The Study of Sleep Disordered Breathing in Patients With Interstitial Lung Diseases

Completed

Brief Summary: This was a cross-sectional observational study to evaluate the prevalence and predictive factors of SDB in ILD and to analyze the relationship between polysomnography (PSG) findings, pulmonary function, disease severity, parenchymal involvement, and sleep questionnaires ESS and SBQ. This study included 69 patients who were diagnosed with diffuse parenchymal lung diseases by high-resolution computed tomography (HRCT) chest. All patients were subjected to clinical examination, HRCT, spirometry, full-night polysomnography, and echocardiography.

Recruitment & Eligibility

Inclusion Criteria

Both sexes of clinically stable ILD patients older than 18 who met the ATS/ERS criteria for an ILD diagnosis were included in the study.

Exclusion Criteria

Patients who have any anatomic upper airway obstructions such as significant nasal septal deviation, nasal polyps, conchae hypertrophy or tonsillar hypertrophy.
Patients with neurological diseases or severe psychiatric disorders.
Patients who have history of administration of any drug that has a major effect on sleep e.g. benzodiazepine, narcotic drugs ....etc.
Patients with any chronic pulmonary disease except ILD.
Total sleep time less than 4 hours on PSG.
