AbstractThis study employs Mendelian randomization (MR) approach to investigate the potential causal association between genetic variants associated with gut microbiota, inflammatory factors, and the risk of uterine fibroids development. We extracted data on 211 types of gut microbiota, 91 inflammatory factors, and uterine fibroids occurrence from genome-wide association studies and applied the inverse-variance weighted (IVW) method for analysis. To further assess the robustness of our MR analysis, we conducted sensitivity tests including Cochrane's Q test, the MR-Egger intercept test, the MR-PRESSO global test, and a leave-one-out analysis. IVW analysis identified a potential causal association between 14 types of gut microbiota and 8 inflammatory factors with the risk of uterine fibroids. When using 91 inflammation-related proteins as the outcome variable, 13 proteins demonstrated a potential causal association with uterine fibroids risk (IVW, all P < .05). Additionally, the MR-Egger intercept and MR-PRESSO global tests indicated no evidence of horizontal pleiotropy (P > .05), and the leave-one-out analysis confirmed the robustness of the results. This MR approach suggests that specific gut microbiota and inflammatory factors may have a causal association with the development of uterine fibroids, shedding light on the pathogenesis of uterine fibroids and potentially identifying targets for future therapeutic interventions.Copyright © 2024 the Author(s).
