Background Allergic fungal rhinosinusitis (AFRS) is the most common type of fungal diseases in nose and paranasal sinuses. It is due to hypersensitivity to fungal antigens. The standard treatment for control of AFRS is endoscopic sinus surgery followed by systemic and/or topical steroids. In spite of steroids known to have promising results for the management of AFRS, their prolonged use is not always advised. So, some authors have tried to decrease the recurrence rate of AFRS by using antifungal treatment. In this study, we compared the efficacy of local steroids (Fluticasone nasal spray) versus local steroids plus itraconazole postoperatively in the prevention of recurrence of allergic fungal sinusitis in patients known to be hypertensive or diabetic.
Patients and Methods A total of 60 patients with AFRS and nasal polyposis were included in the study. Patients were divided randomly into two groups: group A used local steroid and group B used local steroid and itraconazole. Clinical parameters were compared at the end of 6 months.
Results Patients of group B were better clinically and also by endoscopic examination.
Conclusion Itraconazole is better to be added in the postoperative treatment of AFRS patients especially for patients who have contraindications for systemic steroids intake.

| Introduction|| |
Allergic fungal rhinosinusitis (AFRS) is the most common type of fungal diseases in nose and paranasal sinuses. At the same time, it has a high recurrence rate despite numerous strategies to prevent it .
AFRS is a form of polypoid chronic rhinosinusitis that is believed to be due to hypersensitivity to fungal antigens. It is characterized by type 1 hypersensitivity to fungal allergens and elevated total serum IgE .
The standard treatment for control of AFRS is endoscopic sinus surgery followed by systemic and/or topical steroids . Although most of patients are usually improved by this treatment, recurrence was noticed in many patients even in the early postoperative period .
Steroids are known to be the main line of treatment for AFRS. However, their prolonged use especially systemic steroid is associated with many adverse effects. In addition, there are some patients who do not respond to this treatment .
So, some authors have tried to decrease the recurrence rate of AFRS by using antifungal therapy, which acts by inhibiting the fungal growth in the postoperative period with different results ,,,.
In this study, the efficacy of postoperative local steroid spray alone (Fluticasone) is compared with local steroid plus itraconazole in the prevention of recurrence of allergic fungal sinusitis in patients known to be hypertensive and/or diabetic.
| Patients and methods|| |
This prospective study was conducted in the departments of otorhinolaryngology in Beni-Suef and Fayoum universities in the period from October 2014 to October 2017. The study was approved by the ethics committee of Beni-Suef and Fayoum universities. A written informed consent was taken from all the patients.
Sixty patients with AFRS with sinonasal polyposis were included in the study. Their ages ranged between 33 and 61 years, with a mean of 43±7.3 years. Patients were known to be hypertensive and/or diabetics. Recurrent cases were excluded from the study.
Preoperative assessment included history taking, clinical examination, office-based nasal endoscopy, and routine laboratory investigations; moreover, noncontrast computed tomography (CT) on nose and paranasal sinuses was performed for all patients.
Patients were divided randomly into two groups: group A included 30 patients, and they received local intranasal steroids spray (Fluticasone) in the form of two puffs in each nostril once daily for 6 month after surgery, whereas group B included 30 patients, and they received oral itraconazole (100 mg twice daily) for 2 months plus local steroid nasal spray (Fluticasone) for 6 months after surgery. Clinical parameters were compared at the end of the sixth postoperative month.
Patients were given a course of antibiotics in the form amoxicillin–clavulanic acid 1 g twice daily and systemic antihistaminic in the form of cetirizine for 1 week before endoscopic sinus surgery to improve the condition of paranasal sinuses as a preoperative preparation.
Endoscopic sinus surgery was done for all patients. Intraoperatively, nasal swabs were taken. Cytological assessment of charcot-layden crystals, fungal hyphae, allergic mucin, eosinophils, basophil, and mast cells was done. Specimens (allergic mucin, debris, and polypi) were sent for histopathological examination.
Postoperatively, all patients received systemic antibiotic and antihistaminic for 1 week after surgery (same as preoperatively). Patients were followed up at the end of the first, second, third, and sixth postoperative month. At each visit, subjective and objective assessments were done. Subjective assessment for each symptom such as nasal obstruction, nasal discharge, headache, facial pain, nasal polypi, sneezing, itching, and hyposmia was done. Objective assessment included endoscopic examination in each visit to assess any recurrent polypi, allergic mucin, nasal discharge, mucosal edema, debris, or sinus obstruction. Moreover, CT on nose and paranasal sinuses was done at the end of the sixth postoperative month to detect any recurrence of disease. Liver enzymes were assessed in group B patients 2 months postoperatively.
| Results|| |
A total of 60 patients were enrolled in our study. In group A, 17 patients were males and 13 patients were females. Similarly in group B, 16 patients were males and 14 patients were females. Overall, 45 (75%) patients of our study population were in the age group of 33–50 years and 15 (25%) were in the age group of 51–61 years.
A total of 40 patients were suffering from disease for 1–2 years and 20 patients had a longer duration of symptoms up to 5 years. Nasal obstruction was found in all patients, nasal discharge was found in 35 patients, and headache was found in 10 patients. Patients’ preoperative symptoms are summarized in [Table 1].
There was no statistically significant difference between both groups regarding preoperative symptoms.
The characteristic heterogeneous opacity in CT scans was present in all patients. By CT scan, the affected sinuses were assessed. Overall, 60% of the patients had bilateral and 40% had unilateral affection. Ethmoid sinuses (anterior and posterior ethmoids) were affected in all cases (100%). Maxillary sinuses were affected in 39 (65%) patients, sphenoid sinuses in 20 (33.33%) patients, and frontal sinuses in 14 (23.33%) patients.
In nasal smear, eosinophil and allergic mucin were present in all patients. Fungal hyphae and charcot-layden crystals were found in six patients: two patients in group A and four patients in group B. All samples sent for histopathological assessment had nasal polyps with inflammation.
In group A, postoperatively all patients were clinically asymptomatic at the end of the first and the third month regarding nasal obstruction, nasal discharge, headache, facial pain, and nasal polypi. At the sixth month, five patients started to complain of nasal obstruction. In group B, all patients were clinically asymptomatic at the end of the sixth month postoperatively.
In group A, there was no recurrence of nasal polyps at the end of the first and the third postoperative month. At the end of sixth month, five patients started to show recurrence of nasal polyps at the region of the ethmoids. In these patients, systemic steroids were given for 3 weeks under medical supervision and polyps were resolved.
In group B, two patients had mild elevation of liver enzymes at the end of second month, which was improved spontaneously after stoppage of itraconazole. All patients were symptomatically free during the whole follow-up period (6 months). This was documented by CT scan on nose and paranasal sinuses at the end of sixth postoperative month ([Figure 1] and [Figure 2]).

| Discussion|| |
AFRS is a chronic disease with a very high recurrence rate . Recurrence occurs despite meticulous surgical removal of polyps, allergic mucin, and diseased mucosa. The exact reason for this recurrence is vague. It may be owing to re-exposure to fungi, persistent microscopic fungi not removed during endoscopic sinus surgery (ESS), or unrecognized fungal infection . There is also patient-to-patient variation in response to steroids. Some patients are well controlled with minimal steroids, whereas others are unresponsive to high doses and/or repeated courses of prednisone and topical steroids .
Treatment of AFRS is conflicting. Different treatment protocols have been adopted in the past decade to overcome recurrence of this disease. It is known that steroids whether systemic and/or topical increase the cure rates of AFRS by decreasing the recurrence with reduction of mucosal stage of the disease .
In spite of the hopeful postoperative results, a considerable proportion of the patients usually present with recurrence of disease even in the early postoperative period. This recurrence ranges from 10% to about 100% depending on the length of follow-up period ,.
Although prolonged use of high-dose systemic steroids is needed for the treatment of AFRS, this is not always possible in all patients because of its inevitable systemic toxicity.
Keeping in mind the etiological factor of AFRS, antifungal treatment has been tried in many patients with AFRS for better control of the disease and for less recurrence rate ,,,. The role of antifungal treatment in the management of AFRS is still controversial, but some studies found good results with systemic use of itraconazole .
In the current study, 60 patients having AFRS with sinonasal polyposis were included. All these patients were known to be either hypertensive and/or diabetics. Recurrent cases were excluded from the study.
Endoscopic sinus surgery was done for all patients. Intraoperatively, nasal swabs were taken. Cytological assessment was done for all patients. Specimens (allergic mucin, debris, and polypi) were sent for histopathological examination. We did not do culture and sensitivity for our patients, as many authors found that it is not conclusive, as fungi can grow as saprophytes in the affected sinus .
These patients were divided randomly into two groups (group A and group B). Each group included 30 patients. Patients of group A received local intranasal steroids spray (Fluticasone) in the form of two puffs in each nostril once daily for 6 months after surgery and patients of group B received oral itraconazole (100 mg twice daily) for 2 months plus local steroid nasal spray (Fluticasone) for 6 months after surgery. Systemic steroids were not used in both groups as the patients were either hypertensive and/or diabetic.
It was found that patients treated with local steroids and itraconazole had significant improvement in the symptoms and endoscopic examination at the end of 6 months than patients treated by local steroids alone.
In group A, there was no recurrence of nasal polyps during the follow-up period. There was mild allergic mucin during the follow-up period, which was removed by suction under endoscopic vision. However, at the end of the sixth month, five patients started to show recurrence of nasal polyps at the region of the ethmoids. In these patients, systemic steroids were given for 3 weeks. In group B, there was no recurrent polypi documented by endoscopic examination nor CT scan till the sixth postoperative month.
Chan and colleagues, also found that itraconazole was effective in a good percentage of patients of AFRS who had surgery and were refractory to prednisone, intranasal steroids, and amphotericin B nasal sprays. Of 32 patients, 12 patients were improved by using itraconazole . Itraconazole acts by inhibiting enzyme lanosterol 14-alpha-demethylase, which decreases the synthesis of ergosterol, which is a vital component of the fungal cell membrane. This reduces the fungal load in the postoperative period .
In this study, we have used itraconazole in small doses (100 mg twice daily) just for 2 month only. This avoids its major adverse effects especially the hepatic toxicity. So, elevation of liver enzymes was reported just in two patients of itraconazole group who were improved spontaneously after stoppage of itraconazole. Otherwise, no other complications occurred.
Other authors also recommended not to use antifungal treatment for prolonged period of time because of the derangement of liver enzymes, which may occur after its large therapeutic doses .
On the contrary, Rains and Mineck reported using up to 400 mg of itraconazole a day and then tapering down to 200 mg a day over 3 months without any major adverse effects. They reported only elevated liver enzymes in 4% of patients .
From this study, it is found that itraconazole is better to be added in the postoperative treatment of patients with AFRS, especially for patients who have contraindications for systemic steroids intake.
