可溶性白细胞分化抗原14在脓毒症中的研究进展

脓毒症、严重脓毒症和脓毒症休克是急诊科经常处理的疾病,有很高的病死率,早期诊断是提高生存率的关键因素之一。近几年,降钙素原被用作诊断脓毒症患者的生物学标记物,尽管它与感染密切相关,但是特异性有限,在发生全身炎症反应综合征时会升高。可溶性白细胞分化抗原14(sCD14-st,又称presepsin)是一种存在于单核细胞/巨噬细胞中的糖蛋白。初步报道显示脓毒症患者体内的sCD14-st水平比健康者体内的sCD14-st显著升高。

Usefulness of presepsin (sCD14-ST) measurements as a marker for the diagnosis and severity of sepsis that satisfied diagnostic criteria of systemic inflammatory response syndrome

CD14 is present in macrophage, monocyte, and granulocyte cells and their cell membranes, and it is said to be responsible for intracellular transduction of endotoxin signals. Its soluble fraction is present in blood and is thought to be produced in association with infections. It is called the soluble CD14-subtype (sCD14-ST), and in the following text it is referred to by its generic name, presepsin. We have previously reported that presepsin is produced in association with infection and that it is specifically expressed in sepsis. In the present study we developed a new rapid diagnostic method by using a chemiluminescent enzyme immunoassay that allowed making automated measurements in a shorter time. The results of using this method to measure presepsin values in different pathological conditions were normal, 294.2 ± 121.4 pg/ml; local infection, 721.0 ± 611.3 pg/ml; systemic inflammatory response syndrome, 333.5 ± 130.6 pg/ml; sepsis, 817.9 ± 572.7 pg/ml; and severe sepsis, 1,992.9 ± 1509.2 pg/ml; the presepsin values were significantly higher in patients with local infection, sepsis, and severe sepsis than in patients who did not have infection as a complication. In a comparative study with other diagnostic markers of sepsis based on ROC curves, the area under the curve (AUC) of presepsin was 0.845, and greater than the AUC of procalcitonin (PCT, 0.652), C-reactive protein (CRP, 0.815), or interleukin 6 (IL-6, 0.672). In addition, a significant correlation was found between the APACHE II scores, an index of disease severity, and the presepsin values, suggesting that presepsin values can serve as a parameter that closely reflects the pathology.     

血浆可溶性髓样细胞触发受体-1对脓毒症早期诊断的价值及预后意义

目的 探讨血浆可溶性髓样细胞触发受体-1(soluble triggering receptor expressed on myeloid cells-1,sTREM-1)对脓毒症早期诊断的价值及预后意义。方法 采用前瞻性病例对照研究。将2009年5月至2010年6月天津医科大学第二医院重症监护病房( ICU)收治的56例系统性炎症反应综合征(SIRS)患者,根据2001年国际脓毒症会议诊断标准分为脓毒症组32例、SIRS组24例,同时收集非SIRS患者25例作为对照组,根据28 d转归将脓毒症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、降钙素原（PCT）、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;采用酶联免疫吸附法(ELISA)检测sTREM-1水平。采用SPSS 16.0统计分析软件进行数据处理,计量资料采用方差或Kruskal-Wallis H检验,相关性分析采用Spearman相关系数。结果 血浆sTREM-1水平脓毒症组高于SIRS组及对照组[分别为250.9 (195.8 ～ 354.3) ng/L、103.6(89.4～166.2)ng/L、33.6 (26.2 ～43.0) ng/L,P＜0.01],死亡组高于生存组[分别为360.5 (262.2 ～434.5)ng/L、204.1（175.0～269.6）ng/L,P＜0.01];脓毒症组患者血浆sTREM-1水平与APACHEⅡ评分呈正相关(r,=0.426,P=0.032);sTREM-1 ROC曲线下面积为0.935,高于PCT、CRP。结论 血浆sTREM-1水平对脓毒症早期诊断有一定意义,早期sTREM-1水平升高与不良预后相关。     

Usefulness of presepsin (sCD14 subtype) measurements as a new marker for the diagnosis and prediction of disease severity of sepsis in the Korean population

Purpose

Presepsin has recently emerged as a new useful sepsis marker, and our study is focused on the usefulness of presepsin as earlier detection and monitoring biomarker for sepsis comparing with other conventional biomarkers.

Materials and methods

We compared the mean values of presepsin, procalcitonin, interleukin 6, and high-sensitivity C-reactive protein levels between infection group and noninfection group of study subjects and assessed whether the values decreased during treatment. Furthemore, we evaluated the diagnostic accuracy of presepsin in sepsis and compared the mean level of presepsin to the Acute Physiology and Chronic Health Evaluation III score and mortality rate on the 30th day.

Results

Mean presepsin levels were significantly different between infection group and noninfection group (1403.47 pg/mL vs 239.00 pg/mL). During treatment, mean levels of presepsin decreased significantly, and in the receiver operating characteristic curve analysis, the area under curve value of presepsin was significantly higher than that of other biomarkers. The presepsin levels did not correlate significantly with Acute Physiology and Chronic Health Evaluation III scores and mortality rates on the 30th day.

Conclusions

Presepsin showed significantly higher values in infection group than in noninfection group. The diagnostic accuracy of presepsin was higher than other conventional biomarkers. For early diagnosis and treatment of bacterial sepsis, presepsin could be a more useful marker than the other markers.     

The utility of presepsin in diagnosis and risk stratification for the emergency patients with sepsis

Objectives

To evaluate the value of presepsin in diagnosis and risk stratification of septic patients in emergency department, and investigate the utility in differentiation of gram-positive and gram-negative bacterial infection.

Usefulness of presepsin in the diagnosis of sepsis in a multicenter prospective study

The clinical usefulness of presepsin for discriminating between bacterial and nonbacterial infections (including systemic inflammatory response syndrome) was studied and compared with procalcitonin (PCT) and interleukin-6 (IL-6) in a multicenter prospective study. Suspected sepsis patients (n = 207) were enrolled into the study. Presepsin levels in patients with systemic bacterial infection and localized bacterial infection were significantly higher than in those with nonbacterial infections. In addition, presepsin, PCT, and IL-6 levels in patients with bacterial infectious disease were significantly higher than in those with nonbacterial infectious disease (P < 0.0001, P < 0.0001, and P < 0.0001, respectively). The area under the receiver operating characteristic curve was 0.908 for presepsin, 0.905 for PCT, and 0.825 for IL-6 in patients with bacterial infectious disease and those with nonbacterial infectious disease. The cutoff value of presepsin for discrimination of bacterial and nonbacterial infectious diseases was determined to be 600 pg/ml, of which the clinical sensitivity and specificity were 87.8 % and 81.4 %, respectively. Presepsin levels did not differ significantly between patients with gram-positive and gram-negative bacterial infections. The sensitivity of blood culture was 35.4 %; that for presepsin was 91.9 %. Also there were no significant differences in presepsin levels between the blood culture-positive and -negative groups. Consequently, presepsin is useful for the diagnosis of sepsis, and it is superior to conventional markers and blood culture.
