Brief Summary
COPD is ranked number 3 by the WHO list of important diseases worldwide and is the only disease with increasing mortality. The pathogenesis of cigarette smoke-induced COPD is obscure, therefore more insight is needed to design effective anti-inflammatory agents. We hypothesize that healthy individuals who are susceptible to smoking demonstrate a higher and aberrant inflammatory response to cigarette smoke. This susceptibility is caused by heterogeneous factors and is associated with various polymorphic genes that interact with each other and with the environment. Objective:
- To define mediators involved in the early induction of COPD in susceptible smokers (and so to define new drug targets)
- To develop new biological and clinical markers for the early diagnosis and monitoring of COPD
- To compare between susceptible and non-susceptible individuals the corticosteroid responsiveness of bronchial epithelial cells in vitro, and to study the mechanisms of smoking-induced corticosteroid unresponsiveness.
- To study the role of candidate genes that may play a role in the development of fixed airway obstruction, and to identify clues for patient's responsiveness to specific drugs.

Outcome Measures
Primary Outcomes (1)
Local inflammation before and after cigarette smoking assessed by exhaled breath condensate, microprobe sampling and bronchial biopsies.
Secondary Outcomes (3)
Systemic inflammation before and after cigarette smoking assessed by the expression of established and newly developed markers on innate immune cells associated with pre-activation.
Extensive clinical characterisation including life style factors, lung function, CT scanning of the lung.
Distribution of candidate genes (SNPs) for COPD within the study population and associations with the inflammatory responses on acute smoking
Study Arms (5)
1
20 healthy individuals not susceptible for COPD (age 18-40 years, \>0\>10 packyears, FEV1/VC \>70%, FEV1 \>85% predicted)
2
20 healthy individuals susceptible for COPD (age 18-40 years \>20 packyears, FEV1/VC \>70%, FEV1 \>85% predicted) and high prevalence of COPD in smoking family members older than 45 years
3
20 healthy individuals very susceptible for COPD (age 18-40 years, \> 0 \> 10 packyears, FEV1/VC \>70%, FEV1 \>85% predicted), and one of the smoking family members has severe early onset COPD or mild COPD with very low smoke exposure
