Achtergrond van het onderzoek
The fecal fat balance is the current gold standard for evaluating fat malabsorption in CF patients. However there is a need for a simpler, sensitive and less restraining test to determine fat absorption in CF patients. More insight in the relative contribution of lipolysis and intestinal malabsorption of free fatty acids to fat malabsorption in CF patients would give way for a more directed therapeutic approach.
The aim if the this study is to proof that the double labeled triglyceride and free fatty acid fat absorption test is as effective as the fecal fat balance as a quantitative diagnostic test for intestinal fat absorption in CF patients.
In the study we use triglyceride and free fatty acid both labeled with a different stable isotope. The double labeled triglyceride and free fatty acid fat absorption test is based principle of simultaneous admission of both the labeled triglyceride and labeled free fatty acids. The resulting appearance curve in the plasma determines the absorption of the separate components and is an indication for intestinal fat absorption.
Doel van het onderzoek
The double labeled triglyceride and free fatty acid fat absorption test is as effective as the fecal fat balance as a quantitative diagnostic test for intestinal fat absorption in CF patients.
