title: [Intra-digestive fermentation in intestinal malabsorption syndromes: relations with elevated serum activity of gamma-glutamyl-transpeptidase].
abstract: The aim of this prospective study was to examine the relationship between gastrointestinal ethanol production ("Mei-Tei-Sho" syndrome described in Japan) and biological liver dysfunction associated with intestinal malabsorption syndromes.
  
  
  METHODS
  Sixty-five patients with malabsorption-diarrhea underwent 98 simultaneous measurements of plasma gamma-glutamyl-transpeptidase and of faecal ethanol concentrations; in 5 cases, ethanolemia and faecal ethanol concentrations were measured after a 250 g rice-meal; in 1, ethanol concentration was measured in a sample of caecal liquid in hours following local instillation of fructose (40 g).
  
  
  RESULTS
  Faecal ethanol was detected at least once in 60/65 patients (74/98 measurements, maximum 3.50 g*L-1), more often (98.0%, P < 0.001) in 51 patients with gamma-glutamyl-transpeptidase above 38 IU/L. Eating rice increased the faecal ethanol concentration in 5 patients, 2 of whom had measurable ethanolemia (0.20 and 0.47 g*L-1). Ileo-caecal ethanol concentration following local fructose instillation was 11.8 g*L-1.
  
  
  CONCLUSIONS
  Endogenous gastrointestinal ethanol production contributes to elevated gamma-glutamyl-transpeptidase activity observed during malabsorption syndromes.
