1 Review Consensus procedures and their role in pediatric rheumatology. 2008

Ruperto N, Meiorin S, Iusan SM, Ravelli A, Pistorio A, Martini A. · IRCCS G. Gaslini, Pediatria II-PRINTO, University of Genoa, Largo Gaslini, 5, 16147 Genova, Italy. · Curr Rheumatol Rep. · Pubmed #18460270 No free full text.

Abstract: The Delphi Technique and Nominal Group Technique are two well-recognized consensus-formation methodologies specifically designed to combine judgments from a group of experts. The Delphi Technique utilizes a series of well-defined questionnaire-based surveys, whereas Nominal Group Technique is a structured face-to-face meeting designed to facilitate consensus. Consensus-formation techniques require that each step build on the results of the previous steps. In this review, we describe these techniques, how they work, and their practical application in pediatric rheumatology, where they have been widely used to develop the outcome measures of several chronic rheumatic diseases, including juvenile idiopathic arthritis, rheumatoid arthritis, systemic lupus erythematosus, and idiopathic inflammatory myopathies, as well as the classification criteria for juvenile systemic sclerosis and juvenile vasculitides.

Ravelli A, Magni-Manzoni S, Pistorio A, Besana C, Foti T, Ruperto N, Viola S, Martini A. · Department of Pediatrics, Division of Pediatrics II, University of Genoa, Istituto G. Gaslini, Largo G. Gaslini 5, 16147 Genoa, Italy. · J Pediatr. · Pubmed #15870661 No free full text.

Abstract: OBJECTIVE: To develop diagnostic guidelines for macrophage activation syndrome (MAS) complicating systemic juvenile idiopathic arthritis (S-JIA). STUDY DESIGN: We followed the classification criteria approach that is based on the comparison of patients with the index disease with patients with a "confusable" disease. The former group included 74 patients with S-JIA-associated MAS reported in the literature or seen by the authors; the latter group included 37 patients with S-JIA who had 51 instances of "high disease activity" seen by the authors. The relative power of clinical, laboratory, and histopathologic variables in discriminating patients with MAS from patients with high disease activity was evaluated by calculating the sensitivity rate, specificity rate, area under the receiver operating characteristic curve, and diagnostic odds ratio (DOR). The combinations of variables that led to best separation between patients and control subjects were identified through "the number of criteria present" method. RESULTS: The strongest clinical discriminators were hemorrhages (DOR = 67) and central nervous system dysfunction (DOR = 63); the strongest laboratory discriminators were decreased platelet count (DOR = 1092), increased aspartate aminotransferase (DOR = 247), leukopenia (DOR = 70), and hypofibrinogenemia (DOR = 165). The best separation between patients and control subjects occurred when any 2 or more laboratory criteria (DOR = 1309) were simultaneously present; the second best performance was provided by the presence of any 2, 3, or more clinical and/or laboratory criteria (DOR = 765 and 743, respectively). CONCLUSION: We identified preliminary diagnostic guidelines for MAS complicating S-JIA. These guidelines deserve prospective validation.

Abstract: OBJECTIVE: To investigate the relationship between the magnitude of clinical response in the first 6 months of methotrexate (MTX) therapy and long-term outcome in children with juvenile idiopathic arthritis (JIA). METHODS: The clinical charts of 125 JIA patients who were started with MTX and then followed for at least 5 years were reviewed. Based on the level of American College of Rheumatology (ACR) Pediatric response at 6 months, patients were divided in four mutually exclusive groups: (1) non-responders, (2) responders at 30%, (3) responders at 50%, and (4) responders at 70%. The long-term outcome in each response group was evaluated by calculating the percentage change in active and restricted joint counts from baseline to 1, 2 and 5 years and the frequency of inactive disease at 5 years. RESULTS: At 6 months, 42 patients were classified as non-responders, 24 as 30% responders, 26 as 50% responders, and 33 as 70% responders. Patients who had achieved a 70% response showed a significantly greater percentage improvement in active joint count between baseline to 5 years compared with non-responders and 30% responders, and a significantly greater percentage improvement in restricted joint count between baseline to 5 years compared with 30% responders. The 70% responders also had a greater frequency of inactive disease at 5 years compared with 30% responders, CONCLUSIONS: Our results show that the achievement of an ACR Pediatric 70 response at 6 months after start of MTX therapy predicts a more favorable long-term outcome of patients with JIA.

4 Clinical Conference A randomized trial of parenteral methotrexate comparing an intermediate dose with a higher dose in children with juvenile idiopathic arthritis who failed to respond to standard doses of methotrexate. free! 2004

Abstract: OBJECTIVE: To compare the safety and efficacy of parenteral methotrexate (MTX) at an intermediate dosage (15 mg/m(2)/week) versus a higher dosage (30 mg/m(2)/week) in patients with polyarticular-course juvenile idiopathic arthritis (JIA) who failed to improve while receiving standard dosages of MTX (8-12.5 mg/m(2)/week). METHODS: In the screening phase, 595 patients who were newly started on a standard dose of MTX were followed up for 6 months. Subsequently, the nonresponders, defined according to the American College of Rheumatology (ACR) pediatric 30% improvement criteria (pediatric 30), were randomized to receive an intermediate dose or higher dose of parenteral MTX for an additional 6 months. Improvement in the screening and randomization phase was defined by the ACR pediatric 30 response, as well as by the 50% and 70% response levels (ACR pediatric 50 and ACR pediatric 70, respectively). RESULTS: In the screening phase, after receiving standard doses of MTX, 430 patients (72%) improved according to the ACR pediatric 30, while 360 (61%) met the ACR pediatric 50 and 225 (38%) met the ACR pediatric 70; among these patients, 69 (12%) also met the definition of complete disease control. Of the 133 nonresponders, 80 were randomized to receive an intermediate dose or higher dose of MTX. In the randomization phase, the ACR pediatric 30 response rate was 25 of 40 children (62.5%) in the intermediate-dose group versus 23 of 40 children (57.5%) in the higher-dose group. An ACR pediatric 50 response rate was attained by 23 patients (57.5%) receiving an intermediate dose versus 22 (55%) in the higher-dose group. An ACR pediatric 70 response rate was seen in 18 children (45%) receiving an intermediate dose versus 19 (47.5%) receiving a higher dose. Five children (12.5%) in the intermediate-dose group versus 4 (10%) receiving the higher dose of MTX also met the definition of complete disease control. None of the intergroup differences in response rate were significant. There were no significant differences in the frequency of adverse events or laboratory abnormalities between the 2 randomized groups. CONCLUSION: This study shows that the plateau of efficacy of MTX in JIA is reached with parenteral administration of 15 mg/m(2)/week and that a further increase in dosage is not associated with any additional therapeutic benefit. MTX should be administered for up to 9-12 months to appreciate its full therapeutic effect.

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.

6 Clinical Conference Responsiveness of outcome measures in juvenile chronic arthritis. Italian Pediatric Rheumatology Study Group. free! 1999

Matteo, Pavia, Italy. · Rheumatology (Oxford). · Pubmed #10342633 links to  free full text

Abstract: OBJECTIVE: To examine the responsiveness of the disease activity measures more commonly used in juvenile chronic arthritis (JCA) clinical trials. METHODS: Data were obtained from an open-label, non-controlled, multicentre trial designed to investigate the efficacy of methotrexate (MTX) in children with JCA. Outcome measures, including physician and parent global assessments, functional ability measures, articular variables, and laboratory indicators of systemic inflammation, were assessed at baseline and after 6 months of MTX treatment in 132 patients. Responsiveness of endpoint variables was evaluated by assessing the effect size (ES) and the standardized response median (SRM). RESULTS: Physician and parent global assessments were the more responsive instruments, showing ES and SRM above 1.0. Erythrocyte sedimentation rate, C-reactive protein, functional status measures and articular variables showed intermediate responsiveness. Morning stiffness, haemoglobin and platelet count were the least responsive instruments. CONCLUSION: The results of our analysis indicate that subjective estimations of the disease activity, either by the physician or parents, are the most responsive instruments in the assessment of the therapeutic response in children with JCA. The responsiveness of outcome measures in JCA should be further investigated in prospective controlled studies.

7 Article Development and validation of a composite disease activity score for juvenile idiopathic arthritis. 2009

Consolaro A, Ruperto N, Bazso A, Pistorio A, Magni-Manzoni S, Filocamo G, Malattia C, Viola S, Martini A, Ravelli A, Anonymous00061. · Istituto di Ricovero e Cura a Carattere Scientifico G.

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.

8 Article Achievement of a state of inactive disease at least once in the first 5 years predicts better outcome of patients with polyarticular juvenile idiopathic arthritis. 2009

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.

9 Article Development and testing of reduced joint counts in juvenile idiopathic arthritis. 2009

Bazso A, Consolaro A, Ruperto N, Pistorio A, Viola S, Magni-Manzoni S, Malattia C, Buoncompagni A, Loy A, Martini A, Ravelli A, Anonymous00093. · Istituto di Ricovero e Cura a Carattere Scientifico G.

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.

10 Article Magnetic resonance imaging, ultrasonography, and conventional radiography in the assessment of bone erosions in juvenile idiopathic arthritis. 2008

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 the disease outcomes of a cross-sectional sample of children with longstanding juvenile idiopathic arthritis (JIA) seen between September 2002 and December 2006, and to provide a benchmarking of outcomes obtained with current treatment. METHODS: All consecutive patients were included if they met the following criteria: diagnosis of JIA, disease duration > or = 5 years, and informed consent. Outcome assessments included disease activity, inactive disease, minimal disease activity, pain, physical function, health-related quality of life (HRQOL), auxometric measurements, and articular and extraarticular damage. RESULTS: A total of 310 patients were included. At study visit, patients had on average a low level of disease activity. However, only 21.8% met the criteria for inactive disease, and less than 50% met the definition of minimal disease activity. Additionally, 19.2% had moderate to severe Childhood Health Assessment Questionnaire disability and 3.6% were in Steinbrocker class III-IV. Approximately 10% had major impairment in HRQOL. A total of 34.2% had damage in > or = 1 joint or joint group and 26.1% showed extraarticular damage. Of the 125 patients who underwent a wrist radiograph, 35.2% had significant structural damage and 8.7% had growth retardation. CONCLUSION: Our patients had on average a low level of disease activity, little or no physical disability, and a satisfactory HRQOL. However, a sizable proportion of patients had persistently active disease, impaired function, and damage. These findings underscore the critical need for treatments and treatment strategies that have the ability to better control disease activity and to reduce the development of disease-related morbidities.

Abstract: OBJECTIVE: To develop and validate a definition of minimal disease activity (MDA) in patients with juvenile idiopathic arthritis (JIA). METHODS: The clinical charts of JIA patients followed over a 16-year period were reviewed to identify visits with high disease activity and MDA, defined on the basis of therapeutic decisions made by the attending physician. For each JIA activity measure recorded at the time of the visit, the cutoff value that best identified states of MDA was calculated by means of the area under the receiver operating characteristic curve analysis. A definition of MDA for oligoarthritis and polyarthritis was set up after testing the relative power of each variable in a multivariate analysis. Validation procedures included assessment of discriminant and construct validity. RESULTS: The definition that resulted from the analyses led to establish that a state of MDA could be defined as the presence of a physician global assessment < or =2.5 cm and a swollen joint count of 0 in patients with oligoarthritis; and as the presence of a physician global assessment < or =3.4 cm, a parent global assessment < or =2.1 cm, and a swollen joint count < or =1 in patients with polyarthritis. Validation procedures demonstrated that the MDA definition had good discriminant and construct validity in the context of both observational studies and controlled trials. CONCLUSION: We developed a preliminary definition of MDA in patients with JIA that represents a useful treatment target state and is proposed for inclusion as an outcome measure in future observational studies and clinical trials in patients with JIA.

13 Article A longitudinal analysis of physical functional disability over the course of juvenile idiopathic arthritis. 2008

Abstract: OBJECTIVE: To describe the longitudinal course of physical functioning in children with juvenile idiopathic arthritis (JIA) and identify predictors of long-term functional impairment. METHODS: Between January 1987 and December 2002, 227 patients had two or more functional ability questionnaires completed by a parent. The total number of questionnaires was 1356 and the follow-up between first and last questionnaire administration was 949.7 patient years. At each questionnaire administration, patients were assigned to one of three functional disability states (1 = no disability; 2 = mild to moderate disability; 3 = severe disability), based on their functional ability score. Predictor variables included sex, onset age, JIA category, age at visit, disease duration, presence of antinuclear antibodies, joint counts, acute phase reactants and initial disability state. RESULTS: Despite patient variability in the course of physical functioning, the following three longitudinal patterns were observed: (1) a stable state of disability throughout the entire study period, with continued absence of disability in 27.8% of patients and persistently moderate disability in 3.5% of patients; (2) a steady improvement (22.9% of patients) or deterioration (5.7% of patients) in disability over time; (3) a fluctuating course of disability, with deterioration and improvement (40.1% of patients). Younger age at disease onset and a greater restricted joint count were the strongest predictors of long-term functional impairment. CONCLUSION: A wide within-patient and between-patient variability in the longitudinal course of functional disability was found. Children with early disease onset and a greater number of restricted joints had the highest risk of developing long-term physical disability.

Abstract: OBJECTIVES: To examine the change in health-related quality of life (HRQOL) and its determinants in children with juvenile idiopathic arthritis (JIA) treated with methotrexate (MTX). METHODS: Patients were extracted from the PRINTO clinical trial which aimed to evaluate the efficacy and safety profile of MTX administered in standard, intermediate or higher doses (10, 15 and 30 mg/m(2)/week respectively). Children with polyarticular-course JIA, who were less than 18 years and had a complete HRQOL assessment were included. RESULTS: A total of 521 children were included. At baseline, patients with JIA showed poorer HRQOL (p<0.01) than healthy children. In 207/412 (50%) and 63 (15%) children, HRQOL values were 2 standard deviations below the mean of healthy controls in the physical and psychosocial summary scale, respectively. After 6 months of treatment with standard dose MTX, there was a statistically significant improvement in all HRQOL health concepts, particularly the physical ones. Similar improvements were observed in those who did not respond to a standard dose of MTX and were subsequently randomised to a higher dose. The presence of marked disability at baseline was associated with a fivefold increased risk of retaining poor physical health after 6 months of active treatment with standard dose MTX. Other less important determinants of retaining poor physical well-being were the baseline level of systemic inflammation, pain intensity and an antinuclear-antibody-negative status. CONCLUSIONS: MTX treatment produces a significant improvement across a wide range of HRQOL components, particularly in the physical domains, in patients with JIA.

15 Article Adapted versions of the Sharp/van der Heijde score are reliable and valid for assessment of radiographic progression in juvenile idiopathic arthritis. free! 2007

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.

16 Article Development and validation of a new short and simple measure of physical function for juvenile idiopathic arthritis. free! 2007

Abstract: OBJECTIVE: To develop and validate a new short and simple measure of physical function in children with juvenile idiopathic arthritis (JIA). METHODS: The Juvenile Arthritis Functionality Scale (JAFS) is a 15-item questionnaire that explores physical function in 3 body areas (lower limbs, hand/wrist, and upper segment). Validation of the Italian version of the instrument was accomplished by evaluating 211 consecutive JIA patients ages 2.2-18 years. The instrument's feasibility, face and content validity, construct and discriminative ability, internal consistency, interrater reliability, and responsiveness to clinical change were examined. JAFS psychometric properties were compared with those of the Childhood Health Assessment Questionnaire (C-HAQ). RESULTS: The JAFS was found to be feasible and to possess both face and content validity. The JAFS score correlated with most of the other JIA outcome measures in the range predicted, thereby demonstrating good construct validity, and discriminated well among different levels of disability. The internal consistency (Cronbach's alpha) was 0.82. The intraclass correlation coefficients between raters (mothers, fathers, and children) and between reported and observed level of function ranged from 0.65 to 0.84. The JAFS revealed fair responsiveness, with a standardized response mean ranging from 0.42 to 0.56. Comparison with the C-HAQ indicated that the JAFS may be superior in terms of construct validity and reliability, and at least as good in terms of discriminant validity and responsiveness. CONCLUSION: The JAFS exhibited good reliability, construct validity, and discriminative ability and fair responsiveness, and is therefore a valid instrument for the assessment of physical function in children with JIA.

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 identify epitopes on Escherichia coli heat-shock protein (HSP) dnaJ or on homologous human HSP dnaJ involved in the induction/modulation of autoimmune inflammation in patients with oligoarticular juvenile idiopathic arthritis (JIA). METHODS: We used a proliferation assay and cytokine production to evaluate the immune responses of synovial fluid mononuclear cells (SFMCs) to pan-HLA-DR binder peptides derived from either homologous or nonhomologous regions on bacterial and human HSP dnaJ. Cytofluorometric analysis was performed in order to phenotype and sort Treg cells. Sorted cells were then analyzed for the expression of the forkhead box P3 (FoxP3) transcription factor, and their regulatory capacity was tested in coculture assays. RESULTS: T cell responses to E coli HSP dnaJ-derived peptides were eminently proinflammatory. Conversely, peptides derived from human HSP dnaJ induced interleukin-10 (IL-10) production from SFMCs of patients with oligoarticular JIA. A positive correlation was found between disease with a better prognosis (persistent oligoarticular JIA) and recognition of 3 human HSP dnaJ-derived peptides. The recognition of the human peptide H134-148 also induced a significantly greater amount of IL-10 in patients with persistent oligoarticular JIA than in those with extended oligoarticular JIA (P = 0.0012). Incubation of SFMCs from patients with persistent oligoarticular JIA with this human epitope increased the percentage of Treg cells and FoxP3 expression. It also induced the recovery of suppressor activity by Treg cells. CONCLUSION: This is the first description of a self-regulating immune modulator circuit active during autoimmune inflammation through recognition of HSP epitopes with different functional properties. These epitopes induce T cells with regulatory function. Such induction correlates with disease severity and prognosis.

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: OBJECTIVE: To compare the correlation between juvenile idiopathic arthritis (JIA) measures of disease activity and damage in patients with early and late disease. METHODS: Three cohorts of patients with JIA disease duration < or =1 year (early disease, n = 70), 5-9.9 years (advanced disease, n = 114), and > or =10 years (longstanding disease, n = 39) were studied. Measures included physician's global assessment of overall disease activity (MD global), parent's global assessment of the child's well-being (parent global) and pain (parent pain), joint counts, Childhood Health Assessment Questionnaire (CHAQ), erythrocyte sedimentation rate, C-reactive protein level, and Poznanski score of radiographic damage. RESULTS: In all cohorts, the MD global assessment was generally well correlated with the other variables, except the Poznanski score. The parent global assessment was correlated strongly with the parent pain assessment and moderately with the CHAQ irrespective of disease duration. Correlations between the CHAQ and the joint counts were low in early disease, moderate in advanced disease, and high to moderate in longstanding disease. Correlation between the CHAQ and the Poznanski score was low in early and advanced disease and moderate in longstanding disease. The Poznanski score was highly correlated with the number of joints with restricted motion in longstanding disease. CONCLUSION: We found important differences in the level of correlation between JIA measures of activity and damage in patients with different lengths of disease duration. These findings have important implications for clinical trials because they indicate that the responsiveness of some variables and their correlation with other variables change as disease duration changes.

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: OBJECTIVES: To compare health-related quality of life (HRQL) and to identify clinical determinants for poor HRQL of patients with juvenile idiopathic arthritis (JIA) coming from three geographic areas. METHODS: The HRQL was assessed through the Child Health Questionnaire (CHQ). A total of 30 countries were included grouped in three geographic areas: 16 countries in Western Europe; 10 in Eastern Europe; and four in Latin America. Potential determinants of poor HRQL included demographic data, physician's and parent's global assessments, measures of joint inflammation, disability as measured by Childhood Health Assessment Questionnaire (CHAQ) and erythrocyte sedimentation rate. Poor HRQL was defined as a CHQ physical summary score (PhS) or psychosocial summary score (PsS) <2 S.D. from that of healthy children. RESULTS: A total of 3167 patients with JIA, younger than 18 yrs, were included in this study. The most affected health concepts (<2 S.D. from healthy children) that differentiate the three geographic areas include physical functioning, bodily pain/discomfort, global health, general health perception, change in health with respect to the previous year, self-esteem and family cohesion. Determinants for poor HRQL were similar across geographic areas with physical well-being mostly affected by the level of disability while the psychosocial well-being by the intensity of pain. CONCLUSION: We found that patients with JIA have a significant impairment of their HRQL compared with healthy peers, particularly in the physical domain. Disability and pain are the most important determinants of physical and psychosocial well-being irrespective of the geographic area of origin.

Abstract: OBJECTIVE: To investigate the discrepancy between physician's and parent's global assessments of disease status and the factors explaining discordance in patients with juvenile idiopathic arthritis (JIA). METHODS: The mothers of 197 patients with JIA rated the child's overall well-being on a 10 cm visual analogue scale (VAS) and the attending physician rated the child's overall disease activity on a 10 cm VAS. A discordance score was calculated by subtracting the physician's global assessment from that of the parent's, leading to the definition of three patient groups: (1) no discordance, when physician's and parent's assessments were within 1 cm of each other; (2) negative discordance, when parent's assessment was underrated relative to the physician; and (3) positive discordance, when parent's assessment was over-rated relative to the physician. Negative and positive discordance was defined as 'marked' when the difference between the two assessments was greater than 3 cm. RESULTS: No discordance was found in 40.6% of the patients. Negative discordance was found in 51.3% of the patients, with 34% showing marked discordance. Positive discordance was found in 8.1% of the patients, with 2% showing marked discordance. Significant differences between groups included a shorter disease duration among patients with a markedly positive discordance (P = 0.02) and a greater frequency of ongoing second-line drug therapy among patients with no discordance or with positive discordance (P = 0.008). Patients with no discordance or with marked positive discordance had a significantly lower joint counts (P = 0.02-0.004). CONCLUSION: Parents and physicians often perceive the health status of children with JIA differently, with parents providing most frequently lower rating.

Abstract: OBJECTIVE: To investigate the level of agreement between patients, mothers, fathers, and physicians in rating pain intensity in juvenile idiopathic arthritis (JIA), and to identify factors explaining discrepancies between raters. METHODS: Ninety-four children with JIA and their mothers and fathers were asked to rate independently the intensity of present pain and pain in the previous week on a visual analog scale. The physicians rated pain intensity after physical examination. Agreement between raters was determined using intraclass correlation coefficient and Bland and Altman method. Correlations of explanatory variables with discordance in rating pain intensity were determined by univariate and multivariate analyses. Explanatory variables included sex, age, JIA category, disease duration, results of study ratings, joint inflammation measures, and erythrocyte sedimentation rate. RESULTS: Agreement in rating present pain was moderate between children and mothers, but was poor between children and fathers and children and physicians. The agreement in rating pain in the previous week was moderate between children and mothers and children and fathers. Mother-father agreement was good. Parents and physicians agreed at a moderate level. In multiple regression analyses, only intensity of present pain was significantly associated with discordance within child-mother, child-father, and child-physician dyads. CONCLUSION: Children's ratings of pain were only in moderate agreement with those of their parents and were in poor agreement with those of the physicians, whereas the father and mothers agreed at a good level. The intensity of pain was the strongest determinant of discordance between children and other raters.

Abstract: OBJECTIVE: To develop a scoring system for juvenile idiopathic arthritis (JIA) in which joints are weighted to reflect their relative importance to children's function and to examine whether weighting increases the correlation of joint counts with subjective and laboratory outcome measures. METHODS: A weighted joint score was devised by a panel of experienced paediatric rheumatologists, who assigned a weight from 1 (not very important) to 10 (essential for key functional activities) to each joint based on its functional importance to children's physical and daily activities. The associations of simple and weighted counts of swollen, tender, limited and active joints with the physician's global assessment of overall disease activity, the parent's global assessment of the child's overall well-being and intensity of pain, the Childhood Health Assessment Questionnaire (C-HAQ), the Child Health Questionnaire (CHQ) and the erythrocyte sedimentation rate were compared using Spearman's correlation analysis in 60 unselected patients seen in the clinic and in 61 consecutive patients with disease duration > or = 5 yr. RESULTS: Weighted counts of swollen and active joints yielded greater correlation with the physician's global assessment than did simple counts. The correlation of weighted counts of swollen, painful and active joints with the parent's assessment of overall well-being and intensity of pain was superior to that provided by simple counts. Weighting increased most of the correlations between joint counts and the C-HAQ score and the physical component of the CHQ. CONCLUSION: Weighting improves the information provided by joint counts on the severity of arthritis and its impact on patients' well-being.
