Summary: | This study was conducted in order to investigate the usefulness of granulocyte elastase levels as predictive factors in the onset of perinatal infections. The subjects were 41 patients who delivered within 48 h after amniocentesis after giving their informed consent. The relationship between cervical granulocyte elastase (Cx-E), serum C-reactive protein (CRP) and amniotic fluid granulocyte elastase (Af-E), and placental infections and neonatal infections was comparatively investigated. In some cases, gastric juice granulocyte elastase in neonates (Gj-E) was measured, and the correlation by site was investigated. Elastase levels were not used as a management protocol. In predicting neonatal infections, diagnostic efficacy (sensitivity x specificity) of placental infections (0.97) and abnormal Af-E (0.79) were superior to those of abnormal Cx-E (0.40) and abnormal CRP (0.49). There was no correlation between Cx-E and Af-E or between Cx-E and Gj-E; however, a very close correlation was noted between Af-E and Gj-E. In predicting abnormal amniotic fluids, Cx-E (> or = 1.2 micrograms/ml) + CRP (> or = 1.0 mg/dl) had the highest diagnostic efficacy with 0.58. These findings demonstrate that Af-E is a good index for predicting the onset of neonatal infections. In predicting abnormal amniotic fluid, it might be advisable to consider amniocentesis in order to diagnose intrauterine infections, when both Cx-E and CRP show abnormal levels. |
