Cystic Fibrosis (CF) presents multiorgan manifestations that include chronic rhinosinusitis (CRS) with or without nasal polyposis. Nasal washes (NWs) are widely used in clinical practice especially in CF patients, although their effectiveness on Ear Nose Throat (ENT) symptoms is controversial. In this study we evaluate the performance and the safety of a NWs solution, with or without surfactant, to reduce symptoms and bacterial load. Materials and methods We enrolled 20 CF patients (mean age: 27,6 years) with CRS, confirmed by nasal endoscopy. All patients, colonized by Pseudomonas Aeruginosa, performed daily a NW by physiological solution or by saline solution with surfactant (Naridek). All patients, at the time of enrollment, filled out a sinonasal questionnaire (SANQ11) and they received instructions for proper washing.

Abstract

Cystic Fibrosis (CF) presents multiorgan manifestations that include chronic rhinosinusitis (CRS) with or without nasal polyposis. Nasal washes (NWs) are widely used in clinical practice especially in CF patients, although their effectiveness on Ear Nose Throat (ENT) symptoms is controversial. In this study we evaluate the performance and the safety of a NWs solution, with or without surfactant, to reduce symptoms and bacterial load. Materials and methods We enrolled 20 CF patients (mean age: 27,6 years) with CRS, confirmed by nasal endoscopy. All patients, colonized by Pseudomonas Aeruginosa, performed daily a NW by physiological solution or by saline solution with surfactant (Naridek). All patients, at the time of enrollment, filled out a sinonasal questionnaire (SANQ11) and they received instructions for proper washing. During follow-up, we evaluated the reduction of the bacterial load in the nasal lavage. We assess the nasal cavities by endoscopy (2.7 mm 30° rigid endoscope - Storz, Tuttlingen, Germany) according to a modified Lund Kennedy endoscopic scoring system: - rhinorrhea (present = 0, mild = 1, purulent = 2); - edema, and hyperemia (absent = 0, mild = 1 or severe =2) - nasal mucosa (eutrophic = 1; hyperemic = 2; dystrophic = 3); - left and right turbinate hypertrophy (none = 0; mild = 1; medium = 2; and serious = 3). All subjects underwent the Sniffin’Sticks to evaluate the olfactory performance. Results Twelve patients completed 4 months of treatment: 6 patients performed the treatment with Naridek and 6 patients with physiological solution. Due to the small sample size, the scores were added together to have an overall indication of the treatment. (Table1) Nasal endoscopy ENT signs score Olfactory performance SNAQ 11 Naridek V1 80 72* 169 197** Naridek V4 15* 15* 159 98** Physiological solution V1 68 61 151 166 Physiological solution V4 52 39 159 152 *P<0.05 ** p< 0,01 The bacterial colonization in NWs shows no statistically significant difference.
