Fibrosing colonopathy

Fibrosing colonopathy is a disease that arises in people with cystic fibrosis treated with high doses of pancreatic enzyme supplements.[1][2] Symptoms are non-specific with abdominal pain, abdominal swelling, vomiting, and constipation.[1]

Fibrosing colonopathy
Other namesAbdominal pain, abdominal swelling, vomiting, constipation[1]
CausesHigh doses of pancreatic enzyme supplements[1]
Risk factorsYoung age, prior surgery of the intestines, certain medications including corticosteroids and H2 blockers[2]
Frequency>60 cases reported[2]

Risk factors include being young, prior surgery of the intestines, and the use of certain medications including corticosteroids and H2 blockers.[2] It may appear similar to distal intestinal obstruction syndrome or inflammatory colitis such as Crohn's disease.[1]

A maximum dose of 10,000 IU of lipase per kilogram per day is recommended for pancreatic enzyme supplementation to prevent this condition.[3] More than 60 cases have been described as of 1999.[2] The disease was suggested to be caused by methacrylic acid copolymer which is used as coating for delayed release of enzymes but there is no reliable evidence for that.[4]
