Predictive Factors for Efficacy of Oral Tacrolimus Induction Therapy in Moderate to Severe Ulcerative Colitis Patients: Large Multicenter Retrospective Cohort Study.

BACKGROUND

Tacrolimus (TAC), a calcineurin inhibitor, is used for remission induction therapy in patients with moderate to severe ulcerative colitis (UC), with short-term efficacy and related predictive factors shown in previous cohort studies. However, most studies reported data for only a limited number of patients enrolled from a single center. We performed a large multicenter retrospective cohort study to identify factors related to prediction of clinical remission in UC patients treated with oral TAC.

METHODS

The medical records of patients with moderate to severe UC treated with oral TAC as induction therapy at 7 institutions between April 2009 and March 2017 were retrospectively reviewed.

RESULTS

A total of 216 patients who received TAC for induction were analyzed, of whom 123 (56.9%) showed clinical remission at week 12. Logistic regression analysis indicated that previous or current use of antitumor necrosis factor (TNF)-α antibodies (odds ratio [OR], 0.259; P = .006), and concomitant treatment with 5-aminosalicylate (5-ASA) at the baseline (OR, 0.268; P = .005) were independent predictive factors correlated with failure of clinical remission, whereas higher levels of C-reactive protein (OR, 1.124; P = .014) predicted achievement of clinical remission.

CONCLUSIONS

Results of this multicenter study clearly indicate the efficacy of TAC induction therapy for patients with moderate to severe UC. Notably, previous or current use of anti-TNF-α antibodies was associated with poor achievement of clinical remission by week 12.
