The investigators propose to evaluate Rapid HIV Treatment Initiation in Baltimore in newly and previously diagnosed HIV-positive patients not in care through identification of barriers, facilitators and acceptability of Rapid HIV Treatment Initiation among newly and previously diagnosed HIV-positive patients not in care identified at the Johns Hopkins East Baltimore campus and at the Baltimore City Health Department sexually transmitted disease clinics. Using this data, a protocol for Rapid HIV Treatment Initiation among newly and previously diagnosed HIV-positive patients not in care identified at the Johns Hopkins East Baltimore campus and the Baltimore City Health Department sexually transmitted disease clinics will be developed and pilot tested. This pilot data will be used to design a multi-site study evaluating the effectiveness of Rapid HIV Treatment Initiation versus facilitated linkage to care. A model for Rapid HIV Treatment Initiation in Baltimore could be generalized to cities where the HIV epidemic has a similar demographic and risk profile such as Washington DC, Atlanta, and New York City.
An intervention study was designed to examine the impact of impact of community home-based care intervention on mental health and treatment outcome in HIV-positive people. The intervention comprised a home-based counseling on anti-retroviral therapy (ART) adherence, psycho social support, basic health care services at the home of HIV-positive people. The intervention started in March, 2018 and completed in August 2018. The major measurements of the interventions were ART adherence, status of depression, anxiety, and stress levels.
This study evaluates the efficacy, safety and tolerability of switching from the older, established single tablet regimen of ATRIPLA® (EFV/FTC/TDF) to a new single tablet regimen of BIKTARVY® (BIC/FTC/TAF), in HIV-1 infected adult subjects who are virologically suppressed (HIV-1 RNA<50 copies/mL).
The investigators propose a pilot study using (1) MRI to assess coronary artery endothelial function, (2) brachial ultrasound to assess systemic endothelial function, (3) serum markers of inflammation and of endothelial cell function and (4) echocardiographic measures of left ventricular diastolic and systolic properties, before and following initiation of PCSK9 antibody in HIV positive subjects.
Background: Weight gain can lead to obesity and diabetes even in people living with human immunodeficiency virus (HIV). Researchers want to see if the technique intermittent calorie restriction can help overweight people with HIV as an alternative to traditional diets. Objective: To see if intermittent calorie restriction leads to weight loss and improved blood sugar in obese people with HIV. Eligibility: Adults ages 18-65 with HIV who are obese and do not have diabetes Design: Participants will be screened with a medical history, physical exam, and blood and urine tests. Before starting treatment, participants will: - Have a nutritional consultation - Get a pedometer to record daily steps - Test a restricted diet for 1 day - Have a body x-ray At the baseline visit, participants will have: - Blood drawn after they drink a sugar drink - Questions about their health and eating - A nutritional consultation - Resting energy expenditure measured. Participants will fast overnight. Then they will lie down while a plastic bubble goes over the head and a plastic sheet covers the upper body. Oxygen flows into the bubble. - Liver stiffness test. A wand on the stomach releases sound waves like an ultrasound. For 12 weeks, some participants will be on a standard diet. Others will restrict how much food they eat 2 days a week. On those days they will eat about 25% of their recommended calories. Participants will keep a diary of their diet and steps. Participants will have 4 visits during the 12-week diet and 1 visit 12 weeks after the diet ends. They will repeat previous tests.
This is a single-center, open-label study on safety, tolerability and immunogenicity of Gardasil®9 in 18 to 45 year-old HIV patients, in 18 to 55 year-old solid-organ transplant (SOT) patients. This study will enrol 100 HIV patients with CD4+ count of >200cells/mm² and 170 SOT patients, all of whom have not yet received a prophylactic HPV vaccine. The 170 SOT patients will be equally divided over 3 different SOT patient groups, namely heart, lung and kidney transplant patients. Therefore the target is to include approximately 57 heart transplant patients, 57 lung transplant patients and 57 kidney transplant patients. Enrolment in a SOT subgroup will be stopped when 57 patients have been included unless recruitment cannot be achieved within one of the other SOT-patient population. All enrolled subjects will receive a 3-dose regimen (Day 1, Month 2, and Month 6) of GARDASIL®9. Serum samples will be collected on Day 1 and Month 7 for anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 antibody determination. The time point for comparison of immune responses will be Month 7, or approximately 4 weeks after the administration of the third dose. The safety/tolerability profile of the vaccine will be evaluated in all subjects in the study. Safety information will be collected on Day 1 through 1 month following the third vaccination or for a total of approximately 7 months for each subject. The immunogenicity and the safety data will be analyzed per group of patients. More specifically a separate analysis of HIV and SOT patients is planned, since it is expected that the immunosuppressive therapy of SOT patients might have a more profound effect on immunogenicity following vaccination. This study will provide a comparison of immunogenicity of Gardasil ®9 in immunocompromised patients, with historical controls. The number of subjects to be enrolled in the study was determined based on the primary immunogenicity objective.
The conventional way to control HIV infection is the usage of a drug cocktail capable of suppressing the viral replication cycle, commonly known as antiretroviral therapy (ART). Despite effective ART it is not possible to eradicate HIV. The virus hides in particular cells to form the latent HIV-reservoir.[1-9] Studies that emphasise on revealing hidden reservoirs would aid in designing novel therapeutic strategies for controlling HIV infection. Molecular imaging by SPECT/CT has the potential to reveal hidden reservoirs of HIV virus that are not eliminated by currently used drugs capable of suppressing and thereby controlling the viral replication cycle in HIV infected patients. New approaches, necessary to prevent and treat HIV-1 infection, are gradually emerging. A new generation of highly potent broadly neutralizing antibodies (bN/Abs) may represent a promising approach to combating HIV-1 infection.[10] The broadly neutralizing antibody 3BNC117 antibody that can mimic human CD4 binding targeted against the HIV gp120 envelope protein has been tested in various clinical trials.[11-14] It has found to be safe and effective in reducing viraemia and to improve host humoral responses in HIV-1 infected individuals, and to have effect on viral rebound in patients who are kept off antiretroviral treatment briefly for experimental purpose. Imaging of simian immunodeficiency virus (SIV) infection by PET/CT has been successfully performed in nonhuman primates with a 64Cu-labeled SIV gp120-specific antibody called 7D3.[15] This study aims to use a similar approach in human with the 3BNC117 antibody. The 3BNC117 antibody has been successfully radiolabeled with iodine 123. The half-life of this radioisotope is appropriate for antibody imaging in nuclear medicine. Radiolabeled 123I 3BNC117 was shown to keep a good immunoreactivity for gp120. By using state of the art SPECT scanner a semi-quantitative image will be obtained. In addition, the absence of any chelator and the well known use of iodine-123 in clinic make it suitable for human intervention. No HIV imaging in human has been achieved yet, which is however fundamental to understand some key steps in the pathogenesis of HIV-induced immunodeficiency. This research opens promising opportunities for drug and vaccine development. Indeed, identification of virus reservoirs in treated patients would facilitate the development of strategies for eradicating these reservoirs or for extending latency period.
HIV persists despite antiretroviral therapy (ART) and is associated with chronic inflammation. This inflammation is thought to prevent an effective immune response against the virus and is mediated at least in part by gut epithelial permeability and microbial translocation. HIV accumulates preferentially within Th17 cells with time on ART; these memory CD4+ T cells are highly susceptible to HIV infection and are concentrated within the gut. Vitamin D promotes gut epithelial integrity in animal models and exerts anti-inflammatory effects on the human immune system including down-modulation of Th17 cell frequency. This study will evaluate whether high dose vitamin D is able to reduce immune activation and Th17 cell frequency, to improve gut barrier integrity and the gut microbiome and reduce HIV persistence in participants on long-term suppressive ART.
This is a randomised two-part Phase I study which will explore the impact of different boosting options (MVA-CN54 and recombinant CN54gp140 protein) for oral Adenovirus serotype 4 vector prime expressing HIV-1 CN54 envelope (Ad4-EnvCN54) designed to optimize systemic and mucosal antibody responses. Part 1 is exploratory and designed to select conditions capable of promoting enhanced systemic and mucosal B cell responses in a limited number of participants. Part 2 is dependent upon Part 1 and is designed to study groups selected on performance in part 1 in an expanded number of subjects. Data from both stages will be combined for safety and immunological analyses.
