Filter by:This study evaluates the long- term safety and effectiveness of adalimumab in participants with non-infectious intermediate-, posterior-, or pan-uveitis in daily practice in Japan.
Background: Uveitis is an inflammation of the eye that can cause vision loss. It is treated with medications and sometimes surgery. However, in many people, treatment does not always prevent loss of vision. A new medication, ustekinumab, reduces inflammation in patients with other inflammatory diseases. Therefore, it might be helpful in treatment of uveitis. Objective: To see if ustekinumab is safe and can help people with uveitis. Eligibility: People ages 18 and older with uveitis Design: Participants will be screened with: Medical and eye disease history Physical exam Eye exam: The pupil is dilated with eye drops. A machine scans the back of the eye. Pictures are taken of the inside of the eye. Blood and urine tests Tuberculosis test Participants will have 6 clinic visits over 28 weeks. Visits lasts 2-3 hours and include: - Medical and eye disease history - Physical and eye exams - Blood and urine tests - Fluorescein angiography: A needle guides a thin plastic tube into an arm vein. A dye is injected into the tube. The dye travels through the veins up to the blood vessels in the eyes. A camera takes pictures of the dye as it flows through the blood vessels in the eyes. - Cohort 1 - Ustekinumab injections at Weeks 0, 4, and 8: The injection is under the skin of the upper arm, leg, or abdomen. Participants will have their uveitis monitored and receive standard uveitis care during the study. - Cohort 2 - Ustekinumab injections via intravenous (IV) injection at first visit, followed by a single 90 mg injection of ustekinumab under the skin of the upper arm, leg or abdomen. For the IV injection a needle will be used to guide a thin plastic tube (catheter) into one of the arm veins. The needle will be removed, leaving only the catheter in the vein.
Optical Coherence Tomography (OCT) is routinely used in ophthalmic clinical practice. It uses infrared light to image patient's eyes. Some patients, such as those with an inflammatory disease called uveitis or those who have just undergone cataract surgery, have intraocular inflammation. This intraocular inflammation commonly manifests as cells that can be seen on routine microscopic clinical examination. However, the only currently available method to quantify this intraocular inflammation is by manually counting on the microscopic clinical examination. The investigators plan to use the OCT machine to image patient's eyes. The investigators will then use the images obtained from the OCT to objectively quantify the degree of intraocular inflammation.
This study investigates the variations in the retinal nerve fiber layer (RNFL) thickness during uncomplicated anterior and intermediate uveitis, respectively. The objectives are to 1 ) confirm the RNFL thickening during an uncomplicated anterior uveitis as described in the literature, 2) measure the RNFL thickness during an uncomplicated intermediate uveitis specifically and 3) describe the variation in time of RNFL thickness during the two types of uveitis.
Toxoplasmosis affects one to two newborn each 10000 births. Among them, 1 to 2 % develop learning disabilities or die, and 4 to 27 % develop a chorioretinitis sometimes leading to an amblyopia responsible for visual impairment. Toxoplasmosis uveitis affects too adults immunocompetent and immunodepressed who have had an acquired toxoplasmosis. Clinical diagnosis of ocular toxoplasmosis is more complicated in presence of posterior neuro-retinitis, inflammation of the papilla, uveitis without chorioretinitis, fuchs heterochromic iridocyclitis, scleritis, diffuse necrotizing or multifocal retinitis. In this situation biological markers diagnostic and prognostic of toxoplasmosis uveitis are useful. Highly kept molecules (during evolution) like stress proteins (Hsp) are are found in the host and the pathogen and there can trigger a crossed immune response. Stress proteins haven't been explored yet, in the context of toxoplasmosis uveitis on humans. The hypothesis is that Hsp70 and antibodies anti-Hsp70 are diagnostic and prognostic markers of ocular toxoplasmosis. The goal is to evaluate diagnosis value of biological markers (Hsp70 and antibodies IgG anti-Hsp70) in toxoplasmosis uveitis.
Our research project is to use a new microbiological diagnostic strategy of uveitis, allowing detection of the fastidious pathogens of infectious Uveitis who are not diagnosed by laboratory methods used in diagnostic routine. This new diagnostic strategy is to automatically detect the presence of a pathogen fastidious in cell culture using the same patient's serum to reveal a positive culture, based on the assumption that this serum contains antibodies specific pathogen tedious. Finally, the main purpose of this study is to improve the etiological diagnosis of Uveitis by establishing a new diagnostic strategy.
Uveitis is an acute or chronic inflammatory condition of unknown etiology. Although uveitis often responds adequately to topical corticosteroids, there are many patients for which this treatment is either inadequate or not tolerated. A patient with inadequate response to treatment would manifest uveitis activity by slit lamp examination determination of anterior chamber cellularity. Lack of tolerance of therapy commonly manifests as ocular hypertension (greater than 21 mmHg measured by tonometry)complicating chronic topical corticosteroid administration, leading to glaucoma and permanent visual loss. Moreover, systemic corticosteroids may be required at a dose unsafe for chronic administration. In these situations, an immunosuppressive medication is often added as a "steroid-sparing" agent. If and when there is clinical response to the added immunosuppressive, the oral and/or topical corticosteroid dose can be reduced or eliminated to avoid toxicity. There are several reasons for believing that Acthar might be beneficial in the treatment of uveitis patients. In addition to increasing adrenal production or cortisol, Acthar has another important mechanisms of action mediated by its binding of melanocortin receptors. Melanocortin down-regulates activity of B and T lymphocytes, monocytes and macrophages. In animal studies, melanocortin peptides down-regulate T helper cells, up-regulate T Regulatory cells, and decrease B lymphocyte production of B Lymphocyte Stimulator. In macrophages, there is down-regulation of IL-1, IL-2, INF gamma, TNF alpha, nitric oxide and adhesion molecules. In other cells, in addition to IL-10 upregulation (monocytes), there is down-regulation of VACM and ECAM (endothelial cells), prostaglandins (fibroblasts) and MCP-1 and RANTES (renal tubules).CNS mediation of systemic inflammation may also be down-regulated by melanocortin receptor binding by Acthar.
Uveitis is a disease that affects over 2 million people around the globe, and can ultimately lead to blindness. The proportion of patients with uveitis who become blind has not been reduced over the past 30 years, and this is therefore an area that demands further research. One of the major causes of blindness in uveitic patients is the development of uveitic glaucoma, which occurs in 10-20% of uveitic eyes. This is likely to occur for reasons related to the uveitis itself, but can also be caused as a side effect of the corticosteroids used to treat uveitis. The raised IOP in uveitis is more difficult to treat than other types of glaucoma. To enable more effective treatment of uveitic glaucoma, the investigators need to understand more clearly the mechanisms which underlie this process. The investigators therefore propose a study to examine the contribution of altered aqueous dynamics to the development of raised IOP in uveitis.
Uveitis represents a heterogeneous group of diseases that results from ocular inflammatory reaction involving ocular tissue and vasculature. The inflammation usually causes pain, redness, photophobia and blurred vision. This inflammation, is typically treated with regional or systemic therapy. The regional therapy typically consists of topical corticosteroids or periocular or regional corticosteroids. Regional therapy can lead to a steroid response glaucoma, which is increased intraocular pressure.This pilot study aims to evaluate the possible effectiveness of H.P. Acthar in patients with active ocular inflammatory disease, and currently on treatment for glaucoma or have a history of glaucoma.
This trial is a 12 month, Phase 3, multi-center, randomized, single-masked (subject), controlled study designed to evaluate the utilization and safety of the Mk II inserter and the safety of the FAI insert, in subjects with non-infectious uveitis affecting the posterior segment of the eye.
