Filter by:Some individuals are able to spontaneously control HIV replication, the so-called 'elite controllers' (ECs). ECs are crucial for our understanding of HIV infection. While there is more and more evidence pointing towards a role of the innate immune system in elite control, no research has been performed on the role of innate trained immunity in elite control of HIV. In this cross-sectional case-control study, we will study this role of trained immunity in HIV elite control by comparing ECs both to a non-HIV-infected first-degree relative, and to HIV patients who are not elite controllers. In addition, we will study whether HIV itself can induce a trained innate immunity phenotype.
The study is looking at a new way to reduce the risk of catching HIV. Post-exposure Prophylaxis for sexual exposure (PEPSE) is where a month of HIV drugs can be given to reduce the chance of getting HIV, after a risk. To improve its use the Investigators want to see whether providing a 5-day course of PEPSE for people to keep at home (HOME PEPSE) will lead to it being taken much quicker than having to get it from sexual health clinics or A&E. The HOME PEPSE packs contain HIV tablets that are used in routine HIV care. However the type of HIV drugs are slightly different to those currently used in PEPSE and the Investigators hope that they will have fewer side effects. HOME PEP consists of Truvada and Maraviroc. 140 gay men who are at high risk of getting HIV will be randomised to one of two groups. Group A will receive HOME PEPSE immediately and group B will receive HOME PEPSE after 48 weeks on the study.
The purpose of this study is to evaluate the safety and efficacy of Zadaxin® in the treatment of HIV-positive patients with immune reconstitution disorders. Researchers previously used Zadaxin® (Thymosin α-1, Tα1) as an immune adjuvant for people infected with HIV-1 and found that Tα1 and Interferon-α (IFN-α) have a synergistic effect in immune enhancement. In addition, studies have found that the triple combination of Tα1, IFN-α and Zidovudine has better tolerability, safety and efficacy. After treatment, patients have lower HIV RNA and more stable high CD4+ T cell counts. In addition, extensive studies on the administration of Tα1 in thymectomized mice have demonstrated its ability to promote immune reconstitution. The researchers hypothesized that Zadaxin® has a better therapeutic effect on HIV-positive patients with immune reconstitution disorders, can increase the CD4+T cell count, reduce the viral load, and has better safety.
This study will investigate changes in insulin sensitivity, lipid metabolism and endocrine profile in HIV-negative subjects exposed to Biktarvy (B/F/TAF) compared to subject not exposed to B/F/TAF for 28 days.
In 2014, the Joint United Nations Program on HIV/AIDS (UNAIDS) issued treatment goals for Human Immunodeficiency Virus (HIV), the 90-90-90 target. It is important to track success results at each stage of the HIV continuum of care to evaluate progress towards the 90-90-90 target. Although ART can suppress HIV-1 infection to undetectable levels of plasma viremia, HIV DNA integrate and persist in resting CD4+ T cells. Most of the HIV DNA in these cells is defective and cannot cause infection. However, latent HIV-1 genomes that encode replication-competent virus can resurface once ART is discontinued. This latent reservoir is believed to be the largest impediment to a cure by ART alone. There is need for expansion of research examining HIV latency in the context of sustained viral suppression with an eye towards developing a possible cure regimen that could be used on a large scale. To date, there have been no systematic studies to quantify the latent reservoir in virally suppressed HIV-infected patients in Africa. Detecting how much of the inducible virus is left in the human body after ART poses the greatest challenge to fully curing HIV. This study is designed to enroll 222 virally suppressed HIV infected men and women, who will be prospectively followed to document antiviral cocktail, viral suppression and incidences of rebound, measure the size of the latent HIV reservoir and examine the immunological correlates of the latent reservoir. Data generated through this study will provide a clear framework for high-burden countries to reduce gaps at each stage of the HIV continuum of care, maximize linkage, retention and health outcomes.
The postpartum PrEP study (PPS) seeks to evaluate how best to improve adherence to PrEP in postpartum women and to evaluate how acceptable it is to offer HIV self tests for the participant and partner, and provide enhanced adherence biofeedback following a urine test of recent PrEP use (measuring tenofovir). The primary outcome is recent PrEP adherence following the intervention. The secondary outcome is HIV testing uptake in participants' partners.
Objective. To study the impact of V106I mutation in the reverse transcriptase of HIV-1 on the activity of Doravirine. Clinical hypotheses. Doravirine shows a unique resistance pattern with a higher genetic barrier to resistance than other NNRTIs. In contrast to K103N or E138A, the prevalence of single mutations and/or combination of mutations against Doravirine is low. However, in a recent survey conducted in Spain the study investigators have found a V106Iprevalence similar to K103N and E138A. There is a clear need to understand the real impact of this mutation on Doravirine resistance.
Combination antiretroviral therapy (cART) HIV treatments are associated with increased quality of life, and a normalisation of life expectancy in people living with HIV. However, long-term use of cART can lead to side-effects through exposure to drug-related toxicity. For this reason researchers are interested in looking at alternative therapies that might expose patients to fewer and less severe side effects while providing the same quality of care as antiretroviral therapies most often used to treat HIV. The purpose of this study is to investigate if the study drug combination that is being tested (doravirine + dolutegravir) is safe compared with other triple cART regimens.
A prospective non-interventional cohort study at Erasmus MC of adult chronic HIV infected patients of ≥18 years of age who initiate antiretroviral therapy in routine care.
The hypothesize that DTG/3TC will be non-inferior to BIC/FTC/TAF with a 4% margin in virologically suppressed HIV-infected patients. The study will allow claiming for Superiority. Assuming that both DTG and BIC may lead to similar weight gains (approximately 1 kg after 48 weeks) in virologically suppressed HIV-infected patients and that TAF may induce a further weight gain (approximately 1 kg after 48 weeks), also hypothesize that switching to BIC/FTC/TAF may lead to greater weight gain than switching to DTG/3TC over 48 weeks. This trial is a Phase IV, open-label, randomized multicentre clinical trial evaluating the efficacy of DTG/3TC versus BIC/FTC/TAF for the maintenance of virological suppression in HIV patients.
