From paediatric to adult care in Still's disease: addressing barriers and proposing a transition model for Italy

Still’s disease is a rare, idiopathic, systemic autoinflammatory disorder characterised by spiking fevers, evanescent rash, arthritis and elevated ferritin levels. Historically, it was considered as two distinct diseases, namely systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still’s disease (AOSD). However, these conditions now represent a continuum of Still’s disease, distinguished by age at onset.
