In children, what condition is commonly associated with chronic pancreatitis?

Chronic pancreatitis in children is most commonly associated with cystic fibrosis, a genetic disorder that affects the exocrine glands, including those of the pancreas. In cystic fibrosis, the mutation in the CFTR gene leads to thick, viscous secretions that can block pancreatic ducts, preventing the normal flow of digestive enzymes. This obstruction can cause damage to the pancreatic tissue over time, leading to chronic pancreatitis.

In contrast, the other conditions listed are more commonly associated with chronic pancreatitis in adults rather than in children. Gallstones, while they can cause pancreatitis, particularly in adults, are not a prevalent cause in the pediatric population. Alcohol consumption is a significant risk factor for chronic pancreatitis in adults but is not typically a factor in children. Obstructive jaundice can result from a variety of causes, but it does not have a direct link to chronic pancreatitis in children as cystic fibrosis does. Thus, cystic fibrosis stands out as the primary condition associated with chronic pancreatitis in the pediatric age group.
