Active clinical trials for "Acquired Immunodeficiency Syndrome"

The purpose of this study is to compare the results for HIV and/or Hepatitis C Virus antibody testing when using routine plasma versus SMARTplasma from the same blood sample. SMARTplasma is enriched for antibodies via a stimulation step of whole blood in a SMARTube™ (SMARTstim™ in the USA).

Group A: Long-term follow-up is needed for subjects identified as acute or early in the course of HIV-1 infection, independent of decisions regarding therapy with highly active anti-retroviral therapy (HAART). Group B: This protocol will also be offered to subjects who were diagnosed with acute HIV-1 infection in the past and have been participating in an ADARC/Rockefeller University Hospital treatment protocol for acute HIV-1 infection, and currently have a viral load consistently less than 50 copies/ml on current treatment (Group B)

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

To determine the incidence of tuberculosis in an inner city population, identify risk factors for TB, describe the natural history in adults and children, evaluate the effect of Mycobacterium tuberculosis (Mtb) co-infection on the progression of human immunodeficiency virus disease, and determine factors that contribute to compliance and non-compliance with prophylaxis and treatment.

To determine the prevalence and natural history of pulmonary and cardiac complications associated with HIV infection in utero, in infancy, and during early childhood.

To evaluate factors influencing the risk of transfusion-transmitted human immunodeficiency virus (HIV) infection and its progression to clinically significant manifestations.

The purpose of this study is to find out if it is effective to give aggressive anti-HIV therapy to patients who have been infected recently with HIV. Many doctors recommend that patients who have recently been infected with HIV begin anti-HIV treatment as soon as possible. However, early HIV infection is not yet completely understood, so it is not known if this is the best approach. This study will look at the effects of beginning anti-HIV treatment during early HIV infection.

The purpose of this study is to find out why cancers develop in HIV-positive patients. Cancer is a leading cause of death in AIDS patients. Common cancers in HIV-infected patients include Kaposi's sarcoma (KS) and non-Hodgkin's lymphoma (NHL), a cancer of the immune system. Risk factors include certain chemicals, viruses, and perhaps even anti-HIV drugs. Doctors would like to find out which risk factors are most important and how they relate to cancer in AIDS patients.

Children and adolescents with HIV/AIDS are living well beyond life expectancy that was projected for them in the recent past. Little is known about the psychosocial variables that coincide with long-term survival of HIV/AIDS. This longitudinal study examines the psychosocial factors and adaptive coping strategies associated with long-term survival of HIV/AIDS in children and how these factors change over a period of two years. In addition, data is being collected from the primary caretakers on their own psychological well-being as will as their perceptions of their child's adjustment and coping. Participants include children who have been infected (either perinatally or through transfusion) for at least eight years and who were aware of their diagnosis.

This study will examine how quickly white blood cells called CD4 lymphocytes reproduce and how long they live in people infected with HIV. It will do this using bromodeoxyuridine (BrDU), a compound that is structurally similar to thymidine, one of the building blocks of DNA. BrDU gets incorporated into DNA instead of thymidine, but it can only get into cells that are replicating. Therefore, measuring the proportion of cells with BrDU indicates how many cells are replicating. HIV-infected patients 18 years of age and older may be eligible for this study. Candidates will be screened with a medical history, physical examination, chest X-ray, electrocardiogram (EKG) and blood tests. Participants will be given an infusion of BrDU through a catheter (thin plastic tube) placed in an arm vein. Blood will be drawn up to 4 times in the first 24 hours after the infusion. Additional samples will then be collected as often as daily for the first week, twice a week for the next 3 weeks and then weekly to monthly for up to 1 year. Some patients may undergo a tissue biopsy (removal of a small tissue sample from a lymph node, tonsil or colon) or computed tomography (CT) scans of the thymus (a small gland between the lungs that manufactures lymphocytes. Some patients will have a second infusion in order to examine changes in the rate of CD4 replication over time or following potent antiretroviral therapy. Patients will be followed in the clinic periodically for the first year and then will be seen in the clinic or contacted by telephone once a year for 4 more years. The results of this study may provide a better understanding of how HIV causes disease and how therapy affects the immune system.
