Filter by:The use of anti-HIV drugs following a potential sexual or injecting drug use exposure to HIV in order to try and prevent an exposure from becoming an infection is common. This is called nonoccupational postexposure prophylaxis (NPEP). The likelihood of NPEP succeeding is related to intrinsic qualities of the drugs used which includes at which point in the life cycle of the HIV virus the drugs work, how strong the drugs are against HIV, and how well tolerated the drugs are i.e. what side effects they produce. Many people skip doses during their treatment or abandon their treatment because of side effects. The anti-HIV drug raltegravir works early in the life cycle of the virus i.e. before it integrates with human DNA, is potent against HIV and causes few side effects. These qualities make it an obvious choice for use as a NPEP treatment. In this study 100 HIV negative men will receive raltegravir along with another HIV drug called truvada (commonly used in NPEP) for 28 days after a possible sexual exposure to HIV. They will be monitored closely for adverse events, side effects and for their ability to take the medicine each day for the whole 28 days. The hypothesis in this study states that raltegravir use in NPEP will be safe, well tolerated and result in a high treatment completion rate.
We are studying if putting a gel capsule over a standard HIV drug changes the ability of the body to absorb the drug. This is important because we want to be able to study new HIV drugs against the most common drugs used today and the most common is Sustiva, which is also called efavirenz. We will give you Sustiva every day for 5 days and draw blood to see how much is absorbed. Then we will give you Sustiva that has a gel capsule over it for 5 days and we will draw blood to see how much is absorbed.
The purpose of this study is to determine if prophylactic cotrimoxazole makes severe anemia or neutropenia more common in infants exposed to maternal HIV and combination antiretroviral therapy.
Validate a simple and cost-effective Nucleic Acid Test for HIV Detection in order to develop a rapid, highly sensitive and specific, one-stage test for the diagnosis of HIV infection. Blood samples collected will be assayed using the BioHelix Corporation helicase-dependent amplification or the Cepheid Xpert HIV-1 Quant Assay. A false negative or false positive rate of >1.0% would make this test unacceptable as a screening test for HIV viremia.
The broad objective of this project is to test the efficacy of a theory-based HIV risk-reduction intervention, which includes both an adolescent component and parental component, designed to reduce the adolescents' risk of sexually transmitted HIV.
Long term observation of patients under lopinavir/ritonavir containing therapy
DNA vaccines consist of small pieces of DNA also known as plasmids, and have several potential advantages over traditional vaccines. Thus far, DNA vaccines appear to be well tolerated in humans. We have developed DNA vaccine, PENNVAX-B, which includes plasmids targeting the gag, pol, and env proteins of HIV-1. The vaccine will be delivered via electroporation (EP) which uses the CELLECTRA constant current device to deliver a small electric charge following injection, since animal studies have shown that this delivery method increases the immune response to vaccine. The vaccine will be given to HIV-1 infected subjects whose viral load is undetectable on a HAART regimen, with CD4 lymphocyte count above 400 cells/µL of blood. It is hypothesized that PENNVAX-B + EP will be safe and well tolerated.
In Serono Study 24380, the antecedent protocol to Study 25373, patients were randomly assigned in a 3.0-to-1.0 ratio to Groups A and B. All patients in Group A received recombinant human growth hormone (Serostim®) 4 mg daily (the "induction" phase) for the first 12 weeks, and then were re-randomized to receive either placebo or Serostim 2 mg on alternate days (roughly equivalent to 1 mg daily) during Weeks 12-36 (the "maintenance" phase). All patients in Group B initially received placebo from baseline to Week 24, and then received Serostim® 4 mg daily from Weeks 24 to 36 (Grunfeld, 2007). In the follow-up Study 25373, any subject who was enrolled in Serono Study 24380 and was assigned to Group A, who fully completed all study visits without a major protocol violation, was eligible to enroll to receive re-treatment with Serostim at a dose of 4 mg daily for 12 weeks. During study 25373, safety was monitored by recording of adverse events and measurement of urinalysis and laboratory blood tests to assess fasting glucose, fasting insulin, and routine biochemistry and hematology parameters. At Week 12 or at the time of study termination, subjects underwent re-assessment of body composition via anthropometry measurements and dual photon absorptiometry (DXA) scanning. In addition, at study termination, measurements of insulin-like growth factor I (IGF-I), insulin-like growth binding protein 3 (IGFBP-3), fasting lipid profile, and oral glucose tolerance testing were obtained.
Combined antiretroviral therapy (cART) is associated with facial lipoatrophy, which is potentially stigmatizing for HIV-positive patients. Eutrophill is a 2.5% polyacrylamide hydrogel obtained by polymerization of acrylamide monomers with an official half-life of 5 years. Preliminary encouraging results with the use of polyacrylamide hydrogel for reconstruction of facial lipoatrophy in HIV-infected patients have been previously reported. The primary objective of the study was to evaluate the long-term efficacy and safety of subcutaneous facial injections of Eutrophill in HIV-infected patients with severe facial lipoatrophy as assessed by facial ultrasonography at screening , after 6, 12 and 24 months
Twice daily fosamprenavir, in combination with low dose ritonavir (FPV/RTV BID), is indicated for the treatment of HIV-infected adults, adolescents and children of 6 years of age and above for use in combination with other anti-HIV medicines. Safety data from two GlaxoSmithKline (GSK) clinical trials (APV29005 - involving twice-daily doses of FPV with or without RTV and APV20003 - with once daily dosing of FPV/RTV among 2-18 year olds) indicated that gastrointestinal events were the most commonly reported AEs, but that the majority of events were mild and of short duration. Treatment emergent grade 3 / 4 neutropenia was reported in 20% of children in the APV20003 trial; and neutropenia was identified as a potential safety concern by the European Medicines Agency (EMEA). The objectives of this study were to conduct an observational cohort study of the usage and safety of FPV/RTV in children and adolescents (aged 6 ≤ 18 years) with HIV infection in several European HIV paediatric cohorts. Data will be collected for 3 years (2008, 2009 and 2010).
