Clinical Trial Summary

The main objective of this study is to validate , in the neonatal period, a prognostic score for the development of neurosensorineural sequelae at 1 year and at 2 years in neonates infected in utero by cytomegalovirus. This score will be based on clinical, imaging and biological criteria .

The second objective of the study is to estimate the prevalence of this infection in France and to describe its epidemiology through the screening of 12,000 consecutive neonates.

Description:

Infection with cytomegalovirus (CMV) is the most frequent cause of congenital neurological handicap of infectious origin in industrialized countries. Around 10% of infected neonates have symptoms and more than 50% of those will develop long term neurological sequelae and sensorineural hearing loss. Among asymptomatic infected neonates 10 to 15% will ultimately develop hearing loss. To establish the prognosis of infected neonates remains difficult and the purpose of the study is to better define early prognosis factors The true burden of CMV congenital infection is unknown in France: the prevalence of the infection as well as the description of its epidemiology (proportion of symptomatic and asymptomatic cases, rate of long term sequelae, proportion of cases following primary or secondary maternal infections) are unknown.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Prognostic value of neonatal markers (clinical, imaging and biological) for the development of neurosensorial sequelae at 1 year of age	Assessment will include standardised clinical evaluation, cerebral ultrasound, cerebral MRI, audiometric tests, developmental tests, virological tests (viral load in blood and saliva) and immunological tests (cluster of differentiation 4 (CD4), cluster of differentiation 8 (CD8), Natural Killer (NK) and cytokines).	One year
Secondary	to evaluate the prevalence of congenital CMV in France:	screening by CMV PCR in a saliva sample collected in delivery room will be proposed to all mothers with a live birth neonate born in the Necker or Poissy	At birth
Secondary	Prognosis value of antenatal imaging	To compare neurodevelopmental and sensorineural sequelae at one year with the result of antenatal imaging (ultrasound and MRI)	one year
Secondary	Prognostic value of the periodic measurement of the kinetics of viral load shedding	To evaluate the prognostic value of the kinetics of CMV viral load in blood and in saliva from birth to 1 year old for the occurrence of neurodevelopmental and sensorineural sequelae	One year
Secondary	neurodevelopmental and sensorineural sequelae according to the type of maternal infectionsequelae	Compare the proportion of neurodevelopmental and sensorineural sequelae according to the type of maternal infection (primary or secondary).	One year
Secondary	Prevalence and description of congenital CMV infection in 10,000 French neonates	Screening of congenital CMV infection in a population of 10,000 consecutive newborns in 2 French maternities	1 week
