Features of Japanese juvenile spondyloarthritis patients in our hospital

چکیده
Introduction Spondyloarthritis (SpA) is thought to be very rare in Japan, because possession rate of HLA-B27 in healthy people is 0.4% and it is significantly lower than that of other countries (5%). This makes it difficult for Japanese physicians to diagnose SpA early. Since 10-20% of SpA patients experience symptoms in their childhood, it is very important to distinguish them from other chronic arthritis patients for pediatric rheumatologists.

BACKGROUND Childhood-onset spondyloarthropathies usually start with enthesitis and peripheral arthritis. However, axial disease may develop afterward. Patients are most often classified, following revised (Edmonton 2011) ILAR criteria, as enthesitis-related arthritis, psoriatic arthritis, or unclassified juvenile idiopathic arthritis, particularly in cases of psoriasis in the patient or a first...

Introduction To understand disease mechanism and close the gap between genotype and phenotype, majority of studies today use the high-throughput methods that allow us to study genes on a global scale. One of these methods is expression profiling which generates a “snapshot” of cellular activity at the time of analysis, telling us exactly what processes are occurring. By comparing disease and co...
متن کاملImaging of juvenile spondyloarthritis. Part I: Classifications and radiographs
Juvenile spondyloarthropathies are manifested mainly by symptoms of peripheral arthritis and enthesitis. By contrast with adults, children rarely present with sacroiliitis and spondylitis. Imaging and laboratory tests allow early diagnosis and treatment. Conventional radiographs visualize late inflammatory lesions and post-inflammatory complications. Early diagnosis is possible with the use of ...
