摘要:

目的 研究磷酸二酯酶4D(PDE4D)基因启动子的变异与宫腔粘连的相关性。 方法 纳入2022—2023年在深圳市宝安区妇幼保健院进行刮宫流产后发生宫腔粘连113例患者与270例未发生宫腔粘连者,检测PDE4D基因rs7701573和rs997421,运用多元logistic回归分析其与宫腔粘连的关联。 结果 与rs997421 CC相比,rs997421 CT+TT基因型发生宫腔粘连的风险更低(校正OR = 0.635,95%CI:0.408 ~ 0.988);亚组分析显示上述保护性作用对广泛宫腔受累(校正OR = 0.518,95%CI:0.268 ~ 0.999)及纤维性粘连者(牢固而致密,校正OR = 0.596,95%CI:0.371 ~ 0.956)更明显。而rs7701573与疾病间无显著关联。 结论 本研究报道了PDE4D基因rs997421 CT+TT基因型与刮宫流产后宫腔粘连发病风险降低有关,尤其是对纤维粘连和广泛宫腔受累有保护作用,本研究为预防刮宫流产后宫腔粘连提供了新的思路。

Abstract:

Objective To investigate the association between genetic variants in the promoter region of the PDE4D gene and the risk of intrauterine adhesions in patients following curettage abortion. Methods This study conducted genotyping of two polymorphisms, rs7701573 and rs997421, in 113 patients diagnosed with intrauterine adhesions and 270 control subjects from the hospital who underwent curettage abortions between 2022 and 2023. Subsequently, we employed multiple logistic regression models to analyze their association with the risks of intrauterine adhesions. Results Individuals with rs997421 CT+TT genotypes had a lower risk of intrauterine adhesions (adjusted OR = 0.635, 95%CI: 0.408 - 0.988) compared to those with the rs997421 CC genotype. The protective effect was more pronounced in patients with more extensive cavity involvement of adhesions (adjusted OR = 0.518, 95%CI: 0.268 - 0.999) and in those with fibrous (Firm & Dense) adhesions (adjusted OR = 0.596, 95%CI: 0.371 - 0.956). However, the rs7701573 polymorphism did not significantly affect the risk of intrauterine adhesions. To our knowledge, this study is the first to report the association between PDE4D gene polymorphisms and the risk of intrauterine adhesions after curettage abortion. Conclusions This study first indicates that the rs997421 polymorphism with the CT+TT genotype is associated with a reduced, protective risk of intrauterine adhesions, especially in patients with fibrous adhesions and extensive uterine cavity involvement. This provides new perspectives for preventing intrauterine adhesions after curettage abortion.
