Abstract
OBJECTIVE
To examine if amniotic fluid (AF) monocyte chemotactic protein-1 (MCP-1) concentrations are useful in the identification of intrauterine infection and pregnancy outcomes in preterm labor with intact membranes.
METHODS
The study population consists of 65 patients who received amniocentesis for preterm labor with intact membranes. Amniotic fluid was cultured for aerobic and anaerobic bacteria, as well as mycoplasmas. MCP-1 was determined by a sensitive and specific immunoassay. Fisher's exact test, Mann-Whitney U test, receiver operating characteristic curve, survival techniques, logistic regression, and Spearman correlation were used for statistical analysis.
RESULTS
(1) Patients with a positive amniotic fluid culture had a significantly higher median AF MCP-1 concentration than those with negative results (median, 9.0 ng/mL; range, 0.45-40.5 ng/mL; vs median, 0.82 ng/mL; range, 0.06-30.1 ng/mL; P<.01). (2) Patients with AF MCP-1 concentration of >1.9 ng/mL had a significantly shorter median interval to delivery, the higher rate of histologic chorioamnionitis, preterm delivery within 2 and 5 days, and the occurrence of congenital proven or suspected sepsis than did those with AF MCP-1 concentration of <1.9 ng/mL after adjustment for gestational age (P<.05). (3) There was strong correlation between AF MCP-1 concentrations and AF interleukin-6 concentrations (r=.881, P<.001).
CONCLUSION
AF MCP-1 determinations are useful in the identification of intrauterine infection, preterm delivery, and neonatal infectious complication in preterm labor with intact membranes.
