In vitro study of prolactin secretion by ectopic endometrial stromal cells]

OBJECTIVE: To investigate the relationship between prolactin (PRL) secretion by ectopic endometrial stromal cells and elevated PRL concentrations of peritoneal fluid in patients with endometriosis. METHODS: Twelve samples of each ectopic endometrium and normal endometrium were separated and cultured in vitro. After stimulated with progesterone(10(-8) mol/L) for 6 days, PRL levels in the media of cultured stromal cells from both tissue types were measured by enzyme-labeled immunosorbent assay(ELISA). A study of correlation between PRL level in culture supernatant of stromal cells from ectopic endometrium and American Fertility Society (AFS) classification of endometriosis score was performed. The expression of PRL protein of stromal cells from both tissue types were determined by immunocytochemical method. RESULTS: PRL was secreted in similar concentrations by stromal cells from both tissue types. The mean levels of PRL in ectopic and normal endometria were (21.8 +/- 8.0) and (24.5 +/- 7.9) micrograms.L-1.6 d-1 per, respectively (P > 0.05). There is significant positive correlation between PRL secretion by ectopic endometrial stromal cells and the scoring of endometriosis (P < 0.05). There were no significant difference in the immunostaining integral score of PRL between the two groups. CONCLUSION: Production of PRL by ectopic implants of endometriosis is likely to be a contributing factor of the elevated peritoneal fluid PRL in patients with endometriosis.     

Cytokine profiles in serum and peritoneal fluid from infertile women with and without endometriosis

OBJECTIVE: To study the serum and peritoneal fluid cytokine profiles in infertile women with minimal/mild active endometriosis. METHODS: Fifty-seven consecutive infertile women undergoing laparoscopy for unexplained infertility had peritoneal fluid and serum samples obtained at the time of laparoscopy. The levels of interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-1 beta (IL-1 beta), vascular endothelial growth factor (VEGF), tumor necrosis factor-alpha (TNF-alpha), monocyte chemotatic protein-1 (MCP-1), RANTES, platelet derived growth factor (PDGF), soluble Fas (sFas), and soluble Fas Ligand (sFasL) in peritoneal fluid and serum were measured to compare the concentration in both biological fluids, in women who have minimal/mild red endometriosis using women with no endometriosis as controls. RESULTS: Peritoneal fluid levels of MCP-1, IL-8 and IL-6 were significantly higher in the endometriosis group (P < 0.012, P = 0.003, and P = 0.015, respectively). There was no significant difference in the peritoneal fluid levels of IL-1 beta, TNF-alpha, RANTES, VEGF, PDGF, sFas and sFasL in the two groups. Although serum levels of IL-8 were higher in women with endometriosis, the difference was not significant (P = 0.07). Serum levels of PDGF, IL-6, RANTES, IL-1 beta, TNF-alpha, and sFas, were not significantly different in the two groups. CONCLUSION: The elevated levels of MCP-1, IL-6, and IL-8 in peritoneal fluid but not serum may indicate the importance of local macrophage activating factors in the pathogenesis of endometriosis.     

子宫内膜异位症患者腹腔液白细胞介素6,8及转化生长因子β1 …

OBJECTIVE: To investigate the role of cytokines in peritoneal fluid on pathogenesis of endometriosis (EM). METHODS: Interleukin-6 (IL-6), interleukin-8(IL-8) and transforming growth factor-beta 1 (TGF-beta 1) contents in peritoneal fluid (PF) of 31 cases with EM were detected by enzyme linked immunoabsorbent assay (ELISA) and compared with the counterparts of 22 cases without EM (controls). The correlation analyses between cytokine concentrations in peritoneal fluid of EM patients and the severity of EM or dysmenorrhea score were performed. RESULTS: The peritoneal fluid from patients with EM contained significantly greater amounts of IL-6 [(1.8 +/- 0.4) ng/L] and IL-8 [(1.7 +/- 0.5) ng/L] than those in controls [(1.2 +/- 0.2) ng/L and (1.4 +/- 0.3) ng/L respectively, P < 0.05]. However, in the amounts of TGF-beta 1 there were no significant difference (P > 0.05) between the two groups. The highest PF IL-6 and IL-8 concentrations were found in stage II, III and stag I, II EM respectively. A significant correlation between PF IL-6 content and the severity of disease was noted but there were no evidences of a relationship between concentrations of IL-8 and TGF-beta 1 and the severity of EM as well as between concentrations of three cytokines and dysmenorrhea score. CONCLUSION: Unusual levels of IL-6 and IL-8 in PF of EM patients partly account for imbalance of the immunologically dynamic environment in peritoneal cavity of EM patients.     

Serum and peritoneal fluid proteins in women with and without endometriosis

We examined the proteins in serum and peritoneal fluid of women with endometriosis (and of healthy controls) for evidence of an autoimmune response that might account for their impaired fertility. No antibodies against endometrial glycoproteins or against "progestin dependent endometrial protein" (PEP) were found in any serum or peritoneal fluid sample. Levels of PEP were not different in serum from women with moderate to severe endometriosis (n = 6), with mild endometriosis (n = 21), or from disease-free cycling controls (n = 19). PEP levels in peritoneal fluid from mild endometriosis and from controls did not differ but were elevated ten times in fluid obtained in the secretory phase from women with moderate to severe disease. This suggests that PEP levels in peritoneal fluid reflect the extent of ectopic endometrial growth. The salient finding was a heretofore undescribed protein (mol wt 70,000) in secretory phase peritoneal fluid samples (18/20) and its absence during the proliferative phase (0/35).
