Active clinical trials for "Acquired Immunodeficiency Syndrome"

This is a Phase IV, open label, observational study to compare the gastrointestinal tissue concentrations, inflammatory response, and viral replication of two integrase-inhibitors, raltegravir and dolutegravir, in HIV-infected volunteers who are virologically suppressed in blood plasma. The study will be comprised of 20 HIV-infected volunteers who will be enrolled equally into two groups. Group A will consist of 10 subjects receiving an antiretroviral regimen of tenofovir, emtricitabine, and raltegravir, and Group B will consist of 10 subjects receiving an antiretroviral regimen of tenofovir, emtricitabine, and dolutegravir. Participants will provide small pieces of tissue, or biopsies, which will be taken from three distinct locations of the large intestine during a colonoscopy procedure. These biopsies will be used to measure the amount of raltegravir or dolutegravir, HIV virus, and inflammatory markers present in the gastrointestinal tract.

Human immunodeficiency virus (HIV) is a major global health concern which has resulted in an estimated 39 million deaths world-wide. Although it is now a treatable medical condition there is still avoidable morbidity and mortality associated with HIV infection in the UK. Late diagnosis (CD4 count of <350 cells/mm3 or AIDS-defining illness irrespective of CD4 count) is associated with increased morbidity and mortality, increased risk of transmission, impaired response to antiretroviral therapy and increased healthcare costs. In Grampian, 49% of patients were diagnosed late between 1984 and 2011. Therefore, the aim of the study is to determine the factors associated with late HIV diagnosis in Grampian between 2009 and 2014 to ascertain whether diagnoses could have been made earlier. The study constitutes a secondary data analysis. Individuals newly diagnosed with HIV between January 2009 and December 2014 were identified from a Health Protection Scotland (HPS) database. The majority of outcome data were extracted from the existing HPS database. Missing data were collected via a retrospective review of patient case-notes, laboratory reports and an electronic patient management system. Patients were classified as early or late diagnosis and comparisons were made between the groups using statistical tests. The study sought to provide a basis for recommendations for improvement of information and services to facilitate earlier HIV diagnosis in Grampian.

The goal of this research is the attempt to implement a new research method based on modern electrochemistry successes, in particular the development of the polarographic method of fructose and fructose diphosphate identification and its implementation to detect the viral infection in early stage. There will be 20 samples from the HIV-infected patients and 30 samples from the heath controls. The study will collect 10ml urine and examined fructose and fructose-diphosphate using the polarographic method.

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.

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.

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 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.
