[Diagnosis and management of periodic fever with aphthous pharyngitis and adenitis (PFAPA)].
PFAPA is non-hereditary syndrome characterized by periodic episodes of high fever, aphthous stomatitis, pharyngitis and cervical adenitis. It manifests usually in early childhood, especially before 5 years of age, and last for several years. Its etiology is unknown, but some recent reports suggest a dysregulation of the immune response with continuous pro-inflammatory cytokine activation and a reduced anti-inflammatory response both during and between febrile attacks. The diagnosis is clinical and it is important to exclude other entities of similar presentation with periodic fever and orofacial manifestations. The findings of laboratory are unspecified and show only nonspecific acute inflammatory response. Several treatments have been performed but with various results. Most effective therapy for a fast resolution of the symptoms is one or two doses of oral prednisone, but its efficacy is not permanent. Effectiveness of cimetidine and tonsillectomy in PFAPA is not clear as yet. PFAPA is a benign syndrome and the prognosis is better than other autoinflammatory syndromes, because PFAPA patients grow normally and symptoms diminish within a few years.
