Dupilumab improves sleep quality in chronic rhinosinusitis with nasal polyps.

PURPOSE: Chronic rhinosinusitis with nasal polyps (CRSwNP) often alters sleep quality. Dupilumab emerged as an innovative and effective therapy for refractory/recurrent severe CRSwNP. The aim of this observational retrospective study was to evaluate the sleep quality in patients with CRSwNP who underwent treatment with dupilumab.

MATERIALS AND METHODS: Forty-five patients treated with dupilumab for CRSwNP were enrolled. Clinical parameters (age, sex, comorbidities, Nasal Polyp Score - NPS, Asthma Control Test - ACT), nasal cytology, quality of life (Sino Nasal Outcome Test 22 - SNOT-22), sleep quality (Pittsburgh Sleep Quality Index - PSQI, Epworth Sleepiness Scale - ESS), and risk of sleep apnea (STOP-BANG) were recorded before treatment (T0), and after 3 (T1), 6 (T2), and 12 months (T3).

RESULTS: NPS, ACT and SNOT-22 total score improved during treatment (p < 0.05). Meanwhile, all sleep parameters evaluated with SNOT-22, ESS and PSQI improved over time (p < 0.001), expect for PSQI Use of sleeping medications. Indeed, sleep drugs are rarely used before and during the treatment. The global sleep quality was classified as poor in 88.9 % of cases at T0 and decreased to 5.7 % at T3. A high risk of sleep apnea was revealed by the STOP-BANG in 68.9 % of cases at T0 and 2.8 % of patient at T3 (p < 0.001).

CONCLUSIONS: Dupilumab improves the sleep quality and reduce the risk of sleep apnea in patients with severe CRSwNP. Its favorable effect occurs within 3 months and is maintained during the treatment.
