UNLABELLED: The main markers of intrauterine infection: C-reactive protein and white blood cell count are dependent on medical management as steroids or antibiotics therapy. Granulocyte elastase is independent variable from influence of tocolysis, steroids, antibiotics, chemiotherapeutics, hours since PROM. The aim of the study was to evaluate and compare the usefulness of determination granulocyte elastase, (EG) C-reactive protein (CRP) and white blood cell count (WBC) in prediction of chorioamninitis in pregnant women after premature rupture of fetal membranes. MATERIALS AND METHODS: 67 women with single pregnancy between 24-36 week of gestation after PPROM were included into the study group. All women were managed expectantly (tocolysis, antibiotics, steroids, intravaginal chemiotherapeutics, bed rest), maternal and fetal (KTG, USG) vital signs were monitored every day. EG, CRP and WBC blood test were performed every day. Histopathologic examinations of all placentas were performed for chorioamnionitis confirmation or exclusion. Normal range for EG--88 micrograms/l, CRP--15 micrograms/l, WBC--15 x 10(9). RESULTS: The usefulness of granulocyte elastase plasma serial determination as biochemical marker of chorioamnionitis in cases of PPROM was confirmed: sensitivity--100%, specificity--33%, PPV--64.9%, NPV--100% in comparison with CRP: sensitivity--27%, specificity--80%, PPV--62.5%, NPV--47% and white blood cell count: sensitivity--27%, specificity--66.7%, PPV--50%, NPV-42.5%. CONCLUSIONS: We confirmed statistical correlation (p < 0.001) between granulocyte elastase plasma level > 88 micrograms/l and histological signs of intrauterine infection in pregnant women after PPROM. Granulocyte elastase determination in plasma is most sensitive indicator of histologic confirmed chorioamnionitis.
