Is Trabecular Bone Score a More Sensitive Marker for Osteoporosis in Asthmatics?

Asthma is a chronic inflammatory disorder of the airway and requires long-term treatment with inhaled corticosteroids (ICS) and oral corticosteroids (OCS) as controller and/or rescue medications. The cumulative lifetime corticosteroid exposure may be very high due to the chronicity of asthma. In particular, severe asthma, which accounts for 5%–10% of asthma, is difficult to control and requires high doses of ICS therapy and intermittent OCS therapy. Therefore, patients with severe asthma are at greater risk of the adverse effects of corticosteroids.
