Are spirometric values in elderly asthmatic patients influenced by obesity?
The spirometric values decreased significantly in proportion to the increase of BMI and age in patients with asthma, especially among young adults. There was no negative correlation between BMI and FEV(1)  in the group ≥ 60 years of age, suggesting that perhaps the time of disease is a major factor in the loss of lung function than weight gain in the elderly.
Vessel-associated TGF-β1 activity is increased in the bronchial Rbm in smokers and especially those with COPD.
