Filter by:Co-morbidities, including low bone mineral density, increased visceral adiposity and chronic kidney disease (CKD) are frequent in people living with HIV, and may be driven by ongoing inflammation and immune activation. Initiation of ART reduces inflammation and immune activation and is associated with changes in bone and renal biomarkers and gut microbiota. Investigators hypothesise that changes in gut microbiome when starting antiretroviral therapy correlate to changes in bone and renal biomarkers and wish to explore possible mechanisms linking these by investigating changes in markers of inflammation and immune activation.
Human immunodeficiency virus (HIV) infection continues to be a pandemic, Mexico has around 184,000 people infected by this virus. A common metabolic problem for these patients is oxidative stress (OS), which has been related with the progression of the disease and the presence of comorbidities. Pomegranate is a fruit rich in antioxidants, which potentially can inhibit or reduce deleterious metabolic compounds resulting from OS; however; it has never been tested in patients infected with HIV. The present project was done in patients HIV+ from state of Hidalgo in order to see the effects of microencapsulated red pomegranate juice (MRPJ) and ascorbic acid (AA) on antioxidant activity and lipid peroxidation both biomarkers of oxidative stress. Sixty subjects were recruited, 30 HIV positive (HIV+) and 30 HIV negative (HIV-). Three subgroups (n=10) were formed from each group: 1) supplemented with (1g/d) MRPJ; 2) supplemented with 1g/d AA; and 3) control group (unsupplemented). The intervention lasted 90 days and blood samples were taken four times: at the beginning and every 30 days. Antioxidant activity in the blood serum was measured by the DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS + (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) methods while lipid peroxidation by malondialdehyde (MDA) levels which was measured by TBARS method. The baseline results showed a significant decrease of antioxidant activity in HIV+ groups compared to the HIV- groups, although there was no significant difference in lipid peroxidation, as measured by MDA assay levels. Several studies suggest that the reduction of antioxidant activity is a consequence of the infection and the antiretroviral treatment, although the organism tries to reestablish it unbalance it usually fails, thus (OS) is significant in these patients. The groups that received AA had antioxidant activity greater than the MRPJ treated. MRPJ treatment, however, the groups that received MRPJ had significantly reduced lipid peroxidation. Reduced lipid peroxidation could have more beneficial effects on HIV+ subjects since the reduction of markers of OS, such as lipid peroxidation, has been associated with reductions in the risk of death from HIV.
This study will look at virologically suppression of patients with HIV who receive pharmacist or case management care.
This protocol describes the Cohort Assessment phase of an R34 pilot intervention trial of a Peer Navigation (PN) intervention tailored to the needs of HIV-positive MSM in rural Mpumalanga province South Africa. The PN intervention to be adapted, I-Care, has been implemented among HIV-positive men and women in the general population in North West province, South Africa, by members of this research team.
This protocol is for the long term follow-up study of "Comparing Food and Cash Assistance for HIV-Positive Men and Women on Antiretroviral Therapy (ART) in Tanzania", a 3-arm randomized controlled trial led by Professor Sandra McCoy at the University of California Berkeley and Dr. Prosper Njau at the Tanzanian Ministry of Health and Social Welfare. The investigators will determine the long-term effectiveness of short-term incentives for ART adherence and retention in care. The study will also determine whether incentives can also be used to re-engage PLHIV with HIV care after they have fallen out of care.
In this prospective longitudinal study we aim to assess how immunologic and viral aspects of the human immunodeficiency virus (HIV) viral reservoir, established during early HIV infection and responsible for viral rebound at treatment interruption, evolve in individuals who start combination anti-retroviral therapy (cART) during acute seroconversion. Recently infected patients will be selected based on Fiebig staging for an in depth sampling protocol at different timepoints during a 2 year follow up period. Colonbiopsies, lymphnode resection, lumbar puncture, leucapheresis and repeated peripheral venous blood-draws will be performed. Immunological, virological and genome expression analysis will be performed on the gathered samples.
R34-funded study to pilot test an intervention to improve coping with discrimination and adherence among Latino men who have sex with men (MSM) living with HIV. The proposed research aims to modify and refine Siempre Seguiré, a culturally congruent cognitive behavior therapy group intervention for HIV-positive Latino men who have sex with men (LMSM), to include strategies for ART adherence and retention in HIV care; and to conduct a small randomized pilot of Siempre Seguiré to examine feasibility and acceptability, as well as to explore preliminary effects on coping responses to discrimination and antiretroviral treatment adherence among LMSM living with HIV.
The study will evaluate the effect of implementing a family-centered care (FAM-CARE) program (where all HIV-positive family members are seen together as a unit and receive care together) on viral suppression and retention in HIV-positive children <15 years through enrollment of a prospective cohort of 660 HIV-positive children and their caregivers at sites that were randomized to either implement the family-care program (intervention sites) or continue the current standard of care (control sites).
This study will provide data on the switch from a protease inhibitor or efavirenz to the new formulation of raltegravir (RAL) dosed once daily. The study group consists of patients with metabolic risk factors and co-morbidities, in need of optimization of their current ART to minimize the drug-related metabolic side effects as standard of care. The primary objective of this study is to investigate whether switching a protease inhibitor (PI) or efavirenz to raltegravir once daily reduces liver fat in patients who are overweight or obese and have at least one metabolic syndrome component. For this purpose, the liver fat content will be analyzed using the proton magnetic resonance spectroscopy. In addition, the aim is to clarify the change in the body composition and metabolism in this study group. For this purpose the visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) volumes will be measured and subcutaneous tissue samples will be collected for future analyses of adipose tissue function.
Efficacy of etravirin + raltegravir dual therapy was showed in the ANRS 153 ETRAL protocol, in HIV-1 seropositive patients. The use of these two drugs avoids the use of nucleoside reverse transcriptase inhibitors and protease inhibitors, with a real benefit in older patients, who increasingly present contraindications to these drugs' families. The disadvantage of this strategy is twice daily (BID). Pharmacological data suggest that etravirine once a day and raltegravir once a day may provide the same virological efficacy. The objective of our study is to evaluate the ability of ETRAL QD (etravirine 400 mg x1/day + raltegravir 800 mg x1/day) to maintain virologic success at week 48 (W48), after switch, in HIV-patients under ETRAL BID (etravirine 200 mg x2/day + raltegravir 400 mg x2/day). Virological success is defined as absence of virological failure, and virological failure is defined as two consecutive plasma viral loads >50 cp/ml over 2-4 weeks, or one plasma viral load >400 cp/ml. This study will be a multicentric data collection. Data will be collected at W0 (patient characteristics, plasma viral load) and then at W4, W12, W24 and W48 (plasma viral load). If stopping strategy, the reason for stopping will be documented. 125 patients will be included in the six participating centers. Data will be centralized at Pitié-Salpêtrière hospital, Paris, with an anonymized e-CRF.
