Periodic fevers with aphthous stomatitis, pharyngitis, and adenitis (PFAPA)

Area of Science:

• Pediatrics
• Immunology
• Genetics

Background:

• PFAPA syndrome is the most frequent cause of periodic fever in pediatric patients.
• It is classified within the autoinflammatory diseases, though its etiology remains unknown due to the absence of identified genetic or molecular markers.
• Diagnosis relies on clinical criteria, posing challenges in differentiating it from other hereditary periodic fever syndromes, particularly in younger children.

Purpose of the Study:

• To review the current understanding of PFAPA syndrome.
• To discuss diagnostic challenges and differential diagnoses.
• To explore current treatment options and their controversies.

Main Methods:

• Literature review of PFAPA syndrome.
• Analysis of diagnostic criteria.
• Evaluation of therapeutic interventions.

Main Results:

• PFAPA syndrome is characterized by recurrent episodes of fever, aphthous stomatitis, pharyngitis, and cervical adenitis.
• Attacks resolve spontaneously, and the condition often resolves spontaneously over time in affected children.
• Corticosteroids can abort attacks, and tonsillectomy is a potential alternative, though its efficacy needs further clarification.

Conclusions:

• PFAPA syndrome is a common autoinflammatory disorder in children with an unknown etiology.
• Clinical diagnosis is key, but differentiation from other periodic fever syndromes can be difficult.
• Treatment options like corticosteroids and tonsillectomy are available but require further research regarding their long-term role and efficacy.
