Abstract
Background/aims: Ustekinumab (UST) and infliximab (IFX) are both effective in the treatment of perianal fistulizing Crohn's disease (CD), but limited research has focused on comparing the efficacy of UST versus IFX in this field. This study aimed to compare the effectiveness of UST or IFX in treating perianal fistula of CD patients naive to biological agents in a real-world setting.
Methods: A retrospective cohort study included patients with perianal fistulizing CD treated with UST or IFX was conducted to evaluate the rates of luminal and perianal fistula response and remission at 6 months after treatment.
Results: Ninety-seven patients (49 UST and 48 IFX) were enrolled. Compared to IFX, UST exhibited significantly higher rates of treatment success (89.8% vs. 50.0%, P< 0.001) and intestinal clinical response (85.7% vs. 68.8%, P= 0.048), but no significant differences in fistula remission, fistula response, fistula closure, intestinal clinical remission, endoscopic remission and endoscopic response was observed. Furthermore, multivariate analyses demonstrated complexity of fistula was conversely associated with fistula remission between the UST and IFX groups. Finally, the rates of disease relapse and operation in the IFX group were higher as compared to the UST group during follow-up.
Conclusions: UST may serve as a promising alternative to IFX for the treatment of perianal fistulizing CD.
期刊介绍：
Intestinal Research (Intest Res) is the joint official publication of the Asian Organization for Crohn''s and Colitis (AOCC), Chinese Society of IBD (CSIBD), Japanese Society for IBD (JSIBD), Korean Association for the Study of Intestinal Diseases (KASID), Taiwan Society of IBD (TSIBD) and Colitis Crohn''s Foundation (India) (CCF, india). The aim of the Journal is to provide broad and in-depth analysis of intestinal diseases, especially inflammatory bowel disease, which shows increasing tendency and significance. As a Journal specialized in clinical and translational research in gastroenterology, it encompasses multiple aspects of diseases originated from the small and large intestines. The Journal also seeks to propagate and exchange useful innovations, both in ideas and in practice, within the research community. As a mode of scholarly communication, it encourages scientific investigation through the rigorous peer-review system and constitutes a qualified and continual platform for sharing studies of researchers and practitioners. Specifically, the Journal presents up-to-date coverage of medical researches on the physiology, epidemiology, pathophysiology, clinical presentations, and therapeutic interventions of the intestinal diseases. General topics of interest include inflammatory bowel disease, colon and small intestine cancer or polyp, endoscopy, irritable bowel syndrome and other motility disorders, infectious enterocolitis, intestinal tuberculosis, and so forth. The Journal publishes diverse types of academic materials such as editorials, clinical and basic reviews, original articles, case reports, letters to the editor, brief communications, perspective, statement or commentary, and images that are useful to clinicians and researchers.
