Differences in Initial Immunoprofiles between Recurrent and Nonrecurrent Chronic Rhinosinusitis with Nasal Polyps

Abstract

Nonrecurrent and recurrent CRSwNPs needing revision surgery have different types of inflammatory patterns. Nonrecurrent CRSwNPs exhibits a mixed pattern of T helper (Th) cytokines with significant higher levels of IFN-gamma and lower concentrations of IgE, ECP, and IL-5 as compared with recurrent CRSwNPs that had a predominant Th2 type of inflammation.
