Effectiveness and safety of baricitinib in severe alopecia areata: 48-week results
This study assessed the effectiveness and safety of baricitinib, a JAK inhibitor, in 253 Italian adults with severe alopecia areata over 48 weeks. Results showed that 63.2% of patients achieved a SALT score of ≤20, indicating significant hair regrowth, with the mean SALT score decreasing from 93.7 to 26.5. Improvements were also noted in trichoscopic findings and patient-reported quality of life measures, with significant reductions in Skindex-16 and HADS scores. Adverse events occurred in 9.4% of patients. The study confirms baricitinib's effectiveness in promoting hair regrowth and enhancing psychological well-being in severe AA patients.
