The investigators propose to develop and evaluate optimal combinations of evidence-based interventions to improve HIV outcomes and reduce methamphetamine use (hereafter: meth use) among people with opioid use disorder who are in methadone maintenance therapy (MMT) in Vietnam. Over the past decade, the expansion of MMT has contributed to stemming both HIV and opioid epidemics. However, rising meth use threatens these achievements. Evidence-based interventions such as Motivational Enhancement Therapy, Contingency Management, Matrix Model, and SMS reminders are effective in reducing meth use. The study will be conducted in the two largest cities in Vietnam, Hanoi and Ho Chi Minh City (HCMC), where there are the highest number of MMT patients and the highest burden of HIV cases. Building on the pilot work of the research team in Hanoi, through collaborative work with local MMT providers and patients, the investigators will first further refine adapted EBIs to develop adaptive strategies. The adaptive design includes: (1) Two frontline interventions: 6 weeks of contingency management then 6 weeks of weekly group educational sessions and 12 weeks of contingency management; (2) One (short-term) tailoring outcome: urine tests negative with meth metabolites in both week 11 and 12 are considered responsive to frontline interventions; (3) Three alternative interventions: those with positive outcomes will move to 12-week maintenance stage and receive two daily SMS reminders plus one weekly self-monitoring assessment messages. Non-responders will move to 12-week enhanced treatment stage and are randomly assigned to either Matrix group counseling only or Matrix group counseling plus contingency management. The full randomization trial will be conducted with 200 HIV-positive and 400 HIV-negative MMT patients who report moderate- and high-risk meth use on self-screening with ASSIST or have urine positive with meth metabolites. In each location, the study will stratify participants by HIV status before randomizing them to one of two frontline interventions. Primary outcomes - including HIV viral suppression, HIV risk behaviors, and meth use (reported and urine tests) - will be assessed at 12, 24 and 48 weeks. The study team also conducts ethnographic observations and in-depth interviews with MMT clinic managers, clinical staff and MMT patients to explore implementation barriers and facilitators.
NCT05571319
Metabolic syndrome is a constellation of risk factors for cardiovascular disease and type 2 diabetes mellitus which frequently occur together. Data is emerging suggesting metabolic syndrome causes brain disease by contributing to blood vessel damage and inflammation. People living with HIV (PLWH) are at high risk and the investigators will perform a pilot study of the well-known type 2 diabetes drug metformin to treat this blood vessel damage and inflammation in PLWH.
NCT05306249
Autophagy and apoptosis are natural cellular mechanisms which consist for the first in a recycling and elimination process of potentially toxic cellular waste, and for the second in a process of cellular suicide when it becomes abnormal and "not" repairable, notably by autophagy. A deficit in autophagic function at the cellular level can lead to chronic inflammation and accelerated cellular senescence. Apoptosis is a beneficial phenomenon because it eliminates abnormal cells that could endanger the organism if it survives (e.g. karyotypic atypia). Uncontrolled, it can be deleterious if apoptosis is hypo or hyperactive.
NCT04682990
Tuberculosis (TB) is one of the top 10 causes of death in the world. More than 95% of TB deaths are in middle- and middle-income countries. Low incomes and long-term diagnosis promote this persistence. In 2017, Cameroon was the 3rd in the top of 20 countries with the highest estimated numbers of incident TB cases among people living with HIV, based on the severity of their TB burden. World Health Organization (WHO) encourages the introduction of rapid, non-invasive and cheaper screening tests. In this scope, this study proposes the collection of exhaled breath samples and their analysis through the electronic nose made in Tor Vergata University (TV eNose) to diagnose TB and TB-HIV on their participants.
NCT03374358
This study will provide data on the switch from a protease inhibitor or efavirenz to the new formulation of raltegravir (RAL) dosed once daily. The study group consists of patients with metabolic risk factors and co-morbidities, in need of optimization of their current ART to minimize the drug-related metabolic side effects as standard of care. The primary objective of this study is to investigate whether switching a protease inhibitor (PI) or efavirenz to raltegravir once daily reduces liver fat in patients who are overweight or obese and have at least one metabolic syndrome component. For this purpose, the liver fat content will be analyzed using the proton magnetic resonance spectroscopy. In addition, the aim is to clarify the change in the body composition and metabolism in this study group. For this purpose the visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) volumes will be measured and subcutaneous tissue samples will be collected for future analyses of adipose tissue function.
NCT03158987
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.
NCT02154971
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.
NCT03661203
The present study will try to investigate and analyze the psycho-social hindrances and levers concerning the recourse to late HIV testing among the MSM population. This study is divided in two parts. The first one will consist of individual and groups interviews. Then, depending on the items that will rise from the first part of the study, groups interview will take place based on theses items. Finally, a questionnaire build from the collected information will be sent to MSM community in order to obtain quantitative results.
NCT04030689
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.

NCT04088916
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.

NCT00130819
The purpose of this study is to compare the effectiveness of two approaches to treating HIV-infected patients who are addicted to opioid drugs (e.g., heroin) in an inner-city HIV clinic. The two approaches are: * Case management and referral - participants are managed by a case manager and referred to a specialized drug treatment center where they receive counseling and medications for opioid-dependence (e.g., methadone or buprenorphine); or * Clinic-based treatment - participants receive counseling and treatment with buprenorphine at the HIV clinic.

NCT01733927
The purpose of this study, conducted in Santiago-Chile, was to: 1. Evaluate the sensitivity and specificity of OraQuick Advance oral rapid test (OQA)when compared to ELISA; 2. Track the number of people in the study who returned for their ELISA test HIV results; and 3. Analyze the perception among participants of the use of OQA compared to ELISA testing for HIV screening.
NCT01174914
In the vast majority of those infected with HIV virus who are untreated, there is deterioration in immune health over a period of months or years inevitably leading to full-blown AIDS and demise. Treatment with ARV's stop or slow down this deterioration if started before a certain degree of progression occurs and has saved millions of lives. The investigators' study hypothesis is that effectiveness of a very low dose of an FDA-approved medication, naltrexone hydrochloride, (Low-Dose Naltrexone, or LDN) will compare favorably to ARV's to prevent progression of HIV+ toward immune deterioration and full-blown AIDS.
