Filter by:Necrotizing Vasculitis are inflammatory diseases of the wall of vessels. Neurological damage of the peripheral nerve varies from 7% to 50% of cases depending on the type of Necrotizing Vasculitis. Peripheral neurological impairment is rarely life threatening (except when associated with other visceral impairment which, in turn, require urgent management with a severity score defined by the Five Factor Score) but impacts the functional outcome by sequelae evaluated by the Vascular Disease Index (VDI). Four retrospective studies were published with low number of participants, and also mix subgroups of vasculitis Anti-Neutrophil Cytoplasmatic Antibodies (ANCA)+/- GPA (Granulomatosis with polyangiitis), Eosinophilic granulomatosis with polyangiitis (EGPA), Microscopic polyangiitis (MPA), Polyarteritis nodosa (PAN), and Non Systemic Vasculitic Neuropathy (NSVN) and Systemic Vasculitic Neuropathy (SVN). Overall, management of Necrotizing Vasculitis has evolved significantly over the last two decades, with a dramatic improvement in survival, thanks to new therapeutic strategies and medications. Five-year survival increased from 85% for diagnoses made between 1990 and 1999 to 94.5% for diagnoses made after 2010 Evaluation of relapses of vasculitis, late macro vascular complications, medical-economic evaluation of therapeutic strategies and functional impairment of neuropathies are at the heart of current medical concerns with a view to improve vital and functional prognosis. Various tests for the evaluation of peripheral neurological damage appear to be relevant tools in vasculitis, although they are not specific: Muscular force scale Medical research council (MRC), Rasch-built overall disability scale (RODS), Inflammatory Neuropathy Cause and Treatment (INCAT) disability score, Construction and validation of the chronic acquired polyneuropathy patient-reported index (CAP-PRI), Health-Related Quality of Life (HR QOL), Medical Interview Satisfaction Scale (MISS), Neuropsychological Impairment Scale (NIS) associated to results of repeated Electromyography. In this study, MRC, NIS and RODS measurements were chosen for their reproducibility and practicality. In addition to the immediate or relapse mortality factors assessed by the five-factor score (FFS), a functional morbidity score specific to neuropathies related to necrotizing vasculitis must be developed, as well as the determination of the neurosensory disorders and macro-vascular complications. Therefore it is proposed in this observational study to determine the factors that can be predictive of the functional evolution, in order to build a risk score.
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 the best management strategy to maintain remission in patients with ANCA vasculitis who have been treated with rituximab induced B cell depletion for at least two years. This study will compare intermittent B Cell depletion upon B cell return or intermittent B cell depletion upon serologic relapse.
Multicenter randomized double-blind study comparing the efficacy and safety of rituximab in combination with corticosteroids to corticosteroids plus placebo in the treatment of non-infectious active mixed cryoglobulinemia vasculitis.
The aim of the investigators' study is to evaluate whether monitoring serum rituximab levels could be an interesting tool in the follow-up of ANCA-associated vasculitis patients. All consecutive patients, hospitalized for a new diagnosis of ANCA-associated vasculitis or the relapse of a known ANCA-associated vasculitis, in which the decision to start an induction regimen with rituximab has been taken, will be included. Serum rituximab levels (along with serum anti-rituximab antibodies levels) will be determined (at M+1 and M+3) and the correlation with clinical outcome at M+6 will be analyzed.
The clinical efficacy of double filtration plasmapheresis(DFPP) in patients with antineutrophil cytoplasmic autoantibody associated glomerulonephritis(AAGN).
The goal of the study is to find biological markers (certain proteins or cellular markers found in a blood test) that will inform doctors which patients diagnosed with ANCA-associated vasculitis (AAV) are most likely to be able to stop their medications suppressing their immune systems and remain in remission.
People with rheumatic disease often have decreased strength, muscle mass, and bone mineral density due to repeated bouts of inflammation, normal effects of aging, disuse, and inactivity. The medications used to quell the disease process, such as prednisone, can also have detrimental effects on body composition, strength, and functional capacity. The investigators propose to investigate the feasibility, safety, and effects of resistance exercise in older patients with rheumatoid arthritis (RA) and vasculitis. The unique resistance protocol the investigators propose involves performing movements in a slow and controlled fashion (i.e., no acceleration or use of momentum in the lifting and lowering of the resistance) to minimize force on the joints and connective tissues. This will be conducted in an individually-supervised environment with a new generation of exercise equipment that will accommodate their musculoskeletal capabilities and allow for reproducibility of the exercise protocol. The investigators intend to investigate the feasibility, safety, musculoskeletal, and psychological effects of this resistance exercise protocol in older patients with rheumatoid arthritis and vasculitis by testing their strength, body composition, functional ability, mood, and quality of life before and after this 16-week resistance exercise intervention.
Rituximab is the first drug approved by the United States Food and Drug Administration (FDA) for the treatment of patients with granulomatosis with polyangiitis (Wegener's granulomatosis) or microscopic polyangiitis. Because it is a relatively new medication, the long-term safety and efficacy of this drug is not yet clear. This study proposes to follow patients who were enrolled in the RAVE study to determine if treatment with rituximab influences long-term outcomes.
The purpose of this study is to test whether additional therapy with plasma exchange improves the chances of kidney recovery in severe kidney vasculitis.
