Filter by:The Project ÒRÉ intervention is a half-day community-based HIV/STI intervention program for friendship groups of adolescents that is tailored to African American culture. The four participating community sites will be assigned to either the Project ÒRÉ intervention or a standard health promotion program. Sexually experienced African American adolescent females will recruit members of their friendship group for the five-hour program. All participants will complete questionnaires before and immediately following the programs and another one 3 months later. Immediately following the program some of the Project ÒRÉ groups will also participate in a focus group to provide feedback about the program.
The purpose of this study is to determine the best time to begin anti-HIV treatment in individuals who have HIV and tuberculosis (TB). Study hypothesis: Immediate antiretroviral therapy (ART), initiated after approximately 2 weeks of TB treatment, will reduce the frequency of other AIDS-defining illnesses and death in HIV-infected participants being treated for TB by at least 40% at week 48 when compared to deferred ART, initiated at after 8-12 weeks of TB treatment.
The purpose of this study is to determine if implementing a policy of widespread INH (Isoniazid) prophylaxis therapy in HIV-infected patients with access to antiretroviral therapy reduces the incidence of active TB disease in the HIV clinic population.
The purpose of this study is to compare the development of abnormal cell growth or cancer in the anal region of individuals who are receiving one of two different anti-HIV treatment strategies.
The purpose of this study is to determine the safety of two recombinant HIV vaccines in HIV infected young adults on stable anti-HIV therapy.
This protocol is a study of HIV+ young people who were identified as having certain HIV-1 specific T-cell responses and genetic markers while previously enrolled in the 5-year longitudinal adolescent study, "REACH." Blood samples will be collected, a medical and medication history and physical examination will be performed every 6 months for a total of 2 years.
This study will examine abnormalities in mitochondria (energy-producing machinery of cells) and in genes related to mitochondria in the blood cells, muscle, and fat of HIV-positive patients who are taking nucleoside reverse transcriptase inhibitors (NRTIs) and in patients not currently taking HIV medications, and compare the results to healthy volunteers. Many patients with HIV infection take NRTIs to help control the infection. These medications may damage cell mitochondria, possibly causing side effects such as fatigue. This study will explore the relationship between changes in mitochondria and related genes and patient reports of energy level, mood and quality of life. Healthy volunteers and HIV-infected patients between 18 and 55 years of age may be eligible for this study. Healthy volunteers must test negative for the HIV antibody. HIV-positive patients must have been diagnosed positive for at least 1 year. Patients who are taking antiretroviral therapy must have been taking the same drug regimen (with at least two NTRIs and no protease inhibitors) for at least 3 months. HIV positive patients not taking antiretroviral medication must not have had antiretroviral therapy for at least 1 year. Candidates are screened with a medical history, brief physical examination, blood and urine tests, and questionnaires related to mood and energy. Qualified volunteers will undergo the following procedures during three or four study visits: Visit 1 Complete history and physical examination, blood tests, and questionnaires about energy level, mood, and quality of life. Visit 2 Muscle and fat biopsy: Before the biopsy, blood is drawn to check blood counts and to test for pregnancy in women who can become pregnant. The biopsy is done on an outpatient basis in the operating room. The site of the biopsy (an area on the upper arm or upper leg) is numbed with an injection under the skin. A 1-inch incision is made over the muscle to be biopsied and a small sample of muscle tissue and small sample of fat are removed. The incision is then closed and bandaged. Following the biopsy, you will be monitored for about 4 hours in the clinic. Strenuous physical activity should be restricted in the week following biopsy to allow healing. Visit 3 Examination of biopsy site and possible apheresis: The biopsy site is examined for healing. Apheresis may be scheduled for this visit or for an extra visit between the biopsy and the final visit. This procedure for obtaining white blood cells for study is optional. For apheresis, blood is withdrawn from a needle placed in a vein in the arm and the white cells are separated from the rest of the blood. The white cells are extracted and the red cells and plasma are then returned to the body through a second needle.
A number of factors influence HIV-positive adolescents' acceptance of and willingness to continue taking anti-HIV medicines. These factors include mental health and substance abuse issues, barriers such as lack of medical insurance, and cognitive-behavioral barriers (such as a person's impression of the impact of the medicines on his/her health and a person's sense of his/her ability to continue taking the medications prescribed). The purpose of this study is to use a survey to determine how common specific barriers are that prevent HIV positive adolescents from taking their anti-HIV medicines and if those barriers cluster together. The information collected will be used to develop and validate a schema for classifying HIV medication adherence by barriers to adherence or clusters of barriers to adherence. This classification schema could then be used in the development of interventions that better meet the needs of HIV-infected youth.
The purpose of this study is to provide long-term clinical safety and efficacy data for tenofovir disoproxil fumarate and emtricitabine in HIV-infected patients experiencing various degrees of renal impairment.
It is not known if anti-HIV treatment for recently infected patients improves long-term patient prognosis. The purpose of this study is to determine if a one year course of anti-HIV medications slows progression of HIV disease in adults recently infected with HIV. Study hypothesis: A one-year course of HAART administered during acute or early seroconversion may slow the progression of HIV infection.
