MONDAY, Aug. 10, 2026 (HealthDay News) -- Individuals with atopic dermatitis have an increased risk for herpes zoster, according to a study published online Aug. 5 in JDDG: Journal der Deutschen Dermatologischen Gesellschaft.Anna K. Schober, from the London School of Hygiene and Tropical Medicine, and colleagues conducted a matched cohort study using primary care data from the U.K. Clinical Practice Research Datalink Aurum database (1997 to 2023) to examine the association between atopic dermatitis and herpes zoster.The researchers found that individuals with atopic dermatitis had an increased risk for herpes zoster (adjusted hazard ratio, 1.28). Minimal reductions in the association were seen with adjustments for different definitions of oral corticosteroid exposure as well as other traditional immunosuppressants. There was an increase seen in the risk for herpes zoster with increasing atopic dermatitis severity (adjusted hazard ratios, 1.22, 1.28, and 2.33 for mild, moderate, and severe atopic dermatitis, respectively)."With emerging treatment options and broader implementation of herpes zoster vaccination programs, incorporation of the evidence from this study into clinical practice and vaccination guidelines could improve the standard of care for patients with atopic dermatitis and help prevent herpes zoster," the authors write.Abstract/Full Text.Sign up for our weekly HealthDay newsletter
