Active clinical trials for "Immunologic Deficiency Syndromes"

The study harnessed the multidisciplinary expertise of our research team to develop a brief, computer-based, alcohol reduction intervention tailored for HIV/HCV co-infected women and evaluate its efficacy. The intervention, if effective, may be an efficient and cost-effective alcohol reduction strategy, that is scalable and can be readily disseminated and integrated in clinical care at other AIDS Centres in Russia to enhance women's health and reduce HIV/HCV transmission risk.

Oral pre-exposure prophylaxis (PrEP) has been proven effective in reducing HIV infection in high-risk men who have sex with men, heterosexually active women and men, and injecting drug users. Despite its 2012 approval by the FDA and the development of Centers for Disease Control and Prevention (CDC) clinical guidelines, PrEP uptake has been limited. Significant impediments to PrEP implementation include: system barriers (lack of a medical "home" and of models for implementing PrEP); provider barriers (difficulty identifying those likely to benefit from PrEP, inexperience with PrEP, and concerns about adherence and risk compensation); and user barriers (lack of awareness of PrEP, inability to access providers comfortable with prescribing PrEP, and concerns about stigma and side effects). Cost is not a barrier in New York State, where PrEP is covered by many insurance plans, including Medicaid. Primary Care for PrEP (PC4PrEP) is a structural, multilevel intervention that will integrate PrEP into primary care practices that care for underserved communities in the Bronx, NY, an epicenter of continuing HIV infection in the US. PC4PrEP will develop an organizational protocol for prescribing PrEP in primary care; identify high-risk individuals in primary care clinics and community HIV testing sites using a new PrEP Eligibility Tool; link them to primary care providers (PCPs) who can provide PrEP; and counsel potential users about PrEP both before they receive a prescription (to enhance receptivity), and after they initiate PrEP (to enhance adherence). In the course of this study, investigator(s) will (1) develop and pilot PC4PrEP; (2) implement and evaluate it in "real-world" settings (Federally Qualified Health Centers; FQHCs) on objective outcomes as well as provider and patient reports; and (3) present a new model, the PrEP Cascade that - as with the HIV Care Cascade for HIV+ populations - may be used to evaluate the impact of PrEP programs in the US and other countries. PC4PrEP is consistent with CDC and New York State Department of Health (NYSDOH) Guidelines and the Affordable Care Act in integrating PrEP into primary care practices and is responsive to recent 2014 NYSDOH recommendations which now position PrEP as a first-line intervention for MSM and transgender women who engage in ongoing anal sex without condoms, HIV- partners in sero-discordant relationships, and high-risk heterosexual women in high seroprevalence areas.There are two Specific Aims: (1) Finalize the PC4PrEP intervention and, in a clinic-randomized Phase 2 futility trial, assess whether it shows promise for increasing PrEP prescription rates in the Bronx, NY; and (2) Identify strengths and limitations of PC4PrEP in two ways: (a) through a mixed-methods process evaluation PrEP-eligible patients and PCPs, counselors and navigators; and (b) by identifying "fall-off" at each step of the PrEP Cascade.

The purpose of the study is to assess the ability to swallow the Darunavir/Cobicistat (DRV/COBI) fixed dosed combination (FDC) tablet dispersed in water.

The main objective of the study is to determine the pharmacokinetics profile of Subgam-VF. The secondary objectives are to assess the safety of Subgam-VF and refine the dose adjustment coefficient for Subgam-VF needed for subjects switching from prior intravenous immunoglobulin (IGIV) therapy.

Objective: To evaluate the relative bioavailability of a new formulation containing a combination of emtricitabine 200 mg and tenofovir disoproxil fumarate 300 mg (T) and compare this formulation with the branded formulation (R) to meet regulatory criteria for marketing the test product in Argentina.

Influenza ('flu) can cause severe infections, especially in people with weakened immune systems such as those with HIV. For this reason, yearly vaccination is recommended with the standard 'inactivated' influenza vaccine to try and prevent infections in these populations. It is also recommended in all health care workers, to help prevent the spread of influenza within healthcare settings. However, having HIV infection may mean vaccines work less well in some people and the investigators do not completely understand why. An alternative to the standard 'inactivated' annual influenza vaccine is the 'live attenuated influenza vaccine' (LAIV), which means it consists of weakened versions of the influenza virus. Unlike the standard vaccine, which is given by injection, LAIV is a spray that is given into each nostril. It is now given to children in the UK in preference to the standard vaccine as it results in greater protection from influenza. In some other countries, like the USA, adults are also given LAIV, where it seems to work just as well as the standard vaccine. A few studies in the past have shown that LAIV is safe and effective in HIVinfected children and adults. The investigators want to give LAIV to HIVinfected and HIV negative individuals, to try to find out new information about how HIV infection may change the way in which people respond to vaccines. The investigators will do this by comparing both the early genetic response to the vaccines and later responses from cells specifically targeted to fight influenza ('Tcells'), in these groups. In the long term, the investigators hope that this will lead to designing new ways of improving the response to vaccines in HIVinfected people. As LAIV is given into each nostril, rather than an injection, the investigators also want to see if LAIV results in Tcells in the lung that are specifically targeted to fight influenza

The overall aim of this study is to reduce risk behaviors and increase health and behavioral health service utilization among disadvantaged, drug-using rural women at high risk for HIV and HCV. This project has potential to make a significant contribution to science by providing knowledge about the health, risk behaviors, and service utilization of a vulnerable and understudied group of women during a time of emerging and significant public health risk in a rural Appalachian setting. Successful completion of the aims of this project will advance the delivery of a low-cost, potentially high impact intervention with implications for a number of other real world settings (such as criminal justice venues) where other disadvantaged high-risk drug users can be identified and targeted for intervention.

The immune system response needs to be forceful but also balanced for a rapid recovery from infection which avoids harmful overreactions. Innate immunity can adapt and respond more efficiently to secondary exposures, thanks to epigenetic and metabolic reprogramming, namely "trained immunity". ABBC1 is a combination of beta-1,3/1,6-glucan with inactivated Saccharomyces cerevisae rich in selenium and zinc for training immunity. ABBC1 includes repurposed synergistic yeast-based ingredients: a unique ß-1,3/1,6-glucan complex and a consortium of probiotic Saccharomyces cerevisiae, rich in Selenium and Zinc. ABBC1 induces trained immunity due to its specific chemical and tridimensional structure: its ß-glucan complex interacts with specific receptors in immune cells, provoking a release of cytokines and priming phagocytosis. Simultaneous activation of these pathways activates innate immunity and counteracts cytokine storm. ABBC1 provides highly bioavailable selenium and zinc, micronutrients with a critical role in an optimal immune responsiveness to allergy, infection, and vaccines. ABBC1 possesses proven microbiome modulating properties, which revert in immune training. Due to its high tolerance, safety and immediate availability, ABBC1 is an ideal candidate for complementary management of geriatric patients with seasonal influenza viruses or COVID-19, or to improve the immune response in the general population receiving the influenza or Covid-19 vaccines. The absence of drug interactions in ABBC1 allows a dosage that is fully compatible with the medication prescribed for all types of patients, including the elderly who are frequently polymedicated, and allows adding an additional therapeutic tool in the fight against the pandemic. This study assesses the benefits of a nutritional supplementation with ABBC1 in volunteers receiving the influenza vaccine during autumn 2020 and the Covid-10 vaccine during winter 2021.
