Brief Summary

There is increasing evidence in the literature that COPD should not be considered as a localised pulmonary disorder but as a systemic disease involving pathology in several extra pulmonary tissues. Well characterized systemic features are a chronic low grade systemic inflammation, altered body composition and a skeletal muscle fibre type shift. There are indications that an absolute or relative increase of fat mass puts COPD patients at increased risk for cardiovascular pathology while muscle atrophy is associated with a high prevalence of osteoporosis and with impaired physical function. The origin of systemic inflammation is poorly understood. Both endogenous and exogenous risk factors contribute to systemic inflammation and extra-pulmonary manifestations of COPD. Overall objective of study 3: To compare the pattern and severity of the systemic inflammatory profile in relation to skeletal muscle weakness and cardiovascular risk profile in COPD patients with mild to moderate disease compared to non-susceptible smokers. Specific objectives:

  • 30 healthy subjects who after 20 pack years smoking have no signs of COPD (age 40-75 years)
  • 30 COPD patients with GOLD stage II (age 40-75 years)
