Abstract:
Pancreatic exocrine insufficiency in cystic fibrosis is genetically determined and generally felt to be irreversible. However, recent studies in young children started on cystic fibrosis transmembrane conductance regulator (CFTR) modulators have suggested improvement of pancreatic functioning over time. Here, we present the case of a 10-year-old child with pancreatic exocrine insufficiency since birth who regained pancreatic functioning after 4 years on the CFTR corrector drug, ivacaftor.

Pancreatic Juice and Secretion
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...
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...
