ARTICLE HIGHLIGHTS
Research background

There are cases of refractory ulcerative colitis in which tacrolimus does not induce remission.

Research motivation

A biomarker capable of predicting the induction effect of tacrolimus is desired.

Research objectives

The usefulness of serum albumin as a predictor of the therapeutic effect of oral tacrolimus for ulcerative colitis was investigated.

Research methods

Patients treated with tacrolimus at our hospital were divided into a remission group and a failure group, and data including serum albumin at the start of observation and at the first and second weeks were retrospectively examined.

Research results

Lower albumin levels in week 2 than in week 0 after achieving trough levels of tacrolimus were shown to increase risk for failure, including colectomy and switch to biologics, within 3 mo.

Research conclusions

Early serum albumin changes in patients with ulcerative colitis treated with tacrolimus predict clinical outcome.

Research perspectives

In cases where albumin levels in week 2 are lower than week 0, changes to other treatment options, including surgical total colectomy, should be considered as soon as possible.
