Rationale Allergen challenge (AC) allows evaluation of anti-inflammatory drug
effect, though few readouts are pathway-specific.
Aim: To evaluate the reproducibility of AC-induced sputum Th2-cytokines and
gene expression and their response to fluticasone (FP).
Methods: Following a placebo run-in, 13 asthmatics participated in a randomized,
placebo (P)-controlled, cross-over study. Subjects randomly inhaled FP (5x500
mcg) or P pre- until 24 h post-allergen. At 24 h pre- and 7 & 24 h post-allergen, spu-
tum was induced, split into 2 parts (A+B): A) ultracentrifuged and Th2-cytokines
were measured by a multiplex platform; B) RNA was isolated from cell pellets,
amplified by NUGEN and profiled on Affymetrix arrays. Effects of FP vs P on
allergen-induced changes in cytokine levels and gene expression were analyzed by
a mixed ANCOVA.
Results: At 7 h post-allergen, sputum IL-13, IL-5 and eotaxin-3 were increased
by 9.76, 5.67 and 2.24-fold, resp. (all p<0.001), with reductions by FP of 89%
(p<0.001), 83% (p<0.001) and 45%, resp. (p=0.01). Fold changes between the
placebo run-in and treatment periods indicated good reproducibility (observed
range 0.7 to 1.6). Allergen also increased sputum gene expressions of IL-13, IL-5
and IL-4 by 7.73, 5.57 and 5.98-fold, resp. (all p<0.001) with reductions by FP of
88%, 91% and 84%, resp. (all p<0.001).

Background: In COPD patients, tachypnea is commonly observed on exertion.
It may further exacerbate exertional dyspnea, but the underlying mechanism is
undetermined yet.
Objectives: This study was conducted to examine airway resistance at varying
respiratory rate and evaluate the effect of short-acting β2 agonist (SABA) on
airway resistance during hyperventilation in COPD patients.
Methods: Airway resistance was measured in 12 COPD patients during baseline
breathing and metronome-paced hyperventilation using impulse oscillometry. The
effects of SABA (100 mcg x 3 puffs of salbutamol or 10 mcg x 2 puffs of pro-
caterol) on airway resistance was assessed in 6 moderate to severe COPD patients
receiving 18 mcg of tiotropium bromide daily.
Results: Resistances of total (R5) and distal airways (R5-R20) significantly in-
creased at respiratory rate (RR) of 20 (p < 0.05), 30 (p < 0.01), and 40/min (p
< 0.005) compared with those at baseline breathing. In particular, significant in-
creases in distal airway resistance were observed during expiration. Only procaterol
significantly reduced hyperventilation-induced increase in airway resistances of
total (R5 at RR40 – R5 at baseline, p < 0.05) and distal airways (R5-R20 at RR40
– R5-R20 at baseline, p < 0.05). Both SABA significantly reduced reactance at 5
Hz at RR40 (p < 0.05).
Conclusions: Elevation in airway resistance of distal airway during expiration was
induced by hyperventilation. This condition may aggravate air-trapping on exertion
in COPD patients. Pretreatment (so-called “assist-use”) with SABA, especially
procaterol, may attenuate airway resistance induced by tachypnea.

Background/Rationale: Roflumilast (ROF) is an oral, selective phosphodiesterase
4 (PDE4) inhibitor developed for anti-inflammatory treatment of COPD. It is
catalysed by cytochrome P450 (CYP) 1A2 and 3A4 to its active metabolite
roflumilast N-oxide (RNO). This analysis evaluated the safety and the potential
