AIDS-related cancer diseases are malignancies with low incidence on healthy people that affect mostly subjects already immunocompromised. The connection between HIV/AIDS and these cancers has not been established yet, but a weakened immune system is certainly the main cause. We envisaged the possibility to screen a small library of compounds synthesized in our laboratory against opportunistic tumors mainly due to HIV infection like Burkitt's Lymphoma. From cellular assays and gene expression analysis we identified two promising compounds...

With combined antiretroviral therapy (cART), the risk for HIV-infected individuals to develop a non-Hodgkin lymphoma is diminished. However, the incidence of Burkitt lymphoma (BL) remains strikingly elevated. Most BL present a t(8;14) chromosomal translocation which must take place at a time of spatial proximity between the translocation partners. The two partner genes, MYC and IGH, were found colocalized only very rarely in the nuclei of normal peripheral blood B-cells examined using 3D-FISH while circulating B-cells from HIV-infected individuals whose exhibited consistently elevated levels of MYC-IGH colocalization...

BACKGROUND: Human Immuno-deficiency Virus (HIV) associated non-Hodgkin's lymphoma (NHL) was a special group of disease, which manifests distinct clinical features and prognosis as compared with NHLs in patients without HIV. We performed this study to describe the clinical features of the disease and investigated the potential prognostic factors. METHODS: HIV-infected patients who were newly diagnosed with NHL were enrolled in this study. The selection of anti-lymphoma treatment regimen was mainly dependent on the pathological subtypes of NHLs...

About one-half of all Burkitt lymphoma (BL) patients are younger than 40 years, and one-third belong to the adolescent and young adult (AYA) subset, defined by an age between 15 and 25-40 years, based on selection criteria used in different reports. BL is an aggressive B-cell neoplasm displaying highly characteristic clinico-diagnostic features, the biologic hallmark of which is a translocation involving immunoglobulin and c-MYC genes. It presents as sporadic, endemic, or epidemic disease. Endemicity is pathogenetically linked to an imbalance of the immune system which occurs in African children infected by malaria parasites and Epstein-Barr virus, while the epidemic form strictly follows the pattern of infection by HIV...

Background: Highly active antiretroviral therapy (HAART) has extended the life expectancy of patients with HIV/AIDS to approach that of the general population. However, it remains unclear whether HIV infection affects the survival of patients with lymphoma in the HAART era.Methods: Patients diagnosed with Hodgkin lymphoma, diffuse large B-cell lymphoma (DLBCL), Burkitt lymphoma, peripheral T-cell lymphoma (PTCL), or follicular lymphoma during 2004-2011 were identified from the National Cancer Database. Survival analyses were conducted, where each HIV-infected patient was propensity score matched to a HIV-uninfected patient on the basis of demographic factors, clinical features, and treatment characteristics...

Rituximab is the first monoclonal antibody to be approved for use by the US Food and Drug Administration in cancer. Its role in the treatment of non-Hodgkin lymphoma, including chronic lymphocytic leukaemia (CLL), has evolved significantly. We aimed to systematically review and update the literature on rituximab in lymphoma and CLL, and provide evidence-based consensus guidelines for its rational use. Validated methodology from the Cancer Care Ontario Program in Evidence-based Care was used. A comprehensive literature search was completed by a methodologist from the Hematology Disease Site Group of Cancer Care Ontario...

Burkitt lymphoma (BL) is >90% EBV-associated when this pediatric cancer is diagnosed in regions heavily burden by endemic Plasmodium falciparum malaria and thus has been geographically classified as endemic BL. The incidence of endemic BL is 10-fold higher compared to BL diagnosed in non-malarious regions of the world. The other forms of BL have been classified as sporadic BL which contain EBV in ∼30% of cases and immunodeficiency BL which occurs in HIV-infected adults with ∼40% of tumors containing EBV...

BACKGROUND: Most malignant lymphomas in HIV-patients are caused by reactivation of EBV-infection. Some lymphomas have a very rapid fulminant course. HHV-8 has also been reported to be a cause of lymphoma. The role of CMV in the development of lymphoma is not clear, though both CMV and HHV-8 have been reported in tissues adjacent to the tumour in Burkitt lymphoma patients. Here we present a patient with asymptomatic HIV infection, that contracted a primary cytomegalovirus (CMV) infection and human herpes virus 8 (HHV-8) infection...

BACKGROUND Non-neoplastic causes such as infections and thrombi account for most intracardiac masses. Primary tumors such as myxomas and metastasis from breast cancer, lung cancer, or melanomas account for many of the remaining cases. Burkitt lymphoma manifesting as an intracardiac mass is a rare entity, with 21 cases reported in the English literature. CASE REPORT We report the case of a man infected with human immunodeficiency virus (HIV) who presented with non-specific cardiac symptoms and was later found to have intracardiac mass caused by Burkitt lymphoma...

BACKGROUND: The human immunodeficiency virus (HIV) epidemic has strongly influenced non-Hodgkin lymphoma (NHL) incidence in the U.S. general population, but its effects on NHL mortality trends are unknown. METHODS: Using SEER cancer registry data, we assessed NHL mortality rates in the United States (2005-2012) and mapped NHL deaths to prior incident cases. Data included HIV status at NHL diagnosis. We describe the proportion of NHL deaths linked to an HIV-infected case, for 3 AIDS-defining subtypes [diffuse large B-cell lymphoma (DLBCL), Burkitt lymphoma, and central nervous system (CNS) lymphoma] and within demographic categories...

Immune Reconstitution Syndrome (IRIS) has been associated with a variety of infections in patients with human immunodeficiency virus (HIV). However, we are reporting the first case of IRIS secondary to Rhodococcus equi (R. equi) in a patient with HIV. We report the case of a 48-year-old male found to have HIV infection in the setting of Burkitt's lymphoma. While on anti-retroviral therapy and chemotherapy, he had developed IRIS secondary to R. equi that manifested as a cavitating pneumonia. This report outlines the successful management of the R...

Cardiac masses are rare, the differential diagnosis includes infections with vegetations or abscesses, neoplasms, thrombi, and structural abnormalities. A pathology specimen is essential in therapeutic strategy planning for a cardiac mass, also if the primary imaging findings look dramatic at the start. Even in an inoperable setting, a life-saving therapy might be available. We report a case of a 49-year-old man, known with HIV-1, who was several times admitted with pericarditis. Now he was hospitalized with progressive lower limb edema, atrial fibrillation and detection of a giant cardiac mass in left and right atrium with infiltration of surrounding tissues...
