Abstract:
Objective To evaluate the effectiveness of allergen specific immunotherapy (SIT) in the treatment of allergic rhinitis. Methods A total of 132 patients with seasonal ragweed allergic rhinitis were enrolled in this study. The patients were randomly divided into two groups. SIT group, in which 68 patients were treated with ragweed SIT for six months before July for 3 years. ST (symptomatic therapy) group, in which 64 patients were treated with ST during seasonal symptomatic period. The healthy control group included 40 subjects. The levels of serum total IgE (tIgE), specific IgE (sIgE), ECP, IgG and IL-4, IL-5, IFN-? were measured, and eosinophil numbers were counted. The symptom score, lung-function test and skin prick test were performed before and after the treatment. Results The elevated levels of tIgE, ECP, IL-4, IL-5 in the sera and eosinophil counts in peripheral blood of the patients were significantly reduced, whereas the levels of IgG and IFN-? were increased following SIT. The levels of serum sIgE were not changed in both SIT and ST groups. 30.88% of the patients were clinically cured, the effective rate was 41.18%, the improvement rate was 20.59% after SIT, and only in 7.39% of patients there was no clinical improvement. In 16.18% of patients there were mild side effects to SIT. In the ST group, there was on change in all the laboratory results and clinical symptoms, and 25% of the patients developed asthma. Conclusion SIT was able to improve the symptoms and laboratory results of the patients with allergic rhinitis. The results indicated that SIT may be an effective and safe therapy for patients with allergic rhinitis.
