Active clinical trials for "HIV Seropositivity"

That computed tomography (CT) screening of HIV-seropositive heavy smokers will detect early stage lung cancer at significantly higher rates than what is currently being observed.

This retrospective observational study aims at the examination of regional differences in the procedure of referral for serological HIV testing between eastern (new) and western (old) German federal states.

HIV drug resistance presents a significant public heath problem. This proposal is designed to explore the association between ongoing illicit drug use and the prevalence of HIV drug resistance among HIV+ opioid dependent patients receiving opioid agonist treatment with the following hypotheses: Hypothesis 1: The prevalence of HIV drug resistance will range between 10% and 30%. Hypothesis 2: Patients with evidence of ongoing illicit drug use will be more likely to have HIV drug resistance.

The ageing process is known to be accelerated in HIV-infected patients, compared to the general population. Normal age-related hearing loss (presbyacusia) is a frequent phenomenon, affecting more than 70% of people above 65 years. It is believed to be mostly the consequence of a mitochondrial damage caused by oxidative stress. Risk factors for accelerated age-related hearing loss are present in many HIV-infected patients : chronic inflammation, smoking, diabetes, etc. The global aim is to measure the prevalence of presbyacusia in a well controlled HIV positive population in France, and to compare it to HIV negative controls matched for age and sex. 90 HIV positive patients and 90 age- and sex- matched HIV negative controls will undergo a screening for presbyacusia (pure-tone, speech and evoked-response audiometry). We expect to find an increased prevalence of presbyacusia in HIV-infected patients, as compared to controls matched for age and sex.

The lack of success in treating substance abuse may be contributed to by a limited understanding of the clinical neurobiology of drug abuse. A better understanding of such deficits might aid in the development of more relevant pharmacological and psychosocial treatment approaches. Thus, the purpose of this study is to test the hypothesis that repetitive illicit drug use may be associated with cortical and subcortical structural abnormalities, vascular abnormalities, as well as neuropsychological decrements. Additionally, a battery of psychological tests are administered to provide information about demographics, drug use, neurocognitive measures, and personality structures....

This is a qualitative study using a purposive sampling methodology to interview HIV-positive female adolescents who have experienced physical and/or sexual abuse. An open-ended, in-depth interview, occurring over one to two sessions, will be conducted with each participant.

The program " Au labo sans ordo " aims to increase HIV testing coverage, in order to improve the first stage of the HIV care cascade in Paris and the Alpes-Maritimes, areas facing a much higher HIV epidemic than the other regions in metropolitan France. Both departments are engaged in the Fast Track Cities Initiative.

In summary, in this project the investigators propose to study the proviral DNA genotyping to implement a lower cost and wider than the commercial systems currently in use, in order to analyze all HIV genes that are therapeutic targets of antiretroviral drugs. Using HIV proviral DNA we can obtain information for: HIV-1 Viral Tropism, Mutations associated to Integrase Inhibitors, Mutations associated to Transcriptase reverse Inhibitors, Mutations associated to Protease Inhibitors, and Mutations associated to GP41 Inhibitors. Along with this the investigators propose to validate the proviral DNA as starting material for genotyping which is independent of the patient's viral load and achieve a greater number of patients living with HIV have access to this important test that is essential in monitoring the HIV infection. 3.2 RESEARCH QUESTIONs Is proviral DNA a genetic compartment suitable for carrying out a genotypic resistance test in patients with low or undetectable viral load? Does proviral DNA have the same clinical validity that RNA? 3.3.- HYPOTHESIS A resistance genotyping test carried out by Proviral DNA detects the same mutations associated to resistance that viral RNA. 3.4.- OBJECTIVES: General/Specific General objective Develop a methodology to assess the proviral HIV-1 DNA or RNA as the genetic material for genotyping assays in genes that are targets of pharmacological interest as TR reverse transcriptase and protease (PRO), Integrase or GP41 Inhibitors and HIV tropism. Specific Objectives 1. Carry out genotyping by proviral DNA and compare it with the same genes genotyping performed with viral RNA. 2. Once the correlation between proviral DNA and RNA has shown, standardize a method to use the technique for clinical use in monitoring HIV patients according to each patient's needs. RNA for patients with viral load above 1,000 copies/mL. Proviral DNA for patients with low or undetectable viral load.

The purpose of this study is to identify medical conditions that may cause particular problems to individuals receiving care for HIV infection over the age of 50. In addition, as the effects and potentially the side effects, of HIV medication may change with age, this study will also investigate the association between age and differing effects of antiretroviral therapies such as treatment outcomes, side effects and the levels of drugs in blood. Results from this study may inform future HIV treatment guidelines on how we monitor individuals with HIV infection. The results may also assist in the design of future studies for the treatment of diseases associated with ageing.

This cross-sectional survey will be conducted prospectively in 2 communes in the Battambang Province, Roka and Prey Khpos commune. The principal objective of the study is to compare HIV and HCV prevalence rates in three groups of subjects as follows: Group 1: subjects living in Roka and Ambaeng Thngae villages where most of HIV and HCV cases were identified during the Roka outbreak in 2014-2015 Group 2: subjects living in the other 4 villages of the Roka commune (Ta Haen I and II, Pou Batdambang, and Chhung Tradak) Group 3: subjects living in selected villages from Prey Khpos commune 1,098 eligible residents will be selected using three-stage cluster sampling method. A structure questionnaire will assess the medical injection practices through face-to-face interview. The study will be conducted into two steps. The first step will be a prevalence study to assess HIV and HCV prevalence rates in three groups of subject; Group 1: subjects living in Roka and Ambaeng Thngae villages where most of HIV and HCV cases were identified during the Roka outbreak; Group 2: subjects living in the other 4 villages of the Roka commune (Ta Haen I and II, Pou Batdambang, and Chhung Tradak) and Group 3: subjects living in villages from Prey Khpos commune).The second step will be the phylogenetic study of HIV. The phylogenetic study of HIV will be performed ONLY if HIV prevalence rates among group 2 and/or group 3 is higher or equal to 0.7% (upper limit of confidence interval of HIV prevalence estimated in Cambodia)
