Brief summary: The objective of the trial is to investigate whether early treatment with oral valganciclovir of infants with both congenital cytomegalovirus infection and sensorineural hearing loss can prevent progression of hearing loss.

Detailed description: In the Netherlands all neonates are routinely screened for hearing during the first weeks after birth with the Otoacoustic Emissions (OAE) procedure. After the second refer an Automated Auditory Brainstem Response (AABR) is performed. The parents of all newborns, born at ≥ 37 weeks gestational age, that fail this AABR in the Netherlands (about 550 yearly) will be asked for consent for CMV-testing on the dried blood spots. Newborns diagnosed with congenital CMV and with confirmed SNHL (≥ 20 dB) are eligible for inclusion. After informed consent infants will be offered treatment before the age of 13 weeks (6 weeks valganciclovir 32 mg/kg daily dose; oral solution). Parents may decide to participate in the trial in the control group (no antiviral treatment). Infants will be monitored for leucopenia and liver- and kidney function. Inclusion will continue for at least 1.5 years, or until at least 40 infants have been included in the trial.

At age 20 months hearing and child development are assessed in the follow-up. Hearing will be assessed with Brainstem Evoked Response Audiometry with the Vivosonic Integrity. Child development will be assessed with the Bayley Scales of Infant Development III (official Dutch translation) and parents will fill in the Dutch Child Development Inventory (NCDI) which will give more detailed information on communicative development of their child. The hearing assessment and developmental examination will be fulfilled during a home visit. Viral loads in blood and urine will be monitored during antiviral treatment as well as twice in the control group.

This study will provide information on the percentage of infants with a congenital CMV infection who fail the neonatal hearing screening . The trial will show whether early treatment of congenital CMV infected children with hearing impairment prevents deterioration of hearing loss and to what extent. The outcome may lead to implementation of congenital CMV testing in the neonatal hearing screening program or possibly into the newborn blood screening.
