Catching breath: monitoring airway inflammation using exhaled breath condensate

Catching breath: monitoring airway inflammation using exhaled breath condensate.

A irway inflammation plays a key role in asthma, chronic obstructive pulmonary disease (COPD) and other airway diseases. Noninvasive methods as tools to study these inflammatory processes and to monitor airway diseases are in high demand. This has lead to the rediscovery of sputum analysis and sputum induction as noninvasive tools to obtain samples from the airways [1]. Around this time increas...

Exhaled breath condensate pH

In a previous issue of the European Respiratory Journal STEVENS et al. [1] suggested that preschool children with wheeze account for a significant proportion of the UK healthcare budget. Most preschool wheezing is caused by viral infection and, therefore, we wondered how much preschool children with upper respiratory tract infection (URTI) without wheeze would cost the National Health Service? ...

Exhaled Breath Condensate

Objective: To examine exhaled breath condensate levels of 8-iso-PGF2ot as a noninvasive quantification of pulmonary oxidant stress in patients with, or at risk for, ARDS/ALI. Methods: Breath condensate was collected from 22 patients with, or at risk for, ARDS/ALI by placing Tygon tubing submerged in an ice bath in line with the expiratory limb of the ventilator circuit. Ten patients without lun...
