Abstract:
OBJECTIVE: The aim of this study is to investigate the association of different subgroups of juvenile rheumatoid arthritis (JRA) with human leukocyte antigen (HLA) class II DR alleles. METHODS: One hundred and nineteen Korean juvenile rheumatoid arthritis patients were classified as HLA-DRB1 allele. To assess the frequency, phenotype frequencies of all JRA cases and each subtypes were compared to those of 485 adult controls. RESULTS: HLA-DRB1*01 was associated with increased risk of JRA. Furthermore, DRB1*01 was associated with polyarticular JRA and pauciarticular JRA. The frequencies of DRB1*14 and DRB1*15 were higher in systemic JRA patients than the controls. CONCLUSION: The data of this study on Korean children with JRA suggests that HLA-DRB1*01 was associated with the susceptibility of JRA. The study should be extended to include larger numbers of patients.
