This study investigated how GnRH agonist therapy affects tissue inflammation, angiogenesis, and apoptosis in women with ovarian endometriosis, adenomyosis, and uterine myoma, comparing specimens from treated versus untreated patients. Biopsy samples were collected from lesions, myometrium, and corresponding endometrium, and immunohistochemistry was used to quantify CD68-positive macrophages and von Willebrand factor–positive micro-vessels, while apoptosis was assessed by TUNEL and activated caspase-3 expression. In the GnRH agonist–treated group, CD68-positive macrophage infiltration and VWF-positive micro-vessel density were significantly decreased, with marked reductions in inflammatory and angiogenic responses in lesions and myometrium, while apoptotic indices and activated caspase-3 Q-H scores increased in eutopic endometrium, lesions, and myometrium. The paper’s main limitation is that it reflects tissue-level changes measured at surgery after variable 3–6 month treatment periods rather than linking these biomarkers to long-term clinical outcomes. This paper is centrally about endometriosis and adenomyosis—its primary focus is how GnRH agonist therapy modulates inflammation, angiogenesis, and apoptosis in tissues from women with these conditions.

Abstract

BACKGROUND: Information is limited regarding the multifunctional role of GnRH agonist (GnRHa) therapy in reproductive diseases. We investigated the pattern of changes in inflammatory reaction, micro-vessel density and apoptosis in the tissues collected from women with endometriosis, adenomyosis and uterine myoma who were treated with or without GnRHa therapy. METHODS: Biopsy specimens were collected from lesions, myometria and corresponding endometria of 45 women with ovarian endometrioma, 35 women with adenomyosis and 56 women with uterine myoma. A fraction of these women were treated with GnRHa therapy for a variable period of 3-6 months before surgery. We performed immunohistochemical analysis of CD68, a macrophage (Mvarphi) marker and von Willebrand factor (VWF), a vessel marker, using respective antibodies. Changes in apoptosis were examined using TdT-mediated dUTP-biotin nick end-labeling assay and by the immunoexpression of activated caspase-3 in tissues after GnRHa therapy. RESULTS: The infiltration of CD68-positive Mvarphi and VWF-positive micro-vessel density were significantly decreased in the endometria of women with endometriosis, adenomyosis and uterine myoma in the GnRHa-treated group when compared with that in the non-treated group. Marked decreases in inflammatory and angiogenic responses were observed in lesions and myometria of these diseases. When compared with the non-treated group, a significant increase in apoptotic index (apoptotic cells per 10 mm(2) area) and quantitative-histogram scores of activated caspase-3 after GnRHa therapy were observed in the eutopic endometria, lesions and myometria of these diseases. CONCLUSIONS: GnRHa was able to markedly reduce the inflammatory reaction and angiogenesis and to significantly induce apoptosis in tissues derived from women with endometriosis, adenomyosis and uterine myoma. These multiple biological effects at the tissue level may be involved in the regression of these reproductive diseases.
