Filter by:Kaletra (a combination drug with lopinavir and ritonavir) is one of a few effective medications that are approved and available for young children who are HIV+. The liquid form is reported to have a very nasty taste and presents difficulties for the children who must take the medication twice a day and for their parents who must enforce the medication regimen. The children are often well into their teens before they weigh enough to be able to take the adult dose tablet (200mg/50mg). A new smaller dose tablet (100mg/25mg) is now available. However, it is not known if the liquid and tablet act the same in children. The purpose of this study is to switch children from the baseline treatment with the liquid to the study intervention treatment with 100mg/25mg tablet form of Kaletra. The study will compare children pre-switch and post-switch in terms of how well their HIV is controlled . Comparisons of parent and child satisfaction will also be made. Eight to 10 HIV+ children currently well managed with a medications including liquid Kaletra will be invited to switch from the liquid to the low dose Kaletra tablet. The parent and/or child will complete a satisfaction survey for the liquid Kaletra and lab values will be taken from the chart. At the time of the switch and 1, 3 and 6 months post switch blood tests will be drawn and the parent and/or child will complete the satisfaction survey. In addition, at the switch and 1 month post switch, a day will be spent in clinic with 5 blood draws to see how much of the drug is in the blood stream at different times after the medicine is taken.
This study is an open-label, randomized, pilot comparison of the effects of either lopinavir/ritonavir or efavirenz in combination with tenofovir plus emtricitabine on cholesterol metabolism, mitochondrial functioning and immune response in 50 naive HIV patients after 48 weeks.
Influenza vaccination has proved it's effectiveness over many years of usage including HIV/AIDS patients who are immunocompromised. In those patients, however, a noted rise in HIV viral load which follows intramuscular injection of the vaccine is of unknown significance over the long run. Mesotherapy is a procedure developed and practiced in france by which a reduced and diluted amounts of antigens is being introduced by multiple intradermal injections over the torso and upper back. Mesotherapy is mainly used as a vehicle for introducing pain medicine and cosmetics.
Vaccination of HIV infected individuals with the sub-unit influenza vaccine is safe; however it induces only moderate immune responses and likewise is modest in its protection compared to HIV uninfected individuals. Based upon the available data, the South African Thoracic Society has provisionally recommended the use of influenza vaccine in HIV infected individuals with CD4+ counts of > 200/ml and viral loads of < 100 000 copies/ml.(Green R et al. In press, SAMJ). This proposal is however based upon recommendations made elsewhere with minimal level of evidence regarding its benefit, and no evidence from countries with a high prevalence of HIV. Very few HIV infected adults, however, actually do receive influenza vaccine in South Africa, partly because of the absence of compelling data regarding the burden of disease in Africa as well as lack of vaccine effectiveness and issues related to physician awareness and access to influenza vaccine in the public immunization program. The conflicting evidence, between developed countries and Africa, regarding the effectiveness of PPV highlight the drawbacks of extrapolating vaccine effectiveness data from developed countries to developing countries. Differences in the epidemiology of HIV between developed countries in which the prevalence of HIV is low to that of high-burden sub-Saharan African countries include: - differences in the mode of transmission of HIV and demographics of the infected population. - differences in standard of care, including access to prophylaxis against opportunistic infections and use of highly active anti-retroviral therapy (HAART) - differences in risk for disease from opportunistic pathogens, e.g. Mycobacterium tuberculosis, etc. These differences may all contribute to differences in the risk and severity of influenza illness among HIV infected adults from these communities as well as possibly responsiveness and effectiveness of vaccination. The investigators are conducting a double-blinded, placebo controlled randomized trial at the HIV treatment clinic at Helen Joseph Hospital to determine the effectiveness of influenza vaccination in HIV infected adults in South Africa. The significance of the findings from this study will help quantify the burden of influenza illness in African HIV infected adults, as well as assist in making more informed recommendations for the use of influenza vaccine in HIV infected adults and in guiding national policy for preparing for a future influenza virus-pandemic.
A randomized clinical trial evaluating the reduction of HIV risk behaviors and drug use when providing integrated behavioral drug and HIV risk reduction counseling (BDRC) along with methadone maintenance treatment in Wuhan, China
The purpose of this study is to test the safety of an investigational medication, TXA127, and its ability to increase T-lymphocyte counts, specifically CD4+ T-lymphocytes, in persons infected with human immunodeficiency virus who are taking highly active anti-retroviral therapy.
For participants with HIV taking either lopinavir or fosamprenavir who have elevated triglycerides, this trial will study the change in triglycerides after switching protease inhibitors.
In this study, the investigators will assess the population effectiveness of using routine HAART as a PMTCT strategy, through a community-based survey. The survey will be done in the catchment areas of four health clinics in rural Zambia both before and after giving routine ART in the clinics, so as to estimate population HIV-free survival among infants born in each target community. The investigators hypothesize that incorporation of routine ART into PMTCT will increase the HIV-free survival of exposed infants to 75%.
The investigators will enroll a cohort of HIV-infected pregnant women accessing PMTCT services, to better understand the incremental benefits (e.g. reduction in HIV transmission, improvements in HIV-free survival) and risks (e.g. drug toxicities) of the routine HAART strategy, in comparison to HIV-infected pregnant women accessing the Zambian Standard of Care services. The investigators will test the hypothesis that routine use of HAART produces significant reductions in HIV transmission rates, with only minimal side effects.
CCTG 589 is a randomized, open-label, pilot study comparing the efficacy, safety and tolerability of RAL plus LPV/r to EFV plus TDF/FTC in HIV-infected, treatment-naïve subjects. Subjects will be ineligible if they have any evidence of drug resistant virus in the past or at the time of screening (if never previously tested). Those who are found to be eligible will be randomized 1:1 to initiate either LPV/r (400/100 mg) plus RAL (400mg), both given twice-daily, or fixed dose combination of EFV (600 mg), TDF (300 mg) and FTC (200 mg) given as once-daily Atripla® for 48 weeks. Hypotheses 1. The novel nucleoside-sparing combination of LPV/r + RAL will have a faster phase 1 viral decay rate compared to standard-of-care therapy with EFV/TDF/FTC in antiretroviral-naïve patients. 1. Faster phase 1 viral decay dynamics will be associated with improved longer-term (week 48) viral suppression. 2. Faster phase 1 viral decay dynamics will be associated with accelerated early (Day 0-14) clearance of cell-associated HIV DNA. 3. Faster phase 1 viral decay dynamics will be associated with greater early (baseline to week 12) CD4+ T-cell recovery. 2. The LPV/r + RAL arm will have greater decreases in early (baseline to week 4) CD4/CD8 T-cell immune activation and apoptosis which will be associated with greater late (week 12 to week 48) CD4+ T-cell recovery. 3. Subjects treated with LPV/r + RAL arm will have smaller changes in total cholesterol and triglycerides from baseline than those receiving EFV/TDF/FTC.
