Sleep Quality in Patients With Non-cystic Fibrosis Bronchiectasis

In Egypt, bronchiectasis is a frequent clinical problem seen across tertiary hospitals. Recent tertiary-center studies from Upper Egypt (including Asyut) have described the prevalence and early outcomes of bronchiectasis among admitted adults, underscoring its local clinical significance. However, despite multiple Egyptian works on sleep quality in other respiratory conditions (e.g., COPD) using the PSQI, there remains a clear evidence gap regarding sleep quality specifically in adult non-CF bronchiectasis. International cohorts consistently demonstrate prevalent sleep disturbance in bronchiectasis and links to clinical severity, but Egyptian data in non-CF adult bronchiectasis are scarce. Locally contextualized evidence is needed to understand whether sleep impairment in our patients aligns with international observations and how it relates to spirometric function, structural disease burden, composite severity indices, and inflammatory biomarkers within an Upper Egypt setting. Our study aims to Quantify sleep quality using the PSQI in adults with non-CF bronchiectasis attending Asyut University Hospitals, and Evaluate its correlations with clinical parameters (symptoms, exacerbations, mMRC, Quality of Life)
