Abstract
BACKGROUND
Chronic rhinosinusitis is common in cystic fibrosis (CF), as CFTR defects equally affect the airway and sinonasal mucosa. However, therapeutic strategies for CF-associated chronic rhinosinusitis lag behind current approaches for pulmonary disease.
OBJECTIVE
To assess the tolerability and efficacy of a nasal spray formulation containing 0.2% sodium hyaluronate and 3% tobramycin compared to a control formulation containing 0.2% sodium hyaluronate alone in the treatment of bacterial rhinosinusitis in patients with CF.
METHODS
In a double-blind controlled study, 27 patients with an established diagnosis of CF and a documented nasal infection with Pseudomonas aeruginosa and/or Staphylococcus aureus [22 males (81%), median age of 15 years (range 5-26 yrs)], were randomized to receive the nasal spray formulation containing hyaluronate and tobramycin (N=14) or hyaluronate alone (N=13) for 14 days. Efficacy and local tolerability of the treatments were assessed by ear, nose and throat (ENT) examination and related symptoms.
RESULTS
The formulation containing hyaluronate and tobramycin was more effective than hyaluronate alone in improving the status of the nasal mucosa, in reducing the mucopurulent secretion at the level of the osteomeatal complex and in improving ENT symptoms (hyposmia/anosmia and headache/facial pain). The treatment was well tolerated without relevant side effects.
CONCLUSIONS
The present study suggests that the combination therapy with hyaluronate plus tobramycin was more effective than hyaluronate alone in the treatment of bacterial rhinosinusitis in CF.
