Hemodialysis (HD) patients have a high incidence of hyperlipidemia. Hypertriglyceridemia is the most frequent abnormality encountered. It results mainly from a defect in the degradation of triglycerides. The aim of this study was to evaluate the efficacy of a fish oil (Max-EPA) rich in polyunsaturated fatty acids (PUFA), such as eicosapantenoic acid (EPA), on lipid abnormalities of hemodialysis patients. Thirteen hyperlipidemic HD patients were investigated (7 males, 6 females; mean age 57 years; mean duration of HD 72 months). None were diabetic or treated with antihypertensive drugs. All patients had hypertriglyceridemia (greater than 200 mg/dl) and an increase (greater than 1) in the ratio of serum apolipoprotein B to serum apolipoprotein A1 (ApoB/ApoA1). They received for one month, 6 g/day of Max-EPA providing 1 g of EPA. After treatment, serum triglyceride levels fell by 38% from 231 +/- 40 (SD) mg/dl to 140 +/- 38 mg/dl (P less than 0.01). Total cholesterol did not change significantly (before therapy 241 +/- 33 mg/dl, after therapy 249 +/- 38 mg/dl). Apolipoprotein A1 levels (116 +/- 17 mg/dl) were not modified after therapy, 117 +/- 11 mg/dl. Apolipoprotein B decreased significantly from 182 +/- 26 mg/dl to 150 +/- 21 mg/dl after treatment (P less than 0.01). The ApoB/ApoA1 ratio showed a significant decrease from 1.56 +/- 0.26 to 1.3 +/- 0.16 after therapy (P less than 0.01). Also, the greatest reductions were found in the patients who had both the highest serum triglyceride levels and the highest ApoB/ApoA1 ratios. No side effects were observed.(ABSTRACT TRUNCATED AT 250 WORDS).
