摘  要:目的评价白细胞总数、血红蛋白、生化指标、红细胞沉降率、免疫球蛋白(Ig)水平对80岁及以上患者死亡的远期预后价值。方法对342例常规查体的老人进行随访,年龄80~94岁,平均(85.6±4.0)岁,随访2~119个月,平均(82.0±36.9)个月,记录死亡原因和死亡时间。结果与存活组(132例)比较,死亡组(198例)年龄大,分别为(86.5±4.4)岁与(84.5±3.2)岁(t=4.86,P〈0.01),白细胞总数高[(6.2±1.7)×10^9/L比(5.5±1.3)×10^9/L,t=-3.93,P〈0.01],血红蛋白低[(134.4±14.4)g/L比(140.0±12.6)g/L,t=3.65,P〈0.001],红细胞沉降率快[中位数为11mm/h(四分位数间距为15mm/h)比中位数为9mm/h(四分位数间距为10mm/h),U=-3.31,P〈0.01],IgM低[(0.9±0.5)mg/L比(1.1±0.8)mg/L,t=2.55,P〈0.05],尿素稍高[(7.5±2.6)mmol/L比(6.8±1.6)mmol/L,t=-2.81,P〈0.01],肌酐高[(113.0±32.5)umol/L比(100.5±15.8)umol/L,t=-4.65,P〈0.01]。Cox多元回归分析结果显示,年龄(RR=1.083,95%CI为1.040~1.127,P〈0.01)、血红蛋白(RR=0.835,95%CI为0.714~0.975,P〈0.05)、白细胞总数(RR=1.134,95%C1为1.021~1.260,P〈0.05)、IgM(RR=0.710,95%CI为0.521~0.966,P〈0.05)、肌酐(RR=1.011,95%CI为1.002~1.020,P〈0.05)、主动脉瘤(RR=2.144,95%CI为1.163~3.951.P〈0.05)是预测80岁及以上患者死亡的独立危险因子。结论在80岁及以上患者中,年龄增加、白细胞总数升高、血红蛋白降低、IgM降低、肌酐升高、并存主动脉瘤是全因死亡的独立危险因素,对于80岁及以上患者预后判断有一定的临床意义。Objective To evaluate the prognostic values of leukocyte count, hemoglobin, biochemical parameters, erythrocyte sedimentation rate and immunoglobulin on mortality in patients aged 80 years and over. Methods Totally 342 patients(aged 85.6±4.0 years)were followed-up for (82.0±36.9) months, and the cause and time of death were recorded. Results During the period of follow up, 198 patients suffered from death. Compared with the survival group (132 cases) , the death group had older age [ (86.5±4.4)years vs. (84.5±3.2)years,t=-4.86,P〈0.01) ,higher white blood cell [ (6.2±1.7)× 10^9/L vs. (5.5±1.3)× 10^9/L,t=-3.93,P〈0.01 ] , lower hemoglobin [(134.4+[14.4)g/L vs. (140.0±12.6)g/L,t =3.65,P〈0.01 ] ,slightly faster erythrocyte sedimentation rate [ 11 mm/h(15 mm/h) vs. 9 mm/h (10 mm/h),U=-3.31,P〈 0.01 ] ,lower immunoglobulin M [ (0. 9±0. 5)mg/L vs. (1.1±0.8)mg/L, t= 2.55, P〈0.05 ] , slightly higher urea nitrogen [ (7.5±2.6) mmol/L vs. (6.8±1.6) mmol/L, t=-2.81, P〈0.01 ] and creatinine [ (113.0±32.5) umol/L vs. (100.5±15.8) umol/L, t=-4.65, P〈0.01 ] . Cox multivariate analysis revealed that older age (RR= 1. 083, 95%CI: 1.040-1. 127, P〈0.01), white blood cell count (RR=1. 134, 95%CI:1. 021-1. 260, P〈0.05), ereatinine (RR=1. 011, 95% CI 1.002-1.020, P〈0.05), hemoglobin(RR=0.835,95% CI:0. 714-0.975, P〈0.05)and immunoglobulin M(RR=0. 710,95% CI:0. 521-0. 966, P〈0.03), aortic aneurysm(RR=2. 144,95% CI:1. 163 3. 951, P〈 0.05) were the independent risk factors for death. Conclusions Aging, increased WBC count, decreased hemoglobin and immunoglobulin M, elevated ereatinine and aortic aneurysm are the independent risk factors for death,which are powerful parameters for the prognostic evaluation in the elderly aged 80 years and over.
