October 24, 2024 updated by: Hongmei Song, Peking Union Medical College Hospital

Efficacy and Safety of Tofacitinib in Patients with Refractory Blau Syndrome: a Prospective Cohort Study

This is a prospective cohort study to observe the efficacy and safety of Tofacitinib in children with Blau syndrome (BS). The investigators would analyze the rate of remission or low disease activity after treatment as well as changes in inflammatory markers, patients' and physician's global assessment of disease activity to determine the efficacy and safety of Tofacitinib.
