Early Sacroiliitis in Ankylosing Spondylitis:MRI Correlated to Clinical and Laboratory Findings / 实用放射学杂志

ABSTRACT

Objective To analyze the correlation between the early sacroiliitis in ankylosing spondylitis(AS) and clinical and laboratory parameters.Methods 39 patients with AS corresponding to the modified New York criteria for AS(0-Ⅲ)were included.According to pain score(BASDAI),the patients were divided into three groups,that were static group,suspicious active group and active group.The patients were examined by MRI and laboratory including erythrocyte sedimentation rate(ESR) and C-reactive protein(CRP).The severity of activity of sacroiliac joint(SIJ) inflammation was evaluated using spondyloarthritis research consortium of Canada(SPARCC)score,comparative analysis was done among these three groups.Results There was significant differences among these three groups in SPARCC score(P0.05).The spearman correlation coefficient between SPARCC score and BASDAI score was rs=0.503,P0.05.Conclusion In early sacroiliitis of AS,the SPARCC score of SIJ lesions is positively correlated with the severity of BASDAI,but there is no correlation between the SPARCC score and ESR,CRP.
