Kaposi's sarcoma (KS) is a disease characterized by proliferative vascular lesions, which almost invariably contain the KS-associated herpesvirus (KSHV), also called human herpesvirus 8. KSHV is a lymphotrophic and angiotrophic herpesvirus, whose genome encodes several proteins involved in proliferation, antiapoptotic functions, and inflammation. Most KS spindle cells express latent KSHV genes, but a few express lytic genes, which might be involved in angiogenic and paracrine mechanisms that contribute to KS pathogenesis. A number of tissue culture and mouse models have been established, but a comprehensive system that accurately portrays KS pathogenesis still does not exist.

Kaposi Sarcoma (KS) is a frequently aggressive malignancy caused by Kaposi sarcoma herpesvirus (KSHV/HHV-8). People with immunodeficiencies, including HIV, are at increased risk for developing KS, but our understanding of the contributions of the cellular genome to KS pathogenesis remains limited. To determine if there are cellular genetic alterations in KS that might provide biological or therapeutic insights, we performed whole exome sequencing on 78 KS tumors and matched normal control skin from 59 adults with KS (46 with HIV-associated KS and 13 with HIV-negative KS) receiving treatment at the Uganda Cancer Institute in Kampala, Uganda.

Background: Antiretroviral therapy (ART) restores cellular immunity, significantly reducing AIDS-related mortality and morbidity thus improving the quality of life among People living with HIV (PLHIV). Studies done in several countries show a decline in AIDS defining cancers (ADCs) with the introduction of ART however the increased longevity has led to the increase of Non-AIDS defining cancers (NADCs). The study was aimed at studying the changing spectrum and trends of cancer among Human Immunodeficiency Virus (HIV) patients in southwestern Uganda.

Background: Multimorbidity is increasingly prevalent in lower- and middle-income countries. Health-related quality of life (HRQOL) has been inversely associated with multimorbidity but is understudied in lower- and middle-income countries. We report cardiovascular disease (CVD) multimorbidity in Haiti and its association with HRQOL.

Background: Human herpesvirus-8 (HHV8) can present with cutaneous or extracutaneous manifestations. While violaceous skin lesions characterize cutaneous Kaposi sarcoma, extracutaneous HHV8 is challenging to diagnose due to nonspecific symptoms.
Objectives: We evaluated the role of microbial cell-free DNA next-generation sequencing (mcfDNA NGS) in diagnosing HHV8-related illness.
