Abstract
Germline gain-of-function (GOF) variants in the signal transducer and activator of transcription 3 (STAT3) gene is an inborn error of immunity presenting with autoimmunity and lymphoproliferation. Symptoms can vary widely, and no effective treatment has been established. This study investigated the efficacy of Janus kinase (JAK) inhibitors (JAKi) in patients with STAT3-GOF. Four patients were enrolled and their clinical symptoms before and after the initiation of treatment with JAKi were described. A cell stimulation assay was performed using Epstein-Barr virus transformed lymphoid cell lines (EBV-LCLs) that were derived from the patients with STAT3-GOF. The patients presented with various symptoms, and these symptoms were mostly improved after the initiation of JAKi treatment. Upon interleukin-6 stimulation, the EBV-LCLs of patients showed enhanced STAT3 phosphorylation compare with those of the EBV-LCLs of healthy controls. In conclusion, four Japanese patients with STAT3-GOF were successfully treated with JAKi. JAKi ameliorated various symptoms and therefore, the use of JAKi could be an effective treatment option for patients with STAT3-GOF.
