Faecal methylamine in normal and uraemic subjects
Clinical Science (London, England : 1979)
|May 1, 1979
Summary
Methylamine was identified in fecal dialysate from both normal and uremic individuals. Uremic subjects showed higher methylamine levels, correlating with kidney function impairment.
Area of Science:
- Biochemistry
- Nephrology
- Gastroenterology
Background:
- Uremia is associated with altered metabolite profiles.
- Fecal metabolites may reflect systemic metabolic changes.
Purpose of the Study:
- To identify ninhydrin-reacting substances in fecal dialysate.
- To investigate methylamine levels in normal versus uremic subjects.
Main Methods:
- Ion-exchange chromatography was used to analyze fecal dialysate.
- In vivo samples were obtained from normal and uremic subjects.
Main Results:
- Methylamine was isolated and identified as a key ninhydrin-reacting substance.
- Fecal dialysate methylamine concentrations were significantly higher in uremic patients (P < 0.05).
- No significant difference in methylamine levels was observed between fecal dialysate and centrifugate.
Conclusions:
- Methylamine is present in human fecal dialysate.
- Elevated fecal methylamine may serve as a biomarker for renal impairment in uremia.
