Weanling diarrhoea in The Gambia: implications of a jejunal intubation study
Insights
Changes in gut bacteria and bile salts in young Gambian children are linked to diarrhea and impaired growth during weaning. These issues may stem from a post-enteritis enteropathy exacerbated by traditional weaning foods.
Area of Science:
- Pediatrics
- Gastroenterology
- Microbiology
Background:
- Weaning age children in Gambia experience significant diarrheal morbidity and growth impairment.
- Abnormalities in jejunal (small intestine) flora and bile salt metabolism are observed in this age group.
Purpose of the Study:
- To investigate the relationship between jejunal flora, bile salt metabolism, and diarrheal morbidity in Gambian village children during the weaning period.
Main Methods:
- The study focused on Gambian village children in the weanling age group.
- Observations included jejunal flora and bile salt metabolism.
Main Results:
- Abnormalities in jejunal flora and bile salt metabolism were most pronounced in the youngest weanling children.
- These changes correlate with increased diarrheal morbidity and growth impairment following the introduction of supplementary foods.
- Small bowel colonization was not identified as a direct cause.
Conclusions:
- The observed abnormalities may indicate a post-enteritis enteropathy, a condition potentially responsible for the weanling diarrhea syndrome.
- Traditional weaning foods are speculated to cause and perpetuate this enteropathy.
Abstract:
Abnormalities in jejunal flora and bile salt metabolism were most marked in the youngest members of a group of Gambian village children in the weanling age group. These may be linked with the profound change in diarrhoeal morbidity, particularly diarrhoea-induced growth impairment, which occurs as soon as breast-fed infants are regularly supplemented. The pathogenesis of these changes is not understand. The presence of small bowel colonization did not appear to be a causal factor but, it is speculated, its appearance may mark the development of a post-enteritis enteropathy which is responsible for the weanling diarrhoea syndrome and which is caused and perpetuated by traditional weaning foods.
