Abstract
OBJECTIVE: The rates of seropositivity, seroconversion and fetal infection with human cytomegalovirus were analyzed in pregnant women and newborn cord blood in this study. The relationships between maternal age, parity, cytomegalovirus serology and polymerase chain reaction results were evaluated. MATERIALS AND METHODS: A total of 217 pregnant women attended our pregnancy clinic between April 2004 and October 2005. During each trimester, 5 cc of maternal blood was obtained and 5 cc of cord blood was collected after birth. An enzyme-linked immunosorbent assay (ELISA) was used to assess these samples for the presence of human cytomegalovirus protein pp65 antigen (in leukocytes) and cytomegalovirus DNA (in plasma). RESULTS: The mean age of the pregnant women in our study was 28.1±5.3 years. No seroconversion was observed. Among the pregnant women, 212 (97.7%) were IgG positive, and 29 (13.4%) were IgM positive. Five of the pregnant women were positive for IgM alone (2.3%), whereas 24 (11.3%) were positive for both IgM and IgG. The 29 IgM-positive patients were reevaluated using the polymerase chain reaction, and no seropositivity was found. None of the cord blood samples were IgM positive, whereas 211 (97.3%) were IgG positive. There was no significant correlation between parity and seropositivity (p=0.487). The relationship between human cytomegalovirus seropositivity and maternal age was evaluated by dividing the pregnant women into two groups, with a cut-off age of 35 years. There was a significant difference in seropositivity between these two groups (p=0.045). CONCLUSION: Clearly, there is no need to screen pregnant women for Human cytomegalovirus (HCMV) in the Malatya region. Confirming serology results using the polymerase chain reaction and antigenemia testing to detect false positive results offers the advantage of avoiding unnecessary invasive interventions.
