Clinical Trial Summary

The objectives of this research grant are to determine the association of hypoxia with the severity of osteoporosis in the patients with bronchiectasis and whether the mechanism of inflammation is triggered by inflammasones, which makes it more prone to osteoporosis in patients with bronchiectasis.


Clinical Trial Description

80 patients with proven bronchiectasis, diagnosed by high-resolution computed tomography (HRCT), will be recruited from our outpatient clinic of Chang Gung Memorial Hospital with written informed consent. Inclusion criteria are: daily sputum > 10 ml; absence of asthma or other unstable systemic diseases; and "steady-state" bronchiectasis (< 10% alteration of 24 h sputum volume, FEV1, and FVC, and in the absence of deterioration in respiratory symptoms at baseline visits). Exclusion criteria include: unreliable clinic attendance; regular user of inhaled or oral corticosteroids; history of lung resection and known asthma defined according to American Thoracic Society guidelines.

The lung function and desaturation will be assessed by six-minute walking tests and the severity of disease will be evaluated by HRCT scores. Peripheral blood sample (40ml/person) is performed to analyze the bone turnover markers and the level of Hif in PBMC. ;
