Abstract

Background: Recurrent tonsillitis is a common indication for tonsillectomy in children and has phenotypic overlap with periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome. We sought to characterize symptoms associated with PFAPA among children undergoing tonsillectomy.

Methods: Parents/guardians of children undergoing tonsillectomy at Vanderbilt Children's Hospital over a six-week period were queried regarding symptoms of recurrent fever. Follow-up questionnaires were administered 3 and 12 months after tonsillectomy.

Results: 82% (120/147) of patients who underwent tonsillectomy during the study period participated. Provider-documented indications for tonsillectomy were obstructive sleep apnea in 88% and recurrent tonsillitis in 33%. 11% (13/120) reported[Formula: see text]6 episodes of stereotypical fever in a one-year period. During febrile episodes among these 13 subjects, 11 had tonsillitis, 5 had cervical adenitis, 3 had aphthous stomatitis, and three reported regular and predictable episode timing. In addition, participants with ≥3 episodes/year of recurrent febrile tonsillitis (N = 33) had a significantly higher prevalence of recurrent aphthous ulcers than those without recurrent tonsillitis (24% vs. 9%, p = 0.04). All participants, including those with recurrent fever, reported fewer febrile tonsillitis episodes one year after tonsillectomy.

Conclusions: In our survey of children undergoing tonsillectomy, a subpopulation had frequent, stereotypical fever episodes with recurrent tonsillitis, aphthous stomatitis, or regular timing like patients with PFAPA. Although we cannot diagnose such patients with PFAPA in this limited retrospective study, pediatricians and otolaryngologists evaluating patients for tonsillectomy should be aware of the clinical signs of PFAPA that may warrant additional evaluation and therapeutic approaches.
