Effects of cod liver oil on platelets and coagulation in familial hypercholesterolemia (type IIa).
Patients with familial hypercholesterolemia (type IIa) were given 30 ml cod liver oil (CLO) as dietary supplement daily for 6 weeks. The effects on platelets, bleeding time, coagulation and blood and platelet lipids were examined. The major findings were a reduced collagen-induced platelet aggregation and a decrease in thrombin-stimulated thromboxane B2 generation in platelets in vitro. The primary bleeding time was not significantly prolonged. Statistically significant increase in eicosapentaenoic acid/arachidonic acid ratios in the main platelet phospholipids were also observed. These changes did not correlate with any of the changes in platelet behavior observed after CLO intake. The serum total and HDL cholesterol and triglycerides were not altered during the trial.
