- Objective. We investigated associations of HLA-B27 with clinical manifestations and longterm outcome in a near population-based setting among patients with juvenile idiopathic arthritis (JIA). Methods. We studied clinical and serological data from 410 patients with HLA-B27 results among 440 prospectively collected patients with JIA with 8-year followup data in a Nordic database. The study was structured to be as close to a population-based study as possible. Results. HLA-B27 was analyzed in 93% of patients, and was positive in 21% of the cohort, in 18.4% of the girls and in 25.9% of the boys. Boys who were HLA-B27-positive had significantly higher age at onset compared to HLA-B27-negative boys and compared to both HLA-B27-negative and positive girls. This difference in onset age in relation to HLA-B27 was not found in girls. HLA-B27 was associated with clinical signs of sacroiliitis, enthesitis, and tenosynovitis in boys, but not in girls. After 8 years of disease, 46 children (11.2%) were classified as having enthesitis-related arthritis (ERA). Boys with ERA had clinical signs of sacroiliitis more often than girls with ERA. HLA-B27-positive children, as well as children with clinical signs of sacroiliitis, enthesitis, and hip arthritis, had higher odds of not being in remission off medication after 8 years of disease. Conclusion. In this near population-based Nordic JIA cohort we found significant differences between HLA-B27-positive boys and girls in age at disease onset, clinical signs of sacroiliitis, and ERA classification. HLA-B27 was negatively associated with longterm remission status, possibly because of its association with clinical disease characteristics, such as sacroiliitis, rather than being a general marker of persistent disease.

Long-term Outcomes of Temporomandibular Joints in Juvenile Idiopathic Arthritis.

Journal article (peer-reviewed)abstract
- To determine the prevalence of orofacial symptoms, dysfunctions, and deformities of the temporomandibular joint (TMJ) in juvenile idiopathic arthritis (JIA) 17 years after disease onset.Drawn from a prospective, population-based Nordic JIA cohort with disease onset from 1997-2000, 420 consecutive cases were eligible for orofacial evaluation of TMJ involvement. The follow-up visit included demographic data, a standardized clinical orofacial examination, and fullface cone-beam computed tomography (CBCT). For comparison, 200 age-matched healthy controls were used.Of 420 eligible participants with JIA, 265 (63%) were included (mean age 23.5 ± 4.2 years) and completed a standardized clinical orofacial examination. Of these, 245 had a full-face CBCT performed. At least one orofacial symptom was reported by 33%. Compared to controls, the JIA group significantly more often reported TMJ pain, TMJ morning stiffness, and limitation on chewing. Furthermore, among participants reporting complaints, the number of symptoms was also higher in the JIA. The mean maximal incisal opening was lower in the JIA group (p<0.001), and TMJ pain on palpation was more frequent. Condylar deformities and/or erosions were observed in 61% as assessed by CBCT, showing bilateral changes in about 70%. Risk factors of condylar deformities were orofacial dysfunction or biologic treatment; enthesitis-related arthritis was protective.This first study on long-term consequences of TMJ involvement in a population-based JIA cohort reports persistence of comprehensive symptoms, dysfunctions, and damage of the TMJ into adulthood. We suggest interdisciplinary follow-up of JIA patients also in adulthood.

Biomarkers of Chronic Uveitis in Juvenile Idiopathic Arthritis : Predictive Value of Antihistone Antibodies and Antinuclear Antibodies
- 2009
-
In: Journal of Rheumatology. - : The Journal of Rheumatology. - 0315-162X .- 1499-2752. ; 36:8, s. 1737-1743
-
Journal article (peer-reviewed)abstract
- Objective. To study the predictive value of antinuclear autoantibody (ANA) tests and antihistone antibodies (AHA) as risk factors for development of chronic asymptomatic uveitis of insidious onset in juvenile idiopathic arthritis (RA). Methods. ANA by indirect immunofluorescence using HEp-2 cells (IF-ANA), ELISA for ANA (E-ANA), and AHA were analyzed in sera of 100 children with recent-onset JIA and in 58 control sera. Clinical features, including age at onset, JIA subgroup, and presence Of Uveitis, were recorded in this prospective population-based cohort study. Results. E-ANA was positive in 4 of the 100 sera, and was not associated with uveitis. Chronic uveitis developed in 16 children with JIA: in 14 of 68 positive for IF-ANA : 80, and in 13 of 44 positive for AkA >= 8 U/ml. IgM/IgG AHA were found in higher proportions in children with uveitis (mean 12.4 U/ml) than in those with JIA and no uveitis (mean 6.9 U/ml) or in healthy controls (mean 4.3 U/ml). Conclusion. No association was found between E-ANA and uveitis, and most IF-ANA-positive sera were E-ANA-negative. E-ANA is not clinically relevant in this setting and should never be used to determine frequencies of eye examinations to detect new uveitis in JIA. AHA >= 8 U/ml, IF-ANA titer 320, and young age at onset of arthritis were significant predictors for development of chronic uveitis. The diagnostic value of AHA 8 U/ml as a biomarker of chronic uveitis in JIA is very similar to IF-ANA >= 80. (First Release July 1 2009; J Rheumatol 2009:36:1737-43; doi: 10.3899/jrheum.081318)

Standardizing Terminology and Assessment for Orofacial Conditions in Juvenile Idiopathic Arthritis : International, Multidisciplinary Consensus-based Recommendations
- 2019
-
In: Journal of Rheumatology. - : Journal Of Rheumatology Publishing Co., Ltd.. - 0315-162X .- 1499-2752. ; 46:5, s. 518-522
-
Journal article (peer-reviewed)abstract
- Objective. To propose multidisciplinary, consensus-based, standardization of operational terminology and method of assessment for temporomandibular joint (TMJ) involvement in juvenile idiopathic arthritis (JIA). Methods. Using a sequential expert group-defined terminology and methods-of-assessment approach by (1) establishment of task force, (2) item generation, (3) working group consensus, (4) external expert content validity testing, and (5) multidisciplinary group of experts final Delphi survey consensus. Results. Seven standardized operational terms were defined: TMJ arthritis, TMJ involvement, TMJ arthritis management, dentofacial deformity, TMJ deformity, TMJ symptoms, and TMJ dysfunction. Conclusion. Definition of 7 operational standardized terms provides an optimal platform for communication across healthcare providers involved in JIA-TMJ arthritis management.
