Filter by:This is a french multicenter observational study assessing safety and efficacy of biosimilar of Tocilizumab in Giant Cell Arteritis (GCA) with active aortitis, including 14 reference centers from the Groupe d'Etude Français des vascularites des gros vaisseaux (GEFA). Giant Cell Arteritis (GCA), formerly known as temporal arteritis, is the most common form of systemic vasculitis in patients aged ≥ 50 years. GCA is defined by granulomatous arteritis that affects large#sized and medium#sized blood vessels with a predisposition to affect the cranial arteries. Aortitis accounted for more than 50% of GCA patients with the new imaging techniques. Aortitis is typically diagnosed using imaging tests such as magnetic resonance imaging (MRI) or Computed Tomography (CT) scans. Aortitis is an inflammation of the aorta, leading to a range of symptoms such as fever, weight loss, fatigue, and chest pain. In severe cases, aortic aneurysms or aortic dissection can occur, which can be life-threatening. Multiple reports have demonstrated the presence of abnormal pro-inflammatory cytokine production in large-vessel vasculitis patients, particularly those with GCA, including interleukin-1 (IL-1), IL-6, IL-18, tumor necrosis factor-α (TNF-α), and interferon-γ, by T lymphocytes and macrophages. IL-6 has been implicated as a crucial cytokine in the pathogenesis of aortitis and targeting its signaling has shown promising results in treating the condition. IL-6 inhibitors such as tocilizumab have been found to effectively reduce disease activity and improve clinical outcomes in GCA patients. The GIACTA study (GiAnt cell arteritis roActemra (tocilizumab) study) was a randomized, double-blind, placebo-controlled trial that evaluated the efficacy and safety of tocilizumab in the treatment of GCA. The study included 251 patients with newly diagnosed or relapsing GCA and found that treatment with tocilizumab significantly increased the proportion of patients who achieved sustained remission from GCA at 52 weeks, compared to placebo. Additionally, tocilizumab was associated with a lower incidence of disease flares and a reduced need for glucocorticoid therapy. Following the positive results of the GIACTA study, tocilizumab was approved for the treatment of GCA in adults with active disease, including aortitis, who have not responded to glucocorticoids, or for whom glucocorticoid therapy is not appropriate, by regulatory agencies around the world, including the US Food and Drug Administration and the European Medicines Agency. However, the efficacy of IL-6 inhibitors on aorta inflammation as assessed by modern and powerful imaging techniques has never been specifically studied in GCA. This observational study will provide important informations on the impact of Tyenne® (tocilizumab) associated with short term low dose steroids on clinical manifestations and vessel inflammation and damage in aortitis of GCA.
Inflammatory aortitis probably represents a heterogeneous group, and the clinical experience accumulated over the last ten years, shared by the experts of the subject, is that the initial clinical, biological or radiological characteristics should make it possible to differentiate them and dismember the Nosological field. This will be an essential first step before studying prognosis, risk factors, and therapeutic options. The search for diagnostic criteria on a large series, similar to the study of classification of vascularites of the ACR in 1990, should make it possible to homogenize the diagnoses for the different teams working on the subject, and to begin work Collaborations, which alone can improve patient care in the future.
The term 'aortitis' refers to inflammation of the aorta. Aortitis is known to occur in a variety of vasculitides and connective tissue diseases, such as giant cell arteritis (GCA), Takayasu arteritis (TAK), rheumatoid arthritis, and spondyloarthropathies, among others. This study will establish a longitudinal cohort for these diseases.
The purpose of this study is to collect existing tissue specimens from subjects enrolled in Vasculitis Clinical Research Consortium (VCRC) studies. Analysis of these tissue specimens and linked clinical data collected through VCRC studies may lead to the identification and development of a series of translational research projects. Results of these studies will provide vasculitis researchers with insight into the causes of these diseases and generate new ideas for diagnostic tests and therapies, and will be of great interest to the larger communities of researchers investigating vasculitis and other autoimmune, inflammatory, and vascular diseases.
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.
