Filter by:This study seeks to develop, implement, and assess an innovative 15-session couple-based intervention to be delivered in a group format to young parents that aims to strengthen relationships and reduce HIV risk. The ultimate goal of our intervention is to reduce HIV/STD risk (concurrency, number of partners, unprotected sex), strengthen relationships, and improve parenting among young parenting heterosexual couples.
HIV continues to spread among Black men who have sex with men (MSM), but few interventions target high-risk Black men who have sex with men and women (MSMW). Black MSMW with histories of childhood sexual abuse (CSA) may be an especially vulnerable population for: a) high-risk sexual behaviors; b) negative psychological sequelae (e.g., depressive or posttraumatic stress disorder (PTSD) symptoms); and c) neurobiological abnormalities in cardiovascular, neuroendocrine and/or immune systems (e.g., cortisol and norepinephrine), and HIV/AIDS progression. The purpose of this study was to test an HIV risk reduction intervention, guided by the Social Learning Theory, the Ecological Model, and the concept of allostatic load, a composite of the cumulative effects of stress on biological systems including psychoneuroimmunologic markers. The investigators tested the 6-session Enhanced Sexual Health Intervention for Men (ES-HIM) on 88 non-gay identifying HIV-positive Black MSMW with histories of CSA. The outcomes were to reduce high-risk sexual behaviors (i.e., unprotected anal and vaginal sex and number of sex partners) and negative psychological symptoms of depression and PTSD. Links between these outcomes and biomarkers of stress were also explored. Randomization to either the ES-HIM or a health promotion control group occurred with study participants assessed at baseline, post, 3- and 6-months.
The overall aim of the BREATHER trial is to evaluate the role of Short-Cycle Therapy (SCT) in the management of HIV-infected young people who have responded well to antiretroviral therapy (ART) and to determine whether young people with chronic HIV infection undergoing Short-Cycle Therapy of five days on ART and two days off maintain the same level of viral load suppression as those on continuous therapy, over 48 weeks. To assess the advantages and disadvantages of the strategy, the incidence of toxicities, immunological control, resistance mutations, acceptability, quality of life and adherence to the randomised strategy will also be compared. Importantly, because of insufficient data on short-term viral load rebound after stopping ART in this population, the trial will incorporate an initial pilot phase in selected centres, to assess the safety of the SCT strategy by evaluating detailed HIV-1 RNA profiles of participants on the SCT strategy.
Early childhood (up to age 5 yrs) is a period of dramatic change in the cognitive, emotional, social, and behavioral domains; children continuously progress by observing and interacting with the world around them. In the face of economic instability and nutritional, medical and educational deprivation, HIV-affected very young children are the most vulnerable HIV subgroup globally because their families are often the most vulnerable, with little margin for sustaining a favorable developmental milieu for the child. Through strategic caregiver interventions during this sensitive period of child neurodevelopment, our study findings have the potential for positively re-directing the developmental trajectories of tens of millions of HIV-affected children globally.
The aims of this project are to: 1. To evaluate the pharmacokinetics of first line antituberculosis drugs (isoniazid, rifampicin, pyrazinamide and ethambutol) when applying the 2010 WHO/IUATLD dosing guidelines across pediatric populations (0-12 years of age, HIV infected and uninfected, and with varied nutritional status) in Cape Town, South Africa and Blantyre, Malawi. 2. To evaluate an 8-hourly weight band-based dosing strategy for lopinavir/ritonavir using the commercially available lopinavir/ritonavir (4:1 ratio) in children in South Africa receiving rifampicin-based antituberculosis treatment. 3. To evaluate the pharmacokinetics of nevirapine in children in Malawi receiving rifampicin-based antituberculosis treatment.
Chronic kidney disease (CKD) is an emerging problem in patients with treated HIV. Antiretroviral therapy associated renal dysfunction has been predominantly described in terms of reduced glomerular filtration (eGFR). Proteinuria is a key component of CKD and may occur in the absence of significant reductions in eGFR. This substudy is an exploration of changes in urinary protein excretion in a randomised, open-label study to evaluate the efficacy and safety of MVC as a switch for either nucleoside or nucleotide analogue reverse transcriptase inhibitors (N(t)RTI) or boosted protease inhibitors (PI/r) in HIV-1 infected individuals with stable, well-controlled plasma HIV-RNA while taking their first N(t)RTI + PI/r regimen of combination antiretroviral therapy (cART).
The proposed project will test an HIV prevention intervention for Latino parent-adolescents dyads. This randomized controlled trial will: 1. Recruit and randomize 320 parent-adolescent dyads into a Latino family-based HIV prevention intervention or a family-based General Health Promotion condition. 2. Determine the efficacy of the Latino Family-based HIV prevention intervention from assessment of changes in HIV-related sexual behavior and attitudes over 18 months among a sample of 320 Latino parent-adolescent dyads. 3. Determine the efficacy of the Latino Family-based HIV prevention intervention from assessment of changes in family relationships and parental monitoring/supervision over 18 months among a sample of 320 Latino parent-adolescent dyads. 4. Examine the association of other important constructs, such as religiosity, acculturation, cultural values, and sexual socialization with the primary outcomes. Based on a thorough review of the literature and preliminary data from a recent, small pilot study, the investigators hypotheses are: 1. Compared to the General Health Promotion Control condition, the Family-Based HIV Prevention intervention will result in greater change with regard to primary outcome measures of safer sexual behavior (recent sexual activity, the number of unprotected sex acts, and intentions to use condoms) and safer HIV-related attitudes. 2. Compared to the General Health Promotion Control condition, the Family-Based HIV Prevention intervention will result in greater change with regard to family relationships and parental monitoring/supervision through improved parent-child communication skills and they will mediate the intervention impact. 3. Religiosity, acculturation, cultural values, and sexual socialization will have meaningful associations with the primary outcomes and will act as moderators of intervention impact.
The objective of this randomized, controlled trial is to determine if adding a protein-calorie supplement (PCS) to the standard treatments for tuberculosis (TB) and HIV will improve health outcomes. The investigators will enroll 180 HIV-positive women with newly diagnosed active TB and without prior anti-retroviral therapy (ART). At baseline, the investigators will conduct dietary interviews, measure body composition, randomize subjects to receive a PCS (plus micronutritional supplements [MNS]) or control (MNS only) for the 6-month duration of anti-TB therapy (ATT) plus an additional 2 mos (8 mos total). Subjects will be followed monthly and have CD4 counts at baseline, 2, 8 and 12 months. At 2 months (i.e., at the end of the 4 drug intensive phase of TB treatment and start of the 2 drug continuation phase), all subjects will be started on anti-retroviral therapy (ART) based on Tanzanian Ministry of Health guidelines (currently: AZT/3TC/efavirenz). The primary endpoint will be change in CD4 count after 8 months (i.e., at end of PCS/MNS intervention and 2 months after completion of ATT).
The purpose of this study is to determine whether the use of a Computerized Decision Support System (CDSS) in form of alerts to clinicians enhances early detection of immunological treatment failure in HIV patients.
This study tests the effectiveness of the bilingual Health and Success program, which aims to support Latino parents and schools in their efforts to promote the academic success and healthy choices of youth, with the goal of reducing barriers that lead to elevated levels of HIV/AIDS in urban Latino communities.
