BACKGROUND: Since 2006, the Peruvian National TB program (NTP) recommends voluntary counseling and testing (VCT) for all tuberculosis (TB) patients. Responding to the differential burden of both diseases in Peru, TB is managed in peripheral health facilities while HIV is managed in referral centers. This study aims to determine the coverage of HIV screening among TB patients and the characteristics of persons not screened. METHODS: From March 2010 to December 2011 we enrolled new smear-positive pulmonary TB adults in 34 health facilities in a district in Lima...

OBJECTIVE: To identify clinical, sociodemographic and treatment-related factors associated with early virological response in HIV-infected adults starting antiretroviral treatment (ART) in Brazil in 2014-2015. METHODS: Data from four information systems from the Brazilian AIDS Program were combined to create a historical cohort. Unconditional logistic regression models were used to assess the likelihood of not achieving virological suppression (VLS), defined as having either a viral load count (VL) >200 copies/mL or an aids-related death recorded within 180±90 days after treatment initiation...

Treatment options for patients with HIV-1 infection have grown over the past two decades to include multiple fixed-dose combination pharmacotherapies that have greatly simplified administration of antiretroviral therapy (ART) for both patients and providers. Effective virologic control can often be achieved with once-daily use of a single-tablet regimen. Over the past three years, ART drug development has focused on the next generation of fixed-dose combinations for initial and maintenance therapy with improved efficacy, safety and tolerability...

Background HIV-HCV coinfection produces high morbi-mortality. Direct-acting antivirals (DAAs) have shown high efficacy, although special attention should be paid to the risk of drug interactions. However, due to the lack of representativeness of coinfected patients in clinical trials, it is important to know real-world results. Objective To evaluate DAA treatment effectiveness in coinfected patients. We also analyse safety profile of DAA treatment and drug interactions between HCV and HIV therapy. Setting Descriptive study carried in a tertiary hospital of Spain Method HIV-HCV coinfected patients treated with DAAs between November 2014 and June 2016 were included...

Human immunodeficiency virus (HIV) induces a persistent and incurable infection. However, the combined antiretroviral treatment (cART) has markedly changed the evolution of the infection and transformed a deadly disease into a manageable chronic infection. Withdrawal of cART generally leads though to resumption of the viral replication. The eradication of the virus from its cellular and anatomical reservoirs remains a goal-to-achieve for a cure. In this context, developing novel therapies contributing to this aim are an important field of research...

HIV has been reported to be cytotoxic in vitro and in lymph node infection models. Using a computational approach, we found that partial inhibition of transmissions of multiple virions per cell could lead to increased numbers of live infected cells. If the number of viral DNA copies remains above one after inhibition, then eliminating the surplus viral copies reduces cell death. Using a cell line, we observed increased numbers of live infected cells when infection was partially inhibited with the antiretroviral efavirenz or neutralizing antibody...

PURPOSE OF REVIEW: With prolonged life expectancy in HIV-positive patients on combination antiretroviral therapy, the quest for reducing lifelong drug exposure and minimizing or avoiding the toxicities of combination antiretroviral therapy while maintaining viral suppression has emerged when coformulations of antiretroviral agents with improved convenience, and better tolerability and efficacy became available. This review aims to update the current experience with the novel two-drug combination of dolutegravir (DTG) and rilpivirine (RPV) and elucidate the possible applications and limitations of coformulated DTG-RPV in the future...

AIM: While the  therapeutic potential for current long-acting (LA) antiretroviral therapy (ART) is undeniable, ligand-decorated nanoformulated LA-ART could optimize drug delivery to viral reservoirs. The development of decorated ART hinges, however, on formulation processes and manufacture efficiencies. To this end, we compared manufacture and purification techniques for ligand-decorated antiretroviral drug nanocrystals. MATERIALS & METHODS: Ligand-decorated nanoparticle manufacturing was tested using folic acid (FA) nanoformulated cabotegravir...

The determination of the concentrations of antiretroviral drugs in hair is believed to be an important means for the assessment of the long-term adherence to highly active antiretroviral therapy. At present, the combination of tenofovir, lamivudine and nevirapine is widely used in China. However, there was no research reporting simultaneous determination of the three drugs in hair. The present study aimed to develop a sensitive method for simultaneous determination of the three drugs in 2-mg and 10-mg natural hair (Method 1 and Method 2)...

Daily oral antiretroviral therapy (ART) regimens produce limited drug exposure in tissues where residual HIV persists, and suffer from poor patient adherence and disparate drug kinetics, which all negatively impact outcomes. To address this, we developed a tissue- and cell-targeted long-acting 4-in-1 nanosuspension composed of lopinavir (LPV), ritonavir (RTV), tenofovir (TFV), lamivudine (3TC). In four macaques dosed subcutaneously, drug levels over 5 weeks in plasma, lymph node, and peripheral blood mononuclear cells (LNMCs, PBMCs) were analyzed by LC-MS/MS...

Since the era of combined antiretroviral therapy, life expectancy of people living with HIV has been improved and is associated with a change in causes of death. Cancer, both AIDS-defining or non-AIDS-defining cancers, has become the leading cause of death in people living with HIV associated with an increase in the incidence of some cancers compared to the general population. Epidemiology and the identification of risk factors is a crucial issue, particularly to determine the most appropriate prevention and screening strategies in this population...

BACKGROUND: Pre-exposure prophylaxis (PrEP) with antiretrovirals is an efficacious and effective intervention to decrease the risk of HIV (human immunodeficiency virus) acquisition. Yet drug and delivery costs prohibit access in many jurisdictions. In the absence of guidelines for the synthesis of economic evaluations, we developed a protocol for a systematic review of economic evaluation studies for PrEP by drawing on best practices in systematic reviews and the conduct and reporting of economic evaluations...

Persons with HIV who have entered care but have viral load > 1500 copies/mL may be the source of the majority of new HIV infections in the United States. We followed patients engaged in continuity care in the Johns Hopkins HIV Clinical Cohort between January 2010 and August 2015. We estimated person-time spent with viral load > 1500 copies/mL while in care after antiretroviral therapy (ART) initiation, while in care, and while alive. Person-time was classified according to the most recent viral load measurement...

BACKGROUND: NSC260594, a quinolinium derivative from the NCI diversity set II compound library, was previously identified in a target-based assay as an inhibitor of the interaction between the HIV-1 (ψ) stem-loop 3 (SL3) RNA and Gag. This compound was shown to exhibit potent antiviral activity. Here, the effects of this compound on individual stages of the viral lifecycle were examined by qRT-PCR, ELISA and Western blot, to see if its actions were specific to the viral packaging stage...
