Superior persistence of ustekinumab compared to anti-TNF in vedolizumab-experienced inflammatory bowel diseases patients: a real-world cohort study.
BMC Gastroenterol
December 2024
Department of Gastroenterology and Hepatology, Linkou Branch, Chang Gung Memorial Hospital, 5, Fu-Hsin Street, Guei-Shan District, Taoyuan, 33305, Taiwan.
Background/aims: The increasing use of biologic therapies for moderate to severe inflammatory bowel disease (IBD) highlights the importance of optimal treatment sequencing, particularly after vedolizumab (VDZ) exposure. Studies comparing the effectiveness of ustekinumab (UST) and antitumor necrosis factor (anti-TNF) agents post-VDZ are limited.
Methods: This retrospective study analyzed VDZ-experienced IBD patients treated with UST or anti-TNF (adalimumab and infliximab) from May 2019 to January 2024.
Microbiome and Mucosal Immunity in the Intestinal Tract.

The human bowel is exposed to numerous biotic and abiotic external noxious agents. Accordingly, the digestive tract is frequently involved in malfunctions within the organism. Together with the commensal intestinal flora, it regulates the immunological balance between inflammatory defense processes and immune tolerance.

Clinically heterogeneous spectrum and molecular phenotypes of inflammatory bowel disease (IBD) remain to be comprehensively elucidated. This exploratory multi-omics study investigated the serum molecular profiles of Crohn's disease (CD) and ulcerative colitis (UC), in association with elevated fecal calprotectin and disease activity states. The serum proteome, metabolome, and lipidome of 75 treated IBD patients were profiled.

Division of Gastroenterology, Department of Medicine, University of Miami - Leonard Miller School of Medicine, Miami, FL, USA.
Background And Aims: The advantages of endoscopic vs histologic assessments of inflammation in inflammatory bowel disease remain unclear. We compared endoscopic and histologic inflammation in a prospective cohort. Furthermore, in patients with discordant findings, we compared the ability of endoscopy vs histology to predict disease course.

Intestinal fibrosis, a severe complication of Crohn's disease (CD), is linked to chronic inflammation, but the precise mechanism by which immune-driven intestinal inflammation leads to fibrosis development is not fully understood. This study investigates the role of myeloid-derived suppressor cells (MDSCs) in intestinal fibrosis in CD patients and a 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced mouse model. Elevated MDSCs are observed in inflamed intestinal tissues prior to fibrosis and their sustained presence in fibrotic tissues of both CD patients and murine models.
