Filter by:In 1999, when initiating antiretroviral treatment in HIV infected adults, a triple combination with protease inhibitor is recommended. Such therapy induces side effects and the number of pills may reduce therapy adherence. The aim of this study is to evaluate the efficacy and the safety of a once daily FTC, ddI, efavirenz combination, in HIV patients with CD4 cell count over 100/mm3, antiretroviral naive.
The purpose of this pilot study is to evaluate efficacy and safety of addition of IL-2 to pegylated interferon alpha 2a and ribavirin in HIV-HCV coinfected patients non-responders after three months of standard therapy with pegylated interferon alpha 2a and ribavirin. IL-2 may enhance numbers and function of CD4 T lymphocytes and specific anti-HCV immune responses and could participate to the control of HCV replication
The main purpose of this study is to learn whether the study vaccine and the adjuvants(drugs that are used to help immune response) have an acceptable safety profile in treating individuals with HIV. A second purpose for this study is to understand how your immune system responds to the study vaccine with the adjuvants. Understanding these differences could be useful in several ways. First, it might help identify people whose disease is likely to respond to the study vaccine with the study adjuvants. Second, the information might be useful in developing other treatments for people whose disease does not respond to the study vaccine with the adjuvants.
The purpose of this study is to learn whether the study vaccine and adjuvants (drugs that are used to help improve immune responses) have an acceptable safety profile in treating individuals with HIV. A second purpose of this study is to understand how the immune system responds to the study vaccine and adjuvants.
This study is designed to test two separate strategies for treatment of anemia (low hemoglobin) and neutropenia (low white blood cells) in HIV/HCV coinfected patients who are being treated with pegylated interferon and ribavirin.
Following significant reduction in antiretroviral drug prices over the past two years, more HIV-1 infected African adults and children are gaining access to treatment. However, due to complex drug regimens that have to be taken continuously, suboptimal adherence is likely to be a formidable challenge. As programs providing antiretroviral drugs in Africa scale up, achievement of excellent adherence is a high priority as this will result in maximum benefits from the drugs and forestall development of resistant virus. A better understanding of predictors of pediatric HAART adherence in African children is essential in order to formulate feasible, culturally appropriate, strategies to monitor and enhance adherence. There is also urgent need to evaluate simple, inexpensive interventions that are widely applicable in the African setting. The medication diary has been used empirically among HIV infected adults and children in Western countries, mainly as a tool for monitoring and to a lesser extent improving HAART adherence. Literacy levels have risen significantly in most African regions over the past few years, and the diary can also be further modified using pictures to suit parents of different literacy levels. We propose to conduct a randomized control trial to determine the effect of medication diaries and counseling versus counseling alone on HAART-adherence in HIV-1 infected children and their parents/caregivers in Nairobi Kenya.
The University of Washington has received funding to conduct a proof-of-concept trial to assess the impact of suppression of genital herpes on HIV infectiousness. This study (the Partners in Prevention Study) will enroll HIV discordant heterosexual couples in which the HIV-infected partner is co-infected with herpes simplex virus type 2 (HSV-2) to test the efficacy of twice daily (bid) acyclovir (400 mg) given to the HIV-infected partner to prevent transmission to his/her HIV negative partner(s). This randomized, double-blind, placebo-controlled proof-of-concept trial will provide evidence for the efficacy of HSV-2 suppression with daily acyclovir on HIV transmission among HIV-discordant couples among whom the HIV-positive partner is also HSV-2 seropositive with CD4 >250. The researchers hypothesis is that, by decreasing the frequency and amount of genital HIV shedding, standard doses of daily acyclovir 400 mg bid will reduce the rate of HIV transmission by 50% in HIV-discordant couples among whom the HIV-infected partner is HSV-2 positive. Under the study protocol version 4.1.1, 3000 HIV-discordant heterosexual couples in which the HIV-positive partner is HSV-2 positive and has a CD4 count >250 will be recruited; participants will be followed for up to 2 years. A 4% per year HIV incidence in the placebo arm is assumed. The first study site began enrolling participants on 17 November 2005. As of September 2006, 14 sites in Eastern and Southern Africa had participated in recruiting the 2300 HIV-discordant couples enrolled to date.
Combination antiretroviral therapy for the treatment of HIV has a high pill burden. Two dual-tablets, abacavir-lamivudine and tenofovir-emtricitabine, are now licensed in the United States and will be available in Australia in December 2005. Data available suggest that the potency of these tablets are similar in controlling replication of the HIV virus, but not have not been directly compared in regard to clinically significant toxicities. We therefore aim to compare the overall safety and efficacy of the two dual-tablets over a 2 year period in HIV infected adults. We hypothesise that the two dual-NRTI treatments will be similar in efficacy and safety.
This is a randomised study of the effect of treatment with Combivir (zidovudine [AZT] and lamivudine [3TC]) and Kaletra (lopinavir [LPVr]), alone and in combination, on the development of abnormalities in lipid and glucose metabolism in HIV negative healthy subjects.
Saquinavir and Atazanavir are drugs used in combination therapy to treat HIV disease. Saquinavir is currently available in a 200 milligram capsule. Most individuals currently on saquinavir require to take 5 tablets twice a day. In an attempt to reduce this number of pills, a new capsule has been developed containing 500 milligrams of saquinavir. This study will assess: i) blood drug levels in individuals taking both saquinavir formulations, ii) blood drug levels in individuals taking both saquinavir formulations when given with atazanavir, iii) 48 weeks of follow up for individuals receiving the new saquinavir formulation with atazanavir as HIV therapy.
