The dynamic change of cytokines associated with the speccificimmunotherapy and its clinical significance

: Objective:This project aimed to study the dynamic change of the cytokines associated with specific immunotherapy(SIT) pre- and post-SIT.Searching for immune regulatory indicators would used in SIT.Method:One hundred cases who had accepted SIT were enrolled in the project.Data of serum specific IgE and cytokines were statistically analyzed.In the three periods,pre-SIT,17 weeks post-SIT,57 weeks post-SIT,the levels of the eight kinds of cytokines(IL-4,IL-5,IL-8,IL-10,IL-13,IL-17,IFN-γ and TNF-α)were detected,and the dynamic change of the nasal symptoms score were analyzed.Result:The six kinds of cytokines(IL-5,IL-8,IL-10,IL-13,IL-17 and TNF-α)had no significant difference before and after SIT.The level of house dust mite sIgE level was positively correlated with serum IL-5 when the SIT pre-treatment and 57weeks (P<0.05).Pre-treatment and in 17 weeks after treatment,serum IL-5,IL-17 content difference and reduce the magnitude of nasal symptom scores were positively correlated (P<0.01).In 17 weeks of treatment and 57 weeks of treatment,difference of serum IL-10,IL-13,TNF-α levelsand the difference of nasal symptom scores were negatively correlated(P<0.01).Pre- treatment and 57 weeks,difference of serum IL-13,IL-17,TNF-α and the difference of nasal symptom scores were positively correlated (P<0.05),serum IL-10 levels of difference between the nose ministry of magnitude lower symptom scores were negatively correlated (P<0.01).Conclusion:The cytokines (IL-4,IL-5,IL-8,IL-10,IL-13,IL-17,IFN-γ and TNF-α) associated with the SIT play an important role in allergy and can objectively reflect the immune status during SIT.
