Filter by: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.
Several drugs and chemotherapies seem to induce uveitis. This study investigates reports of uveitis, including the International classification of disease ICD-10 for treatments in the World Health Organization (WHO) global Individual Case Safety Report (ICSR) database (VigiBase).
Optical Coherence Tomography (OCT) machines are non-contact instruments that can provide micrometer scale imaging of biological tissue. Applying the image processing allows us to automatically measure the choroidal thickness with good interclass correlation coefficient to the manual measurements.
reviewing the outcomes of patients with uveitis caused by autoimmune diseases treated at Assiut University Hospital at the Ophthalmology and Rheumatology and Rehabilitation Departments.
Uveitis or inflammation of the uveal tract results from a heterogeneous collection of disorders of varying etiologies and pathogenic mechanisms. Uveitis is relatively frequent in industrial countries with an estimation of 115 cases for 100 000 persons and is associated with a blindness risk of 10%. Causes of uveitis can be related to different etiologies (infectious, inflammatory or general inflammatory diseases). Therapeutic care is based on ophthalmologic and systemic diagnosis and treatment strategy depends on the severity of inflammation. The main objective of the Lyon uveitis study is to analyze the uveitis ophthalmologic etiology and diagnostic and therapeutic care of the patients. This study is proposed to all patients diagnosed for uveitis and referred to the Department of Internal Medicine of the Croix Rousse hospital, Lyon, france for etiologic diagnosis or treatment. Analysis of i) patients' characteristics, ii) the relevance of complementary exams to determine the uveitis etiology, iii) treatment used. This study will allow a better characterization of the disease on diagnosis practices and therapeutic care.
To assess the efficacy and safety of Abatacept as an immunosuppressive treatment in Birdshot uveitis. The primary objective is to test the efficacy to suppress inflammation in active Birdshot uveitis patients, using quantitative and qualitative measurements of visual function.
Sarcoidosis is a systemic disease with unknown etiology. Chronicity of the disease is observed in 1/3 of cases. Five percent of the affected patients are expected to die due to pulmonary worsening. After pulmonary complications, ocular complications are one of the most frequent complications. In hospital setting 2 to 15% of patients who come for initial uveitis diagnosis are after examination due to Sarcoidosis. Sarcoidosis diagnosis is based on paraclinical exams (biological, radiography) and histological confirmation. Corticotherapy (local or general) is usually used to cure sarcoid uveitis. In case of failure immunosuppressor or anti-tumor necrosis factor (TNF) can be used. In 10% of cases ocular symptoms including blindness are observed. Only treatment administrated quickly after diagnosis of sarcoid uveitis can prevent from ophthalmologic complications. The main objective of the Lyon Sarcoid Uveitis Cohort study is to analyze the relevance of the paraclinical exam for sarcoid uveitis diagnosis, and to define a better visual and extra-ophthalmologic prognosis and describe the therapeutic practice in our Department. This study is proposed to all patients diagnosed with Sarcoid uveitis with a histological confirmation and referred to the internal medicine department of the Croix-Rousse hospital, Lyon, France, for etiologic diagnosis or treatment.
Uveitis is characterized by inflammation of the uvea, which is the middle portion of the eye. The greatest challenge for the treatment of uveitis is patients who have inflammation involving the posterior segment, either primarily in the vitreous (intermediate uveitis), the choroid or retina (posterior uveitis), or involving the entire eye (panuveitis). The term "uveitis" denotes a heterogeneous collection of diseases including infections, systemic immune-mediated diseases like sarcoidosis, and immune-mediated syndromes confined to the eye like sympathetic ophthalmia. Despite the progress in recent decades, uveitis and the related intraocular inflammation are comparable to diabetes or macular degeneration as a cause of lost quality-adjusted life years due to visual morbidity, and as such are a significant public health problem. The Standardization of Uveitis Nomenclature Working Group Guidelines recommend the use of corticosteroids as the first-line therapy for patients with active uveitis. However, long-term corticosteroid treatment can cause serious systemic and ocular side effects, such as hypertension, diabetes, osteoporosis, cataract, and glaucoma that limit its use in the treatment of uveitis. Alternatively, immunomodulatory therapy (IMT) drugs are given as steroid-sparing agents and have shown good clinical results for both systemic diseases and ocular inflammatory diseases. Given the side effects of chronic corticosteroid therapy and better understanding of the mechanisms of autoimmune-mediated uveitis, the aim of the treatment for patients with noninfectious uveitis is steroid-free remission with IMT. While uveitis is a heterogeneous disease with polygenic and environmental factors, most forms of immune-mediated uveitis are thought to be due to an imbalance between regulatory mechanisms that inhibit the immune system and inflammatory mechanisms, which have evolved to rid the body of infectious organisms, but which can result in immune-mediated, often chronic disease if they are activated outside the context of the immediate infection. The pathophysiology of non-infectious uveitis involves the rupture of peripheral tolerance, resulting in auto-aggressive Th1 or Th17 lymphocytes reaching the eye. L-12 and IL-23 are two key cytokines involved in Th1 and Th17 polarization in uveitis, respectively. Furthermore, these two cytokines share a common subunit (p40). Ustekinumab, a humanized anti-p40 monoclonal antibody, is able to target both IL-12 and IL-23 pathways, thus disrupting Th1 and Th17 immune responses. Decreasing the dose as well as the duration of treatment with GC is of particular importance in uveitis, and ustekinumab, which selectively inhibits Th1 and Th17 pathways in the inflammatory cascade, could provide a ideal additional therapy for non-infectious severe uveitis (NISU) to reach this objective. Therefore, in the present study, we propose to evaluate the efficacy and safety of ustekinumab for the treatment of NISU.
Non-infectious intermediate, posterior, and panuveitides are chronic, potentially-blinding diseases. Vision-threatening cases require long-term therapy with oral corticosteroids and immunosuppression. Based upon preliminary data, adalimumab, a fully-human, anti-TNF-α monoclonal antibody, now US FDA-approved for uveitis treatment, may be a superior corticosteroid-sparing agent than conventional immunosuppressive drugs. The ADVISE Trial is multicenter randomized, parallel-treatment, comparative effectiveness trial comparing adalimumab to conventional (small molecule) immunosuppression for corticosteroid spring in the treatment of non-infectious, intermediate, posterior, and panuveitides.
The proposed study is a stratified, block-randomized, double-masked, controlled trial to determine the feasibility of discontinuing adalimumab treatment in patients with quiescent uveitis associated with juvenile idiopathic arthritis (JIA) or chronic anterior uveitis (CAU).
