To determine whether allergic fungal sinusitis is driven by an IgE-mediated type I allergic hypersensitivity response rather than an invasive fungal infection.
Compared 16 immunocompetent patients with histologically confirmed allergic fungal sinusitis and positive fungal cultures to 5 surgical control patients without AFS.
Measured specific IgE antibodies across multiple fungal antigens using a modified radioallergosorbent test (RAST), defining seropositivity as class 2 or higher.
All 16 patients (100%) with allergic fungal sinusitis tested positive via RAST to at least one fungal antigen corresponding to the family of their cultured organism.
None of the 5 control patients (0%) demonstrated RAST positivity to either dematiaceous or Aspergillus fungal antigens.
