Abstract
The effect of aspirin desensitization (AD) on immunologic profile of patients with AERD has been poorly understood. This study is aimed at investigating the effect of AD on clinical and immunological markers of patients with AERD. This randomized double-blind placebo-controlled trial comprised 34 adult patients (67.6% female) with chronic rhinosinusitis, nasal polyps, and aspirin-intolerant asthma. The active group underwent AD over a 2-day period with increasing doses of aspirin (60, 125, 325, and 625mg), followed by receiving aspirin 625mg twice daily for 6months. Symptom scores and medication needs of patients with AERD who have undergone AD were significantly lower compared to the placebo group after 6months (7.5±3.5 vs. 10.6±3.8 and 9.3±2.0 vs. 11.0±3.1, respectively, all p<0.05). However, no significant difference was observed in serum concentration of IL-10, IFN-γ, and TGF-β between two groups neither at baseline nor at the end of study.
