A prospective clinical study of rotavirus diarrhoea in young children
Insights
Rotavirus diarrhea in young children is often more severe than other causes, presenting with dehydration and acidosis. Identifying key clinical signs can aid in early diagnosis of rotavirus gastroenteritis.
Area of Science:
- Pediatrics
- Infectious Diseases
- Gastroenterology
Background:
- Acute diarrhea is a common illness in children aged 6 to 36 months.
- Differentiating rotavirus gastroenteritis from other causes is crucial for appropriate management.
- Rotavirus is a leading cause of severe diarrheal disease in infants and young children globally.
Purpose of the Study:
- To compare the clinical and laboratory features of acute rotavirus diarrhea with non-rotavirus diarrhea in young children.
- To identify characteristic clinical and laboratory findings associated with rotavirus infection.
- To evaluate the utility of specific criteria for the presumptive diagnosis of rotavirus diarrhea.
Main Methods:
- A comparative study involving 96 children with acute rotavirus diarrhea and 63 children with acute non-rotavirus diarrhea.
- Patients were aged between 6 and 36 months.
- Clinical assessments included dehydration, acidosis, vomiting, fever, neutropenia, and stool analysis (sugar, mucus, occult blood, leucocytes).
Main Results:
- Rotavirus-associated diarrhea predominantly occurred between January and June (80% of cases).
- Rotavirus cases generally presented with more severe diarrhea, characterized by dehydration, acidosis upon admission, vomiting, and fever.
- Specific indicators for rotavirus included neutropenia and the presence of sugar in stools (Clinitest ≥ 0.5%). No significant differences were observed in respiratory symptoms or stool presence of mucus, occult blood, or leucocytes.
Conclusions:
- Clinical features such as dehydration, acidosis, vomiting, fever, neutropenia, and stool sugar are indicative of rotavirus diarrhea in young children.
- The duration of symptoms and occurrence of respiratory symptoms did not differ significantly between rotavirus and non-rotavirus groups.
- A combination of identified clinical and laboratory criteria can assist in the presumptive diagnosis of rotavirus gastroenteritis.
Abstract:
The clinical and laboratory features of 96 children aged 6 to 36 months with acute rotavirus diarrhoea were compared to findings on 63 children of the same age with acute non-rotavirus diarrhoea. Of the rotavirus-associated cases 80% occurred between January and June. In general, the diarrhoea was more severe in these patients than in the others, but no difference was seen in duration of symptoms. Clinical features characteristic of rotavirus-associated cases included: dehydration and acidosis upon admission, vomiting, fever, neutropenia and sugar in the stools (Clinitest greater than or equal to 0.5%). In contrast, no difference was seen in the occurrence of respiratory symptoms (53% in the rotavirus, 62% in the non-rotavirus group), or in the presence of mucus strands, occult blood or leucocytes in stools. A combination of the above criteria may be helpful in the presumptive diagnosis of rotavirus diarrhoea.
