[Importance of plasma PMN granulocyte elastase concentration determination in pregnant patients with premature rupture of fetal membranes].
The aetiology of preterm rupture of membranes is not yet completely understood. Local infections of the vagina and cervix have attracted special attention during the last years. Ascending infection with subsequent chorioamnionitis is a common complication of preterm rupture of membranes. Recognition of the beginning of a chorioamnionitis is usually based on clinical symptoms and laboratory findings like white blood cell count and C-reactive protein. The purpose of this study was to find out the diagnostic value of elastase, a protease of polymorphonuclear granulocytes, which is known to be involved in inflammatory processes. Fifteen out of thirty-three patients with preterm rupture of membranes developed a chorioamnionitis. Elastase plasma concentration levels > or = 32 ng/ml one day before delivery showed a significant correlation (p = 0.02) to the development of a chorioamnionitis. At this time neither white blood cell count, nor rectal body temperature showed significant correlations. Low elastase levels do not exclude an infection, whereas high levels indicate an infectious process. We conclude that elastase is a relevant marker of chorioamnionitis.
