Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In recent years, a number of randomized controlled trials have confirmed the efficacy and safety of acupuncture in the treatment of allergic rhinitis (AR). Indeed, the latest American clinical guidelines recommended acupuncture treatment for AR patients who are interested in non-pharmacological treatment.

In conventional acupuncture treatment for AR, needles are inserted at specific acupoints in the body; with several studies demonstrating acupuncture of sphenopalatine ganglion (SPG) to improve nasal symptoms and quality of life in nasal inflammatory diseases.

The investigators hypothesize that, compared with sham acupuncture and rescue medication (RM), active SPG acupuncture combined with RM would lead to greater improvements in symptoms score and reduction in overall need for antihistamines. To test this hypothesis the investigators design a randomized, double blind, controlled trial to evaluate the efficacy of SPG acupuncture in perennial AR patients (allergic to indoor allergens, including house dust mite, fungi, animal dander and so one) and to explore the potential underlying mechanisms.

SPA acupuncture

active SPG acupuncture plus rescue medication (AA group)

Group Type ACTIVE_COMPARATOR

SPA acupuncture

Intervention Type PROCEDURE

For patients in the AA group, acupuncture was performed at a selected point in the SPG by inserting the needle from the lower border of the zygomatic arch, posterior to the suture protuberance between the zygomatic process and temporal process. The needle was directed obliquely anteriorly, until nearly the whole needle was beneath the skin, and then rotated until the patient felt "de-qi" sensations . The patients in the AA group received four courses of active acupuncture(visit 1,2,3 and 4), twice a week during weeks 1 and 2, and then followed-up for a further 2 weeks (visit 5 during week 3 and visit 6 during week 4).

sham acupuncture

sham-SPG acupuncture plus rescue medication (SA group)

Group Type SHAM_COMPARATOR

sham acupuncture

Intervention Type PROCEDURE

For patients in the SA group, the needle was inserted at the same acupuncture point as for patients in the AA group, but to a depth of only 2-3cm and the procedure of rotating, twirling and thrusting the needle was repeated. During the acupuncture process, the acupuncturist sat on the side of the participant, where the patient could neither see the acupuncturist's face nor the length of the needle. The patients in the SA group received four courses of active acupuncture(visit 1,2,3 and 4), twice a week during weeks 1 and 2, and then followed-up for a further 2 weeks (visit 5 during week 3 and visit 6 during week 4).
