Infectious disease among adults with allergic contact dermatitis: a propensity score-matched case–control study.

A study published in the British Journal of Dermatology examined the relationship between allergic contact dermatitis (ACD) and infectious diseases in adults. The study used data from the All of Us Research Program, which includes a diverse cohort of participants. The researchers found that individuals with ACD had a higher prevalence of infectious diseases such as impetigo, scabies, cutaneous herpes simplex virus, cutaneous candidiasis, cutaneous abscess, and verruca vulgaris. The study also noted that higher-income individuals had a higher prevalence of ACD, possibly due to greater healthcare engagement. However, the study had limitations, including potential classification errors and a lack of detailed clinical information. While the results suggest a correlation between ACD and infectious comorbidities, they do not establish a causative link. Further research is needed to understand the chronological and causative aspects of this association. The study was supported by the National Institutes of Health's All of Us Research Program.
