A Single Center Experience With Long-Term Ustekinumab Use and Reinduction in Patients With Refractory Crohn Disease

Background: Ustekinumab was approved for moderate and severe Crohn's disease (CD) in 2016, but little is known about long-term outcomes. Methods: A retrospective study evaluated all patients with CD treated with ustekinumab, including patients with reinduction. C-reactive protein (CRP), Harvey-Bradshaw Index (HBI), Short Inflammatory Bowel Disease (SIBDQ), and endoscopy outcomes were collected prospectively. Results: Ninety-six patients received ustekinumab, resulting in improvement in CRP, HBI, and SIBDQ scores with 68% endoscopic improvement/remission. Thirty-four patients underwent reinduction, resulting in improved HBI and CRP. Conclusions: Ustekinumab in refractory CD results in significant clinical and endoscopic improvement and reinduction may be a viable option to recapture response.
