[摘要] 目的 探讨维持性血液透析患者透析期血压变异性与CKD-MBD的相关性。 方法 回顾性分析2018年7月至2020年7月在我院治疗的透析患者112例,记录透析治疗参数、实验室检查指标和营养指标等,比较不同指标间的差异。 结果 与△SBP<10 mmHg患者比较,△SBP≥10 mmHg患者透析齡更长,P、PTH水平更高(P<0.05);P、PTH异常升高患者血压波动高于P、PTH正常患者,差异有统计学意义(P<0.05)。相关性分析显示,P、PTH与△SBP呈正相关(r=0.245,0.214,P<0.05);多因素分析显示,透析龄(OR=4.037)、P水平(OR=3.027)、PTH水平(OR=1.892)是血压波动的负性影响因素,尿素清除指数与ALB水平是血压波动的正性影响因素(P<0.05)。 结论 MHD患者治疗前后血压波动与CKD-MBD密切相关,同时受营养状态、透析龄、透析充分性等多种因素影响。

[Abstract] Objective To investigate the correlation between blood pressure(BP) variability and CKD-MBD during dialysis in maintenance hemodialysis patients. Methods A total of 112 dialysis patients admitted to our hospital from July 2018 to July 2020 were analyzed retrospectively. The parameters of dialysis treatment, laboratory examination and nutritional indexes were recorded, and the differences among various indexes were compared. Results Complicated with △SBP≥10 mmHg, the dialysis age of patients with △SBP<10 mmHg was longer, P and PTH levels were higher(P<0.05). The fluctuations of BP in patients with abnormally elevated P and PTH were higher than those in patients with normal P and PTH (P<0.05). It was shown by correlation analysis that P, PTH and △SBP were positively correlated (r=0.245, 0.214, P<0.05). It was shown by multivariate analysis that dialysis age (OR=4.037), P level (OR=3.027) and PTH level (OR=1.892) were negatively impacting factors of BP fluctuation, while urea clearance index and ALB level were positively impacting factors of BP fluctuation(P<0.05). Conclusion The BP fluctuation in MHD patients before and after treatment is closely related to CKD-MBD, and impacted by nutritional status, dialysis age, dialysis adequacy and other factors.

慢性肾脏病-矿物质和骨异常(Chronic kidney disease-mineral and bone disorder,CKD-MBD)是终末期肾脏病(End stage renal disease,ESRD)患者的常见并发症,是诱发不良心血管事件、增加死亡率的重要原因[1]。维持性血液透析(Maintenance hemodialysis,MHD)是目前临床治疗ESRD的主要手段。已有研究表明,ESRD患者在接受MHD治疗期间不良心血管事件发生率比正常人群增加8倍,其中大约80%患者存在血压波动加剧的症状[2]。近年已有研究者发现,血压波动是预测MHD治疗预后的重要因素[3],但是关于MHD治疗过程中的血压波动与CKD-MBD是否存在相关性,目前尚缺乏足够的循证医学依据。为此,本研究以我院2018年7月至2020年7月收治的112例MHD患者为研究对象,探讨CKD-MBD与血压波动的相关性,旨在进一步明确MHD治疗过程中导致患者发生CKD-MBD并发症的相关危险因素,以期为MHD临床治疗提供参考,现报道如下。
