RESCEU: Defining the Burden of RSV Disease
REspiratory Syncytial Virus Consortium in EUrope (RESCEU) Study: Defining the Burden of Respiratory Syncytial Virus (RSV) Disease.
This observational study will determine the burden of RSV disease in at least 2000 healthy infants over 6 years until November 2026. The study will determine the incidence of acute respiratory tract infection (ARTI) associated with RSV, of medically attended ARTI and RSV related hospitalisation.
Mortality (RSV associated and all-cause) through all RSV seasons and the health care costs, resource use and Health Related Quality of Life will also be determined. The study also aims to determine important risk factors for RSV infection (by severity and healthcare utilisation.
Study Overview
Status
Intervention / Treatment
Detailed Description
Infants will be recruited into one of two cohorts:
Passive (around 1800 participants) - Demographic data will be collected at inclusion and a parental questionnaire at one year of age. Infants admitted to a hospital with an acute respiratory tract illness will be followed up to the age of 3 years or 6 years with additional consent.
Active (around 200 participants) - Demographic data, parental questionnaire and the following samples will be collected at inclusion; blood, nasopharyngeal swabs, urine and stool. During the infants first RSV season (Oct - May) weekly phone contact will monitor respiratory symptoms. Infants with respiratory symptoms associated with RSV (confirmed by point of care testing) will have further samples of blood, nasopharyngeal swabs, urine and stool collected at the time of infection and 7 weeks later. Infants in the active cohort will be followed up for up to 3 years or 6 years with additional consent.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Active
200 infants enrolled; family demographics collected and samples at day 5 (venepuncture, nasopharyngeal swab, urine and stool), actively followed up through their first RSV season for signs of respiratory symptoms.
If respiratory symptoms are due to RSV infection (by point of care testing) samples as taken at day 5 are repeated at time of infection and again 7 weeks later.
Annual questionnaire enquiring into respiratory illness, hospitalisations and family health and health quality of life, for up to 3 years.

Passive
1800 infants enrolled; family demographics collected.
Questionnaire follow up at 1 year of age enquiring into respiratory illness, hospitalisations and family health and health quality of life.
If infant was hospitalised in first year of life, follow up will continue for up to 3 years.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The relationship between infant RSV infection of different severity and school age asthma
Time Frame: Year 6
|
Symptoms of asthma, diagnosis and use of asthma medication will be measured by parental questionnaire/medical records.
|
Year 6
|
Number of RSV associated Acute Respiratory Tract infections (ARTI) during the first year of life, to include the number of medically attended ARTI (MA-ARTI) and hospital admissions related to RSV.
Time Frame: Year 1
|
RSV associated ARTI confirmed on nasopharyngeal swabs during home visits for all ARTI episodes during the RSV season, for testing using a RSV POC (Point of Care) test and reverse transcription-polymerase chain reaction (RT-PCR). Participants will be screened for hospital admission for respiratory symptoms by parental questionnaire at age 1 year. If positive, RSV will be confirmed by accessing hospital records. Medically attended RSV infection is defined as any medical care for RSV infection (defined as above) |
Year 1
|
The relationship between infant RSV infection of different severity and school age asthma
Time Frame: Year 4
|
Symptoms of asthma, diagnosis and use of asthma medication will be measured by parental questionnaire/medical records.
