Abstract

Subtle alterations in coagulation and fibrinolysis have been recently reported in patients with endometriosis supporting a potential hypercoagulable status associated with the disease. This cross-sectional study aimed at evaluating some variables of coagulation status and inflammatory markers in women with endometriosis. A total of 314 women who underwent surgery were considered. The case group (n = 169) included patients with a surgical diagnosis of endometriosis, at any stage of disease. The control group (n = 145) included women with a surgical diagnosis of benign gynecologic pathology. No difference was found for thrombin time, International Normalized Ratio (INR), platelet count, neutrophil count, lymphocyte count, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio (PLR) between women with endometriosis and controls. Conversely, patients with endometriosis had significantly shortened activated partial thromboplastin time (APTT) when compared to controls (1.08 ± 0.06 and 1.12 ± 0.19, respectively; P <.01). In the subgroup analysis, women with ovarian endometriosis had significantly shortened APTT values in comparison to women without this form and women with stage I to II endometriosis had significantly shorter APTT values and higher PLR than those with stage III to IV disease. In multivariate logistic regression analysis, after controlling for potential confounders, a shortened APTT remained associated with the disease. Activated partial thromboplastin time is shorter in women with endometriosis but still in the normal range. The evidence is insufficient to foresee a possible use of APTT as a diagnostic marker and to claim a crucial role of a systemic hypercoagulable state in the origin of the disease. A role of the local coagulation system in the pathogenesis of the disease cannot be excluded.
