Sleep disordered breathing and airway disease in primary ciliary dyskinesia
Background and objective Sleep-disordered breathing (SDB) may develop in primary ciliary dyskinesia (PCD), leading to these diseases worsening one another. Methods Sixteen stable PCD patients (4. 9-17. 2 years) and 42 controls underwent overnight respiratory polysomnography (rPSG) and Sleep Disturbances Scale for Children (SDSC). In PCD we assessed nasal endoscopy, pulmonary function tests and chest high-resolution computed tomography (HRCT). Results Compared with controls, PCD had higher obstructive apnoea (4. 7 vs 0. 2, P < 0. 001), central apnoea (0. 8 vs 0. 2, P < 0. 001), hypopnoea (1. 8 vs 0. 2, P < 0. 001), apnoea-hypopnoea (7. 8 vs 0. 6, P < 0. 001), oxygen desaturation indexes (ODI; 0. 7 vs 0. 2, P = 0. 002), and mean oxygen desaturation (4% vs 1%, P < 0. 001), while mean and nadir oxygen saturation (97. 1% vs 98. 1, P < 0. 001) (93% vs 97. 2%, P < 0. 001) were lower, respectively. In PCD, SDSC was unrelated to rPSG (P > 0. 05), with total score and subscores of disorders in initiating and maintaining sleep, and sleep-wake transition lower than controls. PCD patients had chronic rhinosinusitis (100%) and adenoidal hypertrophy (50%). Total HRCT score was 7 (range 0-14). ODI correlated with functional residual capacity (r = 0. 8, P = 0. 02), total HRCT (r = 0. 6, P = 0. 03) and peribronchial thickening scores (r = 0. 7, P = 0. 02). Oxygen saturation was associated with bronchiectasis severity score (r = -0. 6, P = 0. 02). Conclusions PCD's parents may underestimate SDB. As nocturnal desaturation is associated with lung function and structure abnormalities, SDB may significantly contribute to pulmonary morbidity. 2014 The Authors.
