Recent evidence suggested that the efficacy of folic acid supplementation in reducing plasma total homocysteine (Hcy) concentration might be similar in renal transplant recipients (RTR) and chronic kidney disease (CKD) patients with a comparable degree of reduction of renal function. However, a direct comparison of the response to high dose folic acid supplementation between renal transplant recipients and CKD patients has never been made. Therefore, the goal of this study was to evaluate the response to folic acid (5 mg/day) supplementation in 15 stable renal transplant recipients with evidence of chronic allograft nephropathy, and in 15 CKD (stage 3) patients matched for age, sex and renal function living in the area of Skopje, Macedonia. After 12 weeks of folic acid supplementation, plasma total Hcy concentrations were significantly reduced in the two groups. Percent reduction of plasma total Hcy levels was nearly identical in the two groups (25.7% vs 24.5%, p=NS). These results confirm previous findings regarding the efficacy of folic acid therapy given separately to either renal transplant recipients or CKD patients, and extend them to a direct confirmation of identical efficacy.
