title: Effect of an alpha-glucosidase inhibitor on intestinal fermentation and faecal lipids in diabetic patients.
abstract: Eight non-insulin-dependent diabetes mellitus patients, in whom oral hypoglycaemic agents were not effective, were treated with an alpha-glucosidase inhibitor, AO-128 (0.9 mg/day) for 6 months. After 6 months of treatment there was a statistically significant decrease in the blood glucose level 1 and 2 h postprandially. The 2 h blood glucose level was also significantly reduced after 2 months' treatment. The insulin and HbA1c levels after 2 and 6 months' treatment were lower than those before administration. Faecal weight, the frequency of bowel movements, the ratio of hydroxy fatty acids to total fatty acids, and faecal short-chain carboxylic acid content were all increased significantly during treatment. The initially hard stools became normal or soft, although no actual diarrhoea developed. Both faecal bile-acid excretion and the ratio of primary bile acids to total bile acids were increased significantly after 2 months, but they showed some recovery towards the pretreatment levels after 6 months' treatment. There was no distinct change in neutral sterol and fatty acid excretion. Breath hydrogen excretion showed a slight increase after treatment. These results suggest that intestinal fermentation was promoted and the intestinal transit time was shortened by AO-128 administration.
