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 کاملExhaled breath condensate pH and exhaled nitric oxide in allergic asthma and in cystic fibrosis.
BACKGROUND It has been proposed that the pH of airway lining fluid may regulate the fractional exhaled concentration of nitric oxide (Fe(NO)) in respiratory disease. METHODS Fe(NO), exhaled breath condensate (EBC) pH, and EBC concentrations of nitrite plus nitrate (NO2/NO3) were compared in 12 subjects with stable asthma, 18 with stable cystic fibrosis (CF), and 15 healthy control subjects. E...
متن کاملIncreased nitrotyrosine in exhaled breath condensate of patients with asthma.
The reaction of nitric oxide (NO) and superoxide anions (O(2)(-)) in the airway results in the formation of peroxynitrite, a highly reactive oxidant species. Peroxynitrite reacts with tyrosine residues in proteins to form the stable product nitrotyrosine. We investigated whether nitrotyrosine in exhaled breath condensates may be increased in patients with asthma. Four groups of nonsmoking subje...
متن کاملSafety and success of exhaled breath condensate collection in asthma.
BACKGROUND Exhaled breath condensate (EBC) is a rapidly expanding area of research to study airway inflammation through the detection of volatile and non-volatile substances in the airways. AIMS To determine the safety and feasibility of EBC procedure in a group of children with asthma of varying severity. METHODS In a cross sectional study of children aged 4-17 years, 18 healthy and 91 ast...
