Insights
Rotavirus was detected in over half of juvenile diarrhea cases in Malaysia, primarily affecting children aged 6-24 months. Different rotavirus strains were linked to varying clinical symptoms, including dehydration and lethargy.
Area of Science:
- Virology
- Pediatrics
- Public Health
Background:
- Rotavirus is a leading cause of severe diarrheal disease in infants and young children globally.
- Understanding local rotavirus epidemiology and clinical manifestations is crucial for effective disease management and prevention strategies.
Purpose of the Study:
- To investigate the prevalence of rotavirus in juvenile diarrhea cases in eastern Malaysia.
- To characterize the rotavirus strains detected using polyacrylamide gel electrophoresis (PAGE).
- To correlate rotavirus subgroups with specific clinical features of diarrhea.
Main Methods:
- Prospective study over 2 months involving 69 cases of juvenile diarrhea.
- Rotavirus detection through excretion analysis.
- Rotavirus genome ribonucleic acid (RNA) electropherotyping using PAGE.
- Clinical data collection and analysis, including dehydration severity and lethargy.
Main Results:
- Rotavirus was identified in 51% (35/69) of juvenile diarrhea cases.
- The 6-24 month age group was most commonly affected.
- Four rotavirus electropherotypes were detected, with two predominant strains.
- Rotavirus subgroup 1 was associated with increased hypotonic dehydration and need for intravenous therapy.
- Lethargy was significantly more common in patients excreting rotavirus subgroup 2.
Conclusions:
- Rotavirus is a significant cause of juvenile diarrhea in eastern Malaysia.
- Distinct rotavirus subgroups exhibit different clinical presentations.
- Further research into rotavirus strain diversity and clinical impact is warranted.
Abstract:
Over a period of 2 months, 35 of 69 (51%) cases of juvenile diarrhoea studied in eastern Malaysia were associated with rotavirus excretion; rotavirus associated diarrhoea occurred most commonly in the 6-24 month age group. Polyacrylamide gel electrophoresis (PAGE) of genome ribonucleic acid showed that only 4 rotavirus electropherotypes could be detected. Of those, 2 predominated and 2 were detected only once each; one of these may have been a reassortment of the two predominant electropherotypes. Analysis of the clinical features of patients excreting rotavirus subgroup 1 or 2, determined by PAGE, demonstrated that rotavirus subgroup 1 was associated with more hypotonic dehydration and need for intravenous therapy: lethargy was significantly more common among those excreting rotavirus subgroup 2.
