Brief Summary:

Limb muscle dysfunction, characterized by atrophy and weakness, is amongst the most troublesome systemic consequences of chronic obstructive pulmonary disease (COPD) leading to poor functional status and premature mortality.

One prevailing hypothesis stipulates that the deterioration in muscle structure and function during COPD results from a spillover of inflammatory mediators from the lungs to the systemic circulation and then to the muscles.


Condition or disease Intervention/treatment
Chronic Obstructive Pulmonary Disease Other: No specific intervention for this study

Detailed Description:
The investigators objective is to investigate the impact of COPD on key signaling pathways involved in the muscle atrophy. Moderate to severe COPD patients (FEV1 under 60% of predicted) and healthy controls will be recruited. All of the investigators patients will undergo a thorough baseline assessment in pulmonary capacity, muscle force and body composition. Blood sampling and biopsy of the quadriceps will be done. Key proteins of signaling intramuscular pathways involved in protein synthesis and degradation will be measured in the quadriceps.

Primary Outcome Measures :
  1. Decrease of protein degradation in muscles of wasted COPD patients [ Time Frame: At baseline (COPD in a stable state of the disease) ]

Secondary Outcome Measures :
  1. Increase of protein synthesis in muscles of wasted COPD patients [ Time Frame: At baseline (COPD in a stable state of the disease) ]

Biospecimen Retention:   Samples With DNA
Blood sample and muscle biopsy of vastus lateralis (quadriceps)
