Study of Sodium Bicarbonate in Kidney Transplant Recipients

Summary

The purpose of this study is to compare the effect of sodium bicarbonate versus no sodium bicarbonate treatment on urinary ammonia levels and urinary transforming growth factor-beta1 (TGF-beta1) excretion in renal transplant patients with low-to-normal serum bicarbonate levels (20 - 28 mmol/L).
