title: Evaluation of Serum Oxidized Low-Density Lipoprotein in Renal Transplant Recipients and Hemodialysis Patients and Relation With Involved Variables.
abstract: OBJECTIVE
  Disturbances in metabolism of lipo-proteins and oxidative modification of low-density lipoprotein contribute to cardiovascular disease and development of oxidative stress in patients under renal replacement therapy (hemodialysis and renal transplant). This study was designed to compare oxidized low-density lipoprotein levels and lipid profiles in renal transplant recipients and hemo-dialysis patients.
  
  
  METHODS
  We investigated the concentration of oxidized low-density lipoprotein in hemodialysis (n = 38) and renal transplant (n = 59) patients who had no active inflammatory disease, liver disease, or malignancy, and results were compared to a control group (n = 30).
  
  
  RESULTS
  Renal transplant recipients had hypercholesterolemia, hypertriglyceridemia, and increased oxidized low-density lipoprotein levels (P = .019) compared with the control group. Hemodialysis patients had moderate hypertriglyceridemia (not significant), hypercholesterolemia, decrease in high-density lipoprotein, and increase in oxidized low-density lipoprotein levels (P < .0001) compared with the control group. In the renal transplant group, oxidized low-density lipoprotein level had a negative correlation with the duration after transplant (r = -0.407; P = .026), positive association with cyclosporine level (r = 0.288; P = .04), and negative correlation with high-density lipoprotein level (r = -.30; P = .05); oxidized low-density lipo-protein/high-density lipoprotein ratio also had a positive correlation with cyclosporine level (r = 0.309; P = .027) and negative correlation with high-density lipoprotein level (r = -0.72; P < .001) in the renal transplant group and high-density lipoprotein in the hemodialysis group (r = -0.87; P < .001). Multiple stepwise regression analyses showed that oxidized low-density lipoprotein only was associated with cyclosporine level (R2 = 0.155; β=0.393; P = .024).
  
  
  CONCLUSIONS
  History of cardiovascular disease is the most important factor associated with end-stage renal disease, and high oxidized low-density lipoprotein level, oxidized low-density lipo-protein/high-density lipoprotein ratio, and high-density lipoprotein level may affect cardiovascular disease.
