病毒是儿童脑(膜)炎发病的重要病原体,为全面了解脑(膜)炎儿童脑脊液中的病毒感染情况,采集2019年6月-2019年9月复旦大学附属儿科医院26例病毒性脑(膜)炎(Viral encephalitis and meningitis,VEVM)儿童脑脊液标本,通过两种核酸检测方法进行病毒检测。病毒宏基因组测序检测到小RNA病毒科(Picornaviridae,82.42%)、浓病毒亚科(Densovirinae,9.07%)、指环病毒科(Anelloviridae,3.21%)、圆环病毒科(Circoviridae,0.85%)、星状病毒科(Astroviridae,0.76%)和小双节RNA病毒科(Picobirnaviridae,0.38%),通过聚合酶链式反应(Polymerase chain reaction,PCR)检测到肠道病毒(Enterovirus,EV)、单纯疱疹病毒1型(Herpes simplex virus,HSV-1)、人单纯疱疹病毒4型(Epstein-Barr virus,EBV)及腮腺炎病毒(Mumps virus,MuV),检出率分别为42.31%、7.69%、7.69%和3.85%。本研究初步明确了26例VEVM儿童脑脊液病毒信息,为深入研究其病原学进化分析奠定了基础。
Abstract：Viruses are the main pathogens in children suffering from encephalitis or meningitis. We wished to achieve comprehensive understanding of virus infection in the cerebrospinal fluid(CSF) of children with encephalitis and meningitis. Hence,26 specimens of CSF among children with viral encephalitis and viral meningitis(VEVM)were collected from June 2019 to September 2019 in the Children's Hospital of Fudan University,China. Virus detection was conducted by two testing methods for nucleic acids. Viral metagenomics were used to detect Picornaviridae(82.42%),Densovirinae(9.07%),Anelloviridae(3.21%),Circoviridae(0.85%),Astroviridae(0.76%) and Picobirnaviridae(0.38%). Polymerase chain reactions were used to detect enteroviruses(EVs),Herpes simplex virus-1,Epstein-Barr virus and Mumps virus,and the detection rate was 42.31%,7.69%,7.69% and 3.85%,respectively. This study provides initial evidence of viral infection in CSF among 26 children with VEVM. Our study lays a foundation for further understanding of virus evolution.
