Patients with atopic dermatitis (AD) had a lower risk for major adverse cardiovascular events (MACE) than the general population, and this risk was significantly lower than that of patients with rheumatoid arthritis (RA), according to an analysis of national claims data.

The results of the analysis were presented during a poster session at the Revolutionizing Atopic Dermatitis conference in Chicago. “While it is known that atopic dermatitis is associated with some comorbidities, the specific risk of major adverse cardiovascular events in patients with AD, especially those with moderate to severe AD within the US population, is unclear,” the study’s first author Christopher G. Bunick, MD, PhD, said in an interview following the conference.

To characterize the risk for MACE in patients with AD vs matched controls without AD (non-AD) and patients with RA, Dr. Bunick, associate professor of dermatology at Yale University, New Haven, Connecticut, and colleagues retrospectively evaluated US claims data from Optum’s Clinformatics Data Mart. The study population consisted of 381,221 patients aged 18 years and older who were diagnosed with AD from March 2017 to March 2023. Comparator groups included 381,221 non-AD controls matched by age, sex, and cohort entry, and 97,445 patients diagnosed with RA based on at least two claims for RA ≥ 7 days apart.

Patients were classified as having moderate to severe disease if they received dupilumab for AD or advanced systemic therapy for RA at any time during the follow-up period. The matched moderate to severe AD and non-AD cohorts were composed of 7134 patients each. The incidence of MACE was defined as inpatient hospitalization with myocardial infarction or stroke. The researchers used multivariable Cox proportional hazard models adjusted for baseline demographics, comorbidities, and medications to calculate the relative risk for MACE.
 

MACE Incidence, Relative Risk

The mean age of the AD cohort and non-AD matched controls was 58 years, and the mean age of the RA cohort was 67 years. The incidence of MACE per 100 patient-years was 1.78 among patients with AD, 1.83 among non-AD matched controls, and 2.12 among patients with RA. Patients with moderate to severe AD had a MACE incidence of 1.18 per 100 patient-years, which was lower than that of non-AD matched controls (1.52) and patients with moderate to severe RA (1.67).

In other findings, the relative risk for MACE in patients with AD was lower vs non-AD controls (adjusted hazard ratio [aHR], 0.91; 95% CI, 0.89-0.93; P < .001) and patients with RA (aHR, 0.83; 95% CI, 0.80-0.85; P < .001). Among patients with moderate to severe AD, MACE risk was similar to that of non-AD matched controls (aHR, 0.92; 95% CI, 0.73-1.14) and lower vs those with moderate to severe RA (aHR, 0.83; 95% CI, 0.73-0.94; P < .01).

MACE risk associated with AD was greater in patients who were older (per year, aHR, 1.05; 95% CI, 1.05-1.05), male (aHR, 0.81; 95% CI, 0.79-0.84), and Black vs White (aHR, 1.16; 95% CI, 1.11-1.21), and among those who received systemic corticosteroids in the 3 months before diagnosis (aHR, 1.10; 95% CI, 1.06-1.14), were hospitalized in the year before diagnosis (aHR, 1.35; 95% CI, 1.30-1.41), and had a history of smoking (aHR, 1.20; 95% CI, 1.16-1.24) and drug abuse (aHR, 1.34; 95% CI, 1.25-1.43).
 

Unexpected Results

“One surprising finding was that the incidence of MACE in patients with moderate to severe AD was actually lower than that in non-AD matched controls and significantly lower compared to patients with moderate to severe RA,” Dr. Bunick said. “This contrasts with the expectation that increased systemic inflammation in moderate to severe AD would correspond with a higher incidence of MACE.”

Another unexpected result, he said, was that, among patients with moderate to severe AD, the risk for MACE was not significantly different from that of non-AD matched controls, suggesting that the inflammatory burden in AD might not translate to as high a cardiovascular risk as previously assumed.

Dr. Bunick noted that advanced treatments for AD such as Janus kinase (JAK) inhibitors (upadacitinib and abrocitinib) have a class boxed warning for MACE based on a study of another JAK inhibitor (tofacitinib) in patients with RA, but “this may not apply to AD because patients with AD have a lower risk for MACE.”

In his opinion, he said, the study “underscores the importance of understanding the specific risks associated with different inflammatory conditions.” Moreover, “it emphasizes the potential benefits of newer systemic therapies in potentially mitigating cardiovascular risks in patients with moderate to severe AD.”

Dr. Bunick acknowledged certain limitations of the study, including its retrospective design and reliance on administrative claims data, which “may introduce coding errors and misclassification,” and the generalizability of the results, which may be limited to the US population.

AbbVie funded the study, and three of the coauthors are employees of the company. Dr. Bunick disclosed that he has served as an investigator and/or a consultant for AbbVie, Almirall, Apogee, Arcutis Biotherapeutics, Connect Biopharma, Daiichi Sankyo, EPI Health/Novan, LEO, Lilly, Novartis, Ortho Dermatologics, Palvella Therapeutics, Pfizer, Sanofi Regeneron, Sun, Takeda, Timber, and UCB.

In the United States, the prevalence of patient-reported atopic dermatitis (AD) is higher in children and adult women, while Hispanic adults have a lower prevalence of AD than adults from other ethnic backgrounds.

Those are among the key findings from an analysis of nationally representative cross-sectional data that were presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis conference in Chicago.

“In the past few years, there has been a much-needed focus on better understanding disparities in atopic dermatitis,” one of the study authors, Raj Chovatiya, MD, PhD, clinical associate professor at Chicago Medical School, Rosalind Franklin University, North Chicago, told this news organization after the conference.

Dr. Chovatiya

“Epidemiology is one of the key ways in which we can query differences in AD at a population level.”

Drawing from the 2021 National Health Interview Survey, the researchers identified 3103 respondents who reported being diagnosed with AD or eczema. They estimated the prevalence rates of AD for the overall population and each subgroup by dividing US frequency estimates by their corresponding US population totals and used multivariable logistic regression to assess the odds of having AD.

More than half of the respondents (1643) were aged between 18 and 64 years, 522 were aged 65 years and older, and 922 were children younger than 18 years. Overall, the prevalence of AD was 7.6% in adults aged 18-64 years and 6.1% in adults aged 65 years and older, for a weighted US estimate of 15.3 and 3.2 million, respectively. The prevalence of AD varied by race/ethnicity and was highest for those from “other single and multiple races” group (12.4%), followed by Black/African American (8.5%), White (7.7%), Asian (6.5%), American Indian/Alaskan Native (4.9%), and Hispanic (4.8%) populations.

In children, race/ethnicity prevalence were highest for those from other single and multiple races (15.2.%), followed by Black/African American (14.2%), American Indian/Alaskan Native (12%), White (10.2%), Hispanic (9.5%), and Asian (9%) populations.

When the researchers combined all age groups, they observed higher prevalence rates of AD among females than among males. However, in an analysis limited to children, the prevalence rates were similar between girls and boys (10.8% vs 10.7%, respectively), for a weighted US estimate of 7.8 million children with AD.

On multiple regression, the odds of having AD were greater among women than among men (odds ratio [OR], 1.4), among adults aged 18-64 years than among those aged 65 years and older (OR, 1.4), among those younger than 18 years than among those aged 65 years and older (OR, 2.0), and among Black/African American individuals than among White individuals (OR, 1.2). Hispanic adults had a lower risk for AD than non-Hispanic White adults (OR, 0.69) as did Asian adults than White adults (OR, 0.82).

“We found AD prevalence rates were higher in children and adult females, Hispanic adults had a lower prevalence of AD than all other adult groups, and there were numerical differences in AD prevalence across racial groups,” Dr. Chovatiya said in the interview. “While there are of course limitations to the use of any nationally representative cross-sectional dataset that requires weighting to project results from a smaller sample to reflect a larger more heterogeneous group, these results are important for us to consider targeted strategies to address AD burden.”

Jonathan I. Silverberg, MD, PhD, professor of dermatology at The George Washington University, Washington, who was asked to comment on the study, said that while the prevalence of AD in children has been well documented in prior research, “this study fills an important gap by showing us that the prevalence does remain high in adults.”

In addition, “it has not shown any evidence of AD decreasing over time; if anything, it might be slightly increasing,” he said. “We’re also seeing differences [in AD] by race and ethnicity. We have seen that demonstrated in children but [has been] less clearly demonstrated in adults.”

Eli Lilly and Company funded the analysis. Dr. Chovatiya and Dr. Silverberg disclosed ties to several pharmaceutical companies, including Eli Lilly.

Treatment with topical ruxolitinib cream 1.5% showed good tolerability and was effective over the course of 52 weeks in children aged 2-11 years with atopic dermatitis (AD) affecting ≥ 35% or more of their body surface area (BSA), results from a small open-label maximum-use trial showed.

When approved for this age group, ruxolitinib cream will provide a topical nonsteroidal option for patients aged 2-11, which will “simplify the treatment regimen,” one of the study investigators, Linda Stein Gold, MD, director of clinical research and division head of dermatology at the Henry Ford Health System, Detroit, said in an interview after the Revolutionizing Atopic Dermatitis conference, where the study was presented during a late-breaking abstract session.

Dr. Stein Gold

A topical formulation of the selective Janus kinase (JAK) 1/JAK2 inhibitor, ruxolitinib cream 1.5% is currently approved by the Food and Drug Administration for the short-term and noncontinuous chronic treatment of mild to moderate AD in non-immunocompromised adult and pediatric patients aged 12 years and older, whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable.

In previous reports of this trial in children aged 2-11 years with ≥ 35% affected BSA, ruxolitinib cream 1.5% was generally well tolerated, with rapid anti-inflammatory and antipruritic effects and improvements in patient-reported outcomes observed with ≤ 4 weeks of continuous treatment and maintained with as-needed treatment from 4 to 8 weeks.

For the current trial, investigators evaluated data on tolerability, safety, systemic exposure, and clinical and patient-reported outcomes through 52 weeks to determine whether clinical benefits and tolerability observed through 8 weeks were sustained.

Dr. Stein Gold and colleagues reported results from 29 children who received ruxolitinib cream 1.5% from baseline through week 8. Of these, 22 continued into the long-term safety period from week 8 through 52. From baseline through week 8, patients applied a mean of 6.5 g per day of ruxolitinib cream; this dropped to a mean of 3.2 g per day from weeks 8 through 52. The mean steady-state plasma concentration of ruxolitinib throughout the study was 98.2 nM, which is “well below half-maximal concentration of JAK-mediated myelosuppression in adults (281 nM),” the researchers stated in their abstract.

No treatment-related interruptions, discontinuations, or serious adverse events were observed between baseline and week 52. One patient (3.4%) had two treatment-related application site reactions (paresthesia and folliculitis). At weeks 4 and 52, 53.8% of patients achieved treatment success, which was defined as an Investigator Global Assessment of 0/1 with a ≥ 2-grade improvement from baseline. The mean affected BSA decreased from 58.0% at baseline to 11.4% at week 4 and continued to decrease to 2.2% through week 52. “I was surprised that patients could maintain control over the long-term using the medication as needed,” Dr. Stein Gold told this news organization. “I was also pleased to see that there was low systemic exposure even when used on large body surface areas.”

In other findings, the mean total Patient Oriented Eczema Measure score dropped from a baseline of 19.4 to a mean of 4.5 at week 8 and 3.6 at week 52 and the mean total Children’s Dermatology Life Quality Index score fell from a baseline of 15.4 to a mean of 5.3 at week 8 and a mean of 2.1 at week 52. Meanwhile, the mean total Infants’ Dermatology Quality of Life Index score fell from a mean of 12.3 at baseline to a mean of 2.8 at week 8 and a mean of 0.7 at week 52.

Dr. Stein Gold noted certain limitations of the study, including the fact that it did not study children aged younger than 2 years.

The study was funded by Incyte, which markets ruxolitinib cream 1.5% as Opzelura. Dr. Stein Gold disclosed that she has served as an investigator, advisor, and/or speaker for several pharmaceutical companies, including Incyte.

Treatment with topical ruxolitinib cream 1.5% showed good tolerability and was effective over the course of 52 weeks in children aged 2-11 years with atopic dermatitis (AD) affecting ≥ 35% or more of their body surface area (BSA), results from a small open-label maximum-use trial showed.

When approved for this age group, ruxolitinib cream will provide a topical nonsteroidal option for patients aged 2-11, which will “simplify the treatment regimen,” one of the study investigators, Linda Stein Gold, MD, director of clinical research and division head of dermatology at the Henry Ford Health System, Detroit, said in an interview after the Revolutionizing Atopic Dermatitis conference, where the study was presented during a late-breaking abstract session.

Dr. Stein Gold

A topical formulation of the selective Janus kinase (JAK) 1/JAK2 inhibitor, ruxolitinib cream 1.5% is currently approved by the Food and Drug Administration for the short-term and noncontinuous chronic treatment of mild to moderate AD in non-immunocompromised adult and pediatric patients aged 12 years and older, whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable.

In previous reports of this trial in children aged 2-11 years with ≥ 35% affected BSA, ruxolitinib cream 1.5% was generally well tolerated, with rapid anti-inflammatory and antipruritic effects and improvements in patient-reported outcomes observed with ≤ 4 weeks of continuous treatment and maintained with as-needed treatment from 4 to 8 weeks.

For the current trial, investigators evaluated data on tolerability, safety, systemic exposure, and clinical and patient-reported outcomes through 52 weeks to determine whether clinical benefits and tolerability observed through 8 weeks were sustained.

Dr. Stein Gold and colleagues reported results from 29 children who received ruxolitinib cream 1.5% from baseline through week 8. Of these, 22 continued into the long-term safety period from week 8 through 52. From baseline through week 8, patients applied a mean of 6.5 g per day of ruxolitinib cream; this dropped to a mean of 3.2 g per day from weeks 8 through 52. The mean steady-state plasma concentration of ruxolitinib throughout the study was 98.2 nM, which is “well below half-maximal concentration of JAK-mediated myelosuppression in adults (281 nM),” the researchers stated in their abstract.

No treatment-related interruptions, discontinuations, or serious adverse events were observed between baseline and week 52. One patient (3.4%) had two treatment-related application site reactions (paresthesia and folliculitis). At weeks 4 and 52, 53.8% of patients achieved treatment success, which was defined as an Investigator Global Assessment of 0/1 with a ≥ 2-grade improvement from baseline. The mean affected BSA decreased from 58.0% at baseline to 11.4% at week 4 and continued to decrease to 2.2% through week 52. “I was surprised that patients could maintain control over the long-term using the medication as needed,” Dr. Stein Gold told this news organization. “I was also pleased to see that there was low systemic exposure even when used on large body surface areas.”

A story in a recent edition of this newspaper reported on a disturbing, but not surprising, study by a third-year pediatric resident at the University of California, Davis, School of Medicine. Looking at just the Preparticipaton Physical Evaluations (PPEs) she could find at her institution, Tammy Ng, MD, found that only slightly more than a quarter “addressed all the criteria” on the American Academy of Pediatrics (AAP) standardized form. Although more than half included inquiries about respiratory symptoms, less than half contained questions about a cardiovascular history. The lack of consistency across all the forms reviewed was the most dramatic finding.

Having participated in more than my share of PPEs as a school physician, a primary care pediatrician, and a multi-sport high school and college athlete, I was not surprised by Dr. Ng’s findings. In high school my teammates and I considered our trip to see Old Doctor Hinds (not his real name) in the second week of August “a joke.” A few of us with “white coat” hypertension, like myself, had to be settled down and have our blood pressure retaken. But other than that wrinkle, we all passed. The football coach had his own eyeball screening tool and wouldn’t allow kids he thought were too small to play football.

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

TOPLINE:

Pediatric patients with atopic dermatitis (AD) who are prescribed dupilumab may be at a reduced risk for atopic march progression, defined as the development of asthma or allergic rhinitis.

METHODOLOGY:

• Researchers conducted a retrospective cohort study using data from the US Collaborative Network, focusing on pediatric patients aged 18 years and younger with two AD diagnoses at least 30 days apart.
• Patients were divided into two cohorts: Those treated with dupilumab (n = 2192) and those who received conventional therapies (n = 2192), including systemic corticosteroids or conventional immunomodulators. They were stratified into three age groups: Preschoolers (< 6 years), school-aged children (6 to < 12 years), and adolescents (12-18 years).
• Both cohorts underwent 1:1 propensity score matching based on current age, age at index (first prescription of dupilumab or conventional therapy), sex, race, comorbidities, laboratory measurements, and prior medications. The primary outcome was atopic march progression, defined by incident asthma or allergic rhinitis.

TAKEAWAY:

• Over 3 years, the dupilumab-treated cohort had a significantly lower cumulative incidence of atopic march progression (20.09% vs 27.22%; P < .001), asthma (9.43% vs 14.64%; P = .001), and allergic rhinitis (13.57% vs 20.52%; P = .003) than the conventional therapy cohort.
• The risk for atopic march progression, asthma, and allergic rhinitis was also significantly reduced by 32%, 40%, and 31%, respectively, in the dupilumab vs conventional therapy cohort.
• Age-specific analyses found that the protective effect of dupilumab against allergic rhinitis was the most pronounced in adolescents (hazard ratio [HR], 0.503; 95% CI, 0.322-0.784), followed by school-aged children (HR, 0.577; 95% CI, 0.399-0.834), and preschoolers (HR, 0.623; 95% CI, 0.412-0.942).
• However, dupilumab was associated with reduced risk for asthma only in preschoolers (HR, 0.427; 95% CI, 0.247-0.738) and not in school-aged children or adolescents.

IN PRACTICE:

“Dupilumab in AD not only treats the disease but may influence atopic march mechanisms, suggesting its role as a disease-modifying atopic march drug,” the authors wrote, adding that more research “with extended follow-up and proof-of-concept is warranted.”

SOURCE:

The study was led by Teng-Li Lin, MD, Department of Dermatology, Dalin Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Chiayi, Taiwan, and was published online on June 13, 2024, in the Journal of the American Academy of Dermatology.

LIMITATIONS:

The observational nature of the study limited the ability to infer direct causality between dupilumab use and reduced atopic march risk. Lack of detailed information on AD severity, total dosage, and duration of medication treatment may affect the interpretation of the study’s findings. The demographic data suggest that the dupilumab cohort had more severe AD, so the observed risk reduction may be greater than that reported in this study.

DISCLOSURES:

The study was supported in part by the National Science and Technology Council, Taiwan, and Taichung Veterans General Hospital. The authors had no relevant conflicts of interest.

An updated Cochrane Systematic Review of magnesium sulfate administered before preterm birth for neuroprotection has reaffirmed that the compound significantly reduces the risk of cerebral palsy and has added the finding that it also may reduce the risk of severe neonatal intraventricular hemorrhage.

Still unknown, however, is whether the effects of magnesium sulfate vary according to patient characteristics such as gestational age, or by treatment characteristics such as timing and dose. “We need further research to determine exactly who to treat, and when and how, to ideally standardize clinical practice recommendations across the world,” said Emily S. Shepherd, PhD, lead author of the review.

Magnesium sulfate is widely used for preterm cerebral palsy prevention but variance in national and local recommendations for its use may impede its optimal uptake in some places, she and her co-investigators wrote in the review.

In the United States, the American College of Obstetricians and Gynecologists advises institutions to develop their own guidelines regarding inclusion criteria and treatment regimens “in accordance with one of the larger trials.” (ACOG’s Committee Opinion on Magnesium Sulfate Before Anticipated Preterm Birth for Neuroprotection was originally published in 2010 and was reaffirmed in 2023.)

In a Master Class column on magnesium sulfate for neuroprotection published earlier this year in Ob.Gyn. News, Irina Burd, MD, PhD, wrote that most hospitals in the United States have chosen a higher dose of magnesium sulfate administered up to 31 weeks’ gestation (6-g bolus, followed by 2 g/hour), in keeping with the protocols used in the BEAM trial published by the National Institute of Child Health and Human Development (NICHD). Dr. Burd is the Sylvan Frieman, MD, Endowed Professor and chair of the department of obstetrics, gynecology and reproductive sciences at the University of Maryland School of Medicine, Baltimore, Maryland.

The new Cochrane review included six randomized controlled trials (including the NICHD trial) covering 5917 pregnant participants and 6759 fetuses. Eligibility criteria varied, but all the RCTs included patients in preterm labor or with expected or planned imminent preterm birth at less than 34 weeks’ gestation.

Treatment regimens varied: three trials administered a 4-g loading dose only, and three included a maintenance dose (a 4-6-g loading dose and a 1-2 g/hour maintenance dose). “Although we attempted to explore variation through subgroup analyses, the ability to do this was limited,” the researchers wrote.

Up to 2 years of corrected age, magnesium sulfate reduced the risk of cerebral palsy compared with placebo (relative risk, 0.71; 95% confidence interval (CI), 0.57-0.89) and death or cerebral palsy (RR, 0.87; 95% CI, 0.77-0.98), with a high-certainty grade of evidence. The number needed to treat to prevent one case of cerebral palsy was 60 and the number needed to treat death or cerebral palsy was 56. The impact on severe intracranial hemorrhage (RR, 0.76; 95% CI, 0.60-0.98), a secondary outcome, was backed by moderate-certainty evidence.

Compared with the 2009 Cochrane review, the new study includes two new randomized controlled trials. One of which, the MAGENTA trial, administered magnesium sulfate at 30-34 weeks gestation and included new school-age follow-up data from two previously included trials. While the available data suggest little to no difference in outcomes at school age, more follow-up data are needed to assess this with greater certainty, the reviewers wrote.

While severe adverse outcomes (death, cardiac or respiratory arrest) for pregnant individuals appear not to have increased in pregnant patients who received magnesium sulfate (low-certainty evidence), the compound “probably increased maternal adverse effects severe enough to stop treatment,” the reviewers report (average RR, 3.21; 95% CI, 1.88-5.48; moderate-certainty evidence).

Side effects that were more frequent among women receiving magnesium sulfate include hypotension, tachycardia, warmth over body/flushing, nausea or vomiting, sweating, and dizziness.

“Treatment cessation due to such side effects was in the context of trials being conducted to establish benefit,” noted Dr. Shepherd, of the University of Adelaide in Australia. “With benefit now shown, these side effects may be viewed as comparatively minor/generally tolerable considering the potential benefits for children.”

Proving the neuroprotective value of magnesium sulfate took many years, Dr. Burd explained in the Master Class, as none of the randomized controlled trials analyzed in eventual meta-analyses and systematic reviews had reached their primary endpoints. It wasn’t until researchers obtained unpublished data and conducted these analyses and reviews that a significant effect of magnesium sulfate on cerebral palsy could be seen. Dr. Burd and other researchers are now working to better understand its biologic plausibility and precise mechanisms of action.

Dr. Shepherd disclosed that she is a former editor for Cochrane Pregnancy and Childbirth and current sign-off editor for Cochrane Central Editorial Service but reported having no involvement in the editorial processing of the review. Other authors disclosed that they were investigators for included trials and/or have published opinions in medical journals related to magnesium sulfate to reduce cerebral palsy. Dr. Burd reported no disclosures.

While severe adverse outcomes (death, cardiac or respiratory arrest) for pregnant individuals appear not to have increased in pregnant patients who received magnesium sulfate (low-certainty evidence), the compound “probably increased maternal adverse effects severe enough to stop treatment,” the reviewers report (average RR, 3.21; 95% CI, 1.88-5.48; moderate-certainty evidence).

Side effects that were more frequent among women receiving magnesium sulfate include hypotension, tachycardia, warmth over body/flushing, nausea or vomiting, sweating, and dizziness.

“Treatment cessation due to such side effects was in the context of trials being conducted to establish benefit,” noted Dr. Shepherd, of the University of Adelaide in Australia. “With benefit now shown, these side effects may be viewed as comparatively minor/generally tolerable considering the potential benefits for children.”

Proving the neuroprotective value of magnesium sulfate took many years, Dr. Burd explained in the Master Class, as none of the randomized controlled trials analyzed in eventual meta-analyses and systematic reviews had reached their primary endpoints. It wasn’t until researchers obtained unpublished data and conducted these analyses and reviews that a significant effect of magnesium sulfate on cerebral palsy could be seen. Dr. Burd and other researchers are now working to better understand its biologic plausibility and precise mechanisms of action.

Dr. Shepherd disclosed that she is a former editor for Cochrane Pregnancy and Childbirth and current sign-off editor for Cochrane Central Editorial Service but reported having no involvement in the editorial processing of the review. Other authors disclosed that they were investigators for included trials and/or have published opinions in medical journals related to magnesium sulfate to reduce cerebral palsy. Dr. Burd reported no disclosures.

An updated Cochrane Systematic Review of magnesium sulfate administered before preterm birth for neuroprotection has reaffirmed that the compound significantly reduces the risk of cerebral palsy and has added the finding that it also may reduce the risk of severe neonatal intraventricular hemorrhage.

Still unknown, however, is whether the effects of magnesium sulfate vary according to patient characteristics such as gestational age, or by treatment characteristics such as timing and dose. “We need further research to determine exactly who to treat, and when and how, to ideally standardize clinical practice recommendations across the world,” said Emily S. Shepherd, PhD, lead author of the review.

Magnesium sulfate is widely used for preterm cerebral palsy prevention but variance in national and local recommendations for its use may impede its optimal uptake in some places, she and her co-investigators wrote in the review.

In the United States, the American College of Obstetricians and Gynecologists advises institutions to develop their own guidelines regarding inclusion criteria and treatment regimens “in accordance with one of the larger trials.” (ACOG’s Committee Opinion on Magnesium Sulfate Before Anticipated Preterm Birth for Neuroprotection was originally published in 2010 and was reaffirmed in 2023.)

In a Master Class column on magnesium sulfate for neuroprotection published earlier this year in Ob.Gyn. News, Irina Burd, MD, PhD, wrote that most hospitals in the United States have chosen a higher dose of magnesium sulfate administered up to 31 weeks’ gestation (6-g bolus, followed by 2 g/hour), in keeping with the protocols used in the BEAM trial published by the National Institute of Child Health and Human Development (NICHD). Dr. Burd is the Sylvan Frieman, MD, Endowed Professor and chair of the department of obstetrics, gynecology and reproductive sciences at the University of Maryland School of Medicine, Baltimore, Maryland.

The new Cochrane review included six randomized controlled trials (including the NICHD trial) covering 5917 pregnant participants and 6759 fetuses. Eligibility criteria varied, but all the RCTs included patients in preterm labor or with expected or planned imminent preterm birth at less than 34 weeks’ gestation.

Treatment regimens varied: three trials administered a 4-g loading dose only, and three included a maintenance dose (a 4-6-g loading dose and a 1-2 g/hour maintenance dose). “Although we attempted to explore variation through subgroup analyses, the ability to do this was limited,” the researchers wrote.

Up to 2 years of corrected age, magnesium sulfate reduced the risk of cerebral palsy compared with placebo (relative risk, 0.71; 95% confidence interval (CI), 0.57-0.89) and death or cerebral palsy (RR, 0.87; 95% CI, 0.77-0.98), with a high-certainty grade of evidence. The number needed to treat to prevent one case of cerebral palsy was 60 and the number needed to treat death or cerebral palsy was 56. The impact on severe intracranial hemorrhage (RR, 0.76; 95% CI, 0.60-0.98), a secondary outcome, was backed by moderate-certainty evidence.

Compared with the 2009 Cochrane review, the new study includes two new randomized controlled trials. One of which, the MAGENTA trial, administered magnesium sulfate at 30-34 weeks gestation and included new school-age follow-up data from two previously included trials. While the available data suggest little to no difference in outcomes at school age, more follow-up data are needed to assess this with greater certainty, the reviewers wrote.

PARIS — Pregnancy is a period of asthma instability; it entails an increased risk for exacerbations. While therapeutic de-escalation, if not the outright cessation of maintenance treatment, is common, experts used the 19th Francophone Congress of Allergology to emphasize the importance of well-controlled asthma for the mother, the fetus, and the pregnancy.

About 12% of women of childbearing age have asthma. It is the most common chronic condition in pregnant women. Pregnancy affects asthma, and vice versa. Due to mechanical, hormonal, and immunological changes, allergic conditions, including asthma, can worsen.

First, pregnancy exerts mechanical pressure on respiratory function because of the progressive increase in uterine volume, diaphragm elevation, and various anatomical changes leading to chest expansion. The latter changes include increased subcostal angle, anteroposterior and transverse diameters, and thoracic circumference. 

Respiratory function is affected, with a decrease in functional residual capacity and expiratory reserve volume but an increase in inspiratory capacity, maximal ventilation, and tidal volume. The resulting hyperventilation manifests clinically as dyspnea, which affects up to 70% of pregnant women and can be mistaken for exacerbation symptoms.

Besides mechanical impact, hormonal changes occur during pregnancy, including elevated estrogen and progesterone levels. Placental hormones increase during the third trimester. These steroid hormones weaken the respiratory mucosa through structural changes in the bronchial wall and the activity of inflammatory cells involved in asthma, while influencing bronchial muscle tone. Estrogens have a dual effect. They are immunostimulatory at low doses and immunosuppressive at high doses (as in late pregnancy). This phenomenon suggests a role in immune tolerance toward the fetus.
 

The Rule of Thirds

Asthma progression during pregnancy is unpredictable. According to older studies, about one third of cases remain stable, one third worsen, and one third improve. In 60% of cases, the course remains similar from one pregnancy to another. Pregnancy is considered a period of asthma instability, with a doubled risk for exacerbation compared with nonpregnant women. Several pregnancy-specific factors contribute, including gastroesophageal reflux, excessive weight gain, active or passive smoking, and usual risk factors like infections. However, the main risk factor for exacerbation and loss of asthma control is insufficient maintenance treatment.

“The control of asthma during pregnancy is influenced by pregnancy itself, but especially by the severity of the disease before pregnancy and the underuse of inhaled corticosteroids,” said Mohammed Tawfik el Fassy Fihry, MD, pulmonologist at Ibn Sina Souissi Hospital in Rabat, Morocco. “This treatment insufficiency is the main cause of poor asthma control and sometimes of severe exacerbations.”
 

Inhaled Corticosteroid Often Insufficient

A 2017 study conducted in France found that one third of women had their asthma treatment reduced in the first trimester of pregnancy. Another observation was the frequent replacement of fixed combinations (such as long- and short-acting bronchodilators and inhaled corticosteroids) with simple inhaled corticosteroid therapy.

“A significant proportion of pregnant women on maintenance therapy decide to stop it as soon as they discover their pregnancy,” said Chantal Raherison-Semjen, PhD, coordinator of the Women and Lung group of the French Society of Pulmonology (SPLF) and of the pulmonology department at the University Hospital of Pointe-à-Pitre in Guadeloupe, France. “Treating physicians also often opt for therapeutic de-escalation, which involves stopping long-acting bronchodilators in favor of only inhaled corticosteroid therapy, which is usually insufficient for optimal asthma control.”

In severe exacerbations, especially during the first trimester of pregnancy, poorly controlled asthma can lead to complications in fetal development, such as low birth weight, intrauterine growth retardation, prematurity, and congenital malformations.

It can also affect maternal health by increasing the risk for gestational diabetes and affecting the course of pregnancy itself, favoring the occurrence of preeclampsia, placenta previa, placental abruption, premature rupture of membranes, spontaneous miscarriage, cesarean section, and hemorrhagic complications before and after delivery.

“When a pregnant woman presents to the emergency room due to an asthma exacerbation, physicians are often reluctant to administer optimal treatment for fear of the effects of bronchodilators and systemic corticosteroids,” said Dr. Raherison-Semjen. “As a result, these women generally receive less effective treatment in such situations, compared with nonpregnant women. This is despite the risk that severe asthma exacerbations pose to the mother and her child.”
 

‘Pregnant Woman’ Pictogram

In France, manufacturers of teratogenic or fetotoxic drugs are required to display a pictogram on the label indicating the danger for pregnant women or the fetus. The guidelines for this labeling are left to the discretion of the laboratories, however, which sometimes leads to unjustified warnings on the packaging of inhaled corticosteroids or emergency treatments. French medical societies were not consulted on this matter, which complicates prescriptions for pregnant asthmatic women, said Dr. Raherison-Semjen. The SPLF condemns the harmful effects of this decision.

Corticosteroids and Omalizumab

“Given the low, if any, risks associated with the main asthma treatments for the mother and fetus, continuing treatments started before conception is highly recommended,” said Dr. Raherison-Semjen. Inhaled corticosteroids, the cornerstone of asthma treatment, are the primary therapy, and the dosage can be adjusted as strictly necessary. “When properly managed, treatment generally allows for asthma control and reduces the risk for complications during pregnancy to the same level observed in the general population.”

Depending on asthma control levels, long-acting beta-2 agonists (eg, formoterol, salmeterol, and indacaterol) can be added, and possibly leukotriene antagonists. Before pregnancy, prescribed medications should be continued, including biologics prescribed for severe asthma. The exception is omalizumab, which can be started during pregnancy without risk.

For its part, allergen immunotherapy should also be maintained but without dose increases. Oral corticosteroids are reserved for severe exacerbations.

As specified by the GINA report of 2023, the benefits of active asthma treatment during pregnancy far outweigh the risks of usual asthma medications (Level A). This view is supported by reassuring data from the Reference Center for Teratogenic Agents. “There is no scientific-medical evidence justifying that pregnant women with asthma should not be treated the same way as when they are not pregnant,” said Dr. Raherison-Semjen.

TOPLINE:

A meta-analysis showed that the use of oral tranexamic acid along with the standard triple combination cream (TCC) reduces melasma severity and recurrence in patients with melasma, without increasing toxicity.

METHODOLOGY:

• Current treatments for melasma focus on inducing remission and preventing relapse. Tranexamic acid, an antifibrinolytic drug, has shown promise in recent studies, but its optimal use, either alone or as an adjunct to TCC, remains unclear.
• Researchers conducted a meta-analysis of four randomized controlled trials patients that compared oral tranexamic acid plus TCC (hydroquinone, retinoic acid, and hydrocortisone) and TCC alone in 480 patients with melasma, divided almost evenly into the two treatment groups.
• The main outcome was the change in the Melasma Severity Area Index (MASI) score and recurrence rate from baseline.

TAKEAWAY:

• Patients treated with oral tranexamic acid plus TCC showed a greater reduction in MASI scores compared with those who received TCC alone (mean difference, −3.10; P = .03).
• The recurrence rate of melasma was significantly lower in the tranexamic acid plus TCC group (risk ratio [RR], 0.28; P < .001).
• There was no significant difference in the incidences of erythema (RR, 0.63; P = .147) and burning (RR, 0.59; P = .131).

IN PRACTICE:

“Evidence indicates that oral tranexamic acid confers clinical benefits, contributing to the enhancement of treatment outcomes in melasma when used in conjunction with TCC therapy,” and results are promising with regards to minimizing recurrence, the authors concluded.

SOURCE:

The study was led by Ocílio Ribeiro Gonçalves, MS, of the Federal University of Piauí, Teresina, Brazil, and was published online on June 8, 2024, in Clinical and Experimental Dermatology.

LIMITATIONS:

There was heterogeneity across studies, including different methods of administration, treatment protocols (including dosage), and timing of treatment.

DISCLOSURES:

The study reported receiving no funding. The authors declared no conflicts of interest.

TOPLINE:

Lung cancer screening was associated with earlier-stage diagnoses and improved survival in a retrospective analysis of a large cohort with low screening uptake. 

METHODOLOGY:

• Randomized trials have shown a mortality benefit with low-dose CT screening to detect lung cancer, but the benefits in clinical practice remain unclear, and lung cancer screening uptake has been slow.
• In this study, researchers assessed the impact of lung cancer screening among Veteran Health Administration patients diagnosed with lung cancer between 2011 and 2018.
• The team evaluated lung cancer stage at diagnosis, lung cancer–specific survival, and overall survival in patients with lung cancer who did vs did not receive screening before their diagnosis.
• Statistical analyses included Cox regression modeling and inverse propensity weighting with lead-time bias adjustment.

TAKEAWAY:

• Among 57,919 individuals diagnosed with lung cancer during the study period, 2167 (3.9%) underwent screening with at least one low-dose CT before receiving their diagnosis. There were no significant differences in age, gender, or race among patients who had prior screening and those who did not.
• Screened patients had double the rate of stage I diagnoses compared with unscreened patients (52% vs 27%) and about one third the rate of stage IV diagnoses (11% vs 32%).
• Patients who received screening before their cancer diagnosis had better overall survival rates compared with unscreened patients. The overall survival rates were 81.2% vs 56.6% at 1 year, 69.9% vs 41.1% at 2 years, and 44.9% vs 22.3% at 5 years, respectively. Lung cancer–specific survival was also better: The survival rates were 82.5% vs 58.7% at 1 year, 74.3% vs 44.4% at 2 years, and 59.0% vs 29.7% at 5 years, respectively.
• A subset analysis of screening-eligible patients (defined as those between the ages of 50-88 who were smokers with a pack-year history of ≥ 20 years or former smokers who quit within 15 years) showed that among those who underwent National Comprehensive Cancer Network guideline-concordant treatment within 12 months of diagnosis, screening resulted in “substantial” reductions in all-cause mortality (adjusted hazard ratio [aHR], 0.79) and lung cancer–specific mortality (aHR, 0.61).

IN PRACTICE:

“These findings provide corroboration of the results of randomized [lung cancer screening] trials in clinical practice,” the authors wrote. “We hope that the striking association between [lung cancer screening], earlier stage diagnosis of lung cancer, and improved mortality spurs a more robust uptake of this life-saving intervention into clinical practice.”

SOURCE:

The study, led by Donna M. Edwards MD, PhD, of the University of Michigan School of Medicine, Ann Arbor, Michigan, was published online in Cancer.

LIMITATIONS:

The study was limited by its retrospective and correlative design, and the authors also were unable to assess whether lung cancer screening contributed to more subsequence procedures in screened vs unscreened patients.

DISCLOSURES:

The study was funded by the LUNGevity Foundation, US Department of Veterans Affairs, National Cancer Institute, and Lung Precision Oncology Program. One author declared being a consultant for industry. The other authors declared no conflicts of interest.

TOPLINE:

Lung cancer screening was associated with earlier-stage diagnoses and improved survival in a retrospective analysis of a large cohort with low screening uptake. 

METHODOLOGY:

• Randomized trials have shown a mortality benefit with low-dose CT screening to detect lung cancer, but the benefits in clinical practice remain unclear, and lung cancer screening uptake has been slow.
• In this study, researchers assessed the impact of lung cancer screening among Veteran Health Administration patients diagnosed with lung cancer between 2011 and 2018.
• The team evaluated lung cancer stage at diagnosis, lung cancer–specific survival, and overall survival in patients with lung cancer who did vs did not receive screening before their diagnosis.
• Statistical analyses included Cox regression modeling and inverse propensity weighting with lead-time bias adjustment.

TAKEAWAY:

• Among 57,919 individuals diagnosed with lung cancer during the study period, 2167 (3.9%) underwent screening with at least one low-dose CT before receiving their diagnosis. There were no significant differences in age, gender, or race among patients who had prior screening and those who did not.
• Screened patients had double the rate of stage I diagnoses compared with unscreened patients (52% vs 27%) and about one third the rate of stage IV diagnoses (11% vs 32%).
• Patients who received screening before their cancer diagnosis had better overall survival rates compared with unscreened patients. The overall survival rates were 81.2% vs 56.6% at 1 year, 69.9% vs 41.1% at 2 years, and 44.9% vs 22.3% at 5 years, respectively. Lung cancer–specific survival was also better: The survival rates were 82.5% vs 58.7% at 1 year, 74.3% vs 44.4% at 2 years, and 59.0% vs 29.7% at 5 years, respectively.

CHICAGO —The use of kratom, an opioid-like supplement widely available over the counter at convenience stores, smoke shops, and online, is resulting in emerging cases of hyperpigmentation, most often on the face and hands.

“This is something we will see more and more,” Heather Woolery-Lloyd, MD, director of the Skin of Color Division at the University of Miami Department of Dermatology, said at the Pigmentary Disorders Exchange Symposium. The key marker of this hyperpigmentation, she said, is that “it’s strongly photoaccentuated,” affecting areas exposed to the sun — but it also tends to spare the knuckles on patients’ hands.
 

Used Like an Opioid, But It’s Not Regulated

Kratom is a plant common in southeast Asia and is used as an analgesic. It’s marketed as a “legal opioid” or “legal high” and is sold in 2- or 3-ounce containers of extract or sold as a powder, Dr. Woolery-Lloyd said. The leaves may be boiled into a tea, smoked, chewed, or put into capsules, according to a case report published in February in the Journal of Integrative Dermatology. It is used worldwide and is not regulated in the United States.

“Many of our patients think kratom is a safe, herbal supplement” but often don’t know it can have several side effects and can be addictive, Dr. Woolery-Lloyd said. Its popularity is increasing as reflected by the number of posts related to kratom on social media platforms.

In the February case report, Shaina Patel, BA, and Nathaniel Phelan, MD, from Kansas City University, Kansas City, Missouri, wrote that side effects of kratom include drowsiness, tachycardia, vomiting, respiratory depression, and cardiac arrest, in addition to confusion and hallucinations.

Kratom also has many different effects on the psyche, Dr. Woolery-Lloyd said at the meeting. At low doses, it blocks the reuptake of norepinephrine, serotonin, and dopamine, producing a motivational effect, and at high doses, it creates an analgesic, calming effect. And people who chronically consume high doses of kratom may be susceptible to hyperpigmentation.

Kratom-associated hyperpigmentation should be considered as a diagnosis when evaluating patients for other drug-associated pigmentary disorders, “especially if pigment is photodistributed,” she said. “If you see new-onset hyperpigmentation or onset over several months and it’s very photoaccentuated, definitely ask about use of kratom.”
 

Case Reports Show Patterns of Presentation

A 2022 report from Landon R. Powell, BS, with the department of biology, Whitworth University in Spokane, Washington, and coauthors, published in JAAD Case Reports, noted that kratom use in the United States has increased dramatically. “As measured by call reports to the United States National Poison Data System, in 2011, there were 11 reported kratom exposures, and in the first 7 months of 2018, there were 357 reported exposures,” they wrote.

An estimated 1.7 million Americans aged ≥ 12 years said they had used kratom in the previous year, according to the Substance Abuse and Mental Health Services Administration 2021 National Survey on Drug Use and Health.

In the case report, Mr. Powell and coauthors described a 54-year-old White male patient who had been using kratom for the previous four to five years to reduce opioid use. During this period, he consumed kratom powder mixed with orange juice three to four times a day. He presented with “diffuse hyperpigmented patches on his arms and face in a photodistributed manner, with notable sparing of the knuckles on both hands.”
 

Dark Gray-Blue Skin

In the more recent case report, Ms. Patel and Dr. Phelan described a 30-year-old White male patient who presented with dark gray-blue skin coloring on his cheeks, back of his neck, and the backs of his hands and forearms. He had no other medical conditions and did not take any medications or supplements that cause hyperpigmentation while using kratom.

The patient had been taking kratom for years in the wake of an opioid addiction following medications for a high school injury. He developed an opioid use disorder and tried to replace his pain medications with kratom.

“The patient stopped using kratom in May 2022, but the discoloration remains. It has not regressed in the following 16 months after discontinuing kratom use,” the authors wrote, noting that “whether or not the hyperpigmentation is able to regress is unknown.”

Dr. Woolery-Lloyd is a consultant for AbbVie, Incyte, Johnson & Johnson Consumer, LivDerm, and L’Oreal; a speaker for Eli Lilly, Incyte, L’Oreal, and Ortho Dermatologics; and a researcher/investigator for AbbVie, Allergan, Eirion Therapeutics, Galderma, Pfizer, Sanofi, and Vyne Therapeutics.
 

According to an information page on kratom on the Food and Drug Administration website, health care professionals and consumers can report adverse reactions associated with kratom to the FDA’s MedWatch program.
