Filter by:Relapsing polychondritis (RP) is a rare systemic inflammatory disease characterized by recurrent inflammation of cartilage including ears, nose, tracheobronchial tree, chest wall and joints. Less commonly, it can cause inflammation of eyes, vasculature, nervous system, skin and inner ear. The purpose of this study is to study the pathogenesis of RP.
This is a prospective observational study to determine the frequency and magnitude of Cytomegalovirus (CMV) reactivation in patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) in the acute phase of the disease (within 12 months of diagnosis or relapse and commencement of induction of remission therapy) and its association with clinical outcomes. The investigators will also explore whether CMV reactivation causes an increase in CCR2 expressing monocytes, and whether these monocytes cause persistent kidney damage in AAV. The investigators hypothesise that reactivation of CMV during the initial 12 months following diagnosis or relapse of AAV occurs frequently but is generally asymptomatic. Based on the investigators' preliminary data the investigators further hypothesise that subclinical reactivation of CMV during this period will be associated with adverse clinical outcomes, including the severity of vasculitis, the response to treatment and the damage caused by vasculitis. Finally, they hypothesise that subclinical CMV reactivation leads to amplification of renal damage in AAV through a monocyte CCR2/CCL2 driven pathway. The investigators' research has recently shown that asymptomatic reactivation of CMV is a frequent event in AAV patients, occurring in roughly 25% of AAV patients in remission. However, the frequency of asymptomatic reactivation of CMV during the acute phase of the disease is not known. The investigators have previously shown that CMV infection and surrogate markers of CMV reactivation in patients with AAV are associated with worse outcomes such as reduced kidney function, increased risk of infection and death, increased risk of blood clots and increased stiffness of the blood vessels, which is a risk factor for heart disease and stroke. The investigators also have preliminary findings suggesting that in patients with AAV and CMV reactivation, the more CCR2 expressing monocytes in the blood, the worse the kidney function. If CMV reactivation during the acute phase of the disease is common and linked with worse outcomes, this study may then lead on to future research involving treatment to prevent CMV reactivation aiming to improve patient outcomes. The investigators will be looking to recruit patients under the care of the Queen Elizabeth Hospital with newly diagnosed or recently relapsed AAV in the last 2 weeks who are positive for previous CMV infection.The investigators will follow these patients up with 10 visits over 12 months; where possible these will coincide with participants' usual vasculitis clinic appointments. At each visit the participants will be required to give blood and urine samples and answer questions related to their vasculitis. Kidney biopsy tissue taken at diagnosis will be used to assess mechanisms of injury during CMV reactivation.
This study is a prospective, open-labelled, randomized, controlled,multi-center clincial trial. The aim of this study is to verify that the remission rate of patients treated with Leflunomide is not inferior to that of patients treated with Azathioprine.
Initial worsening following initiation of rituximab therapy in patients with cryoglobulinemic vasculitis was described in 3.6% of cases. This worsening is often a serious condition, with high levels of mortality. The objective of our study is to evaluate the efficacy of preventive plasmapheresis prior to the introduction of rituximab performed in Montpellier France since 2013 by assessing the frequency and severity of this flare effect in these patients compared to those reported in the literature.
To date, there is no available tool that allows, at individual level, determination of the probability to develop clinically relevant complications of prolonged glucocorticoid therapy. In patients with inflammatory rheumatic disorders requiring prolonged glucocorticoid therapy, such tool could be useful to adapt first-line treatment decisions (in daily practice and in future clinical trials). The main objective of the study is to identify routine clinical, biological and DXA baseline characteristics predictive of the occurrence of clinically relevant complications of glucocorticoid therapy at 1 year, in order to propose a predictive score.
VASCO is a prospective observational cohort study which aim to describe the presentation, comorbidities, management, outcomes and damage of vasculitis patients, from the analysis of the clinical, biological and immunological data.
Systemic lupus erythematosus (SLE) is a complex heterogeneous autoimmune disease with a wide variety of clinical and serological manifestations that may affect any organ. Vasculitis prevalence in SLE is reported to be between 11% and 36%.
The purpose of this study is to find out whether hydroxychloroquine, in addition to background treatments, reduces disease activity in patients with Anti-Neutrophilic Cytoplasmic Autoantibodies (ANCA) Vasculitis, a group of autoimmune diseases. Hydroxychloroquine and is an established, effective, safe and inexpensive therapy, widely used in other autoimmune diseases such as lupus and rheumatoid arthritis. The study is open to adults diagnosed with certain types of vasculitis, called Granulomatosis Polyangiitis (GPA), Microscopic Polyangiitis (MPA) or Eosinophilic Granulomatosis with Polyangiitis (EGPA). Participants will be eligible if they are treated with background medication to control their vasculitis disease and have a low level of disease activity as defined by a Birmingham Vasculitis Activity Score (BVAS) of greater than 3. Participants will be randomly placed in 1 of 2 groups. Both groups will be given background medication. One group will receive hydroxychloroquine and the other will receive placebo. Participants will be on treatment for 1 year. 76 ANCA Vasculitis participants will be recruited (38 in each treatment arm) from UK vasculitis specialist centres.
Immune checkpoint inhibitors (ICIs) might induce high grade immune-related adverse events (irAEs) involving the cardio-vascular system. This study investigates reports of cardio-vascular toxicity associated with treatment including anti-PD1, Anti-PDL-1, and Anti CTLA4 classes using the World Health Organization (WHO) database VigiBase, Assistance Publique Hopitaux de Paris Entrepot de Données de Santé (APHP.EDS), French Système National Des Données de Santé (SNDS) Databases and a retrospective international multicenter registry of ICI-associated myocarditis
Autoimmune diseases, such as systemic lupus erythematosus, rheumatoid arthritis, myositis, or anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, may affect multiple organ systems. Occasionally, patients deteriorate acutely requiring advanced care in an intensive care unit (ICU). In an ICU setting, mortality is estimated with scoring systems, such as APACHE or SAPSII. Since there are limited data available on their use in autoimmune diseases, with the current study, we aim to assess the usefulness of these ICU scores and analyze predictors of mortality in this particular group of patients.
