Abstract

Abstract Objectives: The estimation of the association between the polymorphism at position -1607/1608 of the gene promoter encoding matrix metalloproteinase type 1 (MMP-1) and the polymorphism at position -1612/1617 of the gene promoter encoding stromelysin type 1 (MMP-3) and the risk of the occurrence of pelvic organ prolapse (POP) and stress urinary incontinence (SUI). Material and methods: 347 women were included into the analysis. POP study: the study group consisted of patients with clinically significant POP (POP-Q scale: 2, 3, 4). Women with normal pelvic floor statics (POP-Q scale: 0, 1) and not reporting symptoms of urinary incontinence were included into the control group. SUI study: the study group – patients with symptoms of stress urinary incontinence, the control group – continent women with normal pelvic floor statics (POP-Q scale: 0, 1). Samples of DNA were isolated from whole blood. The type of polymorphism was detected by RFLP method. Results: Both, in the POP and the SUI study, we have observed no statistically significant differences in the occurrences of MMP-1 and MMP-3 promoter polymorphisms between the study and the control groups. Also, the presence of the alleles G/GG (MMP-1) or 5A/6A (MMP-3) did not modify the risk of the POP and SUI development. Conclusions: Polymorphism type G/GG of gene promoter encoding MMP-1 and polymorphism type 5A/6A of the gene promoter encoding MMP-3 are not associated with the risk of the development of POP and SUI.
