title: Serum apolipoprotein A-I in alcoholic patients with chronic calcifying pancreatitis.
abstract: Serum apolipoprotein A-I measurement was compared in alcoholic patients according to presence or absence of chronic pancreatitis and liver fibrosis. Among alcoholic patients without liver disease, apolipoprotein A-I was significantly lower in patients with chronic pancreatitis (157 +/- 70 mg/dl) than in patients without pancreatitis (209 +/- 74 mg/dl, p less than 0.001). In cirrhotic patients, apolipoprotein A-I was lower in patients with chronic pancreatitis (82 +/- 35 mg/dl) than in patients without pancreatitis (102 +/- 45 mg/dl), but this difference was not significant. The decrease of serum apolipoprotein A-I was independent of nutritional parameters whether or not there was cirrhosis. Immunohistochemical study of pancreatic samples with chronic pancreatitis showed that apolipoprotein A-I was located in the pancreatic fibrosis whereas lobules were unstained. This study suggests that apolipoprotein A-I is trapped by the pancreatic extracellular matrix and that this sequestration might explain, in part, the decrease of the serum apolipoprotein A-I.
