BACKGROUND Few reports have examined the viral aetiology of fever of unknown origin (FUO). OBJECTIVE This study determined the prevalence of human herpes virus (HHV) DNA in blood of Chinese patients with classic FUO using the polymerase chain reaction (PCR) and explored the possible role of HHV. STUDY DESIGN Blood samples were collected from 186 patients (151 children, 35 adults) with class...

Abstract Human herpes virus 6 (HHV-6) is a ubiquitous and most common pathogen that affects humans. 6B (HHV-6B) wide spread human herpesvirus infects people when they are children, establishes latent infections in the central nervous system (CNS), especially hippocampus amygdala, induces neurologic diseases. HHV-6 can establish infection be reactivated by various stimuli. Recently, viral genomi...

to the editor: The case of human herpesvirus 8 (HHV-8) reported by Dagna et al. (July 14 issue)1 is considered to be distinct from HHV-8–associated multicentric Castleman’s disease owing to the absence of typical histologic findings and elevated plasma levels of interleukin-6. The histopathology of HHV-8–associated multicentric Castleman’s disease is variable, as compared with the classic descr...

Background/Aim—Human papillomaviruses (HPVs) are important, but not suYcient, for the development of cervical cancer. All three human â-herpesviruses—cytomegalovirus (CMV) and human herpesviruses (HHV) types 6 and 7—have been detected in the cervix. In addition, CMV and HHV-6 can interact with HPVs in vivo. This study examined the possible role of â-herpesviruses in cervical cancer development....

Human herpesvirus 6 (HHV-6) can activate the human immunodeficiency virus (HIV) promoter and accelerate cytopathic effects in HIV-infected human T cells. This study examines the regions of the HIV promoter required for HHV-6 transactivation in a heterogeneous population of primary human T lymphocytes with or without antigenic stimulation. Two different strains of HHV-6, GS and Z29, transactivat...

The characterization is reported of the human herpesvirus-6B (HHV-6B) rep/U94 gene, which is a homologue of the adeno-associated virus type 2 rep. In this study, a monoclonal antibody was produced against HHV-6B REP (anti-REP mAb). Immunofluorescence staining using the anti-REP mAb showed that REP was localized to the nucleus in HHV-6-infected MT4 cells. It was first detected at 24 h post-infec...

Results Of the 198 samples tested, 18 (9.09%) were positive to at least one of the three viruses, 10 (5.10%) were positive for EBV, 10 (5.10%) positive for CMV and 12 (6.10%) positive for HHV -6. According to age, we found that only those who had a less than or equal to 30 years old were infected. Infection with EBV, CMV and HHV-6 in women accounted for 8.57%, 8.57% and 11.43% respectively. Aga...

Earlier studies have shown that Kaposi sarcomas contain cells infected with human herpesvirus (HHV) 6B, and in current studies we report that both AIDSassociated and classic-sporadic Kaposi sarcoma contain HHV-7 genome sequences detectable by PCR. To determine the distribution of HHV-7-infected cells relative to those infected with HHV-6, sections from paraffin-embedded tissues were allowed to ...

Human herpesvirus 6 (HHV-6) exists as distinct variants HHV-6A and HHV-6B. The complete genomes of HHV-6A and HHV-6B have been sequenced. HHV-6B contains 97 unique genes. CD46 is the cell receptor for HHV-6, explaining its broad tissue tropism but its restricted host-species range. HHV-6 utilizes a number of strategies to down-regulate the host immune response, including molecular mimicry by pr...
