Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiologic agent of Kaposi's sarcoma (KS). It is endemic in a number of sub-Saharan African countries with infection rate of >50%. The high prevalence of HIV-1 coupled with late presentation of advanced cancer staging make KS the leading cancer in the region with poor prognosis and high mortality. Disease markers and cellular functions associated with KS tumorigenesis remain ill-defined. Several studies have attempted to investigate changes of the gene profile with in vitro infection of monoculture models, which are not likely to reflect the cellular complexity of the in vivo lesion environment...

BACKGROUND: Cataracts occur earlier among HIV-infected adults and this is attributed to various intraocular inflammatory processes that result in early degeneration. In this study we purposed to investigate whether HIV infected individuals with cataracts develop heightened intraocular inflammatory processes compared to their HIV negative counterparts by determining the concentration of 8 cytokines in the aqueous humour of HIV-positive adults with cataracts and their HIV-negative counterparts...

BACKGROUND: The benefits of combination anti-retroviral therapy (cART) in HIV-positive pregnant women (improved maternal health and prevention of mother to child transmission [pMTCT]) currently outweigh the adverse effects due to cART. As the variety of cART increases, however, the question arises as to which type of cART is safest for pregnant women and women of childbearing age. We studied the effect of timing and exposure to different classes of cART on adverse birth outcomes in a large HIV cohort in the Netherlands...

HIV-1 nucleocapsid (NCp7) is a two Cys2HisCys zinc knuckle (N-Zn and C-Zn) protein that plays a key role in viral replication. Here we characterize NCp7 conformational dynamics by NMR relaxation dispersion and chemical exchange saturation transfer measurements. While the N-Zn knuckle is conformationally stable, the C-Zn knuckle interconverts on the millisecond time scale between the major state, in which the zinc is coordinated by three cysteines and a histidine, and two folded minor species (with populations around 1%) in which one of the coordination bonds (Cys413-S---Zn or His421-N2---Zn) is hydrolysed...

More than 35 years have elapsed since the initial outbreak of the HIV/AIDS epidemic and the status of a considerable number of patients has changed from a fatal disorder to a chronic one where comorbidities including sarcoidosis and autoimmune diseases have become relevant and dominant. HIV targets the immune system leading to a state of immunodeficiency in a setting of immune activation in which CD4+ T cell depletion plays a critical role. The onset, natural history and course of HIV-associated autoimmune disease has dramatically changed according to the stage of HIV infection and since the introduction of combined anti-retroviral therapy...

Background: Since the time of NACO Antiretroviral (ART) roll-out, generic ART has been the mainstay of therapy. There are many studies documenting the efficacy of generic ART but with the passage of time, failure of therapy is on the rise. As institution of second line ART has significant financial implications both for a program and for an individual it is imperative that we determine factors which contribute towards treatment failure in a cohort of patients on generic antiretroviral therapy...

A wide range of rheumatic and peripheral nervous system disorders may develop in patients with HIV infection, leading to pain, sensory symptoms, and muscle weakness. Over the past three decades, the progress in management of HIV disease with anti-retroviral therapy (ART) has resulted in increased life expectancy for people living with HIV disease. With this new chronicity of the disease has a constellation of chronic musculoskeletal, orthopaedic and rheumatic manifestations has emerged, as potential complications of the disease itself and/or the results of ART treatment regimen and/or because of expected age-related symptoms/manifestations...

BACKGROUND: The landscape of Human Immunodeficiency Virus (HIV) epidemic control is shifting with the United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 benchmarks for epidemic control. Community-based Antiretroviral Therapy (CART) models have improved treatment uptake and demonstrated good clinical outcomes. We assessed the feasibility of integrating community pharmacy as a task shift structure for differentiated community ART in Abuja-Nigeria. METHODS: Stable patients on first line ART regimens from public health facilities were referred to community pharmacies in different locations within the Federal Capital Territory, Abuja for prescription refills and treatment maintenance...

Binge drinking affects the onset and progression of human immunodeficiency virus (HIV)-associated neurological disorders. The HIV-1 transgenic (HIV-1Tg) rat was created with a gag- and pol-deleted HIV-1 viral genome to mimic HIV-infected patients receiving combination anti-retroviral therapy (cART). Docosahexaenoic acid (DHA) is a marine compound that modulates inflammatory responses. Using HIV-1Tg rats subjected to binge exposure to ethanol (EtOH), this study examined whether DHA could reduce the detrimental neurological effects of EtOH and HIV proteins...

OBJECTIVE: HIV-associated sensory neuropathy (HIV-SN) remains common in HIV+ individuals receiving anti-retroviral therapy (ART), even though neurotoxic anti-retroviral drugs (e.g. stavudine) have been phased out of use. Accumulating evidence indicates that the neuropathy is immune-mediated. We hypothesise that chemokines produced locally in the skin promote migration of macrophages and T-cells into the tissue, damaging cutaneous nerves causing HIV-SN. DESIGN: We assessed chemokine receptor expression on infiltrating CD14 and CD3 cells around cutaneous nerves in standardised skin biopsies from HIV-SN+ patients (n = 5), HIV-SN- patients (n = 9) and healthy controls (n = 4)...

BACKGROUND: In spite of the global decline in HIV infections, sub-Saharan Africa still accounts for a non-proportional majority of global new infections. While many studies have documented the importance of facilitating access to anti-retroviral therapy (ART) as a means of reducing infections, the relationship between interpersonal, community, healthcare facility, and policy-level factors and treatment adherence in Africa have not been well-described. The authors examined these factors in the context of prevention of mother-to-child transmission (PMTCT) of HIV in rural north-central Nigeria, where HIV burden is high and service coverage is low...

BACKGROUND: According to World Health Organization (WHO) guidelines, which have also been adopted by the National AIDS Control Organization (NACO), India, Efavirenz-based Anti-Retroviral Therapy (ART) is better in Human-Immunodeficiency-Virus (HIV)-infected patients who are also being treated with Rifampicin-based Anti-Tuberculous Therapy (ATT). However, Efavirenz is much more expensive. We hypothesize that Nevirapine is a cheaper alternative that possesses equal efficacy as Efavirenz in HIV-Tuberculosis (TB) co-infected patients...

OBJECTIVES: To determine the prevalence of chronic ear disease in HIV+, highly active anti-retroviral therapy (HAART)-treated children and compare this to the prevalence in healthy children of similar age living in a similar setting. INTRODUCTION: From previous clinical work in Ethiopia, we suspected that chronic middle ear disease was common both in the general pediatric population and especially among children with HIV/AIDS. Few studies have examined the prevalence of chronic ear disease in HIV + children, particularly in those treated with HAART...

METHODS: We aimed to determine if the adverse event (AE) rate was non-inferior to an AE rate of 2%, a rate considered the global standard of MC safety. Study procedures, AE definitions, and study staff were unchanged from previous PrePex Zimbabwe trials. After PrePex placement and removal, weekly visits assessed wound healing. Men returned on Day 90. Safety was defined as occurrence of moderate and serious clinical AEs. Efficacy was defined as ability to reach the endpoint of complete circumcision...

Women of reproductive age account for nearly half of all HIV-infected people worldwide. Childbearing intention among HIV-infected women is complicated by social and reproductive concerns related to their HIV status. We conducted a cross-sectional study of HIV-infected and HIV-uninfected sexually active South African women aged 17 to 21 in order to compare their childbearing intentions and to identify predictors of the desire to have children among women with HIV. We found the rate of childbearing intention to be similarly high among both HIV-infected and HIV-uninfected study participants (80 and 79% respectively, p=0...

REVIEW
Eman Teer, M Faadiel Essop
The successful rollout of anti-retroviral therapy ensured that HIV is increasingly managed as a chronic condition. HIV-positive persons are therefore exhibiting increased cardiovascular complications. This review focuses on the emerging role of "immunometabolism" within the context of HIV-related immune dysregulation and cardiovascular disease onset. Here, persistent immune activation contributes to pathophysiological perturbations during early infection, resulting in immune cell metabolic reprogramming and the activation of coagulation pathways in HIV-positive individuals...

BACKGROUND: The incidence of tuberculosis (TB) is high among human immunodeficiency virus (HIV) infected Ugandans. Recent evidence suggests that Chronic Pulmonary Aspergillosis and Aspergillus sensitisation might be responsible for significant mortality in patients treated for tuberculosis in Uganda. METHODS: We retrieved and tested paired serum aliquots for 101 HIV-TB co-infected patients at the beginning and week 24 of TB treatment. We tested samples for Aspergillus-specific immunoglobulin G (IgG) and immunoglobulin E (IgE) using ImmunoCAP®; and Aspergillus-specific IgG and total serum IgE using Immulite® immunoassays...

Autonomic dysfunction appears to be prevalent in people living with HIV/AIDS (PLWHA). However, there are limited data on the resting autonomic responses to exercise in active and insufficiently active PLWHA. We aimed to determine whether active PLWHA have better autonomic responses compared with insufficiently active PLWHA. Active PLWHA receiving anti-retroviral therapy (n=13) and insufficiently active PLWHA (n=10) were recruited. A 10-min recording of the supine electrocardiogram was taken. Resting heart rate variability was analyzed from this electrocardiogram...
