目的 探讨血浆可溶性晚期糖基化终末产物受体对急性呼吸窘迫综合征诊断的价值及预后意义.方法 本研究为前瞻性病例对照研究,将201 1年2月至2012年9月东南大学附属第二医院重症监护病房（ICU）收治的43例符合2012年急性呼吸窘迫综合征柏林定义及诊断标准患者,根据急性呼吸窘迫综合征柏林定义的患者氧合状态分为轻、中、重度三组,同时收集无肺损伤的住院患者20例作为对照组,根据28 d转归将急性呼吸窘迫综合征组分为生存组和死亡组两个亚组.入院24h内测定血常规、血气分析、血生化、C反应蛋白（CRP）,记录最高体温（T）,进行急性生理学与慢性健康状况评分系统Ⅱ（APACHEⅡ）评分、序贯器官衰竭估计（SOFA）评分;采用酶联免疫吸附法（ELISA）检测可溶性晚期糖基化终末产物受体水平.采用SPSS 17.0统计分析软件进行数据处理.计量资料采用方差或Mann-Whitney U检验,计数资料比较采用x2检验;绘制受试者工作特征曲线（ROC）.结果 急性呼吸窘迫综合征组患者血浆可溶性晚期糖基化终末产物受体浓度均显著高于无肺损伤组[377 （286.3 ～ 548.0）pg/ml]（P均＜0.05）,中、重度急性呼吸窘迫综合征组[分别为3188（1984～ 3042）,3273 （3170～3265） pg/ml]患者的可溶性晚期糖基化终末产物受体水平高于轻度急性呼吸窘迫综合征组[1707（1649～ 1870） pg/ml] （P ＜0.05）;死亡组可溶性晚期糖基化终末产物受体浓度[2996（2768～3319）pg/ml]明显高于生存组[2147（1965 ～ 2449） pg/ml],有统计学意义;可溶性晚期糖基化终末产物受体诊断急性呼吸窘迫综合征的ROC曲线下面积为0.912,以842 pg/ml为截断值,灵敏度为92.7％,特异度为87.8％,优于CRP.结论 血浆可溶性晚期糖基化终末产物受体水平对急性呼吸窘迫综合征诊断有一定价值,高浓度的可溶性晚期糖基化终末产物受体与急性呼吸窘迫综合征不良预后相关.     

KDIGO标准APACHEⅡ与SOFA评分对脓毒症急性肾损伤患者的预后评估

目的 探讨急性肾损伤国际指南(KDIGO)制定的急性肾损伤(AKI)诊断分期标准、急性生理与慢性健康状况评分Ⅱ(APACHEⅡ)和序贯器官衰竭评估(SOFA)评分对脓毒症AKI患者的预后评估价值.方法 前瞻收集2012-03-01 ～2013-03-01期间在我院ICU接受治疗的脓毒症患者的临床资料,采用KDIGO标准对脓毒症患者进行AKI诊断和分期;根据患者入ICU第1个24h内的生理指标最差值进行APACHEⅡ和SOFA评分,并用受试者工作特征(ROC)曲线评估3项系统对预后评估的准确性.以Logistic多元回归分析对预后的影响.结果 共280例脓毒症患者,占同期ICU住院患者的41.7％ (280/670),总体院内死亡率为29.8％.脓毒症肾损伤168例,占脓毒症患者的60％,其中1期76例,死亡率22.4％;2期48例,死亡率37.5％;3期44例,死亡率72.7％.脓毒症肾损伤患者的APACHEⅡ及SOFA评分均高于非AKI患者(P＜0.05).Logistic多元回归分析显示,APACHEⅡ评分＞22分(OR =4.50),KDIGO分期1、2、3期(OR值分别为2.31、7.44、45.00)是脓毒症并AKI患者院内死亡的独立预测指标.结论 KDIGO诊断标准与APACHEⅡ、SOFA评分对脓毒症肾损伤患者整体预后都有较好的预测价值.     

脓毒症患者血清可溶性髓系细胞表达的触发受体-1水平及与预后的关系

Objective To approach the relationship between the contents of soluble form of triggering receptor expressed on myeloid cells-1 (sTREM-1) and prognosis in patients with sepsis. Methods Using prospective, control study design, a total of 50 patients with sepsis who were admitted in intensive care unit (ICU) of the Second Hospital of Tianjin Medical University from March to December in the year of 2009 were enrolled. Firstly, the patients were divided into sepsis (n=28) and severe sepsis (n=22) groups according to the patients' condition. Then the patients were divided into survival group (n = 34) and death group (n = 16)according to the clinical outcome at 28 days after onset of sepsis. Clinical and laboratory data including blood routine tests, blood chemistry, blood gas analysis, C-reactive protein (CRP) and procalcitonin (PCT) were collected on the 1st, 3rd and 7th day after onset. Acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ ) score was determined. sTREM-1 levels were determined using enzyme linked immunosorbent assay (ELISA) method. Correlation analysis of the sTREM-1, APACHE I score, white blood cell count (WBC) and CRP, using Logistic regression analysis. A total of 30 healthy persons were enrolled into the control group. Results The sTREM-1 levels (ng/L) in 50 septic patients on the 1st day were higher than those of the healthy persons (52. 80±9. 30 vs. 23. 29±6. 22, P＜0. 01). The sTREM-1 levels (ng/L) in severe sepsis group on the 1st, 3rd and 7th day (58. 25±10. 59, 65. 75±13. 57, 50.18±21. 73) were higher than those of the sepsis group (48.55±5.20, 42.85±8.54, 34.02±12.86, P＜0.05 or P＜0.01). The sTREM-1 levels (ng/L) of the survival group on the 1st, 3rd and 7th day (53. 07± 10. 47, 45. 04±9. 89,32. 84 ±8. 42) were decreased with the progression of the ailment. The sTREM-1 levels did not differ significantly between the control group and survival group on the 7th day (P＞0. 05). The sTREM-1 levels (ng/L) in the death group on the 1st, 3rd and 7th day were increased with the progression of the ailment (52.27±6.42, 69.67±12.83, 75. 70± 10. 55), and the level was significantly higher than that in survival group on the 3rd and 7th day (both P＜0. 01). The contents of sTREM-1 were positive correlated with APACHE Ⅱ score (r= 0.657, P＜0. 01), but not correlated with WBC (r= 0.023, P＞0. 05), whilesomewhat correlated with CRP (r=0. 150, P＜0.10). Logistic regression analysis showed that sTREM-1 [odds ratio (OR) = 0. 893,P = 0. 000] and APACHE I score (OR = 0.771, P = 0.000) might be potential prognostic factors for septic patients. The area under the receiver operator characteristic curve was 0. 868 and 0.930. The sensitivity of prognostic evaluation was 81.1% and specificity was 74.5% with sTREM-1 50 ng/L, and the sensitivity was 83. 8% and specificity was 86. 3% with APACHE Ⅱ score 20 to estimate the outcome. Conclusion The serum sTREM-1 are elevated at early stage in sepsis patients. It can reflect the severity of the condition. The sTREM-1 level, which might be considered as a potential prognostic factor for septic patients, is significantly correlated with APACHE Ⅱ score.
