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.

Children aged 12 weeks to < 5 years, hospitalised for SGE in the study hospitals.

描述

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.

队列和干预

团体/队列
干预/治疗
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.
