First detected by Chang et al. (1994) in Kaposi sarcomas associated with the acquired immune deficiency syndrome (AIDS) (see IARC, 1996) by representational difference analysis, this virus was termed Kaposi-sarcoma-associated herpesvirus, KSHV. KSHV is also associated with primary effusion lymphoma and some cases of multicentric Castleman disease (see Section 2). In keeping with the systematic ...

Primary effusion lymphoma (PEL) is a unique clinicopathological entity associated with human herpesvirus-8 (HHV-8) infection, occurring almost exclusively in human immunodeficiency virus (HIV)-infected individuals. We report a rare case of HHV-8-negative PEL in an HIV-negative elderly patient who presented with pleural effusion. The patient was treated with CHOP and Rituximab. As opposed to the...
AIMS Human herpesvirus 8 (HHV-8) has been identified in multicentric Castleman's disease and in angioimmunoblastic lymphadenopathies. However, the presence of the virus does not necessarily indicate an aetiological role in these conditions. This study investigates the cell types infected by HHV-8 in Castleman's disease and examines the correlation between HHV-8 and Castleman's disease lymph nod...
Human herpesvirus 6 variant A (HHV-6A) and human herpesvirus 6 variant B (HHV-6B) are two closely related yet distinct viruses. These visuses belong to the Roseolovirus genus of the betaherpesvirus subfamily; they are most closely related to human herpesvirus 7 and then to human cytomegalovirus. Over 95% of people older than 2 years of age are seropositive for either or both HHV-6 variants, and...
BACKGROUND The seroprevalence of Kaposi sarcoma-associated herpesvirus (KSHV)/human herpesvirus 8 (HHV-8) in sub-Saharan Africa suggests that multiple routes of transmission exist. In the present study, we examined 2 possible routes of mother-to-child transmission, through breast milk and saliva, during the first 6 months after delivery. METHODS The prevalence of HHV-8 DNA in the breast-milk ...
To elucidate the mode of human herpesvirus 8 (HHV-8) transmission in a population of Amsterdam drug users, HHV-8 seroprevalence and seroincidence were determined in 1179 drug users in the Amsterdam Cohort Studies (1985-1996). Risk factors for HHV-8 infection were examined. Serum samples were screened with an enzyme immunoassay by using HHV-8 lytic capsid (open-reading frame [ORF] 65) and latent...
The impact of cytomegalovirus, a member of the beta-herpesvirus subgroup of the Herpesviridae, on patients who have undergone transplantation cannot be overstated. However, in the last 15 years, 2 additional members of the human beta-herpesvirus family have been discovered: human herpesviruses 6 and 7 (HHV-6 and HHV-7). The impact of HHV-6 and HHV-7 is assessed, as is the well-being of transpla...
Acetylcholinesterase (AChE) and human herpesvirus type 8 (HHV-8) antigens were studied in tissue sections from 56 squamous cell carcinomas (SCC) and five retinoblastomas (Rb). Approximately 62.5% of SCC and 80% of Rb showed positive staining for AChE. AChE staining in tumors was much higher than in normal control tissue. However, only 21.4% of SCC and 60% of Rb contained HHV-8 antigens. Of the ...
