Abstract:
Objective To evaluate the efficacy and safety of specific immunotherapy (SIT) to allergic rhinitis in children.Methods Sixty-four patients with mite allergy allergic rhinitis in children,were divided into two groups by random digits table:treatment group and control group,each group with 32 cases.Treatment group was given SIT with standardized allergen vaccine for 3 years on the basis of symptomatic therapy,control group only received symptomatic therapy.Observation indexs included rhinitis symptoms score,drug score,skin index (SI),serum specificity IgE (sIgE),peripheral eosinophil (Eos) counting,development of asthma and the new sensitization.Results The Eos counting,SI after treatment 3 years in treatment group were significantly better than those before treatment and those in control group after treatment 3 years[(0.14 ± 0.12) × 109/L vs.(0.74 ± 0.18) × 109/L,(0.78 ± 0.36) × 109/L and 1.03 ± 0.13 vs.1.51 ± 0.32,1.51 ± 0.37] (P ＜ 0.01).There was no statistically significant difference in sIgE between two groups (P ＞0.05).The rhinitis symptoms score,drug score in two groups after treatment 1,2,3 years were significantly better than those before treatment (P ＜ 0.01).The rhinitis symptoms score,drug score in treatment group after treatment 1,2,3 years were significantly better than those in control group(P ＜ 0.01).The rate of new sensitization in treatment group was significantly lower than that in control group [3.1％ (1/32)vs.34.4％ (11/32),P ＜ 0.01].Conclusion Keeping long-term SIT is effective and safe for children's allergic rhinitis induced by mite,it also prevents new allergen appeared and allergic rhinitis development for asthma.
