Active clinical trials for "Acquired Immunodeficiency Syndrome"

The aim of this single centre study is to measure maternal CD4+ t-cells in HiV exposed Newborns after spontaneous birth in comparison to cesarean section. This may have an influence on the risk of vertical HiV transmission.

Purpose: To see how growing older changes the amount of HIV drugs in the blood of HIV-infected men and women. Many changes happen in the body as it ages that may affect the way drugs are carried in the blood, broken down or removed from the body. This study will look at the amount of drug in the blood and cells of the immune system for patients taking efavirenz, tenofovir and emtricitabine or atazanavir boosted with ritonavir, tenofovir and emtricitabine. Participants: The population will comprise of 56 (6 for intensive PK and 50 for sparse sampling) HIV-infected adults currently adhering to an antiretroviral regimen containing efavirenz with tenofovir and emtricitabine and the same number and distribution of HIV-infected adults currently adhering to an antiretroviral regimen containing atazanavir boosted with ritonavir with tenofovir and emtricitabine. Procedures (methods): This study will be completed at the University of North Carolina at Chapel Hill. There will be four groups of subjects: Efavirenz/tenofovir/emtricitabine Group A, Efavirenz/tenofovir/emtricitabine Group B, Atazanavir/ritonavir/tenofovir/emtricitabine Group A, and Atazanavir/ritonavir/tenofovir/emtricitabine Group B. The initial six subjects (Group A) for intensive PK analysis for each regimen will be recruited from the the UNC ID Clinic or the Moses Cone Health System Infectious Diseases Clinic, and will be comprised of non-frail subjects not currently receiving interacting drugs. If subjects provide informed consent, timed blood samples will be obtained to determine pharmacokinetic parameters around an observed dose of one of the two study regimens. A whole blood sample will also be collected and stored for potential drug metabolizing enzymes and transporters genotyping in the future. Group A subjects will complete a follow-up visit after their sampling visit. 50 subsequent subjects (Group B) for each regimen will be screened simultaneously, with no more than 10 subjects enrolled for each regimen in Group B prior to the completion and analysis of Group A. These subjects will also be recruited from either site. Group B subjects will have one or two sampling visits with 1 to 4 blood samples obtained at each visit, with a stored sample for future genotyping obtained on one of the visits. Samples will be collected just prior to a dose, at 2 hours, between 4 and 6 hrs, and between 10 and 14 hours after a medication dose. These visits may coincide with the subjects' regularly scheduled visit to the clinic, or be scheduled separately, depending on the preference and availability of the subject.

This US population-based study will explore the incidence of and risks for fracture among adults with and without human immunodeficiency virus (HIV) infection. The objectives are to determine the incidence of fracture among persons with and without HIV infection, compare risk factors for fracture among persons with and without HIV infection, and to examine the associations of antiretroviral (ARV) treatment exposure for incidence and risk of fracture among persons with HIV infection.

The aim of this study was to delineate the epidemiological profile of HIV seropositive patients on antiretroviral therapy at the Clinical Hospital of the Federal University of Goiás.

The study of early, acute HIV infection is critical to understanding subtype-specific pathophysiologic differences, since up to 50% of acute HIV infections may be incapacitating. This study will establish whether the patient population of the Thai Red Cross Anonymous Clinic is suitable for the study of early, acute infection.

The purpose of this study is to collect data and body fluid samples from people with acute or established HIV infection and from HIV uninfected people. Data from this study will be used to better understand properties of HIV, including HIV transmission and the differences between acute and established HIV infections.

This study will use focus groups and in-depth individual interviews to explore factors that influence the decision of Hispanics and African-Americans with HIV/AIDS to participate in a research study. HIV-positive Hispanic and African-American patients 18 years of age and older who are enrolled in an NIH HIV/AIDS protocol may be eligible for Part 1, Part 2, or both parts of this study, as follows: Part 1 - Focus group Focus group participants of from six to ten people are interviewed together during a one-time, 2-hour tape-recorded session to explore how they arrived at their decision to enroll in a research study. The group discussion is led by a moderator and a facilitator. Before the session begins, participants complete questionnaires that include information about their age, race, ethnicity, education and social support. Hispanic participants also complete a questionnaire about language preference. At the end of the focus group, participants are offered to be interviewed individually, as described below. Part 2 - In-depth interview An investigator conducts a one-on-one in-depth interview with the participant while a second person observes and tape records the interview. The interview may take from 1 1/2 to 2 hours to complete. Participants who were not in a focus group are asked to complete questionnaires as described in Part 1 above.

To provide early access to tipranavir and evaluate the safety and tolerance of tipranavir combined with low dose of ritonavir in patients with progressive, HIV-1 disease who have failed or are intolerant to currently approved treatments for HIV infection, who are unable to participate in another tipranavir controlled clinical trial and have an urgent need for anti-HIV treatment.

This trial studies the frequency of incident and prevalent of cancer in people living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) at cancer centers in Latin America. By counting how many people living with HIV/AIDS have cancer at these specific centers, researchers may better understand how they are being treated and cared for. This may help researchers to understand what new studies may be helpful for those areas in the future.

STRIDE2 is a longitudinal, non-randomized study of individuals living with HIV who are dependent on opioids. This study is funded by the National Institute on Drug Abuse (R01DA030768, Altice, PI; Taxman & Lawson, Co-PIs) and is being conducted by George Mason University, Yale University, and Howard University.
