Objective: To evaluate the early diagnostic value of various indicators in the simplified JSTH score criteria for sepsis-associated disseminated intravascular coagulation (DIC). Methods: A retrospective study was conducted. Patients admitted to Intensive Care Unit (ICU) of the Second Affiliated Hospital of Kunming Medical University from January in 2017 to December in 2018 were enrolled. Totally of 365 patients were recruited, with 224 males and 132 females. The simplified JSTH score criteria was used to diagnose DIC. The patients were divided into sepsis with DIC group and sepsis without DIC group according to the diagnostic criteria of sepsis. Platelet (PLT), fibrin degradation products (FDPs), prothrombin time (PT), antithrombin (AT), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scores, sequential organ failure assessment (SOFA) scores and the simplified JSTH scores were recorded on the first ICU day. Correlation analyses were conducted.Receiver operating characteristic (ROC) curves for diagnosis of DIC with each indicator were drawn to evaluate the diagnostic efficiency and predictive ability of 28-day mortality. Results: According to the simplified JSTH score, 143 cases of sepsis complicated with DIC were diagnosed. There were significant differences in PLT, FDP, AT, PT, APACHE Ⅱ score, SOFA score, 28-day mortality rate between the two groups (all P<0.01). It was shown by Pearson correlation analysis that the criteria has the best correlation with APACHEⅡ score and SOFA score (r=0.496 and 0.612, both P<0.01). The correlation between PLT and APACHE Ⅱ score or SOFA score was the best (r=-0.440 or-0.568, both P<0.01). It was shown by ROC curve that area under ROC curve (AUC) of PLT was 0.933, and the sensitivity and specificity was 93.0% and 85.0%, respectively. The 28-day mortality was predicted by using the indicators in the criteria. The AUG of AT was 0.813, and both the sensitivity (81.6%) and specificity (73.6%) were the highest. Conclusions: The simplified JSTH score criteria can be used for early diagnosis of sepsis-associated DIC and it is positively correlated with the severity of the disease. The correlation between PLT and the severity of disease is the best, and early diagnosis efficiency of PLT is the strongest. AT has a good predictive value for 28-day mortality.
目的： 评价简化JSTH评分标准中各指标对脓毒症弥漫性血管内凝血（DIC）的早期诊断价值。 方法： 回顾性分析2017年1月至2018年12月在昆明医科大学第二附属医院入重症监护病房（ICU）即确诊为脓毒症的356例患者的临床资料，其中男224例，女132例。使用简化JSTH评分诊断DIC，根据脓毒症诊断标准将患者分为脓毒症合并DIC组及脓毒症未合并DIC组。收集患者入ICU当日血小板（PLT）、纤维蛋白（原）降解产物（FDP）、凝血酶原时间（PT）和抗凝血酶（AT）等信息，将上述指标与急性生理与慢性健康状况评分Ⅱ（APACHEⅡ评分）、序贯器官衰竭评分（SOFA评分）做相关性分析。绘制受试者工作特征（ROC）曲线，计算各指标与DIC诊断及预测28 d病死率的敏感度与特异度。 结果： 根据简化JSTH评分，诊断出脓毒症合并DIC共143例，其PLT、FDP、AT、PT、APACHEⅡ评分、SOFA评分、28 d病死率与非合并DIC组均存在显著差异，差异有统计学意义（均P<0.01）。简化JSTH评分与APACHEⅡ、SOFA评分均有显著相关性（r=0.496、0.612，均P<0.01），PLT与APACHEⅡ评分及SOFA评分相关性最好（r=-0.440、-0.568，均P<0.05）。简化JSTH评分中各指标诊断脓毒症DIC效能评价，PLT的ROC曲线下面积（AUG）为0.933，而其敏感度93.0%，特异度85.0%。简化JSTH中各指标预测脓毒症28 d病死率，AT的AUG为0.813，且敏感度（81.6%）及特异度（73.6%）均为最高。 结论： 简化JSTH评分标准可用于脓毒症DIC的早期诊断，且与疾病严重程度呈正相关；该标准中PLT与疾病严重程度相关性最好，且其早期诊断效能最强；AT对28 d病死率预测价值较好。.
