INTRODUCTION: The concept of "therapeutic citizenship" has drawn attention to ways in which public testimony, the "story-telling in the public sphere" undertaken by people living with HIV (PLHIV), has shaped the global response to the epidemic. This paper presents qualitative findings from two large studies in eastern Africa that reveal how the advent of population-based HIV testing campaigns and efforts to accelerate antiretroviral "treatment for all" has precipitated a rapidly expanding therapeutic citizenship "project," or social movement...

There is little information available on the possible toxic effects that antiretroviral (ARV) drugs used for the treatment of human immunodeficiency virus (HIV)-infected subjects, may have on the central nervous system (CNS) resident cells. Moreover, it is unclear whether the efficacy of the ARV drugs may also be due to their ability to exert extravirological effects on factors responsible for the development of HIV brain injury, e.g. matrix metalloproteinases (MMPs). This study investigates the toxicity of three different ARV drugs and on their ability to modulate levels and expression of gelatinases A (MMP-2) and B (MMP-9) in astrocytes...

BACKGROUND: Novel antiretroviral formulations that are palatable, safe, and effective are needed for infants and children. METHODS: PRINCE-2 is an ongoing clinical trial assessing safety, efficacy, and palatability of once-daily atazanavir powder formulation boosted with ritonavir (ATV+RTV) plus optimized dual NRTI therapy in ARV-naïve/experienced children with screening HIV-1 RNA ≥1000 copies/mL. Children aged 3 months to <11 years received ATV+RTV by 5 baseline weight bands: 5 to <10kg=150/80mg; 5 to <10kg=200/80mg; 10 to <15kg=200/80mg; 15 to <25kg=250/80mg; and 25 to <35kg=300/100mg...

Heterotropic interactions between atorvastatin (ARVS) and dronedarone (DND) have been deciphered using global analysis of the results of binding and turnover experiments for pure drugs and their mixtures. The in vivo presence of atorvastatin lactone (ARVL) was explicitly taken into account by using pure ARVL in analogous experiments. Both ARVL and ARVS inhibit DND binding and metabolism, while significantly higher affinity of CYP3A4 towards ARVL makes the latter the main effector in this system. Molecular dynamics simulations reveal significantly different modes of interactions of DND and ARVL with the substrate binding pocket and with the peripheral allosteric site...

(no author information available yet)
Progressive multifocal leukoencephalopathy (PML) is a severe demyelinating disease that affects the central nervous system, which has high morbidity and mortality and no effective, targeted therapies are available. According to the data from developing countries, it affects about 3 to 5% patients who are HIV positive. We present a case of a 27-year-old patient, who got infected with the HIV virus from his mother. The patient had poor compliance to the therapy since its initiation. Due to poor compliance and immunological and virological failure of the first line ARVs, the patient developed PML...

INTRODUCTION: The use of cardiopulmonary bypass (CPB) leads to increased fluid filtration and edema. The use of artificial colloids to counteract fluid extravasation during cardiac surgery is controversial. Beneficial effects on global fluid loading, leading to better cardiac performance and hemodynamics, have been claimed. However, renal function and coagulation may be adversely affected, with unfavorable impact on outcome following cardiac surgery. METHODS: Forty patients were randomly allocated to study groups receiving either acetated Ringer's solution (CT group) or hydroxyethyl starch (HES group, Tetraspan®) as CPB priming solution...

BACKGROUND: Typical symptoms of an acute human immunodeficiency virus (HIV) infections like fever and rash are not specific and can be caused by a multitude of other pathogens, such as Zika or rickettsiosis. Up to 30% of primary HIV infection do not present with the typical flu-like symptoms and thus represent a diagnostic challenge. In this report, we describe a rare case of optic neuropathy as the initial presentation of primary HIV infection, which resulted in irreversible blindness...

Globally 1.8 million children are living with human immunodeficiency virus (HIV), yet only 51% of those eligible actually start treatment. Research and development (R&D) for pediatric antiretrovirals (ARVs) is a lengthy process and lags considerably behind drug development in adults. Providing safe, effective, and well-tolerated drugs for children remains critical to ensuring scale-up globally. We review current approaches to R&D for pediatric ARVs and suggest innovations to enable simplified, faster, and more comprehensive strategies to develop optimal formulations...

Introduction: Home Based Testing and Counselling (HBTC) aims at reaching individuals who have low HIV risk perception and experience barriers which prevent them from seeking HIV testing and counseling (HTC) services. Saturating the community with HTC is needed to achieve the ambitious 90-90-90 targets of knowledge of HIV status, ARV treatment and viral suppression. This paper describes the use of health belief model and community participation principles in HBTC to achieve increased household coverage and HTC uptake...

BACKGROUND: Before Pre-Exposure Prophylaxis (PrEP) was officially recommended and made available, a few surveys among gay and bisexual men, and persons living with HIV/AIDS (PLWHA), identified an informal use of antiretrovirals (ARVs) for PrEP among HIV-negative individuals. Before PrEP availability in Italy, we aimed to assess whether PLWHA in Italy shared their ARVs with HIV-negative individuals, whether they knew people who were on PrEP, and describe the level of awareness and discussion on this preventive measure among them and people in their close circle...

BACKGROUND: Avian reovirus (ARV) is an important poultry pathogen that can cause immunosuppression. In this study, RNA-Seq technology was applied to investigate the transcriptome-wide changes of DF-1 cells upon ARV infection at the middle stage. RESULTS: Total RNA of ARV-infected or mock-infected samples at 10 and 18 h post infection (hpi) was extracted to build RNA-Seq datasets. Analysis of the sequencing data revealed that the expressions of numerous genes were altered, and a panel of differentially expressed genes were confirmed with RT-qPCR...

Laboratory data and prior pediatric reports indicate that HIV protease inhibitor (PI)-based antiretroviral therapy (ARV) kills gametocytes and reduces rates of gametocytemia, but not asymptomatic parasitemia, in a high malaria-transmission area. To determine whether ARV regimen impacts these rates in areas with less-intense malaria transmission, we compared asymptomatic parasitemia and gametocytemia rates in HIV-infected children by ARV regimen in Lilongwe, Malawi, an area of low-to-moderate transmission intensity...

Human immunodeficiency virus type-1 (HIV-1) infection leads to acquired immunodeficiency syndrome (AIDS), a severe fatal viral infection that has claimed approximately 658,507 lives in the US within the year 2010-2014. Antiretroviral (ARV) therapy has proven to inhibit HIV-1, but unlike other viral illness, not cure the infection. Among various Food and Drug Administration (FDA)-approved ARVs, nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) are most effective in limiting HIV-1 infection. This review focuses on NRTIs mechanism of action and metabolism...

INTRODUCTION: Metabolic disorders in people living with HIV/AIDS (PLH) have been described even before the introduction of antiretroviral (ARV) drugs in the treatment of HIV infection and are risk factors for cardiovascular diseases. Based on this, the purpose of this study was to assess metabolic disorders and cardiovascular risk in PLH before the initiation of antiretroviral treatment (ART). METHODS: This was a cross-sectional descriptive study of 87 PLH without the use of ART, which was carried out between January and September 2012 at a specialized infectious diseases center in Minas Gerais, Brazil...

BACKGROUND: Perinatally HIV-infected (PHIV) children are at risk for undervaccination and poor vaccine response at four years of age. Childhood vaccine coverage and immune response were compared between PHIV and HIV-exposed uninfected (HEU) children in Latin America and the Caribbean. METHODS: PHIV and HEU children were enrolled prospectively at fifteen sites from 2002-2009. Full vaccination by age four years was defined as: three hepatitis B virus (HBV) vaccine doses; four tetanus toxoid-containing vaccine doses; three doses of Haemophilus influenzae type b (Hib) vaccine by age 12 months or ≥1 dose given after age 12 months; one measles-containing vaccine dose; one rubella-containing vaccine dose...

BACKGROUND: Efavirenz is currently suggested as an alternative to recommended antiretroviral (ARV) regimens by the Department of Health and Human Services for the treatment of HIV-1 in ARV-naive patients. A mid-dosing interval therapeutic range between 1000 and 4000 ng/mL for efavirenz has been proposed in the literature, with patients more likely to experience virologic failure below this range and adverse effects above. The current study reports an analysis of virologic outcome between those above, below, or within the reported efavirenz therapeutic range (1000-4000 ng/mL) and within subgroups...
