There were no significant differences between epistaxis patients who suffered from allergy regarding IL-17A (P=0.969), IL-23 (P=0.777), IFN- (P=0.811), IL-4 (P=0.571), and IL-10 (P=0.238) serum levels, when compared to those without allergy (Figure 6). This evidence concerns the gene IL10 and epistaxis.
