Abstract: OBJECTIVE: To systemically review and analyze the effect of n-3 polyunsaturated fatty acid (PUFA) consumption on plasma lipids and lipoproteins in patients with end-stage renal disease. DESIGN: Systemic review, with meta-analysis of randomized controlled clinical trials. METHODS: We performed a systemic review and meta-analysis of the lipid-modulating effects of n-3 PUFAs by combining evidences from 10 randomized controlled trials including 557 patients with end-stage renal disease. RESULTS: Pooled analysis revealed that n-3 PUFA intake significantly reduced serum triglyceride levels by -0.78 mmol/L (95% confidence interval: -1.12 to -0.44 mmol/L, P < .0001). Consumption of n-3 PUFAs also reduced the plasma low-density lipoprotein cholesterol levels by -0.09 mmol/L and elevated plasma high-density lipoprotein cholesterol levels by -0.25 mmol/L, but these changes were not statistically significant. Plasma levels of total cholesterols were elevated in both n-3 PUFA and control groups, with a lesser increase in the n-3 PUFA group, without statistical significance. Metaregression showed no correlation between the amounts or duration of n-3 PUFA intake and their lipid-modulating effects. CONCLUSIONS: In our meta-analysis, n-3 PUFA consumption significantly lowered the serum triglyceride levels. No significant changes were found on the degrees of low-density lipoprotein cholesterol reduction and total cholesterol or high-density lipoprotein cholesterol elevation effects.[Abstract] [Full Text] [Related] [New Search]
