Background: The Kidney Disease Quality Initiative (K/DOQI) of the National Kidney Foundation has published guidelines for the diagnosis and management of chronic kidney disease (CKD). Renal transplant recipients frequently have CKD and complications similar to native kidney disease patients. The purpose of the present study was to compare the management of CKD complications of transplant recipients and nontransplant patients.
Patients and methods: Eighty three renal transplant recipients with CKD stages 4T and 5T were compared with 83 nontransplant CKD patients matched by CKD stage.
Results: There were no differences between the groups in serum hemoglobin, prevalence of anemia, and percentage of patients treated with erythropoiesis-stimulating agents, but serum ferritin levels were higher among recipients (186.3 +/- 161.3 vs 119.1 +/- 113.4 ng/mL; P = .003). Mean blood pressure (BP) was similar in both groups but a systolic BP > 130 mm Hg was more frequent among recipients (83.3% vs 72.6%). More recipients were treated with either angiotensin-converting enzyme (ACE)-inhibitors or angiotensin receptor antagonist (43.3% vs 8.4%; P < .001). Low-density lipoprotein cholesterol was lower in recipients (108.9 +/- 30.3 vs 120.8 +/- 39.5 mg/dL; P = .033) and a higher percentage was on statin treatment (44.6% vs 28.9%; P = .053). Serum calcium was higher in transplant recipients (9.5 +/- 0.8 vs 8.9 +/- 0.7 mg/dL; P < .005) and phosphate was lower (3.9 +/- 0.9 vs 4.2 +/- 1.1; P = .043); there were no differences in intact parathyroid hormone blood levels.
Conclusions: The management of renal transplant recipients is no worse than that of nontransplant patients. However, in both populations, some parameters are far from the target recommended by the guidelines.
