Overview
Dyspnea in asthma, is mainly due to airway obstruction but can be caused by several alternative diagnoses. The impact of sarcopenia on dyspnea in patients with asthma is unknown. Sarcopenic asthma had a reduced physical activity and is associated with airway obstruction compared to non-sarcopenic asthma. In patients with obstructive pulmonary disease, sarcopenia is associated with shallow breathing and diverse sensory and affective components of exertional dyspnea . The morbidity of sarcopenia is also increased by systemic inflammation and the production of inflammatory cytokines as found in inflammatory airway obstruction. The investigators will investigate the prevalence and impact of sarcopenia in asthmatics patients. This will enable to better manage sarcopenia in asthmatic patients, understand its origins and personalize treatment.
Interventions
- Diagnostic test muscle evaluation
The investigators will evaluate the muscle mass and muscle strenght for all patients included - Biological Dosage
Evaluation of the cinetic of biomarkers during exercise - Diagnostic test Cardiopulmonary exercise test
CPET - Combination product Questionnaire and Physical Exam
Evaluating dyspnea, anxiety, sleep, physical activity, quality of life
Primary outcome measures
- Variation in the intensity of dyspnea during exercise mesured with Borg scale (0-10) according to the presence of sarcopenia [Time frame: From baseline (at rest) to the end of the exercise]
Secondary outcome measures (4)
- Variation in exercise-induced release of biomarkers according to the presence of sarcopenia [Time frame: at rest = baseline / right after the end of exercice / 45 minutes after the end of exercice]
- Difference in muscle mass (kg) on impedancemetry according to the presence of sarcopenia [Time frame: Baseline]
- Difference on maximum aerobic capacity (VO2 max in L/mn) , according to the presence of sarcopenia [Time frame: immediately after the exercise test]
- Difference in fat mass (kg) on impedancemetry according to the presence of sarcopenia [Time frame: At baseline]
