Abstract:
A 23-year-old man experiencing three episodes of acute pancreatitis of undetermined etiology is described. Repeated questioning revealed that all three events had occurred after intake of the drug pyritinol. Controlled rechallenge with a single dose of the drug led to a fourth episode of acute pancreatitis. Skin testing was negative, but lymphocyte stimulation tests and double fluorescence analysis detected pyritinol-activated CD4 and CD8 lymphocytes. Together with the clinical observation that the intervals between drug intake and start of symptoms of acute pancreatitis became shorter with repeated exposure, the data are consistent with an immune-mediated origin of the pancreatitis. Pyritinol has to be added to the list of drugs capable of inducing acute 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...
