Pediatric allergic fungal rhinosinusitis: optimizing outcomes.

Abstract

PURPOSE OF REVIEW\nAllergic fungal rhinosinusitis (AFRS) is a debilitating condition for children. Despite there being several reviews on this topic in the adult population, there is a paucity of reviews of AFRS in the pediatric literature. This article reviews the recent evidence of pediatric AFRS with the aim to optimize outcomes of pediatric patients with this condition.\n\n\nRECENT FINDINGS\nAFRS is clinically characterized by nasal polyposis, a type I hypersensitivity to fungal epitopes, very thick eosinophilic mucin, and peripheral eosinophilia. Pediatric AFRS has similar clinical characteristics to that in adults but is thought to have a more aggressive nature, with higher serum immunoglobulin E and more frequently bone erosion and malformation of facial bones. Diagnosis of pediatric AFRS is made by using the Bent and Kuhn s criteria developed for adult AFRS. The mainstay of treatment is surgery followed by postoperative corticosteroids. Adjunctive therapies, including topical/oral antifungal agents, allergen immunotherapy and biologics may improve outcomes in pediatric AFRS, but to date the current evidence is limited.\n\n\nSUMMARY\nTo optimize the outcome of pediatric AFRS, adequate and early diagnosis and treatment are essential. Appropriate and comprehensive endoscopic sinus surgery to open the sinuses, remove the fungal burden of disease and improve access of the sinuses to postoperative topical corticosteroid remains the standard of care.
