Abstract
慢性鼻竇炎為一在全球非常普遍的疾病,主要為相關鼻竇區域的慢性發炎反應,然其詳細的病因及發生機轉仍不清楚。顯微鏡下有時可見以嗜酸性球為主的鼻竇黏膜發炎細胞浸潤,先前研究指出慢性鼻竇炎的病因可能與微生物感染、過敏原刺激及宿主本身的免疫反應有關。趨化激素eotaxin及RANTES已證實可吸引嗜酸性球至發炎部位,而介白質IL-21主要表現在人類活化的CD4+ T細胞上,有調控免疫細胞反應及過敏相關抗體IgE的功能。本實驗即試圖了解RANTES, eotaxin及IL-21在慢性鼻竇炎併鼻息肉病人血液中的表現情形其與疾病嚴重度的相關性,以鼻竇電腦斷層評估Lund-McKay法,鼻竇內視鏡鼻瘜肉嚴重程度指標Lund-Kennedy法,及評估慢性鼻竇炎之鼻竇骨壁之發炎程度Global Osteitis Scoring Scale (GOSS)做為臨床嚴中度評估。此外,我們也分離出正常人及慢性鼻竇炎病人之周邊血液單核細胞 (PBMC),以免疫刺激因子處理,取培養液及分離細胞分析其IL-21蛋白質及RNA之表現量。首先分析血清中IgE的含量及上述細胞激素的表現,並藉由鼻竇電腦斷層結果、鼻內視鏡及鼻竇骨壁發炎的評分量表去測量疾病的嚴重性,及其與相關細胞激素變化的關係。結果顯示eotaxin, RANTES及IL-21的濃度均較對照組為高,呈現有意義的差異(p<0.05)。臨床嚴重度則與上述細胞激素之濃度變化均呈正關,但eotaxin的相關性較強。另經免疫刺激因子作用後,慢性鼻竇炎病人之周邊血液單核細胞培養液之IL-21之濃度較正常人高,但IL-21 mRNA之表現則無明顯差異。IL-21, eotaxin, RANTES等細胞激素或趨化激素在慢性鼻竇炎之致病機轉仍有待釐清,然其與該疾病嚴重度之相關性或可作為以藥物或手術治療的預後指標,並對難治極易復發之慢性鼻竇炎病人可發展出新的篩選方式,追蹤方法及治療模式。
