[Effect of high flux on lipid profile in haemodialysed patients].
BACKGROUND
Patients suffering from chronic kidney failure and patients on haemodialysis are characterized with numerous biochemical abnormalities, including hyperlipidemia. Hyperlipidemia is one of the risk factors that contribute to increased incidence of cardiovascular diseases among haemodialysed patients. The aim of our paper is to evaluate high flux effect in patients on haemodialysis.


METHODS
49 patients receiving dialysis treatment were included in this study (28 males and 21 females). 28 patients were on high flux (13M/15F) and 21 on low flux (8M/13F). All of them were followed up for one year. Lipid profile included testing of cholesterol, T6, VLDL, LDL, HDL, HDLC and atenogenic index.


RESULTS
Mean age of our dialysed population (N=49) is 56.8+/-10.1 years and mean dialysis duration is 3.7+/-1.26 years. Mean cholesterol level in patients on high flux was 5.42+/-1.26 at the beginning of the study. Female patients (N=15) showed significant decrease of cholesterol level (5.80+/-1.20), which after one year was 5.11+/-1.28, p<0.05. In 21 patients on low flux cholesterol was in normal range (4.72+/-0.94). Triglyceride (T6) level was significantly higher in female (3.13+/-1.33) on low flux than in males (2.35+/-1.25). Female patients have also shown a significant decrease of T6 level (2.31+/-1.33) at the end of the study. In 21 patients on low flux, mean values of T6 were 2.24+/-1.18 and there was no significant T6 decrease (2.51+/-1.20). HDL fraction of lipoproteins was lowered in both groups (0.188+/-0.074); HDL normalized in high flux group (0.2863+/-0.2394). Atenogenic index was significantly higher in low flux group (3.247+/-2.025) compared to high flux group.


CONCLUSIONS
Our dialyzed population showed an improvement of T6 level in patients that were on high flux. Female patients showed significant improvement in comparison to patients receiving conventional dialysis treatment. The mechanism responsible for different lipid profiles in dialyzed patients, with special emphasis on gender, should be explored further.
