Abstract

BACKGROUND: Calcineurin inhibitors (CNIs) such as cyclosporine and tacrolimus have been shown to be effective for treatment of patients with steroid-dependent or steroid-refractory ulcerative colitis (UC) with moderate to severe activity. However, it has not been determined whether readministration of CNIs is effective in patients who experience relapse after remission induced by CNIs. OBJECTIVE: To determine the effect of readministration of CNIs in patients who had initially responded to CNIs. METHODS: A review of the medical records of 46 patients with moderate to severe UC who were treated with a CNI at a single tertiary teaching hospital with 840 beds was conducted. Remission was defined as a clinical activity index (CAI) score of 3 or less within 2 months of starting CNI therapy. Response was defined as a CAI score of 4 or higher but had decreased by half from the start of CNI therapy. Relapse was defined as flare-up of symptoms that required an additional treatment or colectomy. RESULTS: Of the 46 patients, 37 (80%) achieved clinical remission or response with the initial CNI treatment. Among those 37 patients, 19 experienced relapse (median duration to relapse, 6.4 months), 12 of whom were readministered a CNI. Of the 12 patients, 2 achieved clinical remission, 2 had a response, and the remaining 8 had no response to the CNI. In addition, all patients who responded to CNI readmini-stration experienced relapse within 6 months. CNI readministration was significantly less effective than the initial administration for treatment of UC (80% vs 33%; p = 0.0014). CONCLUSIONS: Readministration of CNIs for relapse after remission with CNI treatment does not seem to be successful. Alternative therapies such as anti-tumor necrosis factor antibody should be used or colectomy should be considered.
