Fluorescein dilaurate test of exocrine pancreatic function in cystic fibrosis

Area of Science:

• Pediatric Gastroenterology
• Pancreatic Physiology
• Diagnostic Testing

Background:

• Cystic fibrosis (CF) frequently causes pancreatic exocrine insufficiency.
• Accurate assessment of exocrine pancreatic function is crucial for CF management.
• Non-invasive diagnostic methods are preferred for pediatric patients.

Purpose of the Study:

• To evaluate the efficacy of the fluorescein dilaurate test in diagnosing pancreatic exocrine insufficiency in children with CF.
• To determine if the fluorescein dilaurate test can differentiate CF patients with insufficiency from healthy controls.

Main Methods:

• The fluorescein dilaurate test was performed on 21 children diagnosed with cystic fibrosis and pancreatic exocrine insufficiency.
• A control group of 12 healthy siblings was included for comparison.
• The test measures exocrine pancreatic function non-invasively.

Main Results:

• The fluorescein dilaurate test demonstrated clear discrimination between the two groups.
• Patients with cystic fibrosis and severe pancreatic exocrine insufficiency showed significantly different results compared to healthy controls.

Conclusions:

• The fluorescein dilaurate test is a reliable, non-invasive tool for assessing exocrine pancreatic function in children with cystic fibrosis.
• This test effectively distinguishes pediatric CF patients with pancreatic insufficiency from healthy individuals, aiding in diagnosis and management.
