Abstract

Background. Allergy to cat dander is a common form of allergic disease. Allergen immunotherapy has been demonstrated to be effective in decreasing allergic symptoms. Objectives. To examine outcomes in allergic asthmatic patients on cat immunotherapy (CIT) compared to allergic asthmatics on traditional immunotherapy (IT) without cat sensitivity. Methods. A retrospective review identified allergic asthmatics on CIT for at least three years. An equal number of allergic asthmatics on IT were identified for comparison. Outcomes investigated include measurements of risk of asthma exacerbation. Results. Thirty-five patients were identified in each group. There were no differences in the CIT group versus the comparison group regarding total number of prednisone tapers (18 tapers versus 14 tapers, resp.), number of patients requiring prednisone tapers (10 patients versus 10 patients, resp.), total number of acute visits (29 visits versus 38 visits, resp.), and number of patients requiring acute visits (15 patients versus 21 patients, resp.). When stratified by concomitant ICS use, patients on CIT were less likely to require an acute visit (46% versus 78%, resp.). Conclusions. Allergic asthmatics with cat sensitivity on CIT with close dander exposure have similar risk of asthma exacerbation compared to allergic asthmatics without cat sensitivity on immunotherapy. © 2013 Aerik A.
