Abstract:
Infectious diarrhoea are common causes of morbility in children. Although viral agents are responsible for the majority of cases of acute diarrhoea during infancy, bacterial infections are also well recognized as causes of them. 256 patients with diarrhoea due to a bacterial pathogen were studied to determine the importance of different epidemiologic factors. The study group comprised 151 boys (59%) and 105 girls (41%) aged between first month and 14 years. Family history of acute diarrhoea was found in 15% of children. 63,7% of them were hospitalized by the severity of clinical features. 32% of cases were detected in summer. Salmonella entérica was isolated in 45% of stool samples and Campylobacter spp in 33,2%. Clinical evolution of diarrhoea differentiated the patients into three groups: acute diarrhoea (95,7%), prolonged diarrhoea (3,1%) and chronic diarrhoea (1,1%).
Insights
Bacterial infections cause significant infectious diarrhea in children, with Salmonella enterica and Campylobacter spp. being the most common pathogens. Many cases required hospitalization due to severe symptoms.
Area of Science:
- Pediatrics
- Infectious Diseases
- Microbiology
Context:
- Infectious diarrhea is a common pediatric illness.
- While viral agents are frequent, bacterial pathogens also contribute significantly to morbidity.
- Understanding epidemiologic factors is crucial for managing pediatric diarrhea.
Purpose:
- To investigate the epidemiologic factors associated with bacterial infectious diarrhea in children.
- To identify the predominant bacterial pathogens causing diarrhea in the study population.
- To analyze the clinical presentation and evolution of bacterial diarrhea.
Summary:
- A study of 256 children with bacterial diarrhea revealed Salmonella enterica (45%) and Campylobacter spp. (33.2%) as primary causative agents.
- The majority of cases (63.7%) required hospitalization due to severe clinical features.
- Diarrhea was predominantly acute (95.7%), with a smaller proportion being prolonged (3.1%) or chronic (1.1%).
- Summer seasonality was noted, with 32% of cases occurring during this period.
Impact:
- Highlights the significant role of bacterial pathogens in pediatric infectious diarrhea.
- Provides data on common bacterial culprits and their prevalence.
- Emphasizes the need for timely diagnosis and management of severe bacterial diarrhea in children.
- Informs public health strategies for prevention and control of pediatric diarrheal diseases.
