[Acupuncture for prevention of moderate to severe seasonal allergic rhinitis: a randomized controlled trial].

OBJECTIVE

To observe the clinical efficacy of acupuncture for prevention of moderate to severe seasonal allergic rhinitis.

METHODS

A total of 105 patients with moderate to severe seasonal allergic rhinitis were randomly divided into an observation group (53 cases, 3 cases dropped off) and a control group (52 cases, 4 cases dropped off). The patients in the observation group were treated with acupuncture at Yintang (GV 24), Yingxiang (LI 20), Hegu (LI 4), Zusanli (ST 36), Fengchi (GB 20), Feishu (BL 13), etc. 4 weeks before the seizure period, once every other day, 3 times a week for 4 weeks. The patients in the control group were not given any intervention before the seizure period. Emergency drugs can be given appropriately during the seizure period in both groups. After seizure period, the seizure rate was recorded in the two groups; before treatment and on week 1, 2, 4, 6 of seizure period after treatment, the rhinoconjunctivitis quality of life questionnaire (RQLQ) score and total nasal symptom score (TNSS) were observed in the two groups; the rescue medication score (RMS) was recorded on week 1-6 of seizure period in the two groups.

RESULTS

The seizure rate of the observation group was 84.0% (42/50), which was lower than 100.0% (48/48) in the control group (<0.05). After treatment, the scores of RQLQ and TNSS at each time point of seizure period were decreased compared with before treatment in the observation group (<0.01), which were lower than the control group (<0.01). The RMS score at each time point of seizure period in the observation group was lower than the control group (<0.05, <0.01).

CONCLUSION

Acupuncture can reduce the incidence of moderate to severe seasonal allergic rhinitis, relieve the symptoms, improve the quality of life and reduce the use of emergency drugs.
