While HIV-2 is a causative agent for AIDS in addition to the better studied HIV-1, there is currently no suitable animal model for experimental studies for HIV-2 infection and evaluating promising drugs in vivo. Here we evaluated humanized mice for their susceptibility to HIV-2 infection and tested a single-pill three drug formulation of anti-retrovirals (NRTIs abacavir and lamivudine, integrase inhibitor dolutegravir) (trade name, Triumeq(R)). Our results showed that hu-mice are susceptible to HIV-2 infection showing persistent viremia and CD4 T cell loss, key hallmarks of AIDS pathogenesis...

The advent of anti-retroviral therapy (ART) has transformed infection by the type 1 human immunodeficiency virus (HIV) from a rapidly fatal disease to a chronic illness with excellent long-term survival rates. Although HIV primarily targets the adaptive arm of host immunity, it simultaneously impacts the innate immune system and has profound implications for lung health even when viral suppression is achieved with ART. The lung has evolved a unique array of innate immune defenses and the pathophysiological interactions between HIV and the pulmonary innate immune system deserve particular attention...

BACKGROUND: Approximately fifty percent of patients with acute myeloid leukemia can be cured with current therapeutic strategies which include, standard dose chemotherapy for patients at standard risk of relapse as assessed by cytogenetic and molecular analysis, or high-dose chemotherapy with allogeneic hematopoietic stem cell transplant for high-risk patients. Despite allogeneic hematopoietic stem cell transplant about 25% of patients still succumb to disease relapse, therefore, novel strategies are needed to improve the outcome of patients with acute myeloid leukemia...

BACKGROUND: Regimen change is a major challenge for the sustainability of human immunodeficiency virus (HIV) treatment program. In a resource limited setting where treatment options are limited, designing strategies to increase the durability of original regimen are essential. However, information's on rate of initial regimen change and its predictors is scarce in Ethiopia. Therefore, the purpose of this study was to assess the rate of initial highly active anti retroviral therapy (HAART) regimen change and its predictors among adult HIV patients at the University of Gondar Referral Hospital, Northwest Ethiopia...

BACKGROUND: In many countries in Asia, the HIV epidemic is in a concentrated phase, with high prevalence in certain risk groups, such as men who inject drugs. There is also a rapid increase of HIV among women. The latter might be due to high levels of sero-discordant couples and increasing transmission from male to female partners over time. METHODS: All adult married patients initiating antiretroviral treatment at four out-patient clinics in Quang Ninh province in north-eastern Vietnam between 2007 and 2009 were asked to participate in the study...

REVIEW
Dharmendra Kumar, Taruna Anand, Wilfried A Kues
The recent establishment of induced pluripotent stem (iPS) cells promises the development of autologous cell therapies for degenerative diseases, without the ethical concerns associated with human embryonic stem (ES) cells. Initially, iPS cells were generated by retroviral transduction of somatic cells with core reprogramming genes. To avoid potential genotoxic effects associated with retroviral transfection, more recently, alternative non-viral gene transfer approaches were developed. Before a potential clinical application of iPS cell-derived therapies can be planned, it must be ensured that the reprogramming to pluripotency is not associated with genome mutagenesis or epigenetic aberrations...

INTRODUCTION: Despite the advent of modern technologies, India is still grappling with the HIV/AIDS pandemic. Stigma is one of the key aspects which can interfere with HIV test-seeking behaviour, care-seeking behaviour upon diagnosis, quality of care given to HIV-positive patients and perception and treatment of People Living with HIV/AIDS (PLHA) by communities, families, and partners. AIM: To determine the perceived stigma associated with HIV/AIDS and its correlates among PLHAs attending the Anti Retroviral Therapy (ART) centre of North Bengal Medical College, Darjeeling, West Bengal, India...

Bowen's disease (BD) is a form of squamous cell carcinoma in situ often associated with human papillomavirus. Co-infection with human immunodeficiency virus (HIV) is associated with a greater risk of malignancy. We describe a case of BD in a 52-year-old unmarried HIV-positive male who presented with extensive skin lesions of 1-year duration. Histopathology was suggestive of BD. He had been tried with topical imiquimod cream and cryo-therapy for 6 months. We observed no response for these above therapies. He was started on with anti-retroviral therapy (ART) as his CD4 count was 253 cells/mm(3)...

Non-adherence remains a perplexing issue in HIV treatment. After decades of research supporting the efficacy of antiretroviral therapy, non-adherence to medication remains an important issue. For patients who are non-adherent to anti-retroviral therapy (ART), there appears to be a mismatch between their model of illness and the necessity for ART treatment. We propose that 'active visualisation' is a technique that could be utilised to improve understanding of treatment and subsequently adherence for both individuals living with HIV and those at-risk of infection...

BACKGROUND: HIV-associated neurocognitive disorder (HAND) remains highly prevalent despite effective anti-retroviral therapy (ART). A number of adjunctive pharmacotherapies for HAND have been studied with disappointing results, but preliminary data suggest that lithium may provide clinical benefit. In addition, the low cost of lithium would facilitate access in low- and middle-income countries which carry the greatest burden of HIV. METHODS: Our objective was to evaluate the 24-week efficacy and safety of lithium in patients with moderate to severe HAND...

: The envelope (Env) glycoprotein of HIV is the only intact viral protein expressed on the surface of both virions and infected cells. Env is the target of neutralizing antibodies (Abs) and has been the subject of intense study in efforts to produce HIV vaccines. Therapeutic anti-Env Abs can also exert antiviral effects via Fc-mediated effector mechanisms or as cytotoxic immunoconjugates, such as immunotoxins (ITs). In the course of screening monoclonal antibodies (MAbs) for their ability to deliver cytotoxic agents to infected or Env-transfected cells, we noted disparities in their functional activities...

INTRODUCTION: Esophageal cancer (EC) and human immunodeficiency virus (HIV) are common in parts of South Africa. Squamous cell carcinoma of the esophagus in KwaZulu-Natal, South Africa presents generally in advanced stages and is mostly palliated by the deployment of self-expandable metal stent (SEMS). This study analyses these relationships between coexistent HIV infection, SEMS deployment, and survival scores. METHODOLOGY: Information on patients managed with SEMS between October 2013 and December 2014 was retrieved from a prospective database of EC and followed up until April 2015...

INTRODUCTION: National AIDS Control Organization (NACO) has expanded the reach of anti retroviral therapy (ART) to combat the epidemic of HIV/AIDS in India which has one of the largest populations of people living with HIV/AIDS (PLWHA) in the world. One of the major challenges related to ART is a lifelong commitment by patients to adhere diligently to daily medication dosing schedules and scheduled visits to the ART center. Hence, the current study is carried out to assess the drug adherence rate and loss to follow-up (LFU) among PLWHA attending ART centre of a tertiary care hospital in Western India...
