摘  要:目的 调查分析慢性肾脏病(CKD)1~5D期患者的矿物质及骨代谢异常(Mineral and bone disorder,MBD)状况.方法 对2011年10月~2014年5月期间,于哈尔滨医科大学附属第一医院住院治疗及门诊规律行血液透析治疗的1318例CKD患者的矿物质及骨代谢相关指标进行回顾性调查分析,并对继发性甲状旁腺功能亢进的相关因素进行多元回归分析.结果 血清钙、磷和全段甲状旁腺素(iPTH)数值在CKD早期[GFR> 60 ml· min-1·(1.73m2)-1]并无明显异常,且在GFR> 30 ml· min-1·(1.73m2)-1前相对稳定,但进入CKD4期后,随着肾小球滤过率的进行性下降,血磷、iPTH急剧升高,血钙明显降低.血磷在CKD 1~5D期分别为:(1.13±0.20) mmol/L、(1.14±0.22) mmol/L、(1.26±0.23) mmol/L、(1.48±0.34) mmol/L、(2.05±0.61) mmol/L和(2.08±0.58) mmol/L;校正血总钙在CKD 1~5D期分别为:(2.35±0.13)mmol/L、(2.35±0.12) mmol/L、(2.35±0.15) mmol/L、(2.26±0.18) mmol/L、(2.07±0.29) mmol/L及(2.31±0.26) mmol/L;iPTH在CKD 1~5D期分别为:57.8 (45.6,91.8) ng/L、54.1 (37.8,74.6) ng/L、71.6(45.8,102.2) ng/L、131.1 (81.7,205.1) ng/L、277.5 (173.6,395.3) ng/L、354.9(194.4,720.3)ng/L.回归分析结果显示:血钙降低(OR=3.32,P<0.01)和GFR下降(OR=5.28,P< 0.01)为CKD 3~5期iPTH升高的独立危险因素.结论 从CKD3期开始,CKD患者的血钙、磷、iPTH水平出现明显异常,并且异常比例随着肾功能下降而进行性升高.进入CKD5D期,高磷、高iPTH水平并未因透析治疗得到明显改善,但血钙水平存在着明显的“矫枉过正”现象.Objective To investigate and analyze the mineral and bone disorder (MBD) in the patients with chronic kidney disease (CKD),reveal the change of related indexes of CKD-MBD.Methods A cross-sectional study was carried out in the First Affiliated Hospital of Harbin Medical University.From October 2011 to May 2014,1318 inpatients and hemodialysis outpatients were enrolled.Parameters related to MBD,including serum phosphorus (P),total calcium (t-Ca),intact parathyroid hormone (iPTH) and alkaline phosphatase (AKP) were analyzed.Last,it was analyzed with multiple regression analysis to related factors of the secondary hyperparathyroidism (SHPT) in patients with CKD.Results Serum calcium,phosphorus and iPTH had no obvious abnormalities at the early stages of CKD [GFR 〉 60 ml· min-1· (1.73 m2)-1],and relatively stable before GFR 〉 30 ml· min-1· (1.73m2)-1.After entering the CKD4 stage,serum phosphorus,iPTH increased sharply and serum calcium decreased obviously along with the decreased glomerular filtration rate (GFR).Serum P,t-Ca and iPTH levels were statistically significant in CKD 1 to 5D patients,respectively,serum P:(1.13±0.20) mmol/L,(1.14±0.22) mmol/L,(1.26±0.23) mmol/L,(1.48±0.34) mmol/L,(2.05±0.61) mmol/L and (2.08±0.58)mmol/L;serum t-Ca (mmol/L) (2.35±0.13) mmol/L,(2.35±0.12) mmol/L,(2.35±0.15) mmol/L,(2.26± 0.18) mmol/L,(2.07±0.29) mmol/L and (2.31±0.26) mmol/L;iPTH:57.8(45.6,91.8) ng/L,54.1(37.8,74.6) ng/L,71.6(45.8,102.2) ng/L,131.1(81.7,205.1) ng/L,277.5(173.6,395.3) ng/L and 354.9 (194.4,720.3) ng/L;The stepwise logistic regression analysis showed:hypocalcemia (OR=3.32,P 〈 0.01) and decreased GFR (OR=5.28,P 〈 0.01) were independent risk factors of iPTH elevation at stage CKD3~ 5.Conclusions From the beginning of the CKD3 stage,serum t-Ca,P,iPTH level began to be relatively abnormal as renal function declined.Hyperphosphatemia,SHPT has not been improved si
