Abstract: OBJECTIVE: To investigate the efficacy and safety of a combination therapy with methotrexate (MTX) and cyclosporine A (CyA) in patients with juvenile idiopathic arthritis (JIA) who were refractory to MTX as a single second-line agent. METHODS: Seventeen consecutive patients with JIA who had refractory polyarthritis despite a minimum of 6 months of MTX as a single second-line agent at the dose of 15 to 25 mg/m2/week were continued with MTX with the addition of CyA (4 mg/kg/day) for 6 to 30 months (median 10 months) were analyzed. The clinical response to therapy was assessed through the preliminary definition of improvement in JIA. RESULTS: At the end of the treatment, as compared to the time when CyA was added to MTX, 8 patients (47%) met the 30% definition of improvement; among them 5 (29%) met the 70% definition of improvement, and 2 (12%) achieved complete disease control. Seven patients (41%) experienced side effects: 4 gastrointestinal discomfort, 1 liver transaminase elevation, and 2 increase > or = 30% in the serum creatinine concentration. No patients was discontinued from combination therapy due to adverse events. CONCLUSION: In our JIA patients who were refractory to MTX as a single second-line agent, the addition of CyA was associated with a significant clinical improvement in roughly half of the patients.

Abstract: OBJECTIVE: To investigate whether the achievement of inactive disease in the first 5 years predicts a more favorable outcome of children with juvenile idiopathic arthritis (JIA). METHODS: We reviewed clinical charts of 123 patients who started taking methotrexate, were followed for at least 5 years, and received a yearly assessment in the first 5 years. At each yearly visit, the presence of inactive disease was assessed. Patients were divided into 3 groups: (1) patients who never reached inactive disease; (2) patients who reached inactive disease in only 1 visit; and (3) patients who reached inactive disease in > or = 2 visits. Outcome was evaluated after 6 to 18 years (median 7.1 yrs) by assessing the following clinical measures: restricted joint count, Childhood Health Assessment Questionnaire (CHAQ), Juvenile Arthritis Damage Index (JADI), and Poznanski score of radiographic damage. RESULTS: In the first 5 years, 62 patients (50.4%) were noted to have active disease at their yearly visit, 40 patients (32.5%) were noted to have inactive disease only once, and 21 patients (17.1%) were noted to have inactive disease in > or = 2 visits. Patients who achieved inactive disease 1 or more times had lower restricted joint count (p = 0.007) and JADI-Articular score (p = 0.004) at last followup visit than those who never reached such a state. A similar trend, although not significant, was observed for CHAQ and Poznanski score of radiographic damage. CONCLUSION: Attainment of the state of inactive disease at least once in the first 5 years was found to be associated with less longterm joint damage and with a trend toward less functional impairment.

Abstract: OBJECTIVE: To investigate the rate of radiographic progression, as measured with the carpo-metacarpal ratio (Poznanski score), during etanercept (ETN) therapy in children with polyarticular juvenile idiopathic arthritis (JIA). METHODS: Patients included in the Italian ETN registry who had a standard radiograph of both hands and wrists in the posteroanterior view made at start of treatment and after 1 year were included in the study. The clinical response was assessed by means of the ACR Pediatric definition of improvement. Radiographic progression was determined by calculating the change in the Poznanski score between the baseline and the 1-year radiographs. RESULTS: A total of 40 patients were studied. The frequency of ACR pediatric 30, 50, and 70 response at 1 year was 77%, 72%, and 50%, respectively. The median change in the Poznanski score between baseline and 1 year was + 0.3 units, meaning that, on average, patients experienced improvement in radiographic progression. CONCLUSION: Our pilot study provides evidence that ETN is potentially capable of reducing the progression of radiographic joint damage in JIA. This finding deserves confirmation in a controlled trial.

Abstract: OBJECTIVE: To develop adapted versions of the Sharp/van der Heijde radiographic scoring system for use in juvenile idiopathic arthritis (JIA), and to investigate their validity in JIA patients with polyarticular disease. METHODS: The study group comprised 177 patients with polyarticular JIA. Radiographs of the wrist/hand of each patient were obtained at baseline (first observation) and then at 1, 3, 5, 7/8, and 10 years and were assessed independently by 2 pediatric rheumatologists according to different adaptations of the Sharp/van der Heijde method. To facilitate score assignment, the radiograph for each patient was compared with a bone age-related standard. Validation procedures included analysis of reliability, construct validity, and score progression over time. RESULTS: Interobserver and intraobserver agreement on longitudinal score values and score changes was good for all of the adapted scoring versions (intraclass correlation coefficient >0.85). Score changes over time were moderately to strongly correlated with the clinical indicators of long-term joint damage and with the amount of long-term radiographic damage as measured with the carpo:metacarpal ratio, thereby demonstrating good construct validity. A steady increase in scores over time was observed, with joint space narrowing being the most common form of damage throughout the disease course. The inclusion of 5 new areas appeared to increase the overall construct validity of erosion scores. CONCLUSION: Our results show that the adapted versions of the Sharp/van der Heijde score are reliable and valid for the assessment of radiographic progression in patients with JIA.

Abstract: OBJECTIVES: Recent laboratory and clinical data suggest that two prototype autoimmune diseases, systemic lupus erythematosus and rheumatoid arthritis are mainly driven by distinct cytokines, interferon (IFN)-alpha and tumour necrosis factor (TNF)-alpha, respectively. We here investigated the presence and characteristics of natural type I IFN-producing cells (IPCs), as well as IFN-alpha and TNF-alpha expression at sites of inflammation in juvenile idiopathic arthritis (JIA). METHODS: Peripheral blood (PB) and synovial fluid (SF) mononuclear cells (MNCs) (n = 25 each) from JIA patients with active disease were studied. IPCs were identified as BCDA-2(+)CD123(+)HLA-DR(+)CD45RA(+) cells, and dendritic cells (DCs) as CD11c(+)CD14(-/low)lin(-) cells by flow cytometry. IPCs and DCs were analysed for Toll-like receptor-7 and -9 mRNA expression by real-time polymerase chain reaction. IFN-alpha was measured by enzyme-linked immunosorbent assay in serum, SF and in supernatants of influenza virus-infected, cultured IPCs. Synovial tissues of n = 6 additional JIA patients were analysed by immunohistochemistry using mAbs against CD123, IFN-alpha, TNF-alpha, CD3, CD19 and CD138. RESULTS: IPCs were enriched in SF MNCs compared with PB MNCs in all JIA patients. Influenza-induced, but no spontaneous IFN-alpha release was detected from SF IPCs, and serum and SF IFN-alpha levels were not elevated. Nonetheless, in synovial tissue IFN-alpha producing cells accumulated at inflammatory lymph-follicular-like structures, while TNF-alpha producing cells were mostly found at the lining and sublining layers. CONCLUSIONS: These data suggest that besides TNF-alpha-expressing cells, IFN-alpha-producing IPCs are involved in initiation, maintenance or regulation of the inflammatory response in JIA.

Abstract: OBJECTIVE: To investigate the applicability of the Sharp and Larsen scoring methods for radiographic damage in juvenile idiopathic arthritis (JIA). METHODS: Wrist/hand radiographs of 25 patients with polyarthritis obtained at first observation and then yearly for 4-5 years were assessed independently by 2 pediatric rheumatologists according to the Sharp and Larsen methods. To facilitate score assignment, each patient radiograph was compared with a bone age-related standard. A third pediatric rheumatologist measured the Poznanski score, and a pediatric radiologist provided a semiquantitative assessment of radiographic damage severity. RESULTS: Interobserver and intraobserver agreement on longitudinal scores were good for both Sharp and Larsen methods, with intraclass correlation coefficient >0.9. Agreement on change assessment was good for the Sharp method and moderate for the Larsen method. Both methods yielded a steady increase in scores during the study, with score change being more marked in the first year. Sharp and Larsen scores were highly correlated (r(s) = 0.96). Correlations of both scores with the Poznanski score were moderate to high (r(s) from -0.62 to -0.72). Radiologist score was correlated at borderline-high level with both Sharp (r(s) = 0.70) and Larsen (r(s) = 0.71) scores. Sharp and Larsen score change from baseline to final visit was moderately to highly correlated with the number of joints with active arthritis and restricted motion and the Childhood Health Assessment Questionnaire score at final visit. CONCLUSION: Our results demonstrate that the Sharp and Larsen scoring systems are potentially reliable and valid for assessment of radiographic progression in patients with polyarticular JIA.

Abstract: OBJECTIVE: The aim of the study was to evaluate the pattern of the lymphoid organization in the synovial tissue of patients affected with juvenile idiopathic arthritis (JIA). METHODS: A total of 40 JIA patients who underwent synoviectomy or synovial biopsies were enrolled. The mean age at surgery was 15.1 yrs (range 6-30 yrs) and the mean disease duration was 6.7 yrs (range 3 months to 22.2 yrs). Tissue specimens were grouped according to the following criteria: (i) diffuse perivascular infiltrate without lymphoid organization, (ii) T cell-B cell aggregates with or without germinal centre reaction. RESULTS: Synovial tissues from 12 JIA patients did not show any sign of lymphoid organization, whereas 28 patients displayed a variable number of T-B cell aggregates. Typical features consistent with a germinal centre reaction were present in two JIA patients only. Lymphoid organization in JIA patients did not correlate with the duration and severity of the disease or with the degree of synovial inflammation, but did positively correlate with the presence of anti-nuclear antibodies. Moreover, a diffuse lymphocyte infiltration was significantly related to the presence of an acute phase of inflammation and the presence of lymphoid aggregates correlated with the degree of plasma cells infiltration. CONCLUSIONS: Lymphoid neogenesis in JIA represents a phase in the immunopathological process that characterize the development of inflammatory synovitis. It is not related to disease activity or severity, but appears to be more frequent in patients with circulating anti-nuclear antibodies.

Abstract: OBJECTIVE: To evaluate immunological safety and immunogenicity of influenza vaccine administration in patients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). PATIENTS AND METHODS: Twenty-four patients with low and/or stable disease activity 14 with SLE (mean age 43.42+/-12.18 years; 13 women) and 10 with RA (mean age 51+/-14.57 years; 9 women), diagnosed on the basis of the American College of Rheumatology criteria, have been immunized with trivalent split influenza vaccine without adjuvant. Further 24 non-vaccinated patients, 14 with SLE and 10 with RA, and 10 vaccinated healthy subjects, all age- and sex-matched, were used as controls. The patients underwent clinical and laboratory (specific anti-influenzavirus antibodies, auto-antibodies, peripheral blood lymphocyte subpopulations) evaluation before and 30 days after vaccination; auto-antibodies were also assessed at 90 days and disease activity at 90 and 180 days. RESULTS: The specific antibody response towards the three used antigens (A/New Caledonia/20/99, A/Moscow/10/99, and B/Shangdong/7/97) significantly increased in both patients and healthy controls, without any significant difference between them. No significant difference could instead be observed on the clinical activity, auto-antibodies, and peripheral blood lymphocyte subpopulations before and after vaccination, and between patients and controls. CONCLUSIONS: Trivalent split influenza vaccine without adjuvant seems to be safe and immunogenic in patients with SLE and RA, provided that only patients with low and/or stable disease activity are selected.

Abstract: OBJECTIVE: To develop and validate a clinical measure of articular and extraarticular damage in patients with juvenile idiopathic arthritis (JIA). METHODS: The Juvenile Arthritis Damage Index (JADI), which is derived from physical examination and a brief review of the patient's clinical history, is composed of 2 parts: assessments of articular damage (JADI-A) and extraarticular damage (JADI-E). Instrument validation was accomplished by evaluating 158 JIA patients with disease duration of at least 5 years, seen consecutively over 21 months. The instrument's feasibility, face and content validity, construct and discriminative ability, internal consistency, and interrater reliability were examined. RESULTS: Among the 158 JIA patients, 47% and 37% had articular and extraarticular damage, respectively. The JADI was found to be feasible and to possess both face and content validity. The JADI-A score correlated highly with the number of joints with limited range of motion (Spearman's r [r(S)] = 0.72) and correlated moderately with the Childhood Health Assessment Questionnaire score (r(S) = 0.41), Steinbrocker functional classification (r(S) = 0.50), and Poznanski's score of radiographic damage (r(S) = -0.54), thereby demonstrating good construct validity. Correlations with the JADI-E score were lower, owing to the heterogeneity of its items. The JADI-A discriminated well among different levels of disability. The internal consistency (Chronbach's alpha) of the JADI-A and JADI-E was 0.93 and 0.59, respectively. The intraclass correlation coefficients between pairs of independent observers ranged from 0.85 to 0.97. CONCLUSION: The JADI exhibited good reliability, construct validity, and discriminative ability and is therefore a valid instrument for the assessment of long-term damage in patients with JIA, in the context of both clinical management and research settings.

Abstract: OBJECTIVE: To describe the clinical and radiographic features of a group of juvenile idiopathic arthritis (JIA) patients who developed unilateral destructive wrist synovitis. METHODS: All wrist radiographs performed yearly between 1986 and 2002 in JIA patients who had wrist involvement were retrospectively reviewed to identify patients who had unilateral erosive wrist synovitis, defined as a difference of at least -3 units in the Poznanski score between the affected wrist and the unaffected wrist, with the Poznanski score in the unaffected wrist being > -2 units throughout the follow-up period. Clinical and radiographic data obtained during follow-up were recorded for all patients. RESULTS: Of a total of 250 patients for whom we had approximately 900 wrist radiographs, 6 patients were found to have unilateral erosive wrist synovitis. The JIA onset subtype was oligoarticular in 5 patients and polyarticular in 1 patient and the disease duration from presentation to the last follow-up visit ranged from 2 to 16 years. The arthritis course was polyarticular in all patients. Five patients had positive antinuclear antibodies (ANA) and 1 had positive rheumatoid factor (RF). At the last follow-up visit, all patients had some impairment of wrist function and 2 patients had wrist subluxation. There was a marked radiographic damage in all affected wrist, with the Poznanski ranging from -8.0 to -8.50 units in 3 patients and being -5.5, -3.1 and -2.4 units, respectively, in 3 patients. The severity of radiographic damage in the ANA-positive patients with the longest disease duration was comparable to that observed in the RF-positive patient. CONCLUSION: Unilateral erosive wrist synovitis seems to be uncommon in JIA. Patients with unilateral wrist synovitis may be at risk of a destructive course irrespective of the JIA onset subtype.

Abstract: OBJECTIVE: To investigate the rate of radiographic progression and identify prognostic factors of radiographic progression, radiographic damage, and physical disability in juvenile idiopathic arthritis (JIA). METHODS: Ninety-four JIA patients with a median disease duration of 1.1 years were followed up prospectively for a median of 4.5 years. Bilateral wrist radiographs were obtained at baseline, at 1 year, and at the last followup visit. Radiographic damage was assessed by the carpal length (Poznanski score), and physical disability by the Childhood Health Assessment Questionnaire (C-HAQ). Yearly radiographic progression, the Poznanski score at the final visit, and the C-HAQ score at the final visit were used as outcome measures. Baseline parameters included demographic, clinical, laboratory, and radiographic data. RESULTS: The mean +/- SD Poznanski score was -1.2 +/- 1.3 at baseline, -1.7 +/- 1.8 at the 1-year visit, and -1.9 +/- 2.2 at the final visit (P < 0.0001). Radiographic progression was greater during the first year (mean +/- SD -0.5 +/- 1.1) than between the 1-year visit and the final visit (-0.2 +/- 1.3). The mean yearly radiographic progression during the entire study period was -0.1 +/- 0.4. Logistic regression analysis revealed that radiographic progression during the first year was the only baseline parameter that was predictive of all 3 study outcomes. The final Poznanski score was also predicted by the baseline Poznanski score, whereas female sex was protective against radiographic progression. CONCLUSION: We identified the prognostic factors for poorer outcome in polyarticular-course JIA. The changes in the early Poznanski score can be used to predict long-term joint damage and physical disability.

Abstract: OBJECTIVE: To address the functional and prognostic relevance of the -173 single-nucleotide G-to-C polymorphism of the macrophage migration inhibitory factor (MIF) gene in patients with systemic-onset juvenile idiopathic arthritis (systemic-onset JIA) by evaluating its association with serum and synovial fluid levels of MIF, with glucocorticoid requirement, and with the outcome of the disease. METHODS: A total of 136 patients with systemic-onset JIA were studied, including 98 patients from the British Paediatric Rheumatology Study Group's National Repository for JIA and 38 patients who were followed up at the IRCCS Policlinico San Matteo (Pavia, Italy) and the IRCCS G. Gaslini (Genoa, Italy). The MIF-173 polymorphism was genotyped using SnaPshot ddNTP primer extension and capillary electrophoresis. MIF levels were measured by enzyme-linked immunosorbent assay. The evaluation of the association of the MIF-173 polymorphism with outcome was performed only in Italian patients who were followed up for >5 years, by analyzing retrospectively 1) the number of joints with active arthritis and the number of joints with limited range of motion; 2) the score, at the last visit, on the Italian version of the Childhood Health Assessment Questionnaire (C-HAQ); and 3) data concerning the treatment regimens during the disease course. RESULTS: Systemic-onset JIA patients carrying a MIF-173*C allele had serum and synovial fluid levels of MIF significantly higher than those in patients with the GG genotype. The duration of glucocorticoid treatment on a daily regimen was significantly longer in patients carrying a MIF-173*C allele than in MIF-173 GG homozygous patients. Moreover, the duration of clinical response to intraarticular injection of triamcinolone hexacetonide was significantly shorter in patients carrying a MIF-173*C allele. At the last visit, the numbers of joints with active arthritis, the C-HAQ scores, and the numbers of joints with limited range of motion were significantly higher in patients carrying the MIF-173*C allele. CONCLUSION: Our study shows the functional relevance of the MIF-173 polymorphism and suggests that the MIF-173*C allele is a predictor of poor outcome in systemic-onset JIA.
