OBJECTIVE: To investigate disease course, outcome, and predictors of outcome in an unselected population-based cohort of individuals diagnosed with juvenile chronic arthritis (JCA) followed for 17 years. METHODS: The cohort consisted of 132 incidence JCA cases identified 1984-1986 according to EULAR criteria. At 5-year followup, 129 individuals underwent joint assessment, laboratory measurements, radiographic examination, and medication and functional assessment. At 17-year followup, 86 were examined with joint assessment, laboratory measurements, medication assessment, Health Assessment Questionnaire (HAQ), Keitel functional test (KFT), and Medical Outcomes Study Short Form-36 (SF-36). RESULTS: At 17-year followup, 40% were in remission, 44% changed subgroups, median HAQ score was 0.0 (range 0.0-1.5), and median KFT was 100 (range 54-100). SF-36 scores were significantly lower compared to a reference group. Thirty-nine percent of those in remission at 5-year followup were not in remission at 17-year followup. In multivariate analyses of variables from the 17-year followup: remission was predicted by remission at 5-year followup (OR 4.8); HAQ > 0 by rheumatoid factor (RF)-positivity at 5-year followup (OR 3.6); KFT < 100 by nonremission (OR 11.3); and RF-positivity (OR 5.6) at 5-year followup; and the SF-36 physical component summary score above average of the reference group by remission at 5-year followup (OR 5.8). CONCLUSION: This longterm study of 86 individuals with JCA showed large variability of disease courses and of impaired health-related quality of life. Sixty percent were not in remission at 17-year followup. Longterm outcome was best predicted by and associated with characteristics at 5-year followup rather than those at onset.

The aim of the present study was to identify patterns of background factors related to the early RA patients' conceptions of the cause of the disease. Conceptions from a qualitative study formed the basis for the stratification of 785 patients from the Swedish EIRA study answering a question about their own thoughts about the cause to RA. Logistic regression analyses were used to explore the associations between patients' conceptions and relevant background factors: sex, age, civil status, educational level, anti-cyclic citrullinated peptide antibody (anti-CCP) and smoking habits. The results were presented as odds ratios (OR) with 95% confidence intervals (CI). A conception of family-related strain was strongly associated with being young (OR 0.50; 95% CI 0.33-0.78 for age 58-70 vs. 17-46), female (OR 0.38; 95% CI 0.25-0.60 for male vs. female) and having a high level of education (OR 2.15; 95% CI 1.54-3.01 for university degree vs. no degree). A conception of being exposed to climate changes was associated with being male (OR 1.99; 95% CI 1.24-3.22 for male vs. female), having a low level of education (OR 0.33; 95% CI 0.18-0.58 for university degree vs. no degree) and positive Anti-CCP (OR 1.72; 95% CI 1.03-2.87 for positive vs. negative Anti-CCP). Linking patients' conceptions of the cause of their RA to background factors potentially could create new opportunities for understanding the complexity of the aetiology in RA. Furthermore, this information is important and relevant in the care of patients with early RA.
