2015年3月6日 更新者:GlaxoSmithKline
Case-control Study to Evaluate the Vaccine Effectiveness of RotarixTM Against Rotavirus Severe Gastroenteritis Among Hospitalised Children Aged 12 Weeks to < 5 Years, in Venezuela
This study aims to estimate the effectiveness of Rotarix™ vaccine against Rotavirus severe gastroenteritis (RV SGE) among hospitalised children aged between 12 weeks and < 5 years, in Venezuela and to assess the current disease burden after introduction of the vaccine.
調査の概要
詳細な説明
The data generated in this study will be useful for public health officers and policy makers in confirming the country-wide public health benefit of Rotarix™.
No vaccine will be administered during this study.

調査対象母集団
Children aged 12 weeks to < 5 years, hospitalised for SGE in the study hospitals.
説明
Inclusion Criteria:
For SGE subjects:
- A male or female child aged 12 weeks to < 5 years at the time of hospital admission/ ED stay. The subject becomes ineligible on the fifth birthday.
- Subject admitted to (or who will have an ED stay at) the study hospital(s) for SGE during the study period.
- Onset of SGE ≤ 14 days prior to admission/ ED stay.
- Written/thumb printed informed consent obtained from the parent(s)/legally acceptable representative(s) (LAR (s)) of the subject.
For Cases:
• Laboratory confirmed (i.e. by ELISA) RV-positive stool sample collected at hospital admission/ ED stay or during the first 48 hours of hospitalisation.
For Controls:
- Subject admitted to (or who will have an ED stay at) the same study hospital(s) for SGE as that of the case during the study period.
- Laboratory confirmed (i.e. by ELISA) RV-negative stool sample collected at hospital admission/ ED stay or during the first 48 hours of hospitalisation.
- Subjects born within ± 2 weeks from the date of birth of the case.
Exclusion Criteria:
For SGE subjects:
- Child in care.
- Hospitalisation is unrelated to GE.
- Onset of SGE > 48 hours after admission to (or ED stay at) the hospital.
- Subject has digestive tube anomalies, chronic gastrointestinal disease or uncorrected congenital abnormalities.
- Subject with immunodeficiency.
- Subjects who live out of the federative entity where hospital(s) are located.
For Controls:
• Subject has previously participated as case in this study.

Cases
Children hospitalised for SGE, aged 12 weeks to < 5 years at the time of hospital admission/ED stay and whose stool samples test positive for RV by enzyme linked immunosorbent assay (ELISA) at a GSK designated laboratory.
|
Stool samples will be collected from all children enrolled in the study, within 48 hours of admission to the hospital/ ED.
Stool samples will be tested to determine the presence or absence of rotavirus (RV).
Additionally, for RV-positive cases, the stool samples will be tested to determine the RV genotypes.
|
|
Controls
Children hospitalised for SGE, aged 12 weeks to < 5 years at the time of hospital admission/ ED stay, whose stool samples test negative for RV by enzyme linked immunosorbent assay at a GSK designated laboratory and who will be matched to the cases by date of birth and the hospital of admission/ ED stay.
|
Stool samples will be collected from all children enrolled in the study, within 48 hours of admission to the hospital/ ED.
Stool samples will be tested to determine the presence or absence of rotavirus (RV).
Additionally, for RV-positive cases, the stool samples will be tested to determine the RV genotypes.
