Objective: To evaluate changes in health-related quality of life (HRQoL) in patients with refractory juvenile idiopathic arthritis (JIA) who are being treated with etanercept. Methods: 53 patients with JIA from seven Dutch centres were included. HRQoL was measured by the Childhood Health Assessment Questionnaire (CHAQ), Child Health Questionnaire (CHQ) and Health Utilities Index mark 3 (HUI3) at the start and after 3, 15 and 27 months of treatment. At the same time points the following JIA disease activity variables were collected; physician's global assessment through the visual analogue scale (VAS), number of active and limited joints and erythrocyte sedimentation rate. A statistical method linear mixed models was used to assess outcomes over time. Results: During etanercept treatment both disease-specific and generic HRQoL outcomes improved dramatically. Significant improvements were shown after 3 months and these improvements continued at least up to 27 months of treatment. The disease-specific CHAQ, including VAS pain and wellbeing, showed a significant improvement in all domains. The generic health-profile measure CHQ improved for all the health concepts except for "family cohesion", which was normal. The generic preference-based HUI3 showed impairment and, subsequently, significant improvement in the more specific domains ("pain", "ambulatory", "dexterity"). In accordance disease activity variables also improved significantly over time. Conclusion: This study shows that the HRQoL of patients with refractory JIA can be substantially improved by the use of etanercept for all aspects impaired by JIA. Information on HRQoL is crucial to understand the complete impact of etanercept treatment on patients with JIA and their families. Source

Objective. To evaluate the effectiveness and safety of biological agents in children with enthe - sitis-related arthritis (ERA). Methods. All patients with ERA in whom a biological agent was initiated between 1999 and 2010 were selected from the Dutch Arthritis and Biologicals in Children (ABC) register. In this ongoing multicenter observational register, data on the course of the disease and medication use are retrieved prospectively at the start of the biological agent, after 3 months, and yearly thereafter. Inactive disease was assessed in accordance with the Wallace criteria. Results. Twenty-two patients with ERA started taking 1 or more biological agents: 20 took etanercept, 2 took adalimumab (1 switched from etanercept to adalimumab), and 2 took infliximab (1 switched from etanercept to infliximab). Characteristics: 77% were male, 77% had enthesitis, 68% were HLA-B27-positive. The median age of onset was 10.4 (IQR 9.4-12.0) years; median follow-up from the start of the biological agent was 1.2 (IQR 0.5-2.4) years. Intention-to-treat analysis shows that inactive disease was achieved in 7 of 22 patients (32%) after 3 months, 5 of 13 patients (38%) after 15 months, and 5 of 8 patients (63%) after 27 months of treatment. Two patients discontinued etanercept because of ineffectiveness, and switched to adalimumab (inactive disease achieved) or infliximab (decline in joints with arthritis after 3 months of treatment). One patient discontinued etanercept because of remission, but had flare and restarted treatment, with good clinical response. No serious adverse events occurred. Conclusion. Tumor necrosis factor (TNF)-blocking agents seem effective and safe for patients with ERA that was previously unresponsive to 1 or more DMARD. However, a sustained disease-free state could not be achieved, and none discontinued TNF-blocking agents successfully. The Journal of Rheumatology Copyright © 2011. All rights reserved. Source
