Interleukin ۱۷A: A Potential Target for Its Plausible Roles in the Pathogenesis of Idiopathic Epistaxis

Introduction:It has been reported that inflammation may be a potential risk factor for the progression of epistaxis. Due to the major roles played by Th۱۷ in the induction of inflammation, the present study aimed to assess the serum levels of Interleukin ۱۷A (IL-۱۷A) and IL-۲۳, as the most important cytokines in the Th۱۷ pathway, as well as IFN-g, IL-۴, and IL-۱۰ serum levels, as regulatory cytokines for Th۱۷ cells in patients with idiopathic epistaxis.  Materials and Methods:The serum levels of IL-۴, IL-۱۰, IL-۱۷A, IL-۲۳, and IFN-g were evaluated in ۹۰ patients with idiopathic epistaxis and ۹۰ healthy controls using enzyme-linked immunosorbent assay (ELISA) technique. Results:The obtained results pointed out that the serum levels of IL-۱۷A and IL-۱۰, but not IL-۴ and IL-۲۳, were significantly up-regulated, and IFN-g serum levels were significantly down-regulated in patients with idiopathic epistaxis. Furthermore, female patients with epistaxis had higher IL-۱۰ serum levels. Conclusions:As evidenced by the results of the present study, IL-۱۷A is the main cytokine which participates in the pathogenesis of idiopathic epistaxis; moreover, in association with IL-۱۰, it can be regarded as the suppressor of IFN-g in patients.
