Objective: To assess the efficacy and the transformation of IFN-gamma, IL-4, total IgE and specific IgE before and after specific immune therapy(SIT) in patients with allergic rhinitis.
Method: The subjective symptom and levels of IFN-gamma, IL-4, total IgE and specific IgE were observed in 40 patients with allergic rhinitis before and after SIT.
Result: Total effective rate in patients after SIT was 85%. There's no significant difference between the levels of specific IgE before and after SIT(P>0.05) ,while the levels of IL-4 and total IgE were significantly lower, the levels of IFN-gamma were significantly higher pre than that of post SIT.
Conclusion: SIT is safe and effective,and can regulate the levels of IFN-gamma, IgE and IL-4. But the role of specific IgE in SIT is still unknown.
