Background:
Oral itraconazole is an antifungal that has been shown to be of benefit to patients with allergic bronchopulmonary aspergillus (ABPA). It is hypothesized that itraconazole may similarly benefit patients with allergic fungal sinusitis (AFS), a disease similar to ABPA. This study was designed to evaluate the therapeutic response of itraconazole in patients with refractory chronic fungal sinusitis who have failed maximal medical and surgical therapy.
Methods:
A retrospective chart review was performed of 23 patients with AFS and nonallergic eosinophilic fungal sinusitis treated with oral itraconazole. Charts were reviewed for patient demographics, comorbidities, allergies, fungal cultures, type of surgery performed, and amount of oral steroids used before and after itraconazole. All patients were given a 6-month dose of itraconazole (100 mg b.i.d.) when recurrence developed after surgery. Time to next recurrence, change in oral steroid use, and outcomes were noted. Liver function tests were taken at monthly intervals while on itraconazole.
Results:
Twenty-three patients, 13 men and 10 women, were started on oral itraconazole for recurrent fungal sinusitis. Nineteen patients responded to the medication with a decrease in symptoms and fungal mucin/polyps on endoscopy. Three patients had to stop because of elevated liver enzymes. In the remaining 16 patients a decrease in oral steroid use was noted. In addition, 11 of the 16 patients are disease free to date at a mean follow-up of 15.7 months. No permanent complications occurred from the use of the medication.
Conclusion:
Oral itraconazole may be of benefit to those patients with recalcitrant fungal sinusitis who have failed maximal medical and surgical therapy. Itraconazole may prolong the time to next recurrence and may enable the patient to significantly decrease or stop oral steroids.
Insights
Oral itraconazole shows promise for treating allergic fungal sinusitis (AFS) in patients refractory to other treatments. This antifungal medication may reduce symptoms, decrease oral steroid dependence, and prolong remission periods.
Area of Science:
- Otolaryngology
- Mycology
- Pharmacology
Background:
- Allergic fungal sinusitis (AFS) shares similarities with allergic bronchopulmonary aspergillosis (ABPA).
- Oral itraconazole is an established antifungal treatment for ABPA.
- This study investigates itraconazole's efficacy in refractory AFS cases.
Purpose of the Study:
- To evaluate the therapeutic response of oral itraconazole in patients with chronic fungal sinusitis.
- To assess itraconazole's impact on symptom recurrence and oral steroid use in AFS patients.
Main Methods:
- Retrospective chart review of 23 patients with AFS treated with oral itraconazole.
- Data collected included demographics, comorbidities, allergies, fungal cultures, surgical history, and steroid use.
- Patients received a 6-month course of itraconazole (100 mg b.i.d.) for recurrent disease post-surgery.
Main Results:
- Nineteen of 23 patients responded to itraconazole, showing reduced symptoms and fungal debris.
- Three patients discontinued treatment due to elevated liver enzymes.
- Of 16 patients with decreased steroid use, 11 achieved disease remission at a mean follow-up of 15.7 months.
Conclusions:
- Oral itraconazole may benefit patients with recalcitrant fungal sinusitis unresponsive to maximal therapy.
- Itraconazole can potentially extend time to recurrence and reduce or eliminate the need for oral steroids.
- No permanent complications were observed from itraconazole treatment.
