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? ...

متن کاملValidation of assays for inflammatory mediators in exhaled breath condensate.
The use of exhaled breath condensate (EBC) as a tool for noninvasive assessment of lung inflammation is becoming commonplace. Many authors use commercial ELISA kits to measure inflammatory mediators within EBC. However, the very low concentrations of mediators within EBC are often below the commercially validated concentration range of the relevant ELISA and crucially below the linear part of t...

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...
متن کاملExhaled breath condensate pH assays are not influenced by oral ammonia.
BACKGROUND Measurement of pH in exhaled breath condensate (EBC) is robust and simple. Acidic source fluid (airway lining fluid) traps bases while volatilising acids, leading to EBC acidification in many lung diseases. Lower airway ammonia is one determinant of airway lining fluid pH, raising the concern that addition of the base ammonia by contamination from the mouth might confound EBC pH assa...
