Background/Aims:
The aim of the study was to evaluate fasting plasma level of islet amyloid polypeptide in patients with chronic alcoholic pancreatitis and its possible correlation with the extent of pancreatic structural damage as well as endocrine function.
Methodology:
Fifty-seven non-obese patients with chronic alcoholic pancreatitis and 20 healthy subjects were studied. In all subjects RIA plasma fasting amylin, insulin and C-peptide estimation were performed.
Results:
In patients with chronic alcoholic pancreatitis, particularly in those with advanced pancreatic structural damage in imaging techniques, fasting plasma amylin levels were significantly higher (p < 0.01) than in controls. Within chronic alcoholic pancreatitis group the highest plasma islet amyloid polypeptide values of 139.0 +/- 8.7 pg/100 microL were found in patients with glucose impaired tolerance, which was significantly higher (p < 0.01) than in patients with normal endocrine pancreatic function, non-insulin requiring and insulin requiring diabetes where the respective values were: 69.1 +/- 9.2 pg/100 microL, 75.5 +/- 5.2 pg/100 microL and 84.7 +/- 12.5 pg/100 microL.
Conclusions:
Those findings suggest that islet amyloid polypeptide may play a role in the pathogenesis of chronic alcoholic pancreatitis. In addition increased plasma islet amyloid polypeptide level may prove useful as an indicator of an early phase of pancreatic endocrine function impairment and severe parenchymal damage in chronic pancreatitis.

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:
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...
