Filter by:This randomized controlled trial is going to evaluate whether an intervention consisting of a smartphone application to assist smokers living with HIV to quit in combination with CO self-monitoring compared to stop smoking counselling by physicians during usual care results in higher self-reported and biochemically verified smoking cessation rates at 6 months. .
This prospective, two-site, two-arm, randomized, single-blind, placebo-controlled trial will examine the safety and pharmacokinetics (PK) of a polyurethane tenofovir disoproxil fumarate (TDF) vaginal ring when used continuously for 84 consecutive days by sexually active women. The primary objective is to assess the safety of TDF vaginal rings when used continuously for 84 days by healthy, HIV-uninfected, sexually active women, as compared with a placebo vaginal ring.
With aging of the persons living with HIV, cardiovascular diseases now account for substantial mortality and morbidity. Stroke frequency grows exponentially with aging and its incidence doubles every decade over 55 years of age. The prognosis of ischemic stroke depends mainly on the care in Stroke Units in the acute phase of the disease (thrombolysis/thrombectomy). It is important that HIV patients are referred to these units in the first hours of a stroke and not to their infectious disease units which is a loss of chance. It would also be important to know whether HIV patients need specific protocols for stroke emergency management. The study aims to compare the functional prognosis after the first occurrence of an ischemic stroke, in patients admitted to a Stroke Unit, whether they are infected or not infected by HIV.
This study will investigate the pharmacokinetic of evotaz (atazanavir/cobicistat) and microgynon (ethinylestradiol/levonorgestrel ) when administered alone and together. There will be two study arms, who will take the medications in different orders: GROUP 1: Microgynon 30® for 21 days, Followed by Microgynon 30® for 21 days plus Evotaz® for 14 days, Followed by Evotaz® for 14 days GROUP 2: Evotaz® for 14 days followed by 7 days wash-out, Followed by Microgynon 30® for 21 days plus Evotaz® for 14 days, Followed by Microgynon 30® for 14 days (participants may chose to complete a 21 day pack). The total duration of the study is 57 days (+screening and follow up visits) and patients will have 3 intensive pharmacokinetic days on days 14, 35 and 56.
Management and treatment of older persons living with HIV (PLWH) (≥ 40 years old) is becoming increasingly more complex as a majority is greater than 40 years old. This proposal will conduct a prospective controlled intervention trial to assess the quantitative and qualitative effects of a monitored aerobic/resistance exercise (EXS) program compared to a social-interaction stretching (SIS) program on brain health (neuropsychological performance testing and neuroimaging measurements) in older PLWH. These results could influence public health policy by encouraging PLWH to adopt a more physically active lifestyle and stimulate the development of effective EXS programs for older PLWH.
The purpose of this study is to develop pilot data on the potential efficacy of computer-based cognitive training or the combination of computer-based cognitive training with transcranial direct current stimulation (tDCS) in improving cognitive function in persons with HIV-related mild neurocognitive disorder (MND).
The purpose of this research study is to find out how the drugs Truvada® (tenofovir/emtricitabine), Isentress® (raltegravir), Reyataz® (atazanavir), Sustiva® (efavirenz), and Selzentry® (maraviroc) get into the intestines and the female genital tract. All of these drugs are very effective at reducing the number of HIV viruses in the blood, however it is unknown how the drugs move around inside tissues where HIV might be hiding. This study will determine specifically where in the tissue the drug and the HIV are located through the use of a new technology that takes creates a picture of the tissue. This information will help scientists determine the best way to make new drugs to target the hidden HIV in tissue.
Data on the progression of liver fibrosis in patients co-infected with HIV taking effective suppressive antiretroviral therapy with no fibrosis or mild-to-moderate fibrosis at baseline are scarce. This uncertainty is reflected in lack of clear guidance on the need for earlier (than F3-F4) treatment in co-infected patients. Within our hepatitis C/HIV co-infection project in Cambodia, the investigators have the opportunity to monitor for short-term fibrosis progression in a cohort of co-infected patients with initial no-to-moderate fibrosis being identified during another ongoing study (HCV-Epi) and contribute relevant data to aid the risk/benefit analysis of postponing HCV treatment in HIV/HCV co-infected patients with initial fibrosis stage F0-F2. The HCV-Monitoring study is a mono-centric prospective cohort study proposing a standardized follow-up (clinical, biological and imaging) to monitor for progression of hepatitis C disease in all patients with HIV infection (on anti-retroviral treatment or not) of Sihanouk Hospital Center of Hope (Phnom Penh, Cambodia) who have chronic HCV infection with GT-1, -2, -3 or -6 but are not considered in immediate need of HCV treatment. All adult HIV-infected patients of the cohort (on ART or not yet on ART) of Sihanouk hospital Center of Hope who are identified during the HCV-Epi study having chronic HCV infection (all genotypes) and considered not in immediate need of HCV treatment (= Fibrosis stages F0-F2 and no clinical signs of extra-hepatic disease) will be considered for inclusion and invited to participate. Approximately 70 HCV/HIV co-infected patients with no-to-moderate hepatic fibrosis will be enrolled in this study. Beyond the baseline visit (HCV-Epi), follow-up visits are planned at 6, 12, 18 and 24 months. These patient visits will comprise of a history taking and physical examination focused on hepatic disease and blood sampling for basic hematologic and hepatic function parameters. Additionally, patients will be referred every year for ultrasound and transient elastography measurements and sampling for some additional liver function tests and measurement of HCV-RNA viral load.
This study is designed to evaluate specific factors in mitochondria that may precipitate premature aging and physical weakness in HIV patients. Angiotensin receptors 1 and 2 (AT1R and AT2R) are found in virtually every cell type. This study will evaluate how the relationships among these receptors in immune and skeletal muscle cells change with HIV, and how these changes might trigger mitochondrial dysfunction, declines in muscle strength, and cellular decline in people living with HIV.
Triple antiretroviral regimens have greatly improved the prognosis of patients living with HIV (PLHIV). Patients virologically controlled and having a good immune restoration can have a life expectancy close or equal to that of people not infected with HIV.[1] However, this is under the condition of a "lifetime" maintenance of an undetectable plasma viral load (pVL) (<50 cp/ml). On the other hand it is well established that aging increases comorbidities among PLHIV and the burden of co-medications.[2] This also has the consequence of frequent drug-drug interactions. In this context it is important to decrease pills burden, side-effects and drug-drug interactions, while maintaining undetectability. Currently, there is a strong interest for medical research to validate lightened regimens (i.e. bithérapies [3-7] and monothérapies [8,9], particularly in a maintenance strategy, with the primary objective of reducing burden of pills and side effects. Several monotherapy trials using a boosted protease inhibitor (PI/r) showed high level of viral suppression, even if this proportion was not always non-inferior to maintaining a triple therapy. [8,9] Fortunately, when virological failure occurred under monotherapy virologic suppression was easily restored by the addition of two NRTI. Patients who are most likely to maintain viral suppression under a reduced scheme are those that have a high nadir (> 100 CD4 / mm3), no previous AIDS event and a sustained virologic suppression (>12 months). Monotherapy is the option that best reduces the burden of pills and the risk of side effects or drug-drug interactions. It must be considered using very powerful molecule that harbor a strong binding to its ligand in order to minimize the risk of selecting resistant mutants in the case of virologic failure. To be as simple as possible in its use, it must be a single agent administered as a single dose once a day and not boosted if possible. The molecule must have very good tolerance. Finally, to be effective in viral sanctuaries this molecule should have a good (or sufficient) diffusion to ensure effective Cmin on wild viral strains. Dolutegravir meets all these exigences.[10] In addition, our team recently presented results of a pilot study showing that the switch of a successful combined antiretroviral regimen to dolutegravir monotherapy maintained undetectable viral load (<20 cp/ml) after a median of 7 months (range 6.5-10 months).
