Dust mite drops by improving immune function in treating allergic rhinitis / 中国免疫学杂志

ABSTRACT

Objective:To analyze the immune function regulation and clinical effect of dust mite drops desensitization treatment on children with allergic rhinitis.Methods:80 patients with allergic rhinitis and adenoid hypertrophy treated in our department from January 2012 to June 2014 were selected and randomly divided into experimental group and control group.Control group was treated with ebastine and levocabastine treatment, the experimental group was treated with sublingual containing Dermatophagoides Farinae Drops on the basis of control group.The level of IL-2,IL-6,house dust mite specific IgE (sIgE),dust mite IgE (T-IgE),house dust mite specific IgG4 ( sIgE in) ,blood addicted eosinophile cells ( EOS) ,and induced sputum EOS level were compared between the two groups before treatment and after 2 years treatment.Results:The level of IL-2 in the two groups was significantly higher than that before treatment,the level of IL-6 was significantly lower than that before treatment ( P<0.05 ) .After treatment, the level of IL-2 in the experimental group was significantly higher than that in the control group, the level of IL-6 was significantly lower than that in the control group( P<0.05 ).After treatment, the level of sIgE, T-IgE, blood EOS and induced sputum EOS in the two groups were significantly lower than before treatment,the level of sIgG4 were significantly higher than those before treatment (P<0.05).After the treatment,the level of sIgE, T-IgE, blood EOS and induced sputum EOS in experimental group were significantly lower than control group,and the level of sIgG4 was significantly higher than that in control group ( P<0.05).After treatment,the asthma symptom scores and nasal symptom scores of the two groups were significantly lower than before treatment (P<0.05),and those index of experimental group after treatment were significantly lower than control group ( P<0.05 ).Conclusion: Combine the basis of conventional therapy plus with Dermatophagoides Farinae Drops in the treatment of allergic rhinitis and adenoid hypertrophy children can effectively regulate the immune function of the patients,has good clinical efficacy.
