Efficacy and safety of tanshinone IIA in combination with mesalazine in the treatment of ulcerative colitis: a Systematic review and meta-analysis
Abstract
Abstract Background Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by relapsing inflammation of the colon. Tanshinone IIA, a compound derived from traditional Chinese medicine, has demonstrated anti-inflammatory properties and may enhance treatment outcomes when combined with mesalazine. This study aims to determine the overall response rate of Tanshinone IIA in combination with mesalazine for the treatment of UC. Methods We reviewed articles from the establishment of the databases until April 2023 in the PubMed, Embase, Cochrane Library, CNKI, Wanfang, CQVIP, and CBM databases. They included a randomized controlled trial in which the intervention group was given tanshinone IIA plus mesalazine (T + M), while the comparative group was given only mesalazine (M). We removed duplicates or similar papers; papers with no available full text or incomplete data; animal research; and review and systematic review articles. STATA 15.1 was used to analyze the data. Results The perceived total effectiveness rate of T + M was found to be higher than M and the difference was found to be significant (P = 0.000). Additionally, pooled results show that TNF-α (P = 0.000) and CRP (P = 0.000) levels in the T + M group were all significantly lower than that in the M group. Furthermore, MHC-II expression in the T + M group was minors compared to that of the M group (P = 0.001). However, there was no significant difference in the incidence of adverse events between the T + M and M groups (P = 0.700). Conclusion This meta-analysis demonstrates that combining tanshinone IIA with mesalazine significantly enhances the overall treatment efficacy for ulcerative colitis compared to mesalazine alone. Tanshinone IIA also exhibits anti-inflammatory effects by reducing TNF-α, CRP levels, and MHC-II expression without notably increasing adverse events. Despite some limitations, these findings suggest that tanshinone IIA can be a promising adjunctive therapy for ulcerative colitis. Further large-scale, multi-center studies are needed to confirm these results and establish the long-term safety and effectiveness of this combination therapy.
