Modified pustulotic arthro-osteitis diagnostic guidance 2022 - Modified Sonozaki criteria - Secondary publication

The concept of pustulotic arthro-osteitis (PAO) was first reported by Sonozaki et al. in 1979, with diagnostic criteria (Sonozaki criteria) proposed in 1981. These criteria have served as the gold standard for PAO diagnosis for over 40 years. In recent years, there has been an increasing emphasis on maximizing the quality of life of patients with PAO. This is achieved by striving for clinical remission, structural remission, and functional remission through early diagnosis and appropriate therapeutic intervention from an early stage. This article is an English translation of a summary of the 'Modified PAO Diagnostic Guidance 2022', edited by the Japan Ministry of Health, Labour and Welfare's Research Group on improvement of medical standard and quality of life of patients with spondyloarthritis and related diseases represented by ankylosing spondylitis and the Japan Spondyloarthritis Society. This guidance is intended to be helpful to both Japanese and global communities in rheumatology and spondyloarthritis.
