Clinical features of viral and bacterial gastroenteritis in hospitalized children
Insights
Escherichia coli caused the most severe acute gastroenteritis in children, with bacterial infections often persisting longer than 10 days. Etiological agents were linked to specific symptoms, aiding in clinical prediction.
Area of Science:
- Pediatrics
- Infectious Diseases
- Microbiology
Background:
- Acute gastroenteritis is a common childhood illness.
- Identifying the etiological agent is crucial for effective treatment and management.
- Clinical presentation can vary significantly based on the causative pathogen.
Purpose of the Study:
- To investigate the clinical course and severity of acute gastroenteritis in hospitalized children.
- To determine the relationships between specific etiological agents and clinical symptoms.
- To explore the potential for predicting causative agents based on clinical presentation.
Main Methods:
- Studied 119 children hospitalized with acute gastroenteritis of known etiology.
- Utilized a disease severity scoring system.
- Analyzed etiological agents including Escherichia coli, Salmonella, human reovirus-like agent (HRLA), and Shigella.
- Calculated odds ratios to measure associations between agents and symptoms.
Main Results:
- Escherichia coli infections were associated with the most severe disease.
- Salmonella and Shigella infections presented with distinct clinical features compared to international reports.
- Fifty percent of patients recovered within 5 days; 20% with bacterial infections had symptoms for over 10 days.
- Significant associations were found between etiological agents and specific symptoms.
Conclusions:
- The severity of acute gastroenteritis in children varies by etiological agent.
- Clinical features can differ geographically for certain pathogens like Salmonella and Shigella.
- Odds ratios provide a basis for predicting the etiological agent of gastroenteritis in children based on clinical signs and symptoms.
Abstract:
The clinical course of 119 children, hospitalized with acute gastroenteritis of known etiology, was studied. The severity of disease was measured by a scoring system that showed that the disease caused by Escherichia coli was the most severe, followed in decreasing order by Salmonella, human reovirus-like agent (HRLA) and Shigella. The clinical features of salmonella and shigella infections differed from those reported in other countries. Fifty percent of all patients recovered after 5 days of treatment, but 20% of the patients with bacterial infections continued to have symptoms for 10 days or longer. The relationships between etiological agents and various symptoms were measured by odds ratios. These associations may provide a basis for clinical prediction of the etiological agent.
