Cystic Fibrosis Clinical Trial
Official title:
Role of DHA Monoglyceride (MAG-DHA) in the Resolution of Pulmonary Inflammation of Patients With Cystic Fibrosis.
Monoglyceride of DHA (DHA-MAG) is a lipid compound for which intestinal absorption would
increase the ratio DHA / arachidonic acid (AA) and promote the synthesis of specific
metabolites involved in the resolution of inflammation.
The PREMDIC project, initiated at the Centre Hospitalier Universitaire de Sherbrooke, is a
randomized double-blind study for people with cystic fibrosis (CF) and aims to evaluate
whether daily supplementation monoglyceride of DHA (a fatty acid omega-3 family) will reduce
lung inflammation and improve pulmonary function.
The goal of the study is:
To investigate the efficacity of oral administration of MAG-DHA to increase DHA
bioavailability and reduce lung inflammation of patients with cystic fibrosis
The specific objectives of the project are :
- Determine the effect of MAG-DHA on lipid membranes of the blood mononuclear cells.
- Evaluate the effect of MAG-DHA on lung inflammation (determination of Human leukocyte
elastase and alpha1 antitrypsin complexes : pHLE).
For this study, 20 cystic fibrosis patients are recruited. Patients are divided into 2 groups
of 10 and received a daily dose equivalent to 3 g of placebo (sunflower oil) or MAG-DHA.
The project takes place over a period of 3 months and patients must travel to the research
center for a total of five visits including recruitment.
For the 2 groups, DHA ratio / AA is measured in membranes of mononuclear cells. Forced
expiratory volume in 1 second (FEV1) is determined and pHLE complexes are detected in plasma
as a marker of inflammation.
