Molecular Epidemiology of Rotavirus Diarrhea Among Infants and Young Children Attending Maua Methodist Hospital, Kenya
Rotavirus is the most common cause of severe infantile diarrhoea disease in infants and young children below five years worldwide. It is associated with high cases of morbidity and mortality and it is estimated that up to 600,000 deaths in young children occur annually in the less developed countries and approximately 150,000-200,000 deaths occur in Africa alone. In Kenya, most rotavirus surveillance work has been done in Nairobi (an urban setting). Other parts e.g eastern Kenya, limited data is available and hence the prevalence and burden of rotavirus disease is under-estimated. We therefore hypothesize that rotavirus prevalence is high in Meru,Maua (a rural setting)and hence we designed a study to evaluate this.
This is a prospective study to determine, the rotavirus disease burden and epidemiology in infants and children with severe diarrhoea hospitalized in three sentinel hospital in the eastern part of Kenya (Maua Methodist hospital) will be carried out during the period January 2009 to December 2010.
Faecal samples will be collected from infants and children admitted with acute diarrhoea and screened first for the presence of human serotype A rotavirus antigen using commercially available enzyme linked immunosorbent assay kit (ELISA).
The positive samples will be evaluated by sodium dodecyl polyacrylamide gel electrophoresis (SDS-PAGE) to determine the electropherotypes and genotyped using reverse transcriptase polymerase chain reaction (RT-PCR) on VP7 and VP4 gene.
These data/ results generated from this project will add crucial information on the rotavirus strains circulating in the eastern part of Kenya.
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Molecular Epidemiology of Rotavirus Diarrhea Among Infants and Young Children Attending Maua Methodist Hospital, Kenya|
- Percentage prevalence of rotavirus positive cases [ Time Frame: 3 years ] [ Designated as safety issue: No ]
- Any novel rotavirus strain detected by sequencing [ Time Frame: 3 years ] [ Designated as safety issue: No ]
Biospecimen Retention: Samples With DNA
The positive samples will be evaluated by sodium dodecyl polyacrylamide gel electrophoresis (SDS-PAGE) to determine the electropherotypes and genotyped using reverse transcriptase polymerase chain reaction (RT-PCR) on VP7 and VP4 gene and sequencing. Also, these positive samples will be retained for quality assurance and quality control.
|Study Start Date:||August 2009|
|Study Completion Date:||September 2012|
|Primary Completion Date:||September 2012 (Final data collection date for primary outcome measure)|
children and infants (less than 5 years of age) presenting with severe diarrhea will be enrolled
Other: oral rehydration therapy for diarrhea cases
Since rotavirus infection is a viral infection with no drug remedy, diarrhea cases will be managed according to the standard WHO protocol for the management of diarrhea. This will include oral rehydration treatment.
