Dyslipidemia and oxidative stress are causative factors for atherosclerosis changes in hemodialysis patients

Abstract

Background: Cardiovascular disease is one of the leading cause of death in chronic kidney disease. The increased cardiovascular mortality observed in all stages of Chronic kidney disease patients. In hemodialysis cardiovascular mortality is more than 60%. In hemodialysis dyslipidemia contribute for the triggering of atherosclerosis. Endothelial dysfunction and oxidative stress are serves as main precursor for the progression of atherosclerosis. So the present study was aimed at studying lipid profile and oxidative stress in hemodialysis patients.Methods: A cross sectional study carried out over a 2 year period in Department Nephrology and General Medicine OPD, MIMS, Vizianagaram, Andhra Pradesh, India. A total of 60 hemodialysis patients are included. In all the participants Lipid profile, SOD, MDA and Serum Nitrate was measured. Results: There is a significantly increased levels of serum triglycerides and VLDL in hemodialysis patients when compared with Control. The HDL-C was significant Lower in hemodialysis patients when compared with control. The serum total cholesterol and LDL-C not shown any significant change. The Serum MDA and Serum Nitrate was significantly higher in hemodialysis patients compared with Control and it is statistically significant (p<0.001). Whereas the serum SOD value was significantly decreased in hemodialysis patients when compared with control and it is statistically significant (p<0.001).Conclusion: Present study finding suggested that the incidence of atherosclerosis changes are higher in hemodialysis patients. Early detection and correction of atherosclerosis changes can help us to reducing the deleterious effects.

Oxidative stress as the bridge between dyslipidemia and peritoneal ultrafiltration failure: A bi-center cross-sectional cohort study

“…However, despite this recognition, the association between dyslipidemia and oxidative stress in the context of PD remains unexplored [7]. Most studies investigating the interplay between dyslipidemia and oxidative stress have predominantly focused on the broader population of individuals with CKD [12,13] or those undergoing hemodialysis [9,18], leaving a substantial knowledge gap in patients on PD.…”
