    Abstract:
    Cirrhotic patients often present muscle and adipose tissue depletion as well as reduced visceral protein concentration. Impaired absorption of nutrients may contribute to this altered nutritional status. To verify this hypothesis fecal fat excretion, intestinal mucosal function evaluated by means of the combined sugar oral load test, and intestinal clearance of alpha-1-Antirypsin were studied in 25 cirrhotic patients with clinical and biochemical signs of liver insufficiency and with portal hypertension. About 50% of the patients showed clinical evidence of malnutrition. Three of the 12 well-nourished, and 8 of the 13 malnourished patients presented significant steatorrhoea. Cirrhotics showed no impairment in mediated malabsorption and in passive permeability, as plasma D-xylose/3-O-methyl-glucose concentration and urinary lactulose/L-rhamnose excretion ratios were within the normal range. An increased value of alpha-1-Antitrypsin clearance was found only in two patients. These findings indicate that fat malabsorption is frequent in cirrhotic patients, particularly when malnourished, and does not depend on the presence of mucosal intestinal damage.
