Abstract
慢性鼻竇炎併鼻息肉主要為源自篩竇、上頷竇及中鼻甲附近區域的發炎反應,然其詳細的病因及發生機轉仍不清楚。顯微鏡下可見以嗜酸性球為主的鼻竇黏膜發炎細胞浸潤,先前研究顯示此一現象受到趨化嗜酸性球的細胞激素表現所調控,故推測鼻息肉的形成可能與微生物感染、過敏原刺激及宿主本身的免疫反應有關。CC趨化激素Eotaxin 及RANTES已證實可吸引嗜酸性球至發炎部位,本實驗即試圖了解這些對嗜酸性球有特異性之趨化激素的蛋白質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及周邊血液嗜酸性球濃度的的相關性,以探討CC趨化激素在慢性鼻竇炎病鼻息肉發病過程中所扮演的角色。20位即將進行鼻竇內視鏡手術的慢性鼻竇炎病人為實驗組,取其血清進行研究,並以鼻竇電腦斷層攝影結果,使用Lund-MacKay法判斷其臨床嚴重度;另取20位正常人之血液樣本為對照組。結果顯示實驗組血液中Eotaxin 及RANTES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Eotaxin 及RANTES濃度均呈正相關,但Eotaxin的相關性較強。另以實驗組血液中Eotaxin 及RANTES與血液嗜酸性球比率加以比較,結果Eotaxin及RANTES均呈現正相關。我們認為對慢性鼻竇炎病人而言,疾病嚴重度主要與Eotaxin之表現有關,暗示其在趨化嗜酸性球由周邊血液至病灶發炎部位,及疾病的病理生理機轉上扮演較重要的角色。
