Filter by:This pilot study focuses on the persistence of central nervous system (CNS) immune activation that has been observed in the presence of 'effective' combination antiretroviral therapy (cART). Attention to this issue is based on the fear that chronic CNS immunoactivation can cause indolent brain injury that will eventually compromise brain function as patients survive for years on treatment. A leading hypothesis explaining this continued immunoactivation is that viral replication continues within the brain at a level too low for detection in cerebrospinal fluid (CSF), yet sufficient to stimulate local immunoactivation. Based on this hypothesis, we propose to use augmented treatment with raltegravir to test whether additional suppression of this hypothesized CNS HIV-1 replication will reduce continued CNS immunoactivation.
In 2005, there were 50,620 HIV-infected children living in Thailand. Current anti-HIV regimens, comprised of individual pills for each drug, frequently lead to missed doses. To properly control their infection, regimens that are tolerable and effective in children and without pill burden are necessary. The primary purpose of this study is to evaluate the safety and bioavailability of GPO-VIR Z30, a combination fixed dose tablet containing zidovudine (ZDV), lamivudine (3TC), and nevirapine (NVP), in HIV-infected children in Thailand.
The purpose of this study is to examine the ability of AGS-004 to control HIV-1 replication and to determine if HIV-1 immunotherapy made with dendritic cells is safe and well tolerated, to determine if immunotherapy increases the body's immune response to HIV-1; and, to determine if after stopping anti-HIV drugs, immunotherapy can control the HIV-1 virus.
HIV infected patients exposed to Hepatitis B virus are more susceptible to develop a chronic and severe liver disease, with a major risk of cirrhosis and liver cancer. However, immune response to standard Hepatitis B vaccination is decreased in HIV-infected patients, compared to non HIV-infected individuals, and, in case of response, its durability has to be carefully followed up. This study compares the efficacy of two strategies of revaccination in HIV-infected patients who didn't respond to previous hepatitis B vaccination. Failure is defined by two conditions: non response to the primary immunization (2 to 4 single-dose injections received before the screening visit) and failure to a single 20 µg boost before being included in the study.
This study will evaluate the effectiveness of community-level behavioral and biomedical interventions, each alone and combined, in reducing sexual risk behavior and HIV/sexually transmitted infections in Peruvian men who have sex with men.
Prevention of HIV-1 transmission from mother-to-child by non-breast-feeding is complicated by increased infant mortality in developing countries. However, extensive counselling about formula feeding turned out safe in Vietnam, a middle-income country.Extensive counselling together with formula feeding and antiretroviral therapy reduced vertical transmission of HIV-1 considerably.
This protocol aims to determine the risk/benefits of this policy by comparing head-to-head a regimen of GPO-VIR Z or TDF/FTC/NVP for 18 months in ARV-naïve patients to a 6-month lead in with GPO-VIR S followed by 12 months of GPO-VIR Z. The primary outcomes to be assessed will be anemia, neuropathy, lipoatrophy and renal function.
This is a single arm, longitudinal study to examine the safety, tolerability, and pharmacokinetic and metabolic characteristics of Raltegravir among 40 African-American, HIV-infected, patients.
Late diagnosis of HIV infection is believed to be responsible for high rates of HIV transmission. The purpose of this study is to determine whether targeted screening versus routine screening will identify a greater number of HIV infected participants. This study will also compare the costs of the resources used for targeted screening versus routine screening.
The purpose of this research study is to learn about levels of antiretroviral drug levels and response to HIV virus in the genital tract of women who are post-menopausal. The investigators in this study think that the levels of hormones post-menopausal HIV-infected women may have in their bodies may affect the levels of antiretroviral drug, and therefore affect how much HIV virus they have in their bodies. Since women who have already gone through menopause have different levels of hormones, such as estrogen, than women who are pre-menopausal, the investigators would like to check the levels of antiretroviral drugs in their blood, their genital secretions, and their genital tissue.
