Objective:To study the ventilation function after sublingual dermatophagoides farinae drops combined with loratadine treatment of children with asthma and allergic rhinitis and the influence on serum biochemical indexes.Methods: A total of 40 children with asthma and allergic rhinitis treated in our hospital between September 2013 and March 2015 were collected and divided into the control group (n=22) who accepted loratadine therapy alone and the observation group (n=18) who accepted sublingual dermatophagoides farinae drops combined with loratadine therapy after the treatment was reviewed. Before treatment and after 6 months and 1 year of treatment, spirometer was used to test ventilation function indexes;ELISA method was used to determine the contents of inflammatory mediators;RIA method was used to determine the contents of airway remodeling indicators.Results:Before treatment, differences in ventilation function index levels as well as inflammatory mediator and airway remodeling index contents were not statistically significant between two groups of children. After 6 months and 1 year of treatment, FEV1, FVC and PEF levels of observation group were higher than those of control group;serum IL-2 content was higher than that of control group while IL-5, IL-17 and IL-33 contents were lower than those of control group;serum PDGF-BB, TGF-β1 and NF-κB contents were lower than those of control group.Conclusion:Sublingual dermatophagoides farinae drops combined with loratadine therapy can optimize the ventilation function, reduce the systemic inflammatory response and inhibit airway remodeling in children with asthma and allergic rhinitis.
