Brief Summary

The VRS (Respiratory Syncytial Virus) study group in Lyon is a working that aims to understand, predict and prevent the burden of disease caused by human respiratory syncytial virus (RSV) infection in infants. Incidence of RSV-associated hospitalization in the first year of life was estimated at 14.5 (95% CI 13.4-15.6) per 1000 births in a cohort study in Lyon, France. Related direct medical annual costs were estimated for this cohort at 364,269€, mostly attributed to children born during the RSV season (231,959€) and children born premature (108,673€). This study will combine existing hospital specimens and databases to determine the respective role of socio demographic factors, clinical risk factors, level of cord specific antibody at birth, and virus characteristic in the Respiratory Syncytial Virus (RSV) Hospitalization outcome in Infants. Regarding the introduction of a new RSV vaccine and RSV-specific neutralizing antibodies, these data are of prime importance to guide future vaccine policies.

Outcome Measures

Primary Outcomes (2)

  • Number of cases included in the cohort with RT-PCR (Retrotranscription) confirmed RSV hospitalization occurring from birth until the age of 1 year

    Cases were defined as a new admission to one of the conventional pediatric hospital departments with a RSV positive sample during the hospital stay the first 3 years of life.

    1 year after inclusion

  • Number of cases included in the cohort with RT-PCR confirmed RSV hospitalization occurring from birth until the age of 3 years.

    Cases were defined as a new admission to one of the conventional pediatric hospital departments with a RSV positive sample during the hospital stay the first 3 years of life.

    3 years after inclusion

Secondary Outcomes (2)

  • Quantitative level of anti-RSV IgG measure

    3 years after inclusion

  • Quantitative level of anti-RSV IgG (Immunoglobulin G) measure

    3 years after inclusion

Study Arms (1)

Passive Birth Cohort

This will be a multicenter, prospective, observational cohort study conducted across the Lyon Public hospital maternity (HFME : Hospital for women, mother and children, Croix-Rousse, Lyon-Sud) recruited from the general population. Infants born between October 2019 and march 2020. At birth the remains (after diagnosis use) of cord blood samples will be store. Groups of RSVh cases and control will be class at one year of age using the hospital data (RSV must be confirmed by RT-PCR). Parents will be informed of the protocol. If enrolled available hospital data will be use and RSV serology testing perform on the store blood cordon.
