    Abstract Biologics are a promising treatment option for juvenile idiopathic arthritis (JIA) but drug costs are very high compared to conventional treatment. From a socioeconomic view the additional costs of new interventions should be weighed against their incremental health benefits compared to standard care. Therefore we evaluated data on cost-effectiveness of biologics in JIA. We searched Medline, Embase, and The York Centre for Reviews and Dissemination database for relevant literature. Current data show that biologics are reducing direct and indirect healthcare costs if one excludes the costs of the drug itself. The costs of biologics are more than ten times as high as conventional drug treatment. As a result of limited data, no comparison on cost-effectiveness between biologics could be performed. Although data on long-term cost-effectiveness of biologics are lacking, the expectation is that they will be cost-effective in the long-term. The idea behind this is that biologic treatment should be administered to patients that without these drugs would incur high direct and indirect costs due to continuous severe disease resulting in irreversible disabilities. In our opinion the best cost benefit could be gained if these patients receive biologic treatment introduced early in the disease. This is in order to minimize irreversible damage to the joints and minimize need for long-term biologic therapy by early suppression of the disease. To support these hypotheses future research is needed on long-term cost-effectiveness of all biologics used in JIA.

    Abstract Objective: Remission is a key goal in managing rheumatoid arthritis (RA), with sustained remission as the preferred sequelae of short-term remission. However little is known about the predictors of sustained remission for patients reaching remission. Using two independent cohorts, we aimed to evaluate the prevalence and predictors for sustained remission.
    Methods: The study cohort consisted of subjects with RA from the Brigham and Women's Hospital Rheumatoid Arthritis Sequential Study (BRASS) and the Korean Observational Study Network for Arthritis (KORONA). We analyzed subjects who reached remission in 2009 with follow up data for two consecutive years. Remission was defined by the Disease Activity Score 28- (DAS28-CRP) of less than 2.6. Sustained remission was defined as three consecutive annual visits in remission. Predictors for sustained remission were identified by multivariate logistic regression analysis.
    Results: A total of 465 subjects were in remission in 2009. Sustained remission was achieved by 53 of 92 (57.5%) in BRASS and by 198 of 373 (53.1%) in KORONA. In multivariate analyses, baseline predictors of sustained remission were: disease duration less than 5 years [odds ratio (OR) 1.96, 95% confidence interval (95% CI) 1.08-3.58], Modified Health Assessment Questionnaire (MHAQ) score of 0 (OR 1.80, 95% CI 1.18-2.74), and non-use of oral glucocorticoid (OR 1.58, 95% CI 1.01-2.47).
    Conclusion: More than half of RA subjects in remission in 2009 remained in remission through 2011. Short disease duration, no disability, and non-use of oral glucocorticoid at baseline were associated with sustained remission.

    Title translation Venous thrombosis as a first sign of SLE.
    Abstract Background: Venous thrombosis in children is rare. In adolescents it may be the first manifestation of a chronic disease such as systemic lupus erythematosus (SLE).
    Case description: An obese 12-year-old girl visited the Obesity Clinic and mentioned pain in her right calf. Some time before her arrival she spent time in bed with a respiratory infection. Deep vein thrombosis was diagnosed by ultrasonography. Radiography showed an infiltrate, laboratory tests showed elevated inflammatory parameters, and thrombophilia testing showed a Factor V Leiden mutation as well as the presence of lupus anticoagulants. During her stay she developed haematological, immunological and clinical signs of SLE.
    Conclusion: The cause of venous thrombosis in children is usually multifactorial. Despite the presence of obvious risk factors, it is important to follow adolescents with thrombosis and to be alert for any signs of an underlying systemic disease.

    Abstract Objective: Around one-third of patients with juvenile idiopathic arthritis (JIA) fail to respond to first-line methotrexate (MTX) or anti-tumor necrosis factor (TNF) therapy, with even fewer achieving ≥ American College of Rheumatology Pediatric 70% criteria for response (ACRpedi70), though individual responses cannot yet be accurately predicted. Because change in serum S100-protein myeloid-related protein complex 8/14 (MRP8/14) is associated with therapeutic response, we tested granulocyte-specific S100-protein S100A12 as a potential biomarker for treatment response.
    Methods: S100A12 serum concentration was determined by ELISA in patients treated with MTX (n = 75) and anti-TNF (n = 88) at baseline and followup. Treatment response (≥ ACRpedi50 score), achievement of inactive disease, and improvement in Juvenile Arthritis Disease Activity Score (JADAS)-10 score were recorded.
    Results: Baseline S100A12 concentration was measured in patients treated with anti-TNF [etanercept n = 81, adalimumab n = 7; median 200, interquartile range (IQR) 133-440 ng/ml] and MTX (median 220, IQR 100-440 ng/ml). Of the patients in the anti-TNF therapy group, 74 (84%) were also receiving MTX. Responders to MTX (n = 57/75) and anti-TNF (n = 66/88) therapy had higher baseline S100A12 concentration compared to nonresponders: median 240 (IQR 125-615) ng/ml versus 150 (IQR 87-233) ng/ml, p = 0.021 for MTX, and median 308 (IQR 150-624) ng/ml versus 151 (IQR 83-201) ng/ml, p = 0.002, for anti-TNF therapy. Followup S100A12 could be measured in 44/75 MTX-treated patients (34/44 responders) and 39/88 anti-TNF-treated patients (26/39 responders). Responders had significantly reduced S100A12 concentration (MTX: p = 0.031, anti-TNF: p < 0.001) at followup versus baseline. Baseline serum S100A12 in both univariate and multivariate regression models for anti-TNF therapy and univariate analysis alone for MTX therapy was significantly associated with change in JADAS-10.
    Conclusion: Responders to MTX or anti-TNF treatment can be identified by higher pretreatment S100A12 serum concentration levels.
