The study aims to compare two aspects concerning the diagnosis of acquired immune deficiency syndrome (AIDS)-associated central nervous system (CNS) pathology (neuroAIDS): clinical diagnoses issued ante mortem with pathology results issued post mortem. The group of 39 human immunodeficiency virus (HIV)-positive patients was created over 23 years and is limited by marked heterogeneity. The enrolled cases were treated at the "Prof. Dr. Matei Bals" National Institute for Infectious Diseases, Bucharest, Romania, deceased due to AIDS-related complications and underwent brain necropsies performed in the Pathology Laboratory at the "Colentina" Clinical Hospital, Bucharest...

Cutaneous T-cell lymphoma (CTCL) is the most frequently encountered type of skin lymphoma in humans. CTCL encompasses multiple variants, but the most common types are mycosis fungoides (MF) and Sezary syndrome (SS). While most cases of MF run a mild course over a period of many years, other subtypes of CTCL are very aggressive. The rapidly expanding fields of proteomics and genomics have not only helped increase knowledge concerning the carcinogenesis and tumor biology of CTCL but also led to the discovery of novel markers for targeted therapy...

Syndecan-1 is a heparan sulfate proteoglycan (HSPG) commonly upregulated in AIDS-related B lymphoid malignancies. Tat is the main HIV-1 transactivating factor that has a major role in the pathogenesis of AIDS-related lymphomas (ARL) by engaging heparan sulfate proteoglycans (HSPGs), chemokine receptors and integrins at the lymphoid cell (LC) surface. Here B-lymphoid Namalwa cell clones that do not express or overexpress syndecan-1 (EV-Ncs and SYN-Ncs, respectively) were compared for their responsiveness with Tat: in the absence of syndecan-1, Tat induces a limited EV-Nc migration via C-X-C motif chemokine receptor 4 (CXCR4), G-proteins and Rac...

Burkitt's lymphoma (BL) is an aggressive B-cell non-Hodgkin's lymphoma and one of the fastest growing tumors in humans. It is an acquired immunodeficiency syndrome- (AIDS-) defining disease and occurs with relatively preserved CD4 cell counts. It rarely affects the orbital region in the setting of AIDS. We report unusual presentation of a fatal case of AIDS-associated BL in a 42-year-old female patient with severe CD4 cell depletion who presented with dramatic fast growing (within days) bilateral orbital masses leading to striking facial deformities...

Clonality studies greatly assist in the diagnosis of challenging haematopathology cases. These robust and standardised tests aid the detection of clonal lymphoid populations and may assist in lymphocyte subtyping. In this case report, a gentleman presented with a high-grade transformation of a B cell neoplasm which histologically and immunophenotypically mimicked a T cell anaplastic large-cell lymphoma. With the aid of T cell and B cell receptor clonality studies, it was demonstrated that this tumour was in fact of B cell lineage...

Plasmablastic lymphoma is a rare entity accounting for around 2.7% of all AIDS-related lymphomas. The oral cavity and gastrointestinal tract are the most common sites involved. We report a case of a 34-year-old HIV-positive woman with a rare presentation of cutaneous nodules all over the body. Due to overwhelming tumour burden, she developed tumour lysis syndrome during her hospital stay and succumbed to the illness.

Kaposi's sarcoma-associated herpesvirus (KSHV) is a Gammaherpesvirus that causes acute infection and establishes life-long latency. KSHV causes several human cancers, including Kaposi's sarcoma, an acquired immune deficiency syndrome (AIDS)-related form of non-Hodgkin lymphoma. Genipin, an aglycone derived from geniposide found in Gardenia jasminoides, is known to be an excellent natural cross-linker, strong apoptosis inducer, and antiviral agent. Although evidence suggests antiviral activity of genipin in several in vitro viral infection systems, no inhibitory effect of genipin on KSHV infection has been reported...

Classically, the HIV/AIDS-related lymphomas are of the B cell type and involve the central nervous system and the abdominal cavity. Primary maxillary sinus lymphoma is rare. Plasmablastic lymphoma (PBL) is an aggressive form of non-Hodgkinvs lymphoma, and is extremely rare. Here we present a case of plasmablastic lymphoma with primary site being maxillary sinus, a rare location.

OBJECTIVES: Examining the spatial patterns of diffuse large B-cell lymphoma (DLBCL) incidence and residential proximity to toxic release locations may provide insight regarding environmental and sociodemographic risk factors. METHODS: We linked and geocoded cancer incidence data for the period 1999-2008 from the Georgia Comprehensive Cancer Registry with population data from the US Census and the Environmental Protection Agency's Toxics Release Inventory. We conducted cluster analyses and constructed Poisson regression models to assess DLBCL incidence as a function of mean distance to the toxic release sites...

BACKGROUND: MicroRNAs, small non-coding RNAs involved in gene regulation, are implicated in lymphomagenesis. We evaluated whether genetic variations in microRNA coding regions, binding sites, or biogenesis genes (collectively referred to as miRNA-SNPs) were associated with risk of AIDS-associated non-Hodgkin lymphoma (AIDS-NHL), and serum levels of four lymphoma-related microRNAs. METHODS: Twenty-five miRNA-SNPs were genotyped in 180 AIDS-NHL cases and 529 HIV-infected matched controls from the Multicenter AIDS Cohort Study (MACS), and real-time polymerase chain reaction was used to quantify serum microRNA levels...

: Lipoxins are host anti-inflammatory molecules that play a vital role in restoring tissue homeostasis. The efficacy of lipoxins and their analog epilipoxins in treating inflammation and its associated diseases has been well documented. Kaposi's sarcoma (KS) and primary effusion lymphoma (PEL) are two well-known inflammation related diseases caused by Kaposi's sarcoma-associated herpesvirus (KSHV). Controlling inflammation is one of the strategies adopted to treat KS and PEL, a primary motivation for exploring and evaluating the therapeutic potential of using lipoxins...

A 29-year-old male with acquired immunodeficiency syndrome presented with a week of left eye blurriness, which then progressed to complete vision loss. On exam, the left pupil was nonreactive to light, and fundoscopy showed significant optic nerve edema. CT and MRI of the left orbit showed a mass lesion compressing the posterior aspect of the sclera with diffuse thickening and contrast enhancement of the retrobulbar portion of the left optic nerve. The lesion demonstrated low T1 and intermediate T2 intensities and heterogeneous contrast enhancement and measured 17...

Plasmablastic lymphoma (PBL) is a rare AIDS-related malignancy with a poor prognosis. Little is known about this entity, and no standard treatment regimen has been defined. To establish an adequate treatment strategy, we investigated 24 cases of PBL arising in human immunodeficiency virus-positive individuals. Most of the patients were in the AIDS stage, with a median CD4 count of 67.5/µL. Lymph nodes (58 %), gastrointestinal tract (42 %), bone marrow (39 %), oral cavity (38 %), and CNS (18 %) were the most commonly involved sites...

BACKGROUND: Older patients with diffuse large B-cell lymphoma (DLBCL) are at risk of severe chemotherapy-related morbidity and mortality. Our objective was to quantify the risk and identify factors associated with death during the first cycle of immunochemotherapy in this population. PATIENTS AND METHODS: Using Medicare claims linked to the population-based SEER registry (SEER-Medicare), we studied patients with DLBCL aged 65 years and older who received immunochemotherapy containing rituximab, cyclophosphamide, and vincristine, in combination with doxorubicin, mitoxantrone, or etoposide in 2003-2012...

BACKGROUND: The optimal therapeutic approach for patients with AIDS-related primary central nervous system lymphoma (AR-PCNSL) remains undefined. While its incidence declined substantially with combination antiretroviral therapy (cART), AR-PCNSL remains a highly aggressive neoplasm for which whole brain radiotherapy (WBRT) is considered a standard first-line intervention. METHODS: To identify therapy-related factors associated with favorable survival, we first retrospectively analyzed outcomes of AR-PCNSL patients treated at San Francisco General Hospital, a public hospital with a long history of dedicated care for patients with HIV and AIDS-related malignancies...

PURPOSE OF REVIEW: The era of modern HIV therapeutics is well underway. The cancer and infectious disease epidemiology of HIV disease has markedly altered as populations are availed to the benefits of antiretroviral therapy (ARV). The types of cancers occurring among those with HIV infection has broadened but the case burden in absolute numbers is very low relative to the background population. There are fewer incident cases of the AIDS-defining cancers (aggressive B-cell lymphomas, Kaposi's sarcoma, and cervical cancer)...
