Cyclophilin A expression is significantly higher in ovarian endometrioma cyst walls than in control endometrial tissue and correlates with endometrioma recurrence and dysmenorrhea recurrence.

This cross-sectional study compared cyclophilin A (CyPA) immunoreactivity in cyst wall samples from 44 consecutive women with histologically confirmed ovarian endometrioma to control endometrial tissue from 40 women without endometriosis. CyPA expression in glandular cells, stromal cells, and capillary endothelium was significantly higher in endometrioma cyst walls than in control endometrium. Correlation analyses showed glandular CyPA expression associated with endometrioma recurrence, while stromal and vascular endothelial CyPA expression were associated with dysmenorrhea recurrence. This paper centrally about endometriosis — it evaluates CyPA expression in ovarian endometrioma tissue and links it to recurrence and vascularity.

Abstract

Endometriosis is defined as the presence of functional endometrial tissues outside of the uterine cavity. Ovarian endometrioma is the most common type of endometriosis. It is an estrogen-dependent inflammatory disease that frequently causes infertility and chronic pelvic pain. Cyclophilin A (CyPA) is secreted from various types of cells in response to inflammatory stimuli. Many previous studies have shown that the increased expression and/or heightened plasma levels of CyPA exacerbates inflammation. The aim of this study is to evaluate CyPA immunoreactivity in ovarian endometrioma cyst wall. In this cross-sectional study, CyPA immunoreactivity in endometrial tissue samples obtained from uterine cavity and in endometrioma cyst walls of 44 consecutive women with ovarian endometrioma were compared with control endometrial tissue samples obtained from uterine cavity of 40 women without endometrioma. All endometrioma samples were confirmed via histopathological examination. Finally, the relationship between CyPA immunoreactivity and the clinicopathological findings related to endometrioma were evaluated. The CyPA expression rates in glandular cells, stromal cells, and the capillary endothelium were significantly higher in endometrioma cyst walls of women with ovarian endometrioma than in the control endometrial tissue of women without endometrioma (p = 0.0002, p = 0.0417 and p = 0.0067, respectively). The correlation analysis demonstrated that glandular CyPA expression was correlated with endometrioma recurrence (p = 0.0267). However, stromal and vascular endothelial CyPA expression were correlated with dysmenorrhea recurrence (p = 0.0023 and p = 0.0003, respectively). In conclusion, the increased expression of CyPA in ectopic endometrial tissue is associated with endometrioma recurrences and vascularity.
