Atopic dermatitis (AD) is sometimes accompanied by alopecia areata (AA) or, in severe cases, alopecia universalis (AU). Preclinical studies have shown that type 1 and type 2 cytokines are involved in AD and AA.1,2 Janus kinase (JAK) inhibitors are effective blockers of JAK/signal transducer and activator of transcription-mediated inflammatory signaling pathways, which regulate multiple cytokines, such as interleukins and interferons.3 A recent case report showed hair regrowth after simultaneous treatment of AU and AD with tofacitinib, a selective inhibitor of JAK 1 and JAK 3.
