This study aimed to analyze the correlation between the immunoexpression of matrix metalloproteinase 9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TiMP1) in the uterosacral ligaments in patients with uterine prolapse.
This analytic-correlative cross-sectional study included 32 patients who were admitted at the Hasan Sadikin General Hospital from July to December 2013. Sixteen of the patients had uterine prolapse, while the rest did not. The patients underwent total hysterectomy, radical hysterectomy, or staging laparotomy. MMP-9 and TiMP1 expression in the uterosacral ligaments was measured via immunohistochemical staining. The median expression per field of view was calculated using a histoscore.
MMP-9 expression in patients with uterine prolapse was found to be higher than that in the control group. Meanwhile, TiMP1 expression showed no significant difference between the groups. Spearman's analysis showed a moderate correlation between the expression of MMP-9 and uterine prolapse incidence (P=0.02), with a correlation coefficient of 0.574.
There is a moderate correlation between MMP-9 expression and the incidence of uterine prolapse. It can be considered one of the primary etiologies of uterine prolapse.
本研究旨在分析子宫脱垂患者子宫骶韧带中基质金属蛋白酶9(MMP-9)和金属蛋白酶组织抑制剂-1(TiMP1)的免疫表达之间的相关性。
这项分析相关性横断面研究纳入了2013年7月至12月在哈桑·萨迪金综合医院收治的32例患者。其中16例患者患有子宫脱垂,其余患者未患此病。患者接受了全子宫切除术、根治性子宫切除术或分期剖腹手术。通过免疫组织化学染色测量子宫骶韧带中MMP-9和TiMP1的表达。使用组织评分计算每个视野的中位表达。
发现子宫脱垂患者中MMP-9的表达高于对照组。同时,两组之间TiMP1的表达无显著差异。Spearman分析显示MMP-9的表达与子宫脱垂发生率之间存在中度相关性(P=0.02),相关系数为0.574。
MMP-9的表达与子宫脱垂的发生率之间存在中度相关性。它可被视为子宫脱垂的主要病因之一。
