Association of the 2022 ACR/EULAR Classification Criteria for Eosinophilic Granulomatosis With Polyangiitis With Disease Activity and Damage Accrual: A Retrospective Cohort Study

Key Points

• This study aims to explore the relationship between AECC scores and disease activity and damage in eosinophilic granulomatosis.
• Utilized retrospective cohort analysis
• Assessed AECC scores at diagnosis
• Evaluated associations with disease activity and damage accrual
• Higher AECC scores at diagnosis correlated with greater disease activity
• Increased AECC scores related to more damage accrual over time
• Findings suggest the need for further evaluation of classification scores' clinical implications
