ABSTRACT
BACKGROUND:
Sleep-disordered breathing (SDB) and disturbed sleep are common, often underrecognized, comorbidities in people with cystic fibrosis (pwCF).OBJECTIVES:
We studied the effect of CFTR triple combination therapy elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) on sleep in pwCF.METHOD:
This was a prospective, observational sleep study in clinically stable adult pwCF. All participants underwent overnight polysomnography (PSG), before (T0) and after (T1) initiation of CFTR modulator therapy with ELX/TEZ/IVA. In addition, pulmonary function tests, calculation of BMI, and sweat chloride testing were performed.RESULTS:
Twenty-nine pwCF (mean age 32 ± 8 years; 15 female) participated in the study. Mean time between T0 and T1 was 194 ± 21 days. Total sleep time (TST) was 298 ± 40 min, with decreased sleep efficiency (SE) (76 ± 109) and increased sleep latency (SL) (73 ± 38 min). Sleep stages for NREM (N1-3) and REM sleep were within the normal range. Nocturnal respiratory events mainly occur during REM sleep (T0 AHI REM 8.3 ± 9.0/h; ODI REM 9.4 ± 10.6/h), whereas the overall AHI was normal (3.6 ± 3.7/h). After initiation of ELX/TEZ/IVA, we saw significant improvements in ppFEV1 (p < 0.001) and BMI (p < 0.001) and a reduction in sweat chloride levels (p < 0.001). In parallel, there was a reduction in AHI (p = 0.003), ODI (p = 0.001), and nocturnal respiratory rate (p < 0.001), both in total, REM and NREM sleep. Neither TST, SL, SE, nor sleep architecture was influenced (all p > 0.05).CONCLUSIONS:
Initiation of ELX/TEZ/IVA resulted in significant improvements in SDB in adult pwCF.Palavras-chave
