Abstract Background Respiratory syncytial virus RSV infection is the major cause of bronchiolitis in infants and is a risk factor for the development of asthma. Allergic asthmatics are more susceptible to RSV infection and viral exacerbation. Methods Since the effectiveness of corticosteroids in treating RSV infection has been controversial we tested fluticasone propionate FP and salmeterol Sal alone versus FP plus Sal FPS on RSV-induced airway inflammation. Mice were sensitized and challenged with ovalbumin OVA and infected with RSV. Following infection they were treated with FP Sal or FPS intranasally and airway hyperreactivity AHR inflammation and RSV titers were examined. Results
