    • The method of treating elevated blood levels of iPTH by increasing or maintaining blood concentrations of both 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D in a patient by administering, as necessary, both Vitamin D repletion and Vitamin D hormone replacement therapies, is disclosed. The blood concentrations of 25-hydroxyvitamin D are increased to and maintained at or above 30 ng/mL, and blood concentrations of 1,25-dihydroxyvitamin D are increased to or maintained within a patient's normal historical physiological range for 1,25-dihydroxyvitamin D without causing substantially increased risk of hypercalcemia, hyperphosphatemia or over suppression of plasma iPTH in the patient. The blood levels of 25-hydroxyvitamin D are maintained at or above 30 ng/mL between doses of Vitamin D repletion therapies, and the blood levels of 1,25-dihydroxyvitamin D are maintained in the patient's normal historical physiological range between doses of Vitamin D hormone replacement therapies. In one aspect, the disclosure includes methods wherein the blood concentration of 25-hydroxyvitamin D during treatment comprises predominantly 25-hydroxyvitamin D3, and/or wherein the method includes administering predominantly or solely 25-hydroxyvitamin D3 for 25-hydroxyvitamin D repletion and/or maintenance.
    • 公开了通过根据需要施用维生素D补充剂和维生素D激素替代疗法来增加或维持25-羟基维生素D和1,25-二羟基维生素D的血液浓度来治疗iPTH升高的血液水平的方法 。 25-羟基维生素D的血液浓度增加并保持在30ng / mL以上,1,25-二羟基维生素D的血液浓度增加至1,25-二羟基维生素D的患者正常的历史生理范围内 而不会导致患者高钙血症,高磷血症或过度抑制血浆iPTH的风险显着增加。 在维生素D补充疗法的剂量之间,25-羟基维生素D的血液水平维持在或高于30ng / mL,1,25-二羟基维生素D的血液水平维持在维生素D剂量之间的患者正常的历史生理范围内 激素替代疗法。 一方面,本公开内容包括其中治疗期间25-羟基维生素D的血液浓度主要包含25-羟基维生素D3和/或其中所述方法包括主要或单独使用25-羟基维生素D补充的25-羟基维生素D3用于25-羟基维生素D补充和/或 保养。
