Filter by:Juvenile idiopathic arthritis (JIA) is a chronic disease characterized by persistent joint inflammation. The immune system disruption that leads to overproduction of pro-inflammatory cytokines (TNF-α, IL-1, IL-6) is a cascade of events on different levels—some molecular, some cellular, and some systemic. Our objective is to identify the mechanisms through which physical activity is liable to mediate inflammatory balance in autoimmune disease settings, and specifically in JIA patients.
This is an open-label randomized controlled trial to compare the efficacy of Prednisone alone and combination therapy of Prednisone and Mycophenolate mofetil in IgG4RD patients.
Psychosis is a mental health problem that causes people to perceive or interpret things differently from those around them, often involving hallucinations or delusions. Psychosis and schizophrenia are common disorders which predominantly affect younger adults. Recently, the investigators discovered that 5-10% of people with psychosis have antibodies in the blood that are capable of targeting the surface of brain cells, specific to the N-methyl-D-aspartate (NMDA) receptor or voltage gated potassium channel complex, which the investigators believe may be causing the problem. Those positive for antibodies may have a problem with their immune system and this may prevent their brain from working normally. This trial aims to test the feasibility of removing or reducing the antibodies in patients' blood, using immunotherapy, and see if this improves symptoms of psychosis. Immunotherapy in this feasibility study will involve giving all patients steroid tablets and half of them will also receive a drug called "intravenous immunoglobulin" whereas the other half will have a procedure called "plasma exchange". The feasibility study is designed to identify which method of immunotherapy is most suitable for use in this patient population. Results from this will inform on the methodology used for a proposed larger randomised control trial.
The purpose of this study is to assess the diagnostic utility of Sudoscan in assessing small fiber nerve function, specifically those of the sudomotor, in patients with autoimmune disorders (i.e fibromyalgia and rheumatoid arthritis).
The purpose of this study is to compare immune phenotype, function, and specificity of B lymphocytes from different developmental stages in autoimmune patients to B cells from infectious disease patients and healthy controls.
This study plans to learn more about Down syndrome. The investigators think there is a different level of the AIRE gene in individuals with Down syndrome. The investigators think that the AIRE gene level can provide more insight about depressed immune cell function in individuals with Down syndrome. Patients are being asked to be in this research study because the investigators want to see if their blood contains more of less of the AIRE gene.
Inflammatory cytokines play a pivotal role in rheumatoid arthritis (RA) and innovative non-pharmacological therapies aimed at limiting cytokine production are highly warranted. Adrenaline, a neurotransmitter of the autonomic sympathetic nervous system, attenuates cytokine production. Along these lines, endogenous modulation of sympathetic activity could limit inflammation and therefore represent a treatment modality that would empower RA patients to exert self-control over disease activity. However, both the autonomic nervous system and the inflammatory response are regarded as systems that cannot be voluntarily influenced. Nevertheless, results from two recent studies demonstrate that this is possible through techniques developed by 'iceman' Wim Hof, namely meditation, exposure to cold, and breathing exercises. Hof himself and healthy volunteers trained by him were able to voluntarily activate the sympathetic nervous system, resulting in adrenaline release and subsequent suppression of the inflammatory response during experimental human endotoxemia (a model of systemic inflammation elicited by administration of lipopolysaccharide [LPS] in healthy volunteers). Interestingly, while having been taught all three techniques, during the endotoxemia experiment the trained subjects (like Hof himself) predominantly practiced the breathing exercises consisting of two different techniques. A `hyper/hypoventilation` technique, characterized by cycles of hyperventilation followed by breath retention and a `strength ventilation` technique consisting of deep inhalations and exhalations followed by breath holding. These techniques resulted in intermittent hypoxia and cyclic shifts in acid-base balance. Based on these observations and previous studies, the investigators hypothesize that these breathing techniques account for the increased production of adrenaline and thus for the suppressed inflammatory response but it is unclear which of these two techniques is most important.
Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune-mediated disorder of peripheral nerves. Intravenous immunoglobulins (IVIg) are a first line therapy for CIDP. The investigators used a transcriptomic approach to compare the gene expression profiles in the peripheral blood of patients having a CIDP or autoimmune diseases, before and after IVIg treatment, in order to identify their mechanism of action in this condition, to lead to a better understanding of CIDP pathophysiology, and potentially determine factors associated with the response to the treatment.
GSK2618960 is a humanized Immunoglobulin G 1 ( IgG1) monoclonal antibody (mAb) that binds to the alpha component (CD127) of the heterodimeric Interleukin-7 receptor (IL-7R). It is being developed for the treatment of autoimmune indications. This study is intended to further explore the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and immunogenicity of single ascending doses GSK2618960 in healthy volunteers beyond those already evaluated in I7R116702 (First Time In Human study). The study is anticipated to enrol 18 subjects in total, with 9 subjects in each of the two cohorts.
This study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of CBP-307 following oral single and multiple escalating dose administration in healthy subjects.
