Abstrakt:	Background and aim Tacrolimus (tac) is used for induction therapy in refractory and severe ulcerative colitis (UC) cases. The aim of this study was to identify the factors contributing to the induction of remission and to assess the endoscopic or histologic improvement rates following induction of remission by tac. Methods This study examined data from 67 UC patients treated with tac for induction of remission out of 515 patients attending Dokkyo Medical University Hospital. The primary endpoint of the study was the analysis of factors contributing to successful induction of remission treatment with tac. The secondary endpoints were the corticosteroid-free remission rate at 52 weeks after tac induction and the endoscopic and histologic improvement rates following induction of remission. Results Analysis of factors contributing to successful induction of remission by tac showed the Lichtiger index at the beginning of remission induction therapy was 9.5 ± 2.5 for the successful remission group and 11.5 ± 2.4 for the unsuccessful remission group (p = 0.002). The proportions of patients who had used immunomodulators were 13/45 (28.9%) for the successful remission group and 14/22 (63.6%) for the unsuccessful remission group (p = 0.006). The proportions of patients who had used anti-tumor necrosis factor (TNF)α biologics were 4/45 (8.9%) for the successful remission group and 8/22 (36.4%) for the unsuccessful remission group (p = 0.006). Conclusion Patients with UC who are potential candidates for intensification of remission maintenance therapy are good candidates for induction of remission with tac. Moreover, improvement in endoscopic inflammation might be a predictive marker of response to remission induction therapy with tac.
