Active clinical trials for "HIV Infections"

The primary goal of this observational study is to evaluate prospective memory in HIV+ patients compared to healthy subjects. The secondary goal is to examine the relationship between prospective memory and Hot Cognition (mechanical cognitive abilities) and Cold Cognition (cognitive abilities supported by emotion and social perception). The main questions it aims to answer are: Do HIV+ patients have more impaired prospective memory than healthy subjects? Is there a greater influence of Hot Cognition on prospective memory than Cold Cognition? Participants will undergo a battery of neuropsychological tests: Memory for Intentions Screening Test (MIST), Montreal Cognitive Assessment (MOCA), Interpersonal Reactivity Index and Modified Five Point Test.

The investigators' main objective is to determine the prevalence of pre-treatment of resistance-associated mutations (RAMs) in a naïve and recently diagnosed HIV infection in 18 centers from 12 cities in Colombia. This evaluation will include the genotyping of all three enzymes, reverse transcriptase, protease, and integrase. This type of complete primary resistance profile has not yet been reported in Colombia and there is only scanty data regarding resistance-associated mutations to NRTIs, NNRTIs, and PIs in the country

Multicenter cohort study of individuals reporting behavioral risks of HIV acquisition, recruited among those presenting for testing for HIV and other sexually transmitted infections. Overarching goal: to study factors associated with uptake of HIV prevention and (re)testing services in medium-sized cities in Thailand. Primary objective: To estimate the incidence of HIV and other sexually transmitted infections (syphilis, chronic hepatitis B and C) among individuals presenting for retesting. Secondary objectives: To evaluate the uptake of pre-exposure prophylaxis To assess retention in the study To evaluate client HIV knowledge To describe HIV prevalence and characteristics of individuals newly diagnosed with HIV To describe characteristics of individuals at risk of HIV infection To assess the quality of the testing and referral services.

Combination interventions with mHealth and Peer Navigation components will be evaluated in a randomized, stepped wedge trial among youth in Ibadan, Lagos, Sagamu, and Jos, Nigeria. Study findings will demonstrate whether or not the combination interventions for HIV testing and linkage to care and for HIV treatment outcomes, which were found to be efficacious in our prior pilot UG3 trial, will remain efficacious if scaled as proposed in this UH3 trial, across multiple sites.

IMPAACT 2028 is an observational prospective study to characterize a cohort of early treated children who may participate in future research related to HIV remission or cure. Up to approximately 250 participants will be in the study for approximately seven years. No intervention is provided in the study.

The purpose of this study is to obtain informed consent to use stored human biological materials (HBM) (e.g., blood and other tissues) for future studies that may include genetic testing.

Patients are frequently evaluated by physicians for medical work-up of HIV indicator conditions in hospital and in primary care at the general practitioner. Testing for HIV is indicated with HIV indicator disorder but often omitted in clinical work-up. Besides the fact that HIV testing is forgotten, there are other reasons such as an underestimation of the risk of HIV in the event of indicator disorders, stigma and difficulties in discussing the test with a patient. Also and more relevant for primary care than for the hospital, practical challenges can exist for a patient to go to a laboratory, or costs are a hurdle. This project focuses on improving HIV indicator condition driven testing in different settings of the HIV epidemic, initially in the Netherlands as low HIV prevalence setting followed by an assessment of its benefit in different international settings. A specific focus will also be on the Rotterdam area in the Netherlands which has a high prevalence of undiagnosed HIV in the Netherlands. The ultimate aim is to decrease the number of undiagnosed HIV in populations, improve the 90-90-90 HIV cascade of care goals particularly its first pillar, and to help supporting the UNAIDS goal to end HIV/AIDS

Background: HIV prevalence and sexual risk have been estimated very high for transgender people. However, the limited sampling and data collection methods used in current research on transgender people potentially led to overrepresentation and generalisation of people at risk for HIV. Current HIV prevalence estimates in transgender populations are generalised from studies mainly focusing on transgender women who engage in sex work. Moreover, current research remains cisnormative, and studies focusing on non-binary people, who identify with a broad range of identities beyond the traditional male and female gender identities, are scarce. Objective: This study aims to estimate the HIV prevalence rate in the Flemish and Brussels (Belgium) transgender population, including transgender women as well as transgender men and non-binary people, and identifying the associated individual and community-level risk factors. Methods: In this community-based cross-sectional study, self-identified transgender and non-binary (TGNB) people will be recruited through a two-stage time-location sampling approach to minimize selection bias. In a first part, community settings in which TGNB people gather will be mapped using qualitative and ethnographic research methods, to reveal how the TGNB community in Flanders and Brussels is structured and to develop an accurate sampling frame. In a second part, to select the respondents, a multistage sampling design is applied involving a stratification based on setting type (healthcare facilities vs outreach events), a selection of clusters by systematic sampling and a simple random selection of TGNB people within each cluster. Participants will complete an electronic self-reported survey to measure sociological, sexual and drug-using behaviors (risk factors) and, at the same time, oral fluid aliquots will be collected and tested for HIV antibodies. Logistic regression models will be used to evaluate risk factors independently associated with HIV infection. Conclusion: To the best of our knowledge, this study will be the first to investigate the HIV prevalence rates and behaviors that increase risk and vulnerability for HIV infection in an accurate representation of the TGNB population in a West European country. The findings of this study will globally serve as a knowledge base for identifying subgroups at risk for becoming infected with HIV within TGNB people and to set up targeted prevention programs on sexual health.

It is only between peak viremia and viral setpoint in natural acute HIV-1 infection that the immune response overwhelms viral replication resulting in a plasma viral load decline. The aim will be to characterize these immune responses, how they develop and their progeny. This will require the need to identify HIV-1 infected individuals before peak viremia and follow them to post viral setpoint. This protocol describes a pilot study to evaluate the feasibility of identifying, enrolling and following acute and early HIV-1 infected individuals from voluntary counselling and testing centres in Masaka, Bukomansimbi, Kalungu, Lwengo, Sembababule and Lyantonde districts.

The purpose of this study is to show that the administration of 400/mg/m2/day of didanosine(ddI) during the meal is bioequivalent to the administration of 240/mg/m2/day of didanosine during fasting, in HIV infected children treated by a ARV combination including ddI
