Abstract :

Patients with Idiopathic Pulmonary fiosis exhibit abnormal sleep architecture and increased sleep fragmentation . Studies have shown that sleep disordered eathing is prevalent in patients suffering from IPF. Our study aims to find out the prevalence of sleep disordered eathing , especially obstructive sleep apnea in IPF patients.30 willing and stable IPF patients underwent overnight attended polysomnography. Their demographic and clinical data were collected.OSA was found in 56.6% of the cases. 6 patients (20%) had mild OSA (AHI– 5–15 events/hr),7 patients (23.3%) had moderate OSA (AHI– 15–30 events/hr) and 4 patients (13.3%) had severe OSA (AHI– > 30 events /hr).Patients with OSA had disturbed sleep with poorer sleep efficiency and more arousals.Hypopneas were more frequently found. Considering the high prevalence of OSA in IPF patients in our study, it is imperative that all patients with IPF, having symptoms of sleep disturbance should be screened and evaluated by polysomnography for OSA.
