Abstract
Chronic alcohol intake interferes especially with the two main pathways regulating exocrine pancreatic secretion: the cholinergic and the pancreozymin pathway. Recently, a new theory of the pathogenesis of alcoholic pancreatitis was proposed emphasizing disordered agonist-receptor interaction at the level of pancreatic acinar cells. Accordingly, alcohol-induced alterations in the control of exocrine pancreatic secretion result in hyperstimulation of pancreatic acinar cells and their muscarinic receptors, mimicing the mechanism of acute pancreatitis caused by scorpion sting, intoxication with an anti-acetylcholinesterase-containing insecticide or supramaximal doses of secretagogues. The present review emphasizes the role of these alcohol-induced secretory alterations in the pathogenesis of alcoholic pancreatitis.
