辛夷散對過敏性鼻炎治療臨床療效評估

過敏性鼻炎是環境中的過敏原對鼻黏膜所誘發的第一型的過敏反應發炎反應,典型症狀包括打噴嚏,鼻癢,流鼻水和鼻塞之單項或多項(1),其盛行率在台灣約為20%,並有逐年增加的趨勢。目前過敏性鼻炎的治療方式是以藥物治療為主,雖然現有的西藥療效不錯,但是大多數患者的症狀仍然反覆發作,無法長期免於鼻炎的困擾。由於我們先前的臨床研究發現中藥混合複方,辛夷散加香砂六君子湯及小青龍湯,對過敏性鼻炎的治療有不錯的療效,而其中辛夷散為主成方,因此我們希望進一步以中醫傳統的古方「辛夷散」,從人體分子免疫學的角度對中藥治療過敏性鼻炎的免疫調節作用方式進行深入的探討,以及臨療效狀評估,及利用鼻聲波反射檢測提供客觀的數據來評估中藥緩解鼻炎的療效。本計劃將選擇臨床症狀及病史皆符合典型過敏性鼻炎特徵,並且接受綜合過敏原篩檢(Phadiatop)對塵螨呈陽性者99例,隨機分為治療組66人及對照組33人。治療組予以中藥複方辛夷散治療,以安慰劑做為對照組,治療期間為三個月。治療前所有患者均接受單一過敏原檢測(CAP),並於治療前後分別評估兩組患者的:一、臨床症狀指數;二、血中過敏抗体IgE的總量;三、血中塵螨特異性抗體IgE的濃度;四、T淋巴球中CD4/CD8比值及IL-4、IL-5、IL-10、IL-13、IFN-γ的濃度;五、多形性白血球IL-8、PGE2、LTC4、sICAM-1、COX2的mRNA表現及嗜中性白血球的吞噬能力;六、鼻腔內的截面積。經由測定不同的細胞激素、細胞黏粘因子、發炎介質等的濃度變化,可以使我們對中藥對人體免疫作用機轉的調節有更進一步的認識;利用鼻聲波反射檢測鼻腔內截面積的改變,更可以客觀地評估中藥緩解鼻塞的療效。這種研究模式的建立,不但有助於日後對過敏性鼻炎的臨床治療及研究,另外也建立中藥在免疫疾病的研究一個新的途徑,如此將有助於加速過敏性疾病的整体中醫藥研究及臨床上的效益。

Study the effects of Shin-Yi-San on the treatment of allergic rhinitis

Allergic rhinitis is the type I hypersensitivity reaction of nasal mucosa to environmental allergen. It is characterized by one or more
symptoms including sneezing, itching , rhinorrhea and nasal congestion.The prevalence of allergic rhinitis in Taiwan is approximately 20% and
increases annually. Controlling the symptoms with medical therapy is the main treatment of allergic rhinitis. Nevertheless, the majority of patient
still suffer from symptom relapse, even in the course of maintained therapy. In the past years, we found the patients with allergic rhinitis
response well to Chinese medicine. The combined regimen of Hsian-Sa-Lieu-Gin-Tze-Tan, Hsiao-Chin-Long-Tang and Shin-Yi-San therapy
has been proven to modulate the cytokine profile of allergic rhinitis in our previous study. We would like to further investigate the modulating
effect of the traditional Chinese decoction Shin-Yi-San to the cytokine profile of allergic rhinitis and its effect to nasal congestion
