Active clinical trials for "Acquired Immunodeficiency Syndrome"

Kaohsiung Medical University Chung-Ho Memorial Hospital will provide a long-term free medical service in Indian Tibetans since July 2010. The investigators plan to investigate metabolic syndromes and HIV infection in Indian Tibetan community. The investigators will survey the prevalence and risk factors by means of HIV quick test and questionnaires. Since there is lacking of prevalence survey for metabolic syndrome and HIV infection in Tibetan colony of India, the investigiators will carry out this survey under the support and assistance of Department of Health of Central Tibetan Government.

The proposed study is a substudy of ATN 106 and a cross sectional study intended to be conducted at each of the AMTUs newly participating in ATN III. The intent is to enroll all youth with behaviorally-acquired HIV who have enrolled in ATN 106. The study involves a review of the subjects' medical chart and a collection of an oral rinse sample.

This is a pilot study with a cross-sectional research design to recruit Hispanic/Latina and African American adolescent and young adult women, aged 13-24 years to serve as index recruiters, who will in turn recruit members of her female friendship network, aged 13 years and older to undergo HIV screening. This approach seeks to identify new HIV infections in the target population.

This study will collect information on health status and risk behaviors, as well as basic demographic and biomedical information for a group of HIV positive adolescents receiving care at sites newly participating in ATN III.

The purpose of this study is to learn whether HIV-infected patients have blood abnormalities which could lead to heart attack or stroke, and to find out what factors may contribute to these abnormalities.

To further investigate differences in the immunologic function of various lymphocyte subsets in HIV-infected patients who are treated early in their infection and during the chronic phase of the infection. Studies will also be done to further delineate the various antigen-specific and innate immune responses including characterization of soluble factors associated with primary HIV infection.

To evaluate the types, incidence, course, and outcome of pulmonary disorders in newly diagnosed cases of Acquired Immune Deficiency Syndrome (AIDS), newly diagnosed cases of AIDS-related complex (ARC) and newly diagnosed asymptomatic human immunodeficiency virus (HIV) infection.

Patients enrolled in this study will not receive investigational therapy. Any treatments rendered will be standard and based on appropriate medical care. Should a patient become eligible for an experimental therapy protocol, the normal process of enrollment and informed consent will be followed.

This will be a two-arm cluster randomized controlled trial. The control group can share their Center for Disease Control and Prevention certified online HIV results (COHIV) with another party freely through a social networking tool, while the intervention group will be asked for the COHIV before he can see the COHIV of his friend. The investigators hypothesize that the requires exchange will promote HIV testing and thus reduce HIV incidence among MSM.

Research question Is there any association between altered lung bacterial communities and HIV-associated Chronic Obstructive Pulmonary Disease (COPD)? Rationale Sub-Saharan Africa has experienced dramatic increases in COPD related-morbidity and mortality. Longitudinal studies have shown that people living with HIV develop worsening airflow obstruction with a prevalence higher than that of the general population (i.e 3.4 to 21% compared to 0.4 to 12.2%). It is still unknown why HIV-infected individuals develop COPD at a prevalence higher than their HIV-negative counterparts. It's been hypothesized that a change in the lung bacterial communities in the setting of HIV drives inflammation leading to lung damage. There is a need to explore the dynamics of lung bacterial communities and elucidate mechanisms responsible for irreversible lung damage that may follow lung disturbances in bacterial richness and diversity. In addition, understanding the bacterial communities of the lung in normal subjects is an essential step in providing negative controls to interpret lung microbe in disease states for-example COPD. Insights from this research will inform efforts to design optimal screening and treatment strategies for COPD in the HIV-infected population in sub Saharan Africa. Methods A cross sectional study will be conducted in which lung bacterial communities in 63 HIV infected participants ≥ 35 years with and without COPD will be compared with 63 HIV negative participants with and without COPD. Participants will be recruited from COPD/HIV and LINK Nakaseke cohorts, which were population based studies conducted in the same study setting. Sputum samples will be collected using sputum DNA collection, preservation and isolation Kits. Extracted bacterial DNA will be sequenced and used to determine all bacterial species in the processed samples using available online metagenomics databases. Analysis plan A histogram will be used to display the frequencies of the identified bacterial species in the processed samples. Bacterial richness and diversity of samples in the 4 groups will be compared to determine any differences.
