Abstract

The prevalence and significance of bronchial hyperresponsiveness (BHR) in patients with non‐cystic fibrosis (CF) bronchiectasis remain unclear. The objective is to determine the prevalence of BHR, defined as a post‐bronchodilator forced expiratory volume in 1 s (FEV1) improvement > 10%, in children with non‐CF bronchiectasis and to assess its association with clinical, functional, and radiological characteristics.

Efficacy of Inhaled Colistin versus Oral Azithromycin in Preventing Exacerbation among Patients with Non-Cystic Fibrosis Bronchiectasis: A Retrospective Study

Background: Non-cystic fibrosis bronchiectasis (NCFB) is a chronic lung condition that causes ongoing inflammation of the airways of the lungs, multiple lung infections and progressive airway structural damage, resulting in repeated exacerbations and poor quality of life. Recurrent exacerbation should be treated with l...

Evaluating the Efficacy of Brensocatib in Non-cystic Fibrosis Bronchiectasis

Bronchiectasis is a widely recognised chronic respiratory illness classified in severity by frequency of exacerbations within the past year, percent predicted forced expiratory volume in 1 second (%FEV1), previous hospital admissions and radiological severity, among other factors. The physiological process is understoo...

Longitudinal Characterization of the Microbiological Status in Primary Ciliary Dyskinesia: An Italian Multicentre Study

Primary Ciliary Dyskinesia (PCD) is a genetic disorder characterized by respiratory infections leading to chronic airway colonization and progressive lung damage. The aim of this study is to evaluate prevalence and longitudinal changes of respiratory microbiological profile in children and young adults with PCD, and th...

[Bronchiectasis in children: An underdiagnosed disease with accessible screening and etiological assessment].

Long considered as a rare and neglected disease, non-cystic fibrosis bronchiectasis in children is now recognized as an emerging cause of chronic respiratory morbidity worldwide. Its incidence is strikingly variable, ranging from 0.2-2.3 per 100,000 children annually in high-income countries to more than 700 per 100,00...

Pulmonary alveolar proteinosis (PAP) is a rare disorder characterized by abnormal accumulation of surfactant within the alveoli, leading to impaired gas exchange and progressive respiratory symptoms. We report a 40-year-old stone grinder presenting with chronic cough, dyspnea, weight loss and hypoxemia. High-resolution...

Utility of the expiratory disproportion index in early detection of idiopathic subglottic stenosis masked by asthma.

Idiopathic subglottic stenosis (iSGS) is a rare fibrotic condition causing fixed extrathoracic airway obstruction, predominantly affecting postmenopausal women. The expiratory disproportion index (EDI), calculated as forced expiratory volume in one second (FEV1) (mL)/peak expiratory flow (PEF) (L/min), can help differe...
