Uveitis is a sight-threatening primary intraocular inflammation of various origins in mainly young and active patients. Due to the absence of biomarkers in most of the cases, the current treatment of noninfectious entities remains nonspecific, using corticosteroids, conventional immunosuppressors, and more recently biological agents. Identification of regulatory T cells in different models of autoimmune uveitis together with the evaluation of this important subpopulation in different entities paved the way for new therapeutic strategies, in addition to exclusive pharmaceutical approaches. Upregulation of regulatory T cells induced by biological agents has been recently highlighted. Development of cell therapy in autoimmune diseases is at its stammering needing more experimental data and robust clinical trials to demonstrate safety and efficacy before larger developments. Specific or polyclonal Tregs may be used, but it is of utmost importance to determine the method of selection, the level of activation, and the route of administration. Mastering immune cell therapy remains a challenging goal in patients with autoimmune diseases, but it may significantly enlarge our therapeutic possibilities in severe and refractory situations.

To report long-term results of intravitreal (IVT) bevacizumab as first local treatment for choroidal neovascularization (CNV) secondary to uveitis. Files of patients receiving 1.25 mg/0.05 ml bevacizumab as primary local treatment for CNV were retrospectively reviewed. Main outcomes were change in best-corrected visual acuity (BCVA) and central foveolar thickness (CFT), treatment-related adverse events, and number and frequency of injections. Fifteen eyes from fifteen patients were included. Multifocal choroiditis and panuveitis were the diagnosis in seven, ampiginous choroiditis in two, and for six remaining, serpiginous choroiditis, sympathetic ophthalmia, Vogt-Koyanagi-Harada syndrome, punctuate inner choroidopathy, tuberculosis and idiopathic inflammation. In 13 eyes, neovascularization was subfoveal, and peripapillary in two. Intraocular inflammation was strictly controlled in all cases by the time of injections. BCVA improved from logMar 0.53 to logMar 0.29 in 12 eyes (80%), while CFT decreased from 239.06 to 195.2 μm in 13 (87%). Twelve eyes received more than one injection; mean number in this group was 4.25 (2-8), and frequency 1 every 12.97 weeks. There were no adverse events related to bevacizumab or the procedure. Median follow-up was 17.6 months (8-25). First-intention IVT bevacizumab for inflammatory CNV showed transient improvement in BCVA and CFT, in eyes under controlled inflammation. Reinjection was needed in most cases. Further work should conclude about safety related to repeated injections. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the efficacy of interferon alfa-2a (IFN alfa) in severe uveitis associated with Behçet's disease, that is refractory to steroids and conventional immunosuppressive agents.Patients and Methods: Patients with Behçet's disease (according to the International Study Group criteria), who relapsed despite steroids and immunosuppressive agents, were included in this retrospective study. Ophthalmological examination, laser flare photometry, and fluorescein angiography associated with laboratory tests were performed at regular intervals. IFN alfa (3 millions units thrice a week) was injected subcutaneously.Results: Eight patients (sex ratio: 1) were included between May 1995 and January 1999. The mean age was 29.1 years (14-54 years) and the disease was present between 11 and 167 months before the administration of IFN alfa. IFN alfa was efficient in all cases with a mean follow-up of 22 months (10-55 months). Steroids were tapered from a mean dosage of 47 mg/d to a mean dosage of 8.5 mg/d. Ocular inflammation was controlled and visual acuity improved in all cases. Treatment was generally well tolerated despite a constant but transient flu-like syndrome. IFN alfa was tapered in three patients and stopped in one case without any relapse after five months.Conclusions: Within the limitations of this retrospective study, low-dose IFN alfa seems to be well tolerated, promising in the management of refractory forms of uveitis due to Behçet's disease, and effective in allowing a reduction of steroid dosage. A prospective controlled study is necessary to confirm these preliminary results. [ABSTRACT FROM AUTHOR]
