Filter by:Milatuzumab will be given subcutaneously at different dose levels once (depending on the dose level) for 4 weeks to determine if milatuzumab helps to control lupus (SLE).
Cutaneous vasculitis due to vascular deposition of large circulating immune complexes is a disease frequently seen by general practitioners and dermatologists. The clinical symptom is palpable purpura with predilection for the lower legs. In some cases vasculitis also affects systemic organs, such as the kidneys and the intestine. When the immune complexes contain immunoglobulin class A (IgA) and when there is systemic involvement, the disease has been referred to as Henoch Schönlein purpura. When there are no signs of systemic involvement, the disease has been referred to as cutaneous leukocytoclastic angiitis. The investigators hypothesize that palpable purpura with predilection for lower legs is a pathognomonic clinical sign for immune complex vasculitis in both IgA vasculitis and IgA-negative vasculitis, but that only the presence of IgA in immune complexes is likely to be associated with systemic involvement and therefore warrants more extensive diagnostic procedures Vice versa the investigators postulate that the presence of IgG or IgM without IgA in immune complexes excludes systemic involvement The investigators also want to investigate to which of the 2 groups patients with palpable purpura and negative immunofluorescence should be assigned.
The purpose of this study is to evaluate the ability of contrast enhanced carotid ultrasound to serve as an indicator of disease activity in patients with Takayasu's arteritis or Giant Cell arteritis and to determine if patients with active arteritis have a thickening of their blood vessel walls compared to healthy people of the same age and gender.
The aim of this study is to assess the efficacy of a rituximab regimen based on rate of ANCA and CD19 lymphocytes for maintenance treatment in systemic ANCA-associated vasculitis: prospective, multicenter, controlled, randomized comparative study of two rituximab regimens: one based on ANCA and CD19 lymphocytes versus systematic infusions.
A qualitative study using interviews with patients who have antineutrophil cytoplasm antibody (ANCA) associated vasculitis, to develop a patient reported outcome (PRO)measure
Rituximab is now established as an effective drug for anti-neutrophil cytoplasmic antibody (ANCA) vasculitis following major European and US trials reported in 2010. After a time, its effect wears off and the disease can return. This occurs in at least half of patients within 2 years of receiving Rituximab. A preliminary study in Cambridge has suggested that repeating rituximab every six months stops the disease returning and is safe. The RITAZAREM trial will find out whether repeating rituximab stops vasculitis returning and whether it works better than the older treatments, azathioprine or methotrexate. It will also tell us how long patients remain well after the repeated rituximab treatments are stopped, and if repeated rituximab is safe. We should also learn useful information about the effects of rituximab on quality of life and economic measures. The trial results will help decide the best treatment for future patients who have their vasculitis initially treated with rituximab. RITAZAREM aims to recruit patients with established ANCA vasculitis whose disease has come back 'relapsing vasculitis'. All patients will be treated with rituximab and steroids and we anticipate that most will respond well. If their disease is under reasonable control after four months, further treatment with either rituximab (a single dose ever four months for two years) or azathioprine tablets will be chosen randomly. The patients in the rituximab and azathioprine groups will then be compared. Patients will be in the trial for four years. The study has been designed by members of the European Vasculitis Study group (EUVAS) and the Vasculitis Clinical Research Consortium (VCRC). It will include 190 participants from 30 hospitals in Europe, the USA, Australia and Mexico. RITAZAREM is being funded by Arthritis Research UK, the U.S. National Institutes of Health and by Roche/Genentech.
This CARRA Registry study will create a foundational database for rheumatic diseases of childhood using a novel informatics infrastructure developed as part of the larger clinical project. The creation of a CARRA-wide informatics infrastructure will enable efficient, observational, disease-related data capture across all CARRA sites for pediatric rheumatic diseases. The CARRA Registry study will demonstrate the feasibility of expanding to more data intensive registries for observational studies, comparative effectiveness research, pharmaceutical clinical trials and translational research.
The purpose of this study is to evaluate the efficacy and safety of belimumab, in combination with azathioprine, for the maintenance of remission following a standard induction regimen in patients with Wegener's granulomatosis or microscopic polyangiitis. The random assignment in this study is "1 to 1" which means that participants have an equal chance of receiving belimumab or placebo.
The purpose of this study is to determine whether Cytomegalovirus (CMV) reactivation in ANCA-associated vasculitis (AAV) patients can be effectively and safely reduced using an antiviral agent (valaciclovir) and whether this in turn improves the function of the immune system thereby also improving the body's ability to fight other infections. The primary hypothesis is that repeated episodes of CMV reactivation in AAV patients drive the expansion and functional impairment of CMV-specific T-cells, with increased susceptibility to infection. Inhibition of CMV replication with valaciclovir will block further stimulation of CMV specific T-cells and increase the functional capacity of the immune system.
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.
