Background and Objectives: Meningoencephalitis in Iranian children is frequent, but encephalitis is rare .The frequency of HHV-6 and HHV-7 in central nervous system diseases of our children is unclear. The aim of this study was searching the DNA-s of HHV-6 & HHV-7 in CSF samples of children with meningoencephalitis Materials and Methods: A cross sectional study (2007-2009) was done in Pediatr...
Introduction & Objective: The role and frequency of HHV-6 and HHV-7 in central nervous system (CNS) diseases of our children are unclear. The aim of this study was to search for the presence of HHV-6 & HHV-7 DNA-s in CSF samples in children with meningoencephalitis. Materials & Methods: In a cross- sectional study (2007-2009) done in the pediatric ward in Hazrat Rasoul hospital, Tehran...
Introduction: Febrile seizure is a common disorder in children with an unknown etiology. Viral infection such as herpes virus type 6 (HHV-6) has been suggested. The aim of this study was to investigate the frequency of HHV-6 infection among children with febrile seizure who had referred to Bandar Abbas children hospital. Methods: A cross-sectional study conducted between 118 children aged 6 mon...
multiple sclerosis (ms) is defined by the presence of inflammatory demyelinating plaques in the central nervous system (cns). it has been indicated that human herpes virus 6 (hhv-6) may play role in pathogenesis of ms. background: the aim of this study was to determine the presence of hhv-6 dna and anti hhv-6 igg in ms patients and controls. methods: blood samples from 59 patients with ms and 5...
An independent strain (JI) of human herpesvirus 7 (HHV-7) was isolated from a patient with chronic fatigue syndrome (CFS). No significant association could be established by seroepidemiology between HHV-7 and CFS. HHV-7 is a T-lymphotropic virus, infecting CD4+ and CD8+ primary lymphocytes. HHV-7 can also infect SUP-T1, an immature T-cell line, with variable success. Southern blot analysis with...
Introduction: During the past few years, an increasing body of evidence has suggested a possible role for human herpes virus 6 (HHV-6) in Multiple Sclerosis (MS) pathogenesis. Despite the many reports supporting the relationship between HHV-6 and MS, this association has not been definitely proved or refuted, and the matter remains unresolved. The current study was aimed to investigate any rela...
Abstract Background and Aims: Multiple sclerosis (MS) is defined by the presence of inflammatory demyelinating plaques in the central nervous system (CNS). It has been indicated that human herpes virus 6 (HHV-6) may play role in pathogenesis of MS. The aim of this study was to determine the presence of HHV-6 DNA and anti HHV-6 IgG in MS patients and controls. Materials and Methods: Bloo...
BACKGROUND Human herpesviruses 6 and 7 (HHV-6, HHV-7) are ubiquitous, with primary infection occurring early in life followed by persistence, which may involve neural tissue. While HHV-6 and HHV-7 are predominantly T lymphotropic, the extent of tissue tropism in persistent infection is not known. AIM To investigate neuropersistence and the role of HHV-6 and HHV-7 in brain tumorigenesis. MET...
