[摘要] 糖尿病肾病是糖尿病最常见的微血管并发症之一。随着病程的进展,加重了营养物质维生素D的丢失,同时对维生素D的羟化不足,共同导致骨质疏松的发生,属于中医肾主骨生髓理论。维生素D是一种类固醇激素,其缺乏不仅导致骨质疏松,而且参与糖尿病肾病发生、发展。骨质疏松给家庭、社会带来重担,引起越来越多人的重视。

[Abstract] Diabetic nephropathy is one of the most common microvascular complications of diabetes. With the progress of the course of the disease, the loss of vitamin D increases, and the lack of hydroxylation of vitamin D lead to the occurrence of osteoporosis, which belongs to the kidney main bone marrow theory of traditional Chinese medicine. Vitamin D is a steroid hormone, and its deficiency is not only linked to osteoporosis, but also to the development of diabetic kidney disease. Osteoporosis brings heavy burden to family and society, which attracts more and more people′s attention.

2型糖尿病起病隱匿,多数患者一经确诊已合并视网膜、肾脏、周围神经多种慢性微血管并发症。近几年,研究发现,2型糖尿病患者的骨质疏松症明显高于普通人,预计到2025年,其发生率可增加30%~50%[1]。糖尿病合并肾脏病时,钙磷代谢、25羟维生素D、骨密度等均发生了相应变化。维生素D与2型糖尿病肾病的发病、进展密不可分。维生素D发挥作用的主要器官即肾脏,维生素D受体选择性地分布于肾脏的肾小球、肾小管、髓袢等部分,维生素D对肾脏的保护作用需维生素D与其受体充分结合发挥作用。肾脏又在骨代谢中起重要作用。中医理论认为肾在体合骨,生髓。肾藏精,精生髓,髓充于骨即骨髓。骨的生长有赖于肾精的充盈。肾精充足,骨有所养,则骨骼坚固有力。若肾精不足,骨髓生化无源,骨失所养,则会导致小儿囟门迟闭,骨软无力,骨质疏松,乃至骨折的发生。基于以上理论,探讨糖尿病肾病与维生素D、骨质疏松的关系,为糖尿病骨质疏松症做好预防。……
