Filter by:Immunoglobulin A vasculitis (IgA-V), formerly called Henoch-Schönlein purpura, is an immune vasculitis. Relapses are frequent (30%) and most of the time cutaneous (90%). Cutaneous involvement in adults is more severe (haemorrhagic blister or necrotic skin lesions) and more extensive than in children. Quality of life can be significantly altered by frequent cutaneous relapses. Colchicine, historically used for gout flares, is known to be an " old " low cost drug inducing very few adverse events. This molecule inhibits polymorphonuclear cell-chemotaxis to the site of inflammation explaining colchicine clinical efficacy in diseases such as Familial Mediterranean Fever or Behçet disease. Efficacy of colchicine has also been reported in cutaneous leukocytoclastic vasculitis including IgA-V, but without clinical studies supporting this attitude.
The FAMILYVASC study is a prospective observational study which will aim to identify susceptibility loci and genes for systemic vasculitis risk in patients with familial or pediatric forms of vasculitis. Genetic analysis based on whole exome sequencing will be carried out through salivary DNA.
Mechanistic study to assess whether dual B-cell immunotherapy by co-administration of rituximab and belimumab will result in improvements in biological endpoints, functional outcomes and clinical status compared to rituximab with placebo.
Most recent insights in the treatment for patients with ANCA-associated vasculitis (AAV) have demonstrated that 'tailored' maintenance treatment with rituximab (RTX) is effective to achieve durable remission of disease. As such, RTX re-treatment can be tailored on the basis of relevant clinical and immunological parameters in AAV patients. Now, the present study intends to evaluate whether combining rituximab with cyclophosphamide is superior to current standard of care with rituximab only to induce a favorable clinical and immunological state in AAV patients and can thereby reduce the number of tailored re-treatments with rituximab.
This case control study aims to determine whether spontaneous coronary artery dissection (SCAD) is associated with autoimmune diseases and to update the incidence of SCAD in a population-based cohort.
This study will assess the effect of a mindfulness meditation program administered via a smartphone application on health-related quality of life for patients with rheumatic disease.
The purpose of this study is to determine whether plasma exchange as well as immunosuppressive therapy are effective in reducing death and end-stage renal disease (ESRD). The trial will also study whether a reduced cumulative dosing regimen of glucocorticoids is as effective as a standard disease regimen. The FDA-OOPD is one of the funding sources for this study.
Large vessel vasculitis (LVV) causes blood vessel inflammation leading to pain, fatigue and complications such as aneurysm formation and stroke. Treatments used can have significant side-effects. Doctors find it difficult to determine when to start and stop treatment, often leading to over- or under-treatment. A new test is required to determine disease activity that will guide treatment more accurately. This study will recruit participants with active LVV from throughout Scotland in order to assess the ability of two new types of scan - positron emission tomography with magnetic resonance imaging (PET/MR) and retinal optical coherence tomography (OCT) - to determine disease activity. In addition, I will investigate the link between LVV and heart disease.
ANCA vasculitis is a pauci-immune systemic small vessel vasculitis. The anti-neutrophilic cytoplasmic antibodies (ANCA) are pathogenic and cause disease by activating neutrophils which damage blood vessels. CD means "cluster of differentiation" . CD5 is a type I transmembrane protein found on T cells, thymocytes, and some B cells. CD20 is a type III transmembrane protein found on B cells. The investigators previously detected an association between recovery of Interleukin 10 (IL-10)-secreting CD20+ and CD5+ regulatory B cells after immunotherapy (with rituximab and corticosteroids) and decreased risk of subsequent relapse in patients with ANCA-vasculitis. The investigators hypothesize that patients with complete reconstitution of a functional regulatory B cell repertoire after induction therapy are at low risk of relapse and may be monitored conservatively without further immunotherapy. The investigators will test this hypothesis through a proof of concept randomized controlled study. Patients with normalization of CD5+ regulatory B cells will be randomized to maintenance therapy with rituximab vs. close observation without immunosuppression. Patients whose peripheral CD5+ regulatory B cells remain low after induction therapy (who are at higher risk of relapse), will receive maintenance immunosuppression with rituximab. Patients needing or randomized to maintenance therapy who are unable to receive rituximab will receive azathioprine or mycophenolate mofetil, two standard alternative medications for maintenance immunosuppression.
TIPIC syndrome (previously called carotidynia) is a rare entity of unknown cause, where the patient has a temporary cervical pain associated with a suggestive inflammation around the carotid artery. Usually considered as a unique and benign episode, some patients have recurrences and the follow-up is usually short. In this study the investigators aim to evaluate patients who presented a TIPIC episode at least 3 months before, clinically and with a cervical doppler ultrasound
