Among 164 individuals in a rural population of Cambodia, antibodies to human herpesvirus-8 (HHV-8) were found among 56.6% of the women and 50.6% of the men. Seropositivity for HHV-8 tended to decrease with age (P < 0.001) and was not associated with exposure to hepatitis B virus (HBV) or HCV. Human herpesvirus-8, which shows a high rate of infection during childhood, does not seem to have the same pattern of transmission as HBV. This suggests very early acquisition of infection with HHV-8 in Cambodia.

Primary effusion lymphoma (PEL) is an HIV-associated B-cell non-Hodgkin lymphoma (NHL) caused by Kaposi sarcoma herpesvirus (KSHV). There is no validated prognostic model in PEL, and prognosis is thought to be poor compared to other HIV-associated NHL. We derived the PEL-Prognostic score (PEL-PS) from an international real-world training set of 59 patients with HIV-associated PEL who received first-line anthracycline-containing chemotherapy from the HIV and AIDS Malignancy Branch at the National Cancer Institute (NCI) in the United States and the National Center for HIV Malignancy at the Chelsea and Westminster Hospital (CWH) in England from 2000 to 2022.

The cell cycle is governed by kinase activity that coordinates progression through a series of regulatory checkpoints, preventing the division of damaged cells. The Kaposi's sarcoma-associated herpesvirus (KSHV) encodes multiple genes that modulate or co-opt the activity of these kinases, shaping the cellular environment to promote viral persistence. By advancing the cell cycle, KSHV facilitates latent replication and subsequent transmission of viral genomes to daughter cells, while also contributing to the establishment of multiple cancer types.

Castleman disease (CD) is a rare hematologic disorder characterized by pathologic lymph node changes and a range of symptoms due to excessive cytokine production. While uncontrolled infection with human herpesvirus-8 (HHV-8) is responsible for the cytokine storm in a portion of multicentric CD (HHV-8-associated MCD) cases, the etiology of unicentric CD (UCD) and HHV-8-negative/idiopathic MCD (iMCD) is unknown. Several hypotheses have been proposed regarding the pathogenesis of UCD and iMCD, including occult infection given the precedent established by HHV-8 infection.

Introduction: Infections significantly impact morbidity and mortality in lung transplant (LuTx) recipients. This survey focused on documenting current practices regarding the prevention and management of infections in LuTx in Italy.
Methods: A 52-question survey was administered online in the period from December 1, 2023, to January 31, 2024, assessing center characteristics, Tx team organization, microbiological investigations, infection prevention, and management.

Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (KSHV), which are the only members of the gamma(γ) herpesviruses, are oncogenic viruses that significantly contribute to the development of various human cancers, such as Burkitt's lymphoma, nasopharyngeal carcinoma, Hodgkin's lymphoma, Kaposi's sarcoma, and primary effusion lymphoma. Oncogenesis triggered by γ-herpesviruses involves complex interactions between viral genetics, host cellular mechanisms, and immune evasion strategies. At the genetic level, crucial viral oncogenes participate in the disruption of cell signaling, leading to uncontrolled proliferation and inhibition of apoptosis.
