Filter by:The purpose of this study is to provide evidence on the performance and operational characteristics of commercially available dual HIV/syphilis Rapid Diagnostic Tests (RDTs) in Zambia for their introduction into antenatal care and other settings.
Longitudinal cohort study of older-aged people living with HIV infection in southwestern Uganda and age and gender-matched HIV uninfected controls with the primary aim of measuring the epidemiology of cardiovascular and pulmonary disease in this study setting, and particularly the contribution of HIV infection to it.
Combination antiretroviral treatment (cART) effectively suppresses virus replication and partially restores immune functions. However, cART cannot cure HIV infection. This study aim to investigate whether the antiviral immune response can be enhanced and/or viral transcription reactivated with MGN1703. MGN1703 is an agonist to toll-like receptor (TLR) 9. Activation of TLR9 has been shown to augment innate and adaptive immune effector functions, most notably enhanced NK cell and T cell functions. Furthermore, TLR9 agonists have been shown in vitro to reactivate viral transcription in latently infected cells, potentially leading to enhanced recognition of infected cells by the immune effector cells.
Dyslipidemia as a risk factor for cardiovascular disease (CVD) is an increasing problem in HIV-infected patients who are on antiretroviral therapy especially protease inhibitors including atazanavir. Pitavastatin is a new HMG-CoA reductase inhibitor with lesser drug-drug interactions and demonstrable efficacy in decreasing lipid levels in non HIV-infected individuals. The study was conducted as a randomized, double-blind, crossover study comparing the safety and efficacy of pitavastatin versus placebo in HIV-infected patients with dyslipidemia and receiving atazanavir/ritonavir. Patients were randomized to receive either placebo or pitavastatin for 12 weeks, underwent a 2-week washout period, and then were given the other treatment for an additional 12 weeks. Patients were observed for lipid profiles including total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high density lipoprotein (HDL); and the side effects including clinical and laboratory (serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and creatinine phosphokinase (CPK)). The follow-up visits were every 4 weeks until the end of the study.
The iLink Study examines whether a Conditional Economic Incentive (CEI) may be an effective tool for improving linkage to HIV treatment and care following referral for antiretroviral therapy (ART) services from a mobile health clinic in Cape Town, South Africa. The study examines the feasibility and acceptability of using a R300 (approximately $25 as of April 2015) voucher - that is exchanged for cash upon initiation of ART within 3 months - to increase the uptake of ART among men and women living in low-income areas. This pilot study (n=64) includes a randomised control trial, follow-up telephone calls and medical record reviews, and in-depth interviews.
Opioid Substitution Treatment (OST) provides a critical opportunity for HIV testing and linkage to antiretroviral treatment. The EHOST study will evaluate a prescriber-focused intervention to increase HIV testing rates, and optimize antiretroviral treatment, re-engagement and retention outcomes among individuals engaged in OST. 46 OST sites in British Columbia will be randomly allocated into three clusters. Clusters will initiative the intervention at different time points, or steps, with every cluster receiving the intervention.
Kinshasa, Democratic Republic of Congo (DRC), is where human immunodeficiency virus type 1 (HIV-1) appears to have most diversified. The factors that lead to jumpstarting the HIV-1 epidemic remain unclear; mounting evidence suggests medical interventions may have contributed. Hepatitis C virus (HCV) and human T-cell lymphotropic virus type 1 (HTLV-1) are viruses compatible with long-term survival but with broadly similar modes of transmission as HIV. The main objective was to assess the association of past intravenous treatment with HCV and HTLV-1 seropositivity. The investigators hypothesized that medical interventions in the mid-20th century may have facilitated the emergence of HIV-1 in central Africa. To assess the association of injectable treatments with HCV and HTLV-1 infection and to reconstruct past virus dynamics, the investigators conducted a cross-sectional study of 839 elderly long-term inhabitants of Kinshasa, with serological assays followed by amplification and sequencing. Risk factors were assessed through logistic regression. Phylogenetic methods were used to reconstruct the epidemic history of HCV.
This study pilot tests and intervention to help individuals reduce their risk for acquiring or transmitting HIV. The intervention is implemented when people are tested for HIV in an outpatient clinic in rural Uganda. Approximately half of participants will receive the intervention and the other half will receive the usual counseling provided during HIV counseling and testing.
This is an observational study involving retrospective and prospective medical record review covering a total maximum of 104 weeks (24 months) per subject. An Audio Computer- Assisted Self-Interview (ACASI) at study entry will assess demographic and psychosocial variables of study subjects. Data will also be collected to assess clinic level variables. Definitions of engagement, prescription of antiretroviral therapy (ART), and viral suppression in the Continuum of Care (CoC) will utilize common definitions including those by U.S. Department of Health and Human Services (DHHS) and Health Resources and Services Administration (HRSA) HIV/AIDS Bureau (HAB). Data will be collected in a large, simple trial design manner to provide all elements for both the primary and secondary outcomes.
PRO 140 2102 is a multicenter, randomized, double-blind, placebo-controlled, clinical trial of observed systemic, long-acting, anti-HIV treatment with a monoclonal CCR5 antibody (PRO 140) as an adjunct to a new, optimized, oral antiretroviral regimen in HIV-infected injection drug users with viral rebound and documented poor adherence to the previous antiretroviral regimen. Eligible subjects (approximately 76) will be randomized 1:1 to receive an optimized background antiretroviral regimen (OBR) plus supervised weekly subcutaneous treatment with either PRO 140 or placebo. Blood samples for safety and efficacy variables will be obtained over the 24 week duration of the study. Safety will be monitored throughout the course of the study.
