What risk is associated with prolonged use of inhaled corticosteroids in asthmatic patients?

Prolonged use of inhaled corticosteroids in asthmatic patients is associated with an increased risk of infections due to the immunosuppressive effects of these medications. Corticosteroids, while effective in reducing inflammation and controlling asthma symptoms, can impair the body's immune response over time. This makes individuals more susceptible to respiratory infections, such as pneumonia or bronchitis, particularly because the corticosteroids can dampen the action of immune cells that typically fight off infections.

The other options, while they may have specific relevance in different contexts, do not represent the primary risk associated with long-term inhaled corticosteroid use for asthma management. For instance, calcification of bones typically relates more to systemic corticosteroids than to the inhaled forms. Reduced effectiveness of albuterol is not a widely recognized consequence of inhaled corticosteroid use, and thyroid dysfunction is not commonly linked to inhaled corticosteroid therapy either. Therefore, the increased risk of infections is well recognized and supported by clinical observations in patients undergoing chronic treatment with inhaled corticosteroids.
