Chronic kidney disease progression in native and transplant kidneys.
OBJECTIVE
The present review addresses the recent literature demonstrating important differences in the rate of progression of kidney function decline between transplant recipients and patients with native kidney disease. It also highlights the need for prospective studies to determine the importance of nonimmune factors that are established risk factors for progression of native kidney disease in the transplant setting.


RESULTS
Transplant recipients establish modest levels of kidney function but have rates of kidney function decline that are slower than those in patients with native kidney disease. Continued improvements in long-term graft survival have not been achieved despite significant advances in immunosuppression. There is increasing observational evidence that nonimmune factors that play a causal role in progression of native kidney disease may also be important determinants of allograft decline. There are fundamental differences between transplant recipients and patients with native kidney disease that preclude extrapolation of evidence from native kidney disease to the transplant setting.


CONCLUSIONS
Transplant recipients are a unique group of chronic kidney disease patients. Prospective studies to determine the importance of nonimmune factors such as hypertension, proteinuria, dyslipidemia, diabetes, and anemia in the transplant setting are needed.
