Abstract:
Acute pancreatitis (AP) in the setting of a normal serum amylase has been previously reported in the literature. Serum lipase on the other hand has a negative predictive value approaching 100% and therefore is an excellent test to rule out AP in the emergency department. The occurrence of AP with a normal lipase is extremely rare and has never been reported in the setting of drug-induced pancreatitis. Thiazide diuretics have been implicated as a cause of pancreatic injury via a number of proposed mechanisms. However, all such cases have been in the setting of elevated serum amylase or lipase. We report the first case of radiographically proven hydrochlorothiazide-induced pancreatitis with a normal lipase.

Acute Pancreatitis I: Introduction
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...
