Abstract
C型肝炎病毒為黃熱病毒科(Flaviviridae)之單股正性RNA病毒,由Qui-Lim Choo和George Kuo等學者於1989年以分子生物技術,在非A非B型肝炎之病患血清中鑑別出病毒體,而人類為其主要宿主。依據台灣疾病管制署公布資訊,估計台灣人口約有2%罹患C型肝炎,且南台灣之某些地區的地方性流行率很高。近年來,台灣地區受到C型肝炎病毒感染之人口數及比例正逐年上升;Castillo等學者於2004年發表一項名為潛隱性C型肝炎感染的慢性肝炎,該類型感染的特性是血清中偵測不到HCV RNA卻伴隨有肝功能檢測異常,但約70%罹患潛隱性C型肝炎感染的病人在周邊血液單核球細胞中發現有C型肝炎病毒核酸存在,但尚不了解病毒是否會在這些細胞中進行複製。因而設計此研究,針對肝功能檢測異常捐血人進行篩檢是否有潛隱性C型肝炎病毒感染(Occult Hepatitis C infection;OCI)存在,並統計2004至2013年捐血人C型肝炎感染盛行率。目前台北捐血中心之血液檢測,均以血清/血漿作為檢體來源;在本實驗設計中,將使用不同於捐血中心目前使用之血液檢體,改以周邊血液單核球細胞(Peripheral blood mononuclear cells;PBMCs)取代血清作為實驗檢體進行C型肝炎病毒核酸檢測。由於C型肝炎病毒主要感染肝臟細胞,因此罹患C型肝炎時,丙胺酸轉胺酶(ALT)數值會呈現不穩定的狀態或在臨床診斷臨界值呈現轉變;因此,對於丙胺酸轉胺酶指數異常之捐血人,探討其臨床意義,除生理性異常外,是否有病理性原因存在,實有其必要。為了避免潛隱性C型肝炎病毒感染對血品造成危害,確保血液品質以提升輸血安全,故以此作為本論文之研究主題。
