Active clinical trials for "HIV Infections"

This is a multicenter, open-label, non-randomized, dual-arm pilot study to investigate the prevalence of the reverse transcriptase (RT) resistance mutations, K65R/x or L74V/x, in HIV-1 plasma from subjects experiencing confirmed first-time incomplete virologic suppression during treatment with an initial antiretroviral (ARV) regimen consisting of at least 12 weeks of TDF or ABC + emtricitabine (FTC) or lamivudine (3TC) + non-nucleoside reverse transcriptase inhibitor (NNRTI) or protease inhibitor (PI). Subjects will be followed until a substantial loss of virologic or immunologic control requires a treatment switch. Confirmed first-time incomplete virologic suppression is defined as an initial plasma HIV-1 RNA response < 400 copies/mL, and subsequent virologic rebound > 400 copies/mL measured at two consecutive times. Subjects will have a screening genotype to establish adherence to their non-suppressive TDF- or ABC-containing regimen by the presence of M184V (or other treatment-related primary) mutation and to demonstrate that the evolution of treatment-emergent RT mutations can be characterized. Twenty subjects (a maximum of 10 per arm) will be enrolled at 10-20 United States (U.S.) sites. If fewer than 20 subjects can be enrolled, the study may be discontinued early by the sponsor. Equal numbers of subjects on Arm A versus Arm B will be a goal.

The purpose of this study is to determine how often dementia and other neurological problems occur in people with HIV. Participants of ACTG A5175 will enroll in this study.

This study is assessing the extent of spirituality in patients with HIV/AIDS and will determine the relationship between spirituality, health status, and the will to live.

The purpose of this study is to explore the association between blood pressure, HIV and/or its treatment in a cross sectional observational study.

The goals of this study are to: determine the diarrheal rates, morbidity, mortality, and pathogens present among breast-fed infants born to HIV-infected mothers. analysis by HIV status of infants, method of feeding, HIV viral loads / CD4 counts of infected mothers. comparison to rates among infants born to HIV uninfected mothers. link analysis of the functional quality of immunoglobulins in the breast milk of HIV-infected and uninfected mothers.

To establish the incidence, clinical spectrum, and natural history of cardiac dysautonomia as defined by heart rate spectral analysis in both HIV infected and noninfected children and to evaluate the value of heart rate spectral analysis for predicting dysrhythmias and sudden death in infants and children born to HIV infected mothers.

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.

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.

The purpose of this study is to determine the risk factors associated with the occurrence of arterial insufficiency in patients with HIV / AIDS, and to identify the prevalence of this disease. The estimated prevalence is 10%, similar to that reported in the general population.

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
