A 60-year-old HIV-1 infected woman on antiretroviral therapy (emtricitabine/tenofovir, and ritonavir-boosted atazanavir) developed Hodgkin's lymphoma. The patient initiated ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine) chemotherapy and presented with neutropenia and severe hypokalemia. Hypokalemia was considered as part of a proximal tubular renal dysfunction, and other causes of hypokalemia were excluded. Due to suspicion of drug--drug interactions between antiretrovirals and vinblastine, ritonavir-boosted atazanavir was switched to dolutegravir and the patient continued emtricitabine/tenofovir...

Several lines of evidence support the concept that NK cells play an important role in control of hepatitis C virus (HCV) infection via cytokine secretion and cytotoxicity. IL-7 is a homeostatic cytokine with a role in T cell development, activation, proliferation, and cytokine secretion. The IL-7Rα chain [cluster of differentiation (CD)127] is expressed on NK cells, with greatest abundance on the CD56(bright)CD16(dim/-) (CD56(bright)) subset. Here, we measured CD127 expression on CD56(bright), CD56(dim)CD16(+) (CD56(dim)), or CD56(neg)CD16(+) (CD56(neg)) NK cell subsets of 25 uninfected donors (UD); 34 chronic HCV-infected, treatment-naïve; 25 HIV-infected, virally suppressed on antiretroviral therapy (ART); and 42 HCV-HIV-coinfected subjects on ART...

Background: Primary effusion lymphoma (PEL) is a Kaposi's sarcoma herpes virus (KSHV)-induced lymphoma that typically arises in body cavities of HIV-infected patients. PEL cells are often co-infected with Epstein-Barr virus (EBV). "PEL-like" lymphoma is a KSHV-unrelated lymphoma that arises in body cavities of HIV-negative patients. "PEL-like" lymphoma is sometimes EBV positive. The derivation of PEL/"PEL-like" cells is unclear. Methods: Mesothelial cells were cultured from body cavity effusions of 23 patients...

Malignant lymphomas form a heterogeneous group of neoplasms of the lymphoid tissue with different clinical courses, depending on the treatment and the prognosis. Human immunodeficiency virus (HIV) infection and acquired immune deficiency syndrome (AIDS) have been associated with an increased risk for the development of lymphoproliferative disorders. The incidence of lymphoma is associated with 60-fold increase in seropositive patients as compared to seronegative patients. The present case describes a diffuse aggressive extranodal lymphoma in a known HIV patient...

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening disorders. The incidences, mortality and cost of SJS and TEN in US adults are not well-characterized. We analyzed data from the 2009-2012 Nationwide Inpatient Sample, containing a representative 20% sample of all hospitalizations in the US. SJS, SJS/TEN and TEN were identified by a validated algorithm using ICD-9- CM codes. The mean incidences of SJS, SJS/TEN and TEN were 9.3, 1.6, and 1.9 per million people per year, respectively...

Plasmablastic lymphoma, a rare highly aggressive non-Hodgkin's lymphoma subtype, often associated with HIV infection, is a close differential diagnosis of plasmablastic myeloma. The 2 conditions may be morphologically and immunophenotypically identical. However, differentiating between the 2 conditions is critical for adequate patient management. Herein, we describe an unusual case of plasmablastic myeloma with biclonal gammopathy which was initially diagnosed as plasmablastic lymphoma based on lymph node biopsy and immunohistochemistry (IHC) results...

The association of mycosis fungoides and kaposi's sarcoma in HIV-negative patients is a rare phenomenon. The presence of human herpesvirus 8 (HHV-8) - associated with all forms of Kaposi's sarcoma - has also been recently identified in mycosis fungoides lesions. However, a causal association between HHV-8 and the onset of mycosis fungoides has not been established yet. The present case reports a patient who developed Kaposi's sarcoma lesions after a two-year UVB phototherapy to treat a mycosis fungoides. Negative immunohistochemistry staining for Kaposi's sarcoma-associated herpesvirus in the initial mycosis fungoides lesions strengthens the absence of a link between Kaposi's sarcoma-associated herpesvirus and mycosis fungoides...

BACKGROUND: Early diagnosis of HIV associated lymphoma is challenging because the definitive diagnostic procedure of biopsy, requires skills and equipment that are not readily available. As a consequence, diagnosis may be delayed increasing the risk of mortality. We set out to determine the frequency and risk factors associated with the misdiagnosis of HIV associated lymphoma as tuberculosis (TB) among patients attending the Uganda Cancer Institute (UCI). METHODS: A retrospective cohort study design was used among HIV patients with associated lymphoma patients attending the UCI, Kampala, Uganda between February and March 2015...

Acquired immune deficiency syndrome (AIDS)-related lymphomas (ARL) still represent a relevant field of clinical research. For most histological subtypes of ARL, no optimal initial therapy has been clearly defined so far. Rituximab plus chemotherapy is feasible and effective and should be offered to all patients with CD20-positive ARL regardless of their CD4 cell count. Combination antiretroviral therapy (cART) should be given concomitantly with chemotherapy, bearing in mind potential drug-drug interactions...

T follicular helper cells (TFh) are key components of the adaptive immune system; they are primarily found in germinal centers (GCs) where their interaction with B cells supports humoral immune responses and efficient antibody production. They are defined by the expression of CXC receptor 5, program death-1, ICOS, and secretion of IL-21. Their differentiation is regulated by B-cell lymphoma 6. The relationship and function of circulating TFh to bona fide TFh resident in the GC is much debated. HIV infection impacts the TFh response with evidence of aberrant TFh function observed in acute and chronic infection...

Successful treatment of HIV associated multicentric Castleman`s disease (HIV+MCD) with rituximab based approaches has dramatically improved survival and reduced the risk of HHV8-associated lymphoma. Longer term outcomes including relapse rates have not been described and are important to establish the potential role of maintenance therapy. A prospective cohort of 84 patients with biopsy proven HIV+MCD were treated with risk stratified rituximab based therapy. Four patients (5%) died from refractory HIV+MCD and 80 achieved clinical remission...

Primary effusion lymphoma (PEL) is a rare type of non-Hodgkin's lymphoma presenting as a lymphomatous effusion and absence of a solid tumor mass. Extracavitary PEL (EC-PEL) is a subtype of PEL with the absence of an effusion but presence of solid tumor. PEL and EC-PEL share the same histopathologic and immunophenotypic features. Kaposi sarcoma-associated herpesvirus (KSHV) positivity is seen universally in these malignancies and is a requisite for diagnosis. Most cases are seen to occur in HIV positive individuals...

HIV-associated lipoatrophy (LA) has considerable implications for risk of metabolic diseases, quality of life, and adherence to treatments. Although it has decreased in high-income countries, it is still very common in resource-limited countries. Understanding the pathophysiological mechanisms of LA can open the possibility to explore new ways to treat or prevent this condition. To identify new markers for an accurate and quick diagnosis will be also of interest. Thus, we aimed to examine functional classes of genes implicated in LA and to identify potential new markers for an accurate/quick diagnosis of LA and future complications...

Background: Plasmablastic lymphoma (PBL), initially described in 1997 in the oral cavity of HIV positive patients, is now recognized as a distinct aggressive and rare entity of diffuse large B-cells lymphoma by the World Health Organization (WHO) classification. Since the original description, others cases have been reported. However, these are largely derived from case reports or small series limiting any definitive conclusions on clinical characteristics and outcome. Patients and methods: The clinical, biological, pathological features and outcome of a cohort including 135 patients with PBL, from LYSA centers in France and Belgium, were reported and analyzed...

Human T-cell lymphotropic virus type 1 (HTLV-1) is a retrovirus which is endemic to certain regions of the world and infects around 10-20 million people. HTLV-1 is the etiologic agent of Adult T cell leukemia/lymphoma and HTLV-1 associated neurological disorders including mainly HTLV-1 associated myelopathy/Tropical spastic paraparesis. The involvement of the central nervous diseases occurs among: HTLV-1 infected patients from endemic areas, HIV positive individuals and drug users. The ability of HTLV-1 to cause associated neuropathies starts with the virus crossing the blood brain barrier (BBB), then entering and infecting the cells of the central nervous system...
