Context:
Evidence regarding curcumin supplementation in patients with ulcerative colitis (UC) has been inconsistent.
Objective:
This umbrella review aimed to summarize the effects of curcumin supplementation on UC and assess the strength of the evidence.
Data Sources:
A systematic search was conducted across the Cochrane Database of Systematic Reviews, PubMed, Web of Science, EMBASE, CNKI, Sino-Med, VIP, and Wanfang databases from their inception to June 9, 2024.
Data Extraction:
Two review authors independently extracted data.
Data Analysis:
Methodological quality assessment, and evidence quality assessment, based on predetermined criteria, were performed by 2 independent reviewers. Seven systematic reviews and meta-analyses, encompassing 18 outcomes related to curcumin on UC, were included. Of these, 11 (77.78%) demonstrated statistical significance at the nominal level (P < .05).
Conclusion:
None of the reported outcomes were supported by high-certainty evidence, making the therapeutic potential of curcumin uncertain. Nevertheless, despite the widespread methodological shortcomings of the SRs/MAs, our study highlights opportunities to strengthen future research efforts.
Umbrella Review Registration:
PROSPERO registration No. CRD42024564400.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
