Background: Recent publications show that elevation of FGF23 is independently associated with progression or renal disease, left ventricular hypertrophy and cardiovascular mortality. Dietary restriction of phosphate and phosphate binders are used for control phosphate balance and elevation of serum FGF23 levels. The aim of this study is to compare the effectiveness of calcium carbonate vs. lanthanum carbonate in reducing serum FGF23 levels in Chronic Kidney Disease (CKD) patients. Methods: 32 patients from the Nephrology outpatient clinic with CKD 4 - 5 non-dialysis were included. Patients receive a 4-month treatmentperiod of calcium carbonate or lanthanumcarbonate. Patients had normal serum calciumconcentration, 25 (OH) levels >30 ng/ml and they were not on VDR activators or cinacalcet. Results: As compared with calcium carbonate, patients on lanthanum carbonate had lower serum levels of FGF23 (226 ± 11 vs. 158 ± 9 pg/ml) and less urinary excretion of phosphate. No significant changes in serum calcium and PTH levels were observed in both groups. Conclusions: In conclusion, in CKD 4 - 5 patients lanthanum carbonate is effective in reducing phosphate load and FGF23 levels; this effect was not observed with calcium carbonate.
