Preventive Care

Two decades after the landmark Women’s Health Initiative (WHI) changed the way clinicians thought about hormone therapy and cancer, new findings suggest this national health study is "the gift that keeps on giving."

Follow-up from two of the WHI’s randomized trials have found that estrogen alone in women with prior hysterectomy significantly increased ovarian cancer incidence and mortality in postmenopausal women. Estrogen and progesterone together, meanwhile, did not increase ovarian cancer risk, and significantly reduced the risk of endometrial cancer. Rowan T. Chlebowski, MD, PhD, of The Lundquist Institute in Torrance, California, presented these results from the latest WHI findings, at the annual meeting of the American Society of Clinical Oncology in Chicago.

Dr. Chlebowski and his colleagues conducted an analysis from two randomized, placebo-controlled trials, which between 1993 and 1998 enrolled nearly 28,000 postmenopausal women aged 50-79 years without prior cancer from 40 centers across the United States. (The full WHI effort involved a total cohort of 161,000 patients, and included an observational study and two other non-drug trials.)

In one of the hormone therapy trials, 17,000 women with a uterus at baseline were randomized to combined equine estrogen plus medroxyprogesterone acetate, or placebo. In the other trial, about 11,000 women with prior hysterectomy were randomized to daily estrogen alone or placebo. Both trials were stopped early: the estrogen-only trial due to an increased stroke risk, and the combined therapy trial due to findings of increased breast cancer and cardiovascular risk.

Mean exposure to hormone therapy was 5.6 years for the combined therapy trial and 7.2 years for estrogen alone trial.
 

Ovarian Cancer Incidence Doubles with Estrogen

At 20 years’ follow up, with mortality information available for nearly the full cohort, Dr. Chlebowski and his colleagues could determine that ovarian cancer incidence doubled among women who had taken estrogen alone (hazard ratio = 2.04; 95% CI 1.14-3.65; P = .01), a difference that reached statistical significance at 12 years’ follow up. Ovarian cancer mortality was also significantly increased (HR = 2.79 95% CI 1.30-5.99, P = .006). Absolute numbers were small, however, with 35 cases of ovarian cancer compared with 17 in the placebo group.

Combined therapy recipients saw no increased risk for ovarian cancer and significantly lower endometrial cancer incidence (106 cases vs. 140 HR = 0.72; 95% CI, 0.56-0.92; P = .01).

Conjugated equine estrogen, Dr. Chlebowski said during his presentation at the meeting, “was introduced in US clinical practice in 1943 and used for over half a century, yet the question about hormone therapy’s influence on endometrial and ovarian cancer remains unsettled. Endometrial cancer and ovarian cancer are the fourth and fifth leading causes of cancer deaths in women ... and there’s some discordant findings from observational studies.”

Care of Ovarian Cancer Survivors Should Change

The new findings should prompt practice and guideline changes regarding the use of estrogen alone in ovarian cancer survivors, Dr. Chlebowski said.

In an interview, oncologist Eleonora Teplinsky, MD, of Valley-Mount Sinai Comprehensive Cancer Care in Paramus, New Jersey, said that apart from this subgroup of ovarian cancer survivors, the findings would not likely have much impact on how clinicians and patients approach hormone replacement therapy today.

“Twenty years ago the Women’s Health Initiative showed that hormone replacement therapy increases breast cancer risk, and everyone stopped taking HRT. And now people pushing back on it and saying wait a second – it was the estrogen plus progesterone that increased breast cancer, not estrogen alone. And now we’ve got these newer [estrogen] formulations.

“Yes, there’s a little bit of an increased risk [for ovarian cancer]. Patients should be aware. They should know the symptoms of ovarian cancer. But if they have indications and have been recommended HRT, this is not something that we would advise them against because of this very slightly increased risk,” Dr. Teplinsky said.

Oncologist Allison Kurian, MD of Stanford University in Stanford, California, who specializes in breast cancer, also noted that the duration of hormone treatment, treatment timing relative to age of menopause onset, and commonly used estrogen preparations had indeed changed since the time the WHI trials were conducted, making it harder to generalize the findings to current practice. Nonetheless, she argued, they still have real significance.

“WHI is an incredibly complex but also incredibly valuable resource,” said Dr. Kurian, who has conducted studies using WHI data. “The first big results came out in 2002, and we’re still learning from it. These are randomized trials, which offer the strongest form of scientific evidence that exists. So whenever we see results from this study, we have to take note of them,” she said.

Because the WHI trials had shown combined therapy, not estrogen alone, to be associated with breast cancer risk, clinicians have felt reassured over the years about using estrogen alone.

“You can’t give it to a person unless they have their uterus removed, because we know it will cause uterine cancer if the uterus is in place. But if the uterus is removed, the feeling was that you can give estrogen alone. I think the new piece that is going to get everyone’s attention is this signal for ovarian cancer.”

Something else the new findings show, Dr. Kurian said, is that WHI is “the gift that keeps on giving,” even after decades. “Some of the participants had a relatively short-term exposure to HRT. They took a medication for just a little while. But you didn’t see the effects until you followed people 12 years. So we’re now going to be a little more worried about ovarian cancer in this setting than we used to be. And that’s going to be something we’re all going to keep an eye on and think twice about in terms of talking to patients.”

These results help demonstrate what happens when a society invests in science on a national scale, Dr. Kurian said. “Here we have a really long-term, incredibly informative study that keeps generating knowledge to help women.”

When the WHI began, it “really was the first time that people decided it was important to systematically study women at midlife. It was a remarkable thing then that society got mobilized to do this, and we’re still seeing the benefits.”

Dr. Chlebowski disclosed receiving consulting or advisory fees from Pfizer. Dr. Teplinsky and Dr. Kurian disclosed no financial conflicts of interest.

Vaccination against human papillomavirus (HPV) is an effective way to prevent HPV infection and cancers typically caused by HPV, including cervical cancer and head and neck cancers, new research showed.

The analysis, featured at a press briefing ahead of the presentation at the American Society of Clinical Oncology (ASCO) 2024 annual meeting, notably found that men who received the HPV vaccine had a 56% lower risk for head and neck cancers.

“We’ve known for a long time that having the HPV vaccine can prevent the development of HPV infection, yes, but importantly, cancer,” primarily cervical cancer, said briefing moderator and ASCO president Lynn Schuchter, MD, Abramson Cancer Center, University of Pennsylvania, Philadelphia. “This is a really important study that extends the information about the impact.”

Using the US TriNetX database, lead investigator Jefferson DeKloe, BS, a research fellow with Thomas Jefferson University, Philadelphia, and colleagues created a matched cohort of 760,540 HPV-vaccinated and unvaccinated men and 945,999 HPV-vaccinated and unvaccinated women.

HPV-vaccinated men had a 54% lower risk for all HPV-related cancers (odds ratio [OR], 0.46; P < .001) and a 56% lower risk for head and neck cancers (OR, 0.44; P < .001) than unvaccinated men. There were not enough cases of anal and penile cancers for analysis.

HPV-vaccinated women had a 27% lower risk for all HPV-related cancers (OR, 0.73; P < .05), a 54% lower risk for cervical cancer (OR, 0.46; P < .05), and a 33% lower risk for head and neck cancers (OR, 0.67; 95% CI, 0.42-1.08) than HPV-unvaccinated women, but this finding was not significant. There were not enough cases of anal cancers for analysis, and the odds of developing vulvar or vaginal cancer was not significantly different in HPV-vaccinated vs unvaccinated women.

Vaccinated women, however, were less likely than unvaccinated women to develop high-grade squamous intraepithelial lesions (OR, 0.44), cervical carcinoma in situ (OR, 0.42), or abnormal Pap findings (OR, 0.87), and were less likely to undergo cone biopsy and loop electrosurgical excision (OR, 0.45).

“This study really highlights the importance of getting the HPV vaccine,” Dr. Schuchter said at the briefing.

“HPV vaccination is cancer prevention,” Glenn Hanna, MD, with Dana-Farber Cancer Institute, Boston, said in an ASCO statement.

Still, HPV vaccination rates in the United States remain relatively low. According to the National Cancer Institute, in 2022, only about 58% of adolescents aged 13-15 years had received two or three doses of HPV vaccine as recommended.

“The goal,” Dr. Schuchter said at the briefing, “is that younger girls and young boys get vaccinated to prevent development of HPV infection, and that should decrease the risk of cancer, which is what we’ve seen.”

Mr. DeKloe agreed and highlighted the importance of improving vaccination rates. “Identifying effective interventions that increase HPV vaccination rates is critical in reducing undue cancer burden in the United States,” Mr. DeKloe said in a statement.

The study had no funding source. Mr. DeKloe had no relevant disclosures. Dr. Hanna has disclosed relationships with Bicara Therapeutics, Bristol Myers Squibb, Coherus BioSciences, and others. Dr. Schuchter had no relevant disclosures.

The results of a large French study comparing the cancer risk in children conceived through assisted reproductive technology (ART) with that of naturally conceived children were published recently in JAMA Network Open. This study is one of the largest to date on this subject: It included 8,526,306 children born in France between 2010 and 2021, of whom 260,236 (3%) were conceived through ART, and followed them up to a median age of 6.7 years.

Motivations for the Study

ART (including artificial insemination, in vitro fertilization [IVF], or intracytoplasmic sperm injection [ICSI] with fresh or frozen embryo transfer) accounts for about 1 in 30 births in France. However, limited and heterogeneous data have suggested an increased risk for certain health disorders, including cancer, among children conceived through ART. Therefore, a large-scale evaluation of cancer risk in these children is important.

No Overall Increase

In all, 9256 children developed cancer, including 292 who were conceived through ART. Thus, this study did not show an increased risk for cancer (of all types combined) in children conceived through ART. Nevertheless, a slight increase in the risk for leukemia was observed in children conceived through IVF or ICSI. The investigators observed approximately one additional case for every 5000 newborns conceived through IVF or ICSI who reached age 10 years.

Epidemiological monitoring should be continued to better evaluate long-term risks and see whether the risk for leukemia is confirmed. If it is, then it will be useful to investigate the mechanisms related to ART techniques or the fertility disorders of parents that could lead to an increased risk for leukemia.

In all, 9256 children developed cancer, including 292 who were conceived through ART. Thus, this study did not show an increased risk for cancer (of all types combined) in children conceived through ART. Nevertheless, a slight increase in the risk for leukemia was observed in children conceived through IVF or ICSI. The investigators observed approximately one additional case for every 5000 newborns conceived through IVF or ICSI who reached age 10 years.

Epidemiological monitoring should be continued to better evaluate long-term risks and see whether the risk for leukemia is confirmed. If it is, then it will be useful to investigate the mechanisms related to ART techniques or the fertility disorders of parents that could lead to an increased risk for leukemia.

Celiac disease is a chronic, immune-mediated, systemic disorder caused by intolerance to gluten — a protein present in rye, barley, and wheat grains — that affects genetically predisposed individuals.

Due to its wide spectrum of clinical manifestations, celiac disease resembles a multisystemic disorder. Its most common gastrointestinal (GI) symptoms include chronic diarrhea, weight loss, and abdominal distention. However, celiac disease can also manifest in myriad extraintestinal symptoms, ranging from headache and fatigue to delayed puberty and psychiatric disorders, with differing presentations in children and adults.

To date, the only treatment is adopting a gluten-free diet (GFD). Although key to preventing persistent villous atrophy, the main cause of complications in celiac disease, lifelong adherence to GFD is challenging and may not resolve all clinical issues. These shortcomings have driven recent efforts to develop novel therapeutic options for patients with this disease.

Here are five things to know about celiac disease.
 

1. Rising Prevalence of Celiac Disease and Other Autoimmune Disorders Suggests Environmental Factors May Be at Play

Gluten was first identified as the cause of celiac disease in the 1950s. At that time, the condition was thought to be a relatively rare GI disease of childhood that primarily affected people of European descent, but it is now known to be a common disease affecting those of various ages, races, and ethnicities.

A 2018 meta-analysis found the pooled global prevalence of celiac disease was 1.4%. Incidence has increased by as much as 7.5% annually over the past several decades.

Increased awareness among clinicians and improved detection likely play a role in the trend. However, the growth in celiac disease is consistent with that seen for other autoimmune disorders, according to a 2024 update of evidence surrounding celiac disease. Shared environmental factors have been proposed as triggers for celiac disease and other autoimmune diseases and appear to be influencing their rise, the authors noted. These factors include migration and population growth, changing dietary patterns and food processing practices, and altered wheat consumption.
 

2. No-Biopsy Diagnosis Is Accepted for Children and Shows Promise for Adults

It is estimated that almost 60 million people worldwide have celiac disease, but most remain undiagnosed or misdiagnosed, or they experience significant diagnostic delays.

Prospective data indicate that children with first-degree relatives with celiac disease are at a significantly higher risk of developing the condition, which should prompt screening efforts in this population.

The 2023 updated guidelines from the American College of Gastroenterology (ACG) state that serology testing plays a central role in screening. This commonly involves serological testing for positive serological markers of the disease, including immunoglobulin A (IgA), anti-tissue transglutaminase IgA (tTG-IgA), anti-deamidated gliadin peptide, or endomysial antibodies.

To confirm diagnosis, clinicians have relied on intestinal biopsy since the late 1950s. The ACG still recommends esophagogastroduodenoscopy with multiple duodenal biopsies for confirmation of diagnosis in both children and adults with suspicion of celiac disease. However, recent years have seen a shift toward a no-biopsy approach.

For more than a decade in Europe, a no-biopsy approach has been established practice in pediatric patients, for whom the burden of obtaining a histological confirmation is understandably greater. Most guidelines now permit children to be diagnosed with celiac disease in the absence of a biopsy under specific circumstances (eg, characteristic symptoms of celiac disease and tTG-IgA levels > 10 times the upper limit of normal). The ACG guidelines state that “this approach is a reasonable alternative to the standard approach to a [celiac disease] diagnosis in selected children.”

The ACG does not recommend a no-biopsy approach in adults, noting that, in comparison with children, there is a relative lack of data indicating that serology is predictive in this population. However, it does recognize that physicians may encounter patients for whom a biopsy diagnosis may not be safe or practical. In such cases, an “after-the-fact” diagnosis of likely celiac disease can be given to symptomatic adult patients with a ≥ 10-fold elevation of tTG-IgA and a positive endomysial antibody in a second blood sample.

A 2024 meta-analysis of 18 studies involving over 12,103 adult patients from 15 countries concluded that a no-biopsy approach using tTG-IgA antibody levels ≥ 10 times the upper limit of normal was highly specific and predictive of celiac disease.
 

3. Celiac Disease Is Associated With Several Life-Threatening Conditions

Emerging data indicate that gastroenterologists should be vigilant in screening patients with celiac disease for several other GI conditions.

Inflammatory bowel disease and celiac disease have a strong bidirectional association, suggesting a possible genetic link between the conditions and indicating that physicians should consider the alternate diagnosis when symptoms persist after treatment.

Given the hypervigilance around food and diet inherent to celiac disease, patients are at an increased risk of developing avoidant/restrictive food intake disorder, according to a 2022 retrospective study.

In 2023, Italian investigators showed that children with celiac disease have an elevated prevalence of functional GI disorders even after adopting a GFD for a year, regardless of whether they consumed processed or natural foods. It was unclear whether this was due to a chronic inflammatory process or to nutritional factors.

Complications resulting from celiac disease are not limited to GI disorders. For a variety of underlying pathophysiological reasons, including intestinal permeability, hyposplenism, and malabsorption of nutrients, patients with celiac disease may be at a higher risk for non-GI conditions, such as osteopenia, women’s health disorders (eg, ovarian failure, endometriosis, or pregnancy loss), juvenile idiopathic arthritis in children and rheumatoid arthritis in adults, certain forms of cancer, infectious diseases, and cardiomyopathy.
 

4. GFD Is the Only Treatment, but It’s Imperfect and Frustrating for Patients

GFD is the only treatment for celiac disease and must be adhered to without deviation throughout a patient’s life.

Maintaining unwavering adherence reaps considerable benefits: Improved clinical symptoms, robust mucosal healing, and normalization of serological markers. Yet it also takes a considerable toll on patients. Patients with celiac disease struggle with a host of negative physical, psychological, and social impacts. They also report a higher treatment burden than those with gastroesophageal reflux disease or hypertension, and comparable with end-stage renal disease.

GFD also poses financial challenges. Although the price of gluten-free products has decreased in recent years, they still cost significantly more than items with gluten.

Adherence to GFD does not always equate to complete mucosal recovery. While mucosal recovery is achieved in 95% of children within 2 years of the diet’s adoption, only 34% and 66% of adults obtain it within 2 and 5 years, respectively.

GFD may lead to nutrient imbalances because gluten-free foods are typically low in alimentary fiber, micronutrients (eg, vitamin D, vitamin B12, or folate), and minerals (eg, iron, zinc, magnesium, or calcium). With higher sugar and fat content, GFD may leave patients susceptible to unwanted weight gain.

The pervasiveness of gluten in the food production system makes the risk for cross-contamination high. Gluten is often found in both naturally gluten-free foods and products labeled as such. Gluten-sensing technologies, some of which can be used via smartphone apps, have been developed to help patients identify possible cross-contamination. However, the ACG guidelines recommend against the use of these technologies until there is sufficient evidence supporting their ability to improve adherence and clinical outcomes.
 

5. Novel Therapies for Celiac Disease Are in the Pipeline

The limitations of GFD as the standard treatment for celiac disease have led to an increased focus on developing novel therapeutic interventions. They can be sorted into five key categories: Modulation of the immunostimulatory effects of toxic gluten peptides, elimination of toxic gluten peptides before they reach the intestine, induction of gluten tolerance, modulation of intestinal permeability, and restoration of gut microbiota balance.

Three therapies designed to block antigen presentation by HLA-DQ2/8, the gene alleles that predispose people to celiac disease, show promise: TPM502, an agent that contains three gluten-specific antigenic peptides with overlapping T-cell epitopes for the HLA-DQ2.5 gene; KAN-101, designed to induce gluten tolerance by targeting receptors on the liver; and DONQ52, a multi-specific antibody that targets HLA-DQ2. The KAN-101 therapy received Fast Track designation by the US Food and Drug Administration in 2022.

These and several other agents in clinical and preclinical development are discussed in detail in a 2024 review article. Although no therapies have reached phase 3 testing, when they do, it will undoubtedly be welcomed by those with celiac disease.

In a study of adults, an increase of 1 g in estimated 24-hour urinary sodium excretion was associated with 11% higher odds of an atopic dermatitis (AD) diagnosis, 16% higher odds of having active AD, and 11% higher odds of increased severity of AD.

Those are key findings from a cross-sectional analysis of data from the United Kingdom.

“Excessive dietary sodium, common in fast food, may be associated with AD,” corresponding author Katrina Abuabara, MD, MA, MSCE, and colleagues wrote in the study, which was published online in JAMA Dermatology. They referred to recent research using sodium MRI, which showed that “the majority of the body’s exchangeable sodium is stored in the skin and that skin sodium is associated with autoimmune and chronic inflammatory conditions, including AD.” And in another study published in 2019, lesional skin sodium was 30-fold greater in patients with AD than in healthy controls.

To investigate whether there is an association between higher levels of sodium consumption and AD prevalence, activity, and severity at the population level, Dr. Abuabara, of the program for clinical research in the Department of Dermatology at the University of California, San Francisco, and coauthors drew from the UK Biobank, a population-based cohort of more than 500,000 individuals aged 37-73 years at the time of recruitment by the National Health Service. The primary exposure was 24-hour urinary sodium excretion, which was calculated by using the INTERSALT equation, a sex-specific estimation that incorporates body mass index; age; and urine concentrations of potassium, sodium, and creatinine. The primary study outcome was AD or active AD based on diagnostic and prescription codes from linked electronic medical records. The researchers used multivariable logistic regression models adjusted for age, sex, race and ethnicity, Townsend deprivation index, and education to measure the association.

Of the 215,832 Biobank participants included in the analysis, 54% were female, their mean age was 57 years, 95% were White, their mean estimated 24-hour urine sodium excretion was 3.01 g/day, and 10,839 (5%) had a diagnosis of AD. The researchers observed that on multivariable logistic regression, a 1-g increase in estimated 24-hour urine sodium excretion was associated with increased odds of AD (adjusted odds ratio [AOR], 1.11; 95% CI, 1.07-1.14), increased odds of active AD (AOR, 1.16; 95% CI, 1.05-1.28), and increased odds of increasing severity of AD (AOR, 1.11; 95% CI, 1.07-1.15).
 

Validating Results With US Data

To validate the findings, the researchers evaluated a cohort of 13,014 participants from the US-based National Health and Nutrition Examination Survey (NHANES), using pooled data from the 1999-2000, 2001-2002, and 2003-2004 samples. Of the 13,014 participants, 796 reported current AD, and 1493 reported AD in the past year. The mean dietary sodium intake of overall NHANES participants estimated with 24-hour dietary recall questionnaires was 3.45 g, with a mean of 3.47 g for those with current AD and a mean of 3.44 g for those without AD.

The researchers observed that a 1-g/day higher dietary sodium intake was associated with a higher risk for current AD (AOR, 1.22; 95%CI, 1.01-1.47) and a somewhat higher risk for AD in the past year (AOR, 1.14; 95% CI, 0.97-1.35).

“Future work should examine whether variation of sodium intake over time might trigger AD flares and whether it helps to explain heterogeneity in response to new immunomodulatory treatments for AD,” the authors wrote. “Reduced sodium intake was recommended as a treatment for AD more than a century ago, but there have yet to be studies examining the association of dietary sodium reduction with skin sodium concentration or AD severity,” they added. Noting that sodium reduction “has been shown to be a cost-effective intervention for hypertension and other cardiovascular disease outcomes,” they said that their data “support experimental studies of this approach in AD.”

They acknowledged certain limitations of the study, including the fact that a single spot urine sample was used in the UK Biobank cohort, “which only captures dietary intake of the last 24 hours and is not the best measure of usual or long-term intake of sodium.” They also noted that the findings may not be generalizable to other populations and that AD was based on self-report in the NHANES validation cohort.

Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, who was asked to comment on the results, said the study by Dr. Abuabara and colleagues “gives us another reason to avoid salt, showing that 1 g/day of higher salt intake increases the risk of AD in an adult population and more severe AD.”

He added that, “Now, can you say that reducing salt intake will have a therapeutic effect or clinically relevant impact? No. [That is] certainly worth exploring but at a minimum, gives some more credibility to keeping it bland.”

The study was supported by a grant from the Medical Student in Aging Research Program, the National Institute on Aging, and the National Eczema Association. Dr. Abuabara reported receiving research funding for her institution from Pfizer and Cosmetique Internacional/La Roche-Posay and consulting fees from Target RWE, Sanofi, Nektar, and Amgen. No other disclosures were reported. Dr. Friedman had no relevant disclosures.

The primary exposure was 24-hour urinary sodium excretion, which was calculated by using the INTERSALT equation, a sex-specific estimation that incorporates body mass index; age; and urine concentrations of potassium, sodium, and creatinine. The primary study outcome was AD or active AD based on diagnostic and prescription codes from linked electronic medical records. The researchers used multivariable logistic regression models adjusted for age, sex, race and ethnicity, Townsend deprivation index, and education to measure the association.

Of the 215,832 Biobank participants included in the analysis, 54% were female, their mean age was 57 years, 95% were White, their mean estimated 24-hour urine sodium excretion was 3.01 g/day, and 10,839 (5%) had a diagnosis of AD. The researchers observed that on multivariable logistic regression, a 1-g increase in estimated 24-hour urine sodium excretion was associated with increased odds of AD (adjusted odds ratio [AOR], 1.11; 95% CI, 1.07-1.14), increased odds of active AD (AOR, 1.16; 95% CI, 1.05-1.28), and increased odds of increasing severity of AD (AOR, 1.11; 95% CI, 1.07-1.15).
 

Validating Results With US Data

To validate the findings, the researchers evaluated a cohort of 13,014 participants from the US-based National Health and Nutrition Examination Survey (NHANES), using pooled data from the 1999-2000, 2001-2002, and 2003-2004 samples. Of the 13,014 participants, 796 reported current AD, and 1493 reported AD in the past year. The mean dietary sodium intake of overall NHANES participants estimated with 24-hour dietary recall questionnaires was 3.45 g, with a mean of 3.47 g for those with current AD and a mean of 3.44 g for those without AD.

The researchers observed that a 1-g/day higher dietary sodium intake was associated with a higher risk for current AD (AOR, 1.22; 95%CI, 1.01-1.47) and a somewhat higher risk for AD in the past year (AOR, 1.14; 95% CI, 0.97-1.35).

“Future work should examine whether variation of sodium intake over time might trigger AD flares and whether it helps to explain heterogeneity in response to new immunomodulatory treatments for AD,” the authors wrote. “Reduced sodium intake was recommended as a treatment for AD more than a century ago, but there have yet to be studies examining the association of dietary sodium reduction with skin sodium concentration or AD severity,” they added. Noting that sodium reduction “has been shown to be a cost-effective intervention for hypertension and other cardiovascular disease outcomes,” they said that their data “support experimental studies of this approach in AD.”

They acknowledged certain limitations of the study, including the fact that a single spot urine sample was used in the UK Biobank cohort, “which only captures dietary intake of the last 24 hours and is not the best measure of usual or long-term intake of sodium.” They also noted that the findings may not be generalizable to other populations and that AD was based on self-report in the NHANES validation cohort.

Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, who was asked to comment on the results, said the study by Dr. Abuabara and colleagues “gives us another reason to avoid salt, showing that 1 g/day of higher salt intake increases the risk of AD in an adult population and more severe AD.”

He added that, “Now, can you say that reducing salt intake will have a therapeutic effect or clinically relevant impact? No. [That is] certainly worth exploring but at a minimum, gives some more credibility to keeping it bland.”

The study was supported by a grant from the Medical Student in Aging Research Program, the National Institute on Aging, and the National Eczema Association. Dr. Abuabara reported receiving research funding for her institution from Pfizer and Cosmetique Internacional/La Roche-Posay and consulting fees from Target RWE, Sanofi, Nektar, and Amgen.

In a study of adults, an increase of 1 g in estimated 24-hour urinary sodium excretion was associated with 11% higher odds of an atopic dermatitis (AD) diagnosis, 16% higher odds of having active AD, and 11% higher odds of increased severity of AD.

Those are key findings from a cross-sectional analysis of data from the United Kingdom.

“Excessive dietary sodium, common in fast food, may be associated with AD,” corresponding author Katrina Abuabara, MD, MA, MSCE, and colleagues wrote in the study, which was published online in JAMA Dermatology. They referred to recent research using sodium MRI, which showed that “the majority of the body’s exchangeable sodium is stored in the skin and that skin sodium is associated with autoimmune and chronic inflammatory conditions, including AD.” And in another study published in 2019, lesional skin sodium was 30-fold greater in patients with AD than in healthy controls.

I’d like to talk with you about a recent report in the British Medical Journal on the regular use of omega-3 fish oil supplements and the course of cardiovascular disease (CVD).

This is an observational study from the large-scale UK Biobank. The authors divided the participants into those with and those without CVD. In participants without CVD at baseline, those using fish oil supplements regularly had an increased incidence of both atrial fibrillation (AF) and stroke, whereas those with prevalent CVD had a reduction in the progression to major adverse cardiovascular events, which offset any increase in the risk for AF.

Observational studies of omega-3 supplements have potential limitations and confounding, and correlation in these studies does not prove causation. What do the randomized clinical trials of omega-3 supplements show? At least seven randomized trials have looked at AF. A meta-analysis published in Circulation in 2021 showed a dose-response relationship. In trials testing > 1 g/d of marine omega-3 fatty acids, there was close to a 50% overall increase in risk for AF. In studies testing lower doses, there was a very modest 12% increase and a significant dose-response gradient.

For the relationship between omega-3 supplements and major cardiovascular events, at least 15 individual randomized trials have been conducted. There actually have been more meta-analyses of these randomized trials than individual trials. The meta-analyses tend to show a significant reduction of coronary events with omega-3 supplementation, but no reduction in stroke. This is true in both primary and secondary prevention trials.

The one exception to this finding is the REDUCE-IT trial testing high-dose eicosapentaenoic acid (EPA) (4 g/day of icosapent ethyl), and there was a 25%-30% reduction in both cardiovascular events and stroke. But there has been some criticism of the mineral oil placebo used in the REDUCE-IT trial that it may have had adverse effects on biomarkers and might have interfered with the absorption of statins in the placebo group. So, it will be important to have a replication trial of the high-dose EPA, findings in a trial using an inert placebo such as corn oil.

What should be done in the meantime? It’s important to think about prescription omega-3s vs over-the-counter fish oil. The US Food and Drug Administration (FDA) has approved prescription omega-3 medications for several indications, including severely elevated triglyceride levels (> 500 mg/dL). In the REDUCE-IT trial, those who had moderate elevations of triglycerides (≥ 150 mg/dL) or prevalent CVD or diabetes, plus two additional risk factors, were also considered to have indications based on the FDA labeling for icosapent ethyl.

What about patients who don’t meet these criteria for prescription omega-3s? In the VITAL trial (the large-scale primary prevention trial), there was a similar reduction in coronary events but no effect on stroke. Those who seemed to benefit the most in terms of at least 40% reduction in coronary events were participants who had low fish consumption at baseline, had two or more risk factors for cardiovascular disease, or were African American. 

Someone who rarely or never eats fish and has multiple risk factors for CVD, but doesn’t meet criteria for prescription omega-3 medication, may want to discuss with their clinician the use of over-the-counter fish oil supplements. But fish oil and other dietary supplements will never be a substitute for healthy diet and healthy lifestyle. There is a national recommendation for one to two servings of fish per week. For those planning to take fish oil, it’s important to use reputable sources of the supplement, and check the bottle for a quality control seal. It’s also really important to avoid megadoses of fish oil, because high doses have been linked to an increased risk for AF and bleeding.

There has been much hyperbole since the presentation of results from the SELECT cardiovascular outcomes trial (CVOT) at this year’s European Congress on Obesity, which led many to herald semaglutide as the “new statin.”

In the SELECT CVOT, participants with overweight or obesity (body mass index [BMI] ≥ 27), established cardiovascular disease (CVD), and no history of type 2 diabetes were administered the injectable glucagon-like peptide 1 (GLP-1) receptor agonist semaglutide (Wegovy) at a 2.4-mg dose weekly. Treatment resulted in a significant 20% relative risk reduction in major adverse CV events (a composite endpoint comprising CV death, nonfatal myocardial infarction, or nonfatal stroke). Importantly, SELECT was a trial on secondary prevention of CVD. 

The CV benefits of semaglutide were notably independent of baseline weight or amount of weight lost. This suggests that the underlying driver of improved CV outcomes with semaglutide extends beyond simple reduction in obesity and perhaps indicates a direct effect on vasculature and reduction in atherosclerosis, although this remains unproven.
 

Not All Risk Reduction Is Equal 

Much of the sensationalist coverage in the lay press focused on the 20% relative risk reduction figure. This endpoint is often more impressive and headline-grabbing than the absolute risk reduction, which provides a clearer view of a treatment’s real-world impact.

In SELECT, the absolute risk reduction was 1.5 percentage points, which translated into a number needed to treat (NNT) of 67 over 34 months to prevent one primary outcome of a major adverse CV event.

Lower NNTs suggest more effective treatments because fewer people need to be treated to prevent one clinical event, such as the major adverse CV events used in SELECT.
 

Semaglutide vs Statins

How does the clinical effectiveness observed in the SELECT trial compare with that observed in statin trials when it comes to the secondary prevention of CVD?

The seminal 4S study published in 1994 explored the impact of simvastatin on all-cause mortality among people with previous myocardial infarction or angina and hyperlipidemia (mean baseline BMI, 26). After 5.4 years of follow-up, the trial was stopped early owing to a 3.3-percentage point absolute risk reduction in all-cause mortality (NNT, 30; relative risk reduction, 28%). The NNT to prevent one death from CV causes was 31, and the NNT to prevent one major coronary event was lower, at 15.

Other statin secondary prevention trials, such as the LIPID and MIRACL studies, demonstrated similarly low NNTs.

So, you can see that the NNTs for statins in secondary prevention are much lower than with semaglutide in SELECT. Furthermore, the benefits of semaglutide in preventing CVD in people living with overweight/obesity have yet to be elucidated. 

In contrast, we already have published evidence showing the benefits of statins in the primary prevention of CVD, albeit with higher and more variable NNTs than in the statin secondary prevention studies. 

The benefits of statins are also postulated to extend beyond their impact on lowering low-density lipoprotein cholesterol. Statins have been suggested to have anti-inflammatory and plaque-stabilizing effects, among other pleiotropic benefits.

We also currently lack evidence for the cost-effectiveness of semaglutide for CV risk reduction. Assessing economic viability and use in health care systems, such as the UK’s National Health Service, involves comparing the cost of semaglutide against the health care savings from prevented CV events. Health economic studies are vital to determine whether the benefits justify the expense. In contrast, the cost-effectiveness of statins is well established, particularly for high-risk individuals.
 

Advantages of GLP-1s Should Not Be Overlooked

Of course, statins don’t provide the significant weight loss benefits of semaglutide. 

Additional data from SELECT presented at the 2024 European Congress on Obesity demonstrated that participants lost a mean of 10.2% body weight and 7.7 cm from their waist circumference after 4 years. Moreover, after 2 years, 12% of individuals randomized to semaglutide had returned to a normal BMI, and nearly half were no longer living with obesity.

Although the CV benefits of semaglutide were independent of weight reduction, this level of weight loss is clinically meaningful and will reduce the risk of many other cardiometabolic conditions including type 2 diabetes, metabolic dysfunction–associated steatotic liver disease, and obstructive sleep apnea/hypopnea syndrome, as well as improve low mood, depression, and overall quality of life. Additionally, obesity is now a risk factor for 13 different types of cancer, including bowel, breast, and pancreatic cancer, so facilitating a return to a healthier body weight will also mitigate future risk for cancer.
 

Sticking With Our Cornerstone Therapy, For Now

In conclusion, I do not believe that semaglutide is the “new statin.” Statins are the cornerstone of primary and secondary prevention of CVD in a wide range of comorbidities, as evidenced in multiple large and high-quality trials dating back over 30 years.

However, there is no doubt that the GLP-1 receptor agonist class is the most significant therapeutic advance for the management of obesity and comorbidities to date. 

The SELECT CVOT data uniquely position semaglutide as a secondary CVD prevention agent on top of guideline-driven management for people living with overweight/obesity and established CVD. Additionally, the clinically meaningful weight loss achieved with semaglutide will impact the risk of developing many other cardiometabolic conditions, as well as improve mental health and overall quality of life.

The SELECT CVOT data uniquely position semaglutide as a secondary CVD prevention agent on top of guideline-driven management for people living with overweight/obesity and established CVD. Additionally, the clinically meaningful weight loss achieved with semaglutide will impact the risk of developing many other cardiometabolic conditions, as well as improve mental health and overall quality of life.

There has been much hyperbole since the presentation of results from the SELECT cardiovascular outcomes trial (CVOT) at this year’s European Congress on Obesity, which led many to herald semaglutide as the “new statin.”

In the SELECT CVOT, participants with overweight or obesity (body mass index [BMI] ≥ 27), established cardiovascular disease (CVD), and no history of type 2 diabetes were administered the injectable glucagon-like peptide 1 (GLP-1) receptor agonist semaglutide (Wegovy) at a 2.4-mg dose weekly. Treatment resulted in a significant 20% relative risk reduction in major adverse CV events (a composite endpoint comprising CV death, nonfatal myocardial infarction, or nonfatal stroke). Importantly, SELECT was a trial on secondary prevention of CVD. 

The CV benefits of semaglutide were notably independent of baseline weight or amount of weight lost. This suggests that the underlying driver of improved CV outcomes with semaglutide extends beyond simple reduction in obesity and perhaps indicates a direct effect on vasculature and reduction in atherosclerosis, although this remains unproven.
 

Not All Risk Reduction Is Equal 

Much of the sensationalist coverage in the lay press focused on the 20% relative risk reduction figure. This endpoint is often more impressive and headline-grabbing than the absolute risk reduction, which provides a clearer view of a treatment’s real-world impact.

In SELECT, the absolute risk reduction was 1.5 percentage points, which translated into a number needed to treat (NNT) of 67 over 34 months to prevent one primary outcome of a major adverse CV event.

Lower NNTs suggest more effective treatments because fewer people need to be treated to prevent one clinical event, such as the major adverse CV events used in SELECT.
 

Semaglutide vs Statins

How does the clinical effectiveness observed in the SELECT trial compare with that observed in statin trials when it comes to the secondary prevention of CVD?

The seminal 4S study published in 1994 explored the impact of simvastatin on all-cause mortality among people with previous myocardial infarction or angina and hyperlipidemia (mean baseline BMI, 26). After 5.4 years of follow-up, the trial was stopped early owing to a 3.3-percentage point absolute risk reduction in all-cause mortality (NNT, 30; relative risk reduction, 28%). The NNT to prevent one death from CV causes was 31, and the NNT to prevent one major coronary event was lower, at 15.

Other statin secondary prevention trials, such as the LIPID and MIRACL studies, demonstrated similarly low NNTs.

So, you can see that the NNTs for statins in secondary prevention are much lower than with semaglutide in SELECT. Furthermore, the benefits of semaglutide in preventing CVD in people living with overweight/obesity have yet to be elucidated. 

In contrast, we already have published evidence showing the benefits of statins in the primary prevention of CVD, albeit with higher and more variable NNTs than in the statin secondary prevention studies. 

The benefits of statins are also postulated to extend beyond their impact on lowering low-density lipoprotein cholesterol. Statins have been suggested to have anti-inflammatory and plaque-stabilizing effects, among other pleiotropic benefits.

We also currently lack evidence for the cost-effectiveness of semaglutide for CV risk reduction. Assessing economic viability and use in health care systems, such as the UK’s National Health Service, involves comparing the cost of semaglutide against the health care savings from prevented CV events. Health economic studies are vital to determine whether the benefits justify the expense. In contrast, the cost-effectiveness of statins is well established, particularly for high-risk individuals.
 

Advantages of GLP-1s Should Not Be Overlooked

Of course, statins don’t provide the significant weight loss benefits of semaglutide. 

Additional data from SELECT presented at the 2024 European Congress on Obesity demonstrated that participants lost a mean of 10.2% body weight and 7.7 cm from their waist circumference after 4 years. Moreover, after 2 years, 12% of individuals randomized to semaglutide had returned to a normal BMI, and nearly half were no longer living with obesity.

Although the CV benefits of semaglutide were independent of weight reduction, this level of weight loss is clinically meaningful and will reduce the risk of many other cardiometabolic conditions including type 2 diabetes, metabolic dysfunction–associated steatotic liver disease, and obstructive sleep apnea/hypopnea syndrome, as well as improve low mood, depression, and overall quality of life. Additionally, obesity is now a risk factor for 13 different types of cancer, including bowel, breast, and pancreatic cancer, so facilitating a return to a healthier body weight will also mitigate future risk for cancer.
 

Sticking With Our Cornerstone Therapy, For Now

In conclusion, I do not believe that semaglutide is the “new statin.” Statins are the cornerstone of primary and secondary prevention of CVD in a wide range of comorbidities, as evidenced in multiple large and high-quality trials dating back over 30 years.

However, there is no doubt that the GLP-1 receptor agonist class is the most significant therapeutic advance for the management of obesity and comorbidities to date. 

The SELECT CVOT data uniquely position semaglutide as a secondary CVD prevention agent on top of guideline-driven management for people living with overweight/obesity and established CVD. Additionally, the clinically meaningful weight loss achieved with semaglutide will impact the risk of developing many other cardiometabolic conditions, as well as improve mental health and overall quality of life.

Over a period of 5 years, the likelihood of major adverse cardiovascular events (MACE) in patients with psoriasis and dyslipidemia who were on statin therapy was 40% greater than that in non-psoriasis patients with dyslipidemia on statin therapy, even after adjusting for covariates, results from a large retrospective study showed.

“It is well-established that psoriasis is an independent risk factor for the development of MACE, with cardiometabolic risk factors being more prevalent and incident among patients with psoriasis,” the study’s first author Ana Ormaza Vera, MD, a dermatology research fellow at Eastern Virginia Medical School, Norfolk, said in an interview after the annual meeting of the Society for Investigational Dermatology, where the study was presented during a late-breaking abstract session.

Current guidelines from the joint American Academy of Dermatology/National Psoriasis Foundation and the American Academy of Cardiology/American Heart Association Task Force recommend statins, a lipid-lowering and anti-inflammatory therapy, “for patients with psoriasis who have additional risk-enhancing factors, similar to recommendations made for the general population without psoriasis,” she noted. But how the incidence of MACE differs between patients with and without psoriasis while on statin therapy “has not been explored in real-world settings,” she added.

To address this question, the researchers used real-world data from the TriNetX health research network to identify individuals aged 18-90 years with a diagnosis of both psoriasis and lipid disorders who were undergoing treatment with statins. Those with a prior history of MACE were excluded from the analysis. Patients with lipid disorders on statin therapy, but without psoriatic disease, were matched 1:1 by age, sex, race, ethnicity, common risk factors for MACE, and medications shown to reduce MACE risk. The researchers then assessed the cohorts 5 years following their first statin prescription and used the TriNetX analytics tool to calculate the odds ratio (OR) with 95% CI to evaluate the likelihood of MACE in the presence of statin therapy.

Dr. Ormaza Vera and colleagues identified 20,660 patients with psoriasis and 2,768,429 patients without psoriasis who met the criteria for analysis. After propensity score matching, each cohort included 20,660 patients with a mean age of 60 years. During the 5-year observation period, 2725 patients in the psoriasis cohort experienced MACE compared with 2203 patients in the non-psoriasis cohort (OR, 1.40; 95% CI, 1.317-1.488).

[embed:render:related:node:267072]

“This was an unexpected outcome that challenges the current understanding and highlights the need for further research into tailored treatments for cardiovascular risk in psoriasis patients,” Dr. Ormaza Vera told this news organization.

She acknowledged certain limitations of the study, including its retrospective design, the inherent limitations of an observational study, and the use of electronic medical record data.

Lawrence J. Green, MD, clinical professor of dermatology, George Washington University, Washington, who was asked to comment on the study results, said that the findings imply that there is more than statin use alone to protect someone with psoriasis from having an increased risk for MACE. “This is not really surprising because statin use alone is only part of a prevention strategy in someone with psoriasis who usually has multiple comorbidities,” Dr. Green said. “On the other hand, the study only went out for 5 years and cardiovascular disease is a long accumulating process, so it could also be too early to demonstrate MACE prevention.”

The study was funded by a grant from the American Skin Association. Dr. Ormaza Vera and her coauthors reported having no relevant disclosures. Dr. Green disclosed that he is a speaker, consultant, or investigator for many pharmaceutical companies.

TOPLINE:

Arterial stiffness increases the risk for developing glaucoma, a new study found.

METHODOLOGY:

• To study the link between arterial stiffness and glaucoma, the researchers evaluated 4713 individuals (mean age, 66 years; 58% men) without the eye condition at baseline between April 2011 and November 2012.
• They assessed arterial stiffness by measuring aortic pulse wave velocity, estimated carotid-femoral pulse wave velocity, and aortic pulse pressure.
• The primary outcome was incident glaucoma, identified from prescriptions for eye drops or hospital records.

TAKEAWAY:

• Overall, 301 people in the study developed glaucoma over a mean follow-up period of 10.5 years.
• For every standard deviation increase in aortic pulse wave velocity, participants had a 32% higher risk for developing glaucoma (standardized hazard ratio [sHR], 1.32; 95% CI, 1.10-1.60), while estimated carotid-femoral pulse wave velocity was associated with a 37% higher risk (sHR, 1.37; 95% CI, 1.11-1.70).
• Incident glaucoma increased across all quartiles of arterial stiffness, with the highest risk observed in the fourth quartile for aortic pulse wave velocity (HR, 2.41; 95% CI, 1.36-4.26), estimated carotid-femoral pulse wave velocity (HR, 2.29; 95% CI, 1.27-4.13), and aortic pulse pressure (HR, 1.76; 95% CI, 1.10-2.82).
• The cumulative incidence of glaucoma rose with increases in arterial stiffness. This trend was statistically significant for both aortic and estimated pulse wave velocity (P < .0001) and aortic pulse pressure (P = .02).

IN PRACTICE:

“Arterial stiffness…which can be easily and accurately measured, could be used as a tool in clinical practice [as part of routine blood pressure measurement] to help identify people at risk of glaucoma and as a therapeutic target to prevent glaucoma progression,” the authors wrote.

SOURCE:

This study was led by Angela L. Beros, MPH, of the School of Population Health at the University of Auckland, Auckland, New Zealand, and published online in the American Journal of Ophthalmology.

LIMITATIONS:

The cohort study did not clinically assess for glaucoma, potentially leading to the inclusion of individuals with the condition. Not all participants with incident glaucoma, particularly those unaware of their diagnosis, may have been identified. Intraocular pressure and central corneal thickness, which are common risk factors for glaucoma, were not included in the multivariate analysis.

DISCLOSURES:

The study did not receive any funding. The authors declared no conflicts of interest.

Women who used levonorgestrel-releasing intrauterine devices (LG-IUDs) were 22% less likely to have a stroke than those who did not use hormonal contraception, new research suggested.

The Danish study, which included 1.7 million women, also showed no increased risk for intracerebral hemorrhage for those using the IUDs.

“The finding raises the question of whether levonorgestrel, in addition to its contraceptive properties, could have the potential to prevent (ischemic stroke),” wrote corresponding author Tom Skyhøj Olsen, MD, PhD, of Bispebjerg University Hospital, Copenhagen, Denmark, and coauthors.

The research was published online on May 16, 2024, in the journal Stroke.
 

A Big-Picture Look

Commonly used combined hormonal contraceptives that contain both progestins and ethinylestradiol are linked to an increased risk for ischemic stroke. Previous research suggested that progestin-only options, including LG-IUDs, are not associated with elevated risk and may even lower the risk. The IUDs had also been previously associated with lower risk for thromboembolism.

The new study was a large-scale investigation of all reproductive-age women in Denmark that compared stroke risk in those who used the progestin-only IUDs with those who didn’t use hormonal contraception. It also examined the risk for intracerebral hemorrhage, which had not been previously studied.

The historic cohort study drew on several large national databases in Denmark, including the Danish Stroke Registry, to evaluate the interplay between IUD contraception, stroke, and intracerebral hemorrhage. The study looked back at data collected on all nonpregnant Danish women aged 18-49 years who lived in Denmark for some or all of the period between 2004 and 2021.

Mean age of the 1.7 million women in the study was 30 years, and the mean follow-up period was about 7 years. More than 364,700 participants used LG-IUDs.

During the study period, 2916 women had an ischemic stroke, and 367 experienced intracerebral hemorrhage.

Among IUD users, the incidence of stroke was 19.2 per 100,000 person years. For women who didn’t use contraception, the rate was 25.2.

Overall, those who used an IUD had a 22% lower risk for ischemic stroke than those who didn’t (incidence rate ratio [IRR], 0.78; 95% CI, 0.70-0.88).

The incidence of brain bleeds was similar in both groups.

Does Age Matter?

The incidence of stroke did not differ significantly between the three age groups analyzed in the study: Women aged 18-29 years, 30-39 years, and 40-49 years. Incidence rates of intracerebral hemorrhage were similar between age groups 30-39 years and 40-49 years, but the risk was higher for those aged 18-29 years than for those aged 40-49 years (IRR, 4.49; 95% CI, 1.65-12.19).

The researchers urged caution in interpreting the apparent higher risk for brain bleeds in younger women, noting that the overall number of events was low, resulting in wide CIs.

Investigators also found that women who moved to Denmark from non-Western countries had a significantly lower stroke rate than native Danes. Incidence rates of intracerebral hemorrhage were not affected by country of origin.

The research team noted that they had only indirect information about women’s stroke risk factors including diabetes, high blood pressure, and migraine and had no information about smoking, alcohol consumption, and body mass index.

“Regarding a possible potential for stroke prevention, our study cannot stand alone and requires confirmation in further research. Even though the incidence rate for [ischemic stroke] and [intracerebral hemorrhage] did not significantly change after adjustment for various factors, bias…cannot be fully ruled out,” the researchers wrote.

The study was funded by the Aase og Ejnar Danielsens Fond and Familien Hede Nielsens Fond. The authors reported no relevant financial relationships.

The incidence of brain bleeds was similar in both groups.

Does Age Matter?

The incidence of stroke did not differ significantly between the three age groups analyzed in the study: Women aged 18-29 years, 30-39 years, and 40-49 years. Incidence rates of intracerebral hemorrhage were similar between age groups 30-39 years and 40-49 years, but the risk was higher for those aged 18-29 years than for those aged 40-49 years (IRR, 4.49; 95% CI, 1.65-12.19).

The researchers urged caution in interpreting the apparent higher risk for brain bleeds in younger women, noting that the overall number of events was low, resulting in wide CIs.

Investigators also found that women who moved to Denmark from non-Western countries had a significantly lower stroke rate than native Danes. Incidence rates of intracerebral hemorrhage were not affected by country of origin.

The research team noted that they had only indirect information about women’s stroke risk factors including diabetes, high blood pressure, and migraine and had no information about smoking, alcohol consumption, and body mass index.

“Regarding a possible potential for stroke prevention, our study cannot stand alone and requires confirmation in further research. Even though the incidence rate for [ischemic stroke] and [intracerebral hemorrhage] did not significantly change after adjustment for various factors, bias…cannot be fully ruled out,” the researchers wrote.

The study was funded by the Aase og Ejnar Danielsens Fond and Familien Hede Nielsens Fond. The authors reported no relevant financial relationships.

Women who used levonorgestrel-releasing intrauterine devices (LG-IUDs) were 22% less likely to have a stroke than those who did not use hormonal contraception, new research suggested.

The Danish study, which included 1.7 million women, also showed no increased risk for intracerebral hemorrhage for those using the IUDs.

“The finding raises the question of whether levonorgestrel, in addition to its contraceptive properties, could have the potential to prevent (ischemic stroke),” wrote corresponding author Tom Skyhøj Olsen, MD, PhD, of Bispebjerg University Hospital, Copenhagen, Denmark, and coauthors.

The research was published online on May 16, 2024, in the journal Stroke.
 

A Big-Picture Look

Commonly used combined hormonal contraceptives that contain both progestins and ethinylestradiol are linked to an increased risk for ischemic stroke. Previous research suggested that progestin-only options, including LG-IUDs, are not associated with elevated risk and may even lower the risk. The IUDs had also been previously associated with lower risk for thromboembolism.

The new study was a large-scale investigation of all reproductive-age women in Denmark that compared stroke risk in those who used the progestin-only IUDs with those who didn’t use hormonal contraception. It also examined the risk for intracerebral hemorrhage, which had not been previously studied.

The historic cohort study drew on several large national databases in Denmark, including the Danish Stroke Registry, to evaluate the interplay between IUD contraception, stroke, and intracerebral hemorrhage. The study looked back at data collected on all nonpregnant Danish women aged 18-49 years who lived in Denmark for some or all of the period between 2004 and 2021.

Mean age of the 1.7 million women in the study was 30 years, and the mean follow-up period was about 7 years. More than 364,700 participants used LG-IUDs.

During the study period, 2916 women had an ischemic stroke, and 367 experienced intracerebral hemorrhage.

Among IUD users, the incidence of stroke was 19.2 per 100,000 person years. For women who didn’t use contraception, the rate was 25.2.

Overall, those who used an IUD had a 22% lower risk for ischemic stroke than those who didn’t (incidence rate ratio [IRR], 0.78; 95% CI, 0.70-0.88).
