Effects of cod liver oil on platelets and coagulation in familial hypercholesterolemia (type IIa)
Insights
Cod liver oil (CLO) supplementation in familial hypercholesterolemia patients reduced platelet aggregation and thromboxane generation. However, it did not significantly alter bleeding time or serum lipid levels.
Area of Science:
- Cardiology
- Nutrition Science
- Biochemistry
Background:
- Familial hypercholesterolemia (FH) is a genetic disorder characterized by high cholesterol levels.
- Platelet aggregation plays a role in cardiovascular disease development.
- Dietary interventions are explored to manage FH and related cardiovascular risks.
Purpose of the Study:
- To investigate the effects of cod liver oil (CLO) supplementation on platelet function, coagulation, and blood lipids in patients with FH.
- To assess changes in platelet aggregation, bleeding time, and lipid profiles after CLO intake.
Main Methods:
- A 6-week trial involving FH patients receiving 30 ml of CLO daily.
- Evaluation of collagen-induced platelet aggregation and thrombin-stimulated thromboxane B2 generation.
- Measurement of bleeding time, platelet phospholipid fatty acid composition, and serum lipid levels.
Main Results:
- CLO significantly reduced collagen-induced platelet aggregation and thrombin-stimulated thromboxane B2 generation.
- Increased eicosapentaenoic acid/arachidonic acid ratios were observed in platelet phospholipids.
- No significant prolongation of primary bleeding time or alterations in serum total cholesterol, HDL cholesterol, and triglycerides were noted.
Conclusions:
- Cod liver oil supplementation may modulate platelet activity in FH patients by altering phospholipid composition.
- These anti-aggregatory effects did not translate to prolonged bleeding times or improved overall lipid profiles in this study.
- Further research is needed to understand the clinical implications of CLO on cardiovascular risk in FH.
Abstract:
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.
