Filter by:The purpose of this study is to see if vitamin B can treat mild hyperlactatemia (a higher than normal level of lactate in the blood) in patients who take nucleoside reverse transcriptase inhibitors (NRTIs). Hyperlactatemia is a potentially life-threatening condition that can be associated with NRTI therapy. A lack of vitamin B may be related to the development of hyperlactatemia. However, no studies have been done to evaluate this. This study proposes that high doses of vitamin B may bring elevated lactate levels back to normal among patients taking NRTIs.
Even though powerful anti-HIV drug combinations have been successful in patients with little or no prior anti-HIV therapy, studies have shown that these treatments are less effective in patients who have been treated with nucleoside analogues. This study will test the safety and effectiveness of adding one or two new drugs to a personalized anti-HIV regimen for patients whose previous HIV treatments have failed.
Despite risk reduction counseling, some individuals in HIV vaccine trials or vaccine preparedness studies may engage in risk behavior that results in HIV infection. The purpose of the HVTN 403 study is to find out more about how persons respond to HIV infection if they have received an experimental HIV-1 vaccine before they became HIV infected. Some people in HVTN 403 received an experimental HIV vaccine as a participant in a clinical trial before getting infected with HIV. Other people in this study were in a vaccine preparedness study when they got infected with HIV. None of these individuals became infected with HIV as result of their participation in an HIV vaccine or vaccine preparedness study. HVTN 403 will compare immune responses between those who previously received an experimental HIV vaccine and those who did not. Information learned from this study may be important in guiding future developments of new HIV vaccines and other treatments for HIV and AIDS.
The purpose of this study is to determine the ability of HVTN sites to recruit and retain people at risk for HIV infection for possible future HIV vaccine research studies. This study also aims to learn more about the risk behaviors of people at high risk for HIV infection. In order for studies to be successful, study sites must be able to recruit, enroll, retain, and inform groups at high risk for HIV infection. The plan for Phase III HIV vaccine trials will depend on the number of participants enrolled, the rate at which participants become HIV-infected, the length of follow-up, and the number of participants who continue and follow through with the entire study. At existing sites, it is necessary to evaluate the potential to recruit new groups. At possible expansion sites, work is necessary to establish effective procedures to recruit and retain participants and to identify HIV incidence rates. This study will accomplish those goals.
To conduct a prospective study of pediatric transfusion recipients to determine the risk of transmitting various infectious agents by blood transfusion.
The purpose of this study is to find out if anti-HIV drugs can be stopped without the virus becoming resistant to the drugs. The study will also examine how fast anti-HIV drugs leave the body. Not all HIV-infected patients may require continuous and indefinite anti-HIV therapy. There is evidence that stopping anti-HIV therapy will not make the virus resistant to efavirenz (EFV), an anti-HIV drug that remains in the body longer than most treatment drugs. In another study, patients were treated with EFV, zidovudine (ZDV), and lamivudine (3TC). The patients' virus was controlled despite the fact that some patients missed medication dosages. Many patients stop anti-HIV therapy because of negative effects. This study will examine the body's ability to fight and control virus in patients who stop therapy.
The overall purpose of the proposed study is to determine whether three short-term stress management interventions along with booster strategies will improve and sustain improvements in psychosocial functioning, quality of life, and somatic health among persons with varying stages of HIV disease. The 10-week group interventions are designed to reduce perceived stress and increase coping effectiveness and include cognitive-behavioral stress management focused on positively living (+LIVE), focused Tai Chi (TCHI) training, and spiritual growth groups (SPRT). Effects of the interventions will be evaluated immediately upon completion of the group training and at 6 months and 12 months following stress management training.
Ritonavir (RTV) is a protease inhibitor (PI) commonly used to increase drug levels of other PIs in HIV drug treatment. The purpose of this study is to compare a combination of drugs which includes RTV and 2 protease inhibitors (PIs) with 2 combinations that include RTV and another PI. This study also will compare the effectiveness, safety, tolerability, and drug levels in the blood of these anti-HIV drug combinations.
Many HIV infected patients admitted to the intensive care area (ICA) have never taken anti-HIV drugs. The purpose of this study is to learn whether starting anti-HIV drugs while patients are in an ICA will help them to survive and get better faster. This study will also evaluate patients who, though not in an ICA, have been admitted to the hospital for serious illnesses or infections.
The goals of this study are to find out if fat wasting and weight loss in the arms and legs of HIV patients taking highly active antiretroviral therapy (HAART) are caused by nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) and if wasting can be reversed if the NRTI is stopped and replaced with other anti-HIV drugs.
