Abstract

INTRODUCTION AND HYPOTHESIS: Changes in the expression of type III collagen have been linked to women's predisposition to pelvic organ prolapse (POP); however, the findings of prior studies have been conflicting. This study was aimed at investigating whether changes in the type III collagen gene expression levels occur in POP development. METHODS: A systematic review and meta-analysis were conducted on research articles that evaluated type III collagen gene expression levels in patients with POP compared with those without the condition. The articles, published between January 2000 and February 2024, were obtained from PubMed, ScienceDirect, Semantic Scholar, and EBSCO databases. Data were analyzed using fixed-effect models, and the pooled standardized mean difference (SMD) was calculated. Cochrane's Review Manager 5.4 was used for the analysis. The aggregated SMD with 95% confidence interval (CI) regarding type III collagen gene expression levels relative to POP development was the main outcome measure. Results with p < 0.05 were considered statistically significant. RESULTS: Six studies were included in our analysis, comprising 229 POP cases and 139 non-POP cases. Our meta-analysis indicated that patients with POP had higher type III collagen gene expression levels than those without POP (SMD = 0.32; 95% CI: 0.07 to 0.56; p = 0.01). CONCLUSION: The results of this study provide evidence that a higher type III collagen gene expression levels is significantly associated with POP.

Key Findings

Six studies were included in our analysis, comprising 229 POP cases and 139 non-POP cases. Our meta-analysis indicated that patients with POP had higher type III collagen gene expression levels than those without POP (SMD = 0.32; 95% CI: 0.07 to 0.56; p = 0.01).
