To observe the clinical efficacy of modified painless wheat-grain blistering moxibustion for allergic rhinitis (AR) of lung deficiency and cold attacking, and to explore its effects on serum immunoglobulin E (IgE) and interleukin-10 (IL-10).

Ninety-eight patients of perennial AR with lung deficiency and cold attacking were randomly divided into an observation group (49 cases, 2 dropped out) and a control group (49 cases, 2 dropped out). The control group received mometasone furoate nasal spray treatment. The observation group received modified painless wheat-grain blistering moxibustion at bilateral Feishu (BL 13), Gaohuang (BL 43), Zusanli (ST 36), and Shenzhu (GV 12) in addition to the control group's treatment. Moxibustion at Shenzhu (GV 12) was applied once every other day, 3 grains each time, forming moxibustion sores after about one week. After sores formed, moxibustion was applied once every other 2 days. For Feishu (BL 13), Gaohuang (BL 43), and Zusanli (ST 36), moxibustion was applied on one side first, every other day, 3 grains each time, until sores formed, then on the other side, alternating sides in a cycle. Both groups were treated for 4 weeks. The total nasal symptoms score (TNSS), nasal symptom visual analogue scale (VAS), and rhinoconjunctivitis quality of life questionnaire (RQLQ) scores were observed before and after treatment, and after 4 and 12 weeks of treatment completion (follow-ups). Serum IgE and IL-10 levels were measured before and after treatment, and treatment efficacy and recurrence rates at follow-ups were recorded.

Compared before treatment, TNSS, VAS, and RQLQ scores in both groups were reduced after treatment and at follow-ups (P<0.05), and these scores in the observation group were lower than those in the control group (P<0.05). Except for TNSS scores in the control group at the follow-ups, and in the observation group at the 4-week follow-up, all scores at follow-ups in both groups were higher than those after treatment (P<0.05). Compared before treatment, serum IgE levels in both groups were decreased (P<0.05), and serum IL-10 levels were increased (P<0.05) after treatment. The observation group had lower serum IgE levels and higher IL-10 levels than the control group (P<0.05). The total effective rate in the observation group was 93.6% (44/47), higher than 74.5% (35/47) in the control group (P<0.05). The recurrence rates after 4 and 12 weeks of treatment completion in the observation group were lower than those in the control group (4.5% [2/44] vs 22.9% [8/35], 9.1% [4/44] vs 40.0% [14/35], P<0.05).

On the basis of mometasone furoate nasal spray, modified painless wheat-grain blistering moxibustion could improve clinical symptoms in patients of AR with lung deficiency and cold attacking, and provide more sustained long-term efficacy, possibly through the regulation of serum IgE and IL-10 levels.
