Abstract

Abstract Introduction: Parathyroid hormone-lowering responses after administration of three different therapies capable of raising serum total 25-hydroxyvitamin D (25OHD) were evaluated in patients with secondary hyperparathyroidism (SHPT), vitamin D insufficiency (VDI) and stage 3 or 4 chronic kidney disease (CKD). Methods: Sixty-nine adult subjects with intact parathyroid hormone (iPTH) ≥85 and 10.3 mg/dL) occurred with PLDC. Hyperphosphatemia (>5.5 mg/dL) occurred once with ERC, eight times with HDC, three times with IRC and twice with PLDC. Conclusion: ERC was highly effective in both raising serum 25OHD and decreasing iPTH in patients with SHPT, VDI and stage 3 or 4 CKD. iPTH-lowering response rates with ERC were similar to daily PLDC, the reference therapy; rates with IRC or HDC were significantly lower. ERC is an attractive alternative to vitamin D hormone therapy in CKD patients.
