Clinical Cross Sectional Study of Herpes Simplex Virus Infection of Central Nervous System in Newborn Infants / 实用儿科临床杂志

ABSTRACT

Objective To investigate the prevalence of herpes simplex virus(HSV) infection of central nervous system(CNS) in newborn infant,and analyze its clinical characteristics.Methods Cerebrospinal fluid(CSF) was collected from 40 acute viral infection of central nervous system who were hospitalized during June 2001 to June 2002.Polymerse chain reacton techniques(nested-PCR)was used to detect HSVspecific DNA in CSF,enzyme-linked immunosorbert assays(ELISA)was applied to detect HSV-specific IgM and IgG antibody in CSF and serum specimens.Results Two cases of neonatal patients were HSV-1 DNA PCR positive in CSF,both(mo)-ther were normal during pregnancy without a history of genital herpes.Clinical presentations of one case belonged to disseminated HSV infections and the other was limited to CNS infections.HSV-2 DNA PCR of 40 cases of neonatal patients were negative in CSF.Conclusions The rate of HSV neonatal CNS infection was 5% among viral neonatal CNS infections.HSV type 1 in the period,which showed that HSV type 1 may be the common type of HSV neonatal CNS infections.The result seems to be related to low prevalence for HSV-2(among) pregnancy women in China.
