Janus kinase inhibition in induction treatment of anti‐MDA5 juvenile dermatomyositis‐associated rapidly progressive interstitial lung disease

Abstract

Tofacitinib has an important role in pediatric rapidly progressive interstitial lung disease (ILD) associated with juvenile dermatomyositis (JDM), an otherwise potentially fatal condition. It may be useful in induction of remission and can be used safely to maintain remission. Serum ferritin and interleukin-18 are useful markers for tracking activity and response of JDM-associated ILD.
