Eligibility Criteria

Male or female participants from 18 years up to 75 years old.

Inclusion Criteria: 1. Patients with Stage 3 or 4 chronic kidney disease as measured by a Modification in Diet in Renal Disease Study (MDRD) estimate of between 15 ml/min and 59 ml/min and and 0.5 g/day 2.5 times upper limit of normal. 3. Patients with history of congestive heart failure and NYHA Class III-IV symptoms at any time. 4. Patients for whom living donor renal transplantation is already scheduled or in the process of being evaluated, as these patients will be unlikely to complete study protocols before transplantation. 5. Patients with severe co-morbid conditions (eg, symptomatic hepatic cirrhosis, metastatic cancer, HIV infection with AIDS). 6. Patient with active inflammatory process (eg., SLE, rheumatoid arthritis, gout) for which they are currently receiving immune modulating medications. 7. Patients who are on corticosteroid therapy. 8. Patients who do not consent to participate in the study.
