Native hypovitaminosis D (n-hVITD) is frequently found from the early stages of chronic kidney disease (CKD) and its prevalence increases with CKD progression. Even if the implications of n-hVITD in chronic kidney disease-mineral bone disorder (CKD-MBD) have been extensively characterized in the literature, there is a lot of debate nowadays about the so called "unconventional effects" of native vitamin D (25(OH)VitD) supplementation in CKD patients. In this review, highlights of the dimension of the problem of n-hVITD in CKD stages 2-5 ND patients will be presented. In addition, it will focus on the "unconventional effects" of 25(OH)VitD supplementation, the clinical impact of n-hVITD and the most significant interventional studies regarding 25(OH)VitD supplementation in CKD stages 2-5 ND.
原发性维生素 D 缺乏症(n-hVITD)在慢性肾脏病(CKD)的早期阶段经常被发现,其患病率随着 CKD 的进展而增加。尽管 n-hVITD 在慢性肾脏病-矿物质骨异常(CKD-MBD)中的意义在文献中已经得到广泛描述,但目前对于 CKD 患者中天然维生素 D(25(OH)VitD)补充的所谓“非常规作用”仍存在很多争议。在这篇综述中,将介绍 2-5 期非透析 CKD 患者中 n-hVITD 问题的重要方面。此外,还将重点介绍 25(OH)VitD 补充的“非常规作用”、n-hVITD 的临床影响以及关于 2-5 期非透析 CKD 患者中 25(OH)VitD 补充的最有意义的干预性研究。
