RESUMEN
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 (P<0.05), and the contents of serum Foxp3 and IL-27 were increased as compared with those before treatment in each group (P<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 (P<0.05), and the contents of serum Foxp3 and IL-27 were higher than those of the medication group (P<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 (P<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 CD4+T cells.
