RESUMEN
OBJECTIVE: Anti-TNF-α agents have significantly changed the management of juvenile idiopathic arthritis (JIA). We evaluated the safety and efficacy of adalimumab (ADA) and infliximab (IFX) for the treatment of JIA-associated uveitis in patients treated for ≥ 2 years. METHODS: Patients with JIA-associated uveitis treated with IFX and ADA were managed by a standardized protocol and data were entered in the ORCHIDEA registry. At baseline, all patients were refractory to standard immunosuppressive treatment or were corticosteroid-dependent. Data recorded every 3 months were uveitis course, number/type of ocular flares and complications, drug-related adverse events (AE), and treatment switch or withdrawal. Data of patients treated for ≥ 2 years were analyzed by descriptive statistics. RESULTS: Up to December 2014, 154 patients with ≥ 24 months followup were included in the study. Fifty-nine patients were treated with IFX and 95 with ADA. Clinical remission, defined as the absence of flares for > 6 months on treatment, was achieved in 69 patients (44.8%), with a better remission rate for ADA (60.0%) as compared to IFX (20.3%; p < 0.001). A significant reduction of flares was observed in all patients without difference between the 2 treatment modalities. The number of new ocular complications decreased in both groups but was lower for ADA (p = 0.015). No serious AE were recorded; 16.4% of patients experienced 35 minor AE and the incidence rate was lower with ADA than with IFX. CONCLUSION: At the 2-year followup, ADA showed a better efficacy and safety profile than IFX for the treatment of refractory JIA-associated uveitis.

AIM: Oligoarticular onset juvenile idiopathic arthritis (oJIA) is characterised by a prevalent lower limb involvement, antinuclear antibodies (ANA) positivity and high risk of anterior uveitis. As we observed that oJIA patients frequently present with joint hypermobility (JH), we investigated whether there was a relationship between oJIA and JH. METHODS: Our series consisted of children with oJIA, as defined by the International League of Associations for Rheumatology criteria, for whom complete clinical data of at least 2 years' duration were available. Clinical and laboratory data, collected at disease onset and at the last follow-up, included: sex, age, presence of JH according to the Beighton score, disease activity, presence of uveitis, ANA, treatment and outcome. RESULTS: A total of 274 oligoarticular JIA patients (224 female, 50 male; mean age: 11.5) followed on average for 6.6 years, entered the study. The mean age at disease onset was 4.9 years, ANA were positive in 83.9% and uveitis occurred in 20.8%. JH was present in 70.8% of cases at onset, in 44.5% at the last evaluation. JH was more frequent in females (73.7%) than in males (58.0%) (P = 0.028). Uveitis was less frequent in hypermobile children both at diagnosis (17.5 vs. 28.7%, P = 0.037) and during overall disease course (23.7 vs. 36.3%, P = 0.034). Of 163 subjects with at least 5-year follow-up, the full clinical remission rate was significantly higher in JH patients (50.5%) than in those without JH (42.3%; P = 0.042). CONCLUSION: In patients with oligoarticular JIA, JH is more frequent than in healthy subjects, uveitis less frequent and the long-term outcome better.
