Filter by:The study is being conducted to evaluate whether African potato, an herbal medicine, can be used together with anti-HIV medicines without affecting the amounts of the anti-HIV medicines in the blood. African potato is an African herbal medicine widely used in Africa, particularly sub-Saharan Africa. Although it has not been proven, it is believed to help boost the immune system. Similar studies have been done on herbal medicines especially those that are used in developing countries. In some cases, the herbal treatments can affect the blood levels of other medicines when the medicines are used together. This study will measure the effect of African potato on lopinavir/ritonavir (Kaletra®), a common anti-HIV medicine. Lopinavir/ritonavir is approved by the United States Food and Drug Administration (FDA). The information obtained from this study will tell us if African potato and anti-HIV treatments can be used together to treat HIV infected patients in Africa and other resource poor regions.
HIV-1 infection is characterized by progressive depletion of CD4+ T cells that eventually leads to clinically significant immunodeficiency. A chronic generalized immune activation is now being recognized to be the main driving force for T cell depletion, loss of anti-HIV-1 immunity and disease progression during chronic HIV-1 infection. However, it is still unknown whether reducing immune activation will restore CD4 T cell counts and leading to immune reconstitution in chronic HIV infection. Mesenchymal stem cells (MSC) have been demonstrated to decrease immune responses of the host, and can suppress inflammation in HIV-infected non-responders. Here, the investigators propose a hypothesis that MSC can reduce immune activation which subsequently lead to the restoration of CD4 T-cell counts dependent on dose of transfused MSCs in HIV-infected patients.
Purpose: To see how growing older changes the amount of HIV drugs in the blood of HIV-infected men and women. Many changes happen in the body as it ages that may affect the way drugs are carried in the blood, broken down or removed from the body. This study will look at the amount of drug in the blood and cells of the immune system for patients taking efavirenz, tenofovir and emtricitabine or atazanavir boosted with ritonavir, tenofovir and emtricitabine. Participants: The population will comprise of 56 (6 for intensive PK and 50 for sparse sampling) HIV-infected adults currently adhering to an antiretroviral regimen containing efavirenz with tenofovir and emtricitabine and the same number and distribution of HIV-infected adults currently adhering to an antiretroviral regimen containing atazanavir boosted with ritonavir with tenofovir and emtricitabine. Procedures (methods): This study will be completed at the University of North Carolina at Chapel Hill. There will be four groups of subjects: Efavirenz/tenofovir/emtricitabine Group A, Efavirenz/tenofovir/emtricitabine Group B, Atazanavir/ritonavir/tenofovir/emtricitabine Group A, and Atazanavir/ritonavir/tenofovir/emtricitabine Group B. The initial six subjects (Group A) for intensive PK analysis for each regimen will be recruited from the the UNC ID Clinic or the Moses Cone Health System Infectious Diseases Clinic, and will be comprised of non-frail subjects not currently receiving interacting drugs. If subjects provide informed consent, timed blood samples will be obtained to determine pharmacokinetic parameters around an observed dose of one of the two study regimens. A whole blood sample will also be collected and stored for potential drug metabolizing enzymes and transporters genotyping in the future. Group A subjects will complete a follow-up visit after their sampling visit. 50 subsequent subjects (Group B) for each regimen will be screened simultaneously, with no more than 10 subjects enrolled for each regimen in Group B prior to the completion and analysis of Group A. These subjects will also be recruited from either site. Group B subjects will have one or two sampling visits with 1 to 4 blood samples obtained at each visit, with a stored sample for future genotyping obtained on one of the visits. Samples will be collected just prior to a dose, at 2 hours, between 4 and 6 hrs, and between 10 and 14 hours after a medication dose. These visits may coincide with the subjects' regularly scheduled visit to the clinic, or be scheduled separately, depending on the preference and availability of the subject.
This study will draw from proven interventions to refine and pilot test a cue card driven computer-assisted intervention, along with HIV/STI testing, that will be tailored to each participant's demographic characteristics, risk behaviors, and biological test results. The specific aims of the proposed study are: 1. To refine a cue card driven computer-assisted risk reduction intervention that will be tailored to each participant's demographic characteristics (e.g., gender, ethnicity), risk behaviors, and biological test results (HIV, hepatitis B and C, syphilis and herpes). 2. To pilot test the tailored intervention's effects on sexual risk behaviors (e.g., frequency of unprotected sex, condom use), drug use during sex and injection risk behaviors (e.g., direct syringe sharing, indirect sharing practices) using a two-group randomized design that compares the tailored intervention with a delayed treatment control condition. 3. To assess the feasibility and acceptability of the tailored intervention in a rural setting.
The objective of this study is to observe and collect data on the usage, dosing, tolerability, and effectiveness of Kaletra (lopinavir/ritonavir) tablets in human immunodeficiency virus (HIV)-infected patients. In some patients, the study is to show the impact on tolerability of changing therapy to Kaletra tablets from other regimens.
Long term observation of patients under lopinavir/ritonavir containing therapy
This is a randomized controlled trial of injectable intramuscular naltrexone (XR-NTX) versus intramuscular placebo among HIV-infected prisoners meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for alcohol dependence or problem drinking, who are transitioning to the community and seeking treatment to prevent relapse to alcohol use. We hypothesize that extended release naltrexone (XR-NTX) will result in improved HIV outcomes (lower log10 HIV-1RNA levels and higher CD4 count) as well as improved alcohol treatment outcomes, and reduced drug/sex HIV related risk behaviors and decreased rates of reincarceration.
This non-interventional, post-marketing observational study was conducted to obtain safety data from the use of lopinavir/ritonavir (Kaletra), in clinical practice, in pregnant women and their children in Japan.
This non-interventional, post-marketing observational study was conducted to obtain data, such as safety and effectiveness, from the use of lopinavir/ritonavir (Kaletra) in clinical practice and investigate the necessity to conduct a follow-up post-marketing clinical study in Japan.
The purpose of this study is to investigate the tolerability of Kaletra (lopinavir/ritonavir) in combination with new substances such as integrase inhibitors (INIs), C-C chemokine receptor type 5 (CCR5) antagonists, and new non-nucleoside reverse transcriptase inhibitors (NNRTIs), as there are many reasons (intolerability, complex resistant patterns or even personal reasons) which may result in a change from the daily clinical routine and lead to the use of a newly approved antiretroviral agent in combination with Kaletra.
