Filter by:The SUN Study is a Centers for Disease Control and Prevention (CDC)-sponsored multi-site prospective observational cohort study designed to better understand the incidence and etiology of metabolic and other complications related to effective HIV treatment and longer survival. The SUN Study is also providing a platform to evaluate a behavioral intervention designed to reduce HIV transmission through prevention counseling in routine care.
The purpose of the study is to demonstrate that a regimen using highly active antiretroviral therapy (HAART) to maximally suppress maternal viral load in the late antenatal period and during the first six months of lactation is safe, effective and can be implemented in resource poor settings in order to reduce the risk of HIV transmission to the infant.
The objective of this study is to determine the long term safety and tolerability of multiple oral doses of tipranavir (Aptivus) and ritonavir with a focus on the long term safety of the development dose (500 mg tipranavir/200 mg ritonavir BID) when administered with other antiretroviral medications.
Osteopenia and osteoporosis are increasingly reported in HIV-infected patients, and appear to be more frequent than in general population. However, pathogenesis remains unclear, and published studies still give non concordant results. We therefore started a prospective study, to assess the potential role of ARV in the occurrence of osteopenia and osteoporosis. BMD evolution over a 2-years period of follow-up, will be compared between patients starting ARV therapy, and subjects without HAART (no indication of treatment). A correlation between BMD and several factors will be looked at (see below). This study with individual direct benefice, is conducted in 3 outpatients clinics (Strasbourg, Colmar, Mulhouse) in collaboration with the rheumatologic teams. 60 patients are planned to be included over a 3-years inclusion period
Our goal is to determine if a change in therapy to one containing Kaletra can improve the immune response in patients who have previously been immune partial responders or non-responders. We also are interested in knowing if this agent improves immune response by affecting cluster of differentiation 4 (CD4) + T cell death (apoptosis) or by further inhibiting (preventing) ongoing, low-level, viral replication to levels below detection by current viral load measurements. This will help us understand why immune responses to effective antiretroviral therapy are so different and help determine some possible guidelines for managing patients with poor immune responses. Hypothesis: Patients with poor immune responses to HAART who receive Kaletra in place of their current PI or Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs) while continuing their current 2 NRTI backbone will have improved immune response to therapy compared to patients who continue their current regimen.
Pharmacokinetic study of Saquinavir and Ritonavir in HIV-infected pregnant women
This study evaluated the safety and tolerability of tipranavir to improve treatment options for HIV type 1-infected patients who have been previously treated and whose treatment is no longer effective.
1. In order to obtain further insight as to how NVP affects HDL metabolism, the in vivo kinetics of the HDL apolipoprotein, Apo A-1, before and 6 weeks after initiation of NVP containing treatment were evaluated. In addition, the activity of the key enzymes related to HDL metabolism were assessed. [ Designated as safety issue: No ] 2. In order to determine the relevance of the HDL increase in decreasing cardiovascular risk in HIV-positive subjects we evaluated endothelial function (FMD) as a surrogate marker for cardiovascular disease in patients. [ Designated as safety issue: No ]
The objective of this study was to evaluate the steady-state clearance of nevirapine among HIV-1 positive patients with hepatic fibrosis, and to examine whether the degree of hepatic impairment influences clearance.
To determine whether a regimen of single dose nevirapine combined with either 4 or 7 days of Combivir®, compared to a regimen of single dose nevirapine, for the prevention of mother to child transmission can reduce the rate of development of drug resistant mutations of HIV-1, in HIV-1 infected pregnant women, who have not received antiretroviral therapy previously.
