Beneficial Effect of Upadacitinib in an Adult Patient with Juvenile Idiopathic Arthritis-associated Uveitis after Unsatisfactory Response to Tofacitinib: A Case Report

Objective Several case reports have been published on the effect of janus kinase inhibitors (JAK-I) on juvenile idiopathic arthritis-associated uveitis (JIAU). Both tofacitinib and baricitinib have been described as therapeutically effective in JIAU.Methods We here present a case of a 24-years-old female with refractory course of JIAU receiving upadacitinib therapy.Results After failing multiple conventional and biologic disease-modifying antirheumatic drugs, the patient finally achieved clinical remission on upadacitinib monotherapy, despite a previously unsatisfactory clinical response of both arthritis and uveitis to tofacitinib monotherapy.Conclusion This case suggests that switching JAK-I might be a successful strategy in the treatment of JIAU, despite previously incomplete response to other preparations.
