Hypertriglyceridaemia associated with low HDL-concentrations is considered an independent risk factor of ischaemic heart disease. The drug of choice in this disorder is nicotinic acid. The aim of the presented work was to compare the hypolipidaemic effect of fish oils rich in omega-3 fatty acids (Activepa 30-TGR, Hydromartens, Norway) with a nicotinic acid derivative, acipimox (Olbetam, Farmitalia Carlo Erba, Italy). The preparations were administered for a three-week period to two groups of patients with hypertriglyceridaemia and low HDL cholesterol levels. The groups had comparable body weights and baseline parameters of lipid metabolism. In the group treated with Olbetam (750 mg/day), 17x hyperlipoproteinaemia type IV and 6x IIB) after treatment significant changes of the following parameters were recorded: triglycerides (-18%; P < 0.001), HDL cholesterol (+19%; P < 0.01), HDL2 and HDL3 cholesterol (+33%; +14%; P < 0.001, P < 0.01), apo B (+25%; P < 0.01), apo A-I (+7%; P < 0.01), ratio of apoB/A-I (+17%; P < 0.01). Furthermore, there was s drop of the atherogenic index (total cholesterol/HDL cholesterol) by 22% (P < 0.001). In the group of subjects (17x type IV and 8x type IIB) whose diet was enriched with omega-3 fatty acids (3.5 g/day), the following parameters changed significantly: triglycerides (-44%; P < 0.001), the atherogenic index (-23%; P < 0.001), HDL cholesterol (+11%, P < 0.01), HDL2 and HDL3 cholesterol (+13%, +17%; P < 0.01, P < 0.05). Changes of apo B, apo A-I concentrations and their ratios were not significant. Comparison of the effect of the two preparations on the investigated parameters revealed a more marked rise of the HDL cholesterol (P < 0.05), apo B (P < 0.01) concentrations and the apo B/-A-I ratio (P < 0.05) during Olbetam treatment. As to the action of the two preparations on further investigated parameters (total and LDL-cholesterol), no significant differences found. The assembled results indicate that enrichment of the diet with fish oil rich in omega-3 fatty acids has a hypolipidaemic effect comparable to acipimox. It is thus feasible to use fish oils as a drug of first choice in the treatment of hypertriglyceridaemia associated with a reduction of HDL cholesterol concentration.
