Women with endometriosis have increased levels of placental growth factor in the peritoneal fluid compared with women with cystadenomas.

چکیده
BACKGROUND To assess the release of placental growth factor (PlGF) into peritoneal fluid in women with and without endometriosis, we measured its concentration with reference to disease stage, the presence of red endometriotic lesions and the phase of menstrual cycle. METHODS Surgery was scheduled in the proliferative or secretory phase of the menstrual cycle for 59 women with (n = 35) or without (n = 24) endometriosis. The latter group comprised women undergoing surgery for ovarian cystadenomas. PlGF concentrations in the peritoneal fluid were measured using an enzyme-linked immunosorbent assay. RESULTS PlGF concentration in the peritoneal fluid was markedly elevated in the endometriosis patients (median 189 pg/ml, interquartile range 84-475 pg/ml) as compared with the controls (88 pg/ml, 41-213 pg/ml; P < 0.001), especially in women with red lesions. Significantly greater values during the secretory phase of the menstrual cycle as compared with the proliferative phase were observed in both the control (cystadenoma) group (P < 0.05) and the endometriosis group (P < 0.001). CONCLUSIONS Our findings suggest that production of PlGF is sensitive to the cyclic changes in ovarian steroids and may contribute to the pathogenesis of endometriosis, especially that of red lesions, by promoting neovascularization.

Background: Endometriosis is known as one of the most common disease in women of reproductive age. Due to importance role of vascular endothelial growth factor (VEGF) in neo-vascularization for the implantation of endometrial cell and different reported results for VEGF level in the serum and peritoneal fluid (PF) in endometriosis patients, this study was designed to determine the serum and PF ...

The Correlation between Serum and Peritoneal Fluid CA125 Level in Women with Pelvic Endometriosis
Background Despite a high prevalence of endometriosis, there still exist many challenges in diagnosing the disease. This study aims to evaluate non-invasive and practical diagnostic methods by measuring serum and peritoneal fluid CA 125 levels in patients with endometriosis. A secondary aim is to determine the correlation between these markers with the stage of disease as well as the relationsh...

SUMMARY Infertility has a special importance in gynecology in causing social, psychological and somatic prohlems. Endometriosis is a benign but progressive disorder in reproductive life and is more common in infertile women. CA 125 is a cell membrane glycoprotein. The endometrium is one the known source of this antigen and seems to be elevated in the pelvic endometriosis. In this study, from...
