Filter by:This study was designed determine whether use of creatine monohydrate, a dietary supplement, can increase skeletal muscle mass and strength and improve the response to progressive resistance exercise training in people with HIV infection.
The objective of this study is to test in a randomized controlled trial the effectiveness of a US secondary HIV prevention program to reduce HIV risk behaviors, STD acquisition, and alcohol consumption among HIV-infected Russians with risky drinking.
The randomized controlled trial is conducted among antiretroviral naive co-infected HIV and tuberculosis patients who receiving rifampicin-based antituberculous regimen fro at least 4 weeks butt not exceed 16 weeks before enrolment. All patients receive the same backbone regimen of stavudine (30 mg/40 mg twice daily)+ lamivudie 150 mg twice daily. They are randomized to receive nevirapine 400 mg/day twice daily vs efavirenz 600 mg/day at bed time. All patients are followed through 144 weeks after initiation of antiviral therapy. The primary objective are to compare the proportion of patient who achieve undetectable plasma HIV-1RNA<50 copies/ml at week 48. The previous reports demonstrated that the standard doses of both nevirapine and efavirenz coulde be used among co-infected HIV and tuberculosis patients who receiving rifampicin even though plasma levels are somewhat reduced by rifampicin. However, there have been not been a randomized control trial to compare these two regimens. Thus, this trial will provide the efficacy data between these two regimens.
The purpose of this study is to determine if blood levels of the hormonal emergency contraceptive agent, Plan B, are altered by concomitant use with the HIV medication, efavirenz.
This study is a cross-sectional observational study to evaluate the prevalence of HLA-B*5701 in the European area and in major European ethnotypes. Any HIV-1 infected patient will be eligible for this study including treatment naïve and experienced patients, as well as patients previously tested for HLA-B*5701. Patients will be approached during a standard clinic visit, and will be consented prior to any study specific procedure. They will be asked to provide a tissue sample (cheek cells and blood sample) which will be used to assess HLA-B*5701 status by local and central laboratories. In selected sites patients may be asked to provide an additional blood sample. This sample will be used to develop and validate different methodologies for assessing HLA-B*5701 status.
In HIV infected patients, individuals exposed to the virus of Hepatitis B are more susceptible to develop a chronic and severe liver disease with a major risk of cirrhosis and liver cancer. However, the existing protocol of vaccination against Hepatitis B is less efficient in HIV-infected patients than in non HIV-infected-patients, and, in case of response, its longevity has to be followed up carefully. This study compares the efficacy of the standard protocol vaccination with GenHevac-B and 2 other protocols, a double-dose of GenHevac-B and a set of intradermal injections of Genhevac-B, in HIV-infected patients with lymphocytes T CD4 level above 200 permm3.
This study is designed to evaluate the safety of MVA85A in asymptomatic volunteers in South Africa who are infected with M.tb, HIV or both. A single vaccination with MVA85A, when administered at a dose of 5 x 107pfu intradermally, is safe and highly immunogenic in mycobacterially naïve individuals, BCG vaccinated individuals and M.tb latently infected individuals. We will use the same vaccination regime in this study. Participants will be defined as being infected with M.tb.if they have a positive Elispot response to ESAT6 or CFP10. Participants will be defined as being infected with HIV.if they have a positive HIV rapid test (Determine®, Abbott Laboratories) followed by a positive HIV ELISA result. Participants will be identified from the general population living in Worcester, Western Cape, South Africa
HIV infection is a growing problem in Israel with over 4000 known patients who are either infected with the virus or have developed AIDS. Patients are usually followed for years until they develop an increase in their viral load (HIV-1 RNA) or their CD4 + cells decline. At this point, patients are usually treated with Highly Active, Anti-Retroviral Therapy (HAART). The mainstay of response to such treatment is the lowering of viral load and increase in CD4+ cells. Food supplements for HIV patients have been given in several studies, with controversial results. A meta-analysis published recently [1] assessed whether micronutrient supplements are effective in reducing morbidity and mortality in adults and children with HIV infection. They recommended supporting the current WHO recommendations to promote and support adequate dietary intake of micronutrients wherever possible. We expect to enroll 140 subjects in this randomized, double blind, placebo controlled study. Seventy subjects will be enrolled in the rice-supplement arm and 70 subjects in the control group, which will receive supplemental, flavored dextrose to their current medical treatment. The treatment duration is 24 weeks with follow-up at 36 weeks from enrollment. The target population is HIV-1 infected individuals who may be either on anti-retroviral therapy or not on therapy. Subjects must be with either CD4+ cells are <500 cells/mm3, or HIV plasma RNA level is > 5000 copies/ml. The primary objective is to demonstrate the efficacy of food supplementation versus a flavored-dextrose supplement with respect to increment of patient CD4+ cell count from baseline at 24 weeks, or virological response defined as lowering of plasma HIV-1 RNA and immunologic response.
This study will test whether two experimental HIV vaccines are safe and whether they cause any side effects in healthy adults. It will examine the body s immune response to the vaccines and monitor the social impact, if any, of being in an HIV vaccine study. The experimental vaccines in this study are the VRC-HIVADV027-00-VP (also called the rAd35-EnvA vaccine) and VRC-HIVADV038-00-VP (also called the rAd5-EnvA vaccine). The vaccines are made using an adenovirus (virus that normally causes respiratory infections and colds) that has been modified to contain DNA that codes for HIV proteins. The vaccines cannot cause HIV or adenoviral infections. Healthy normal volunteers between 18 and 50 years of age may be eligible for this 2-part study. Part 1 includes 15 people. Part 2 includes 20 people. Part 1 participants receive only the rAd35-EnvA vaccine. The first five people enrolled receive the lowest study dose of the vaccine. If this dose is safe, then the next five people enrolled receive a higher dose. If this dose is safe, then the last 5 people enrolled receive the highest study dose. Subjects in Part I have about five clinic visits over 24 weeks. Part II of the study starts after all injections in Part 1 are given. Subjects in Part 2 are randomly assigned to one of two vaccination schedules. One group receives the rAd35-EnvA vaccine first, followed 12 weeks later with the rAd5-EnvA vaccine. The other group receives the vaccines in reverse order; that is, first the rAd5-EnvA vaccine, followed 12 weeks later with the rAd35-EnvA vaccine. In this schedule, the first vaccination primes the immune system and then the immune response is boosted 12 weeks later with a different vaccine. Everyone in study Part 2 receives the rAd35-EnvA vaccine at the middle dose tested in Part 1. Subjects in Part 2 have about eight clinic visits over 36 weeks. All vaccinations are given as injections in the upper arm. At each clinic visit, participants are checked for health changes or problems. They are asked how they are feeling and if they have taken any medications. Urine samples are collected and blood is drawn at some visits. They are tested for HIV several times and asked questions about their sexual behavior and drug use. Throughout the study, participants are counseled on HIV risk reduction. Subjects are asked about any social effects they may have experienced from their participation in this study.
The HIV epidemic in China has reached a phase of exponential growth; the number of new infections has been steadily increasing over the past decade. The purpose of this study is to evaluate the effectiveness of a Combined Individual- and Community-Based Behavioral Intervention to Improve Quality of Life for HIV-Positive Villagers and decrease HIV related stigma in Rural China.
