PROBLEM: To assess the usefulness of amniotic fluid (AF) granulocyte colony-stimulating factor levels (G-CSF) in chorioamnionitis (CAM) to predict neonatal sepsis.

METHOD OF STUDY: AF samples were obtained from term and preterm patients with (Group I) and without (Group II) CAM and were assayed for G-CSF levels. Patients with other infections were excluded. All AF samples were also tested for gram stain and cultures. The sensitivity, specificity, and predictive values of these parameters for diagnosing neonatal sepsis were assessed.

RESULTS: Positive AF cultures were the best predictors of neonatal sepsis in CAM, with a sensitivity of 67% and a positive predictive value (PPV) of 80%. Elevated AF G-CSF levels (>1,000 pg/ml) were poor predictors of neonatal sepsis with a sensitivity of 29% and PPV of 39%.

CONCLUSION: Even though AF G-CSF levels were markedly elevated in patients with CAM, they were poor predictors of subsequent neonatal sepsis.
