摘要:
目的 探讨乙型肝炎肝硬化患者3年内发生慢性肾病(CKD)的影响因素。 方法 纳入2014年1月—2017年7月就诊于首都医科大学附属北京地坛医院的乙型肝炎肝硬化患者376例,随访3年,根据是否发生CKD分为CKD组(n=23)和非CKD组(n=353)。收集患者一般情况和实验室指标。计量资料两组间比较采用t检验或Mann-Whitney U检验。计数资料两组间比较采用χ2检验或Fisher精确概率法。采用多因素Cox逐步向前回归方法,分析乙型肝炎肝硬化患者3年内发生CKD的独立影响因素。采用受试者工作特征曲线下面积(AUC)评估影响因素对乙型肝炎肝硬化患者发生CKD的预测价值,Kalplan-Merier法进行生存分析,log-rank检验比较不同风险患者CKD累积发生率。 结果 Cox多因素分析显示,年龄(HR=1.078,95%CI:1.007~1.114,P=0.026)、Alb(HR=0.923,95%CI:0.860~0.989,P=0.024)、肾小球滤过率(eGFR)(HR=0.977,95%CI:0.955~0.999,P=0.037)是乙型肝炎肝硬化患者3年内发生CKD的独立影响因素。年龄、Alb、eGFR对CKD发生的预测价值较好(受试者工作特征曲线下面积分别为0.701、0.710、0.706)。Kalplan-Merier生存曲线显示,基线年龄≥55岁、Alb<32 g/L、60 ml·min-1·1.73m-2≤eGFR<76 ml·min-1·1.73m-2的患者发生CKD的风险高(χ2值分别为9.647、13.621、30.940,P值均<0.05)。 结论 高龄、低Alb水平及eGFR较低的患者建议密切监测肾功能。 Abstract:Objective To investigate the influencing factors for chronic kidney disease (CKD) in patients with hepatitis B cirrhosis within 3 years. Methods A total of 376 patients with hepatitis B cirrhosis who attended Beijing Ditan Hospital, Capital Medical University, from January 2014 to July 2017 were enrolled and followed up for 3 years, and according to the presence or absence of CKD, they were divided into CKD group with 23 patients and non-CKD group with 353 patients. Related general information and laboratory markers were collected. The t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups; a stepwise forward Cox regression analysis was used to screen out the independent influencing factors for CKD within 3 years in patients with hepatitis B cirrhosis. The area under the receiver operating characteristic curve (AUC) was used to investigate the value of the influencing factors in predicting CKD in patients with hepatitis B cirrhosis; the Kaplan-Meier method was used for survival analysis, and the log-rank test was used for comparison of the cumulative incidence rate of CKD between the patients with different risks. Results The multivariate Cox regression analysis showed that age (hazard ratio [HR]=1.078, 95% confidence interval [CI]: 1.007-1.114, P=0.026), albumin (Alb) (HR=0.923, 95% CI: 0.860-0.989, P=0.024), and estimated glomerular filtration rate (eGFR) (HR=0.977, 95% CI: 0.955-0.999, P=0.037) were independent influencing factors for CKD within 3 years in patients with hepatitis B cirrhosis. Age, Alb, and eGFR had a relatively good value in predicting CKD, with AUCs of 0.701, 0.710, and 0.706, respectively. The Kaplan-Meier survival curve showed that the patients with baseline age ≥55 years, Alb < 32 g/L, and eGFR ≥60 ml·min-1·1.73 m-2 and < 76 ml·min-1·1.73 m-2 had a higher risk of CKD (χ2=9.647, 13.621, and 30.940, all P < 0.05). Conclusion Renal function should be closely monitored for patients with old age and low Alb and eGFR levels. -
