Duodenal microflora: a prospective study in pediatric gastrointestinal disorders
The American Journal of Digestive Diseases
|August 1, 1975
Summary
Duodenal cultures in infants revealed that fecal-type bacteria, not oral-type, are linked to gastrointestinal issues like post-surgical diarrhea and monosaccharide intolerance. This finding highlights the importance of duodenal analysis in diagnosing specific pediatric digestive disorders.
Area of Science:
- Pediatric Gastroenterology
- Microbiology
- Infant Health
Background:
- The duodenal microflora in infants and children typically comprises oral-type microorganisms.
- Disruptions in the normal microflora composition can indicate underlying gastrointestinal pathology.
Purpose of the Study:
- To investigate the composition of duodenal microflora in pediatric patients with various gastrointestinal disorders.
- To determine the association between specific microflora types and conditions such as diarrhea and celiac disease.
Main Methods:
- Duodenal microflora cultures were performed on 96 infants and children.
- Microbiological analysis identified predominant microorganism types (oral vs. fecal).
- Correlation of microflora findings with clinical diagnoses was assessed.
Main Results:
- Fecal-type microflora was identified in infants with post-surgical diarrhea and temporary monosaccharide intolerance.
- Fecal-type microflora was also observed in some patients with protracted diarrhea of infancy and celiac disease.
- Oral-type microflora was predominant in healthy controls and those with nonspecific diarrhea.
Conclusions:
- Small-bowel contamination with fecal-type microorganisms is associated with impaired gastrointestinal motility and stasis.
- Duodenal culture is a crucial diagnostic tool for infants presenting with temporary monosaccharide intolerance.
- Duodenal culture can be beneficial in other pediatric gastrointestinal conditions involving disturbed motility.
