Overview

The goal of this clinical trial is to evaluate the effect of supplementing Bacillus subtilis compared to the control group on the efficacy of Infliximab in patients with Crohn's disease, and to summarize the role of supplementing Bacillus subtilis in the treatment of CD patients.

Participants will be randomized into two groups: the Bacillus subtilis supplementation group and the control group. The patients in the Bacillus subtilis supplementation group received oral Bacillus subtilis capsules for 12 weeks. The control group did not receive additional intervention. Follow up once a week, and after the study, patients will come to the hospital to finish the evaluation indicators.

Description

The goal of this clinical trial is to evaluate the effect of supplementing Bacillus subtilis compared to the control group on the efficacy of Infliximab in patients with Crohn's disease, and to summarize the role of supplementing Bacillus subtilis in the treatment of CD patients.

Participants will be randomized into two groups: the Bacillus subtilis supplementation group and the control group. Patients in the Bacillus subtilis supplementation group take oral Bacillus subtilis capsules once a day, one capsule per time, for 12 weeks, each containing 3×10⁹ CFU of Bacillus subtilis. The control group did not receive additional intervention. Follow up once a week, and after the study, patients will come to the hospital to finish the evaluation indicators.
