Sodium bicarbonate replacement delays progression of chronic kidney disease

In the latest edition of the Journal American Association of Nephrology, investigators report that sodium bicarbonate administration delays the progression of kidney disease to end-stage renal failure. 134 adult patients with CKD (creatinine clearance [CrCl] 15 to 30 ml/min per 1.73 m2) and serum bicarbonate 16 to 20 mmol/L to either supplementation with oral sodium bicarbonate or standard care for 2 yr. With this simple intervention, patients receiving sodium bicarbonate were significantly less likely to experience rapid progression (9 versus 45%; relative risk 0.15; 95% confidence interval 0.06 to 0.40; P < 0.0001). Compared with the control group, decline in CrCl was slower with bicarbonate supplementation (5.93 versus 1.88 ml/min 1.73 m2; P < 0.0001). Nutritional parameters were improved as well. This very simple intervention, practiced variably by nephrologists, shows great promise in the management of patients with chronic kidney disease.
