Clinic-based ART Diagnostic Evaluation

Acquired Immunodeficiency SyndromeHIV Infection2 more

The study is funded through the Office of the Global AIDS Coordinator (OGAC #KE-07-0044). The purpose of this study is two-fold. The first purpose is to see if routine monitoring of the level of HIV virus in the blood (viral load) every six months is superior to monitoring by standard clinical evaluations and or immune status (CD4 count) with intermittent viral load monitoring in adults receiving antiretroviral therapy (ART). The second purpose is to understand the cost implications and possible benefits of routine HIV viral load monitoring.

Rapid Initiation of Antiretroviral Therapy to Promote Early HIV/AIDS Treatment in South Africa (RapIT...

HIV

One of the most serious challenges facing antiretroviral therapy (ART) programs for HIV/AIDS in resource-constrained settings is the failure of ART-eligible patients to complete the steps required to initiate treatment. The high rate of loss to care of patients who are treatment-eligible at HIV diagnosis may be due in part to the large number of steps required between receiving an HIV diagnosis and obtaining the first dose of antiretrovirals (ARVs). In South Africa, these steps usually require approximately four clinic visits over a period of 2-8 weeks before a patient can start treatment. One strategy proposed for reducing losses among those eligible for ART is to simplify and condense the steps required for starting treatment. This is now possible because new, point-of-care (POC) tests for CD4 counts and tuberculosis (TB) diagnosis are available. These technologies can be combined with changes to clinic schedules to allow all steps required for ART initiation under South African guidelines (lab tests, physical exam, education) to take place on the day the patient presents for an HIV test. This study is a randomized strategy evaluation of the feasibility, effectiveness, and cost-effectiveness of rapid ART initiation. Outpatient, non-pregnant, HIV-positive adults who come to a South African clinic for an HIV test, consent to study participation, and are eligible for ART will be randomized 1:1 to rapid ART initiation or to standard care. Those who are assigned to rapid ART initiation will have the possibility of receiving their first dose of ARVs as early as the same day, while those who are assigned to standard care will follow the clinic's usual procedures for starting ART. Rapid ART initiation for HIV-positive pregnant women, which has recently become the standard of care in South Africa, will also be assessed in a programmatic evaluation conducted alongside the randomized evaluation, with a retrospective comparison group. The primary study outcome for non-pregnant adults will be remaining alive, in care and virally suppressed 10 months after having a positive HIV test at the study site or making a first HIV-related visit. The primary study outcome for pregnant women will be adherence to ART until delivery. The cost effectiveness of the rapid initiation strategy will be assessed as the cost per patient achieving the primary outcome for each population.

Music for Health Project

Human Immunodeficiency Virus

The overall goal of this project is to use technology to improve adherence to antiretroviral therapy (ART)and increase access to ART adherence care for those HIV+ persons living in rural areas. The LIVE Network audio music program mobile application (app) is innovative, practical, portable, and could be rapidly scaled up to address the adherence self-management needs of rural groups nationwide. If successful, the impact on HIV care will be immense and could transform the delivery of HIV self-management and adherence education by overcoming barriers of geographic isolation, transportation, stigma and confidentiality in this vulnerable group.

Advanced Neuroimaging Evaluation of the Central Nervous System Biological Changes Associated With...

HIV Disease

In this study we will use a multi-modal imaging approach of MRS and fMRI to comprehensively assess the biological changes in the brain associated with EFV-based regimen (EFV/FTC/TDF), specifically alterations in the brain circuitry, function and local neurochemistry, and their correlation with neuropsychological function. In a cohort of HIV-infected patients who are clinically stable on the commonly use regimen of EFV/emtricitabine (FTC)/truvada (TDF) or Atripla, we propose to replace the EFV component with a new integrase inhibitor, elvitegravir (EVG) boosted with cobicistat (COBI), given as the EVG/COBI/FTC/TDF Single Tablet Regimen (STR) to evaluate the EFV-related neural alterations. This is a multidisciplinary study which involves a team of infectious disease experts in the field of HIV, neuroradiologists with expertise in fMRI and MRS techniques to study various central nervous system and psychiatric disorders and a psychiatrist with experience and expertise in research on abnormalities of affective and motivational processing in the context of neuropsychiatric disorders. We will utilize the established clinical research platform in the Infectious Disease outpatient clinical practice at the Brigham and Women's Hospital, where there is currently have many ongoing HIV-related studies and a large panel of HIV-infected patients motivated to be involved in clinically relevant research. We propose to use advanced neuroimaging to measure biologically changes in the brain associated with long-term EFV use with the following specific aims: Determine changes in neurometabolites measured by MRS in the brain associated with long-term EFV use Assess for alterations in neural activity correlated with affective symptoms associated with EFV vs STR use using fMRI, and their associations with changes in neurometabolites assessed by MRS, and with changes in cognition assessed by Trail Making and Digit Substitution Tests. Determine changes in emotion, cognition and sleep quality after switching from EFV to STR, and how they correlate with subject treatment preference. This clinical study will extend our current understanding of EFV neurotoxicity by further defining the nature of these biological changes. Further elucidation of the neurobiological underpinnings of EFV-induced CNS toxicity will have clinical relevance in improving the quality of life and drug adherence of HIV-infected patients on ART, especially among older patients or those with baseline neuropsychiatric disorders, whom at baseline are more vulnerable to neurocognitive decline from long-term HIV infection.

The Use of Peer Referral Incentives to Increase Demand for Voluntary Medical Male Circumcision in...

HIV Infection

The Centre for Infectious Disease Research in Zambia (CIDRZ) and researchers from the University of North Carolina at Chapel Hill (UNC) have partnered to pilot an peer-referral incentive program to increase voluntary medical male circumcision (VMMC) uptake in Zambia. The program allows each man coming for circumcision to refer up to 5 uncircumcised men in their social network for VMMC services and receive a monetary reward for each successful referral. The peer-referral program offers several advantages over traditional demand-creation approaches that rely on employing mobilizers or community health workers (CHWs). The amount of the monetary incentive will be analogous to the amount of incentive that CHWs might receive for comparable effort, making the program suitable for large-scale expansion. The effect of the peer-referral program on uptake of VMMC services will be evaluated using a rigorous methodology proposed by UNC researchers.

Effect of Omega 3 Fatty Acids on Oxidative Stress in HIV Seropositive Patients

HIV/AIDS

Introduction: Highly active antiretroviral therapy (HAART) has showed its effectiveness in the prevention of complications in seropositive for HIV patients. However, they develop some manifestations such as lipodystrophy, dyslipidemia, and glucose intolerance increasing cardiovascular risk. Clinical trials in general population and in patients on hemodialysis have demonstrated a significant reduction in cardiovascular events using fish oil. Omega-3 fatty acids are believed to be beneficial in prevention of atherosclerosis reducing lipids levels specially triglycerides. Also in general populations it has been described a benefit effect of omega 3 acids on oxidative stress. Objective: to know the effect of omega 3 acids on different markers of oxidative stress in seropositive HIV patients. Methods: We will perform a randomized parallel controlled clinical trial in seropositive HIV patients from 20 to 55 years old on clinical score A1, A2, B1 or B2 who received HAART. They will be randomly assigned to receive omega 3 fatty acids 2.4 g (Zonelabs, Marblehead MA) or placebo for 6 months. At baseline anthropometric measurements, lipid profile, glucose and stress oxidative levels (nitric oxide, malondialdehyde, total glutathion, and lipid peroxidation products) will be evaluated. Sample size was calculated according to different variables. We selected the biggest one calculated for a difference in nitric oxide of 25% after treatment between groups and a standard deviation (SD) value of 10µmol/L. Whit this information we obtained a sample size of 31 patients per group for an 80% statistical power with α= 0.05. Assuming a 15% patient lost, a sample size of 35 per group was considered.

Pharmacokinetics Study of GSK1265744 in Subjects With Severe Renal Impairment

InfectionHuman Immunodeficiency Virus1 more

GSK1265744 (744) is an integrase strand transfer inhibitor (INSTI) currently in development for both the treatment and prevention of human immunodeficiency virus (HIV) infection. Renal elimination of unchanged 744 is extremely low, with no parent 744 detected in the urine after a single 30 mg radiolabeled dose. Despite the minimal contribution of renal clearance on overall 744 elimination, renal impairment may potentially inhibit some pathways of hepatic and gut drug metabolism and transport, and as a result may impact 744 pharmacokinetics. The current Food and Drug Administration (FDA) draft guidance for renal impairment studies suggests that a pharmacokinetic (PK) study in patients with renal impairment be conducted even for those drugs primarily metabolized or secreted in bile. The study will be comprised of two cohorts (severe renal impairment and normal renal function) of 8 subjects each. Upon enrolment, each subject will be admitted to the study center and undergo serial PK sampling following a single dose of oral 744 30 milligrams (mg). Subjects will return to the clinic for follow-up evaluations 10-14 days after the 744 30 mg dose.
