TCZ appears to be a useful therapy for severe refractory JIA-associated uveitis.

ABSTRACT.Purpose: To report the anatomical pattern and etiological spectrum of uveitis in an urban multi-ethnic population from Barcelona, Spain. General and specific epidemiological data for the most prevalent aetiologies are also calculated. Methods: A cross-sectional study of consecutive uveitis cases was performed between 1 January 2009 and 31 December 2012. Exogenous endophthalmitis, surgery-related, post-traumatic and toxic uveitis along with masquerade syndromes were excluded. Anatomical (Standard Uveitis Nomenclature criteria) and aetiological patterns (by tailored tests), age, sex, geographical origin and laterality were analysed. Mean incidence and prevalence were calculated for a mid-period reference population. Results: From 1022 patients included, 52% were anterior uveitis (AU), 23% posterior, 15% panuveitis and 9% intermediate uveitis. Aetiologically, 26% were unclassifiable, 29% infectious, 25% associated with systemic immune diseases, and 20% corresponded to ocular-specific syndromes. Among classified causes, herpesvirus (12%), toxoplasma (7%), Behc ßet's disease (BD) (5%), HLA-B27-isolated AU (5%), ankylosing spondylitis (5%), tuberculosis-related uveitis (TRU) (5%), birdshot chorioretinopathy (3%) and sarcoidosis (3%) were the most frequent. Non-Spanish origin was recorded in 22%, with 47% of VogtKoyanagi-Harada and 36% of toxoplasma cases coming from South America, 10% of BD and 11% of TRU from Africa and 24% of TRU cases from Asia. A mean annual incidence of 51.91 cases/100 000 inhabitants was found for the referral population. Conclusion: In our referral area, 74% of the uveitis cases can be correctly classified. A large myriad of uveitis aetiologies with a strong geographical origin burden are found in Western urban multi-ethnic populations.

Objective. To investigate the role of rheumatoid factor (RF) status and anti-citrullinated peptide antibody (ACPA) status as predictors of abatacept (ABA) effectiveness in patients with rheumatoid arthritis (RA).Methods. We conducted a pooled analysis of data from 9 observational RA registries in Europe (ARTIS [Sweden] [Switzerland]). Inclusion criteria were a diagnosis of RA, initiation of ABA treatment, and available information on RF and/or ACPA status. The primary end point was continuation of ABA treatment. Secondary end points were ABA discontinuation for ineffectiveness or adverse events and response rates at 1 year (good or moderate response according to the European League Against Rheumatism criteria with LUNDEX adjustment for treatment continuation). Hazard ratios (HRs) and 95% confidence intervals (95% CIs) for the study end points in relation to RF and ACPA status were calculated.Results. We identified 2,942 patients with available data on RA-associated autoantibodies; data on RF status were available for 2,787 patients (77.0% of whom were RF positive), and data on ACPA status were available for 1,903 patients (71.3% of whom were ACPA positive). Even after adjustment for sociodemographic and disease-and treatment-related confounders, RF and ACPA positivity were each associated with a lower risk of ABA discontinuation for any reason .90], P < 0.001 and HR 0.78 [95% CI 0.68-0.90], P < 0.001, respectively), compared to RF-negative and ACPA-negative patients. Similar associations with RF and ACPA were observed for discontinuation of ABA treatment due to ineffectiveness, with HRs of 0.72 (95% CI 0.61-0.84) and 0.74 (95% CI 0.62-0.88), respectively (both P < 0.001).Conclusion. Our results strongly suggest that positivity for RF or ACPA is associated with better effectiveness of ABA therapy.

Cystoid macular edema (CME) is a leading cause of blindness. In this study we assessed the efficacy and safety of Tocilizumab (TCZ) in refractory CME. DESIGN: Retrospective case series. METHODS: Patients with CME secondary to non-infectious uveitis who had inadequate response to corticosteroids and at least one conventional immunosuppressive drug, and in most cases to other biological agents were studied. CME was defined as central retinal thickness greater than 300 µm. The primary outcome measure was macular thickness. Intraocular inflammation, best corrected visual acuity (BCVA), and corticosteroid-sparing effect were also analyzed. RESULTS: A total of 25 patients (mean± SD age 33.6±18.9 years; 17 women) with CME were assessed. Underlying diseases associated with uveitis-related CME are juvenile idiopathic arthritis (n=9), Behçet's disease (n=7), birdshot retinochoroidopathy (n=4), idiopathic (n=4), and sarcoidosis (n=1). The ocular patterns were panuveitis (n=9), anterior uveitis (n=7), posterior uveitis (n=5) and intermediate uveitis (n=4). Most patients had CME in both eyes (n=24). TCZ was used in monotherapy (n=11) or combined with conventional immunosuppressive drugs. Regardless of the underlying disease, compared to baseline, a statistically significant improvement in macular thickness (415.7±177.2 vs 259.1±499.5 microns; p=0.00009) and BCVA (0.39±0.31 vs 0.54±0.33; p =0.0002) was obtained, allowing us to reduce the daily dose of prednisone (15.9±13.6 mg/day vs 3.1±2.3 p=0.002) after 12 months of therapy. Remission was achieved in 14 patients. Only minor side effects were observed after a mean follow up of 12.7±8.34 months. CONCLUSION: Macular thickness is reduced following administration of TCZ in refractory uveitis-related CME.
