摘  要:目的 探讨慢性阻塞性肺疾病(COPD)患者早期肾损伤指标变化及其临床意义.方法 选择2014年1月至2016年12月我院收治的90例COPD患者,其中COPD稳定期45例,COPD急性加重期45例,同时选择45例同期健康体检者作为对照组.根据缺氧程度,将COPD患者分为轻度亚组(60 mmHg〈PaO2≤80 mmHg,48例)、中度亚组(40 mmHg〈PaO2≤60 mmHg,30例)、重度亚组(PaO2≤40 mmHg,12例).检测各组血清胱抑素C(CysC)、β2微球蛋白(β2-MG)、肌酐(Scr)、C反应蛋白(CRP),并计算肾小球滤过率(eGFR),同时采用心脏多普勒超声测定左室舒张末期内径(LVEDD)、左室射血分数(LVEF).结果 对照组、COPD稳定期组、急性加重期组比较血清Cys-C [(104.5±20.9、133.9±15.4、147.8±21.2) μg/L]、β2-MG[(1.5±0.3、2.4±0.4、2.8±0.4) mg/L]、Scr[(74.4±10.7、81.1±17.5、90.4±20.3) nmol/l] 、eGFR[(97.2±14.8、89.9±18.6、78.3±17.8) ml/min·1.73 m2]差异均有统计学意义(F值分别为12.18、4.97、7.39、8.16,P均〈0.05);且与对照组比较,COPD稳定期组、急性加重期组Cys-C、β2-MG、Scr均明显升高,而eGFR则明显降低,差异均有统计学意义(P均〈0.05);急性加重期组各早期肾功能指标与COPD稳定期组比较,差异均有统计学意义(P均〈0.05).与对照组比较,不同亚组COPD患者血清Cys-C、β2-MG均明显升高,且随着缺氧程度的增加而增加[Cys-C: (104.5±20.9、122.8±22.5、136.7±31.6、150.8±39.7) μg/L;β2-MG:(1.5±0.3、1.9±0.3、2.4±0.5、2.9±0.4) mg/L;Scr:(74.4±10.7、78.6±12.4、82.1±13.4、94.8±17.3) nmol/L;eGFR:(97.2±14.8、93.8±15.3、88.6±12.2、74.4±10.7) ml/min·1.73m2](P均〈0.05);与对照组、轻度亚组比较,中度、重度亚组Scr明显升高,eGFR明显降低(P均〈0.05).CRP 与Cys-C、β2-MG均呈显著正相关(r=0.407,0.379),LVEF与Cys-C、β2-MG、Scr均呈显著负相关(r值分别为-0.488、-0.391、-0.306�Objective To explore the indicators change of early renal injury in patients with chronic obstructive pulmonary disease (COPD) and its clinical significance.Methods Ninety cases of COPD including 45 cases with stable period of COPD,45 cases with acute exacerbation of COPD who received treatment in Baoshan Branch of Shanghai General Hospital from January 2014 to December 2014 were enrolled in this study.Meanwhile 45 cases of healthy subjects were collected as the control group.According to the extent of hypoxia,the COPD patients were divided into mild subgroups (60mmHg〈PaO2≤80mmHg,48 cases),moderate subgroups (40mmHg〈PaO2≤60mmHg,30 cases),severe subgroups (PaO2≤40mmHg,12 cases).The levels of serum cystatin C (CysC),β2-microglobulin (β2-MG),serum creatinine (Scr) and C-reactive protein (CRP) were detected among all groups,and estimated glomerular filtration rate (eGFR) was calculated,left ventricular end-diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF) were measured by Cardiac Doppler ultrasound.Results Serum Cys-C,β2-MG,Scr values and eGFR values were significantly lower in the control group than in the stable period group and acute exacerbation group,(Cys-C: (104.5±20.9) μg/L vs.(133.9±15.4) μg/L vs.(147.8±21.2) μg/L);β2-MG: (1.5±0.3) mg/L vs.(2.4±0.4) mg/L vs.(2.8±0.4) mg/l);Scr: (74.4±10.7) nmol/L vs.(81.1±17.5) nmol/L vs.(90.4±20.3) nmol/L);eGFR: (97.2±14.8) ml/min·1.73m2 vs.(89.9±18.6) ml/min·1.73m2 vs.(78.3±17.8) ml/min·1.73m2,F=12.18,4.97,7.39,8.16,P〈0.05).Compared with the control group,the levels of serum Cys-C,β2-MG and Scr in all the COPD subgroups were significantly increased,an obvious decrease was seen in eGFR value,the differences were all statistically significant (P〈0.05).There was significant difference on indicators of early renal injury between stable period group and acute exacerbation period group (P〈0.05).Compared
