Effect of subcutaneous immunotherapy with specific dust mites on allergic rhinitis in children MA Haiyan1* WANG Dongming 1 DING Ling 2 GUO Jinxia 1 ZHENG Zhaobing 1 WANG Junxia 1 1 Department of Pediatrics,Huantai People's Hospital,Zibo 256400,Shandong,P.

China 【Abstract】 Objective To investigate the effect of subcutaneous immunotherapy with specific dust mites on allergic rhinitis ( AR) in children and the levels of serum immune factors and Th1 /Th2 cells. Methods The clinical data of 82 children with AR before and after the treatment were retrospectively analyzed,and visual analogue scale ( VAS) score was performed. The changes of serum IgE,IL-2,IL-4 and INF-γ,as well as Th1 /Th2 of immune cells were analyzed by ELISA and flow cytometry respectively. Results VAS scores of AR children decreased gradually before the treatment,after the initial treatment,and 1 year,2 years and 3 years of maintenance treatment. After 2 years of maintenance treatment,the levels of serum IgE and IL-4 decreased significantly,while the levels of INF-γ and IL-2 increased significantly,P < 0. 05. In the 2-year maintenance treatment group,the total blood Th1 cell content increased,while Th2 cell content decreased,both P < 0. 05. Conclusion Subcutaneous immunotherapy with specific dust mites can effectively relieve symptoms of AR in children,improve serum IgE,IL-2,IL-4 and INF-γ levels and restore Th1 /Th2 balance. 【Keywords】 allergic rhinitis; specific dust mite immunotherapy; cytokine; Th1 /Th2 cell; blurred vision scale
