We read with great interest the article by Gattorno et al proposing a new set of criteria for the classification of autoinflammatory recurrent fevers.1 This year’s Paediatric Rheumatology INternational Trials Organisation(PRINTO) criteria are the third set of criteria for periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) syndrome in 3 years.1–3 While these three different sets share common points, they also include distinct clinical features, thus resulting in discrepancies in the classification of patients.

非单基因周期性发热成人是否需要 PFAPA 综合征？
