Filter by:This study will investigate HIV infection and associated conditions by monitoring infected patients. The study will also serve as a means for recruiting HIV-infected individuals to NIAIDs ongoing clinical and laboratory studies and supporting the institute s infectious disease training program by providing Infectious Disease fellows with ongoing training in the management of HIV infection. People 18 years of age and older with suspected or confirmed HIV infection who live in the Washington, D.C., metropolitan area may be eligible for this study. Physician referral is required. Participants come to the NIH Clinical Center a minimum of once every 3 to 4 months for evaluation with a physical examination; blood tests for research purposes, safety, immune status and viral load; and response to any treatment they may be receiving. Other procedures, such as a biopsy, are done only as needed for standard medical practice, and informed consent is obtained before any such procedure is done. Treatment offered is consistent with standard medical practice; no experimental treatments are offered under this protocol. ...
Subjects with HIV who have viral suppression on current regimen but also have side effects/intolerance will change their current regimen to a combination of Raltegravir and Atazanavir and be monitored for viral and immunological response and quality of life.
HIV induced altered representation and function of regulatory T cell subsets (NKT and Treg cells) impair the protective T cell response against M.tuberculosis and disrupts LTBI, thus facilitates faster progression and development of severe forms of clinical TB in HIV-TB co-infection.
To assess the HIV resistance rate to variable antiretroviral agents in Taiwan, especially in patients with treatment failure, and to know the correlation between the drug resistance pattern and the HIV subtype, we will enroll a total of 150~200 HIV-1-infected subjects to perform genotypic resistance testing and try to establish facility of phenotypic resistance testing.
Data from this study will provide the first information how the innate immune system may be altered in HIV-HCV and HIV-HBV co-infected individuals, and describe Toll-like receptor changes with HIV co-infection therapy.
Human immunodeficiency virus/Hepatitis B virus (HIV/HBV) co-infections are frequently observed due to shared routes of transmission, with reported figures indicating 6-9% of HIV-infected individuals in developed countries are chronically infected with HBV. HIV infection impacts on the natural progression of HBV infection, increasing levels of HBV replication and the risk of liver-associated mortality. Liver diseases associated with HBV are affected by the antiviral drugs used for HIV infection (toxic side effects), the current immune function in the patient, by improvements in the immune system brought about by control of the HIV infection, and by the development of resistance to the antiviral agents used for both the hepatitis B and the HIV infection. Tenofovir (TDF) is a newer antiviral drug that is frequently used for HIV infection and is also highly active against hepatitis B; however it is still unknown whether resistance to TDF will eventually develop and how this will affect the long-term outcomes
Human immunodeficiency virus/Hepatitis B virus (HIV/HBV) co-infections are frequently observed due to shared routes of transmission, with reported figures indicating 6-9% of HIV-infected individuals in developed countries are chronically infected with HBV. HIV infection impacts on the natural progression of HBV infection, increasing levels of HBV replication and the risk of liver-associated mortality. Liver diseases associated with HBV are affected by the antiviral drugs used for HIV infection (toxic side effects), the current immune function in the patient, by improvements in the immune system brought about by control of the HIV infection, and by the development of resistance to the antiviral agents used for both the hepatitis B and the HIV infection. Co-infection with HBV increases the risk for hepatotoxicity in those individuals receiving highly active antiretroviral therapy (HAART) for their HIV infection. This study will recruit patients who are co-infected with HIV and HBV, and are currently taking or who are about to commence HAART. The study cohort will include HIV-HBV co-infected individuals from the Alfred Hospital, the Royal Melbourne Hospital and high case load GP clinics who are referred to the Alfred Hospital. The aim of the study is to investigate chronic hepatitis B and its impact on the progression of liver disease in HIV-infected persons receiving HAART. This will be achieved by 6 monthly assessment with medical history, physical examination, bloods for markers of liver disease and hepatitis B activity and completion of questionnaires to measure adherence and alcohol use.
The medicines used to treat HIV can suppress but cannot kill all the virus in the body. A small amount of virus remains at low levels in the part of the blood called the plasma. It is of crucial importance to identify the source of the residual virus in patients receiving antiretroviral therapy. The purpose of this study is to investigate whether the source of low level plasma virus is from latent (old) infection or ongoing (new) infection. MK-0518 is a investigational drug, which means that is not yet FDA approved, that works in a different way to other anti-HIV medicines to help kill the virus. We hypothesize that addition of MK-0518 to a stable anti-HIV regimen will reduce the viral load further in patients with undetectable plasma virus.
The hypotheses of this study are: 1. Ondansetron will show a decrease in cocaine use from baseline in individuals with HIV who are cocaine using. 2. Ondansetron will show a decrease in cravings from baseline in individuals with HIV who are cocaine using. After informed consent and screening, HIV infected individuals who are cocaine dependent and qualify for the study will be offered ondansetron 4mg BID for six weeks in an open label format 4mg BID has been found to have efficacy compared to placebo. At screening and then at each visit, they will be asked to provide urine and a drug of abuse screen will be conducted to assess for cocaine. They will be asked to detail their recent cocaine use in the last month and then will be given a visual analog scale to assess their craving for cocaine. They will be asked to return weekly for 6 weeks to receive a week's supply of ondansetron and to give a urine sample that will test for cocaine. They will fill out a time line follow back for the past week and asked to assess their craving for cocaine on a visual analog scale.
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.
