HIV-1 Specific Immune Responses in Thai Individuals With HIV Dementia

HIV Infections

A total of 60 participants will be enrolled. They will be in 3 groups ARV-naïve, HIV-positive ≥ 20 year of age with HAD (n=25) who intend to start ARV ARV-naïve, HIV-positive ≥ 20 year of age without HAD (n=25), who intend to start ARV HIV-negative ≥ 20 year of age (n=10). The protocol team will work with the primary care physician to ensure that the subjects receive standard HIV and ARV care; however, initiation of ARV is not a requirement of the study and ARV will not be provided by the study. Participant accrual will include 10-15 participants per year. HIV-positive subjects will be tentatively enrolled in HAD vs. non-HAD groups by the enrolling neurologist and subsequently confirmed to that group by a consensus conference held every 6 months by the study neurologists. In cases of disagreement, cases will be re-assigned to the consensus conference determination and recruitment will continue. An external validation consensus conference will be conducted as well every 6-12 months to monitor correct assignment of the level of impairment.

A Comparison of Virco®TYPE HIV-1 Testing Versus Expert Interpretation of Genotypic Results for Control...

HIV-1HIV Infections

The investigators seek to determine whether Virco®TYPE HIV-1 provides benefits equivalent to those provided by local expert review. The investigators propose that clinic patients of the Ruth M. Rothstein CORE Center who are having genotypic testing performed will be randomized in a 1:1 fashion to local expert review and to Virco®TYPE HIV-1. Results of either method will be shared with primary HIV care providers. Patient outcomes will be reviewed at a time point equal to or greater than 2 months and 6 months following the change in antiretroviral medications following the testing

Genetic Factors and Interrelationships for Cancer Risk-Related Behaviors and Complex Traits

Acquired Immunodeficiency SyndromeAlcoholism3 more

We propose to conduct a multifactorial genetic study of cancer risk-related behaviors and other complex human characteristics. The main areas of interest are tobacco smoking, excess alcohol consumption, psychological traits, and HIV/AIDS susceptibility and progression. The subjects will be adult male and female probands who display one or more of the phenotypes of interest together with their brothers, sisters and parents. Information on tobacco and alcohol use, psychological and personality traits, sexual behavior, HIV status and progression, and other characteristics with possible genetic components will be obtained through structured interviews and questionnaires. DNA will be prepared from blood samples and typed for a series of candidate genes chosen for function and for random polymorphic markers. By correlating the genotypic and phenotypic information, we hope to identify individual loci that interactively contribute to many different aspects of human health and disease.

Determination of HIV-1 Production by the Prostate

HIV Infections

Virus present in semen likely contributes substantially to the sexual transmission of HIV. However, the source of HIV in semen is unknown. Some evidence suggests that the prostate may be the source of at least some of the virus in semen. This study is designed to determine whether the prostate may serve as the source of virus in semen by comparing the concentration of HIV-1 RNA in semen donated normally, in semen obtained following prostatic massage, and in expressed prostatic secretions. Finding a source for semen HIV would provide important insights into several aspects of HIV sexual transmission. Since some drugs do not enter the prostate well, the finding that virus is produced in the prostate might suggest the prostate could serve as a reservoir for HIV, leading to the development of resistance to antiviral agents.

Seroprevalence of Chikungunya at the End of the First Chikungunya Outbreak in the French Antilles...

HIV InfectionsChikungunya Virus Infection

Late 2013, the first indigenous cases of chikungunya have been observed in the French Antilles. At the end of May 2014, almost all of the islands of the Caribbean were affected by the outbreak. During the large epidemic which affected the Island of La Réunion in 2005/2006, the attack rate was 38%. The most active period was three months. In this context, knowledge of the attack rate and the epidemic in the Caribbean is an important issue for outbreak management and modeling work. As the chikungunya virus had never circulated in the Caribbean, determining the seroconversion rate can be achieved by realizing a seroprevalence survey among the general population at the end of the outbreak. Another simple method is to estimate the rate in a cohort of patients followed regularly and whose habitat is distributed throughout the territory studied. The follow up of patients infected by the human immunodeficiency virus (HIV) in the French West Indies is almost exclusively performed in hospitals in department of Infectious and Tropical Diseases.The high prevalence of HIV and homogeneous distribution of infected patients on all of our territories, allow to hypothesize that the risk of transmission of arboviruses by exposure to mosquito bites is comparable to the general population. This patient cohort is well suited to study the emergence of Chikungunya in the French West Indie . Primary objective : To estimate the cumulative incidence at the end of the first Chikungunya outbreak in the French West Indies by estimating the prevalence of specific antibodies of chikungunya virus in a sample (randomly constituted) from patients infected by HIV and representative of the general population of Martinique and Guadeloupe Secondary objective : To estimate the frequency of asymptomatic infections by the chikungunya virus in the studied population To estimate the frequency of chronic forms of chikungunya in the studied population

Disability and HIV: Vulnerability of People With Disabilities to HIV Infection in Sub-Saharan Africa...

HIVReproductive Health1 more

According to the recent World Report on Disability, around 15% of the world population lives with a disability and 80% of people with disabilities (PWD) live in developing countries. More and more evidence show that PWD are more likely to be poor, vulnerable to physical and sexual violence, and to have less access to education. Therefore, PWD are likely to have an increased risk for HIV infection, potentially being a key population in regard to this epidemic. The vulnerability of PWD was recognized in 2007 by the United Nations Convention on the Rights of Persons with Disabilities. However, data on the extent how PWD are affected by HIV is still very limited. As a result, PWD are usually overlooked by National AIDS Control Programmes and few projects specifically targeting them have been developed. Recognizing the need for appropriate and reliable data to help protect the rights of PWD and achieve a better inclusion of disability in National AIDS Control Programmes, the Institute of Research for Development (IRD), the Institut de Formation et Recherche Demographique (IFORD) and Handicap International (HI) propose this study that aims to provide quantitative and qualitative data on the vulnerability of PWD to HIV infection in Cameroon and Burkina Faso, in order to define if this vulnerable population is also a Key Population in relation to the HIV epidemic. This study adopts a multidisciplinary approach (quantitative and qualitative methods). Quantitative data are collected only in Cameroon. Only the quantitative study is described here.

Accuracy Evaluation of the BD FACS Presto System

Acquired Immunodeficiency Syndrome

The enumeration of T lymphocytes positive for the CD4 antigen is used to determine the immune status of patients with, or suspected of developing, immune deficiencies such as AIDS. The BD FACS Presto™ is an investigational automated system for in vitro diagnostic use in performing the direct enumeration of CD4 absolute count, CD4 percentage of lymphocytes, and hemoglobin (Hb) concentration in human whole blood. This is a prospective study to determine the relative bias between the investigational BD FACS Presto system and the predicate BD FACS Calibur with BD Tritest system in their determination of absolute CD4, % CD4, and Hb concentrations.
