Association Between Reported Use of Inhaled Triamcinolone and Differential Short-term Responses to Aerosolized Albuterol in Asthmatics in an Emergency Department Setting

Forty-four adult patients with acute asthma were treated with albuterol at a rate of 15 mg/h over 2 h. Analysis of covariance showed a significantly higher baseline adjusted mean for both percent predicted forced expiratory volume in 1 s (PFEV1) (p=0.045) and percent predicted forced vital capacity (PFVC) (p=0.022) at 50 and 110 min for the patients who reported triamcinolone use. Although heart rates decreased overall during the first hour of albuterol treatment, a rise in mean heart rate occurred during the second hour of treatment only in patients reporting triamcinolone use (p=0.005). After accounting for the effects of parenteral corticosteroids, the effect of reported triamcinolone use remained significant. These data suggest that use of inhaled corticosteroids in this context may be associated with enhanced local and systemic β-responsiveness, and if a causal relationship could be confirmed, this may constitute yet another advantage of early inhaled corticosteroid treatment in asthma. These data also suggest that chronotropic effects of high-dose albuterol should be monitored in patients using inhaled triamcinolone.

Key Words: adult • β-agonist • corticosteroid • high dose
