Active clinical trials for "HIV Infections"

Data collection for better patient characterization in a highly treatment experienced population. Studying the clinical practice for the treatment of HIV multiexperienced patients in the real life. The research will be divided into two phases: The first phase intends to define and understand the clinical practice using a questionnaire about general topics: definitions of multiexperienced patients and VL failure, therapeutic strategies and behaviour in particular cases. The second part of the research will collect the clinical data of double PIs failure patients.

The purpose of this study is to find out how people's needs are being met and what people do about problems with treatment, symptoms, substance use, mental health, and social services. We are also interested in finding out about changes that people make in their health care team and the reasons for making those changes.

The purpose of this study is to provide early access to TMC114 (a protease inhibitor) for HIV-1 infected patients with limited or no treatment options, who have failed multiple antiretroviral (ARV) regimens, and to evaluate the longer-term safety and tolerability of TMC114/r in combination with other antiretrovirals

The purpose of this observational study is to estimate the number of new HIV infections and the number and variability of antiretroviral-resistant HIV strains among men who have sex with men (MSM). Participants will be recruited from four sites in Peru and one site in Ecuador.

This study will compare the response of subjects who failed a first-line ATV-containing regimen and who have the 150L-containing virus to subsequent protease inhibitor (PI)-containing therapy with that of a cohort who has failed a first-line reverse transcriptase inhibitor (NNRTI), and is subsequently receiving PI-containing therapy.

This study is being conducted to assess the safety and tolerability of an oral liquid solution of Sustiva for antiretroviral therapy-naive or therapy-experienced HIV-1 infected children between the ages 3-16 who are failing or intolerant of current antiretroviral regimen and who are unable to swallow Sustiva capsules.

A number of factors influence HIV-positive adolescents' acceptance of and willingness to continue taking anti-HIV medicines. These factors include mental health and substance abuse issues, barriers such as lack of medical insurance, and cognitive-behavioral barriers (such as a person's impression of the impact of the medicines on his/her health and a person's sense of his/her ability to continue taking the medications prescribed). The purpose of this study is to use a survey to determine how common specific barriers are that prevent HIV positive adolescents from taking their anti-HIV medicines and if those barriers cluster together. The information collected will be used to develop and validate a schema for classifying HIV medication adherence by barriers to adherence or clusters of barriers to adherence. This classification schema could then be used in the development of interventions that better meet the needs of HIV-infected youth.

The purpose of this study is to find out the frequency of the I50L substitution among patients experiencing treatment failure on an atazanavir-containing regimen.

The aim is to investigate the hypothesis that IL7-receptor polymorphisms contribute to the differential immune recovery of CD4 + T cells following HAART

Some people's immune systems are able to control HIV infection without anti-HIV drugs. Other people with HIV must take drugs to prevent the virus from destroying their immune systems. There are many different laboratory tests that measure immune function in people with HIV. This study will compare some of these tests to see if they consistently measure differences between people who control the HIV without anti-HIV drugs and those who must take drugs.
