摘要:

目的 探讨凝血指标在恶性肿瘤患者合并细菌性血流感染(BSI)诊断和预后评估中的价值。方法 选取2019年1月—2023年12月复旦大学附属肿瘤医院恶性肿瘤合并BSI住院患者206例(阳性组)和未合并BSI恶性肿瘤住院患者238例(对照组)。收集患者基础信息、病原菌感染情况、凝血功能检测结果等临床资料。对阳性组患者进行随访,根据其预后情况分为预后良好组(162例)和预后不良组(44例)。采用多因素Logistic回归分析评估恶性肿瘤患者发生BSI的影响因素。采用受试者工作特征(ROC)曲线评价凝血指标对恶性肿瘤合并BSI的诊断效能。结果 阳性组凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、凝血酶时间(TT)、纤维蛋白原(Fib)、D-二聚体(DD)、纤维蛋白(原)降解产物(FDP)均高于对照组(P<0.05)。PT、TT、Fib、DD、FDP是恶性肿瘤患者发生BSI的危险因素(P<0.05)。PT、TT、Fib、DD、FDP单项检测和5项指标联合检测诊断恶性肿瘤患者发生BSI的曲线下面积分别为0.814、0.608、0.596、0.784、0.771、0.879。预后不良组年龄、PT、APTT、TT高于预后良好组(P<0.05),Fib低于预后良好组(P<0.001)。结论 PT、TT、Fib、DD、FDP可用于辅助诊断恶性肿瘤患者BSI,5项指标联合检测诊断效能更优。PT、APTT、TT、Fib与恶性肿瘤合并BSI患者的预后有一定关系。

Abstract:

Objective To investigate the diagnostic and prognostic value of coagulation indicators in patients with malignant tumors complicated with bacterial bloodstream infection (BSI). Methods A total of 206 patients with malignant tumors complicated with BSI (positive group) and 238 patients with malignant tumors without BSI (control group) admitted to Fudan University Shanghai Cancer Center from January 2019 to December 2023 were enrolled. Basic information,pathogen infection status and coagulation function determination results of the patients were collected. The positive group patients were followed up and classified into good prognosis group (162 cases) and poor prognosis group (44 cases) based on their prognosis. Multivariate Logistic regression analysis was used to evaluate the influencing factors of BSI in patients with malignant tumors. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficacy of coagulation indicators for BSI in patients with malignant tumors. Results Prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time (TT),fibrinogen (Fib),D-dimer (DD),and fibrin (fibrinogen) degradation product (FDP) in the positive group were higher than those in the control group (P<0.05). PT,TT,Fib,DD and FDP were risk factors for BSI in patients with malignant tumors (P<0.05). The areas under curves of PT,TT,Fib,DD,FDP single and combined determinations for the diagnosis of BSI in patients with malignant tumors were 0.814,0.608,0.596,0.784,0.771 and 0.879,respectively. The age,PT,APTT and TT in poor prognosis group were higher than those in good prognosis group(P<0.001),and Fib was lower than that in good prognosis group (P<0.001). Conclusions PT,TT,Fib,DD and FDP can be used to assist in the diagnosis of BSI in patients with malignant tumors,and the combined determination of the 5 indicators has better diagnostic efficacy. PT,APTT,TT and Fib are related to the prognosis of patients with malignant tumors complicated with BSI.
