138例兒童傳染性單核細(xì)胞增多癥臨床特征分析摘要：

目的：探討兒童傳染性單核細(xì)胞增多癥（infectiousmononucleosis，簡(jiǎn)稱(chēng)IM）的臨床特征。

方法：回顧性分析了138例確診的IM患兒的臨床資料。

結(jié)果：138例IM患兒中男性占51.4%，年齡在3-14歲之間。主要癥狀為咽痛、發(fā)熱、淋巴結(jié)腫大和疲乏。嚴(yán)重病例在發(fā)作初期的疲乏程度和淋巴結(jié)腫大程度上顯著高于輕度病例。實(shí)驗(yàn)室檢查表現(xiàn)為白細(xì)胞計(jì)數(shù)增多、淋巴細(xì)胞比例增高和異形淋巴細(xì)胞出現(xiàn)。EB病毒抗體檢測(cè)為陽(yáng)性，且EB病毒DNA檢測(cè)陽(yáng)性。

結(jié)論：IM在兒童中多見(jiàn)，好發(fā)于3-14歲男童。臨床特征主要表現(xiàn)為咽痛、發(fā)熱、淋巴結(jié)腫大和疲乏。較為嚴(yán)重的病例在發(fā)作初期的疲乏程度和淋巴結(jié)腫大程度上顯著高于輕度病例。診斷時(shí)需重視EB病毒抗體和EB病毒DNA檢測(cè)結(jié)果。

Objective:Toinvestigatetheclinicalcharacteristicsofpediatricinfectiousmononucleosis(IM).

Methods:Aretrospectiveanalysiswasperformedontheclinicaldataof138confirmedIMchildren.

Results:Amongthe138casesofIM,malesaccountedfor51.4%,andtheagerangedfrom3to14years.Themainsymptomsweresorethroat,fever,lymphadenopathy,andfatigue.Severecaseshadsignificantlyhigherlevelsoffatigueandlymphadenopathyatonsetthanmildcases.Laboratoryexaminationshowedanincreaseinwhitebloodcellcount,anincreaseinthelymphocyteratio,andtheappearanceofatypicallymphocytes.EBvirusantibodydetectionwaspositive,andEBvirusDNAdetectionwaspositive.

Conclusion:IMismorecommoninchildren,andoccursmostlyinboysaged3-14years.Theclinicalcharacteristicsaremainlymanifestedassorethroat,fever,lymphadenopathy,andfatigue.Severecaseshavesignificantlyhigherlevelsoffatigueandlymphadenopathyatonsetthanmildcases.AttentionshouldbepaidtotheresultsofEBvirusantibodyandEBvirusDNAdetectioninthediagnosis.
