Bronchiectasis without CF is known as non-CF bronchiectasis. Historically, about half of all case of non-CF bronchiectasis were found to be idiopathic , or without a known cause. [ 25 ] However, more recent studies with a more thorough diagnostic work-up have found an etiology in 60 to 90% of patients.
COPD is defined as a forced expiratory volume in 1 second divided by the forced vital capacity (FEV1/FVC) that is less than 0.7 (or 70%). [8] The residual volume, the volume of air left in the lungs following full expiration, is often increased in COPD, as is the total lung capacity, while the vital capacity remains relatively normal.
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production and/or exacerbations) due to abnormalities of the airways (bronchitis ...
Asthma, chronic bronchitis, bronchiectasis and chronic obstructive pulmonary disease (COPD) are all obstructive lung diseases characterised by airway obstruction. This limits the amount of air that is able to enter alveoli because of constriction of the bronchial tree, due to inflammation.
It is a form of congenital cystic bronchiectasis. This leads to collapse of the airways and bronchiectasis. [1] It acts as one of the differential to allergic bronchopulmonary aspergillosis. WCS is a deficiency of the bronchial cartilage distally. [2]
Since the medical term for conditions of unknown cause is "idiopathic", the clinical term for UIP of unknown cause is idiopathic pulmonary fibrosis (IPF). [2] Examples of known causes of UIP include connective tissue diseases (primarily rheumatoid arthritis ), drug toxicity, chronic hypersensitivity pneumonitis , asbestosis and Hermansky ...
