Bevacizumab diminishes inflammation in an acute endotoxin-induced uveitis model
2017
Este artículo se encuentra disponible en la página web de la revista en la siguiente URL: https://www.frontiersin.org/articles/10.3389/fphar.2018.00649/full Introduction: Uveitis is an eye disease characterized by inflammation of the uvea and an early and exhaustive diagnosis is essential for its treatment. The aim of our study is to assess the potential toxicity and anti-inflammatory efficacy of Bevacizumab in an experimental uveitis model by subcutaneously injecting lipopolysaccharide into Lewis rats and to clarify its mechanism. Material and Methods: Blood–aqueous barrier integrity was assessed 24 h after endotoxin-induced uveitis (EIU) by analyzing two parameters: cell count and protein…
New insights into the genetic component of non-infectious uveitis through an Immunochip strategy.
2016
BACKGROUND: Large-scale genetic studies have reported several loci associated with specific disorders involving uveitis. Our aim was to identify genetic risk factors that might predispose to uveitis per se, independent of the clinical diagnosis, by performing a dense genotyping of immune-related loci.METHODS: 613 cases and 3693 unaffected controls from three European case/control sets were genotyped using the Immunochip array. Only patients with non-infectious non-anterior uveitis and without systemic features were selected. To perform a more comprehensive analysis of the human leucocyte antigen (HLA) region, SNPs, classical alleles and polymorphic amino acid variants were obtained via impu…
Signature of Circulating Biomarkers in Recurrent Non-Infectious Anterior Uveitis. Immunomodulatory Effects of DHA-Triglyceride. A Pilot Study
2021
The purpose of this study was to identify circulating biomarkers of recurrent non-infectious anterior uveitis (NIAU), and to address the anti-inflammatory effects of triglyceride containing docosahexaenoic acid (DHA-TG). A prospective multicenter study was conducted in 72 participants distributed into: patients diagnosed with recurrent NIAU in the quiescence stage (uveitis group (UG)
Widening use of dexamethasone implant for the treatment of macular edema
2017
Vincenza Bonfiglio, Michele Reibaldi, Matteo Fallico, Andrea Russo, Alessandra Pizzo, Stefano Fichera, Carlo Rapisarda, Iacopo Macchi, Teresio Avitabile, Antonio Longo Department of Ophthalmology, University of Catania, Catania, Italy Abstract: Sustained-release intravitreal 0.7 mg dexamethasone (DEX) implant is approved in Europe for the treatment of macular edema related to diabetic retinopathy, branch retinal vein occlusion, central retinal vein occlusion, and non-infectious uveitis. The implant is formulated in a biodegradable copolymer to release the active ingredient within the vitreous chamber for up to 6 months after an intravitreal injection, allowing a prolonged interval of effica…
Elevated levels of anti-endotoxin antibodies in patients with bilateral idiopathic acute anterior uveitis
2010
. Purpose: Endotoxins have been proved to be responsible for acute anterior uveitis (AAU) in animals in a well-established experimental model of endotoxin-induced uveitis (EIU). The purpose of our study was the detection of antibodies against endotoxins of selected enterobacteria in the serum of patients with idiopathic AAU and searching for correlations between the levels of these antibodies and the presence of HLA-B27 antigen as well as characteristic signs of EIU such as bilaterality and the absence of spontaneous recurrences of the disease. Methods: Reactions of serum IgG antibodies with lipopolysaccharides (LPSs) of Escherichia coli O1, E. coli O10, E. coli O111, E. coli J5, and Kleb…
Metastatic Anterior Chamber Non-Hodgkin Lymphoma in a Patient With Acquired Immunodeficiency Syndrome
1997
Purpose To alert ophthalmologists to the possibility of metastatic anterior chamber intraocular non-Hodgkin lymphoma in patients with acquired immunodeficiency syndrome (AIDS). Methods We examined a 19-year-old man with AIDS who had an anterior uveitis with pseudohypopyon and a history of 2 months of malaise. A specimen of the lesion was obtained with a 25-gauge needle for pathologic examination. RESULTS: Systemic exploration showed hepatomegaly. Abdominal computed tomography showed multiple lesions in the liver and spleen. Fine-needle aspiration disclosed a high-grade non-Hodgkin lymphoma. The result of a fine-needle aspiration obtained from a lesion in the anterior chamber was consistent …
Specific association of IL17A genetic variants with panuveitis.
2015
Background/aims A pathogenic role of Th17 cells in uveitis has become clear in recent years. Therefore, in the present study, we aimed to evaluate the possible influence of the IL 17A locus on susceptibility to non-anterior uveitis and its main clinical subgroups. Methods Five IL17A polymorphisms (rs4711998, rs8193036, rs3819024, rs2275913 and rs7747909), selected by tagging, were genotyped using TagMan assays in 353 Spanish patients with non-anterior uveitis and 1851 ethnically matched controls. Results The case/control analysis yielded a consistent association between two of the analysed genetic variants, rs8193036 and rs2275913, and the presence of panuveitis under a dominant model (p(FD…
Clinical manifestations of Behçet's disease in 137 Italian patients: Results of a multicenter study
2005
Objective. To determine the type and frequency of clinical features of Behcets disease in a population of Italian patients. Methods. We retrospectively v studied 137 Italian patients (76 males and 61 females, age at onset 29.6 +/- 12.2 [mean +/-SD] Years) seen consecutively in nine different referral centers. The duration of follow-up (it study entry was 10.9 +/- 8.2 years. Virtually all patients fulfilled the classification criteria developed by the International Study Group for Behcets disease. The clinical manifestations of the patients were recorded by the attending physicians using specifically designed forms. \ Results. The most frequent manifestations at disease onset were oral (78.3…
Inflammation after sclerocorneal versus clear corneal tunnel phacoemulsification.
2000
Abstract Objective To compare the postoperative inflammation after phacoemulsification followed by intraocular lens (IOL) implantation by means of sclerocorneal versus clear corneal tunnel incision. Design Randomized controlled clinical trial. Participants One hundred eyes of 100 patients were examined at a German University eye hospital. Intervention One hundred eyes with cataract necessitating phacoemulsification with posterior chamber IOL implantation were randomly assigned to receive a temporal sclerocorneal or clear corneal tunnel incision by a single surgeon. Main outcome measures Preoperative and postoperative inflammation was evaluated by measurement of flare using laser flare photo…
Tubulointerstitielle-Nephritis-Uveitis-Syndrom (TINU-Syndrom)
1995
Abstract For 10 weeks a 25-year-old man had been suffering from tiredness, fatigue, nausea and a 16 kg weight loss. Erythrocyte sedimentation rate (83/133 mm), serum C-reactive protein (5.5 mg/dl) and creatinine (5.05 mg/dl) were all elevated. He also had proteinuria (1120 mg daily), sterile leukocytosis and a creatinine clearance of 10 ml/min. Renal biopsy showed interstitial nephritis and bone marrow biopsy revealed non-caseous epithelioid-cell granulomas. 14 days after admission he developed acute iritis in the right eye. Other causes having been excluded, the diagnosis of tubulo-intestinal nephritis with uveitis (TINU syndrome) was made. The clinical symptoms and laboratory findings imp…
