Filter by:The investigators seek to understand how the different underlying causes of OSA affect the way people living with HIV (PLWH) experience OSA. The investigators also want to understand how symptoms of obstructive sleep apnea improve with treatment, and if this too, is affected by the underlying cause of OSA in that individual
The primary purpose of the study is to evaluate the efficacy of rilpivirine (RPV)-based regimen in human immunodeficiency virus type 1 (HIV-1) infected, antiretroviral (ARV) treatment-naive participants, as determined by the percentage of virologic responders defined as having HIV-1 ribonucleic acid (RNA) less than 400 copies/ milliliter (mL) at Week 24.
Aging populations experience a decline in adaptive immune system function also known as immunosenesence. Nutritional approaches to stimulate and strengthen the immune system are needed for this growing segment of the population. A controlled, randomized, double blind pilot study was conducted using two different protein sources as nutritional supplementation to enhance vaccine response. Our objective was to examine the immune stimulating effects of dairy protein subjected to ultraviolet radiation (UV-C) radiation treatment process instead of pasteurization. Participants were 21 healthy individuals over 60 years of age who consumed 6 g of the dairy protein or a comparison, soy isoflavone protein, twice a day for eight weeks. DTaP vaccine administered at week 4. Non-parametric t-tests revealed a significant increase in Tetanus antibodies in the dairy group compared to the soy group at week 8. These findings suggest additional benefits of UV-C treated unheated dairy protein as a solution to counteract immunosenescence, but warrant further study in elderly and other populations that might benefit from immune system stimulation.
The main objective is to offer diagnostic tests for HIV, HCV and other STD in the risk group of men having sex with men (MSM) users of Chemsex
This study aims to determine if a new method can be used to treat Artemis-deficient Severe Combined Immunodeficiency (ART-SCID), a severe form of primary immunodeficiency caused by mutations in the DCLRE1C gene. This method involves transferring a normal copy of the DCLRE1C gene into stem cells of an affected patient. Participants will receive an infusion of stem cells transduced with a self-inactivating lentiviral vector that contains a normal copy of the DCLRE1C gene. Prior to the infusion they will receive sub-ablative, dose-targeted busulfan conditioning. The study will investigate if the procedure is safe, whether it can be done according to the methods described in the protocol, and whether the procedure will provide a normal immune system for the patient. A total of 25 patients will be enrolled at the University of California San Francisco in this single-site trial, and will be followed for 15 years post-infusion. It is hoped that this type of gene transfer may offer improved outcomes for ART-SCID patients who lack a brother or sister who can be used as a donor for stem cell transplantation or who have failed to develop a functioning immune system after a previous stem cell transplant.
Endothelial dysfunction and insulin resistance play a key role in the onset and development of atherosclerosis, cardiovascular diseases, and diabetes. Data in mice models have recently demonstrated that circulating immunoglobulins G (IgG) could be involved in the process. Patients with common variable immunodeficiency (CVID), who are characterized by low circulating levels of IgG, might represent an ideal model to clarify the role played in vivo in humans by circulating IgG. Polyclonal IgG, obtained from multiple donors, given intravenously (IVIgG), are used to treat various immunodeficiencies and autoimmune diseases, including CVID. By using this disease and its treatment by IVIgG as a model, aim of the current study is to clarify whether IgG affect endothelial function and insulin sensitivity in humans in vivo and whether the action of IgG on the endothelium involves a direct interaction with the endothelial cells.
The purpose of this study is to test the effectiveness and implementation of a brief, integrated behavioral intervention for HIV medication adherence and substance use in the HIV care setting in South Africa. The intervention is specifically designed to be implemented by non-specialist counselors using a task sharing model in local HIV clinics. The behavioral intervention will be compared to usual care, enhanced with referral to a local outpatient substance use treatment program (Enhanced Standard of Care - ESOC) on study endpoints (as described in study endpoint section below).
This study will address the following hypothesis: Rituximab therapy leads to an acquired immune deficiency, as demonstrated by impaired vaccine responses, in AAV patients. Aims: 1. To investigate whether rituximab leads to immune deficiency in patients with AAV when compared to both disease and healthy controls. 2. To investigate whether the degree of immune deficiency is associated with the degree of B cell depletion. 3. To investigate whether T-independent vaccine responses are more severely affected than T-dependent vaccine responses after rituximab and whether a conjugated vaccine will overcome this postulated deficit in T independent vaccine responses.
In this study, the investigators test 2 dose levels of thiotepa (5 mg/kg and 10 mg/kg) added to the backbone of targeted reduced dose IV busulfan, fludarabine and rabbit anti-thymocyte globulin (rATG) to determine the minimum effective dose required for reliable engraftment for subjects undergoing hematopoietic stem cell transplantation for non-malignant disease.
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.
