Filter by:It is well known that HIV-infected subjects frequently experience hyperlipidemias, insulin resistance, and visceral adiposity, which are known to increase the risk of atherosclerosis. Several cohorts have shown an increased risk of heart disease in people with HIV. The effect of HIV treatment versus HIV itself on the incidence of heart disease is unclear. In this study the investigators will assess the effect on carotid IMT of the initiation of antiretroviral combinations that are known to have a minimal effect on lipids and insulin resistance. We will also assess the changes in several inflammation and cardiovascular markers,as well as endothelial activation markers,and how these changes relate to therapy-induced changes in immunologic, virologic and metabolic markers.
Effective therapy for human immunodeficiency virus (HIV) infection has markedly prolonged survival in infected individuals. As a result, other diseases are now becoming clinically significant. Approximately 30% of HIV infected patients are co-infected with hepatitis C virus (HCV) which is now the leading co-morbid disease in co-infected individuals. The histologic severity and natural history of HCV has been reported to be accelerated in those co-infected with HIV. It is hypothesized that 1) the severity and progression of HCV disease is related to the immune competence of the individual, 2) immune restoration associated with HIV therapy may further accelerate the progression of HCV disease which may explain the marked increase in HCV related morbidity and mortality observed in recent years, and 3) the virologic response to anti-HCV treatment is directly related to the degree of immunologic competence. The specific aims of the proposal are: 1) To obtain, through multi-disciplinary didactic teaching, the necessary skills of clinical research design, data collection, data analysis, and biostatistical methods and 2) To study the impact of HIV disease on HCV, the effect of the immune function and immune restoration during HIV therapy on the natural history of HCV, and the efficacy of HCV treatment in HIV co-infection.
The purpose of this study is to evaluate the safety of and immune response to an experimental DNA HIV vaccine followed by boosting with an experimental modified vaccinia HIV vaccine (MVA) in HIV uninfected adults.
The investigators are proposing that energy specific electromagnetic radiation of the central nervous system, the viscera and the endocrine system has the potential to enhance the immune system; thereby enhancing the production of killer cells to fight and destroy the human immunodeficiency virus.
The goal of this trial is to demonstrate that new treatments are as effective as a reference triple-agent regimen in driving plasma viral load below the detection limit early during treatment (16 weeks). These simplified treatments involve fewer tablets and intakes, fixed-dose combinations, and also radically new strategies such as boosted protease inhibitor and tenofovir.
HIV patients treated with Highly Active AntiRetroviral Therapy (HAART) show significant metabolic symptoms, such as lipodystrophy, dyslipidemia, and insulin resistance. A possible contribution to these symptoms in HIV/HAART is a decrease in mitochondrial function, resulting in a decreased fatty acid oxidation. A combined regime of aerobic and resistance training has been demonstrated to increase lean body mass and reduce overall fat and truncal fat and the levels of triglyceride and LDL cholesterol.
The main purpose of this protocol is to study the effect of an HIV medication, Kaletra (lopinavir/ritonavir), on buprenorphine in non-HIV infected people who have been receiving the same dose of buprenorphine for at least 3 weeks. Study Hypothesis: Kaletra (lopinavir/ritonavir) will increase buprenorphine plasma levels without any significant clinical effect on the subject or need for dose adjustment.
This study is to establish the clinical sensitivity of the Chembio Diagnostics Systems, Inc. Clearview COMPLETE HIV 1/2 Assay and Clearview HIV 1/2 Stat-Pak Assay (Clearview HIV tests) in pediatric subjects who are between 12 and 17 years of age. A minimum of ten (10) known HIV-positive participants will be tested.
Advocacy groups have voiced concerns about the ethics of some of tenets of the CDC's new HIV testing recommendations for the healthcare setting. Three concerns are paramount: (1) the opt-out approach to HIV testing can potentially be coercive and not truly voluntary; (2) by replacing informed consent with general consent for medical care, test participants might not know or be adequately informed of the benefits and consequences of testing; and (3) eliminating HIV prevention counseling from the HIV testing process presumes that test participants are aware of how to prevent an HIV infection, which might not be correct. This study involves conducting interviews of HIV advocates who are raising these concerns, surveying outpatient and emergency department clinical providers about their beliefs and opinions regarding the tenets of the new guidelines, and then conducting a multi-center, randomized, controlled trial in which the ethical concerns of opt-out vs. opt-in testing are directly compared. We will conduct a multi-center, randomized, controlled, trial whereby patients will be surveyed on their perspectives and perceptions regarding opt-out or opt-in rapid HIV testing. We will survey the participants regarding their perception of coercion, their understanding of the elements contained in the informed consent process, their HIV risk factors, and their knowledge of HIV prevention. We will evaluate whether or not the CDC-recommended approaches regarding opt-out testing, consent, and decoupling of prevention counseling are supported. If there are no differences regarding these ethical concerns between testing approaches, then the opt-out approach would be considered not to be inferior to the opt-in approach.
Human immunodeficiency virus infection and highly active antiretroviral therapy (HAART) are associated with an increased risk of cardiovascular disease: a wide range of alterations in lipid and glucose metabolism has been increasingly recognized in HIV patients treated with HAART. Few data are available on the effects of antihypertensive treatment on cardiac morpho-functional characteristics and metabolic parameters in HIV patients. Aim of the study is to assess the effects of chronic therapy with angiotensin receptor blocker(candesartan)or calcium channel blocker (lercanidipine)on metabolic profile and cardiac remodelling in HIV hypertensive patients.
