Efficacy, Safety and Underlying Mechanisms of Sphenopalatine Ganglion Acupuncture for Seasonal Allergic Rhinitis
Efficacy, Safety and Underlying Mechanisms of Sphenopalatine Ganglion Acupuncture for Seasonal Allergic Rhinitis: a Randomized, Double-blind, Placebo Controlled Study
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 pollen-induced seasonal AR patients and to explore the potential underlying mechanisms.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: SPA acupuncture
active SPG acupuncture plus rescue medication (AA group)
|
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) within first two weeks, and then followed-up for a further 2 weeks (visit 5 and visit 6 ). |
Sham Comparator: sham acupuncture
sham-SPG acupuncture plus rescue medication (SA group)
|
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) with first two weeks, and then followed-up for a further 2 weeks (visit 5 and visit 6). |
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from baseline symptom scores at visit 4
Time Frame: Symptom scores will be assessed at baseline (V0), visit 4( V4). V4 is within 15 minutes after the fourth acupuncture.
|
Patients recorded nasal and ocular symptom severity during the trial.
Four nasal symptoms (itching, sneezing, rhinorrhoea and nasal obstruction) and two ocular symptoms (ocular itch and watery eyes) were individually graded on a ten-point scale (0, no symptoms; 1-3, mild symptoms; 4-7, moderate symptoms; 8-10, severe symptoms).
Our primary outcome is TNSS change from baseline at the end of four-acupuncture treatment at Visit 4 (15 minutes after the fourth acupuncture ).
The investigator will compare the symptom scores between the active acupuncture group and the sham acupuncture group.
|
Symptom scores will be assessed at baseline (V0), visit 4( V4). V4 is within 15 minutes after the fourth acupuncture.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Rescue medication score
Time Frame: RMS will be assessed at baseline (V0), and each visit. V1 to V4 is within two weeks. V5 is one week after the fourth acupuncture, and V6 is two weeks after the fourth acupuncture. There is no acupuncture during both V5 and V6
|
when the symptoms were very severe and could not tolerated, the patients could use loratadine as rescue medication.
The need for rescue medication was assessed as rescue medication score (RMS), analyzed as the weekly sum of daily use of Loratadine (10mg/d, equivalent to 1 point) or nasal corticosteroid spray (2 points)
|
RMS will be assessed at baseline (V0), and each visit. V1 to V4 is within two weeks. V5 is one week after the fourth acupuncture, and V6 is two weeks after the fourth acupuncture. There is no acupuncture during both V5 and V6
|
SNOT-22
Time Frame: SNOT-22 will be assessed at baseline (V0), and each visit. V1 to V4 is within two weeks. V5 is one week after the fourth acupuncture, and V6 is two weeks later. There is no acupuncture during both V5 and V6.
|
SNOT-22 is assessed to evaluate the quality of life of the SAR patients.
|
SNOT-22 will be assessed at baseline (V0), and each visit. V1 to V4 is within two weeks. V5 is one week after the fourth acupuncture, and V6 is two weeks later. There is no acupuncture during both V5 and V6.
|
nasal patency
Time Frame: NCV, NAR and MCA will be assessed at baseline (V0), and each visit. V1 to V4 is within two weeks. V5 is one week after the fourth acupuncture, and V6 is two weeks after the fourth acupuncture.
|
Eccovision acoustic rhinometry (Hood Labs, Pembroke, USA) was used to measure the total nasal cavity volume (NCV) and minimum cross-sectional area (MCA).
