Clinical Experience with Oral Tofacitinib in a Patient with Alopecia Areata Universalis and Rheumatoid Arthritis.

Alopecia areata (AA) is a chronic and autoimmune disease frequently characterized by a challenge management between dermatologists. At present, JAK-inhibitors have demonstrated encouraging results in AA treatment. Therefore, this study reports a case of alopecia universalis in a patient with rheumatoid arthritis (RA), whose methotrexate therapy shown unsatisfactory response in RA control. After the introduction of 10 mg (oral route) per day of tofacitinib, a JAK-inhibitor, an improvement of almost 50% in severity alopecia tool score occurred with maintained response even after 3 months of medication suspension. From this time, we corroborate the effectiveness of JAK-inhibitors presented in the scientific literature. In addition, we inquiry the real impact of methotrexate on JAK-start signaling inhibition in AA pathophysiology.
