Persistent post-enteritis diarrhoea in childhood: a prospective analysis of clinical features, predisposing factors
Insights
Persistent diarrhea affects 19% of children post-gastroenteritis. Risk factors include young age, low weight, Aboriginal ethnicity, and previous diarrhea, guiding management and prevention strategies.
Area of Science:
- Pediatric Gastroenterology
- Infectious Diseases
Background:
- Childhood gastroenteritis frequently leads to persistent diarrhea, a condition requiring further investigation.
- Understanding the determinants of persistent diarrhea is crucial for effective management and prevention in pediatric populations.
Purpose of the Study:
- To determine the incidence, pathophysiology, and clinical risk factors of persistent diarrhea (lasting >7 days) following childhood gastroenteritis.
- To identify key factors associated with the development of persistent diarrhea in children.
Main Methods:
- Prospective evaluation of 168 consecutive pediatric patients admitted with gastroenteritis.
- Computer-aided analysis to identify risk factors associated with persistent diarrhea.
Main Results:
- 19% (32/168) of children developed persistent diarrhea.
- Identifiable etiological factors included disaccharide/monosaccharide intolerance (31%), persistent pathogens (22%), and cow's milk protein intolerance.
- Risk factors for persistent diarrhea included young age, low weight percentile, Aboriginal ethnicity, history of previous diarrhea, delayed hospital admission, antibiotic/antidiarrheal use, and bacterial pathogens.
Conclusions:
- Persistent diarrhea after gastroenteritis is a significant complication in children.
- Early identification of at-risk children can guide targeted management and preventive strategies.
- Defined formula diets were often required for management.
Abstract:
To investigate the incidence, pathophysiology and clinic determinants of persistent diarrhoea (more than seven days) after childhood gastroenteritis, we prospectively evaluated 168 consecutive patients admitted to the Royal Children's Hospital, Brisbane, with gastroenteritis. Thirty-two children (19%) developed persistent diarrhoea; only two-thirds of them had an identifiable aetiological factor, including di- or monosaccharide intolerance (31%), persisting or suspected pathogen (22%) and cow's milk protein intolerance. Computer aided analysis of risk factors in the preceding enteritis showed this complication to be more frequent in young age groups (P less than 0.01) where the patient was less than 10th percentile for weight (P les than 0.02); in Aboriginals (P less than 0.01); where there was a history of previous diarrhoea (P less than 0.001), delayed hospital admission (P less than 0.001) and antibiotic/antidiarrhoeal usage (P less than 0.05); and where there was a bacterial pathogen (P less than 0.001). Severity and outcome were variable with most cases requiring a defined formula diet. These findings provide some insight into the problem of persisting diarrhoea after gastroenteritis, aid identification of at risk patients, and suggest guidelines for management and prevention.
