Chiang and colleagues have conducted an exceptionally well-done study looking at the association of salt intake with atopic dermatitis. The study analyzed very large patient groups against a different population to confirm the findings. They identified a "statistically significant" increased likelihood of having atopic dermatitis in people with higher urine sodium excretion. The difference in rate seems to be very small, however. The authors concluded that lower dietary sodium intake may be a cost-effective and low-risk intervention for atopic dermatitis. Given the small effect size that was observed, the possibility that the association wasn't a causal one, and the difficulty of getting patients to change their diets, it seems unlikely to me that sodium restriction would be helpful, though it would be nice if it were.

 

In this real-life study, Patruno and colleagues found that dupilumab worked well but more slowly in patients with a higher body mass index (BMI). On the basis of these findings, if patients are not in a hurry, the standard dose of dupilumab should eventually work, regardless of BMI. If patients are in a hurry to see improvement, perhaps dose escalation could be considered for patients with a high BMI, or perhaps topical triamcinolone could be used to speed time-to–initial resolution in the high-BMI population.

 

In the very well-done study by Silverberg and colleagues, tapinarof was effective, well tolerated, and generally safe for atopic dermatitis in adults and children. Great! Topical tapinarof should soon be another good option for our patients with atopic dermatitis. How valuable will it be? We already have topical corticosteroids that are very effective for atopic dermatitis, and we have multiple other nonsteroidal topical agents, including topical calcineurin inhibitors and topical ruxolitinib. 

Perhaps the biggest limitation of all these treatments is poor adherence to topical treatment. I'm not sure how effective even highly effective nonsteroidal topicals will be for patients who did not respond to topical steroids when the primary reason for topical steroid failure is poor treatment adherence. I'd love to see the development of a once-a-week or once-a-month topical therapy that would address the poor-adherence hurdle.

Abrocitinib is an effective treatment for improving atopic dermatitis. Although atopic dermatitis is a chronic condition requiring long-term management, we'd like to minimize exposure to the drug to avoid side effects. Thyssen and colleagues described the effectiveness of two maintenance treatment regimens: continuing 200 mg/d or reducing the dose to 100 mg/d. Both regimens prevented flares more than did placebo. This study also provided information on safety of the maintenance regimens. Rates of herpetic infections were low across all the groups, but unlike the two treatment groups, there were no cases of herpes simplex infection in the patients in the placebo arm.
