Filter by:Alcohol use is increasingly recognized as a key factor in morbidity and mortality among HIV-positive individuals and represents an important public health concern, given its associations with medication non-adherence, increases in viral load, poor immunologic outcomes (lower cluster of differentiation 4, or CD4, counts), drug resistance, lower health care utilization, comorbidities (HIV/viral hepatitis coinfection), and poor health outcomes overall. Adherence to HIV medications has a double public health benefit, both in terms of slowing disease progression and improving health outcomes among HIV-positive individuals and in helping to curb the sexual transmission of HIV. The objective of this study is to implement a multisite comparative effectiveness trial in real-world clinical settings with three intensities of treatment to test the clinical and cost effectiveness of an efficacious, theory-based behavioral intervention (PLUS) in improving adherence to antiretroviral therapy (ART) and alcohol-related outcomes among HIV-positive individuals who drink alcohol at harmful or hazardous levels. The study is being conducted in collaboration between the Center for HIV Educational Studies and Training (CHEST) at Hunter College at the City University of New York (CUNY) and the Spencer Cox Center for Health at the Institute for Advanced Medicine, Mount Sinai Health System.
This randomized controlled trial will explore whether the provision of oral HIV self-test kits to women can increase HIV testing among their male partners. The study will recruit adult women from antenatal care and post-partum clinics in Kisumu. Each participant will be randomized to either receive two HIV self-tests or to receive counseling referring their partner to HIV testing (standard of care). Over a 3 month period, we will obtain information from study participants on how many sexual partners they offered the tests to, the receptivity of their sexual partners to using self-tests, and the incidence of any adverse events. We will compare partner testing rates in intervention and control groups.
This is a multicenter, single arm, 96-week open-label study of the safety and virologic efficacy of fixed dose combination Dolutegravir/Lamivudine/Abacavir (DTG/3TC/ABC FDC) initiated during acute HIV infection (AHI).
P1106 is Phase IV prospective pharmacokinetic (PK) study of low birth weight infants who are receiving or will be receiving as part of clinical care nevirapine (NVP) prophylaxis, tuberculosis (TB) prophylaxis or treatment and/or combination antiretroviral (ARV) treatment containing lopinavir/ritonavir (LPV/r). The study is designed to describe the pharmacokinetics and safety of NVP, INH, RIF, and LPV/r in these infants receiving the drug(s) as part of clinical care.
Cardiovascular disease (CVD) has emerged as a leading cause of morbidity and mortality in HIVinfected individuals. The precise mechanisms underlying this increased cardiovascular risk remain to be elucidated. Platelet hyperreactivity and increased platelet-monocyte aggregation (PMA) are found in HIVinfectedpatients and may contribute to the excess cardiovascular risk as platelets play a key role in the onset and progression of atherosclerosis and in acute cardiovascular events. In addition, HIV-infected individuals frequently suffer from persistent immune activation and inflammation. In a crosssectional study the investigators recently showed that individuals using a regimen containing the integrase inhibitor raltegravir have reduced platelet hyperreactivity and PMA compared to other antiretroviral regimens. Other recent studies showed that raltegravir is associated with decreased immune activation. Due to the inherent limitations of cross sectional studies, the investigators aim to expand our findings in an intervention study. The investigators will conduct a randomized control trial where the investigators switch patients to a integrase containing treatment regimen to assay possible changes in platelet function and persistent immune activation. Knowledge gathered in the proposed study can help understand and prevent cardiovascular disease in patients treated for a HIV infection by reducing platelet hyperreactivity and persistent immune activation.
Elevated on-treatment platelet reactivity is an independent risk factor of major adverse cardiovascular events following percutaneous coronary intervention or ACS. People living with HIV patients have a higher risk of recurrent events after ACS than people without HIV. The investigators hypothesized that this increased risk is driven by higher platelet reactivity. Using a nested case-control study design, HIV-infected and HIV-uninfected patients with a first episode of Acute Coronary Syndrome (ACS) treated with percutaneous coronary intervention were matched for age, sex, known diabetes mellitus and anti-platelet therapy. The primary end-point was the residual platelet reactivity (RPA) on dual antiplatelet therapy assessed by light transmission aggregometry (LTA, 20µM ADP). The study was conducted in a two large public university hospitals in central Paris, France.
The purpose of this study is to evaluate the efficacy of a web-based tailored intervention to support persons living with HIV (PLHIV) manage the demands inherent to their health condition, particularly as regards to the adoption of health behaviours such as being physically active, following a healthy diet and quitting smoking.

Tanzania launched a National Strategy for scaling-up voluntary medical male circumcision in 2010, and aims to circumcise 2.8 million males by 2015. In September 2009, Jhpiego's Maternal and Child Health Integrated Program (MCHIP) launched a PEPFAR-funded voluntary medical male circumcision (VMMC) program which has circumcised over 110,000 males in Njombe and Iringa regions by June 2012. In line with the national strategy, the target age for the program was 10-34 years, but 80% of clients were aged 10-19 years. There is an urgent need to increase the proportion of older men (aged 20 years and above) who become circumcised, to have greatest impact on the HIV epidemic.
The development of surrogates to predict HIV prevention product safety and efficacy is a high priority. An ex vivo challenge model is one such promising surrogate. Colonic tissue exposed to rectally applied microbicides in vivo and then challenged with HIV in the lab showed significant reduction in HIV replication when compared to tissue exposed to placebo gel. Currently, the ex vivo challenge model for ectocervical and vaginal tissue is under development at the Dezzutti lab at the Magee Womens Research Institute in Pittsburgh, PA. Currently the Reproductive Infectious Disease Research Group is conducting a study designed to answer important questions about the ex vivo challenge model:which HIV virus is the best to use in the laboratory and what is the best indicator of HIV infection. The proposed study delineated here will investigate the effect of BV, HSV and contraceptive use on the model . There will be two arms to the study; the first will investigate the impact of HSV and BV status and the second, contraceptive use. Vaginal and cervical biopsies will be collected from participants for the ex vivo challenge model.
