Diagnosis of exocrine pancreatic insufficiency in cystic fibrosis by use of fluorescein dilaurate test

In the fluorescein dilaurate test fluorescein dilaurate is cleaved by the pancreas specific cholesterol ester hydrolase activity and the liberated fluorescein is absorbed and excreted in the urine. Fluorescein recovery is a reflection of exocrine pancreatic function. The test was evaluated in 14 pat...

description In the fluorescein dilaurate test fluorescein dilaurate is cleaved by the pancreas specific cholesterol ester hydrolase activity and the liberated fluorescein is absorbed and excreted in the urine. Fluorescein recovery is a reflection of exocrine pancreatic function. The test was evaluated in 14 patients with cystic fibrosis and 16 healthy volunteers. The test was well tolerated by patients, was easy to perform, and gave significantly lower values in the patients suffering from cystic fibrosis. The result of the pancreolauryl test was also correlated with the result of the faecal chymotrypsin test in 11 of the patients suffering from cystic fibrosis. A positive correlation was found between the two test results. The test is a practical and reliable index of pancreatic exocrine function and may have a useful role as a screening procedure.
