Abstract

Intercellular adhesion molecule 1 (ICAM-1) expression and upregulation induced by pro-inflammatory cytokines may be of interest in defining human response to inflammation and infection. This study was initiated to determine the levels of ICAM-1 in sera and amniotic fluid of cases of premature rupture of membranes (PROM). Serum and amniotic fluid ICAM-1 levels were determined by ELISA in 33 cases of PROM and 10 cases of normal pregnancies of matched gestational age (controls). Both serum and amniotic fluid ICAM levels were significantly elevated in 76% and 85% of cases of PROM with mean fold increments of 3.13 and 3.95, respectively. This elevation was associated with intra-amniotic infection which was detected by microbiological culture and histopathological evidence of chorioamnionitis. Increased ICAM-1 in cases of PROM may be attributed to neutrophil activation and ICAM-1 expression on fetal membranes and mononuclear cells of amniotic fluid. These results demonstrate that determination of ICAM-1 may be a valuable biomarker for early detection of acute chorioamnionitis and the possibility of PROM.
