    Analyses of morning blood pressure surge and clinical parameters in patients with idiopathic membranous nephropathy

    • 摘要: 目的 观察特发性膜性肾病(idiopathic membranous nephropathy,IMN)患者晨峰血压与临床指标的分析研究。方法 本研究为横断面研究,纳入IMN患者168例,根据其24 h动态血压情况,将纳入患者分为晨峰血压组及非晨峰血压组,计量资料采用t检验,等级资料采用秩和检验,比较两组间患者临床指标的差异,采用Logistic回归分析IMN患者晨峰血压的影响因素。结果 晨峰血压组和非晨峰血压组患者在年龄[(51.04±9.67)岁比(46.99±13.14)岁]、尿素氮[(5.90±1.59)mmol/L比(4.64±1.19) mmol/L]、血肌酐[(81.81±34.66) μmol/L比(69.58±24.97) μmol/L]、估算肾小球滤过率[(92.66±19.50) mL·min-1·(1.73 m2-1比(103.39±23.82) mL·min-1·(1.73m2-1]、血尿酸[(393.63±97.67)μmol/L比(347.37±94.03)μmol/L]、血浆白蛋白[(25.26±7.44)g/L比(28.41±5.50) g/L]、24 h尿蛋白定量[(6.37±4.43) g比(4.46±2.26) g]、肾间质损伤程度等方面差异有统计学意义(P<0.05),体重指数[(27.32±3.54)kg/m2比(26.49±4.11)kg/m2]、三酰甘油[(3.18±2.74)mmol/L比(2.96±1.78)mmol/L]、胆固醇[(6.75±1.80)mmol/L比(6.54±1.69)mmol/L]、高密度脂蛋白[(1.24±0.41) mmol/L比(1.30±0.41) mmol/L]、低密度脂蛋白[(4.54±1.48) mmol/L比(4.46±1.46) mmol/L]两组之间差异无统计学意义(P>0.05);单因素Logistic回归分析显示性别、尿素氮、血肌酐、估算肾小球滤过率、血尿酸、血浆白蛋白、肾间质损伤程度为晨峰血压升高的相关影响因素(P<0.05),多因素Logistic回归分析结果提示血尿酸、血浆白蛋白、肾间质损伤程度为晨峰血压升高的危险因素(P<0.05)。结论 晨峰血压升高患者肾间质损伤程度较非晨峰血压升高患者明显加重。血压,尤其是晨峰血压的干预治疗在膜性肾病患者中可能十分重要。

       

      Abstract: Objective To observe the effect of morning blood pressure surge on clinical parameters in patients with idiopathic membranous nephropathy(IMN). Methods For this cross-sectional study,168 patients with IMN were recruited and assigned into two groups according to the status of 24 h arterial blood pressure. The t-test or rank sum test was utilized for comparing the inter-group differences in clinical parameters. Logistic regression was employed for examining the influencing factors of morning blood pressure surge in IMN patients. Results Significant inter-group differences existed in age [(51.04±9.67) years vs(46.99±13.14) years],blood urea nitrogen(BUN) [(5.90±1.59) mmol/L vs(4.64±1.19) mmol/L],serum creatinine[(81.81±34.66) μmol/L vs(69.58±24.97) μmol/L],estimated glomerular filtration rate(eGFR) [(92.66±19.50)mL·min-1·(1.73m2-1 vs(103.39±23.82) mL·min-1·(1.73m2-1],uric acid[(393.63±97.67)μmol/L vs(347.37±94.03)μmol/L],albumin [(25.26±7.44)g/L vs(28.41±5.50)g/L],24 h urinary protein quantification[(6.37±4.43)g vs (4.46±2.26)g]and degree of renal interstitial injury(P<0.05). No significant inter-group differences existed in body mass index[(27.32±3.54) kg/m2 vs(26.49±4.11) kg/m2],triglyceride[(3.18±2.74) mmol/L vs(2.96±1.78)mmol/L],cholesterol[(6.75±1.80)mmol/L vs(6.54±1.69)mmol/L], high-density lipoprotein[(1.24±0.41)mmol/L vs(1.30±0.41)mmol/L]or low-density lipoprotein [(4.54±1.48)mmol/L vs(4.46±1.46)mmol/L] (P>0.05). Univariate Logistic regression analysis indicated that gender,BUN,serum creatinine,eGFR,uric acid(UA),albumin and renal interstitial injury were the relevant influencing factors of morning surge of blood pressure(P<0.05). Multivariate Logistic regression analysis revealed that UA,albumin and renal interstitial injury were risk factors for morning surge of blood pressure(P<0.05). Conclusion In patients with morning surge of blood pressure, degree of renal interstitial injury is significantly higher than that in those without. Thus interventional therapy of blood pressure is vital for IMN patients.
