Dual Relief: How Atopic Dermatitis Treatments Affect Alopecia Areata-A Small Retrospective Cohort Study.

Atopic dermatitis (AD) and alopecia areata (AA) frequently coexist due to shared immune-mediated mechanisms. Treatments targeting AD, including Janus kinase (JAK) inhibitors and dupilumab, may impact AA outcomes in unpredictable ways. This study aims to evaluate the effects of advanced therapies on patients with concurrent AD and AA to inform treatment strategies. A retrospective cohort study was conducted on six patients diagnosed with both AD and AA. Treatments included systemic corticosteroids, dupilumab, and JAK inhibitors (baricitinib and upadacitinib). Outcomes were assessed at six months using the Severity of Alopecia Tool (SALT), Dermatology Life Quality Index (DLQI), and Scoring Atopic Dermatitis (SCORAD) scores. Patients receiving JAK inhibitors showed significant improvements in AD and AA outcomes, with mean reductions of 95.65% in SALT scores, 91.03% in DLQI scores, and 89.57% in SCORAD scores. Dupilumab was associated with the onset or worsening of AA in two patients. Systemic corticosteroids provided short-term benefits but are unsuitable for long-term management due to safety concerns. JAK inhibitors are effective for managing concurrent AD and AA, offering substantial improvements in disease control and quality of life. However, dupilumab requires cautious use in patients with these comorbid conditions. Personalized treatment strategies, informed by patient-specific factors, are essential for optimizing outcomes and minimizing risks. Further research is needed to identify predictive markers and refine therapeutic approaches for this challenging population.
