过去 30 年,我们对构成肾性骨营养不良的矿物质、激素和骨骼疾病的发病机制的理解取得了实质性进展。 20 世纪 70 年代初期,骨化三醇和阿法骨化醇作为治疗这种疾病的药物被引入,代表了临床实践中的巨大进步,但不幸的是,这些疗法的后续改进仍然让我们距离理想还很遥远:维生素 D 代谢物引起的高磷酸盐血症和高钙血症,以及无法控制甲状旁腺增生,这些都仍然存在问题。使用阿法骨化醇和骨化三醇的新型脉冲疗法虽然明显有效,但在比较研究中尚未达到最初对优越性的高度期望。目前正在评估新的维生素 D 代谢物,其中一些在实验环境中表现出理想的选择性,降低磷酸盐和/或钙升高的趋势,同时保持对甲状旁腺的良好控制。其中,22-奥沙骨化三醇、帕立骨化醇(19 Nor-1,25 二羟基维生素 D2)和多克骨化醇(1 α-羟基维生素 D2)与安慰剂相比均显示出较高的疗效,但在 1970 年代和 1980 年代的类似研究中,阿法骨化醇和骨化三醇也显示出较高的疗效。将新型维生素 D 代谢物与当前标准疗法(阿法骨化醇或骨化三醇)进行比较的随机研究结果要么尚未获得,要么显示出与高钙血症、高磷血症和甲状旁腺功能亢进相关的不确定益处。这些新代谢物对日益流行的低周转骨病的影响尚不清楚,尽管实验证据表明骨骼水平上存在潜在的重要差异。
The past 30 years have seen substantial advances in our understanding of the pathogenesis of the mineral, hormonal and skeletal disorders that comprise renal osteodystrophy. The introduction of calcitriol and alfacalcidol as treatments for this disorder in the early 1970s represented an enormous step forward in clinical practice, but unfortunately, the subsequent refinement of these therapies still leaves us well short of the ideal: hyperphosphatemia and hypercalcemia induced by the vitamin D metabolites, and failure to control parathyroid hyperplasia, all remain problematic. Novel pulsed regimens using alfacalcidol and calcitriol, while clearly effective, have not fulfilled initial high expectations of superiority in the context of comparative studies. New vitamin D metabolites, some of which have exhibited desirable selectivity in experimental settings with reduced tendency to raise phosphate and/or calcium while maintaining good control of the parathyroid glands, are now being evaluated. Of these, 22-oxacalcitriol, paricalcitol (19 nor-1,25 dihydroxyvitamin D2) and doxercalciferol (1 alpha-hydroxyvitamin D2) have all shown high efficacy when compared with placebo, but so also did alfacalcidol and calcitriol in similar studies in the 1970s and 1980s. The results of randomized studies comparing the new vitamin D metabolites with current standard therapy (alfacalcidol or calcitriol) are either not yet available or show uncertain benefits in relation to hypercalcemia, hyperphosphatemia and hyperparathyroidism. The impact of these new metabolites on the increasing prevalence of low turnover bone disease is unknown, although experimentally there is evidence of potentially important differences at the level of the skeleton.
