001).
• Body fat percentage and body fat mass significantly mediated the association of adding salt with T2D, by estimated effects of 37.9% and 39.9%, respectively (both P < .001).

IN PRACTICE:

“These findings provide support that reduction of adding salt to foods may act as a potential behavioral intervention approach for preventing T2D. Future clinical trials are needed to further validate our findings,” the authors wrote.

SOURCE:

The study by Xuan Wang, MD, PhD, department of epidemiology, School of Public Health and Tropical Medicine, Tulane University, New Orleans, and colleagues was published in the November 2023 issue of Mayo Clinic Proceedings.

LIMITATIONS:

The researchers could not completely exclude the possibility that high frequency of adding salt to foods is a marker for an unhealthy lifestyle. Self-reported frequency of adding salt to food might be subject to information bias and did not provide quantitative information on total sodium intake. In addition, participants were mainly of European descent, making application of the findings to other ethnic groups unclear; the observational design meant researchers could not rule out residual confounding; and information on addition of salt to food was available only at baseline, so potential changes in salt consumption during follow-up could not be considered.

DISCLOSURES:

The study was supported by grants from the National Heart, Lung, and Blood Institute; the National Institute of Diabetes and Digestive and Kidney Diseases; the Fogarty International Center; and Tulane Research Centers of Excellence Awards. The authors reported no potential competing interests.

When topical treatment does not control atopic dermatitis (AD) in adults, a range of advanced treatments may improve outcomes and can be considered, according to new evidence-based guidelines from the American Academy of Dermatology (AAD)..

The guidelines cover approved and off-label uses of systemic therapies and phototherapy, including new treatments that have become available since the last guidelines were published almost a decade ago. These include biologics and oral Janus kinase (JAK) inhibitors, as well as older oral or injectable immunomodulators and antimetabolites, oral antibiotics, antihistamines, and phosphodiesterase-4 inhibitors. The guidelines rate the existing evidence as “strong” for dupilumab, tralokinumab, abrocitinib, baricitinib, and upadacitinib. They also conditionally recommend phototherapy, as well as cyclosporine, methotrexate, azathioprine, and mycophenolate, but recommend against the use of systemic corticosteroids.

The guidelines update the AAD’s 2014 recommendations for managing AD in adults with phototherapy and systemic therapies. “At that time, prednisone – universally agreed to be the least appropriate chronic therapy for AD – was the only Food and Drug Administration–approved agent,” Robert Sidbury, MD, MPH, who cochaired a 14-member multidisciplinary work group that assembled the guidelines, told this news organization. “This was the driver.”

The latest guidelines were published online in the Journal of the American Academy of Dermatology.
 

Broad evidence review

Dr. Sidbury, chief of the division of dermatology at Seattle Children’s Hospital, guidelines cochair Dawn M. R. Davis, MD, a dermatologist at the Mayo Clinic, Rochester, Minn., and colleagues conducted a systematic evidence review of phototherapy such as narrowband and broadband UVB and systemic therapies, including biologics such as dupilumab and tralokinumab, JAK inhibitors such as upadacitinib and abrocitinib, and immunosuppressants such as methotrexate and azathioprine.

Next, the work group applied the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach for assessing the certainty of the evidence and formulating and grading clinical recommendations based on relevant randomized trials in the medical literature.
 

Recommendations, future studies

Of the 11 evidence-based recommendations of therapies for adults with AD refractory to topical medications, the work group ranks 5 as “strong” based on the evidence and the rest as “conditional.” “Strong” implies the benefits clearly outweigh risks and burdens, they apply to most patients in most circumstances, and they fall under good clinical practice. “Conditional” means the benefits and risks are closely balanced for most patients, “but the appropriate action may different depending on the patient or other stakeholder values,” the authors wrote.

In their remarks about phototherapy, the work group noted that most published literature on the topic “reports on the efficacy and safety of narrow band UVB. Wherever possible, use a light source that minimizes the potential for harm under the supervision of a qualified clinician.”

In their remarks about cyclosporine, they noted that evidence suggests an initial dose of 3 mg/kg per day to 5 mg/kg per day is effective, but that the Food and Drug Administration has not approved cyclosporine for use in AD. “The FDA has approved limited-term use (up to 1 year) in psoriasis,” they wrote. “Comorbidities or drug interactions that may exacerbate toxicity make this intervention inappropriate for select patients.” The work group noted that significant research gaps remain in phototherapy, especially trials that compare different phototherapy modalities and those that compare phototherapy with other AD treatment strategies.

“Larger clinical trials would also be helpful for cyclosporine, methotrexate, azathioprine, and mycophenolate to improve the certainty of evidence for those medications,” they added. “Furthermore, formal cost-effectiveness analyses comparing older to newer treatments are needed.”

They recommended the inclusion of active comparator arms in randomized, controlled trials as new systemic therapies continue to be developed and tested.

The work group ranked the level of evidence they reviewed for the therapies from very low to moderate. No therapy was judged to have high evidence. They also cited the short duration of most randomized controlled trials of phototherapy.

Using the guidelines in clinical care

According to Dr. Davis, the topic of which agent if any should be considered “first line” generated robust discussion among the work group members.

“When there are not robust head-to-head trials – and there are not – it is often opinion that governs this decision, and opinion should not, when possible, govern a guideline,” Dr. Davis said. “Accordingly, we determined based upon the evidence agents – plural – that deserve to be considered ‘first line’ but not a single agent.”

In her opinion, the top three considerations regarding use of systemic therapy for AD relate to patient selection and shared decision making. One, standard therapy has failed. Two, diagnosis is assured. And three, “steroid phobia should be considered,” and patients should be “fully informed of risks and benefits of both treating and not treating,” she said.

Dr. Sidbury reported that he serves as an advisory board member for Pfizer, a principal investigator for Regeneron, an investigator for Brickell Biotech and Galderma USA, and a consultant for Galderma Global and Micreos. Dr. Davis reported having no relevant disclosures. Other work group members reported having financial disclosures with many pharmaceutical companies. The study was supported by internal funds from the American Academy of Dermatology.

Two, diagnosis is assured. And three, “steroid phobia should be considered,” and patients should be “fully informed of risks and benefits of both treating and not treating,” she said.

Dr. Sidbury reported that he serves as an advisory board member for Pfizer, a principal investigator for Regeneron, an investigator for Brickell Biotech and Galderma USA, and a consultant for Galderma Global and Micreos. Dr. Davis reported having no relevant disclosures. Other work group members reported having financial disclosures with many pharmaceutical companies. The study was supported by internal funds from the American Academy of Dermatology.

When topical treatment does not control atopic dermatitis (AD) in adults, a range of advanced treatments may improve outcomes and can be considered, according to new evidence-based guidelines from the American Academy of Dermatology (AAD)..

The guidelines cover approved and off-label uses of systemic therapies and phototherapy, including new treatments that have become available since the last guidelines were published almost a decade ago. These include biologics and oral Janus kinase (JAK) inhibitors, as well as older oral or injectable immunomodulators and antimetabolites, oral antibiotics, antihistamines, and phosphodiesterase-4 inhibitors. The guidelines rate the existing evidence as “strong” for dupilumab, tralokinumab, abrocitinib, baricitinib, and upadacitinib. They also conditionally recommend phototherapy, as well as cyclosporine, methotrexate, azathioprine, and mycophenolate, but recommend against the use of systemic corticosteroids.

The guidelines update the AAD’s 2014 recommendations for managing AD in adults with phototherapy and systemic therapies. “At that time, prednisone – universally agreed to be the least appropriate chronic therapy for AD – was the only Food and Drug Administration–approved agent,” Robert Sidbury, MD, MPH, who cochaired a 14-member multidisciplinary work group that assembled the guidelines, told this news organization. “This was the driver.”

The latest guidelines were published online in the Journal of the American Academy of Dermatology.
 

Broad evidence review

Dr. Sidbury, chief of the division of dermatology at Seattle Children’s Hospital, guidelines cochair Dawn M. R. Davis, MD, a dermatologist at the Mayo Clinic, Rochester, Minn., and colleagues conducted a systematic evidence review of phototherapy such as narrowband and broadband UVB and systemic therapies, including biologics such as dupilumab and tralokinumab, JAK inhibitors such as upadacitinib and abrocitinib, and immunosuppressants such as methotrexate and azathioprine.

Next, the work group applied the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach for assessing the certainty of the evidence and formulating and grading clinical recommendations based on relevant randomized trials in the medical literature.
 

Recommendations, future studies

Of the 11 evidence-based recommendations of therapies for adults with AD refractory to topical medications, the work group ranks 5 as “strong” based on the evidence and the rest as “conditional.” “Strong” implies the benefits clearly outweigh risks and burdens, they apply to most patients in most circumstances, and they fall under good clinical practice. “Conditional” means the benefits and risks are closely balanced for most patients, “but the appropriate action may different depending on the patient or other stakeholder values,” the authors wrote.

In their remarks about phototherapy, the work group noted that most published literature on the topic “reports on the efficacy and safety of narrow band UVB. Wherever possible, use a light source that minimizes the potential for harm under the supervision of a qualified clinician.”

In their remarks about cyclosporine, they noted that evidence suggests an initial dose of 3 mg/kg per day to 5 mg/kg per day is effective, but that the Food and Drug Administration has not approved cyclosporine for use in AD. “The FDA has approved limited-term use (up to 1 year) in psoriasis,” they wrote. “Comorbidities or drug interactions that may exacerbate toxicity make this intervention inappropriate for select patients.” The work group noted that significant research gaps remain in phototherapy, especially trials that compare different phototherapy modalities and those that compare phototherapy with other AD treatment strategies.

“Larger clinical trials would also be helpful for cyclosporine, methotrexate, azathioprine, and mycophenolate to improve the certainty of evidence for those medications,” they added. “Furthermore, formal cost-effectiveness analyses comparing older to newer treatments are needed.”

They recommended the inclusion of active comparator arms in randomized, controlled trials as new systemic therapies continue to be developed and tested.

The work group ranked the level of evidence they reviewed for the therapies from very low to moderate. No therapy was judged to have high evidence. They also cited the short duration of most randomized controlled trials of phototherapy.

Using the guidelines in clinical care

According to Dr. Davis, the topic of which agent if any should be considered “first line” generated robust discussion among the work group members.

“When there are not robust head-to-head trials – and there are not – it is often opinion that governs this decision, and opinion should not, when possible, govern a guideline,” Dr. Davis said. “Accordingly, we determined based upon the evidence agents – plural – that deserve to be considered ‘first line’ but not a single agent.”

It’s important for doctors to ask about erections. Not only do our patients and their partners care about them, but they are a marker for overall health. I mean it. Penis problems are very common and are an early sign that patients could have a cardiac event. Think about it: Clogging the arteries of the heart is called a heart attack; clogging the arteries to the penis is a penis attack, or as doctors like to call it, erectile dysfunction.

The arteries to the penis are only 1 mm in diameter. They develop plaque and clog the circulation long before the 3-mm cardiac arteries. So, it’s very important for primary care doctors to talk to their patients about erection health. And I’ll be honest: It’s easier to talk to patients about how lifestyle is affecting their penis health than it is to discuss how lifestyle affects longevity or prevents cancer. I get a lot of men to quit smoking because I tell them what it’s doing to their penises.

It can be challenging for doctors and patients to talk about penises. It doesn’t come naturally for many of us. If a 20-year-old comes in to my office with his 85-year-old grandfather and they both say their penises aren’t working, how do you figure out what’s going on? Do they even have the same thing wrong with them?

Here’s a fun and helpful tool that I use in my office. It’s called the Erection Hardness Score. It was developed around the time that Viagra came out, in 1998. It’s been game-changing for me to get patients more comfortable talking about their erection issues.

LA JOLLA, CALIF. – Twelve years ago, an international task force of the European Alliance of Associations for Rheumatology (EULAR) released recommendations regarding nomenclature in calcium pyrophosphate deposition disease (CPPD), aiming to standardize the way the condition is described. “Pseudogout” was out, and “acute CPP crystal arthritis” was in, and a confusing array of multi-named phenotypes gained specific labels.

Since 2011, the nomenclature guidelines have been cited hundreds of times, but a new report finds that the medical literature mostly hasn’t followed the recommendations. The findings were released at the annual research symposium of the Gout, Hyperuricemia, and Crystal Associated Disease Network (G-CAN), which is taking another stab at overhauling CPPD nomenclature.

“The objective is to uniform and standardize the labels of the disease, the disease elements, and the clinical states,” rheumatologist Charlotte Jauffret, MD, of the Catholic University of Lille (France), said in a presentation. CPPD is a widely underdiagnosed disease that’s worth the same efforts to standardize nomenclature as occurred in gout, she said.

As Dr. Jauffret explained, CPPD has a diversity of phenotypes in asymptomatic, acute, and chronic forms that pose challenges to diagnosis. “The same terms are used to depict different concepts, and some disease elements are depicted through different names,” she said.

Among other suggestions, the 2011 EULAR recommendations suggested that rheumatologists use the terms chronic CPP crystal inflammatory arthritis instead of “pseudo-rheumatoid arthritis,” osteoarthritis with CPPD, instead of “pseudo-osteoarthritis,” and severe joint degeneration instead of “pseudo-neuropathic joint disease.”

Later reports noted that terms such as CPPD and chondrocalcinosis are still wrongly used interchangeably and called for an international consensus on nomenclature, Dr. Jauffret said.

For the new report, Dr. Jauffret and colleagues examined 985 articles from 2000-2022. The guidelines were often not followed even after the release of the recommendations.

For example, 49% of relevant papers used the label “pseudogout” before 2011, and 43% did afterward. A total of 34% of relevant papers described CPPD as chondrocalcinosis prior to 2011, and 22% did afterward.

G-CAN’s next steps are to reach consensus on terminology through online and in-person meetings in 2024, Dr. Jauffret said.
 

Use of correct gout nomenclature labels improved

In a related presentation, rheumatologist Ellen Prendergast, MBChB, of Dunedin Hospital in New Zealand, reported the results of a newly published review of gout studies before and after G-CAN released consensus recommendations for gout nomenclature in 2019. “There has been improvement in the agreed labels in some areas, but there remains quite significant variability,” she said.

The review examined American College of Rheumatology and EULAR annual meeting abstracts: 596 from 2016-2017 and 392 from 2020-2021. Dr. Prendergast said researchers focused on abstracts instead of published studies in order to gain the most up-to-date understanding of nomenclature.

“Use of the agreed labels ‘urate’ and ‘gout flare’ increased between the two periods. There were 219 of 383 (57.2%) abstracts with the agreed label ‘urate’ in 2016-2017, compared with 164 of 232 (70.7%) in 2020-2021 (P = .001),” the researchers reported. “There were 60 of 175 (34.3%) abstracts with the agreed label ‘gout flare’ in 2016-2017, compared with 57 of 109 (52.3%) in 2020-2021 (P = .003).”

And the use of the term “chronic gout,” which the guidelines recommend against, fell from 29 of 596 (4.9%) abstracts in 2016-2017 to 8 of 392 (2.0%) abstracts in 2020-2021 (P = .02).

One author of the gout nomenclature study reports various consulting fees, speaker fees, or grants outside the submitted work. The other authors of the two studies report no disclosures.

Long COVID can exacerbate existing mental health disorders or cause new-onset psychiatric symptoms, but mental illness does not cause long COVID, experts say.

The consensus guidance statement on the assessment and treatment of mental health symptoms in patients with post-acute sequelae of SARS-CoV-2 infection (PASC), also known as long COVID, was published online in Physical Medicine and Rehabilitation, the journal of the American Academy of Physical Medicine and Rehabilitation (AAPM&R).

The statement was developed by a task force that included experts from physical medicine, neurology, neuropsychiatry, neuropsychology, rehabilitation psychology, and primary care. It is the eighth guidance statement on long COVID published by AAPM&R).

“Many of our patients have reported experiences in which their symptoms of long COVID have been dismissed either by loved ones in the community, or also amongst health care providers, and they’ve been told their symptoms are in their head or due to a mental health condition, but that’s simply not true,” Abby L. Cheng, MD, a physiatrist at Barnes Jewish Hospital in St. Louis and a coauthor of the new guidance, said in a press briefing.

“Long COVID is real, and mental health conditions do not cause long COVID,” Dr. Cheng added.
 

Millions of Americans affected

Anxiety and depression have been reported as the second and third most common symptoms of long COVID, according to the guidance statement.

There is some evidence that the body’s inflammatory response – specifically, circulating cytokines – may contribute to the worsening of mental health symptoms or may bring on new symptoms of anxiety or depression, said Dr. Cheng. Cytokines may also affect levels of brain chemicals, such as serotonin, she said.

Researchers are also exploring whether the persistence of virus in the body, miniature blood clots in the body and brain, and changes to the gut microbiome affect the mental health of people with long COVID.

Some mental health symptoms – such as fatigue, brain fog, sleep disturbances, and tachycardia – can mimic long COVID symptoms, said Dr. Cheng.

The treatment is the same for someone with or without long COVID who has anxiety, depression, posttraumatic stress disorder, or other mental health conditions and includes treatment of coexisting medical conditions, supportive therapy and cognitive-behavioral therapy, and pharmacologic interventions, she said.

“Group therapy may have a particular role in the long COVID population because it really provides that social connection and awareness of additional resources in addition to validation of their experiences,” Dr. Cheng said.

The guidance suggests that primary care practitioners – if it’s within their comfort zone and they have the training – can be the first line for managing mental health symptoms.

But for patients whose symptoms are interfering with functioning and their ability to interact with the community, the guidance urges primary care clinicians to refer the patient to a specialist.

“It leaves the door open to them to practice within their scope but also gives guidance as to how, why, and who should be referred to the next level of care,” said Dr. Cheng.

Coauthor Monica Verduzco-Gutierrez, MD, chair of rehabilitation medicine at UT Health San Antonio, Texas, said that although fewer people are now getting long COVID, “it’s still an impactful number.”

The Centers for Disease Control and Prevention recently estimated that about 7% of American adults (18 million) and 1.3% of children had experienced long COVID.

Dr. Gutierrez said that it’s an evolving number, as some patients who have a second or third or fourth SARS-CoV-2 infection experience exacerbations of previous bouts of long COVID or develop long COVID for the first time.

“We are still getting new patients on a regular basis with long COVID,” said AAPM&R President Steven R. Flanagan, MD, a physical medicine specialist.

“This is a problem that really is not going away. It is still real and still ever-present,” said Dr. Flanagan, chair of rehabilitation medicine at NYU Langone Health.

But for patients whose symptoms are interfering with functioning and their ability to interact with the community, the guidance urges primary care clinicians to refer the patient to a specialist.

“It leaves the door open to them to practice within their scope but also gives guidance as to how, why, and who should be referred to the next level of care,” said Dr. Cheng.

Coauthor Monica Verduzco-Gutierrez, MD, chair of rehabilitation medicine at UT Health San Antonio, Texas, said that although fewer people are now getting long COVID, “it’s still an impactful number.”

The Centers for Disease Control and Prevention recently estimated that about 7% of American adults (18 million) and 1.3% of children had experienced long COVID.

Dr. Gutierrez said that it’s an evolving number, as some patients who have a second or third or fourth SARS-CoV-2 infection experience exacerbations of previous bouts of long COVID or develop long COVID for the first time.

“We are still getting new patients on a regular basis with long COVID,” said AAPM&R President Steven R. Flanagan, MD, a physical medicine specialist.

“This is a problem that really is not going away. It is still real and still ever-present,” said Dr. Flanagan, chair of rehabilitation medicine at NYU Langone Health.

Final results of the SELECT trial have shown that the antiobesity drug semaglutide (Wegovy) produced a consistent reduction of around 20% versus placebo across major cardiovascular event endpoints over the approximately 3-year follow-up in patients with overweight or obesity and cardiovascular disease but not diabetes.

“This is a very exciting set of results. I think it is going to have a big impact on a large number of people,” lead investigator A. Michael Lincoff, MD, vice chair for research in the department of cardiovascular medicine at the Cleveland Clinic, said in an interview. 

“And from a scientific standpoint, these data show that we now have a new pathway or a new modifiable risk factor for cardiovascular disease that we can use in our patients who have overweight or obesity,” he added.

The trial involved 17,604 patients with a history of cardiovascular disease and a body mass index of 27 kg/m² or above (mean BMI was 33), who were randomly assigned to the glucagonlike peptide–1 (GLP-1) agonist semaglutide, given by subcutaneous injection once weekly at a gradually escalating dose up to 2.4 mg daily by week 16, or placebo. The mean baseline glycated hemoglobin level was 5.8% and 66.4% of patients met the criteria for prediabetes.

Patients lost a mean of 9.4% of body weight over the first 2 years with semaglutide versus 0.88% with placebo.

The primary cardiovascular endpoint – a composite of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke – was reduced significantly, with a hazard ratio of 0.80 (95% confidence interval, 0.72-0.90; P < .001).  

Death from cardiovascular causes, the first confirmatory secondary endpoint, showed a 15% reduction (HR, 0.85; P = .07) but this missed meeting criteria for statistical significance, and because of the hierarchical design of the trial, this meant that superiority testing was not performed for the remaining confirmatory secondary endpoints.

However, results showed reductions of around 20% for the heart failure composite endpoint and for all-cause mortality, with confidence intervals that did not cross 1.0, and directionally consistent effects were observed for all supportive secondary endpoints.

The HR for the heart failure composite endpoint was 0.82 (95% CI, 0.71-0.96), and the HR for death from any cause was 0.81 (95% CI, 0.71-0.93). Nonfatal MI was reduced by 28% (HR 0.72; 95% CI, 0.61-0.85).

The effects of semaglutide on the primary endpoint appeared to be similar across all prespecified subgroups.

Adverse events leading to discontinuation of treatment occurred in 16.6% in the semaglutide group, mostly gastrointestinal effects, and in 8.2% in the placebo group.

The trial results were presented by Dr. Lincoff at the annual scientific sessions of the American Heart Association . They were also simultaneously published online in the New England Journal of Medicine.

Dr. Lincoff explained that there is a growing pandemic of overweight and obesity worldwide with clear evidence for years that these conditions increase the risk of cardiovascular events – and yet there has been no evidence, until now, that any pharmacologic or lifestyle therapy can reduce the increased risk conferred by overweight/obesity. 

“Patients in the trial were already taking standard of care therapies for other risk factors, such as hypertension and cholesterol, so this drug is giving additional benefit,” he said.

Dr. Lincoff believes these data will lead to a large increase in use of semaglutide, which is already available for the treatment of obesity and diabetes but can be difficult to get reimbursed.

“There is a lot of difficulty getting payors to pay for this drug for weight management. But with this new data from the SELECT trial there should be more willingness – at least in the population with a history of cardiovascular disease,” he commented. In diabetes, where it is already established that there is a cardiovascular risk reduction, it is easier to get these drugs reimbursed, he noted.

On the outcome data, Dr. Lincoff said he could not explain why cardiovascular death was not significantly reduced while all-cause mortality appeared to be cut more definitively.

“The cardiovascular death curves separated, then merged, then separated again. We don’t really know what is going on there. It may be that some deaths were misclassified. This trial was conducted through the COVID era and there may have been less information available on some patients because of that.”

But he added: “The all-cause mortality is more reassuring, as it doesn’t depend on classifying cause of death. Because of the design of the trial, we can’t formally claim a reduction in all-cause mortality, but the results do suggest there is an effect on this endpoint. And all the different types of cardiovascular events were similarly reduced in a consistent way, with similar effects seen across all subgroups. That is very reassuring.”
 

‘A new era’ for patients with obesity

Outside experts in the field were also impressed with the data.

Designated discussant of the trial at the AHA meeting, Ania Jastreboff, MD, associate professor medicine (endocrinology) at Yale University, New Haven, Conn., said the SELECT trial was “a turning point in the treatment of obesity and a call to action.

“Now is the time to treat obesity to improve health outcomes in people with cardiovascular disease,” she said.

Dr. Jastreboff noted that high BMI was estimated to have accounted for 4 million deaths worldwide in 2015, two-thirds of which were caused by cardiovascular disease. And she presented data showing that U.S. individuals meeting the SELECT criteria increased from 4.3 million in 2011-12 to 6.6 million in 2017-18.

She highlighted one major limitation of the SELECT trial: it enrolled a low number of women (38%) and ethnic minorities, with only 12% of the trial population being Black.

Deepak L. Bhatt, MD, director of Mount Sinai Fuster Heart Hospital, New York, described the SELECT results as “altogether a compelling package of data.”

“These results are even better than I had expected,” Dr. Bhatt said in an interview. “There is a significant reduction in MI as I had anticipated, but additionally, there is a reduction in all-cause death. One can debate the statistics, though on a common-sense level, I think it is a real finding,” he noted.

“Given that MI, heart failure, nephropathy, and revascularization are all reduced, and even stroke is numerically lower, it makes sense that all-cause mortality would be reduced,” he said. “To me, apart from the GI side effects, this counts as a home run.”

Steve Nissen, MD, chief academic officer at the Cleveland Clinic’s Heart, Vascular and Thoracic Institute, was similarly upbeat.

“These data prove what many of us have long suspected – that losing weight can reduce cardiovascular morbidity and mortality. This is great news for patients living with obesity. The obesity epidemic is out of control,” he added. “We need to have therapies that improve cardiovascular outcomes caused by obesity and this shows that semaglutide can do that. I think this is the beginning of a whole new era for patients with obesity.”

Michelle O’Donoghue, MD, associate professor of medicine at Harvard Medical School, Boston, called the results of SELECT “both intriguing and compelling. Certainly, these findings lend further support to the use of semaglutide in a much broader secondary prevention population of individuals with obesity.”

Christie Ballantyne, MD, director of the center for cardiometabolic disease prevention at Baylor College of Medicine, Houston, described the SELECT study as “a landmark trial which will change the practice of medicine in regard to how we treat obesity.”

He compared it with the landmark 4S trial in 1994, the first study in the area of cholesterol lowering therapy to show a clear benefit in reducing cardiovascular events and total mortality, and “began a drastic change in the way that physicians approached treatment of cholesterol.”

On the more robust reduction in all-cause death, compared with cardiovascular death,

Dr. Ballantyne pointed out: “Adjudication of dead or alive is something that everyone gets right. In contrast, the cause of death is sometime difficult to ascertain. Most importantly, the benefit on total mortality also provides assurance that this therapy does not have some adverse effect on increasing noncardiovascular deaths.”
 

Gastrointestinal adverse effects

On the side effects seen with semaglutide, Dr. Lincoff reported that 10% of patients in the semaglutide group discontinued treatment because of GI side effects versus 2% in the placebo arm. He said this was “an expected issue.”

“GI effects, such as nausea, vomiting and diarrhea, are known side effects of this whole class of drugs. The dose is slowly escalated to manage these adverse effects but there will be a proportion of patients who can’t tolerate it, although the vast majority are able to continue.”

He noted that, while dose reduction was allowed, of the patients who were still on the drug at 2 years, 77% were on the full dose, and 23% were on a reduced dose.

Dr. Lincoff pointed out that there were no serious adverse events with semaglutide. “This is the largest database by far now on the drug with a long-term follow up and we didn’t see the emergence of any new safety signals, which is very reassuring.”  

Dr. Nissen said the 16% rate of patients stopping the drug because of tolerability “is not a trivial number.”

He noted that the semaglutide dose used in this study was larger than that used in diabetes.

“They did this to try to achieve more weight loss but then you get more issues with tolerability. It’s a trade-off. If patients are experiencing adverse effects, the dose can be reduced, but then you will lose some effect. All the GLP-1 agonists have GI side effects – it’s part of the way that they work.”
 

Just weight loss or other actions too?

Speculating on the mechanism behind the reduction in cardiovascular events with semaglutide, Dr. Lincoff does not think it is just weight reduction.

“The event curves start to diverge very soon after the start of the trial and yet the maximum weight loss doesn’t occur until about 65 weeks. I think something else is going on.”

In the paper, the researchers noted that GLP-1 agonists have been shown in animal studies to reduce inflammation, improve endothelial and left ventricular function, promote plaque stability, and decrease platelet aggregation. In this trial, semaglutide was associated with changes in multiple biomarkers of cardiovascular risk, including blood pressure, waist circumference, glycemic control, nephropathy, and levels of lipids and C-reactive protein.

Dr. Lincoff also pointed out that similar benefits were seen in patients with different levels of overweight, and in those who were prediabetic and those who weren’t, so benefit was not dependent on baseline BMI or glycated hemoglobin levels.

Dr. O’Donoghue agreed that other effects, as well as weight loss, could be involved. “The reduction in events with semaglutide appeared very early after initiation and far preceded the drug’s maximal effects on weight reduction. This might suggest that the drug offers other cardioprotective effects through pathways independent of weight loss. Certainly, semaglutide and the other GLP-1 agonists appear to attenuate inflammation, and the patterns of redistribution of adipose tissue may also be of interest.”

She also pointed out that the reduction in cardiovascular events appeared even earlier in this population of obese nondiabetic patients with cardiovascular disease than in prior studies of patients with diabetes. “It may suggest that there is particular benefit for this type of therapy in patients with an inflammatory milieu. I look forward to seeing further analyses to help tease apart the correlation between changes in inflammation, observed weight loss and cardiovascular benefit.”
 

Effect on clinical practice

With the majority of patients with cardiovascular disease being overweight, these results are obviously going to increase demand for semaglutide, but cost and availability are going to be an issue.

Dr. Bhatt noted that semaglutide is already very popular. “Weight loss drugs are somewhat different from other medications. I can spend 30 minutes trying to convince a patient to take a statin, but here people realize it’s going to cause weight loss and they come in asking for it even if they don’t strictly need it. I think it’s good to have cardiovascular outcome data because now at least for this population of patients, we have evidence to prescribe it.”

He agreed with Dr. Lincoff that these new data should encourage insurance companies to cover the drug, because in reducing cardiovascular events it should also improve downstream health care costs.

“It is providing clear cardiovascular and kidney benefit, so it is in the best interest to the health care system to fund this drug,” he said. “I hope insurers look at it rationally in this way, but they may also be frightened of the explosion of patients wanting this drug and now doctors wanting to prescribe it and how that would affect their shorter-term costs.”

Dr. Lincoff said it would not be easy to prioritize certain groups. “We couldn’t identify any subgroup who showed particularly more benefit than any others. But in the evolution of any therapy, there is a time period where it is in short supply and prohibitively expensive, then over time when there is some competition and pricing deals occur as more people are advocating for it, they become more available.”
 

‘A welcome treatment option’

In an editorial accompanying publication of the trial, Amit Khera, MD, University of Texas Southwestern Medical Center, Dallas, and Tiffany Powell-Wiley, MD, MPH, National Institutes of Health, Bethesda, noted that baseline risk factors such as LDL cholesterol (78 mg/dL) and systolic blood pressure (131 mm Hg) were not ideal in the semaglutide group in this trial, and they suggest that the benefits of semaglutide may be attenuated when these measures are better controlled.

But given that more than 20 million people in the United States have coronary artery disease, with the majority having overweight or obesity and only approximately 30% having concomitant diabetes, they said that, even in the context of well-controlled risk factors and very low LDL cholesterol levels, the residual risk of atherosclerotic cardiovascular disease in these persons is unacceptably high. “Thus, the SELECT trial provides a welcome treatment option that can be extended to millions of additional patients.”

However, the editorialists cautioned that semaglutide at current pricing comes with a significant cost to both patients and society, which makes this treatment inaccessible for many. 

They added that intensive lifestyle interventions and bariatric surgery remain effective but underutilized options for obesity, and that the prevention of obesity before it develops should be the primary goal.

The SELECT trial was supported by Novo Nordisk, and several coauthors are employees of the company. Dr. Lincoff is a consultant for Novo Nordisk. Dr. Bhatt and Dr. Nissen are involved in a cardiovascular outcomes trial with a new investigational weight loss drug from Lilly. Dr. Bhatt and Dr. Ballantyne are also investigators in a Novo Nordisk trial of a new anti-inflammatory drug.

Final results of the SELECT trial have shown that the antiobesity drug semaglutide (Wegovy) produced a consistent reduction of around 20% versus placebo across major cardiovascular event endpoints over the approximately 3-year follow-up in patients with overweight or obesity and cardiovascular disease but not diabetes.

On the outcome data, Dr. Lincoff said he could not explain why cardiovascular death was not significantly reduced while all-cause mortality appeared to be cut more definitively.

“The cardiovascular death curves separated, then merged, then separated again. We don’t really know what is going on there. It may be that some deaths were misclassified. This trial was conducted through the COVID era and there may have been less information available on some patients because of that.”

But he added: “The all-cause mortality is more reassuring, as it doesn’t depend on classifying cause of death. Because of the design of the trial, we can’t formally claim a reduction in all-cause mortality, but the results do suggest there is an effect on this endpoint. And all the different types of cardiovascular events were similarly reduced in a consistent way, with similar effects seen across all subgroups. That is very reassuring.”
 

‘A new era’ for patients with obesity

Outside experts in the field were also impressed with the data.

Designated discussant of the trial at the AHA meeting, Ania Jastreboff, MD, associate professor medicine (endocrinology) at Yale University, New Haven, Conn., said the SELECT trial was “a turning point in the treatment of obesity and a call to action.

“Now is the time to treat obesity to improve health outcomes in people with cardiovascular disease,” she said.

Dr. Jastreboff noted that high BMI was estimated to have accounted for 4 million deaths worldwide in 2015, two-thirds of which were caused by cardiovascular disease. And she presented data showing that U.S. individuals meeting the SELECT criteria increased from 4.3 million in 2011-12 to 6.6 million in 2017-18.

She highlighted one major limitation of the SELECT trial: it enrolled a low number of women (38%) and ethnic minorities, with only 12% of the trial population being Black.

Deepak L. Bhatt, MD, director of Mount Sinai Fuster Heart Hospital, New York, described the SELECT results as “altogether a compelling package of data.”

“These results are even better than I had expected,” Dr. Bhatt said in an interview. “There is a significant reduction in MI as I had anticipated, but additionally, there is a reduction in all-cause death. One can debate the statistics, though on a common-sense level, I think it is a real finding,” he noted.

“Given that MI, heart failure, nephropathy, and revascularization are all reduced, and even stroke is numerically lower, it makes sense that all-cause mortality would be reduced,” he said. “To me, apart from the GI side effects, this counts as a home run.”

Steve Nissen, MD, chief academic officer at the Cleveland Clinic’s Heart, Vascular and Thoracic Institute, was similarly upbeat.

“These data prove what many of us have long suspected – that losing weight can reduce cardiovascular morbidity and mortality. This is great news for patients living with obesity. The obesity epidemic is out of control,” he added. “We need to have therapies that improve cardiovascular outcomes caused by obesity and this shows that semaglutide can do that. I think this is the beginning of a whole new era for patients with obesity.”

Michelle O’Donoghue, MD, associate professor of medicine at Harvard Medical School, Boston, called the results of SELECT “both intriguing and compelling. Certainly, these findings lend further support to the use of semaglutide in a much broader secondary prevention population of individuals with obesity.”

Christie Ballantyne, MD, director of the center for cardiometabolic disease prevention at Baylor College of Medicine, Houston, described the SELECT study as “a landmark trial which will change the practice of medicine in regard to how we treat obesity.”

He compared it with the landmark 4S trial in 1994, the first study in the area of cholesterol lowering therapy to show a clear benefit in reducing cardiovascular events and total mortality, and “began a drastic change in the way that physicians approached treatment of cholesterol.”

On the more robust reduction in all-cause death, compared with cardiovascular death,

Dr. Ballantyne pointed out: “Adjudication of dead or alive is something that everyone gets right. In contrast, the cause of death is sometime difficult to ascertain. Most importantly, the benefit on total mortality also provides assurance that this therapy does not have some adverse effect on increasing noncardiovascular deaths.”
 

Gastrointestinal adverse effects

On the side effects seen with semaglutide, Dr. Lincoff reported that 10% of patients in the semaglutide group discontinued treatment because of GI side effects versus 2% in the placebo arm. He said this was “an expected issue.”

“GI effects, such as nausea, vomiting and diarrhea, are known side effects of this whole class of drugs. The dose is slowly escalated to manage these adverse effects but there will be a proportion of patients who can’t tolerate it, although the vast majority are able to continue.”

He noted that, while dose reduction was allowed, of the patients who were still on the drug at 2 years, 77% were on the full dose, and 23% were on a reduced dose.

Dr. Lincoff pointed out that there were no serious adverse events with semaglutide. “This is the largest database by far now on the drug with a long-term follow up and we didn’t see the emergence of any new safety signals, which is very reassuring.”  

Dr. Nissen said the 16% rate of patients stopping the drug because of tolerability “is not a trivial number.”

He noted that the semaglutide dose used in this study was larger than that used in diabetes.

“They did this to try to achieve more weight loss but then you get more issues with tolerability. It’s a trade-off. If patients are experiencing adverse effects, the dose can be reduced, but then you will lose some effect. All the GLP-1 agonists have GI side effects – it’s part of the way that they work.”
 

Just weight loss or other actions too?

Speculating on the mechanism behind the reduction in cardiovascular events with semaglutide, Dr. Lincoff does not think it is just weight reduction.

“The event curves start to diverge very soon after the start of the trial and yet the maximum weight loss doesn’t occur until about 65 weeks. I think something else is going on.”

In the paper, the researchers noted that GLP-1 agonists have been shown in animal studies to reduce inflammation, improve endothelial and left ventricular function, promote plaque stability, and decrease platelet aggregation. In this trial, semaglutide was associated with changes in multiple biomarkers of cardiovascular risk, including blood pressure, waist circumference, glycemic control, nephropathy, and levels of lipids and C-reactive protein.

Dr. Lincoff also pointed out that similar benefits were seen in patients with different levels of overweight, and in those who were prediabetic and those who weren’t, so benefit was not dependent on baseline BMI or glycated hemoglobin levels.

Dr. O’Donoghue agreed that other effects, as well as weight loss, could be involved. “The reduction in events with semaglutide appeared very early after initiation and far preceded the drug’s maximal effects on weight reduction. This might suggest that the drug offers other cardioprotective effects through pathways independent of weight loss. Certainly, semaglutide and the other GLP-1 agonists appear to attenuate inflammation, and the patterns of redistribution of adipose tissue may also be of interest.”

She also pointed out that the reduction in cardiovascular events appeared even earlier in this population of obese nondiabetic patients with cardiovascular disease than in prior studies of patients with diabetes. “It may suggest that there is particular benefit for this type of therapy in patients with an inflammatory milieu. I look forward to seeing further analyses to help tease apart the correlation between changes in inflammation, observed weight loss and cardiovascular benefit.”
 

Effect on clinical practice

With the majority of patients with cardiovascular disease being overweight, these results are obviously going to increase demand for semaglutide, but cost and availability are going to be an issue.

Dr. Bhatt noted that semaglutide is already very popular. “Weight loss drugs are somewhat different from other medications. I can spend 30 minutes trying to convince a patient to take a statin, but here people realize it’s going to cause weight loss and they come in asking for it even if they don’t strictly need it. I think it’s good to have cardiovascular outcome data because now at least for this population of patients, we have evidence to prescribe it.”

He agreed with Dr. Lincoff that these new data should encourage insurance companies to cover the drug, because in reducing cardiovascular events it should also improve downstream health care costs.

“It is providing clear cardiovascular and kidney benefit, so it is in the best interest to the health care system to fund this drug,” he said. “I hope insurers look at it rationally in this way, but they may also be frightened of the explosion of patients wanting this drug and now doctors wanting to prescribe it and how that would affect their shorter-term costs.”

Dr. Lincoff said it would not be easy to prioritize certain groups. “We couldn’t identify any subgroup who showed particularly more benefit than any others. But in the evolution of any therapy, there is a time period where it is in short supply and prohibitively expensive, then over time when there is some competition and pricing deals occur as more people are advocating for it, they become more available.”
 

‘A welcome treatment option’

In an editorial accompanying publication of the trial, Amit Khera, MD, University of Texas Southwestern Medical Center, Dallas, and Tiffany Powell-Wiley, MD, MPH, National Institutes of Health, Bethesda, noted that baseline risk factors such as LDL cholesterol (78 mg/dL) and systolic blood pressure (131 mm Hg) were not ideal in the semaglutide group in this trial, and they suggest that the benefits of semaglutide may be attenuated when these measures are better controlled.

But given that more than 20 million people in the United States have coronary artery disease, with the majority having overweight or obesity and only approximately 30% having concomitant diabetes, they said that, even in the context of well-controlled risk factors and very low LDL cholesterol levels, the residual risk of atherosclerotic cardiovascular disease in these persons is unacceptably high. “Thus, the SELECT trial provides a welcome treatment option that can be extended to millions of additional patients.”

However, the editorialists cautioned that semaglutide at current pricing comes with a significant cost to both patients and society, which makes this treatment inaccessible for many. 

They added that intensive lifestyle interventions and bariatric surgery remain effective but underutilized options for obesity, and that the prevention of obesity before it develops should be the primary goal.

The SELECT trial was supported by Novo Nordisk, and several coauthors are employees of the company. Dr. Lincoff is a consultant for Novo Nordisk. Dr. Bhatt and Dr. Nissen are involved in a cardiovascular outcomes trial with a new investigational weight loss drug from Lilly. Dr. Bhatt and Dr. Ballantyne are also investigators in a Novo Nordisk trial of a new anti-inflammatory drug.

Two biomarkers – pregnancy-associated plasma protein A2 (PAPP-A2) and activin A – when added to relevant clinical information have a better positive predictive value than and a comparable negative predictive value to the currently used ratio of soluble fms-like tyrosine kinase 1 (sFlt-1) to placental growth factor (PlGF), new research suggests.

The third-trimester sFlt-1:PlGF ratio can predict short-term absence of preeclampsia. By contrast, PAPP-A2 and activin A could serve as biomarkers to predict the occurrence as well as the absence of preeclampsia, according to the authors.

Preeclampsia has “potentially devastating maternal and fetal complications, [including] significantly increased cardiovascular risk for affected women later in life,” study author Stella S. Daskalopoulou, MD, PhD, associate professor of medicine at McGill University Health Centre in Montreal, said in an interview.

“A more accurate prediction of preeclampsia is expected to improve risk stratification and clinical care and shape clinical practice guidelines,” she said.

The study was published online in the Canadian Journal of Cardiology.
 

Better predictive value

For a prospective cohort study, the investigators recruited 192 women with first-trimester high-risk singleton pregnancies from tertiary obstetric clinics in Montreal.

At baseline, they collected clinical information, including height, prepregnancy weight, personal and family medical history, and medication use.

At each trimester, blood pressure was measured, and blood samples were collected to quantify sFlt-1, PlGF, PAPP-A2, PAPP-A, activin A, inhibin A, follistatin, and glycosylated fibronectin. For the sFlt-1:PlGF ratio, the researchers used a cutoff point of 38, based on prior evidence. Because there are no agreed-upon cutoff points for the other biomarkers, they chose cutoff points that maximized sensitivity and specificity.

Pregnancies were considered high risk if the mother had any of the following conditions: prepregnancy BMI ≥ 25, maternal age ≥ 35 years, chronic hypertension, diabetes, renal disease, conception via in vitro fertilization, or maternal or first-degree family history of preeclampsia.

The primary outcome was preeclampsia, which was defined according to the Society of Obstetrics and Gynecology guidelines as systolic blood pressure ≥ 140 mm Hg or diastolic blood pressure of ≥ mm Hg together with either proteinuria or maternal end-organ dysfunction.

A total of 18 women (9.38%) developed preeclampsia. Those women had higher blood pressure at baseline (although it was within normal limits) and were more likely to have preexisting diabetes or a previous pregnancy with preeclampsia. They were also more likely to report Black race. Serum levels of PAPP-A, PAPP-A2, activin A, and inhibin A were significantly different between patients who developed preeclampsia and those who did not. These levels were increased throughout pregnancy.

Alongside the sFlt-1:PlGF ratio, two biomarkers, PAPP-A2 (odds ratio, 1.78) and activin A (OR, 1.84), were significantly associated with the primary outcome after adjustment for age, prepregnancy BMI, race, and mean arterial pressure.

When added to a model that included those clinical factors, a positive third-trimester result for both PAPP-A2 and activin A had a better positive predictive value than the sFlt-1:PlGF ratio added to the clinical model (91.67% vs. 66.67%). The two biomarkers also had a negative predictive value that was comparable to that of the sFlt-1:PlGF ratio (97.69% vs. 96%).

Study limitations include the small sample size and missing covariates for some participants. Furthermore, the findings cannot be generalized to low-risk populations.

“Whereas the third-trimester sFlt-1:PlGF ratio can predict short-term absence of preeclampsia, PAPP-A2 and activin A had both high positive and negative predictive values and thus could serve as biomarkers to predict the occurrence (and absence) of preeclampsia; these findings will be validated in future studies,” the authors concluded.

Dr. Daskalopoulou said that her group is currently performing a large multinational study, PULSE, “which will be the ideal platform to validate and extend our findings. The aim of the study is to predict preeclampsia using a multimodal approach that includes arterial stiffness measurements and blood biomarkers.”

She expanded on the potential benefits of this research. “Finding an accurate predictive tool would not only help design appropriate early care plans for truly high-risk pregnant women, including monitoring and delivery planning, but also facilitate the development of novel strategies for the prevention and treatment of preeclampsia, improving the life of millions of young mothers and their offspring around the world.”
 

Promising biomarkers

Commenting on the study, Nieca Goldberg, MD, clinical associate professor of medicine at NYU Langone Health and medical director of Atria, both in New York, said, “These biomarkers are promising, as the current biomarker, sFlt-1:PlGF, is good at ruling out preeclampsia in the short term, while the new biomarkers show that they are better at ruling in preeclampsia” as well as ruling it out. Dr. Goldberg was not involved in the research.

“The current study is small, some participant data points are missing, and the researchers only studied high-risk pregnancies,” she added. “We need larger studies of all the risk markers, in both high- and low-risk pregnancies that are followed throughout pregnancy.”

NEW YORK – As a result of recent progress in the control of prurigo nodularis, failure to recognize the differences in presentation across skin types threatens prolonged but preventable morbidity from a disease with a devastating clinical impact, according to an expert evaluating current approaches at the Skin of Color Update 2023.

“As dermatologists, prurigo nodularis is one of the most severe diseases we treat, said Shawn G. Kwatra, MD, director of the Johns Hopkins Itch Center, Baltimore. Now with one approved therapy and more coming, “it offers one of the most important opportunities we have to dramatically improve someone’s entire life.”

Ted Bosworth/MDedge News

Prior to the September 2022 approval of dupilumab for the treatment of prurigo nodularis (the first treatment approved for this indication), Dr. Kwatra said that the limited options for control of pruritus made him anxious. Prurigo nodularis is characterized by highly itchy nodules that can produce symptoms patients describe as unbearable.
 

Itch typically severe

On a scale for which 10 represents the worst itch imaginable, scores of 8 or greater are not unusual, according to Dr. Kwatra. Nodules on the trunk and the extensor surfaces of the arms and legs are characteristic, but the persistent itch is the immediate target of treatment once the diagnosis is made. For that reason, he urged clinicians to be familiar with the presentation in patients with darker skin types to reduce time to treatment.

In addition to the difficulty of seeing the characteristic red that is typical of erythema in lighter skin, patients with darker skin types tend to have larger nodules that might vary in shape relative to lighter skin types, Dr. Kwatra said. Given that the presentation of prurigo nodularis is highly heterogeneous even among the same skin types, the nuances in patients with darker skin can be that much more confusing for those without prior experience.

Among Blacks in particular, the nodules in some cases “can be huge,” he added. “They can almost look like keloids due to their thickened and fibrotic appearance.”
 

Phenotypes appear to be racially linked

In Black patients, the appearance can vary enough relative to lighter skin individuals, that “there seems to be something a little bit different going on,” he said, and this is, in fact, supported by a cluster analysis of circulating biomarkers reported by Dr. Kwatra and colleagues in 2022, in the Journal of Investigative Dermatology.

In that study, the biomarker profile distinguished two distinct groups. Whites were more common in a cluster with relatively low expression of inflammatory markers (cluster 1), while Blacks were more common in a cluster with an inflammatory plasma profile (cluster 2), with higher relative expression of multiple cytokines, C-reactive protein, eosinophils, and other markers of up-regulated inflammation.

In addition to a lower rate of myelopathy in cluster 2 than cluster 1 (18% vs. 67%; P = .028), patients in cluster 2 had a significantly worse itch than those in cluster 1 on the Numeric Rating Scale for itch and a significantly lower quality of life based on the Dermatology Life Quality Index score.

Other work at Dr. Kwatra’s center that is based on genetic sequencing has provided evidence that Blacks – and Asians to a lesser extent – are predisposed genetically to develop nodules, perhaps explaining why the nodules tend to be larger than those seen in Whites.

The significance of the evidence that prurigo nodularis is associated with a more up-regulated inflammatory profile in Blacks than in Whites is that they might be particularly likely to respond to dupilumab or other targeted immunomodulating therapies that are in development, according to Dr. Kwatra. Although he did not provide data on response by race, he did provide several case examples of complete itch control following dupilumab therapy in Black patients.

In his experience, high levels of blood eosinophils and other inflammatory markers are predictors of response to dupilumab regardless of skin type, but he expressed concern that time to diagnosis is sometimes longer in Black patients if the nuances of disease expression are not appreciated.

For treating prurigo nodularis in Blacks as well as Whites, Dr. Kwatra suggested that clinicians stay current with what he predicted will be a growing array of treatment options. He did not discuss nemolizumab, an interleukin-31 receptor alpha antagonist. Soon after the meeting, results of a phase 3 trial of nemolizumab in patients with moderate to severe prurigo nodularis were published in the New England Journal of Medicine. (Dr. Kwatra is the lead author of the study but did not specifically discuss this treatment at the meeting.)

In the international placebo-controlled trial, called OLYMPIA 2, treatment was associated with a significant reduction in the signs and symptoms of prurigo nodularis, including reductions in itch, at 16 weeks, although only 4% of patients in the study were Black.

Given the expanding array of therapies, the message of considering prurigo nodularis in Black patients in order to accelerate the time to diagnosis is timely, Andrew F. Alexis, MD, MPH, professor of clinical dermatology and vice-chair for diversity and inclusion for the department of dermatology, Weill Cornell Medicine, New York.

“Current studies suggest a higher prevalence and greater severity of prurigo nodularis among Black patients compared to White patients,” said Dr. Alexis, agreeing with Dr. Kwatra. Referring to evidence that Blacks might mount a greater inflammatory response to prurigo nodularis than Whites, Dr. Alexis called for “a better understanding of the pathomechanisms” of this disease in order “to address unmet needs and reduce disparities for our diverse population of patients who suffer from prurigo nodularis.’

Dr. Kwatra reported financial relationships with AbbVie, Amgen, Arcutis, ASLAN, Cara, Castle Biosciences, Celldex, Galderma, Incyte, Johnson & Johnson, LEO pharma, Novartis, Pfizer, Regeneron, and Sanofi.

Nodules on the trunk and the extensor surfaces of the arms and legs are characteristic, but the persistent itch is the immediate target of treatment once the diagnosis is made. For that reason, he urged clinicians to be familiar with the presentation in patients with darker skin types to reduce time to treatment.

In addition to the difficulty of seeing the characteristic red that is typical of erythema in lighter skin, patients with darker skin types tend to have larger nodules that might vary in shape relative to lighter skin types, Dr. Kwatra said. Given that the presentation of prurigo nodularis is highly heterogeneous even among the same skin types, the nuances in patients with darker skin can be that much more confusing for those without prior experience.

Among Blacks in particular, the nodules in some cases “can be huge,” he added. “They can almost look like keloids due to their thickened and fibrotic appearance.”
 

Phenotypes appear to be racially linked

In Black patients, the appearance can vary enough relative to lighter skin individuals, that “there seems to be something a little bit different going on,” he said, and this is, in fact, supported by a cluster analysis of circulating biomarkers reported by Dr. Kwatra and colleagues in 2022, in the Journal of Investigative Dermatology.

In that study, the biomarker profile distinguished two distinct groups. Whites were more common in a cluster with relatively low expression of inflammatory markers (cluster 1), while Blacks were more common in a cluster with an inflammatory plasma profile (cluster 2), with higher relative expression of multiple cytokines, C-reactive protein, eosinophils, and other markers of up-regulated inflammation.

In addition to a lower rate of myelopathy in cluster 2 than cluster 1 (18% vs. 67%; P = .028), patients in cluster 2 had a significantly worse itch than those in cluster 1 on the Numeric Rating Scale for itch and a significantly lower quality of life based on the Dermatology Life Quality Index score.

Other work at Dr. Kwatra’s center that is based on genetic sequencing has provided evidence that Blacks – and Asians to a lesser extent – are predisposed genetically to develop nodules, perhaps explaining why the nodules tend to be larger than those seen in Whites.

The significance of the evidence that prurigo nodularis is associated with a more up-regulated inflammatory profile in Blacks than in Whites is that they might be particularly likely to respond to dupilumab or other targeted immunomodulating therapies that are in development, according to Dr. Kwatra. Although he did not provide data on response by race, he did provide several case examples of complete itch control following dupilumab therapy in Black patients.

In his experience, high levels of blood eosinophils and other inflammatory markers are predictors of response to dupilumab regardless of skin type, but he expressed concern that time to diagnosis is sometimes longer in Black patients if the nuances of disease expression are not appreciated.

For treating prurigo nodularis in Blacks as well as Whites, Dr. Kwatra suggested that clinicians stay current with what he predicted will be a growing array of treatment options. He did not discuss nemolizumab, an interleukin-31 receptor alpha antagonist. Soon after the meeting, results of a phase 3 trial of nemolizumab in patients with moderate to severe prurigo nodularis were published in the New England Journal of Medicine. (Dr. Kwatra is the lead author of the study but did not specifically discuss this treatment at the meeting.)

In the international placebo-controlled trial, called OLYMPIA 2, treatment was associated with a significant reduction in the signs and symptoms of prurigo nodularis, including reductions in itch, at 16 weeks, although only 4% of patients in the study were Black.

Given the expanding array of therapies, the message of considering prurigo nodularis in Black patients in order to accelerate the time to diagnosis is timely, Andrew F. Alexis, MD, MPH, professor of clinical dermatology and vice-chair for diversity and inclusion for the department of dermatology, Weill Cornell Medicine, New York.

“Current studies suggest a higher prevalence and greater severity of prurigo nodularis among Black patients compared to White patients,” said Dr. Alexis, agreeing with Dr. Kwatra. Referring to evidence that Blacks might mount a greater inflammatory response to prurigo nodularis than Whites, Dr. Alexis called for “a better understanding of the pathomechanisms” of this disease in order “to address unmet needs and reduce disparities for our diverse population of patients who suffer from prurigo nodularis.’

Dr. Kwatra reported financial relationships with AbbVie, Amgen, Arcutis, ASLAN, Cara, Castle Biosciences, Celldex, Galderma, Incyte, Johnson & Johnson, LEO pharma, Novartis, Pfizer, Regeneron, and Sanofi.

NEW YORK – As a result of recent progress in the control of prurigo nodularis, failure to recognize the differences in presentation across skin types threatens prolonged but preventable morbidity from a disease with a devastating clinical impact, according to an expert evaluating current approaches at the Skin of Color Update 2023.

“As dermatologists, prurigo nodularis is one of the most severe diseases we treat, said Shawn G. Kwatra, MD, director of the Johns Hopkins Itch Center, Baltimore. Now with one approved therapy and more coming, “it offers one of the most important opportunities we have to dramatically improve someone’s entire life.”

Prior to the September 2022 approval of dupilumab for the treatment of prurigo nodularis (the first treatment approved for this indication), Dr. Kwatra said that the limited options for control of pruritus made him anxious. Prurigo nodularis is characterized by highly itchy nodules that can produce symptoms patients describe as unbearable.

Good news for people struggling with sensory problems after a bout of COVID-19. Although mild cases of the disease often impair the ability to taste and smell, and the problem can drag on for months, a new study from Italy shows that most people return to their senses, as it were, within 3 years.

“In the vast majority of cases, the loss of the sense of smell is not irreversible,” said Paolo Boscolo-Rizzo, MD, a professor of medicine, surgery, and health sciences at the University of Trieste (Italy), and a co-author of the study, published as a research letter in JAMA Otolaryngology–Head & Neck Surgery.

Dr. Boscolo-Rizzo and his colleagues analyzed data from 88 adults with mild COVID-19, which was defined as having no lower respiratory disease and blood oxygen saturation of 94% or greater. Another group of 88 adults who never contracted the virus but sometimes had difficulties with smell and taste were also studied. In both groups, the average age was 49 years, all participants were White, and 58% were women.

The researchers tested participants’ sense of smell with sticks that contained different odors and checked their sense of taste with strips that had different tastes. Over time, fewer people had difficulty distinguishing odors. Three years after developing COVID-19, only 12 people had impaired smell, compared with 36 people at year 1 and 24 people at year 2. And at the 3-year mark, all participants had at least a partial ability to smell. 

The story was similar with sense of taste, with 10 of 88 people reporting impairments 3 years later. By then, people with COVID-19 were no more likely to have trouble with smell or taste than people who did not get the virus. 

A study this past June showed a strong correlation between severity of COVID-19 symptoms and impaired sense of taste and smell and estimated that millions of Americans maintained altered senses. More than 10% of people in the Italian study still had trouble with smell or taste 3 years later.
 

Emerging treatments, psychological concerns

“We’re seeing fewer people with this problem, but there are still people suffering from it,” said Fernando Carnavali, MD, an internal medicine physician and a site director for the Center for Post-COVID Care at the Icahn School of Medicine at Mount Sinai, New York City.

Dr. Carnavali wasn’t part of this study, but he did find the new results encouraging, and he called for similar studies in diverse populations that have experienced COVID-19. He also noted that an impaired sense of smell is distressing.

“It really has a significant psychological impact,” Dr. Carnavali said.

He recalled a patient crying in his office because her inability to smell made it impossible for her to cook. Dr. Carnavali recommended clinicians refer patients facing protracted loss of smell or taste to mental health professionals for support.

Treatments are emerging for COVID-19 smell loss. One approach is to inject platelet-rich plasma into a patient’s nasal cavities to help neurons related to smell repair themselves.

A randomized trial showed platelet-rich plasma significantly outperformed placebo in patients with smell loss up to a year after getting COVID-19.

“I wish more people would do it,” said Zara Patel, MD, an otolaryngologist at Stanford (Calif.) Medicine, who helped conduct that trial. She said some physicians may be nervous about injecting plasma so close to the skull and are therefore hesitant to try this approach. 

Another technique may help to address the olfactory condition known as parosmia, in which patients generally experience a benign odor as rancid, according to otolaryngologist Nyssa Farrell, MD, of Washington University School of Medicine, St. Louis. Dr. Farrell said around two-thirds of patients who contract COVID-19 develop the condition, and the rates of long-term parosmia range from 10%-50% depending on various studies.

“It is almost always foul; this can profoundly affect someone’s quality of life,” impairing their ability to eat or to be intimate with a partner who now smells unpleasant, said Dr. Farrell, who wasn’t associated with this research.

The treatment, called a stellate ganglion block, is provided through a shot into nerves in the neck. People with parosmia associated with COVID-19 often report that this method cures them. Dr. Patel said that may be because their psychological health is improving, not their sense of smell, because the area of the body where the stellate ganglion block is applied is not part of the olfactory system.

Earlier this year, Dr. Farrell and colleagues reported that parosmia linked to COVID-19 is associated with an increased risk for depression, anxiety, and suicidal ideation.
