Airway function indicators and blood indicators in children with dust mite allergic rhinitis after sublingual immunotherapy

摘要

Objective:To evaluate the airway function indicators and blood indicators in children with dust mite allergic rhinitis after sublingual immunotherapy.Methods:A total of 68 children with dust mite allergic rhinitis treated in our hospital from November, 2012 to October, 2015 were selected as the research subjects and randomly divided into observation group 34 cases and control group 34 cases. The control group received clinical routine therapy for allergic rhinitis, the observation group received sublingual immunotherapy, and then differences in basic lung function indicator values, small airway function indicator values and levels of serum inflammatory factors as well as serum ECP, TARC, Eotaxin-2 and VCAM were compared between two groups after treatment.Results:The FVC, FEV1, PEF and FEV1/FVC values of the observation group after treatment were higher than those of the control group (P<0.05); the MMEF, MEF50% and MEF25% values of the observation group were higher than those of the control group, and the proportion of AHR was lower than that of the control group (P<0.05); the serum IL-4, IL-9, IL-12, IL-13 and IL-16 levels of the observation group after treatment were lower than those of the control group, and the IL-10 and IL-12 levels are higher than those of the control group (P<0.05); the serum ECP, TARC, Eotaxin-2 and VCAM levels of the observation group children after treatment were lower than those of the control group (P<0.05). Conclusions:Sublingual immunotherapy for children with dust mite allergic rhinitis can optimize the airway function, reduce the systemic inflammatory response and eventually improve the children’s overall state, and it’s has positive clinical significance.
