摘要: 目的  探索维生素D2软胶囊对伴有糖尿病肾病(diabetic kidney disease,DKD)的2型糖尿病(type 2 diabetes mellitus,T2DM)患者蛋白尿水平的影响。方法  回顾性分析2020年10月至2022年3月在北京市某三级医院内分泌科住院治疗的估算肾小球滤过率(estimated glomerular filtration rate, eGFR)≥60 mL·(min·1.73 m2)-1的伴DKD的95例T2DM患者。根据患者的治疗方案分为未使用维生素D制剂的对照组(CON组,n=33)、 使用维生素D2软胶囊的普通维生素D组(NVD组,n=31)和使用骨化三醇软胶囊的活性维生素D组(AVD组,n=31)。通过医院病例系统收集基线和治疗12周时患者的临床资料及维生素D和DKD相关指标,包括血清25羟维生素D(25-hydroxy vitamin D,25OHD)、 血清甲状旁腺激素(parathyroid hormone,PTH)、血钙、尿钙和尿白蛋白与肌酐比值(urinary albumin-to-creatinine ratio,UACR)等。 结果  基线时CON组、NVD组和AVD组大量蛋白尿患者分别为8例(24.24% )、 9例(29.03 %)和7例(22.58% ),差异无统计学意义(P=0.831)。治疗12周时,NVD组和AVD组ln(UACR)水平均显著降低(P均<0.001),两治疗组间差异无统计学意义(P=0.371)。NVD组和AVD组的总有效率分别为80.65%和74.19%,显著高于CON组(33.33% )(P<0.001和P=0.002)。NVD组和AVD组的疗效差异无统计学意义(P=0.245)。CON组出现1例血钙增高、1例高尿钙、1例高尿酸血症、1例肾结石、1例肌肉痉挛;NVD组出现1例高尿钙、1例高尿酸血症;AVD组出现1例血钙增高、1例高钙血症、1例低PTH、2例高尿钙、2例高尿酸血症。两治疗组均无停药事件发生。结论  维生素D2软胶囊与骨化三醇软胶囊均可显著降低肾功能正常的伴DKD的T2DM患者尿蛋白水平。普通维生素D与活性维生素D相比可能安全性更好。

Abstract: Objective To explore the effects of vitamin D2 soft capsules and calcitriol soft capsules on albuminuria in type 2 diabetes mellitus(T2DM) patients with diabetic kidney disease(DKD). Methods Totally 95 T2DM patients with DKD and estimated glomerular filtration rate (eGFR)≥60 mL·(min·1.73 m2)-1 who hospitalized in the department of endocrinology  of a tertiary hospital in Beijing from October 2020 to March 2022 were analyzed retrospectively. According to the treatment protocols, the patients were divided into control group without vitamin D preparation (CON group, n=33), natural vitamin D group with vitamin D2 soft capsule (NVD group, n=31), and active vitamin D group with calcitriol soft capsule (AVD group, n=31). The clinical data and parameters of vitamin D and DKD, including serum 25-hydroxyvitamin D (25OHD), serum parathyroid hormone (PTH), blood calcium, urine calcium and urinary albumin-to-creatinine ratio (UACR) at baseline and after 12 weeks treatment were collected through the electronic medical records database system. Results In the baseline phase, there were 8 cases (24.24% ), 9 cases (29.03% ), and 7 cases (22.58% ) with macroalbuminuria in CON group, NVD group, and AVD group, respectively, with no significant difference(P=0.831)。After 12 weeks of treatment, the level of ln(UACR) decreased significantly(both P<0.001), with no significant difference between the two treatment groups(P=0.371). The total effective rates of NVD group and AVD group were 80.65%  and 74.19%  respectively, which were significantly higher than those of CON group(33.33% )(P<0.001 and P=0.002). There was no significant difference between NVD group and AVD group(P=0.245). There were 1 case of blood calcium increased, 1 case of hypercalciuria, 1 case of hyperuricemia, 1 case of kidney stone, and 1 case of muscle spasm in CON group, 1 case of hypercalciuria and 1 case of hyperuricemia in NVD group, 1 case of blood calcium increased, 1 case of hypercalcaemia, 1 case of blood parathyroid hormone decreased, 2 cases of hypercalciuria, and 2 cases of hyperuricemia in AVD group. No drug withdrawal occurred in both treatment groups. Conclusion The administration of both Vitamin D2 soft capsule and calcitriol soft capsule can effectively reduce albuminuria levels in T2DM patients with DKD with good renal function and significantly. Natural vitamin D may be safer compared with active vitamin D.
