Takayasu arteritis (TAK) is a form of large vessel vasculitis resulting in thickening and stenosis of the large-sized arteries, particularly the aorta and its main branches. Ulcerative colitis (UC) is a major complication of TAK, sharing some genetic background and pathogenesis.1 Serum levels of pro-inflammatory cytokines, such as interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-α), are potential biomarkers to reflect disease activity of TAK. Thus, IL-6 or TNF-α inhibitors have been used for treating refractory TAK. A randomised controlled trial suggested clinical efficacy and safety of tocilizumab in patients with refractory TAK, although the trial failed to achieve its primary endpoint.2 We here present a patient in whom tofacitinib (TOF), a Janus kinase (JAK) inhibitor, successfully induced a remission of TAK and UC resistant to both TNF-α and IL-6 inhibitors.

A 32-year-old Japanese female with a medical history of TAK and UC visited our hospital complaining of chest pain, abdominal …
