Exhaled Breath Condensate (EBC) Assessment in Acute Exacerbation of Chronic Obstructive Pulmonary Disease (COPD)

2014-07-23 21:29:57 | BioPortfolio

Summary

This study aimed to assess airway inflammation in patients during the course of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) by serial analyses of their exhaled breath condensates (EBC).

Description

Subject recruitment

Patients who had been admitted to the Prince of Wales Hospital with AECOPD were recruited for this study. Subjects with pneumonic changes on the chest radiographs were excluded. Age and sex-matched COPD subjects at stable state (without AECOPD for at least 10 weeks) and healthy, non-smoking subjects were recruited as controls.

Collection of exhaled breath condensate (EBC) EBC was collected using the EcoScreen (VIASYS Healthcare, Conshohochen, PA, USA) according to the manufacturer's instructions. EBC was stored in 250 microL aliquots immediately at -70oC until analysis. EBC was collected on Day 5, 14, 30 and 60 after hospitalization for subjects with AECOPD. For the stable COPD patients and normal controls, EBC collection was performed once.

Measurement of TNF alpha, LTB4 and IL-8 The concentrations of TNF alpha, LTB4, and IL-8 in EBC were measured in one batch by high-sensitivity sandwich enzyme immunoassays (TNF alpha and IL-8 from BioSource International, Camarillo, CA, USA; LTB4 from Cayman Chemical Company, Ann Arbor, MI, USA) according to the manufacturers' instructions. Intra-subject repeatability of TNF alpha, LTB4 and IL-8 was assessed by collection of EBC in stable COPD subjects. EBC was collected as described above at the same time (09:00 to 10:00) on 2 consecutive days.

Medical and Biotech [MESH] Definitions

A disease of chronic diffuse irreversible airflow obstruction. Subcategories of COPD include CHRONIC BRONCHITIS and PULMONARY EMPHYSEMA.

Hypertrophy and dilation of the RIGHT VENTRICLE of the heart that is caused by PULMONARY HYPERTENSION. This condition is often associated with pulmonary parenchymal or vascular diseases, such as CHRONIC OBSTRUCTIVE PULMONARY DISEASE and PULMONARY EMBOLISM.

A subcategory of CHRONIC OBSTRUCTIVE PULMONARY DISEASE. The disease is characterized by hypersecretion of mucus accompanied by a chronic (more than 3 months in 2 consecutive years) productive cough. Infectious agents are a major cause of chronic bronchitis.

A scopolamine derivative and CHOLINERGIC ANTAGONIST that functions as a BRONCHODILATOR AGENT. It is used in the treatment of CHRONIC OBSTRUCTIVE PULMONARY DISEASE.
