A clinical review of 105 patients with PFAPA (a periodic fever syndrome).

Feder HM, Salazar JC
Acta paediatrica (Oslo, Norway : 1992) •

We describe the presentations and clinical outcomes of pediatric patients diagnosed with PFAPA (Periodic Fever, Aphthous lesions, Pharyngitis, and cervical Adenitis). The medical records of children with recurrent fever and referred between 1998 and 2007 to a tertiary pediatric care hospital were reviewed. Children who met clinical criteria for PFAPA were then asked to participate in a follow-up study. One hundred and five children met study criteria for PFAPA which included at least six episodes of periodic fever. Most (62%) were males, the mean age at onset of PFAPA was 39.6 months (80% were <5 years at onset), the mean duration of individual fever episodes was 4.1 days, and the mean interval between episodes was 29.8 days. Accompanying signs and symptoms included aphthous stomatitis (38%), pharyngitis (85%), cervical adenitis (62%), headache (44%), vomiting with fever spikes (27%) and mild abdominal pain (41%). A prodrome (usually fatigue) preceded the fever in 62% of patients. Parents noted that when their child with PFAPA had fever, other family members remained well. Laboratory tests in patients with PFAPA were nonspecific. Individual episodes of fever usually resolved with a single oral dose ( approximately 1 mg/kg) of prednisilone. The interval between fever episodes shortened in 50% of patients who used prednisilone. PFAPA resolved spontaneously (mean length 33.2 months) in 211105 (20%) patients. PFAF'A episodes continued (mean length 23 months) at the end of this study in 661105 (63%) patients. Cimetidine therapy was associated with the resolution of the fevers in 7/26 (27%) patients; tonsillectomy was associated with the resolution of the fevers in 11/11 (100%) patients. PFAPA can usually be defined by its clinical characteristics. Individual febrile episodes usually resolve dramatically with oral prednisilone. The cause of PFAPA is unknown and research is needed to define its etiology. The overall prognosis for children with PFAPA is excellent.

Periodic fever, aphthous stomatitis, pharyngitis, adenitis: a clinical review of a new syndrome.

Feder HM
Current opinion in pediatrics •

Periodic fevers (fevers that occur predictably at fixed intervals) are unusual in infants and children. The classic periodic fever syndrome is cyclic neutropenia (neutropenia followed by infections and fever that recur every 21 days). A new periodic fever syndrome PFAPA (periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis) has been characterized over the past decade. PFAPA is defined clinically, because specific laboratory abnormalities have not been found. The clinical characteristic of PFAPA is high fevers (usually 40.0 degrees C to 40.6 degrees C) recurring at fixed intervals every 2 to 8 weeks. The fevers last for about 4 days, then resolve spontaneously. Associated with the fevers are aphthous stomatitis in 70% of patients, pharyngitis in 72% of patients, and cervical adenitis in 88% of patients. PFAPA is not familial and begins before the age of 5 years. An episode of PFAPA can be aborted with one or two small doses of prednisone. The episodes of PFAPA may last for years and the patient is well between episodes. The cause of PFAPA is unknown and there are no reported sequelae.
