Immunotherapy for Allergic Fungal Sinusitis: The Second Year

Abstract

Since August 1994 we have followed a protocol of treating patients with histologically proven allergic fungal sinusitis with surgical extirpation of the involved sinuses, followed by immunotherapy using both fungal and nonfungal antigens to which hypersensitivity is demonstrated by in vitro and skin testing methods. Despite predictions to the contrary, we have encountered no evidence that these injections have worsened the condition of any patients. Rather, we have noted a marked decrease in nasal crusting in all patients, with a minimum amount of recurrent polypoid mucosa and a lessened or absent requirement for corticosteroids (systemic or topical). Two patients treated with immunotherapy required systemic corticosteroids and subsequent revision surgery for residual disease that was present before the start of immunotherapy, and they have done well since. Our experience indicates that the triad of adequate surgery, frequent follow-up and medical management, and immunotherapy with relevant fungal and nonfungal antigens represents an effective means of treating patients with allergic fungal sinusitis. Nevertheless, an even longer period of study will be necessary to provide the final answer regarding the role of immunotherapy in the treatment of allergic fungal sinusitis.
