Lipid Profile in Pre-dialysis and Post-dialysis End Stage Renal Disease Patients: A Cross-Sectional Comparative Study in Lucknow, India

Background: Chronic kidney disease (CKD) patients are at elevated risk of cardiovascular diseases (CVD) due to altered lipid profiles. Dyslipidemia is maximal in end stage renal disease (ESRD) patients and there is insufficient data on the impact of hemodialysis on lipid profile. The present study was aimed to evaluate the effect of hemodialysis on lipid profile of CKD patients. Materials and Methods: This cross-sectional study was conducted on 50 CKD patients on hemodialysis from three randomly selected hospitals of Lucknow, Uttar Pradesh, India, between March - May 2021. Serum lipid profile was analysed before and after hemodialysis session by using an auto analyzer. The mean values of different lipid parameters before and after hemodialysis were calculated and the difference between them was analyzed by using paired t-test. A p-value of <0.05 was considered to be statistically significant. Results: In this study, very low density lipoprotein (VLDL) levels decreased significantly after hemodialysis. Total cholesterol (TC), low density lipoprotein (LDL) and triglyceride (TG) levels were also significantly lowered. High density lipoprotein (HDL) was the only lipoprotein that increased after dialysis although this increase was non-significant. Conclusion: Adequate dialysis and time bound monitoring of various components of lipid profile can help CKD patients by decreasing risks for cardiovascular complications.
