2. 1. Towards Improved Diagnostics and Monitoring in Childhood Asthma : Methodological and Clinical Aspects of Exhaled NO and Forced Oscillation Technique

   Author : Charlotte Heijkenskjöld Rentzhog; Malinovschi Andrei; Lennart Nordvall; Kjell Alving; Lauri Lehtimäki; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asthma; children; exhaled NO; forced oscillation technique; airway inflammation; small airways; asthma diagnostics; Pediatrik; Pediatrics; Lungmedicin; Lung Medicine;

   Abstract : Background: Asthma is a heterogeneous disease. Diagnosis relies on symptom evaluation and lung function tests using spirometry. Symptoms can be vague. Spirometry is effort-dependent and does not reliably evaluate small airways. READ MORE

4. 2. Nitric oxide within the concept of united airway disease : Exhaled and nasal nitric oxide in cystic fibrosis, asthma and upper airway inflammatory diseases

   Author : Christina Krantz; Andrei Malinovschi; Kjell Alving; Celeste Porsbjerg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nitric oxide; nasal NO; exhaled NO; asthma; cystic fibrosis; airway inflammation; upper airway inflammatory disorders; united airway disease; IgE sensitisation; Lungmedicin; Lung Medicine; Pediatrik; Pediatrics;

   Abstract : Background: Within the concept of united airway disease, it is postulated that inflammatory disorders in the upper and lower airways are interrelated and influence each other. Fractional exhaled nitric oxide (FeNO) is an established biomarker of type-2 inflammation in the lower airways and is elevated in patients with asthma. READ MORE

5. 3. Exahaled NO and small airway function in asthma and cystic fibrosis

   Author : Christina Keen; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asthma; exhaled NO; children; cystic fibrosis; flow independent exhaled nitric oxide; multiple breath inert gas washout; polyunsaturated fatty acids;

   Abstract : Background: Asthma and cystic fibrosis (CF) are chronic inflammatory airway disorders known to involve the peripheral airways. Non-invasive tests sensitive to peripheral airway function and inflammation are therefore of high priority. READ MORE

6. 4. Nitric Oxide Exchange in Central and Peripheral Airways : Determinants in Health and Respiratory Disease

   Author : Andrei Malinovschi; Christer Janson; Kjell Alving; Lena Holm; Elisabeth Bel; Uppsala universitet; []
   Keywords : exhaled nitric oxide; alveolar NO; bronchial NO flux; extended NO analysis; asthma; smoking; snus; IgE-sensitization; pharyngo-oral tract; nitrate; nitrite; pulmonary hypertension;

   Abstract : Background: Exhaled nitric oxide (NO) is a marker of eosinophilic steroid-sensitive inflammation in the airways of patients with respiratory disease. Moreover, information about the localization of inflammation in the respiratory tree is obtained by estimates of bronchial and alveolar contributions to exhaled NO. READ MORE

7. 5. Exhaled markers of oxidative stress in the airways

   Author : Mona Lärstad; Göteborgs universitet; []
   Keywords : exhaled air; exhaled breath condensate; malondialdehyde; 3-nitrotyrosine; ethane; pentane; isoprene; oxidative stress; airways; inflammation;

   Abstract : Breath contains a number of different molecules, some of which may have potential use as markers for oxidative stress in the airways during chronic airway inflammation. The major objectives were to develop and validate methods for quantifying five potential exhaled markers of oxidative stress: malondialdehyde (MDA) and free 3-nitrotyrosine (3-NT) in exhaled breath condensate (EBC) and ethane, pentane and isoprene in exhaled air, and to test the applicability of the methods.
