Successful treatment of Crohn’s disease-related peripheral spondyloarthritis with upadacitinib: two case reports and case-based review.
Case Report
Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn’s disease (CD), not only causes significant intestinal inflammation but also leads to extra-intestinal manifestations such as spondyloarthritis (SpA). Although the efficacy of tumor necrosis factor (TNF) inhibitors has been reported for IBD-related SpA, some cases still encounter treatment failure, highlighting the need for novel therapeutic alternatives. Recently, Janus kinase inhibitors have demonstrated their efficacy in IBD and SpA, yet their impact on CD-related SpA remains unexplored. Here we present the first two cases of CD-related peripheral SpA successfully treated with upadacitinib. Additionally, our literature review identified a reported case of CD-related peripheral SpA treated with tofacitinib. All cases achieved clinical remission of both CD and peripheral SpA with Janus kinase inhibitors, and no adverse events or disease relapses were reported during the observation period. Our cases and literature review highlight the promising potential of Janus kinase inhibitors as a novel treatment not only for intestinal inflammation of CD, but also for CD-related peripheral SpA.
