Active clinical trials for "HIV Infections"

The purpose of this study is to perform cardiac evaluation in HIV-1 (predominantly clade C)infected children by history, physical examination, echocardiogram and plasma N-terminal pro-B-type natriuretic peptide (N-BNP)measurement in order to determine asymptomatic abnormalities.

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.

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.

The response to vaccination for hepatitis is reduced in patients with HIV infection. The hypothesis of the study is that adjuvant interleukin-2 administered subcutaneously at the time of vaccination improves the response rate.

Patients with HIV an have a variable course of their infection. We are trying to identify factors which worsen or ameliorate the course of the disease. Such factors may be related to metabolism (breakdown) of drugs or to iron handling by the body.

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.

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.

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.

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.

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.
