Increase of long chain omega-3 fatty acids in the major serum lipid classes of patients with cystic fibrosis.
We studied the effects of supplementing patients with cystic fibrosis for 1 month with 3 g/day of a dietary supplement, containing 911 mg omega 3 fatty acids, on the fatty acid composition of serum cholesterol esters, free fatty acids, phospholipids and triglycerides. At the end of the supplementation period, the content of total omega 3 fatty acids was increased significantly in all lipid classes. The effect on individual omega 3 fatty acids depended on the fatty acid and lipid class studied, increased with the dose fed and decreased with the weight of the patient. One month after the end of the supplementation period, fatty acid levels had returned to pretreatment values. These results demonstrate that enrichment of serum lipid classes with omega 3 fatty acids is feasible in CF patients by dietary supplementation.
