Abstract:Objective To investigate the serum level of interleukin-34 (IL-34) in patients with allergic rhinitis(AR) and its relationship with serum IL-4, IL-6 and IL-10 levels in order to elucidate the clinical significance of IL-34 in allergic rhinitis. Methods Totally 100 patients of AR were selected as AR group, and 100 healthy subjects were selected as control group in ENT of Jiangshan People’s Hospital from January 2018 to December 2018. The serum IL-34, IL-4, IL-6, IL-10 levels were determined by enzyme-linked immunosorbent assay (ELISA). Results The levels of serum IL-34, IL-4 and IL-6 in AR group were higher than those in control group (P < 0.05), and the IL-10 level was lower than that in control group (P < 0.05).Compared with patients before treatment, the serum IL-34, IL-4 and IL-6 levels were decreased (P < 0.05), and serum IL-10 levels were increased (P < 0.05) after treatment. The serum IL-34 levels in AR patients were positively correlated with serum IL-4 (r = 0.526)and IL-6(r = 0.573) levels (P < 0.05), and negatively correlated with IL-10 levels(r = -0.558)(P < 0.05). Conclusion Serum IL-34 level is elevated in patients with allergic rhinitis. IL-34 may participate in the pathogenesis of allergic rhinitis by participating in inflammatory reactions, and has certain value in the diagnosis and evaluation of allergic rhinitis.
