Pathogenesis.

Abstract

There are many hypotheses concerning the pathogenesis of endometriosis, though no single theory can explain all cases. It is likely that several mechanisms are involved. Early studies concentrated on the histogenesis of the endometriotic lesion. Recent evidence has implicated components of the immune system in the pathogenesis of endometriosis. This review considers the evidence for different theories of the histogenesis of endometriosis and discusses possible immune factors that may be involved in the pathophysiology of the disease.

Do peritoneal catheters remove pro-inflammatory cytokines after cardiopulmonary bypass in neonates?

BACKGROUND: Cardiopulmonary bypass (CPB) in neonates induces a cytokine-mediated capillary leak syndrome that can cause organ dysfunction. Removing harmful cytokines after CPB may attenuate this response. This study measured the concentrations of serum and peritoneal fluid (PF) cytokines after CPB to determine if harmful cytokines can be removed with peritoneal catheters. METHODS: Neonates (n = 18) had cardiac surgery using CPB with circulatory arrest. Peritoneal catheters were placed at the end of surgery to drain excess fluid. Serum samples were obtained before and after CPB, and PF after CPB. Cytokines were measured by enzyme-linked immunosorbent assay. RESULTS: Tumor necrosis factor-alpha and interleukin-1beta (IL-1beta) were not detected in any serum or PF sample. Serum concentrations of IL-6, IL-8, and IL-10 increased significantly after CPB. PF concentrations of IL-6 and IL-8 exceeded serum concentrations, whereas IL-10 concentrations were higher in the serum. There was a significant negative correlation between serum and PF concentrations of IL-6 after CPB (r = -0.63; p<0.05). CONCLUSIONS: PF has very high concentrations of the proinflammatory cytokines, IL-6 and IL-8, after CPB but not the antiinflammatory cytokine IL-10. The PF may be a depot for the harmful inflammatory cytokines after CPB, and removing the PF could lower serum concentrations.

Peritoneal fluid interleukin-6 in women with chronic pelvic pain.

OBJECTIVE: To determine the relationship between peritoneal fluid concentrations of interleukin-6 (IL-6) and chronic pelvic pain symptomatology in women with adhesions, endometriosis, or no obvious intraperitoneal pathology. DESIGN: Clinical research study. SETTING: Healthy volunteers in an academic research environment. PATIENT(S): Reproductive-aged women undergoing laparoscopy for the diagnosis of pelvic pain, infertility, or sterilization were selected. INTERVENTION(S): Peritoneal fluid was collected at the time of the laparoscopy and later assayed for IL-6. Subjects completed a pelvic pain questionnaire, and operative reports were used to obtain the underlying diagnosis. MAIN OUTCOME MEASURE(S): Interleukin-6 concentrations. RESULT(S): No correlation between the presence or absence of pelvic pain, findings of adhesions or endometriosis, and the concentration of peritoneal fluid IL-6 was observed. CONCLUSION(S): The cytokine IL-6 does not seem to play a role in the genesis of chronic pelvic pain in women with adhesions or endometriosis.
