OBJECTIVE: HIV-infected individuals (HIVI) are threatened by meningococcal infection and presented lower response to vaccines. Data are scarce on long-term persistence of human serum bactericidal antibody (hSBA) after a meningococcal C conjugate (MCC) vaccine in HIVI youth; the authors aimed to describe this persistence in HIVI. METHODS: HIVI and HIV uninfected individuals (HIVU), aged 2-18 years, CD4 >15% were recruited. Seroprotection (hSBA ≥1:4) at baseline and at 12-18 months after immunization was evaluated and the association of the different factors with the long-term persistence was calculated using logistic regression...

Pericytes regulate key neurovascular functions of the brain. Studies in pericyte-deficient transgenic mice with aberrant signaling between endothelial-derived platelet-derived growth factor BB (PDGF-BB) and platelet-derived growth factor receptor β (PDGFRβ) in pericytes have contributed to better understanding of the role of pericytes in the brain. Here, we studied PdgfrβF7/F7 mice, which carry seven point mutations that disrupt PDGFRβ signaling causing loss of pericytes and vascular smooth muscle cells (VSMCs) in the developing brain...

Background: HIV-induced immunodeficiency has been implicated as a key factor for risk of cancer. Neoplasia is considered to result from accumulation of damage to the genome. Polymorphisms in repair genes, such as the XRCC1 and WRN, have been associated with susceptibility to development of cancer in patients with HIV/AIDS. The aim of this study was to analyze the frequency of polymorphisms in XRCC1 (Arg399Gln) and WRN (Cys1367Arg) in patients with HIV/AIDS with or without cancer. Materials and Methods: Genotyping for analysis of polymorphisms was carried out by PCR (Polymerase Chain Reaction) and RFLP (Restriction Fragment Length Polymorphism)...

Acute hepatitis C virus infection remains a major health concern in human immunodeficiency virus(HIV)-infected men who have sex with men (MSM). New direct-acting antiviral agent (DAA) combination therapy has not yet been approved for the treatment for acute hepatitis C virus(HCV), thereby potentially causing deferral of HCV treatment. Therefore, we aimed to study the course of liver disease after an episode of acute HCV. This study is a retrospective single-centre cohort of HIV-positive MSM with acute HCV infection...

Immunodeficient mice are crucial models to evaluate the efficacy of monoclonal antibodies (mAbs). When studying mAb pharmacokinetics (PK), protection from elimination by binding to the neonatal Fc receptor (FcRn) is known to be a major process influencing the unspecific clearance of endogenous and therapeutic IgG. The concentration of endogenous IgG in immunodeficient mice, however is reduced, and this effect on the FcRn protection mechanism and subsequently on unspecific mAb clearance is unknown, yet of great importance for the interpretation of mAb PK data...

BACKGROUND: The antiretroviral medication, tenofovir disoproxil fumarate (TDF), is used by most human immunodeficiency virus-infected persons in the United States despite higher risks of chronic kidney disease. Although chronic kidney disease is a strong risk factor for heart failure (HF), the association of TDF with incident HF is unclear. METHODS AND RESULTS: We identified 21 435 human immunodeficiency virus-infected patients in the United States Veterans Health Administration actively using antiretrovirals between 2002 and 2011...

Background South Africa has one of the highest rates of rape in the world, but this barely seems to surprise anyone. It is extremely disturbing, especially when children and elderly women are raped. Women and children are usually the weakest group in society physically, as well as the most exposed to abuse and neglect. It should be the responsibility of a civil society to protect these vulnerable groups from harm. Objective This study investigated the trend of rapes among elderly women in the Mthatha area of South Africa...

Recent studies have shown that metal and metal oxide have a potential function in antitumor therapy. Our previous studies demonstrated that cuprous oxide nanoparticles (CONPs) not only selectively induce apoptosis of tumor cells in vitro but also inhibit the growth and metastasis of melanoma by targeting mitochondria with little hepatic and renal toxicities in mice. As a further study, our current research revealed that CONPs induced apoptosis of human melanoma stem cells (CD271(+/high) cells) in A375 and WM266-4 melanoma cell lines and could significantly suppress the expression of MITF, SOX10 and CD271 involved in the stemness maintenance and tumorigenesis of melanoma stem cells...

REVIEW
Lutz G Gürtler, Josef Eberle
Transmission of infectious agents might be associated with iatrogenic actions of charitable help in health care. An example is the vaccination against yellow fever in USA that transmitted hepatitis B virus. Another example is injections of praziquantel for treatment and cure of schistosomiasis in Central and Northern Africa, with a focus in Egypt that has spread hepatitis C virus. There is no indication that human T-lymphotropic virus type 1 was spread by injection treatment for African trypanosomiasis, syphilis and treponematosis, but these treatments might have contributed to the early spread of human immunodeficiency virus type 1 (HIV-1) in Central Africa...

OBJECTIVE: The Human Immunodeficiency Virus (HIV) has an impact on the brain, even when the infection is well-controlled with modern highly-active antiretroviral therapy (HAART). While dementia is rare in those on HAART, milder cognitive impairment is common. The causes, patterns, and evolution of brain dysfunction in people living with HIV remain uncertain. We evaluate whether electrophysiological methods provide informative measures of brain dysfunction in this population. METHODS: A systematic literature search identified studies that used EEG or MEG to evaluate persons living with HIV published between 1996 (when HAART became available) and 2016...

Genome-wide DNA replication timing (RT) profiles reflect the global 3D chromosome architecture of cells. They also provide a comprehensive and unique megabase-scale picture of the cellular epigenetic state. Thus normal differentiation involves reproducible changes in RT and transformation generally perturbs these, although the potential effects of altered RT on the properties of transformed cells remain largely unknown. A major challenge to interrogating these issues in human acute lymphoid leukemia (ALL) is the low proliferative activity of most of the cells, which may be further reduced in cryopreserved samples and difficult to overcome in vitro...
