Background: Kidney transplantation is still the treatment of choice for end-stage renal disease, therefore it is important to establish all modifiable risk factors for initiation of renal dysfunction.
Material and Methods: We enrolled 73 renal transplant recipients, who were more than 12 months post-renal transplant surgery, had a stable graft function, had no clinically present cardiovascular disease, and were on standard immunosuppressive therapy. The concentrations of intracellular adhesion molecule-1 (ICAM-1), vascular adhesion molecule-1 (VCAM-1), CRP, lipids, and lipoproteins were measured. We used logistic regression to calculate non-adjusted, age, and multivariable-adjusted ORs and 95% confidence intervals for glomerular filtration rate, GFR <60 ml/min/1.73 m2.
Results: Non-adjusted OR showed that there was a significant risk of reduced GFR in patients with total cholesterol higher than 5.19 mmol/L, LDL cholesterol ≥4.1 mmol/L, non-HDL ≥4.2 mmol/L, and higher VCAM-1 concentration. After adjustment for age and in multivariable model, OR showed a significant risk for reduced GFR in patients with total cholesterol ≥5.2 mmol/L, LDL ≥4.1 mmol/L, non-HDL ≥4.2 mmol/L, and higher VCAM-1 concentration. HDL, triglycerides, CRP, and lipoprotein ratios did not have any significance as predictors of renal dysfunction. There were no differences in all evaluated parameters between groups in regard to immunosuppressive therapy.
Conclusions: Total cholesterol, LDL, non-HDL, and VCAM-1 are strong and independent predictors of renal dysfunction in stable renal transplant recipients. In contrast, HDL, CRP, triglycerides, and ICAM-1 did not seem to have any impact on renal dysfunction.
