目的 :从普通血液和生化指标中寻找与维持性血液透析患者难治性高血压(treatment resistant hypertension,TRH)相关的危险因素,为透析患者的高血压治疗提供帮助。方法:2009年12月—2015年6月在南京医科大学第一附属医院行规律血液透析的高血压患者174例,其中病例组TRH患者69例,对照组非TRH患者105例。采用Logistic回归分析,寻找与TRH相关的危险因素。结果:两组患者性别、肌酐水平和透析时长上差异无统计学意义。病例组平均年龄、尿酸、血白细胞、天门冬氨酸氨基转移酶(aspertate aminotransferace,AST)、谷氨酰转肽酶(gamma-glutamyl transferase,GGT)和腺苷脱氨酶(adenosine deaminase,ADA)水平均显著低于对照组;而病例组血清钙和白蛋白(albumin,ALB)显著高于对照组。单因素Logistic回归显示:年龄<40岁(OR:3.350,P=0.010)、GGT<20 U/L(OR:2.554,P=0.024)、10 U/L≤AST<15 U/L(OR:2.499,P=0.011)、ADA<12 U/L(OR:2.259,P=0.044)是透析患者TRH的危险因素;ALB<41 g/L是保护因素(OR:0.298,P=0.002)。逐步法多因素Logistic回归分析显示:ALB水平与TRH呈正相关(OR:1.130,P=0.002),ADA水平与TRH呈负相关(OR:0.900,P=0.027)。结论:年龄<40岁、血清GGT<20 U/L、10≤AST<15 U/L和ADA<12 U/L是维持性血液透析患者TRH的危险因素,而血清ADA降低和血清ALB升高是TRH的独立危险因素。
Objective: To find out the risk factors related to treatment resistant hypertension (TRH) in patients with maintenance hemodialysis from general blood and biochemical indexes, and to provide help for the treatment of hypertension in dialysis patients. Methods: From December 2009 to June 2015, 174 patients with regular hemodialysis hypertension were admitted to the First Affiliated Hospital of Nanjing Medical University, including 69 cases of TRH in the case group and 105 cases of non-TRH patients in the control group. Logistic regression analysis was used to find the risk factors associated with TRH. Results: There was no significant difference in gender, creatinine and dialysis duration between the two groups. The mean age, uric acid, white blood cells, aspertate aminotransferace (AST), glutamyl transferase (GGT) and adenosine deaminase (ADA) Levels were significantly lower than the control group; while serum albumin (albumin, albumin, albumin, ALB) were significantly higher than the control group. Univariate Logistic regression analysis showed that age less than 40 years (OR: 3.350, P = 0.010), GGT less than 20 U / L (OR 2.554, P = 0.024) 2.499, P = 0.011). ADA <12 U / L (OR: 2.259, P = 0.044) was a risk factor for TRH in dialysis patients; ALB <41 g / L was a protective factor (OR: 0.298, P = 0.002). Logistic regression analysis showed that there was a positive correlation between ALB level and TRH (OR: 1.130, P = 0.002). ADA level was negatively correlated with TRH (OR: 0.900, P = 0.027). CONCLUSIONS: Age <40 years, serum GGT <20 U / L, 10≤AST <15 U / L and ADA <12 U / L are risk factors for TRH in maintenance hemodialysis patients, while serum ADA is decreased and serum ALB is elevated Is an independent risk factor for TRH.
