目的:探讨急性呼吸窘迫综合征(ARDS)患者血管生成素2(Ang-2)的水平变化与肺损伤程度和预后的关系及其临床意义。方法采用前瞻性观察性研究方法,选择安徽医科大学第三附属医院重症医学科2012年1月至2014年3月收治的ARDS患者53例,按ARDS柏林定义分为轻度(15例)、中度(22例)、重度(16例)3组,按28 d转归分为生存组(29例)和死亡组(24例)。以同期20例非ARDS患者作为对照。记录患者入院24 h内急性生理学与慢性健康状况评分系统Ⅱ(APACHEⅡ)评分、序贯器官衰竭评分(SOFA)、氧合指数(PaO2/FiO2)、肺损伤评分(LIS),检测血浆Ang-2、白细胞介素-6(IL-6)、C-反应蛋白(CRP)水平。采用单因素和多因素logistic回归方法分析影响ARDS预后的危险因素;绘制受试者工作特征曲线(ROC),评价Ang-2在预测ARDS中的价值。结果与非ARDS组比较,ARDS组APACHEⅡ、SOFA、LIS评分明显升高, PaO2/FiO2明显降低,病死率明显增加,血浆Ang-2、IL-6、CRP水平明显升高〔APACHEⅡ(分):20.7±5.0比14.1±5.3,SOFA(分):7.7±3.5比3.5±2.1,LIS(分):1.69±0.71比0.28±0.27,PaO2/FiO2(mmHg,1 mmHg=0.133 kPa):159.5±61.3比394.0±63.2,病死率:45.3%(24/53)比20.0%(4/20),Ang-2(μg/L):4.73(2.59,6.99)比1.22(0.61,1.52),IL-6(ng/L):56.50(27.15,139.90)比13.05(4.38,15.55),CRP(mg/L):95.75(41.74,189.72)比10.56(3.92,21.36),P<0.05或P<0.01〕,且随病情加重,各指标逐渐恶化。相关分析显示,血浆Ang-2与IL-6(r=0.468,P=0.000)、CRP(r=0.492,P=0.000)、APACHEⅡ评分(r=0.560,P=0.000)、SOFA评分(r=0.508,P=0.000)、LIS评分(r=0.588,P=0.000)均呈明显正相关;与PaO2/FiO2呈明显负相关(r=-0.648,P=0.000)。对单因素分析中有统计学意义的APACHEⅡ评分、LIS评分、PaO2/FiO2、Ang-2和IL-6进行多因素logistic回归分析发现,入院时APACHEⅡ评分高〔估计值比值比(OR)=1.316,95%可信区间(95%CI)=1.040~1.633,P=0.022〕和血浆Ang-2水平升高(OR=1.287,95%CI=1.041~1.760,P=0.038)是ARDS死亡的独立危险因素。Ang-2预测ARDS的ROC曲线下面积为0.964,最佳临界值为1.79μg/L时的特异度为90.0%,敏感度为92.5%,高于APACHEⅡ评分、SOFA评分及IL-6的预测价值。结论 ARDS患者血浆Ang-2水平显著升高,可以作为肺损伤病情严重程度判断和预后评估的辅助指标。
目的:探討急性呼吸窘迫綜閤徵(ARDS)患者血管生成素2(Ang-2)的水平變化與肺損傷程度和預後的關繫及其臨床意義。方法採用前瞻性觀察性研究方法,選擇安徽醫科大學第三附屬醫院重癥醫學科2012年1月至2014年3月收治的ARDS患者53例,按ARDS柏林定義分為輕度(15例)、中度(22例)、重度(16例)3組,按28 d轉歸分為生存組(29例)和死亡組(24例)。以同期20例非ARDS患者作為對照。記錄患者入院24 h內急性生理學與慢性健康狀況評分繫統Ⅱ(APACHEⅡ)評分、序貫器官衰竭評分(SOFA)、氧閤指數(PaO2/FiO2)、肺損傷評分(LIS),檢測血漿Ang-2、白細胞介素-6(IL-6)、C-反應蛋白(CRP)水平。採用單因素和多因素logistic迴歸方法分析影響ARDS預後的危險因素;繪製受試者工作特徵麯線(ROC),評價Ang-2在預測ARDS中的價值。結果與非ARDS組比較,ARDS組APACHEⅡ、SOFA、LIS評分明顯升高, PaO2/FiO2明顯降低,病死率明顯增加,血漿Ang-2、IL-6、CRP水平明顯升高〔APACHEⅡ(分):20.7±5.0比14.1±5.3,SOFA(分):7.7±3.5比3.5±2.1,LIS(分):1.69±0.71比0.28±0.27,PaO2/FiO2(mmHg,1 mmHg=0.133 kPa):159.5±61.3比394.0±63.2,病死率:45.3%(24/53)比20.0%(4/20),Ang-2(μg/L):4.73(2.59,6.99)比1.22(0.61,1.52),IL-6(ng/L):56.50(27.15,139.90)比13.05(4.38,15.55),CRP(mg/L):95.75(41.74,189.72)比10.56(3.92,21.36),P<0.05或P<0.01〕,且隨病情加重,各指標逐漸噁化。相關分析顯示,血漿Ang-2與IL-6(r=0.468,P=0.000)、CRP(r=0.492,P=0.000)、APACHEⅡ評分(r=0.560,P=0.000)、SOFA評分(r=0.508,P=0.000)、LIS評分(r=0.588,P=0.000)均呈明顯正相關;與PaO2/FiO2呈明顯負相關(r=-0.648,P=0.000)。對單因素分析中有統計學意義的APACHEⅡ評分、LIS評分、PaO2/FiO2、Ang-2和IL-6進行多因素logistic迴歸分析髮現,入院時APACHEⅡ評分高〔估計值比值比(OR)=1.316,95%可信區間(95%CI)=1.040~1.633,P=0.022〕和血漿Ang-2水平升高(OR=1.287,95%CI=1.041~1.760,P=0.038)是ARDS死亡的獨立危險因素。Ang-2預測ARDS的ROC麯線下麵積為0.964,最佳臨界值為1.79μg/L時的特異度為90.0%,敏感度為92.5%,高于APACHEⅡ評分、SOFA評分及IL-6的預測價值。結論 ARDS患者血漿Ang-2水平顯著升高,可以作為肺損傷病情嚴重程度判斷和預後評估的輔助指標。

Objective To approach the correlation between angiopoietin-2 (Ang-2) levels and degree of lung injury and prognosis and its clinical significance in patients with acute respiratory distress syndrome (ARDS). Methods A prospective observation was conducted. Fifty-three ARDS patients admitted to Department of Critical Care Medicine of Third Affiliated Hospital of Anhui Medical University from January 2012 to March 2014 were enrolled. According to the criteria of the Berlin Definition of ARDS,the patients were divided into mild group (n=15),moderate group(n=22)and severe group(n=16). Meanwhile,ARDS patients were further divided into survival group(n=29)and non-survival group(n=24)according to 28-day outcomes. Twenty cases of non-ARDS patients were served as control. The acute physiology and chronic health evaluationⅡ(APACHEⅡ)score,sequential organ failure assessment(SOFA)score,oxygenation index(PaO2/FiO2),lung injury score(LIS)were recorded within 24 hours after admission. And the plasma levels of Ang-2,interleukin-6(IL-6)and C-reaction protein (CRP)were measured. The independent risk factors of ARDS were analyzed by univariate and multivariable logistic regression. Receiver operating characteristic curve(ROC)was plotted to evaluate the value of Ang-2 in predicting ARDS. Results Compared with non-ARDS group,APACHEⅡ score,SOFA score,LIS score,mortality were significantly increased,PaO2/FiO2 was significantly decreased,and plasma Ang-2,IL-6,CRP were significantly elevated〔APACHEⅡscore:20.7±5.0 vs. 14.1±5.3,SOFA score:7.7±3.5 vs. 3.5±2.1,LIS score:1.69±0.71 vs. 0.28±0.27,PaO2/FiO2(mmHg,1 mmHg=0.133 kPa):159.5±61.3 vs. 394.0±63.2,mortality:45.3%(24/53) vs. 20.0%(4/20),Ang-2(μg/L):4.73(2.59,6.99)vs. 1.22(0.61,1.52),IL-6(ng/L):56.50(27.15,139.90)vs. 13.05(4.38,15.55),CRP(mg/L):95.75(41.74,189.72)vs. 10.56(3.92,21.36),P<0.05 or P<0.01〕. Each index increased or decreased more significantly with the aggravation of the disease. It was shown by correlation analysis that the plasma levels of Ang-2 was significantly positive correlated with IL-6(r=0.468,P=0.000),CRP(r=0.492,P=0.000),APACHEⅡscore(r=0.560,P=0.000),SOFA score(r=0.508,P=0.000)and LIS score (r=0.588,P=0.000),significantly negatively correlated with PaO2/FiO2(r=-0.685,P=0.000). Factors, APACHEⅡ score,LIS score,PaO2/FiO2,Ang-2 and IL-6 founded statistical significance in univariate analysis were analyzed using multivariable logistic regression. High APACHEⅡscore at admission〔odds ratio(OR)=1.316, 95% confidence interval(95%CI)=1.040-1.633,P=0.022〕and increased plasma Ang-2 levels(OR=1.287, 95%CI=1.041-1.760,P=0.038)were the independent prognostic factors for the 28-day mortality in ARDS. The area under the ROC curve of Ang-2 was 0.964,the optimal critical value of Ang-2 was 1.79μg/L,the specificity was 90.0%,and sensitivity was 92.5%. Plasma levels of Ang-2 was better in predicting ARDS than APACHEⅡscore, SOFA score and IL-6. Conclusions The plasma level of Ang-2 was significantly increased in patients with ARDS. The plasma level of Ang-2 was correlated with the severity of acute lung injury and had important prognosis evaluation.
