Filter by:In this study, we will determine whether treating pregnant and breastfeeding women co-infected with human immunodeficiency virus type 1 (HIV-1) and herpes simplex virus type 2 (HSV-2) with daily valacyclovir will reduce HIV-1 levels in plasma, genital, and breast milk and will decrease the risk of mother-to-child HIV-1 transmission (MTCT).
This study will examine the effectiveness of Mindfulness-Based Stress Reduction (MBSR) in helping men living with HIV cope with negative emotions and stresses in their life. MBSR is an approach to reducing stress for patients with chronic medical conditions. It involves systematic training in mindfulness meditation practices to increase quality of life and to reduce general stress, anxiety, depression or pain. The effectiveness of MBSR will be evaluated by looking at changes in participants' experience of stress, anxiety associated with pain management and psychosocial functioning before and after they receive the MBSR compared with participants who do not receive the MBSR treatment. In order to participate, individuals must be: male, living with HIV, age 18-70 years, live within one hour of participating centre, and have a good understanding of the English language. Questionnaires will be completed before individuals begin the program, at the end of the intensive phase (8 weeks) and at 6 months after the start of the group program. The primary program evaluation outcome will be a reduction in stress; secondary evaluation outcomes will include the improvements in the physical and emotional experience of pain as well as general psychosocial functioning and self-esteem.
This Phase I study is directed at evaluating the safety profile (as a primary end-point) and the immunogenicity (as a secondary end-point) of the recombinant HIV-1 Tat vaccine in healthy, immunologically competent adult subjects without identifiable risk of HIV-1 infection.
The primary objective of this study is: To assess the virologic effect of changing enfuvirtide to MK-0518(raltegravir) in human immunodeficiency virus type 1(HIV-1) infected patients who have an undetectable level of serum human immunodeficiency virus(HIV) (< 75 copies/ml by branch deoxyribonucleic acid (bDNA) assay, < 50 copies/ml by Ultrasensitive Polymerase Chain Reaction(PCR) assay) on their current HIV medication regimen. Hypothesis: HIV-1 infected individuals well controlled on an enfuvirtide containing regimen with HIV RNA levels below limits of quantification can safely have the investigational integrase inhibitor, MK-0518 substituted for enfuvirtide without loss of virologic suppression.
The primary objective of this study is to assess the efficacy of switching to tenofovir disoproxil fumarate (TDF) compared to continuing stavudine or zidovudine in maintaining virologic suppression in HIV-1 infected children.
The investigators hypothesis is that switching from a ritonavir-boosted PI to raltegravir may be associated with an at least non-inferior effectiveness, virological response and safety, and even a better tolerability profile with regard to lipid metabolism, insulin resistance, body fat distribution as compared with continuation of the baseline regimen in HIV-1 seropositive males or females at least 18 years of age and older on ritonavir-boosted PI plus at least 2 other drugs and plasma viral RNA below 50 copies/mL.
The purpose of this study is to evaluate the effect of epoetin alfa on HIV-associated neuropathy by measuring changes in nerve fiber density and pain ratings.
The purpose of this study is to determine the safety, tolerability, and immune response to the DNA HIV vaccine, PENNVAX-B alone, in combination with IL-12, or with 2 different doses of IL-15.
the trial assessed the pharmacokinetics and long term plasma exposure of the following antiretrovirals: atazanavir when combined to ritonavir and the tenofovir/emtricitabine fixed-dose combination. All drugs will be delivered in MEMS electronic device to monitor dosing history.
This is a prospective cohort study where HIV-infected and uninfected children will be enrolled between 6 weeks and 9 months of age and followed to the age of 21 months. All HIV-infected children will be given trimethoprim-sulfamethoxazole (TMP-SMX) prophylaxis as of 6 weeks of age. HIV-uninfected children born to HIV-infected mothers will be given TMP/SMX prophylaxis for the duration of breastfeeding and then randomized to the continuation of TMP/SMX or discontinuation of TMP/SMX prophylaxis. HIV-uninfected children born to HIV-uninfected mothers will not be given TMP/SMX prophylaxis. Study participants will be followed for all of their health care needs in a designated study clinic. All mother-child pairs will receive a basic care package including insecticide-treated bednets (ITNs) at enrollment. All HIV-infected mothers and children will receive antiretroviral therapy if eligible according to standardized World Health Organization (WHO) criteria. Study participants 4 months of age or older and at least 5 kg will be randomized to treatment with artemether-lumefantrine (AL) or dihydroartemisinin-piperaquine (DP) at the time of their first diagnosis of uncomplicated malaria. Study participants will receive the same antimalarial treatment regimen for all future episodes of uncomplicated malaria. Study participants less than 4 months of age or less than 5 kg diagnosed with malaria and all episodes of complicated malaria will be treated with quinine in accordance with local guidelines. The investigators will test the hypotheses that: 1. TMP/SMX prophylaxis is highly effective in preventing malaria in both HIV-infected and HIV-uninfected children 2. The use of TMP/SMX prophylaxis is associated with an increased risk of infection with malaria parasites containing antifolate resistance-conferring mutations. 3. The use of antiretroviral (ARV) drugs is associated with a decreased incidence of malaria. 4. The efficacy, safety, and tolerability of AL and DP for the treatment of uncomplicated malaria differ. In 2008, we received approval and funding to extend the trial until 2012. We are now following all children through 5 years of age. First randomization to continue or discontinue TMP/SMX prophylaxis in our HIV-exposed population occurs 6-8 weeks after cessation of breastfeeding when HIV status can be confirmed as negative by DNA PCR. A second randomization occurs at 2 years of age in our HIV-exposed participants. At that point all HIV-exposed children who were originally randomized to continue TMP/SMX prophylaxis are again randomized to either immediately discontinue TMP/SMX prophylaxis or continue prophylaxis until age 4 years. All children will be off TMP/SMX between 4 and 5 years of age. We have also added an additional hypothesis to test during the study extension: 5. Prolonged TMP/SMX prophylaxis will result in an increased incidence of malaria in children in the year immediately following cessation of prophylaxis compared to children who have not used prophylaxis for over a year and those who have never been on prophylaxis.
