Filter by:Antiretroviral therapy of the mother and of the newborn associated with alternative schemes of breastfeeding can reduce these transmission rates to 1%. The diagnosis of HIV infection in newborns is based on PCR for detection of viral genetic material, a procedure that is expensive and of complex logistics. Tests based on detection of antibodies are faster and cheaper but cannot distinguish infected child or maternal antibodies passed to the fetus through the placenta. Nevertheless, the so-called rapid tests have been implemented in the network of health services because of their simplicity and performance comparable to conventional tests. DPP HIV 1/2 test, produced by Bio-Manguinos/Fiocruz, usage is limited by the manufacturer to over 24 months of age children, though the guidelines control programs already recommend the use from 18 months in Brazil and 9 months in other countries. Data on the accuracy of the rapid test under 24 months of age are scarce. This proposal aims to assess the performance of rapid tests produced by Bio-Manguinhos in diagnostic protocols for HIV infection in children 9-24 months old, in order to obtain empirical data to support the current recommendations on rapid tests, particularly in countries with limited access to tests that require specialized laboratories. The validation of rapid HIV testing in other age groups is a requirement of the national regulatory authorities, and has important implications for programs to control HIV-AIDS in populations from countries with limited access to specialized laboratory resources. The use of the rapid test can also represent a significant reduction in costs, as it allows limiting the use of molecular tests to complex and expensive confirmation cases.
This will be a two-arm cluster randomized controlled trial. The control group can share their Center for Disease Control and Prevention certified online HIV results (COHIV) with another party freely through a social networking tool, while the intervention group will be asked for the COHIV before he can see the COHIV of his friend. The investigators hypothesize that the requires exchange will promote HIV testing and thus reduce HIV incidence among MSM.
To evaluate the safety and efficacy of arsenic trioxide combined with cART in eliminating latent HIV-1 reservoir, providing potential strategies for AIDS functional cure.
Many persons living with HIV/AIDS (PLWHA) are unemployed, with estimates indicating rates as high as 60%. This study will examine the efficacy of reinforcing job-acquisition activities for improving employment outcomes in PLWHA who desire to return to the workforce in part- or full-time capacity. In total, this study will randomly assign 144 unemployed PLWHA to one of two interventions. All participants will receive usual unemployment services with an emphasis on specific issues related to HIV/AIDS, plus encouragement for completing activities geared toward employment readiness and acquisition. The enhanced intervention will involve that same treatment plus chances to win prizes for engaging in job-related activities each week. Participants will receive study treatments for 16 weeks and complete follow-up evaluations throughout 18 months. The hypothesis is that participants reinforced for completing job-related activities will transition to employment at higher and faster rates and work more often than those who are not reinforced for job-related activities.
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
To evaluate effectiveness of voluntary assisted partner notification (VAPN) in real-world programmatic settings, a non-randomized, stepped wedge study in high volume facilities in 6 high HIV burden focus districts (Blantyre, Zomba, Chikwawa, Machinga, Mangochi and Lilongwe urban) is proposed. The primary objective is to compare the percentage of contacts tested during the standard of care (SOC) phase (i.e., using passive family referral services (FRS) index testing methodology) with the percentage of contacts tested during the SOC plus VAPN phase, by 1, 2, and 3 months after the initial contact with the index client. Assessment of feasibility will be achieved through documentation of operational lessons learned during implementation. Findings will contribute to ongoing policy discussions whether Malawi should adopt VAPN in its national HIV testing guidelines
The project will study a European cohort of individuals identifying themselves as transgender or non-binary and living with HIV. The study will collect both qualitative data on this cohort and clinical data over an 18 month period. The study will investigate the success of HIV treatment for this cohort through the primary outcome measure of HIV viral load recorded in routine blood tests. The results from this study will assist in informing future HIV treatment guidelines on the monitoring of HIV infection in transgender and non-binary individuals and assisting in the design of future interventional studies within this population.
The principal objective is to define and compare the viral reservoir, mucosal immune responses and the microbiota of different HIV infection stages; viremic, aviremic (under treatment), natural elite controllers; The secondary objective is to compare the mucosal immune response and microbiota of HIV patients with the healthy control population of Milieu Interieur;
Smokers living with HIV represent a major health disparity population in the United States and the world more generally. Major contributing factors to the maintenance and relapse of smoking among smokers living with HIV include increased exposure to multiple stressors associated with HIV, which often exacerbates anxiety/depression. In a previous project, the feasibility, acceptability, and initial efficacy of a 9-session, cognitive-behavioral-based intervention to address smoking cessation by reducing anxiety and depression via specific emotional vulnerabilities (anxiety sensitivity, distress tolerance, and anhedonia) was tested against an enhanced standard of care in a pilot randomized controlled trial (NCT01393301). It was found that when compared to a brief enhanced treatment as usual control, patients in the intervention achieved higher short-term and long-term smoking abstinence rates. In this project, the investigators seek to test this same intervention in a fully powered, 3-arm efficacy/effectiveness trial. The goal of this study is to randomize 180 smokers across three sites to test the efficacy/effectiveness of the intervention at increasing point prevalence abstinence by reducing anxiety and depression at a 1-month follow-up (the end of treatment timepoint/ approximately 1-month post quit day) and a 6-month follow-up (approximately 6-months post quit day).
Dolutegravir (DTG) is one type of integrase inhibitor, lamivudine (3TC) is one type of reverse transcriptase inhibitor, both of which are HIV medicine prevents HIV from self-multiplying, reduces the viral load. The data of the existing randomized controlled clinical studies show that the simplified two-drug DTG-based regimen is similar to the three-drug regimen in terms of efficacy, but there are no relevant data and reports on the efficacy and safety of DTG+3TC in HIV-infected patients in China so far. This project aims to explore the efficacy and safety of the DTG + 3TC regimen for HIV-infected patients in real clinical environment, to guide clinical application, and to provide a theoretical basis for the selection of simplified schemes for the formulation of guidelines. This study was done to see if the combination of two anti-HIV medicines, dolutegravir (DTG, Tivicay) and lamivudine (3TC, Epivir) taken once a day, provide a safe, effective, and well-tolerated treatment for HIV.
