ABSTRACT
BACKGROUND:
Cytomegalovirus (CMV) is the leading cause of congenital infection worldwide. Up to 15%-20% of infected newborns will develop long-term sequelae such as hearing loss and neurologic abnormalities. The aim of this study was to investigate the prevalence of congenital CMV infection (cCMV) and associated clinical abnormalities in Spain.METHODS:
A prospective screening for cCMV by viral load in saliva was performed. Saliva samples were obtained within the first 72 hours of life in a maternity ward in Madrid (Spain), during a 1-year period. All positive screening tests were confirmed with viral load in urine. Clinical, laboratory, auditory, visual and cerebral imaging assessments were performed in all children with cCMV.RESULTS:
Of the 4097 neonates born during the study period, 3190 (78%) were included. CMV viral load in saliva was detectable in 24/3190 (0.75%) children, and congenital infection was confirmed in 15/3190 (0.47%, CI 95% 0.29%-0.77%). Positive predictive value was 62.5% (CI 95% 46.5%-76.1%). Two infants presented symptoms at birth. Eight (53.3%) children showed abnormalities in magnetic resonance imaging; most of them isolated white matter abnormalities. Newborns with abnormalities in magnetic resonance imaging showed higher viral loads in blood and saliva (P = 0.04).CONCLUSIONS:
One in 200 neonates born in our hospital presented a cCMV infection. CMV viral load in saliva has been shown to be a simple and highly accepted screening method but should be confirmed by CMV detection in urine. In spite of the fact that half of infected children had abnormalities in cerebral imaging, diagnosis during the neonatal period would have been impossible without a screening program in most cases.
