Correlation Between Homocysteine and Lipid Parameters in Patients with End-Stage Renal Disease
Introduction. Chronic kidney insufficiency presents a progressive decline in renal function. Long-term hemodialysis treatments lead to biochemical parameter imbalances like an altered level of homocysteine (Hcy). Hcy can contribute to oxidative stress and endothelial damage, which promotes the accumulation of low-density lipoprotein (LDL) cholesterol and the development of atherosclerosis. It can also affect lipoprotein metabolism and trigger inflammatory processes that alter the lipid profile, especially increasing triglycerides and lowering high-density lipoprotein (HDL) cholesterol. Methods. This cross-sectional, clinical and descriptive-analytical study included 83 patients, 40 patients on hemodialysis, and 43 subjects in healthy control group. Results. The hemodialysis group had significantly higher Hcy values compared to the control group of seemingly healthy subjects (p<0.05). The control group had significantly higher values of total cholesterol, LDL and very low-density lipoprotein (VLDL) compared to the hemodialysis patients (p<0.05). There was non significant correlation between Hcy and lipid parameters in the hemodialysis group, neither in the control group. Conclusion. Patients undergoing hemodialysis had significantly higher total homocysteine levels compared to the control group. However, total homocysteine did not demonstrate an association with lipid status parameters in either the hemodialysis patients or the healthy subjects.
