Development and preliminary validation of the MRI scoring methods for the hip in juvenile idiopathic arthritis
摘要
Abstract
Objective:To evaluate and develop MRI scoring system for the hip in juvenileidiopathicarthritis.Materials and Methods:WeusedWanfangandPubMed to identify relevant published articles. We proposed a new MRI scoring method for the hip in JIA based on relevant articles. Retrospective studies of 92 JIA patients with hip involvement were analysed from January 2011 to June 2014. The intra-reader and inter-reader agreement (evaluated by intra-class correlation coefficients, ICCs) were determined for scores of MRI. Results:Only 5 literatures were qualified. Except joint effusion and total scores, Other lesions of developed MRI scoring method had good reliability, ICC>0.60, P>0.05. We got reversible and irreversible MRI signs. Reversible MRI signs:synovial hypertrophy, joint effusion, bone edema. Irreversible MRI signs: bony erosion, cartilage loss, epiphysis lesion, joint space narrowing, muscular inflammation. There was no differences between subtypes of JIA in hip MRI scorings, oligoarticular JIA scorings were 6 (0—17), systemic JIA scorings were 5 (0—21), polyarticular (rheumatoid factor negative) scorings were 7 (1—19), polyarticular (rheumatoid factor positive) scorings were 8 (1—15), enthesitis related JIA scorings were 4 (2—5). Arthritis or subclinical-arthritis of hips could be detected much earlier. Especially in history of arthritis of 4 or fewer joints group (χ2=16.80, P<0.01) and in history of arthritis of 5 or more joints group (χ2=4.792, P=0.029). Conclusions:Developed MRI scoring method proved to be a simple and highly reliable assessment score in the evaluation of JIA disease of the hips.关键词
