摘要

目的　通过检测EB病毒(EBV)感染患儿CD163水平, 探讨CD163在EBV相关噬血细胞综合征(HLH)的诊断、病情监测及预后中的意义。方法　将因不同感染就诊的94例患儿分为EBV阳性组(n=55)和EBV阴性组(n=39, 对照组), 进一步将EBV阳性患儿分为传染性单核细胞增多症(IM)组(n=47)和HLH组(n=8)。应用酶联免疫法检测血清可溶性CD63(sCD163)水平; 流式细胞术检测外周血单核细胞表面CD163表达率。结果　HLH患儿血清sCD163水平均>10 000 ng/mL, 其中3例>30 000 ng/mL; HLH组患儿血清sCD163水平远高于对照组和IM组(P<0.05)。EBV阳性患儿血清sCD163水平与EBV-DNA拷贝数、乳酸脱氢酶和血清铁蛋白水平呈正相关, 与白细胞计数、中性粒细胞计数、血红蛋白和血小板计数呈负相关(P<0.05)。HLH患儿sCD163水平在治疗后逐步下降, 但随病情反复又升高。结论 EBV感染患儿的CD163水平与临床严重程度密切相关, sCD163>10 000 ng/mL的EBV感染患儿需警惕并发HLH。

Abstract

Objective To study the clinical significance of CD163 in the diagnosis and the evaluation of severity and prognosis of childhood hemophagocytic lymphohistiocytosis (HLH). Methods Ninety-four children were classifieied into Epstein-Barr virus (EBV)-positive (n=55) and EBV-negative groups (n=39; control group). The EBV-positive group was subgrouped into infectious mononucleosis (IM; n=47) and HLH (n=8). Serum levels of soluble CD163 were measured using ELISA. Expression of CD163 on mononuclear cells was detected by flow cytometry. Results The serum levels of soluble CD163 were > 10 000 ng/mL in all eight HLH patients (> 30 000 ng/mL in 3 cases). The mean serum levels of soluble CD163 in the HLH group were significantly higher than in the control and IM groups (P<0.05). The serum levels of soluble CD163 in EBV-positive children were positively correlated with EBV-DNA copies and serum levels of ferritin and LDH, but were negatively correlated with white blood cell count, neutrophil count, hemoglobin and platelet count. The follow-up after treatment for three HLH patients showed that serum levels of soluble CD163 were significantly reduced, but the soluble CD163 levels rebounded in one patient who was complicated by fungal pneumonia infection. Conclusions The levels of serum soluble CD163 may be related to the severity in children with HLH. The EBV-positive children with soluble CD163 levels >10 000 ng/mL should be considered the possibility of HLH.
