Active clinical trials for "Immune System Diseases"

Syncope, a frequent reason for emergency room visits and hospitalization, is a symptom of three major etiological entities: cardiac causes, vaso-reflex causes and orthostatic hypotension. The etiological diagnosis is often uncertain and the prognostic assessment orients the outcome of the patient. The vast majority of syncope management costs are related to hospitalizations. Hospitalization in the immediate aftermath of emergency care is justified by a short-term prognosis. The current relevance of hospitalizations and the prognostic assessment of syncope is questioned.

Clinical specimens are required from HIV positive individuals with viremia controlled by antiretroviral therapy to complete process development for a genetically modified autologous T cell product, AGT103-T. The product will be used in a subsequent early stage clinical trial in subjects with chronic HIV disease and viremia suppressed by antiretroviral therapy as the initial step in testing a functional cure for HIV disease. Enrolled participants provide a venous blood specimen (approximately 25mL) to determine their level of HIV-reactive CD4+ T cells. Subjects with positive T cell responses will be asked to undergo leukapheresis and their clinical specimens will be used to validate and qualify the AGT103-T cell product.

Diabetes Mellitus type 1 is characterized by an absolute insulin deficiency caused by T-cell-mediated autoimmune destruction of pancreatic β-cells . It is the predominant form of diabetes mellitus during childhood and adolescence. Hyperglycemia is a major cause of vascular and neuropathic complications that are seen in patients with diabetes mellitus type 1.

This study is a prospective cohort study of children diagnosed with primary immunodeficiency disease (PID). The aim is to investigate the clinical characteristics and prognosis of PID in Chinese children.

To measure the prevalence of Neuropathic pain in Rheumatoid arthritis patients with ankle and foot pain To evaluate the role of Neuromuscular Ultra sound (NMUS) and nerve conduction study (NCS) in assessment of Neuropathic foot and ankle in Rheumatoid arthritis patients

North-east area of France was hit in February 2020 by the new coronavirus disease, more severely than other French regions. Factors affecting the evolution of the disease and its severity have been quickly identified, among them figuring different kinds of immune deficiency. Even if nowadays HIV infection is usually well controlled by ARV drugs, those patients with uncontrolled viral load and/or low CD4 cell counts, remain at higher risk of severe COVID infection. In this context, the primary objective of our study is aimed at evaluating the prevalence of SARS-CoV-2 antibodies in a cohort of HIV-infected patients followed-up in an HIV-infection care center. Secondary objectives are: evaluating whether the antibodies are protective or not, the kinetic of these antibodies, and HIV associated factors with the presence of antibodies.

This study has the aim to analyze intestinal expression of cellular stress molecules in patients with intestinal GVHD. Patients with colitis and patients without intestinal inflammation will serve as controls.

"Physical activity and diet in children and young people with arthritis" A qualitative study of exploring stake holder's experiences. Juvenile Idiopathic Arthritis (JIA) is the most common type of arthritis in children under the age of 16. The disease and its therapeutic management can cause serious long-term complications, which affect general activities and quality of life. The lack of specific guidelines for safe physical activity and appropriate management of any nutritional deficit aiming our study to find out your views and opinions about the needs of children and young people with juvenile idiopathic arthritis. We want to improve our knowledge about the impact of physical activity and eating habit on juvenile idiopathic arthritis and we want to develop a tool to help evaluate care. Few studies targeting quality of life and wellbeing in children adolescent populations have adopted the diet and physical activity perspective or approaches, consequently, this research project will help to address this gap through: Interview: to look at young people's current experiences with JIA as well as their parents/caregivers and health care professionals. Study findings will provide a snapshot of the current experiences of participants, helping to improve our knowledge about JIA, physical activity, and diet. Qualitative studies exploring people perspectives on their experiences, when collected systematically, adds valuable depth, insight and understanding into the issues related to JIA not possible through quantitative methodologies. This study uses a qualitative approach known as framework methodology to understand stakeholder's experience of what helps and what hinders improving the quality of life in children and young adult with JIA. 21-30 stakeholders will be recruited in Oxford UK, to take part in individual semi-structured guided interviews lasting approximately one hour. Participant responses will be transcribed by the chief investigator and analysed to extract themes that will answer the research question. Delphi study: which aims to develop a diet and physical activity intervention for children and young adult with JIA.
