Introduction: Disturbances in cytokine networks are believed to be associated with increased risk of adverse pregnancy complications. Methods: Plasma samples collected from pregnant women with preterm deliveries, high-risk pregnancy complications including postpartum hemorrhage, hypertensive disorders, and multiple gestations, and normal pregnancies were analyzed at different periods throughout gestation and postpartum. Interleukin (IL) 1beta , IL-6, IL-8, IL-10, tumor necrosis factor alpha, and antiprotein Z antibody levels were measured by enzyme-linked immunosorbent assay. Results: The IL-6 levels in preterm delivery patients were elevated during pregnancy with statistically significant differences observed at 21 to 32 weeks (P .01) and 33+ weeks (P .001). The IL-10 levels were increased in normal pregnancy at all time points compared to the other patient groups (P .05). The TNF-alpha levels were elevated in the high-risk pregnancy group versus normal controls (P .001 at 21 weeks and P .05 at 21-32 weeks). Conclusion: Analysis of the maternal plasma for elevated IL-6 and reduced IL-10 levels may be of value in the early prediction of pregnancy complications. |
