Active clinical trials for "Acquired Immunodeficiency Syndrome"

The purpose of this study is to study the kinetics (study of the rate of change) of immune recovery quality and function in stored plasma blood samples of treatment-naive (not previously treated with antiretroviral drugs) patients with advanced human immunodeficiency virus (HIV) infection starting a Darunavir/Ritonavir- or Efavirenz-based highly active antiretroviral therapy (HAART) regimen.

The aim of this study is to find out if the process of HIV replication in the lymph tissue and gut tissue of people taking HIV drugs causes long-term damage to the ability of the gut to protect you from other infections and health problems.

The purpose of this study is to describe the epidemiology of pulmonary hypertension in individuals with HIV infection and to investigate its pathogenesis. We propose to conduct a prospective observational cohort study to determine the association between highly active antiretroviral therapy (HAART) and viral suppression in HIV-infected patients who have been identified to have pre-clinical pulmonary hypertension (Aim 1). In addition, we will investigate the mechanistic role of the HIV-1 Nef protein and HHV-8 infection in the development and progression of pulmonary hypertension in individuals with HIV (Aim 2). We will also investigate endothelial function in HIV-infected patients with pulmonary hypertension (Aim 3).

This is a study to determine the prevalence of a genetic marker, HLA-B5701, in the UK population. HLA-B*5701 has been strongly associated with the risk of an allergic reaction to a HIV medicine, Abacavir. The allergic reaction is known as a hypersensitivity reaction. The study is a prospective study inviting HIV-1 positive patients over the age of 18 years to participate. Each participant will complete one study visit. They will be asked for details of their background including their age, sex, ethnicity, country of origin and parental country of origin. They will be asked to give two samples to test for the presence of the genetic marker HLA-B*5701. The two samples are: A cheek swab A blood sample In selected centres patients may be asked to provide up to two additional blood samples. These samples will be used to help develop and validate new methods of determining HLA-B*5701 testing.

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.

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.

To determine the seroprevalence of Kaposi's sarcoma-associated herpesvirus (KSHV/HHV8) in blood donors from Texas. Also to examine the donors' demographic characteristics and to characterize the KSHV using polymerase chain reaction.

The purpose of this study is to monitor patients who recently have been infected with HIV in order to learn how their immune systems respond to HIV infection and to study how the virus acts in their bodies. Primary HIV infection occurs within 20 days to 8 weeks following exposure to HIV. The symptoms of primary HIV infection are usually fever, tiredness, headache, or muscle aches. However, symptoms vary greatly from person to person, and some people might not experience any symptoms at all. Because these symptoms also resemble the cold or the flu, it is difficult to identify patients with primary HIV infection. Information gathered from this study will help doctors decide what kind of treatment is best to give patients who recently have been infected.
