Epstein-Barr virus-associated smooth muscle tumors (EBV-SMTs) are a rare type of tumor occurring exclusively in immunocompromised patients in the setting of HIV/AIDS, post-organ transplant, and congenital immunodeficiency. These tumors require demonstration of EBV DNA on histopathologic studies in order to establish a diagnosis. The overall prognosis is good.

Post-transplant lymphoproliferative disorders (PTLD) and lymphomas in immunocompromised individuals represent significant clinical challenges, with a limited understanding of their pathogenesis. We investigated a PTLD cohort (n = 50) consisting of 'early lesions' (infectious mononucleosis-like PTLD, plasmacytic and follicular hyperplasias), polymorphic PTLD and post-transplant diffuse large B-cell lymphomas (PT-DLBCL). The study also included 15 DLBCL with autoimmune/immunocompromised backgrounds (IS-DLBCL) and 14 DLBCL, not otherwise specified (DLBCL, NOS), as control.

Introduction: Epstein-Barr virus (EBV) infection has been linked to cervical cancer (CC), but few have described the clinical and outcome features of patients with CC and EBV infection.
Methods: We conducted a single-center matched cohort study on 94 patients with CC. Real-time Polymerase chain reaction (RT-PCR) was used to detect (Epstein-Barr nuclear antigen 1) and (Latent membrane protein 1).

Genetic and environmental factors jointly determine the susceptibility to develop multiple sclerosis (MS). Improvements in the design of epidemiological studies have helped to identify consistent environmental risk associations such as the increased susceptibility for MS following Epstein-Barr virus (EBV) infection, while biological mechanisms that drive the association between EBV and MS remain incompletely understood. An increased and broadened repertoire of antibody and T-cell immune responses to EBV-encoded antigens, especially to the dominant CD4 T-cell EBV nuclear antigen 1 (EBNA1), is consistently observed in patients with MS, indicating that protective EBV-specific immune responses are deregulated in MS and potentially contribute to disease development.

Persistence is a strategy used by many viruses to evade eradication by the immune system, ensuring their permanence and transmission within the host and optimizing viral fitness. During persistence, viruses can trigger various phenomena, including target organ damage, mainly due to an inflammatory state induced by infection, as well as cell proliferation and/or immortalization. In addition to immune evasion and chronic inflammation, factors contributing to viral persistence include low-level viral replication, the accumulation of viral mutants, and, most importantly, maintenance of the viral genome and reliance on viral oncoprotein production.
