Resumo
Objetivo: Caracterizar a atividade inflamatória articular e sistêmica na Artrite Idiopática Juvenil (AIJ), determinando o estado de remissão com e sem uso de medicação. Métodos: Cento e sessenta e cinco casos de AIJ classificados segundo os critérios de 2004 da Liga Internacional de Associações de Reumatologia (ILAR), acompanhados no serviço de Reumatologia Pediátrica FMB-UNESP, entre 1986 e 2005 com uma média de seguimento de 3,6 anos, foram revisados para caracterização de episódios de inatividade, remissão clínica com e sem uso de medicação, selecionando-se aqueles com acompanhamento mínimo de 1 ano. Foram analisados os descritores dos subtipos de AIJ. A freqüência de inatividade e remissão, para a comparação entre os subtipos de artrite e dos grupos que atingiram ou não remissão foram analisados por meio de estatística descritiva, análise de sobrevida por curvas de Kaplan-Meier, comparação das curvas por teste Log Rank e a análise de regressão logística para identificação de fatores preditivos para a remissão ou persistência de atividade. Resultados: Cento e oito casos preencheram os critérios de inclusão, sendo 58,3% oligoarticular persistente, 8,3% oligoarticular estendido, 1,8% poliarticular fator reumatóide positivo (FR+), 10,2% poliarticular reumatóide negativo (FR-), 12% sistêmico, 0,9% artrite psoriásica, 4,6% artrite relacionada a entesite, e 3,7% artrite indiferenciada. Dez por cento apresentavam anticorpos antinucleares (AAN) e 7,4% apresentavam uveíte. Cinqüenta e sete pacientes apresentaram um total de 71 episódios de inatividade durante o acompanhamento, com 2,9 anos em média para cada episódio. Trinta e seis episódios (50,7%) de inatividade resultaram em remissão clínica sem medicação (RC), sendo 35% para oligoarticular persistente. A probabilidade de remissão clínica em uso de medicação em 3 anos foi...
Objective: To estimate the clinical remission on medication and off medication rates in Juvenile Idiopathic Arthritis (JIA) by determining the articular and systemic inflammatory activity. Methods: One hundred and sixty five cases of JIA, classified according to the 2004 International League of Associations for Rheumatology criteria, attending the Rheumatology Unit FMB-UNESP from 1986 to 2005, with median follow up 3,6 years, were reviewed for recording inactive disease, clinical remission on medication and clinical remission off medication. Cases with at least one year of regular follow up were selected. All JIA subtypes descriptors were evaluated. Inactivity and remission rates were compared by survival analyses with Kaplan-Meier curves and Log Rank test. Remission predictors and risk factors for persistent activity were identified by logistic regression analysis. Results: One hundred and eight cases met the inclusion criteria, being 58,3% persistent oligoarticular, 8,3% extended oligoarticular, 1,8% polyarticular rheumatoid factor positive (RF+), 10,2% polyarticular rheumatoid factor negative (RF-), 12% systemic, 0,9% psoriatic arthritis, 4,6% enthesitis related arthritis and 3,7% undifferentiated arthritis. Ten percent had antinuclear antibodies (ANA) and 7,4% had uveitis. Fifty-seven patients experienced a total of 71 episodes of inactive disease (ID), during the entire follow-up, with a median episode duration of 2,9 years. The patients attained inactive disease from one to four times. Thirty-six episodes (50,7%) of ID resulted in clinical remission (CR) off medication, being 35% for persistent oligoarticular. The probability of clinical remission on medication (CRM) within 3 years, was 63%, 83% and 60%, respectively for persistent oligoarticular, polyarticular and systemic arthritis cases. The probability of clinical remission... (Complete abstract click eletronic address below)
