Filter by:The purpose of this study is to determine if the combination of atazanavir and raltegravir taken together is safe and effective in the treatment of human immunodeficiency virus (HIV).
The purpose of the study is to examine the effects of switching from antiretroviral combinations that includes efavirenz (Sustiva®), lopinavir/ritonavir (Kaletra®) or atazanavir/ritonavir (Reyataz®/Norvir®) in individuals experiencing side effects from one of these agents, and replacing these with a new HIV medication called Darunavir also given with ritonavir (Norvir®). The study will primarily investigate the effect of change in medication on the subjects viral load (the levels of the HIV virus in the blood), on immunological parameters (CD4 count) and on other safety parameters (such as cholesterol) and also quality of life.
A study to evaluate the safety, tolerability and efficacy of once daily Raltegravir compared to twice daily raltegravir when each is given in combination with TRUVADA™ in treatment-naïve human immunodeficiency virus (HIV)-infected patients.
The purpose of this study is to study the safety, tolerability and pharmacokinetics of rifabutin dosing with lopinavir/ritonavir tablets in healthy volunteers.
This study will evaluate the effectiveness of pioglitazone in reducing liver fat content in patients with HIV and hepatitis C virus (HCV) infections. Fatty liver and accompanying insulin resistance in patients with HIV and HCV co-infections is associated with inflammatory changes, liver fibrosis and a poorer response to HCV treatment. Pioglitazone is a drug that helps to reduce the body's resistance to insulin. It is approved by the Food and Drug Administration to treat diabetes. Patients with HIV and HCV co-infections who have hepatic steatosis (fatty liver) may be eligible for this study. Candidates are screened with a medical history and physical examination, blood and urine tests, magnetic resonance imaging (MRI) of the liver to measure liver fat and, if needed, a liver biopsy to confirm the diagnosis of liver steatosis. - Participants are randomly assigned to take either pioglitazone therapy or placebo for 48 weeks. This is followed by a second 48-week treatment period in which all participants take pioglitazone. - There are approximately 12 visits during the 96 weeks of the study. Participants will receive a physical assessment, blood and urine tests at each visit. In addition, periodic assessments of dietary habits, body composition, oral glucose tolerance testing, and health related quality of life questionnaires will be completed. - A repeat MRI of the liver is performed at 48 weeks and at the end of the study to evaluate any potential changes in liver fat and inflammation. In addition, there is a follow-up liver biopsy at 48 weeks and an optional liver biopsy at 96 weeks.
The purpose of this study is to evaluate and compare the efficacy of immediate antiretroviral therapy versus 2 month deferred anti-Tb therapy upon the clinical course of tuberculosis and HIV infection in patients with AIDS and active tuberculosis.
To explore the hypothesis that the use of Lopinavir/ritonavir will be associated with improved CD4 immune reconstitution in volunteers who fail to demonstrate a significant CD4 cell increase (while on their first antiretroviral treatment regimen) despite sustained viral suppression by a non-Lopinavir/ritonavir-containing regimen
This project, called PHIDISA I, will screen uniformed personnel of the South African National Defense Force (SANDF) and their registered family members for HIV, hepatitis B and C, gonorrhea, syphilis, and chlamydia to determine the incidence and prevalence of these sexually transmitted diseases. It will identify people who may be eligible to participate in clinical trials for preventing or treating HIV disease and will provide information that will be helpful in developing policy and better care for people affected with HIV and other diseases. This project is part of the South Africa-U.S. PHIDISA Programme-a collaboration between the South African Military Health Service (SAMHS) of the SANDF, the U.S. Department of Defense, and the U.S. National Institutes of Health-to help prevent HIV transmission among South African military and civilian employees and their families. Uniformed SANDF personnel or their family members who are eligible for health services from the SAMHS may enroll in the study. Participants visit the clinic every 6 months for up to 5 years for the following tests and procedures: - Fill out a demographic information questionnaire - Fill out a HIV risk assessment questionnaire - Fill out a quality of life questionnaire - Blood test - Urine test - Review of test results and counseling session with a doctor or nurse Patients who test positive for HIV have a physical examination and additional blood draws. ...
This study, conducted in Bamako, Mali (West Africa), will collect blood and sputum samples to establish normal values for laboratory test results among Malians. Researchers are starting a new initiative to study HIV and tuberculosis in Africa, using Mali as a model country. In order to perform these studies, the scientists need to know what constitutes normal laboratory values among the population. People in developing countries may have dramatically different laboratory values from those who live in developed countries, and there is currently little information available to distinguish normal from abnormal results in Malians. This study will establish normal ranges that will provide a basis for future HIV and tuberculosis research in Mali. Additionally it will provide blood and sputum samples to researchers to study different scientific questions related to HIV and Tuberculosis infection. Healthy volunteers and people infected with HIV or tuberculosis, or both, who are 18 years of age or older and who live in Bamako, Mali, may be eligible for this study. Candidates are screened with a medical history, physical examination, and blood test. Participants provide a blood or sputum sample, or both, for laboratory analysis. Blood is collected through a needle inserted into an arm vein, and sputum is collected by having the participant cough deeply and spit in a cup. Participants may agree to provide samples one time only or on a returning visit basis. Returning visits may be scheduled daily or weekly. Subjects may continue to participate for the duration of the 4-year study, provided their medical history and physical examination are updated once a year.
The development of a safe and effective vaccine for HIV is the subject of intensive world-wide research. Various approaches are being investigated in monkey models and humans. This is a randomized, double-blind trial to evaluate the safety and immunogenicity of a candidate preventative human immunodeficiency virus (HIV) vaccine strategy in 24 healthy adult Thai volunteers with no identifiable risk behaviour for HIV-1 infection. Volunteers will receive three "priming" vaccinations at weeks 0, 4 and 8 (pHIS-HIV-AE, a DNA vector delivering AE clade HIV-1 genes). This will be followed at week 12 by single "boost" vaccination (rFPV-HIV-AE, non-replicating, recombinant fowlpox virus vector delivering the same HIV-1 genes). Safety and immunological monitoring will continue to 52 weeks
