Ulcerative colitis is a chronic debilitating disease characterized by relapsing in intestinal inflammation and ulcers with no available cure. This is a clinical case report of a 52-year-old female patient with 30 years history of left-sided chronic ulcerative colitis controlled with standard of care (mesalamine and azathioprine) which subsequently relapsed and developed into active refractory ulcerative colitis. The patient became unresponsive to her medications including different forms of mesalamines and did not respond favorably to any of the other current therapies. Numerous attempts to stabilize her condition with immunosuppressants, steroids, probiotics, antibiotics, mesalamines, and various biologic agents failed to improve her clinical symptoms, and the patient was being considered for colectomy. As the last resort, modified therapy was prescribed with ustekinumab, a non-selective, anti-IL12/23 p40 monoclonal antibody. This medication has not been yet approved for use in ulcerative colitis patients. In this clinical case we report the efficacy of ustekinumab to rapidly induce and maintain remission of the severe chronic ulcerative colitis in the patient. To the best of our knowledge, this is the first report of utilizing ustakinamub therapy for rapid induction in an active refractory ulcerative colitis patient resulting in complete remission for over one year.
