Predictors for colectomy in patients with acute severe ulcerative colitis: a systematic review and meta-analysis.

Objectives: Acute severe ulcerative colitis (ASUC) poses challenges to patient management owing to its high surgical rate. This study aimed to identify predictors of colectomy in patients with ASUC.

Design: This is a systematic review and meta-analysis.

Lymphocyte subsets for predicting inflammatory bowel disease progression and treatment response: a systematic review.

Background: Lymphocytes play a key role in the pathogenesis of inflammatory bowel disease (IBD) and are widely explored as promising prognostic indicators. We aimed to outline the existing evidences on the capability of lymphocyte subpopulations to predict disease progression and treatment response in patients with IBD.

Methods: The protocol for this review was registered in PROSPERO (registration ID: CRD 42022364126).
