OBJECTIVE: The purpose of this study was to determine if phospholipase A2 was detectable within vaginal fluid and to correlate its presence with the presence of common lower genital tract infection or microbial conditions.
STUDY DESIGN: Pregnant women were examined at the first prenatal visit with standard clinical evaluations and microbiologic cultures or tests. Vaginal fluid samples were evaluated for phospholipase A2 activity by means of a standardized enzyme fluorometric assay. Data were stratified to control for coexisting infections.
RESULTS: Phospholipase A2 activity was detected among 29.8% of women and was independently associated with the presence of bacterial vaginosis (p < 0.001), Trichomonas. vaginalis (p < 0.04), and Chlamydia trachomatis (p < 0.02). The percentage of women with phospholipase A2 activity and the level of activity was increased in the presence of more than one infection.
CONCLUSIONS: Elevated reproductive tract phospholipase A2 concentrations among pregnant women may play roles in the pathogenesis of preterm labor and birth. Identification of pregnant women with increased concentrations in vaginal fluid may allow for development of effective intervention strategies to reduce the risk of preterm birth.
