To investigate retrospectively the prognostic significance of maternal, fetal, and neonatal parameters and clinical outcome in 150 HCMV congenital infections during the period 1995–2009. HCMV fetal infection was investigated in amniotic fluid and fetal blood samples. HCMV congenital infection was confirmed in newborn urine and blood samples. Symptomatic infection was defined in HCMV‐infected fetuses and in infected newborns on the basis of physical and instrumental findings. Follow‐up at 3, 6, 12 months, and then annually up to school age, included clinical evaluation, funduscopic, audiologic, neurologic, and cognitive assessment. Overall, 122/150 (81.3%) newborns were asymptomatic and 28/150 (18.7%) were symptomatic at birth. The best prognostic maternal parameter of symptomatic infection at birth was gestational age at infection ( P = 0.037). The best fetal virological markers were HCMV DNA levels in amniotic fluid ( P < 0.001), antigenaemia levels ( P = 0.007), HCMV DNA levels in blood ( P = 0.004), and HCMV‐specific IgM index values ( P = 0.002). The only significant neonatal parameter was HCMV DNA level in blood [ P = 0.006; OR, 3.62 (95% CI, 1.46–8.97)]. Symptoms at birth correlated significantly with long‐term sequelae ( P = 0.021). A trend towards a risk of sequelae in early (n = 15/58 examined) versus late (n = 6/57 examined) maternal infection was documented. The risk of symptomatic congenital infection at birth increased linearly with the number of significant maternal, fetal, and neonatal parameters. J. Med.
