[Moderate and severe persistent allergic rhinitis treated with acupoint application therapy of the different intensity: a randomized controlled trial].

OBJECTIVE

To evaluate the clinical therapeutic effects and safety on moderate and severe persistent allergic rhinitis treated with acupoint application therapy of the different intensity during the dog days.

METHODS

One hundred and sixty patients of moderate and severe persistent allergic rhinitis were randomized into a No.1 treatment group, a No.2 treatment group, a No.3 treatment group and a placebo group, 40 cases in each one. The same acupoints were used in the four groups, named Dazhui (GV 14), Dingchuan (EX-B1), Feishu (BL 13), Pishu (BL 20), Mingmen (GV 4), Gaohuang (BL 43), Shenshu (BL 23) and Qihai (CV 6). In the three treatment groups, the fine powder of the ingredients (semen brassicae, radix angeliceae, asarum sieboldii, rhizome corydalis) of compound baijiezi formula was used. In the No.1 treatment group, the herbal paste (ginger-prepared paste) was prepared with ginger juice and the above herbal powder. In the No.2 and No.3 treatment groups, the herbal paste (honey-prepared paste) was prepared with honey with the above herbal powder. In the placebo group, the pseudo-herbal paste of the same appearance was prepared with millet powder and distilled water. The acupoint application was given for 2 h in the No.1 and No.2 groups and was for 6 h in the No.3 treatment group and the placebo group. The acupoint application therapy was given once every week during the dogdays, continuously for 5 weeks. The total nasal symptom score (TNSS), the score of the rhinoconjunctivitis quality of life questionnaire (RQLQ) and the count of blood eosinophils (EOS) were observed in the patients of the 4 groups before and after treatment. The clinical therapeutic effects were compared among the 4 groups. The incidences of the skin adverse reactions were observed in each treatment group.

RESULTS

After treatment, the scores of TNSS and RQLQ were all reduced as compared with those before treatment in the three treatment groups (P<0.05, P<0.01), in which, the improvements in the No.3 treatment group were better than those in the No.1 treatment group and the No.2 treatment group (both P<0.05). After treatment, the count of EOS was all reduced as compared with that before treatment in the three treatment groups (all P<0.05). The differences were not significant statistically among the three treatment groups (all P>0.05). The total effective rate was 85.0% (34/40) in the No.3 treatment group, better than 76.3% (29/38) in the No.1 treatment group, 71.8% (28/39) in the No.2 treatment group and 5.0% (2/40) in the placebo group (P<0.05, P<0.01). The incidences of the skin adverse reaction in the No.3 treatment group and the No.2 treatment group were lower than those in the No.1 treatment group (both P<0.01).

CONCLUSIONS

The acupoint application of the different intensity relieves the symptoms and improves the living quality in the patients of moderate and severe persistent allergic rhinitis. The stimulation of the ginger-prepared herbal paste is strong and induces skin blisters after 2 h herbal application. The stimulation of the honey-prepared herbal paste is moderate and does not induce blisters. The 6 h stimulation of the honey-prepared herbal paste is mild and the therapeutic effect is optimal.
