Background: With increasing focus on patient-reported outcome measures (PROMs) in chronic rheumatic diseases, we aimed to evaluate the self-reported physical and psychosocial health in children with juvenile idiopathic arthritis (JIA) compared to matched population-based controls. Furthermore, we aimed to study the association of patient- and physician-reported outcome measures in JIA with patient-reported physical disability.
Methods: We used data from a Norwegian JIA cohort study (NorJIA), including clinical characteristics and outcome measures in participants with JIA and sex- and age-matched population-based controls.
Objective: To assess the agreement between child- and parent-reported orofacial symptoms in the Danish version of the patient questionnaire Assessment of Orofacial Symptoms in Juvenile Idiopathic Arthritis.
Method: This cross-sectional study was conducted at Aarhus University in March 2023. Eligible candidates were consecutive subjects with juvenile idiopathic arthritis (JIA) and temporomandibular joint involvement accompanied by a parental proxy for examination in the Craniofacial Clinic.
Objective: We aimed to investigate the incidence of juvenile idiopathic arthritis (JIA) in the three geographic regions of Norway and whether potential regional incidence differences are explained by environmental or genetic factors across regions.
Methods: We conducted a register-based cohort study including all Norwegian children born from 2004 to 2019, with follow-up throughout 2020. The JIA diagnosis, defined by at least two International Classification of Diseases, Tenth Revision codes for JIA, was validated against medical records.
Objectives: To assess the ability of baseline serum biomarkers to predict disease activity and remission status in juvenile idiopathic arthritis (JIA) at 18-year follow-up (FU) in a population-based setting.
Methods: Clinical data and serum levels of inflammatory biomarkers were assessed in the longitudinal population-based Nordic JIA cohort study at baseline and at 18-year FU. A panel of 16 inflammatory biomarkers was determined by multiplexed bead array assay.
