  Objectives: Ultrasonography is an effective, low-cost, low-threshold and convenient diagnostic tool in childhood arthritis, but its value in temporomandibular joint (TMJ) involvement is not clear. The purpose of our study was to explore the reliability of ultrasonography to assess TMJ inflammation using contrast-enhanced MRI as reference standard, in order to deduce cut-off values for TMJ capsular width to detect enhanced synovial thickening (synovitis). Methods: 124 ultrasonography and MRI examinations in 55 patients [mean age 12.4 ± 3.5 years (±standard deviation)], the majority obtained within 1 day, were scored for subcondylar and condylar capsular width (ultrasonography images) and amount of synovitis (MR images). The correlations of these findings were calculated. A receiver operating characteristic (ROC) curve analysis, with MRI findings as reference standard, was obtained. Results: The correlation between ultrasonography-assessed capsular width and MRI-assessed amount of synovitis was moderate both at the subcondylar and condylar level [Spearman's rho (ρ): 0.483; p < 0.001 and 0.347; p < 0.001 respectively]. The ROC curve indicated the best discriminatory ability at the subcondylar level with an area under the curve of 0.77 (95% confidence interval 0.69–0.85) and a cut-off value of 1.2 mm (sensitivity 72%, specificity 70%) for the capsular width. Conclusions: A moderate correlation between ultrasonography-assessed capsular width and MRI-assessed synovitis was found in childhood arthritis with the best discriminatory ability at the subcondylar level. This indicates that ultrasonography may be a valuable diagnostic tool in the initial assessment of TMJ inflammation.

  Objective. Juvenile idiopathic arthritis (JIA) is the most common inflammatory rheumatic disease in childhood. It is regarded as a systemic inflammatory disease with possible increased risk of cardiovascular disease (CVD). The aim of this study was to assess carotid intima-media thickness (IMT) and carotid stenosis as surrogate measures for CVD in adults with longterm active JIA and healthy age- and sex-matched controls. Methods. Seventy-five patients with JIA (age 28–45 yrs) with persistently active disease at least 15 years after disease onset were reexamined after a median of 29 years and compared with 75 matched controls. Patients and controls were examined by color duplex ultrasound of the carotid arteries to compare carotid IMT and carotid stenosis in the 2 groups. Results. Patients with JIA did not have increased carotid IMT values compared with the controls (mean ± SD: 0.56 mm ± 0.09 vs 0.58 mm ± 0.07, p = 0.289). Patients with a higher disease activity indicated by the Juvenile Arthritis Disease Activity Score value above the median value had increased carotid IMT compared with the patients with a lower value, but not statistically different compared with controls. No carotid stenoses were detected in patients or controls. Conclusion. We found similar carotid IMT values in adult patients with JIA and controls.

  Objectives. Low heart rate variability (HRV) is a well-established predictor of cardiac death. The aim of this study was to investigate arrhythmias and HRV in patients with JDM, and associations between HRV and inflammatory markers, echocardiographic measurements and disease parameters. Methods. Fifty-five patients with JDM were examined 2–34 years (median 13.5 years) after disease onset, and compared with 55 age and sex matched controls. Holter ECG monitoring and echocardiography were analysed blinded to patient information. Arrhythmia and HRV (six parameters) were analysed by standard software, finally adjudicated by an experienced cardiologist. Markers of inflammation (ESR, high sensitivity (hs)CRP and cytokines) were analysed. Disease activity and organ damage were assessed by clinical examination at follow-up and retrospectively by chart review. Results. In two out of six HRV parameters, JDM patients had lower values than controls. No difference in arrhythmias was found between the groups. In patients, but not in controls, there were significant negative correlations between five out of six HRV parameters, and ESR and hsCRP (Spearman correlation coefficient, −0.306 to −0.470; P, 0.023 to <0.001). Also, in patients, negative correlations were found between three out of six HRV parameters and systolic and diastolic function. Active disease and low HRV were associated. Patients with hsCRP in the highest quartile (Q4) had lower HRV in all parameters compared with those in pooled Q1–3 (P < 0.001). Conclusion. JDM patients had reduced HRV, which was associated with elevated inflammatory markers, active disease and reduced myocardial function. This suggests reduced vagal control of the heart; further studies are needed to determine whether this is also associated with cardiac morbidity or mortality.

  Background MRI manifestation of temporomandibular joint arthritis is frequently reported in children with juve- nile idiopathic arthritis. However, little attention has been paid to temporomandibular joint disk abnormalities. Objective To assess combinations of MRI findings in the symptomatic temporomandibular joint in children with ju- venile idiopathic arthritis with focus on disk abnormalities. Materials and methods This was a retrospective study of 46 patients with juvenile idiopathic arthritis, mean age 12 years (range: 5-17 years). Mean disease duration was 70 months (standard deviation: 61 months). MR images of 92 tempo- romandibular joints were scored for thickness of abnormal- ly enhancing synovium (synov itis), joint effusion, bone marrow oedema, abnormal bone shape, bone erosion and disk abnormalities. Results The 92 temporomandibular joints were categorized as A: No synovitis and normal bone shape (30/92; 33%), B: Synovitis and normal bone shape (14/92: 15%), C: Synovi- tis and abnormal bone shape (38/92; 41%) and D: No syno- vitis but abnormal bone shape (10/92; 11%). Thirty-six of the 46 patients (78%) had synovitis and 33/46 (72%) had abnormal bone shape, most frequently in combination (30/ 46; 65%). Disk abnormalities (flat disk, fragmented disk, adherent disk and displaced disk) were found in 29/46 pa- tients (63%). Disk abnormalities were found in all catego- ries of juvenile idiopathic arthritis involved temporoman- dibular joints (B: 8/14 [57%]; C: 25/38 [66%] and D: 7/10 [70%]). Disk displacement was found in half of the joints (7/14) in category B. Synovitis was most pronounced in this category. Conclusion Disk abnormalities were frequent. Disk displace- ment also occurred in joints with early temporomandibular joint arthritis, i.e., with normal bone shape. Other disk abnor- malities were found in joints with bone abnormalities. Atten- tion should be paid to disk abnormalities both in early and long-standing temporomandibular joint arthritis in children with juvenile idiopathic arthritis

  Expression of the major autoimmune risk loci DRB1 and DQB1 is regulated by the class II MHC (major histocompatibility complex) transactivator (CIITA), making the CIITA gene a strong autoimmune risk locus candidate. A CIITA promoter single-nucleotide polymorphism (SNP), rs3087456 (-168 A/G), has indeed been associated with several autoimmune diseases, including rheumatoid arthritis (RA). Recently, an intronic SNP rs8048002 has been suggested as a better susceptibility marker in Addison's disease. Therefore, we tested both SNPs in a panel of autoimmune diseases, consisting of Norwegian patients with RA (n=819), juvenile idiopathic arthritis (JIA; n=524), or type 1 diabetes (T1D; n=1211), and 2149 controls. We also included an independent Swedish RA cohort (n=2503) and controls (n=1416). Both rs3087456 and rs8048002 were significantly associated with RA (combined Norwegian and Swedish patients P(corrected)=0.012 and P(corrected)=0.0016, respectively), but not with JIA or T1D. Meta-analysis of 16 RA cohorts confirmed rs3087456 with only marginal significance (P=0.016). However, results were stronger in the Scandinavian subgroup (4 cohorts, P=3.8 × 10(-4)), indicating a population-dependent effect. A similar pattern was observed in a meta-analysis of rs8048002. Our results support involvement of CIITA in RA, but imply that this is population dependent and that the aetiological variant is yet to be discovered.

  Objective: To explore self-rated physical and psychosocial health in a cohort of young adults with juvenile idiopathic arthritis (JIA) 18.3 years after symptom onset, make comparisons with population-based data, and illuminate possible predictors of self-rated health. Methods: Of a baseline cohort of 84 patients with JIA, 55 (65.5%) answered the self-administered questionnaires of the Health Assessment Questionnaire (HAQ), the Visual Analogue Scale (VAS) of pain, fatigue, and illness, the Medical Outcomes Study 36-item Short Form Health Survey (SF-36), and the General Health Questionnaire (GHQ-30). Telephone interviews were conducted with 51/55 patients. Population-based norm-data of SF-36 were used for comparison. Results: Significantly impaired physical health but no difference in psychosocial health was found as compared to the general Norwegian population. The level of education was significantly higher whereas no difference was found in employment status as compared to norm-data. Pain was a significant correlate of the education level. Predictors of physical impairment were physical disability and pain, whereas psychiatric distress and female sex were predictors of mental ill-health. Conclusion: Physical disability does not seem to have a negative influence on the patients? functioning psychosocially.

  Objective: The aim was to describe physical and psychosocial health status in a second follow-up of a cohort of patients with chronic childhood arthritis, to compare results from the present study with the first follow-up, and to explore the course of physical and psychosocial functioning from baseline. Methods: At a median of 18.3 years after symptom onset 55 patients answered the self-administered questionnaires Health Assessment Questionnaire Disability Index (HAQ-DI), Visual Analogue Scales (VAS) of pain, fatigue and illness, and General Health Questionnaire (GHQ) 30-item version. Results from the current study were compared to first follow-up median 8.7 years after symptom onset, and the course of physical and psychosocial function from baseline was discussed. Results: At second follow-up, 38% reported HAQ-DI above 0 indicating physical disability, 22% had a GHQ-30 score in the clinical range indicating psychiatric distress, and fatigue seemed to be an overarching aspect of the health status. Pain was an important correlate of physical disability at first and second follow-up. At second follow-up psychiatric distress was a significant correlate of pain and fatigue, indicating a relation to disease severity. The association between psychosocial functioning and chronic family difficulties observed at first follow-up is not evident at second follow-up. Conclusions: The favourable physical and psychosocial outcome reported at first follow-up seems to persist. However, arthritis-related ill-health is still evident in a considerable proportion of the patients, indicating a constant impact of the disease on every-day life of the individual.

  Abstract Objectives To investigate the long term effect (week 16) of a 4-week rehabilitation programme for patients with rheumatoid arthritis (RA), and to compare the effect of this intervention given in a Mediterranean or a Norwegian climate. Methods A randomised, controlled, parallel group design, where 124 RA patients applying for rehabilitation were randomized to a rehabilitation programme either in Norway or in a Mediterranean climate. The participants were examined clinically immediately before (week 0) and after (week 4) the rehabilitation period as well as in week 16 and answered a mailed questionnaire in week 28. The 28-Joint Disease Activity Score (DAS28), American College of Rheumatology (ACR) response and physical tests were used to measure clinical response. Results The baseline DAS28 value 4.45(1.16) was reduced by -0.95 (1.05) in the Mediterranean climate and the baseline DAS28 value 4.18 (1.17) was reduced by -0.37(0.92) in the Norwegian climate at week 16 (p=0.003). An ACR20 improvement was achieved in 25% of the patients treated in the Mediterranean climate and 15% of those treated in the Norwegian climate. Sustained improvement in all ACR core components at week 16 and in patient’s assessment of health status at week 28 was found in the patients treated in the Mediterranean climate only. Tests of physical function, the 6-Minute Walk Test (6MWT) and the Timed Up and Go (TUG) showed comparable improvements in patients treated in both climates. Conclusions RA patients have positive immediate effects on disease activity, physical function, and symptoms during a 4-week rehabilitation programme. The effects on disease activity and symptoms are larger and better maintained at least 3 months after rehabilitation in a warm than in a cold climate.
