Clinical Efficacy of Wenfei Jianpi Decoction on Moderate to Severe Persistent Allergic Rhinitis with Lung Qi Deficiency and Cold Syndrome / 中国实验方剂学杂志

ABSTRACT

Objective:To observe the efficacy of Wenfei Jianpi decoction on moderate to severe persistent allergic rhinitis (AR) with Lung Qi deficiency and cold syndrome and its effect on substance P (SP) in nasal secretions and peripheral blood proinflammatory factors. Method:One hundred and sixty-six patients were randomly divided into control group and observation group by random number table. Patients in control group got budesonide nasal spray, 2 times/days, and cetirizine hydrochloride tablets, 10 mg/days. And patients in observation group got Wenfei Jianpi decoction for oral, 1 dose/day. A course of treatment was 8 weeks. Before and after treatment, nasal obstruction, itching, sneezing, runny nose, itchy eyes, tears and nasal sign were scored, nasal airway resistance was detected, and rhinoconjunctivits quality of life questionnaire (RQLQ) were scored. Before and after treatment, levels of SP immunoglobulin E (IgE) in peripheral blood, interleukin-4 (IL-4), interleukin-5 (IL-5), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were detected, and eosinophil (EOS) were calculated. Result:By rank sum test, the clinical efficacy in observation group was better than that in control group (Z=2.073, P<0.05). Before and after treatment, scores of total score of nasal symptoms, ocular symptoms and subjective symptoms and nasal sign score were all lower than those in control group (P<0.05). Except sleep and emotion, scores of other dimensions and the total scores of RQLQ were all lower than those in control group (P<0.05). EOS in observation group was less than that in control group (P<0.05). And nasal resistance declined in observation group (P<0.05), and levels of IgE, SP, IL-4, IL-5, IL-6, TNF-α and nasal resistance were lower than those in control group (P<0.05, P<0.01). Conclusion:Wenfei Jianpi decoction can be used to treat moderate to severe persistent allergic rhinitis by relieving subjective symptoms and signs, improving quality of life, inhibiting inflammatory factors and reducing allergic reaction.
