View clinical trials related to Immune System Diseases.
Filter by:Background: Immune system and nervous system have significant interaction so that People with immunity diseases can have complications that affect the nervous system and people with some neurological disease may have defects in their immune system.These complications can affect many body functions, including how they move, walk, think, and feel. Researchers do not fully understand how immune diseases affect the nervous system. By learning more, they hope to create more effective treatments. Objective: To learn more about the interaction between immune and nervous system and how immunity disease affect the nervous system. Eligibility: People aged 2 years and older with an immunity disease. Their healthy biological relatives and other healthy volunteers are also needed. Design: Participants will be screened. Blood will be drawn for research. They may have imaging scans. Adults may undergo lumbar puncture: A needle will be inserted into their back to collect fluid from the space around the spinal cord. The imaging scans and lumbar puncture will be optional for healthy relatives and volunteers. All participants will have 1 study visit per year for 5 years. They will be asked to donate samples of body fluids at each visit. Blood samples are required for the study. All other donations are optional. These may include saliva, urine, breast milk, stool, vaginal secretions, and wound drainage. Affected participants may be asked for a skin biopsy: A small sample of skin will be removed. They may also be photographed or videotaped to record the symptoms of their disease. Tests for each study visit may be spread over several days, if needed. Visits may be at the clinic. Participants may also collect their own samples at home and send them to the researchers....
The pandemic associated with the SARS-CoV-2 coronavirus has affected over 760 million individuals worldwide, resulting in more than 6.9 million deaths. France has also been heavily impacted, with over 39.8 million infections and 167,000 deaths. SARS-CoV-2 primarily causes an upper respiratory tract infection transmitted through the air. When it reaches the lungs, it leads to a severe acute respiratory illness called COVID-19. The body's response to this viral assault primarily occurs at the level of the respiratory mucosa. This mucosal response is complex, involving various levels of activity. Mucosal immunity is therefore essential for an adequate and long-term immune response against viral respiratory infections, including SARS-CoV-2 infection. Infection with SARS-CoV-2 triggers a humoral immune response with the production of antibodies in the blood (serum antibodies) and antibodies in the upper respiratory tract (mucosal antibodies). It also induces a cellular immune response by activating specific blood T lymphocytes. Tests used to measure the humoral blood response against SARS-CoV-2 and their neutralizing capacity are now well identified, as are tests for assessing the serum cellular T lymphocyte response. However, tests for measuring mucosal immune responses are not routinely used. Our study aims to develop and qualify methods for analyzing mucosal immunity directed against SARS-CoV-2. These methods will be essential for a more precise analysis of the body's mucosal response to this virus. Once these analytical methods are validated, they will enable the study of mucosal responses to infection, as well as mucosal responses induced by vaccination against SARS-CoV-2, particularly in the context of future nasal vaccine use.
Aerobic exercises can produce immediate and short-term improvements in the immune response of leukocytes, T-lymphocytes, lymphocyte subpopulations, interleukins, and immunoglobulins. Even only a single session of aerobic exercises produces improvements in the utmost immune markers, such as T-lymphocytes, leukocytes, and immunoglobulins. Also, burned patients suffer from post-traumatic stress and stress can cause this alteration through its effect on increasing the amounts of serum corticosteroid and catecholamine hormones, thus a decrease in the immunity response might occur. Increasing the aerobic capacity can significantly improve the mood. This might be attributed to the effect of aerobic exercises on decreasing stress hormones, like corticosteroids and catecholamines hormones. The altered metabolism post major burn also affects the immune system in burn patients and the aerobic training enhances the metabolism, body composition and the lean mass and so, enhances the immune system. One of the most important factors for a good and effective immune system is the balanced diet especially diet rich in vitamin D, fibers, and multiple nuts and seeds such as almond, walnut, pistachio, sunflower seeds, flax seeds and sesame seed that have an crucial role in improving the immune system either acting on it directly or indirectly by enhancing the general heath of the body and the patients mood.
The study started after the second COVID-19 vaccination of the participant with blood spots appearing on the skin with severe arthritis. The study continued to the third-dose full vaccination of the participant with the recombined COVID-19 vaccination and afterwards. The study completed until intervention.
The investigators will study the mechanistic details of dietary programming of the epigenome at the example of epigenetic programming of primary human immune cells with the micronutrient vitamin D3. They will follow a small number of healthy adult volunteers individually over time while measuring per individual a large number of molecular and dynamic parameters that will be used for mechanistic modeling. The main hypothesis of the investigators is that nutritional components, such as vitamin D3, have a direct effect on the epigenome of the different cell types of the immune system. Using complementary in vivo, in vitro and in silico approaches, they will investigate the mechanistic basis of this dietary epigenetic programming process and how it creates memory.
The investigators will conduct a trial to evaluate if an online training and support platform can help adults living with type 1 diabetes (T1D) in their diabetes self-management. Investigators will compare a group that has access to the "Support" platform through their usual medical care to a group that accesses the platform independently. The first group will be recruited through four participating clinics in the province of Quebec (Canada). The second group will be composed of adults living with T1D across Canada. Participants will have access to the platform for 12 months and will be asked to complete online questionnaires at the beginning and after 6 and 12 months, and share their glucose reader data with the research team. A subgroup of participants as well as healthcare professionals from the four clinics will be invited to participate in an individual interview aiming to understand the barriers and facilitators of integration "Support" in clinical care.
This study aims to assess biomarkers and their related polymorphisms in the context of cancer-associated thromboembolism, with a particular focus on their interaction with the immune system. The roles of immune checkpoints, inflammatory and angiogenesis factors, as well as circulating immune cells will be elucidated. Additionally, our investigation extends to the exploration of long non-coding RNAs (LncRNAs) and genes associated with the coagulation vascular system. Initially, these aspects will be evaluated in the context of colorectal cancer, with the intention to expand our research to other solid tumors. The identification of these biomarkers and genetic factors holds the potential to revolutionize therapeutic approaches for patients with cancer-associated thromboembolism, shedding light on their chemotherapy resistance. The effectiveness of combining immunotherapy with targeted inhibitors like Palbociclib and anticoagulants such as Rivaroxaban, among other potential interventions, will be assessed. This study aims to make significant contributions to the understanding of these critical aspects, ultimately leading to the development of more effective treatment strategies for cancer patients.
The goal of this clinical trial is to explore the role of wheat and corn germ blended oils in regulating oxidative stress and immunomodulation in dyslipidaemic populations, to explore their effects on intestinal flora, antioxidant and immunomodulation. The main questions it aims to answer are: - How does phytosterol-rich wheat corn germ blended oil affect oxidative stress and immune function in dyslipidaemic people compared to peanut oil? - How does phytosterol-rich wheat corn germ blended oil affect serum metabolites, serum fatty acid profile, and intestinal flora in dyslipidaemic populations compared to peanut oil? What are the specific mechanisms involved? Participants will be randomly assigned to the intervention and control groups, the packaging of germ oil and peanut oil will have a uniform appearance, and participants will be instructed to replace their household cooking oils with the distributed cooking oil for three months, in addition to replacing all the canteens in the staff units with the trial oil for more than three months. Participants did not know who was the control oil, germ oil or peanut oil, and both were randomly distributed to different groups of participants by the third-party supervisors. Researchers will compare peanut oil to see if phytosterol-rich germ oil can improve oxidative stress and immune function in dyslipidaemic populations, in addition to exploring possible underlying mechanisms of improvement using multi-omics techniques.
