non-invasive sampling methods of inflammatory biomarkers in asthma and allergic rhinitis

1 So far, tachykinin receptor antagonists have not shown any efficacy in (clinical models of) asthma (this thesis)

2 Measurement of exhaled no should be performed after maximal bronchodilatation to obtain consistent results (this thesis).

3 Gene expression profiles can be obtained from rna isolated from sputum cell pellets of asthmatic patients (this thesis).

4 Nasal lavage and nasal brush are more suitable for the evaluation of short-term changes following allergen-induced upper airway

inflammation than for long-term monitoring of allergic rhinitis (this thesis).

5 Cleaved slpi reflects mast cell chymase activity in vivo and hence, may serve as a biomarker of allergic airway inflammation in both the upper and lower airways (this thesis).

6 Multiple biomarkers are needed to fully assess the heterogeneous charac- teristics of asthma or allergic rhinitis (Leung T., Thorax 2005;60(10): 822-6) 7 Hypertonic-saline induced sputum proves that amongst the currently

available non-invasive sampling methods ‘what comes hardest, is often most valuable’.

8 Nasal no will probably not develop into a similarly useful biomarker of upper airway inflammation as exhaled no for lower airway inflammation 9 A clinically relevant pharmacokinetic interaction between mk-0873

(a selective pde-4 inhibitor) and oral theophylline is negligible (Boot JD. Pulm Pharmacol Ther. 2008;21(3):573-7)

10 A healthy volunteer in a clinical trial is someone you haven’t studied carefully enough

11 Considering we cannot prove God doesn’t exist, it’s a safer wager to assume he does exist (adapted from Blaise Pascal (1623-1662)) 12 Biofuels maintain the inefficiency of the current transport system

instead of improving it

13 In the end, mortality is the best biomarker

In conclusion, a single inhaled dose of ave5883 provided a modest protection against nka-induced bronchoconstriction in patients with mild to moderate persistent asthma, whereas

Late asthmatic airway response (lar) to inhaled allergen, defined as a fall in forced expiratory volume in 1 second (fev1) of at least 15% from pre-allergen baseline (11), have

The collected sputum supernatant underwent new and optimized processing methods (dialysis and ultracentrifugation) and was analyzed with more sensi- tive detection
