Abstract
OBJECTIVE: Sarcoidosis is an idiopathic inflammatory disorder that is difficult to treat. There is accumulating evidence that constitutive activation of Janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling occurs in sarcoidosis and represents a target for treatment. Here we report the efficacy of tofacitinib, a Janus kinase (JAK) inhibitor, in a single patient with multiorgan sarcoidosis. METHODS: A patient with long-standing multiorgan sarcoidosis who was unresponsive to other commonly used therapies, including methotrexate, prednisone, and tumor necrosis factor α blockade, was treated with tofacitinib. RESULTS: Tofacitinib treatment resulted in clinical remission of cutaneous sarcoidosis lesions and resolution of positron emission tomography avid lesions in internal organs after 6 months. An evaluation of lesional tissue and blood before and during treatment showed resolution of granulomatous inflammation and normalization of disease biomarkers. CONCLUSION: This case illustrates the promise of JAK inhibition as a strategy to treat recalcitrant sarcoidosis and suggests that further study of JAK inhibitors in sarcoidosis is needed.
