摘要：Chronically hemodialyzed (HD) patients frequently suffer from quantitative and even more often qualitative serum lipids disorders. Mostly they have increased triglycerides and VLDL-cholesterol, slightly increased or normal total and LDL-cholesterol and decreased HDL-cholesterol concentrations. The study compared lipid profile between two groups of chronic HD patients coming from regionally distinct areas, the continental and the maritime one. The aim was to examine the hypothetic influence of their different dietary habits on lipid profile. The study included 72 patients from continental region (39 men) and 50 from maritime part of the country (30 men). Patients suffering from diabetes mellitus, hypothyroidism, liver disease, alcoholics as well as sevelamer treated patients were not included. Prior to a HD session the patients were determined fasting total cholesterol, triglycerides, HDL- and LDL-cholesterol, total proteins, albumins and C-reactive protein serum concentrations. All patients were undergoing bicarbonate hemodialysis with polysulphone dialysers of low permeability. The continental group of patients were somewhat older, undergoing HD for longer period of time, of lower height, greater weight, greater body mass index, higher total (4.70±0.91: 4.42±1.02 mmol/L), and LDL-cholesterol (2.78±0.74:2.66±0.75 mmol/L) concentrations, while lower triglycerides (1.72±0.84:1.81±0.83 mmol/L) and HDL-cholesterol (1.13±0.42:1.16±0.54 mmol/L). However, all the differences were without statistical significance. Chi-square test showed that the continental group of patients consumed more often pork, bacon, smoked and cured meats, margarine, butter, walnuts, almonds, garlic, cream and full-fat cheese than fish. They prepare food more often with lard and sunflower oil. Almost every fourth continental patient received statins, while only every 25th in the maritime group of patients. There were not any statistically significant Chi-square values for differences in frequencies of patients with total cholesterol greater than 5.2 mmol/L, triglycerides above 1.6 mmol/L, HDL-cholesterol less than 1.1 mmol/L, LDL-cholesterol greater than 2.6 mmol/L, obesity and malnutrition between the two groups. Based on the results of this study we have concluded that diet has significant influence on lipid profile of HD patients. Even though the continental and the maritime groups of patients differed significantly in diet, they were similar in plasmatic lipoprotein concentrations. However, this similarity was ascribed only to statin treatment, which was more frequent in the continental group of patients. The influence of ESRD and HD as a method of renal replacement therapy on lipid profile was not more dominant than diet.
