摘要:

目的 探讨脓毒症患儿降钙素原(PCT)和凝血功能指标变化及其相关性。方法 回顾性分析2021年6月—2022年6月上海儿童医学中心157例脓毒症患儿和132例非脓毒症患儿基本信息、原发病、弥漫性血管内凝血(DIC)发生率、休克发生率、序贯器官功能衰竭(SOFA)评分、28 d治疗转归等临床资料,以及PCT、凝血酶原(PT)、活化部分凝血活酶时间(APTT)、纤维蛋白原(Fib)、D-二聚体(DD)等凝血功能指标检测结果。根据PCT水平将157例脓毒症患儿分为A组(PCT<2.00 ng·mL-1)、B组(PCT为2.00~10.00 ng·mL-1)、C组(PCT≥10.00 ng·mL-1),比较3个组脓毒症患儿和非脓毒症患儿各项指标的差异。分析脓毒症患儿PCT与凝血功能指标的相关性。采用受试者工作特征(ROC)曲线评价各项指标判断脓毒症患儿预后不良的效能。结果 与非脓毒症患儿比较,脓毒症患儿PT和APTT均延长,PCT、Fib、DD水平均升高(P<0.05)。A组、B组、C组患儿PT、APTT、Fib、DD呈现逐渐增高的趋势;3个组中PCT水平越高、脓毒症越严重的患儿,预后不良所占比例越高。脓毒症患儿PT、APTT、DD、Fib与PCT均呈正相关(r值分别为0.220、0.502、0.186、0.166,P<0.05)。PCT、PT、APTT、Fib、DD判断脓毒症患儿预后不良的曲线下面积分别为0.822、0.819、0.524、0.541、0.879;PCT联合PT、APTT、Fib、DD判断脓毒症患儿预后不良的曲线下面积为0.909,且具有较好的敏感性(89.5%)和特异性(78.9%)。结论 脓毒症患儿PT、APTT、Fib、DD均与PCT相关。动态联合监测PCT和凝血功能指标判断脓毒症患儿不良预后的效能优于单项指标,可为脓毒症患儿临床诊疗方案的确定和预后评估提供参考。

Abstract:

Objective To investigate the changes of procalcitonin(PCT) and coagulation function indicators in children with sepsis and their correlation. Methods A total of 157 children with sepsis and 132 children without sepsis admitted to Shanghai Children's Medical Center from June 2021 to June 2022 were enrolled. Relevant basic information,primary disease,the incidence of disseminated or diffuse intravascular coagulation(DIC),the incidence of shock,sequential organ failure assessment(SOFA) score,the 28-day treatment outcomes of patients were recorded. PCT and coagulation function indicators [prothrombin time(PT),activated partial thromboplastin time(APTT),fibrinogen(Fib),D-dimer(DD)] were determined. According to the levels of PCT,the sepsis group was classified into 3 groups,including Group A(PCT<2.00 ng·mL-1),Group B(2.00 ng·mL-1≤ PCT <10.00 ng·mL-1) and Group C(PCT≥10.00 ng·mL-1). The differences of each indicator between the 3 groups of sepsis group and non-sepsis group were compared,and the correlation between different PCT levels and coagulation function indicators in sepsis group was analyzed. Receiver operating characteristic(ROC) curve was used to evaluate the efficiency of each indicator for the poor prognosis of children with sepsis. Results PT and APTT were prolonged in sepsis group,which had statistical significance with those in non-sepsis group(P<0.05). In sepsis group,the levels of PCT,Fib and DD were higher than those in non-sepsis group(P<0.05). The levels of PT,APTT,Fib and DD in Group A,Group B and Group C were gradually increased. The higher the PCT and the more severe sepsis were in Group A,B and C,the more patients with poor prognosis. In sepsis group,PT,APTT, Fib and DD were positively correlated with PCT level(r=0.220、0.502、0.186 and 0.166,P<0.05). The areas under curves of PCT,PT,APTT,Fib and DD were 0.822,0.819,0.524,0.541 and 0.879,respectively. The area under curve of PCT combined with PT,APTT,Fib and DD was 0.909,which had good sensitivity(89.5%) and specificity(78.9%). Conclusions There is a correlation between PT,APTT,Fib,DD and PCT in children with sepsis. The efficiency of dynamic combined monitoring of PCT and coagulation function indicators for the diagnosis and prognosis of sepsis is better than that of single indicator,which can provide a reference for the determination and prognosis of clinical diagnosis and treatment plan for children with sepsis.
