摘  要:目的分析慢性肾脏病(CKD)1—5D期患者钙磷代谢、甲状旁腺激素和骨转换生物化学标志物BMT的变化,为CKD各期矿物质和骨异常的诊治提供依据。方法收集2013年1月至2015年10月北京积水潭医院诊治的CKD患者142例,根据估算肾小球滤过率(eGFR)分为CKD1~5D期,比较各期患者的校正血钙、血磷、全段甲状旁腺激素(iPTH)、碱性磷酸酶(ALP)、总I型前胶原氨基端延长肽(tPINP)、I型胶原羧基端肽13特殊序列(β-CTX)、骨钙素的水平,评估校正血钙、血磷达标率、继发性甲状旁腺功能亢进的发生率,分析CKD各期钙磷代谢、iPTH与BMT变化趋势,各项指标行相关性分析。结果CKD3~5D期:校正血钙达标比例分别为90.0%(27/30),88.9%(16/18),82.1%(23/28),76.5%(13/17);高钙血症比例分别为3.3%(1/30),5.6%(1/18),7.1%(2/28),17.6%(3/17);血磷达标比例分别为86.7%(26/30),77.8%(14/18),28.6%(8/28),41.2%(7/17);高磷血症比例分别为0.0%(0/30),16.7%(3/18),60.7%(17/28),47.1%(8/17)。CKD5D期iPTH〉300ng/L的比例为41.2%(7/17),iPTH〈150ng/L的比例为35.3%(6/17)。因年龄在CKD1~5D期之间差异有统计学意义,将患者分为〈70岁组(100例)、≥70岁组(42例)对观察指标进行分组比较。〈70岁组血磷于CKD5、5D期高于CKD1~4期;tPINP于CKD4~5D期均高于CKD1~3期;13-CTX、骨钙素、iPTH于CKD4~5期均高于CKD1~3期,于CKD5D期高于CKD1~5期。≥70岁组血磷于CKD5D期高于CKD1~5期;tPINP、骨钙素于CKD5期均高于CKD1~4期,CKD5D期高于CKD1~5期;β-CTX于CKD5~5D期均高于CKD1~4期;iPTH于CKD5期均高于CKD1~4期,于CKD5D期高于CKD1—3期,差异均有统计学意义(均P〈0.05)。eGFR与血磷、tPINP、β-CTX、骨钙素、Objective To analyze the change of calcium-phosphorus metabolism, parathyroid hormone and biochemical marker of bone turnover (BMT) in patients with chronic kidney disease (CKD) from stage 1 to 5D. Methods Totally 142 patients with CKD from January 2013 to October 2015 were divided into stages 1, 2, 3, 4, 5, and 5D according to the estimated glomerular filtration rate (eGFR). The levels of serum calcium, phosphorus, intact parathyroid hormone (iPTH), alkaline phosphatase (ALP), total N-terminal propeptide of type I procollagen (tPINP), 13-C-terminal telopeptide of type I collagen (β-CTX) and osteocalcin (OC) were ana- lyzed. The up-to-standard rates of serum calcium and phosphorus, the incidence of secondary hyperparathyroidism, the changing tendencies of calcium-phosphorus metabolism, iPTH and BMT were analyzed. Results At stage 3-5D, the up-to-standard rates of serum calcium were respectively 90. 0% (27/30) , 88.9% (16/18) , 82. 1% (23/28) and 76. 5% (13/17) ; the rates of hypercalcemia were respectively 3.3% ( 1/30), 5.6% (1/18) , 7. 1% (2/28) and 17.6% (3/17); the up-to-standard rates of serum phosphorus were respectively 86.7% (26/30), 77.8% (14/18), 28.6% (8/28) and 41.2% (7/17) ; the rates of hyperphosphatemia were respec- tively 0. 0% (0/30), 16. 7% (3/18), 60. 7% (17/28) and 47. 1% (8/17). At stage 5D, the rate of iPTH 〉 300 ng/L was 41.2% (7/17) and the rate of iPTH 〈 150 ng/L was 35.3% (6/17). As there were statistically significant differences of age among stages 1-5D, all patients were divided into 〈 70 years old group (100 cases) and t〉70 years old group (42 cases). In 〈70 years old group, the levels of serum phosphorus at stages 5-5D were higher than those at stages 1-4; the levels of tPINP at stages 4-5D were higher than those at stages 1-3; the levels of [3-CTX, OC and iPTH at stages 4-5 were higher than those at stages 1-3, and at stage 5D were higher than those at stages 2-
