【摘要】 目的:探討中性粒细胞CD64、PCT、CRP对重症手足口病(hand,foot and mouth disease,HFMD)早期诊断的临床意义。方法:回顾性分析2017年1月-2020年11月佛山市南海区人民医院收治的110例HFMD患儿的诊疗情况,其中重症患儿40例、轻症患儿70例,所有患儿均在入院第1天测定中性粒细胞CD64、降钙素原(PCT)、C反应蛋白(CRP)、肠道病毒71型(EV71)和柯萨奇病毒A16(CA16)。分析患儿CD64、CRP、PCT检测临床诊断效能,并比较两组患儿CD64、CRP、PCT水平以及EV71和CA16的感染情况。结果:CD64灵敏度、特异度、阳性预测值、阴性预测值、均高于CPR和PCT(P<0.05);重症组患儿CD64、CRP、PCT水平分别为(15.38±3.19)MFI、(23.67±3.04)mg/L、(12.37±0.18)ng/mL,均高于轻症组的(10.46±2.33)MFI,(11.47±2.11)mg/L、(5.84±0.09)ng/mL(P<0.05);重症组患儿EV71阳性率高达87.50%,高于轻症组24.28%(P<0.05);重症组患儿CA16阳性率为22.50%,与轻症组18.57%比较,差异无统计学意义(P>0.05)。结论:CD64、CRP、PCT和EV71在重症手足口病患儿中具有诊断价值,可作为重症手足口病的常规检查项目,有助于筛查可疑的重症手足口病。

[Abstract] Objective: To explore the clinical significance of neutrophil CD64, procalcitonin (PCT), C-reactive protein (CRP) in the early diagnosis of severe hand, foot and mouth disease (HFMD). Method: A retrospective analysis of the diagnosis and treatment of 110 children with HFMD admitted to the People’s Hospital of Nanhai District, Foshan City from January 2017 to November 2020. 40 were severely ill children and 70 were mildly ill children. On the first day of admission, neutrophil CD64, PCT, CRP, enterovirus 71 (EV71) and Coxsackie virus A16 (CA16) were measured. The clinical diagnostic efficacy of CD64, CRP and PCT was analyzed, and the levels of CD64, CRP and PCT as well as the infection of EV71 and CA16 were compared between the two groups. Result: The sensitivity, specificity, positive predictive value, negative predictive value of CD64 were higher than those of CPR and PCT (P<0.05); the levels of CD64, CRP and PCT in severe group were (15.38±3.19) MFI, (23.67±3.04) mg/L and (12.37±0.18) ng/mL, respectively, which were higher than (10.46±2.33) MFI, (11.47±2.11) mg/L, (5.84±0.09) ng/mL in mild group (P<0.05); the positive rate of EV71 in the severe group was 87.50%, which was higher than 24.28% in the mild group (P<0.05); the positive rate of CA16 in the severe group was 22.50%, compared with 18.57% in the mild group, there was no significant difference (P>0.05). Conclusion: CD64, CRP, PCT and EV71 have diagnostic value in children with severe HFMD, and can be used as routine examination items for severe HFMD, which can help to screen suspected severe HFMD.

手足口病(hand,foot and mouth disease,HFMD)是目前儿科最常见的一种急性传染病,是以手、足、口腔、臀部等部位出现斑丘疹或者疱疹为主要特征的疾病,有时膝关节以及肘关节出现皮疹,可能伴有发热症状。其主要的传染途径是粪、口传播或亲密接触,好发于夏季[1-2]。5岁及以下的婴幼儿常多发,传染性强,短时间内可形成局部流行现象。该病多数患儿预后良好,一般情况下可在7 d左右恢复,但少数病情严重的患儿容易出现脑膜炎、心肌炎、神经源肺水肿[3-4]。重症病例早期无特异性检查,临床表现不典型,病情进展迅速,一旦出现肺水肿、肺出血等引发心肺功能衰竭,会在短时间内死亡[5]。……
