ABSTRACT
INTRODUCTION:
The Sino-Nasal Outcome Test 22 (SNOT-22) is an important tool in assessing the quality of life (QoL) of patients with chronic rhinosinusitis with a validated version in Brazil. The eosinophilic nasal polyposis (ENP) represents most of the cases of nasal polyposis (85-90%) and belongs to the group of chronic rhinosinusitis. It is a chronic inflammatory disease that impacts the QoL of patients, not only causing localized symptoms, but also resulting in a general malaise. The standard treatments (corticosteroids and nasal endoscopic surgery) lead to partial control of symptoms, but relapses are frequent. Macrolide acting as an immunomodulator is a promising tool for more effective control of this disease. Studies are still lacking to assess the real impact on the QoL in patients treated with macrolides.
OBJECTIVE:
To evaluate the improvement of QL, evaluated using SNOT-22, in patients with PNSE treated with immunomodulatory dose azithromycin.
METHODS:
This is a paired experimental study in patients with ENP. Comparison of pre-treatment and post-treatment with azithromycin was performed. Patients completed the SNOT-22 questionnaire before the start of treatment and returned for evaluation after eight weeks of treatment. Azithromycin was prescribed at a dose of 500 mg, orally, three times a week, for 8 weeks.
RESULTS:
SNOT-22 score decreased 20.3 points on average. There was a significant decrease in the SNOT-22 (difference greater than 14 points) in 19 patients (57.6%). There was no significant difference in improvement in SNOT in subgroups with or without asthma/aspirin intolerance.
CONCLUSION:
Azithromycin resulted in significant improvement of QoL, assessed by SNOT-22, in the studied population.
