Background/Objectives: Alopecia areata is an autoimmune condition characterized by rapid hair loss in the scalp, eyebrows, and eyelashes, for which treatments are limited. Baricitinib, an oral inhibitor of Janus kinases 1 and 2, has been recently approved to treat alopecia areata. Methods: A total of 23 patients affected by severe alopecia areata (SALT > 50) for more than 6 months were enrolled, including 14 with AU, 3 with AT, and 6 with ophiasis, and all of whom were treated with baricitinib for a minimum of 52 weeks. Clinical and trichoscopic assessments were performed at each visit, and the impact on quality of life, anxiety, and depression was evaluated using the Skindex-16 and the Hospital Anxiety and Depression Scale (HADS), respectively. Results: A total of 23 patients were enrolled, with a mean age of 44.62 years and a mean SALT of 83.66. The mean value of the SALT score decreased to 51.23 at 6 months and 42.41 after one year. Psychological well-being and quality of life also improved, as demonstrated by the decrease in Skindex-16 and HADS scores. Trichoscopic signs showed a decrease in yellow dots and black dots and an increase in vellus hairs and hair regrowth. Adverse events during the treatment period were reported in 18.75% patients. No drop-outs were registered. Conclusions: Data on the effectiveness and safety of baricitinib are promising and support the use of this drug in severe forms of AA, also in the early stages. We also suggest performing trichoscopy in response to therapy.

Background: Urticarial vasculitis (UV) is a rare form of small-vessel vasculitis characterized by persistent urticarial lesions and systemic manifestations. It differs from chronic spontaneous urticaria (CSU) both clinically and pathogenetically, often requiring systemic therapy. Despite its complexity, no standardized treatment algorithm exists. Methods: We conducted a retrospective, monocentric, observational study on 11 patients diagnosed with UV at the Dermatology Unit of Tor Vergata University Hospital (Rome) between 2014 and 2024. Demographic, clinical, serological, and therapeutic data were collected from medical records. The therapeutic response was assessed using the Urticaria Control Test (UCT) score. Results: The cohort comprised predominantly women (91%), with a mean age at diagnosis of 52.8 years. Autoimmune thyroiditis was the most frequent comorbidity (64%). Hypocomplementemia was detected in only one patient (9%), who also had systemic lupus erythematosus. Antihistamines, while usually prescribed, showed limited efficacy since none of the patients achieved complete remission with monotherapy. Systemic corticosteroids demonstrated rapid and effective control in acute phases. Omalizumab produced variable responses, with two patients achieving a high response (HR) and one reaching complete remission (CR). Methotrexate and cyclosporine yielded inconsistent outcomes. Due to the heterogeneity and limited sample size, statistical analyses were not performed. Conclusions: UV presents with diverse clinical profiles and therapeutic responses. No treatment proved universally efficacious, but corticosteroids and omalizumab were effective in an acute and maintenance phase, respectively. Our findings underscore the importance of individualized treatment plans and the need for further studies to define predictive biomarkers and therapeutic strategies in UV.

Background/Objectives: Alopecia areata (AA) and psoriasis are immune-mediated diseases that can coexist, suggesting shared pathogenic mechanisms. While Janus kinase inhibitors (JAKi) are approved for AA treatment, their role in managing concomitant psoriasis and psoriatic arthritis (PsA) remains unclear. This study evaluates the efficacy and safety of baricitinib in patients with severe AA and coexisting psoriasis and/or PsA. Materials and Methods: A retrospective case series of five patients (mean age 53.2 years) with severe AA (SALT > 80) or alopecia universalis (AU) and concomitant psoriasis (n = 2) and/or PsA (n = 3) was conducted in the Dermatology Unit of Policlinico of Tor Vergata, Catholic University of the Sacred Heart and La Sapienza University of Rome, Italy. Patients received baricitinib 4 mg/day and were assessed at weeks 4, 24, and 52 using SALT, PASI, and pVAS scores. Results: At week 52, one patient achieved complete AA remission, while two improved to SALT < 20 (mean SALT 83 to 8.75). Psoriasis remained stable (mean PASI 1.4 to 0.5). However, one PsA patient worsened (pVAS 9) and discontinued the treatment. Conclusions: Baricitinib was effective for AA, with potential benefits for psoriasis, but it may not be optimal for PsA. Further studies are needed to define its role in multiple immune diseases.
