Abstract: OBJECTIVE: To investigate the clinical use patterns, clinical effect and safety of cyclosporine A (CSA) in juvenile idiopathic arthritis (JIA) in the setting of routine clinical care. METHODS: An open-ended, phase IV post marketing surveillance study was conducted among members of the Pediatric Rheumatology Collaborative Study Group (PRCSG) and of the Paediatric Rheumatology International Trials Organisation (PRINTO) to identify patients with polyarticular course JIA who had received CSA during the course of their disease. RESULTS: A total of 329 patients, half of whom had systemic JIA, were collected in 21 countries. Data were collected during 1240 routine clinic visits. CSA was started at a mean of 5.8 years after disease onset and was given at a mean dose of 3.4 mg/kg/day. The drug was administered in combination with MTX in 61% and along with prednisone in 65% of the patients who were still receiving CSA. Among patients who were still receiving CSA therapy at the last reported visit, remission was documented in 9% of the patients, whereas in 61% of the patients the disease activity was rated as moderate or severe. The most frequent reason for discontinuation of CSA was insufficient therapeutic effect (61% of the patients); only 10% of the patients stopped CSA because of remission. In 17% of the patients, side effects of therapy was given as the primary reason for discontinuation. CONCLUSION: This survey suggests that CSA may have a less favourable efficacy profile than MTX and etanercept, whereas the frequency of side effects may be similar. The exact place of CSA in the treatment of JIA can only be established via controlled clinical trial.

Abstract: OBJECTIVE: To develop and validate a composite disease activity score for juvenile idiopathic arthritis (JIA), the Juvenile Arthritis Disease Activity Score (JADAS). METHODS: The JADAS includes 4 measures: physician global assessment of disease activity, parent/patient global assessment of well-being, active joint count, and erythrocyte sedimentation rate. These variables are part of the American College of Rheumatology (ACR) Pediatric 30 (Pedi 30), Pedi 50, and Pedi 70 criteria for improvement. Validation analyses were conducted on >4,500 patients and included assessment of construct validity, discriminant validity, and responsiveness to change. Three versions of the JADAS were tested based on 71-joint (range 0-101), 27-joint (range 0-57), or 10-joint (range 0-40) counts. Statistical performances of the JADAS were compared with those of 2 rheumatoid arthritis composite scores, the Disease Activity Score in 28 joints (DAS28) and the Clinical Disease Activity Index (CDAI). RESULTS: The JADAS demonstrated good construct validity, yielding strong correlations with JIA activity measures not included in the score and moderate correlations with the Childhood Health Assessment Questionnaire. Correlations obtained for the 3 JADAS versions were comparable, but superior to those yielded by the DAS28 and CDAI. The area under the curve of the JADAS predicted long-term disease outcome, measured as radiographic progression over 3 years. In 2 clinical trials, the JADAS discriminated well between ACR Pedi 30, Pedi 50, and Pedi 70 response and revealed strong responsiveness to clinical change. CONCLUSION: The JADAS was found to be a valid instrument for assessment of disease activity in JIA and is potentially applicable in standard clinical care, observational studies, and clinical trials.

Abstract: OBJECTIVE: To develop and test reduced joint counts in children with juvenile idiopathic arthritis (JIA). METHODS: Four reduced joint counts including 45, 35, 27, and 10 joints were devised by a panel of experienced pediatric rheumatologists, who selected the joints to be included based on the ease of technical assessment, functional relevance, and frequency of involvement. Three large samples of patients with JIA (total n=4353) who had a detailed joint assessment available were used to develop and test reduced joint counts. Performance of reduced counts was examined by comparing their Spearman correlation with the standard (i.e., complete) joint count. Construct validity was evaluated by calculating Spearman correlation with other JIA outcome measures. Responsiveness to clinical change was determined through the standardized response mean (SRM). RESULTS: Spearman correlations of reduced joint counts with the whole joint count and with the other JIA outcome measures were comparable, revealing that they had similar ability to serve as surrogate for the whole joint count and construct validity. Responsiveness to clinical change was also comparable across reduced counts (SRM 0.83-1.09 for active joint counts and 0.63-0.81 for restricted joint counts). Based on these results and considering the relative feasibility of the different counts, the 27-joint reduced count is proposed for use in JIA. This joint count includes the cervical spine and the elbow, wrist, metacarpophalangeal (from first to third), proximal interphalangeal, hip, knee, and ankle joints. CONCLUSION: Reduced joint counts appear to be as reliable as standard joint counts in assessment of the severity of joint disease and its change over time in children with JIA.

Abstract: OBJECTIVE: To compare magnetic resonance imaging (MRI), conventional radiography, and ultrasonography in identifying bone erosions in patients with juvenile idiopathic arthritis (JIA), and to determine the validity and reliability of an MRI scale in detecting and grading joint damage. METHODS: In 26 JIA patients, the clinically more affected wrist was studied with MRI, radiography, and ultrasonography, coupled with standard clinical assessment and biochemical analysis. MR images were assessed independently by 2 readers according to an apposite devised scoring system. RESULTS: Of 26 patients, 25 (96.1%) had 1 or more erosions as detected by MRI, whereas conventional radiography and ultrasonography revealed erosions in 13 (50%) of 26 and 12 (50%) of 24 patients, respectively. The ability of MRI to detect erosive changes was significantly higher with respect to conventional radiography (P = 0.002 with Bonferroni correction [P(B)]) and ultrasonography (P(B) = 0.0002) in the group of patients with <3 years' disease duration. Ultrasonography and conventional radiography were of equivalent value for the detection of destructive changes. Wrist MRI score correlated highly with radiographic erosion score (r(s) = 0.82) and with wrist limited range of motion score (r(s) = 0.69). The interreader intraclass correlation coefficient (ICC) for MRI score was excellent (0.97); intrareader ICCs were good for both investigators (0.97 and 0.79). CONCLUSION: MRI seems to be a powerful tool to detect early structural damage in JIA. The proposed MRI scale for bone erosions appears promising in terms of reliability and construct validity. The pathophysiologic meaning and the prognostic value of bone erosions revealed only by MRI remain to be established in longitudinal studies.

Abstract: OBJECTIVE: To investigate discrepancies between physicians' and parents' ratings of inactive disease in children with juvenile idiopathic arthritis (JIA) and the determinants of the discrepancy. METHODS: Study data were obtained from the clinical database generated at the study unit. Each patient visit included a standardized assessment of JIA outcome measures. One visit for each patient was selected for analysis. Three definitions of inactive disease were applied to the data: a physician-based definition (physician global assessment = 0); a parent-based definition (parent global assessment = 0); and a formal definition, based on fulfillment of newly developed criteria for inactive disease in JIA. RESULTS: Of 1237 visits made by 537 patients that included both physician and parent global assessments, 265 fulfilled the physician-based definition and/or the parent-based definition of inactive disease. Concordance between physicians and parents in rating the disease as inactive was seen in 40% of the visits, whereas in 60% of visits the 2 assessments were discordant. Parents tended to disagree with physicians in rating the disease as inactive if the child had pain or functional impairment, whereas physicians tended to disagree with parents in the presence of active joint symptoms. Only 2/3 of the 79 visits that fulfilled the formal definition of inactive disease also met the parent-based definition of inactive disease. CONCLUSION: We found frequent discordance between physicians' and parents' ratings of inactive disease in children with JIA, which suggests that the parent's rating of a child's disease activity should be considered for inclusion in the definition of clinical remission for JIA.

Abstract: OBJECTIVE: To investigate the proxy-reported health-related quality of life (HRQOL) and its determinants in patients with juvenile idiopathic arthritis (JIA). METHODS: In this multinational, multicenter, cross-sectional study, HRQOL of patients with JIA was assessed through the Child Health Questionnaire (CHQ) and was compared with that of healthy children of similar age from the same geographic area. Potential determinants of HRQOL included demographic data, physician's and parent's global assessments, measures of joint inflammation, Childhood Health Assessment Questionnaire (CHAQ), and erythrocyte sedimentation rate. RESULTS: A total of 6,639 participants (3,324 with JIA and 3,315 healthy) were enrolled from 32 countries. The mean +/- SD physical and psychosocial summary scores of the CHQ were significantly lower in patients with JIA than in healthy children (physical: 44.5 +/- 10.6 versus 54.6 +/- 4.0, P < 0.0001; psychosocial: 47.6 +/- 8.7 versus 51.9 +/- 7.5, P < 0.0001), with the physical well-being domain being most impaired. Patients with persistent oligoarthritis had better HRQOL compared with other subtypes, whereas HRQOL was similar across patients with systemic arthritis, polyarthritis, and extended oligoarthritis. A CHAQ score >1 and a pain intensity rating >3.4 cm on a 10-cm visual analog scale were the strongest determinants of poorer HRQOL in the physical and psychosocial domains, respectively. CONCLUSION: We found that patients with JIA have a significant impairment of their HRQOL compared with healthy peers, particularly in the physical domain. Physical well-being was mostly affected by the level of functional impairment, whereas the intensity of pain had the greatest influence on psychosocial health.

Abstract: We report herein the results of the cross-cultural adaptation and validation into the Italian language of the parent's version of two health related quality of life instruments. The Childhood Health Assessment Questionnaire (CHAQ) is a disease specific health instrument that measures functional ability in daily living activities in children with juvenile idiopathic arthritis (JIA). The Child Health Questionnaire (CHQ) is a generic health instrument designed to capture the physical and psychosocial well-being of children independently from the underlying disease. The Italian CHAQ was already published in the literature and was therefore revalidated while the Italian CHQ was fully cross culturally adapted with 3 forward and 3 backward translations, and than validated. A total of 1,192 subjects were enrolled: 404 patients with JIA (16% systemic onset, 31% polyarticular onset, 21% extended oligoarticular subtype, and 32% persistent oligoarticular subtype) and 788 healthy children. The CHAQ clinically discriminated between healthy subjects and JIA patients, with the systemic, polyarticular and extended oligoarticular subtypes having a higher degree of disability, pain, and a lower overall well-being when compared to their healthy peers. Also the CHQ clinically discriminated between healthy subjects and JIA patients, with the systemic onset, polyarticular onset and extended oligoarticular subtypes having a lower physical and psychosocial well-being when compared to their healthy peers. In conclusion the Italian version of the CHAQ-CHQ are reliable, and valid tools for the functional, physical and psychosocial assessment of children with JIA.

Abstract: The aim of this project was to cross-culturally adapt and validate the American English version of the Childhood Health Assessment Questionnaire (CHAQ) and of the Child Health Questionnaire (CHQ) in the 32 different member countries of the Paediatric Rheumatology International Trials Organisation (PRINTO). This effort forms part of an international study supported by the European Union to evaluate the health-related quality of life in children with juvenile idiopathic arthritis (JIA) as compared to their healthy peers. A total of 6,644 subjects were enrolled from 32 countries: Argentina, Austria, Belgium, Brazil, Bulgaria, Chile, Croatia, the Czech Republic, Denmark, Finland, France, Georgia, Germany, Greece, Hungary, Israel, Italy, Korea, Latvia, Mexico, the Netherlands, Norway, Poland, Portugal, Russia, Slovakia, Spain, Sweden, Switzerland, Turkey, the United Kingdom, and Yugoslavia. A total of 3,235 patients had JIA (20% systemic onset, 33% polyarticular onset, 17% extended oligoarticular subtype, and 30% persistent oligoarticular subtype) while 3,409 were healthy children. This introductory paper describes the methodology used by all the participants. The results and the translated version of both the CHAQ and the CHQ for each country are fully reported in the following papers. The results of the present study show that cross-cultural adaptation is a valid process to obtain reliable instruments for the different socio-economic and socio-demographic conditions of the countries participating in the project.

Abstract: Macrophage activation syndrome (MAS) is a potentially life threatening complication of chronic rheumatic diseases, particularly systemic juvenile idiopathic arthritis (JIA). A number of triggers have been related to the development of MAS, including viral infections, nonsteroidal antiinflammatory drug therapy, and gold salt injections. We describe a patient with systemic JIA who developed MAS shortly after receiving methotrexate, suggesting that this drug can be regarded as a potential trigger of MAS in children with JIA.
