Clinical features in hospitalised children with acute gastroenteritis. Does the rotavirus syndrome exist?
Insights
Rotavirus gastroenteritis in children presents with severe vomiting and occurs in winter. However, clinical signs are not definitive for diagnosis, questioning a distinct rotavirus syndrome.
Area of Science:
- Pediatrics
- Infectious Diseases
- Virology
Background:
- Acute gastroenteritis is a common childhood illness.
- Rotavirus is a leading cause of severe gastroenteritis in young children.
- Accurate diagnosis of rotavirus gastroenteritis is crucial for management.
Purpose of the Study:
- To identify clinical characteristics differentiating rotavirus gastroenteritis from other causes in children.
- To evaluate the reliability of clinical signs for diagnosing rotavirus gastroenteritis.
- To investigate the association between upper respiratory illness and rotavirus gastroenteritis.
Main Methods:
- Prospective study of 128 children referred to a hospital with acute gastroenteritis.
- Clinical data including age, symptoms, and stool characteristics were collected.
- Rotavirus infection was confirmed through laboratory identification.
Main Results:
- Rotavirus was identified in 37% of patients.
- Rotavirus gastroenteritis cases were predominantly observed in children aged 5 months to 4 years and during winter.
- Clinical features included severe vomiting and absence of gross blood in stools, but these were not exclusive to rotavirus.
- Upper respiratory illness signs were present in similar proportions of rotavirus and non-rotavirus cases (36% vs. 35%).
Conclusions:
- Clinical signs alone are insufficient for a definitive diagnosis of rotavirus gastroenteritis.
- The high co-occurrence of upper respiratory illness symptoms questions the existence of a distinct rotavirus syndrome.
- Upper respiratory symptoms in rotavirus gastroenteritis cases may represent coincidental separate infections.
Abstract:
In a prospective study of children referred to hospital, rotavirus was identified in 37% of 128 patients with acute gastroenteritis. As compared with patients with non-rotavirus gastroenteritis, those with rotavirus gastroenteritis showed the following clinical characteristics: Age between 5 months and 4 years. Occurrence of the rotavirus infection almost exclusively during the winter season. Severe vomiting. Absence of gross blood in the stools. However, these signs did not form a safe basis for the clinical diagnosis of rotavirus gastroenteritis. One or more signs of upper respiratory illness were observed in 36% of the patients with rotavirus gastroenteritis and in 35% of those with non-rotavirus gastroenteritis. Consequently, the existence of a rotavirus syndrome is questioned. It is argued that upper respiratory illnesses in patients with rotavirus gastroenteritis could be due to a separate infection occurring coincidentally.
