ABSTRACT

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.

ABSTRACT

OBJECTIVE: To assess whether the removal of aids/devices and/or help from another person in the Childhood Health Assessment Questionnaire (C-HAQ) leads to a significant change in the disability index (DI) score and responsiveness in juvenile idiopathic arthritis (JIA). METHODS: Changes in the C-HAQ DI score in a cross-sectional sample of 2663 children with JIA and in 530 active patients with JIA in a trial of methotrexate (MTX) were compared. RESULTS: Patients in the MTX trial had higher disease activity and disability than the cross-sectional sample. The frequency of aids/devices (range 1.2-10.2%) was similar between the two samples, while help (range 5.3-38.1%) was more frequently used in the MTX group. Correlation between disease severity variables and the two different C-HAQ DI scoring methods did not change substantially. There was a decrease in the C-HAQ DI score for both the cross-sectional (mean score from 0.64 with the original method to 0.54 without aids/devices and help, p<0.0001) and the MTX sample (mean score from 1.23 to 1.07, p<0.0001). A linear regression analysis of the original C-HAQ DI score versus the score without aids/devices and help demonstrated the substantial overlap of the different scoring methods. Responsiveness in the responders to MTX treatment did not change with the different C-HAQ DI scoring methods (range 0.86-0.82). CONCLUSION: The removal of aids/devices and help from the C-HAQ does not alter the interpretation of disability at a group level. The simplified C-HAQ is a more feasible and valid alternative for the evaluation of disability in patients with JIA.

ABSTRACT

OBJECTIVE: Temporomandibular joint (TMJ) involvement is a frequent feature in cross-sectional prevalence studies among juvenile idiopathic arthritis (JIA) patients. The cross-sectional design makes it almost impossible to study the incidence. Follow-up data on TMJ involvement are sparse. In this study patients were reviewed with an interval of a minimum of 1 year and a maximum of 2 years to study the yearly incidence of TMJ involvement and to obtain follow-up data on TMJ involvement and orthopantomogram (OPT) alterations. METHODS: Children with JIA from a previous study on TMJ involvement were included. OPTs were scored according to Rohlin's grading system (grade 0-5). A paediatric rheumatologist measured the level of disease activity during the interval. RESULTS: Eighty-nine of the 97 patients were included in this study with a mean follow-up of 14 months. The yearly incidence of TMJ involvement was 7.1% in patients with JIA. Improvement on the OPT was seen in 27 patients (66%), and 19 of these patients no longer showed any signs of TMJ involvement. Worsening on the OPT was seen in four patients (10%). Disease activity was significantly lower in the improved patients than in the patients with worsening. CONCLUSION: Condylar lesions due to arthritis can improve over time, indicating a regenerative capacity of the mandibular condyle. As condylar improvement seems to be associated with low disease activity, it is important to consider the TMJ when deciding on a therapeutic regimen.
