Acupuncture plus sphenopalatine ganglion needling shows higher response rate than loratadine for allergic rhinitis
In a multicenter randomized controlled trial, 260 patients with persistent moderate-to-severe allergic rhinitis were assigned to one of four 8-week treatments: combination therapy (acupuncture 3 sessions/week plus sphenopalatine ganglion needling 1 session/week), pharmacotherapy (loratadine 10 mg/day), acupuncture alone (3 sessions/week), or sphenopalatine ganglion needling alone (1 session/week). The primary outcome was response rate, defined as ≥30% reduction in total nasal symptom score at Week 8.
At Week 8, the response rate was 82.5% for combination therapy, 71.4% for acupuncture alone, 55.7% for sphenopalatine ganglion needling alone, and 45.3% for pharmacotherapy. The relative risk for combination therapy versus pharmacotherapy was 1.90 (95% CI 1.40-2.58, p<0.001), and for acupuncture alone versus pharmacotherapy was 1.61 (95% CI 1.18-2.21, p=0.003). The difference between sphenopalatine ganglion needling alone and pharmacotherapy was not statistically significant. Combination therapy showed the earliest significant improvement, with a 63.5% response rate by Week 2 (p<0.001). Response rates appeared sustained at a 4-week follow-up.
No safety, adverse event, or tolerability data were reported. Key study limitations, funding sources, and conflicts of interest were also not reported. While the results from this RCT suggest combination acupuncture therapy may offer a non-pharmacologic alternative for symptom management, the absence of safety data and unreported limitations necessitate cautious interpretation. Further research with comprehensive safety reporting is needed to confirm these findings.
