Comparison of the Disease Activity Score-28 and Juvenile Arthritis Disease Activity Score in the juvenile idiopathic arthritis
Introduction: the assessment of the activity of rheumatoid arthritis and juvenile idiopathic arthritis is made by means of different tools, respectively DAS-28 and JADAS.Objective: To compare DAS-28 and JADAS with scores of 71, 27 and 10 joint counts in juvenile idiopathic arthritis.Method: A secondary analysis of a phase III placebo-controlled trial, testing safety and efficacy of abatacept was conducted in 8 patients with 178 assessment visits. Joint count scores for active and limited joints, physician's and parents'global assessment by 0-10 cm Visual Analog Scale, and erythrocyte sedimentation rate normalized to 0-10 scale, in all visits. The comparison among the activity indices in different observations was made through Anova or adjusted gamma model. The paired observations between DAS-28 and JADAS 71, 27 and 10, respectively, were analyzed by linear regression.Results: There were significant differences among individual measures, except for ESR, in the first four months of biological treatment, when five of the eight patients reached ACR-Pedi 30, with improvement. The indices of DAS-28, JADAS 71, 27 and 10 also showed significant difference during follow-up. Linear regression adjusted model between DAS-28 and JADAS resulted in mathematical formulas for conversion: [DAS-28 = 0.0709 (JADAS 71) + 1.267] (R-2 = 0.49); [DAS-28 = 0.084 (JADAS 27) + 1.7404] (R-2 = 0.47) and [DAS-28 = 0.1129 (JADAS-10) + 1.5748] (R-2 = 0.50).Conclusion: The conversion of scores of DAS-28 and JADAS 71, 27 and 10 for this mathematical model would allow equivalent application of both in adolescents with arthritis.

Objetivo: Comparar o DAS-28 e o JADAS com a pontuação de 71, 27 e 10 articulações, na artrite idiopática juvenil. Método: Foram avaliadas 178 visitas em oito pacientes com artrite idiopática juvenil, participantes de um ensaio clínico controlado de fase III, testando eficácia e segurança do abatacepte. Pontuaram-se as articulações ativas e limitadas, a avaliação global pelo médico e pelos pais em escala analógica visual de 0-10 cm e a velocidade de hemossedimentação convertida em escala de 0-10, em todas as visitas. A comparação entre os índices de atividade entre diferentes observações foi por Anova ou modelo ajustado Gama. As observações pareadas entre o DAS-28 e o JADAS 71, 27 e 10, respectivamente, foram analisadas por meio de regressão linear. Resultados: Houve diferença significativa entre as medidas individuais, exceto a VHS, nos primeiros quatro meses de tratamento com biológico, quando cinco entre os oito pacientes atingiram a resposta ACR-Pedi 30, com melhora. Os índices DAS-28, JADAS 71, 27 e 10 também apresentaram diferença relevante durante o período de observação. O ajustamento por meio de regressão linear entre o DAS-28 e o JADAS resultou em fórmulas matemáticas para conversão: [DAS-28 = 0,0709 (JADAS 71) + 1,267] (R2 = 0,49); [DAS-28 = 0,084 (JADAS 27) + 1,7404] (R2 = 0,47) e [DAS-28 = 0,1129 (JADAS-10) + 1,5748] (R2 = 0,50). Conclusão: A conversão da pontuação do DAS-28 e do JADAS 71, 27 e 10 por esse modelo matemático permitiria a aplicação equivalente de ambos em adolescentes com artrite

2016 American College of Rheumatology/European League Against Rheumatism criteria for minimal, moderate, and major clinical response in juvenile dermatomyositis : An International Myositis Assessment and Clinical Studies Group/Paediatric Rheumatology International Trials Organisation collaborative initiative
To develop response criteria for juvenile dermatomyositis (DM). We analysed the performance of 312 definitions that used core set measures from either the International Myositis Assessment and Clinical Studies Group (IMACS) or the Paediatric Rheumatology International Trials Organisation (PRINTO) and were derived from natural history data and a conjoint analysis survey. They were further validated using data from the PRINTO trial of prednisone alone compared to prednisone with methotrexate or cyclosporine and the Rituximab in Myositis (RIM) trial. At a consensus conference, experts considered 14 top candidate criteria based on their performance characteristics and clinical face validity, using nominal group technique. Consensus was reached for a conjoint analysis-based continuous model with a total improvement score of 0-100, using absolute per cent change in core set measures of minimal (≥30), moderate (≥45), and major (≥70) improvement. The same criteria were chosen for adult DM/polymyositis, with differing thresholds for improvement. The sensitivity and specificity were 89% and 91-98% for minimal improvement, 92-94% and 94-99% for moderate improvement, and 91-98% and 85-86% for major improvement, respectively, in juvenile DM patient cohorts using the IMACS and PRINTO core set measures. These criteria were validated in the PRINTO trial for differentiating between treatment arms for minimal and moderate improvement ( p=0.009-0.057) and in the RIM trial for significantly differentiating the physician's rating for improvement (p<0.006). The response criteria for juvenile DM consisted of a conjoint analysis-based model using a continuous improvement score based on absolute per cent change in core set measures, with thresholds for minimal, moderate, and major improvement
Phenotypic variability and disparities in treatment and outcomes of childhood arthritis throughout the world: an observational cohort study.
BACKGROUND:To our knowledge, the characteristics and burden of childhood arthritis have never been studied on a worldwide basis. We aimed to investigate, with a cross-sectional study, the prevalence of disease categories, treatment methods, and disease status in patients from across different geographical areas and from countries with diverse wealth status.
METHODS: In this multinational, cross-sectional, observational cohort study, we asked international paediatric rheumatologists from specialised centres to enrol children with a diagnosis of juvenile idiopathic arthritis, according to International League of Associations for Rheumatology criteria, who were seen consecutively for a period of 6 months. Each patient underwent retrospective and cross-sectional assessments, including measures of disease activity and damage and questionnaires on the wellbeing and quality of life of the children. We qualitatively compared the collected data across eight geographical areas, and we explored an association between disease activity and damage and a country\u27s gross domestic product (GDP) with a multiple logistic regression analysis.
FINDINGS: Between April 4, 2011, and Nov 21, 2016, 9081 patients were enrolled at 130 centres in 49 countries, grouped into eight geographical areas. Systemic arthritis (125 [33·0%] of 379 patients) and enthesitis-related arthritis (113 [29·8%] of 379) were more common in southeast Asia, whereas oligoarthritis was more prevalent in southern Europe (1360 [56·7%] of 2400) and rheumatoid factor-negative polyarthritis was more frequent in North America (165 [31·5%] of 523) than in the other areas. Prevalence of uveitis was highest in northern Europe (161 [19·1%] of 845 patients) and southern Europe (450 [18·8%] of 2400) and lowest in Latin America (54 [6·4%] of 849), Africa and Middle East (71 [5·9%] of 1209), and southeast Asia (19 [5·0%] of 379). Median age at disease onset was lower in southern Europe (3·5 years, IQR 1·9-7·3) than in other regions. Biological, disease-modifying antirheumatic drugs were prescribed more frequently in northern Europe and North America than in other geographical settings. Patients living in countries with lower GDP had greater disease activity and damage than those living in wealthier countries. Damage was associated with referral delay.
INTERPRETATION: Our study documents a variability in prevalence of disease phenotypes and disparities in therapeutic choices and outcomes across geographical areas and wealth status of countries. The greater disease burden in lower-resource settings highlights the need for public health efforts aimed at improving equity in access to effective treatments and care for juvenile idiopathic arthritis
