The mechanism, efficacy and safety of Tofacitinib on the treatment of juvenile idiopathic arthritis / 中华实用儿科临床杂志

ABSTRACT

Juvenile idiopathic arthritis(JIA) is one of the most common chronic connective tissue diseases characterized by unknown etiologic arthritis with the onset before the age of 16 years and disease course for more than 6 weeks.JIA may be accompanied by impairment of multiple organ function.Recent studies have shown the important role of the Janus kinase (JAK)-signal transducer and activator of transcription (STAT) pathway in the pathogenesis of JIA.Tofacitinib is an oral Janus kinase(JAK) inhibitor approved by Food and Drug Administration (FDA) in 2012 for the effective treatment of rheumatoid arthritis.However, there is little clinical evidence for the use of Tofacitinib in pediatrics.This review aims to clarify the mechanisms, efficacy and safety of Tofacitinib on the treatment of JIA.
