Abstract

Background: Allergic fungal rhinosinusitis (AFRS) is a distinct type of chronic polypoid rhinosinusitis that affects atopic individuals. The incidence worldwide ranges from 5% to 10%, with geographic variation in epidemiology. It imposes a significant negative impact on quality of life, concomitantly generating socioeconomic losses. Failure to remove all sinus disease increases the likelihood of relapse; thus, the best outcome is achieved through coordinated medical-surgical care. The antifungal activity of itraconazole in addition to standard steroid therapy may provide greater relief to patients with AFRS following functional endoscopic sinus surgery (FESS) by decreasing the chances of recurrence and long-term use of steroids. Therefore, this study has been taken up.

Aim and Objectives: The aims and objectives of the study are to evaluate the efficacy of oral itraconazole as an add-on to the standard steroid therapy in allergic fungal rhinosinusitis from baseline to 6 weeks.

Materials and Methods: This study was conducted among 60 patients who underwent FESS and were administered medications postoperatively. The efficacy was measured by the sinonasal outcome test-20 score, the nasal endoscopic grade, and the Lund and Mackay score from baseline to 6 weeks. Continuous data were analyzed using the unpaired t-test, repeated measure analysis of variance, and paired t-test, whereas categorical data were analyzed using the Chi-square test.

Results: Comparable efficacy was observed between the group treated with standard steroids alone and the group receiving a combination of standard steroids and itraconazole. No significant improvement was seen with oral itraconazole as an add-on therapy when compared with standard steroids at the end of 6 weeks.

Conclusion: Oral itraconazole as an add-on therapy will reduce the chances of recurrence such as steroids, but in this study, there was no statistically significant reduction. The disease has a long natural course, and further follow-up is needed to establish the importance of itraconazole.
