Abstract: The objective was to estimate the incidence of serious infections in the patients treated with anti-TNFalpha agents for rheumatoid arthritis (RA) recorded in the Lombardy Rheumatology Network (LORHEN) registry. The study inclusion criteria were met by 1064 of the 1114 patients with long-standing RA, 519 treated with infliximab, 303 with adalimumab, and 242 with etanercept; their mean age was 55.8 years and the mean duration of RA 9.4 years. Seventy-three patients (6.9%) experienced a total of 74 serious infections, an incidence rate for all treatment courses of 35.9 per 1000 patient-years (95% confidence interval [95% CI] 27.66-44.13). Most were lower respiratory tract (34.2%) or skin and soft tissue infections (20.5%). Of the 1064 patients, the 790 treated with anti-TNFalpha after March 2002 underwent screening tests for LTBI; five patients developed active tuberculosis. Three patients died of septic shock. The type of anti-TNFalpha agent did not seem to affect the incidence or site of the infections. Both univariate and multivariate analyses identified age at the start of anti-TNFalpha treatment (p=0.008), baseline erythrocyte sedimentation rate ([ESR] p=0.014), and the concomitant use of corticosteroids (p=0.029) as significant predictors of infections. There was no statistically significant difference in risk between the anti-TNFalpha agents.

Abstract: OBJECTIVE: There are no validated criteria to evaluate clinical response in juvenile idiopathic arthritis (JIA). The purpose of this study was to compare 4 sets of criteria (2 from the American College of Rheumatology [ACR] and 2 from the European League Against Rheumatism [EULAR]) for clinical response evaluation in JIA patients treated with methotrexate and/or anti-tumor necrosis factor alpha drugs. METHODS: Seventy-five patients with JIA were evaluated at baseline and after 6 months of therapy with second-line drugs. Mean age at study onset was 12.8 years (range 2-32.9 years). Diagnoses were systemic JIA (n = 16), rheumatoid factor-positive JIA (n = 5), rheumatoid factor-negative JIA (n = 9), persistent oligoarticular JIA (n = 10), extended oligoarticular JIA (n = 33), and psoriatic arthritis (n = 2). Clinical response was evaluated with the ACR Pediatric 30 criteria and the ACR 20% response criteria (ACR20), and with the EULAR Disease Activity Score (DAS) and 28-joint DAS (DAS28). Patients with EULAR criteria responses of "good" or "moderate" were classified as responders. Responders and nonresponders according to the different criteria were then compared. RESULTS: For patients younger than 16 years, Cohen's kappa varied between 0.51 and 0.72, with a good-to-excellent reproducibility index for all comparisons, except for the DAS28/ACR20 comparison. The best agreement was obtained by comparing the DAS and the ACR Pediatric 30. For patients older than 16 years, the reproducibility index was good or excellent in only 2 cases, i.e., comparing the DAS and the ACR Pediatric 30 and comparing the DAS and the DAS28 (as expected). CONCLUSION: Our study shows a good agreement overall for the different criteria tested. The highest concordance was observed between the DAS and the ACR Pediatric 30, the lowest between the DAS28 and the ACR20. Our data suggest that the ACR Pediatric 30 criteria can be used also in adult patients affected by JIA, and that the original DAS can be an alternative to the ACR Pediatric 30 in both children and young adults with JIA.

Abstract: OBJECTIVE: To evaluate the efficacy and safety of a chimeric monoclonal anti-tumor necrosis factor alpha antibody (infliximab) with methotrexate (MTX) in juvenile idiopathic arthritis (JIA) with an active polyarticular course that is not responsive to MTX. METHODS: Twenty-four young adults with long-lasting, refractory JIA were enrolled in an open, prospective, 2-year pilot study. Patients received intravenous infliximab at 3 mg/kg of body weight at weeks 0, 2, and 6 and every 8 weeks thereafter, with weekly subcutaneous MTX. RESULTS: The median duration of therapy was 9.1 months. Significant improvements were observed in the number of joints (28-joint count) with active disease (median 6 at baseline, 2 at 2 weeks, 0 at 6 months, 0 at 1 year; P < 0.05). Pain as well as patient's and physician's global assessments of disease status were assessed on 0-100-mm (0 = best; 100 = worst) visual analog scales (VAS). There were significant improvements in VAS pain scores (45 at baseline, 25 at 2 weeks, 8.5 at 6 months, 10 at 1 year; P < 0.05), patient's global assessment of disease status (50 at baseline, 22 at 2 weeks, 11.5 at 6 months, 18 at 1 year; P < 0.05), and physician's global assessment of disease status (50.5 at baseline, 22.5 at 2 weeks, 6.5 at 6 months, 10 at 1 year; P < 0.01). In addition, there were significant improvements in the erythrocyte sedimentation rate (64 mm/hour at baseline, 36 mm/hour at 2 weeks, 23.5 mm/hour at 6 months, 35 mm/hour at 1 year; P < 0.01) and C-reactive protein level (4.9 mg/dl at baseline, 2.8 mg/dl at 2 weeks, 3.1 mg/dl at 6 months, 3.2 mg/dl at 1 year; P < 0.005). The percentage of patients meeting the American College of Rheumatology 20% improvement criteria at each assessment ranged from 54.2% to 86.7%. Of the responses on the Disease Activity Score in 28 joints, 37.5-63.6% were classified as "good," 14.3-33.3% were classified as "moderate," and 18-37.5% were classified as "no response." Twelve patients (50%) had adverse events, and 5 patients (20.8%) withdrew. CONCLUSION: Infliximab plus MTX showed high effectiveness and safety in short- and medium-term treatment of long-lasting refractory JIA. A controlled multicenter clinical trial is needed.
