PFAPA syndrome (periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis) is the most common periodic fever syndrome in children. The disease appears to cluster in families, but the pathogenesis is unknown. The paper reports the description of a clinical case of a 12-year-old girl diagnosed with PFAPA syndrome from the age of one and half years. The exacerbations did not decrease with growth as it usually happens, but genital ulcers appeared associated with HLA-B51 positivity, orienting the diagnosis towards Behçet’s spectrum disorders.

Fever Attack

Fever is a common symptom in childhood and primarily suggests infectious diseases. The syndrome of periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA syndrome) is a periodic fever syndrome of unknown incidence and is not rare in childhood. In this case report, the management of a patient who was followed up for PFAPA syndrome during a fever attack is presented.

Background:Periodic fever, aphthous stomatitis, pharyngitis and adenitis (PFAPA) syndrome is the most common autoinflammatory disease in children, often grouped together with hereditary periodic fever syndromes, although its cause and hereditary nature remain unexplained.Objectives:We investigated whether a differential DNA methylation was present in DNA from peripheral blood mononuclear cells (PBMC) in patients with PFAPA versus a group of healthy young individuals.Methods:A whole epigenome analysis (MeDIP and MBD) was performed using pooled DNA libraries enriched for methylated genomic regions. Of identified candidate genes, two with most significantly different methylation leves were further evaluated with methylation specific restriction enzymes coupled with qPCR (MSRE-qPCR).Results:The analysis showed thatPIK3AP1andSPON2intronic gene regions are differentially methylated in patients with PFAPA. MSRE-qPCR proved as a quick, reliable and cost-effective method to confirm results from MeDIP and MBD.Conclusion:Our findings indicate that B cell adapter protein (BCAP) as PI3K binding inhibitor of inflammation and spondin-2 (SPON2) as a pattern recognition molecule and integrin ligand could play a role in etiology of PFAPA. Their role and impact of changed DNA methylation in PFAPA etiology and autoinflammation need further investigation.References:[1]Wekell P.
