Peritoneal fluid prostaglandins and prostanoids in women with endometriosis, chronic pelvic inflammatory disease, and pelvic pain

Peritoneal fluid obtained at laparoscopy from 49 women was measured for its content of prostaglandin E2 (PGE2), prostaglandin F2 alpha (PGF2 alpha), 6-keto-prostaglandin F1 alpha (6-KF), and thromboxane B2 (TxB2) by specific radioimmunoassays. In normal women (n = 10), the concentrations of prostaglandins in peritoneal fluid were (mean +/- SE): PGE2 = 0.79 +/- 0.26, PGF2 alpha = 0.60 +/- 0.18, 6-KF = 0.48 +/- 0.19, and TxB2 = 0.23 +/- 0.09 ng/ml; in women with endometriosis (n = 16): PGE2 = 1.43 +/- 0.72, PGF2 alpha = 1.52 +/- 0.59, 6-KF = 3.32 +/- 0.71, and TxB2 = 1.14 +/- 0.69 ng/ml; in women with chronic pelvic inflammatory disease and/or obstructed tubes (n = 19): PGE2 = 1.94 +/- 1.04, PGF2 alpha = 1.20 +/- 0.61, 6-KF = 1.55 +/- 0.40, and TxB2 = 0.64 +/- 0.24 ng/ml; in women with pelvic pain without any visible pathologic condition (n = 4): PGE2 = 1.11 +/- 0.66, PGF2 alpha = 0.73 +/- 0.55, 6-KF = 1.35 +/- 0.35, and TxB2 = 0.39 +/- 0.17. The mean volumes of peritoneal fluid recovered were 10 to 16 ml and were not significantly different between the groups. Except for a significantly elevated concentration of 6-KF in the peritoneal fluid of women with endometriosis compared to normal women (p = less than 0.02), the prostaglandins measured did not differ significantly between the groups of women studied. The possible significance of elevated 6-KF in the peritoneal fluid of women with endometriosis is discussed.     

Increased nitric oxide in peritoneal fluid from women with idiopathic infertility and endometriosis.

OBJECTIVE: To verify whether nitric oxide in peritoneal fluid is associated with endometriosis and infertility. STUDY DESIGN: Twenty-five women with idiopathic infertility and 38 with endometriosis were recruited, and 18 cases of uterine myomata and 2 cases of ovarian cyst served as controls. Peritoneal fluid samples were aspirated from the pouch of Douglas during laparoscopy or laparotomy. Metabolites of nitric oxide (nitrite and nitrate) in peritoneal fluid were determined by a method using nitrate reductase and the Griess reaction. RESULTS: Peritoneal concentrations of nitrate/nitrite in both infertile women (42.02 +/- 12.98 mmol/L) and patients with endometriosis (41.75 +/- 16.42 mmol/L) were significantly higher than that in controls (33.96 +/- 13.07, P < .05 for both). No significant difference in peritoneal nitrate/nitrite level was found between infertile women and patients with endometriosis (P > .5). Peritoneal levels of nitrate/nitrite were comparable among patients with endometriosis at different stages (P > .5). Patients with endometriosis had more peritoneal fluid than controls and idiopathic infertile women, while controls and idiopathic infertile women had comparable amounts of peritoneal fluid. CONCLUSION: An increased peritoneal level of nitric oxide is a common alteration in endometriosis, endometriosis-associated infertility and idiopathic infertility and may be associated with the pathogenesis of these diseases.     

Serum and peritoneal fluid immunological markers in adolescent girls with chronic pelvic pain

The aim of this study was to determine serum and peritoneal interleukin (IL)-2, IL-4, and monocyte chemotactic protein-1 levels as diagnostic markers of endometriosis in adolescent girls. The design of the study encompassed 50 adolescent girls, aged 13 to 19 years after menarche, with chronic pelvic pain who qualified for diagnostic laparoscopy. The patients were allocated into 2 groups: group I (endometriosis) consisted of subjects with diagnosed endometriosis (n = 33, 66%) and group II (control) whose laparoscopic examinations revealed no evidence of endometriosis (n = 17, 34%). IL-2, IL-4, and Monocyte chemotactic protein 1 concentrations in serum and peritoneal samples were assessed using commercially available human enzyme-linked immunosorbent assay kits. The results were analyzed statistically with the Statistica 8.0 computer software. The value of P < 0.05 was the level of statistical significance. The results in adolescents with endometriosis had significantly higher concentrations of serum IL-4 (3.90 ± 1.58 pg/mL vs. 3.04 ± 1.72 pg/mL; P = 0.04) and peritoneal fluid IL-4 (5.03 ± 8.92 pg/mL vs. 2.74 ± 1.11 pg/mL; P = 0.03), and lower peritoneal fluid IL-2 (92.44 ± 292.75 pg/mL vs. 174.23 ± 389.77 pg/mL; P = 0.01) compared with the control. In a receiver-operating characteristic analysis, serum IL-4 as well as peritoneal fluid IL-2 and IL-4 provided the best discriminative ability between subjects with endometriosis and controls. Using cutoff points for serum IL-4 (3.00 pg/mL), peritoneal fluid IL-2 (21.00 pg/mL) and IL-4 (2.7 pg/mL), relatively high odd ratios were obtained in the prediction of endometriosis in adolescents (3.2; 6.4; 3.3). The Serum IL-4, peritoneal IL-2 and IL-4 provided a good method of discrimination between subjects with endometriosis and controls.

The concentration of 13,14-dihydro-15-keto prostaglandin F2 alpha and prostaglandin E2 in peritoneal fluid of infertile patients with and without endometriosis

Prostaglandin F2 alpha (PGF2 alpha) metabolite (13,14-dihydro-15-keto PGF2 alpha) and prostaglandin E2 (PGE2) were assayed in the cul-de-sac fluid aspirated from 15 patients with endometriosis, in saline peritoneal washings of 5 patients with unexplained infertility, and in 5 control subjects. The fluid from the cul-de-sac of patients with endometriosis showed wide variations in the concentrations of PGF2 alpha metabolite and PGE2. There was no correlation between the concentration of these prostaglandins (PGs) and the stage of the cycle. Saline peritoneal washings from patients with unexplained infertility had significantly higher concentrations of PGF2 alpha metabolite than the control subjects. The concentration of PGE2 in the saline peritoneal washings was higher in the group with unexplained infertility than in the control group; however, the difference was not significant. The concentration of PGF2 alpha metabolite and PGE2 in the peritoneal saline washings from patients with unexplained infertility were no different from the concentrations of these PGs in the peritoneal fluid (PF) from patients with endometriosis. PG concentration in PF of infertile patients with or without endometriosis is a new variable for evaluation in these patients.     

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.
