BACKGROUND
The bacterial contamination of pancreatic necrosis in acute pancreatitis is supposed to occur through translocation of intestinal bacteria. Increased gut permeability may be the initial phenomenon in this process. To test the hypothesis that gut permeability is increased in acute pancreatitis a clinical study was made where gut absorption and permeability were assessed with multi-sugar probes in patients with acute pancreatitis within 2 days after admission to hospital and again after recovery of disease.
RESULTS
Twenty-three patients with acute pancreatitis and 20 healthy controls were studied. According to Atlanta classification, 15 patients had mild and 8 patients severe pancreatitis. Gut absorption, assessed as the 5-h urine excretion of L-rhamnose, D-xylose and 3-O-methylglucose, was decreased in patients with acute pancreatitis and more pronounced in patients with severe pancreatitis (L-rhamnose and D-xylose: P < 0.001; 3-O-methylglucose: P < 0.05). Gut permeability, assessed as the ratio of lactulose/L-rhamnose, was increased in severe pancreatitis (0.16 +/- 0.13, 0.07 +/- 0.03, 0.04 +/- 0.04; severe pancreatitis, mild pancreatitis, controls, respectively; P < 0.001 between three groups, P < 0.05 between pancreatitis groups).
CONCLUSIONS
Gut absorption capacity is decreased and gut permeability is increased in patients with acute pancreatitis. Patients with severe pancreatitis may be more exposed to impaired gut barrier function.
