[Clinical efficacy and safety evaluation of acupuncture combined with moxibustion in treatment of allergic rhinitis].

OBJECTIVE

To evaluate the clinical efficacy and safety of acupuncture combined with moxibustion on allergic rhinitis.

METHODS

Using the random number table, 80 patients with allergic rhinitis were divided into a medication group and an acupuncture combined with moxibustion (acu-mox) group, 40 cases in each one. In the medication group, ioratadine tables were prescribed for oral administration, one tablet daily for 10 days as 1 session , 3 sessions of treatment were required. In the acupuncture combined with moxibustion group, bilateral Yingxiang (LI20), Yintang (EX-HN3), bilateral Hegu (LI4) and bilateral Shenshu (BL23) were selected as the main points and stimulated with acupuncture and moxibustion; and the acupoint prescription was modified according to symptoms. This combined treatment was given once every day, stimulating for 30 min each time, and 10 treatments made 1 course, for 3 courses of treatment totally. Before and after treatment, the scores for symptoms and physical signs, as well as the score of rhino-conjunctivitis related quality of life scale (R-QOL) were evaluated separately. The sample of the inferior turbinate mucosa tissue was collected and the distribution of eosinophil (EOS) was scored using HE staining and Sheldeny evaluation. Using enzyme-linked immunosorbent assay (ELISA), the contents of serum immunoglobulin E (IgE), retinoic-acid-receptor-related orphan nuclear receptor γt (RORγt), forkhead box protein P3 (Foxp3), interleukin-17 (IL-17), IL-27 and IL-33 were determined. The clinical efficacy was evaluated in the patients with allergic rhinitis of two groups and all the adverse reactions were recorded during treatment.

RESULTS

The scores of symptoms and physical signs as well as the score of R-QOL, and EOS distribution score and the contents of serum IgE, RORγt, IL-17 and IL-33 were all reduced as compared with those before treatment in each group (<0.05), and the contents of serum Foxp3 and IL-27 were increased as compared with those before treatment in each group (<0.05). After treatment, the scores of symptoms and physical signs as well as the score of R-QOL, and the contents of serum IgE, RORγt and IL-33 in the acu-mox group were lower than those in the medication group (<0.05), and the contents of serum Foxp3 and IL-27 were higher than those of the medication group (<0.05). The total effective rate of the acu-mox group was 100.0% (40/40), significantly higher than 82.5% (33/40) in the medication group (<0.05). No ob-vious adverse reaction was found in either group during and after treatment.

CONCLUSION

Acupuncture combined with moxibustion is significantly effective and safe in treatment of allergic rhinitis. Its effect mechanism may be related to the balance modulation of Th1/Th2 and Th17/Treg cells mediated by naive CD4T cells.
