TNF and inflammatory bowel disease: Most patients achieved clinical remission at the end of the study period.[30] Moreover, UC patients who lose responsiveness to anti‐TNF therapy show improvements in symptoms and mucosal inflammation after FMT.[31] In another study of patients with prior failure of infliximab in CD who received FMT as a switch therapy, those who received FMT had significantly lower rates of clinical relapse compared with patients who received IFX treatment.[32] These studies indicate that FMT affects the efficacy of anti‐TNF therapy in IBD patients.
