Evaluation of Soluble CD90: Potential for Diagnostic Significance in Endometriosis Patients

Background. Endometriosis is a chronic and debilitating gynecologic disorder, driven by endocrine and immune dysfunctions, which lead to poor endometrial differentiation and attenuated fertility. Escape from immune surveillance and involvement of inflammatory mechanisms appear to be factors in disease progression. Current diagnostic guidelines for endometriosis still lack an efficient biomarker. Here, we report a study on two previously unexplored factors as potential biomarkers for endometriosis. Methods. A case-control study was performed to evaluate the diagnostic potential of serum CD90 and CD83 levels in endometriosis patients (cases validated by surgical and histological examination) compared to healthy controls. Serum was collected from age-matched females and analyzed by ELISA. Results. Comparison of endometriosis patients to the control group showed significantly elevated levels of serum CD90 (1160±856 pg/mL vs. 334±228 pg/mL; ∗∗∗∗p
