Kaposi's sarcoma-associated herpesvirus or Human herpesvirus-8 (KSHV/HHV-8), an oncogenic human herpesvirus and the leading cause of cancer in HIV-infected individuals, is a major public health concern with recurring reports of epidemics on a global level. The early detection of KSHV virus and subsequent activation of the antiviral immune response by the host's immune system are crucial to prevent KSHV infection. The host's immune system is an evolutionary conserved system that provides the most important line of defense against invading microbial pathogens, including viruses...

Kaposi's sarcoma (KS) is a systemic neoplastic disease that can present cutaneous symptoms and is usually treated with a systematic approach due to its extent. Due to its radiosensitivity, radiotherapy is considered one of its main treatments, for palliation and local control of the skin and mucosal lesions. The aim of this paper was to report the first case of KS treated by hemi-body electron irradiation protocol in Greece. A fractionated 40 Gy hemi-body electron irradiation was prescribed to a 60-year-old male patient with KS at his legs...

Herpesviruses thymidine kinase (TK) and protein kinase (PK) allow the activation of nucleoside analogues used in anti-herpesvirus treatments. Mutations emerging in these two genes often lead to emergence of drug-resistant strains responsible for life-threatening diseases in immunocompromised populations. In this review, we analyze the binding of different nucleoside analogues to the TK active site of the three α-herpesviruses [Herpes Simplex Virus 1 and 2 (HSV-1 and HSV-2) and Varicella-Zoster Virus (VZV)] and present the impact of known mutations on the structure of the viral TKs...

OBJECTIVES: Skin cancers are one of the most common malignancies in solid-organ transplant recipients. Increased age and immunosuppressive drug use are risk factors for posttransplant skin malignancies. We evaluated nonmelanocytic skin cancer incidence and development time in transplant patients. MATERIALS AND METHODS: We reviewed 1833 patients who received kidney, liver, and heart grafts between 1996 and 2016 at Baskent University. We excluded melanocytic skin cancers, premalignant lesions, and benign skin tumors...

Solid-organ transplant recipients are at higher risk of developing Kaposi sarcoma, which is a multicentric vascular neoplasm of lymphatic endothelium-derived cells. Reducing doses of immunosuppressive drugs and switching from calcineurin inhibitors to the mammalian target of rapamycin inhibitor rapamycin have been suggested as an effective first-line treatment modality in most patients. Herein, we report a 64-year-old renal transplant recipient who developed multiple cutaneous and visceral Kaposi sarcoma lesions 2 months after transplant...

Patients following solid organ transplantation show a higher risk of developing cancer compared to the general population. Elevated risk is likely due to the interplay of a combination of factors, such as chronic inflammation, coexisting medical conditions, immunosuppressive regimen and persistent infection with oncogenic viruses. In addition, the tumor microenvironment plays a pivotal role in cancer progression, by driving recruitment and in situ differentiation of anti-inflammatory cells of the adaptive and innate immune system such as regulatory T cells, Th17, Dendritic Cells, Myeloid Derived Suppressor Cells, Type 2 Macrophages...

An important component of lytic infection by Kaposi's sarcoma-associated herpesvirus (KSHV) is the ability of the virus to evade the innate immune response, specifically type I interferon (IFN) responses that are triggered by recognition of viral nucleic acids. Inhibition of type I IFN responses by the virus promotes viral replication. Here we report that KSHV uses a caspase-dependent mechanism to block type I IFN, in particular IFNβ, responses during lytic infection. Inhibition of caspases during KSHV reactivation resulted in increased TBK1/IKKϵ-dependent phosphorylation of IRF3 as well as elevated levels of IFNβ transcription and secretion...

Kaposi's Sarcoma (KS) is a malignancy that generally effects the skin, and can be systemic with internal organ involvement. It originates from the vascular endothelium. KS's relationship with human immunodeficiency virus (HIV) infection is well known. Isolated scrotal KS in the urogenital system is quite rare and scrotal KS in an HIV-negative patient is limited to a few cases. In this case report, the biopsy result from the violescent nodular lesions on the scrotum of the HIV-negative 81-year-old patient was found compatible with KS and a pathology was not detected in the systemic screening...

Kaposi sarcoma (KS) of the head and neck area is uncommon with limited published case series. Our routine and consultation files were reviewed for histologically and immunohistochemically proven KS affecting any cutaneous or mucosal head and neck site. Ten males and one female aged 42-78 years (median, 51 years; mean, 52 years) were retrieved. Eight patients were HIV-positive and three were HIV-negative. The affected sites were skin (n = 5), oral/oropharyngeal mucosa (n = 5), and lymph nodes (n = 3) in variable combination...

Kaposi's sarcoma-associated herpesvirus (KSHV) is one of the few oncogenic human viruses known to date. Its large genome encodes more than 85 proteins and includes both unique viral proteins as well as proteins conserved amongst herpesviruses. KSHV ORF20 is a member of the herpesviral core UL24 family, but the function of ORF20 and its role in the viral life cycle is not well understood. ORF20 encodes three largely uncharacterized isoforms, which we found were localized predominantly in the nuclei and nucleoli...

HIV infection can be manifested with different skin symptoms, which are sometimes considered infection markers. Erythrodermic psoriasis is a possible manifestation, which is a widespread form of psoriasis. We report a clinical case of a young man suspected of HIV infection due to a psoriatic erythroderma confirmed by biopsies, associated with Kaposi sarcoma. Afterwards, HIV infection was confirmed by serological tests. Antiretroviral therapy was started, with positive response at one month of treatment. Erythrodermic psoriasis can be considered a skin marker of HIV infection when occurs in previously healthy patients or in recalcitrant psoriasis...

The human γ-herpesviruses Epstein-Barr virus (EBV or HHV4) and Kaposi sarcoma-associated herpesvirus (KSHV or HHV8) are each associated with around 2% of all tumors in humans worldwide. However, investigations into their infection, oncogenesis, and immune responses that protect from the associated tumors have been hampered by the exclusive tropism of these pathogens for humans. Mice with reconstituted human immune system components (HIS mice) provide the unique opportunity to study persistent infection, virus associated lymphoma formation, and cell-mediated immune control of EBV and KSHV...

BACKGROUND: This paper focuses on the collision of three factors: a growing emphasis on sharing research through open access publication, an increasing awareness of big data and its potential uses, and an engaged public interested in the privacy and confidentiality of their personal health information. One conceptual space where this collision is brought into sharp relief is with the open availability of patient medical photographs from peer-reviewed journal articles in the search results of online image databases such as Google Images...

Viruses must exploit the cellular biosynthetic machinery and evade cellular defense systems to complete their life cycles. Due to their crucial roles in cellular bioenergetics, apoptosis, innate immunity and redox balance, mitochondria are important functional targets of many viruses, including tumor viruses. The present review describes the interactions between mitochondria and proteins coded by the human tumor viruses human T-cell leukemia virus type 1, Epstein-Barr virus, Kaposi's sarcoma-associated herpesvirus, human hepatitis viruses B and C, and human papillomavirus, and highlights how these interactions contribute to viral replication, persistence and transformation...

Human immunodeficiency virus (HIV) causes impairment to the human immune system which leads to immunocompromised conditions, including ocular complications. Several important HIV-associated disorders may involve the anterior segment, ocular surface, and adnexae organ such as dry eye, blepharitis which reduce quality of life of patients. In present, potent antiretroviral therapies HAART (highly active antiretroviral therapy) has improved the length and quality of life which may lead to an increased prevalence of anterior segment ocular disorders...

PURPOSE OF REVIEW: Adults living with HIV have an increased risk of malignancy yet there is little data for adolescents and young adults. We reviewed recently published cancer epidemiology, treatment, and outcome data for adolescents and young adults living with HIV (AYALHIV) aged 10 to less than 25 years between 2016 and 2017. RECENT FINDINGS: AYALHIV are at increased risk of developing cancer compared to their uninfected peers. Kaposi sarcoma and non-Hodgkin lymphoma occur most frequently with variation by geographical region...
