Active clinical trials for "HIV Infections"

The investigators propose to develop and evaluate a computer-based intervention using cell phones to enhance adherence to antiretroviral treatment (ART) and support of HIV transmission risk-reduction among adult HIV-positive patients in Peru.

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 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.

The specific aims of this study are to determine whether HIV-infected patients with significant fat redistribution and ectopic fat accumulation have increased brown adipose tissue using 18F-FDG Positron Emission Tomography techniques. Recent studies suggest down regulation of Dicer, a major component of miRNA has an important role in the differentiation and function of brown and white adipose tissue and may contribute to lipodystrophy. Therefore we will expand on recent research in this area by recruiting HIV-infected men with lipodystrophy. We will perform subcutaneous fat biopsies of the dorsocervical and abdominal fat in a subset of HIV-infected and non-HIV-infected men in order to explore further the question of down regulation of Dicer and its implication on metabolic abnormalities in this population.

Infections with HIV-1 group O are found in 1 to 3 % of persons living with HIV in Cameroon. The natural history and treatment response is not well understood. The natural resistance to non nucleoside reverse transcriptase inhibitors and their possible low sensitivity to protease inhibitors complicate the choice of an adequate treatment options. This observational study is aimed at evaluating the antiretroviral treatment response of HIV-1 group O infected patients in comparison with HIV-1 group M infected patients. The proposed standardized follow-up will facilitate a better understanding of the natural history and treatment specificities to improve the patients management. This is a non randomized study, open label, with standardized follow-up. A total of 171 patients

The purpose of this study is to establish normal values for neuropsychological testing in HIV negative Thais stratified by age (1 decade) and education (no certificate or primary school certificate, less than high school certificate or vocational certificate, high school certificate or higher vocational certificate or diploma, Bachelor degree or higher.

The purpose of this study is to find out if antiretroviral drugs are safe and well tolerated by HIV-positive pregnant women and their infants in South Africa and Zambia.

APV10017 was a pharmacokinetic study that evaluated the pharmacokinetics, safety and tolerability of fosamprenavir/ritonavir (FPV/RTV) at reduced doses over 14 days in HIV-infected subjects with mild to moderate hepatic impairment (HI). Based on these data, two new regimens have recently been approved by the EMEA and FDA in these patient groups; FPV 700mg BID/RTV 100mg QD for those with mild HI (Child-Pugh score 4-6) and FPV 450mg BID/RTV 100mg QD for those with moderate HI (Child Pugh score 7-9). The Committee for Medicinal Products for Human Use (CHMP) has requested longer-term safety data among this hepatically impaired HIV-infected population who have received the recently updated FPV/RTV dosing regimens. An observational cohort study will be conducted using routinely collected data in three European HIV patient cohorts with a high proportion of hepatitis co-infected individuals. Patients who received FPV/RTV will be followed to address the following objectives. Primary: To assess the safety and tolerability of FPV/RTV-based ART in subjects with mild to moderate hepatic impairment. Secondary: A). To compare the safety and tolerability of FPV/RTV-based ART in subjects with mild to moderate hepatic impairment when compared to FPV/RTV-based ART in hepatitis B (HBV) or hepatitis C (HCV) co-infected subjects with normal hepatic function. B). To compare the safety and tolerability of FPV/RTV-based ART to lopinavir/ritonavir LPV/RTV-based ART in subjects with mild to moderate hepatic impairment.

The purpose of this research is to determine the effectiveness of the novel H1Nl influenza (inactivated/killed formulation) vaccine among both HIV-infected and HIV-uninfected persons. The administration of the H1Nl vaccination is not part of the study's procedures, but is being given as part of routine care.

To reassess nutritional status of HIV-infected Thai children living in the family style community after receiving nutrition support program for 6 months.
