Objectives:
Alcohol abuse causes pancreatic damage in humans. However, only 5% of alcoholic patients have a clinical manifestation of pancreatitis, and the genetic predisposition of alcohol-associated pancreatitis remains elusive. Nonoxidative metabolites of ethanol, fatty acid ethyl esters (FAEEs), might play an important role in pancreatic damage. Carboxylester lipase (CEL) has been known to catalyze FAEE synthesis from fatty acids and ethanol.
Methods:
The variable number of tandem repeat (VNTR) polymorphism in the coding region of the CEL gene was studied in patients with alcoholic pancreatitis (n = 100), in alcoholics without pancreatitis (n = 52), in patients with nonalcoholic pancreatitis (n = 50), in hyperlipidemia patients (n = 96), and control subjects (n = 435).
Results:
The frequency of the NN-type (wild-type) gene was significantly decreased in patients with alcoholic pancreatitis than in other groups. The frequency of subjects who had the L allele in patients with alcoholic pancreatitis was significantly higher than in other groups. The distribution of the CEL gene polymorphism was not different among the control subjects, alcoholics without pancreatitis, patients with nonalcoholic pancreatitis, and patients with hyperlipidemia.
Conclusions:
The CEL gene polymorphism, especially an increase in the frequency of the L allele, was found to be associated with alcohol-induced pancreatitis.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
