amyotrophic lateral sclerosis is a progressive neurodegenerative disease with uncertain etiology. for many years, viruses have been suspected as causative agents. there are conflicting reports about the possible role of viruses such as human herpes virus 8 (hhv8) and retroviruses in the pathogenesis of the sporadic amyotrophic lateral sclerosis. we conducted a prospective case-control study to ...

BACKGROUND Human herpesvirus 8 (HHV8)-positive plasmablastic lymphoma is a disease which correlates with acquired immunodeficiency syndrome (AIDS). Little is known about the pathogenesis of the disease due to its rarity. We report an autopsy case about AIDS related HHV-8-positive plasmablastic lymphoma and presents an examination about HHV8 related proteins for the disease by using immunohistoc...

background and objective: it is presumed that human herpes virus 8 (hhv-8) is the necessary cause of all different forms of kaposi’s sarcoma which is the most common neoplasm in hiv-infected persons. in this study, we wanted to determine the prevalence of hhv8 infection in all the available isfahan (central iran) hiv positive individuals in comparison with healthy blood donor, and also investig...

The etiologic role of the recently discovered Kaposi’s sarcoma (KS)associated herpesvirus (KSHV), also called human herpesvirus 8 (HHV8), in the development of all types of KS is now generally accepted (1,2). Long before the epidemic of the acquired immunodeficiency disease syndrome (AIDS) began, East Africa was known as a highrisk area for KS. For example, during the quinquennium 1964 through ...

BACKGROUND The outcome of Kaposi sarcoma varies. While many patients do well on highly active antiretroviral therapy, others have progressive disease and need chemotherapy. In order to predict which patients are at risk of unfavorable evolution, we established a prognostic score. METHOD The survival analysis (Kaplan-Meier method; Cox proportional hazards models) of 144 patients with Kaposi sa...

Abstract L'association Kaposi–myélome multiple est extrêmement rare. Nous rapportons, le cas d'un patient âgé de 76 ans suivi dans notre formation pour un myélome à immunoglobuline A kappa stade III-B selon Durie et Salmon. Ceci a été associé à des lésions cutanées dont la biopsie cutanée était en faveur d’une maladie de Kaposi. La sérologie de l’herpès virus humain de type 8 (HHV8) est revenue...

Kaposi's sarcoma (KS) associated with HHV8 is one of the common connective tissue malignancies especially in immunocompromised patients. The aim of the present study was to determine the common HHV8 genotypes in hospitalized patients in Tehran, Iran. A total of 36 archival paraffin-embedded KS tissue samples of patients with common characterization of KS were collected between 1999 to 2010 from...

Kaposi’s sarcoma has emerged from being a rarity to being the most important neoplasm in many sub-Saharan countries. Most investigators involved in Kaposi’s sarcoma research now agree that the gammaherpesvirus human herpesvirus 8 (HHV8), also called Kaposi’s sarcoma-associated herpesvirus (KSHV), is central in the pathogenesis of this disease (1,2). Molecular and seroepidemiologic studies (3,4)...

BACKGROUND Kaposi's sarcoma (KS) is an angioproliferative disorder associated with human herpesvirus 8 infection. Classic KS is the most prevalent type of KS in countries of the Mediterranean basin including Egypt. Several in vitro studies have detected c-kit expression in AIDS related-KS however, only a few studies addressed this issue in the classic type with no data on the ethnicity of studi...

Primary effusion lymphoma (PEL) is a human herpes virus 8 (HHV8)-positive large B-cell neoplasm that presents as an effusion with no detectable tumor in individuals with human immunodeficiency virus infection or other immune deficiencies. PEL is an aggressive neoplasm with a poor prognosis. PEL cells show diverse morphologies, ranging from immunoblastic or plasmablastic to anaplastic. The immun...
