Özet

Cytomegalovirus (CMV) can be a cause of fetal morbidity and mortality among approximately 1% of pregnancies. With an aim to detect CMV antigenemia among 51 pregnant women with/without clinically diagnosed abnormalities and intrauterine growth retardation (IUGR) maternal and fetal samples either prenatal (n:22) or postpartum (n: 29) were obtained between 17-42weeks of gestation to analyze anti-CMV IgG, IgM antibodies and cytoplasmic or nuclear CMV antigens. Cytoplasmic and nuclear CMV antigenemia was detected among 19.6% and 11.8% of maternal samples. These values were 29.4% and 17.6% for fetal samples. Among both maternal and fetal samples, there was a 100% correlation when IgG and IgM were negative. The correlation for IgG and IgM positivity was not present among maternal samples since cytoplasmic (37.5%) and nuclear (25%) antigens could not be demonstrated in spite of immunity. Cytoplasmic and nuclear CMV antigens were detected within fetal samples fromsubjects presenting maternal immunoglobulin positivity, clinical abnormality and clinically normal findings (50, 32, 16.7% and 50, 16, 5.6%) respectively. In conclusion, immunocytochemical detection of CMV antigenemia improves CMV infection diagnosis which may be associated with clinical abnormalities/IUGR.
