摘要:

目的 探讨肾病综合征(NS)患者生物可利用1,25-羟基维生素D[1,25(OH)2D]水平与骨密度(BMD)及骨代谢标志物的相关性。方法 选取NS患者80例(NS组),同时以性别、年龄、体质量指数(BMI)相近的体检健康者60名作为正常对照组。记录所有对象的性别、年龄、身高、体质量、血压、吸烟史、嗜酒史等信息,计算BMI;同时检测股骨颈BMD及血清肌酐(SCr)、总胆固醇(TC)、三酰甘油(TG)、白蛋白(Alb)、钙、磷、全段甲状旁腺激素(iPTH)、总1,25(OH)2D、维生素D结合蛋白(DBP)水平,计算生物可利用1,25(OH)2D。采用多元Logistic回归分析评估各项指标与1,25(OH)2D水平的相关性。结果 NS组收缩压及血清Alb、钙、总1,25(OH)2D、生物可利用1,25(OH)2D水平明显低于正常对照组(P<0.05),而舒张压及血清TC、TG、磷、iPTH明显高于正常对照组(P<0.05)。2个组之间吸烟史比例、嗜酒史比例、SCr、估算肾小球滤过率(eGFR)、血清DBP、BMD差异均无统计学意义(P<0.05)。NS患者总1,25(OH)2D及生物可利用1,25(OH)2D水平与BMD、Alb、DBP均呈正相关(P<0.01),与iPTH、TC均呈负相关(P<0.01),与其他指标无相关性(P>0.05)。结论 NS患者总1,25(OH)2D、生物可利用1,25(OH)2D水平偏低,且与BMD及骨代谢标志物相关。

Abstract:

Objective To investigate the correlation between bioavailable 1,25-hydroxyvitamin D [1,25(OH)2D] level and bone mineral density(BMD) and bone metabolic markers in patients with nephrotic syndrome(NS). Methods A total of 80 NS patients(NS group) and 60 healthy subjects(healthy control group) with similar sex,age and body mass index(BMI) were enrolled. The data on sex,age,height,weight,blood pressure,smoking history and drinking history of all the subjects were recorded,and BMI was calculated. The BMD,serum creatinine(SCr),total cholesterol(TC),triglyceride(TG),albumin(Alb),calcium,phosphorus,intact parathyroid hormone(iPTH),total 1,25(OH)2D and vitamin D binding protein(DBP) were determined,and bioavailable 1,25(OH)2D was calculated. Multivariate Logistic regression analysis was used to evaluate the correlations between the indicators and 1,25(OH)2D levels. Results The systolic blood pressure,serum Alb,Ca,total 1,25(OH)2D and bioavailable 1,25(OH)2D levels in NS group were lower than those in healthy control group(P<0.05),and the diastolic blood pressure and serum TC,TG,phosphorus and iPTH were higher than those in healthy control group(P<0.05). There was no statistical significance between the 2 groups in smoking history ratio,drinking history ratio,SCr,estimated glomerular filtration rate(eGFR),serum DBP and BMD (P>0.05). Total 1,25(OH)2D and bioavailable 1,25(OH)2D levels in NS group were positively correlated with BMD,Alb and DBP(P<0.01) and were negatively correlated with iPTH and TC(P<0.01),and there was no correlation with the other indicators(P>0.05). Conclusions Low levels of total 1,25(OH)2D and bioavailable 1,25(OH)2D in NS group are related to BMD and bone metabolic markers.
