What is it about?
Some studies suggest that bronchial asthma may be causally associated with obstructive sleep apnea (OSA), and the two diseases could potentiate each other. This study, in a very large European cohort of patients with suspected OSA, examined the clinical characteristics of asthmatic and non-asthmatic subjects.

Why is it important?
The results suggest that in men sleep apnea does not show major differences between asthmatics and non-asthmatic subjects. Instead asthmatic women are often obese, obesity being a major risk factor for OSA and possibly explaining the high frequency of OSA in asthmatic women.
Perspectives
There is a need for studies assessing the role of OSA associated with other diseases, since this may suggest more effective treatment strategies. The literature on asthma and OSA is still controversial. Our study in over 15,000 subjects with suspected OSA suggests that sleep studies may be especially indicated in obese asthmatic women.
