Purpose
To determine the frequency of obstetrical adverse events and clinical outcome in infants following antenatal hyperimmune globulin (HIG) treatment for primary cytomegalovirus (CMV) infection in pregnancy.
Methods
Data from 50 women including three twin pregnancies were retrospectively evaluated. Primary infection was defined by seroconversion or the presence of CMV-specific IgM and low IgG avidity. All women received two or more infusions of HIG (200 U/kg). Congenital CMV (cCMV) infection was diagnosed by detection of CMV in amniotic fluid and/or neonatal urine. We compared gestational age (GA) at birth, head circumference (HC) and birth weight (BW) of infants in our study cohort with those of live-born infants delivered in our clinic between 2015 and 2016.
Results
Median gestational age at time of maternal CMV diagnosis was 13 weeks. One-hundred-forty-one maternal HIG doses were given. No HIG-related severe adverse reactions occurred. Preterm birth rate was 4.2% (2/47) in singleton pregnancies. None of the neonates had birth weight or head circumference < 3rd percentile (< 3P) for gestational age. There was no statistically significant difference regarding GA, BW and HC between our study cohort and the total population of live-born infants. The frequency of CMV-related sequelae in infants with cCMV infection was 10.5% (2/19) (one with bilateral hearing loss and one with mild motoric delay), both cases following first trimester maternal infection.
Conclusion
Antenatal HIG treatment was well tolerated and not associated with prematurity or decreased birth weight. HIG application might have a favorable effect on the clinical course of congenital CMV infection.
