Prove-it Sepsis

H1N1新流感,讓我們見識到科技對抗疾病犀利的一面,快速篩檢30min,PCR 6 小時,那時沒有想到,怎麼這樣的技術,也可以運用到細菌感染的偵測。因為這次H1N1新流感主要是攻擊呼吸系統,併發肺炎感染是主要的表現,在治療方面,是否涵蓋細菌感染的課題就浮上檯面,目前實務上,還是使用十幾年前的作法,也就是Emperical antibiotics coverage- 經驗性抗生素用藥法,這樣的原始方式有其無奈的地方,一,所有的表徵,含影像學如胸x-ray,無法作微生物學的鑑別診斷,二,臨床醫師無法負荷需等到確定的實驗室檢驗結果才投藥。而這樣的結果,額外付出了抗生素濫用的代價,也應運產生感染這一個專門的學科。




今年選出十大影響生活科技的工具發明裡,赫然有一個與PCR技術有關的產品,那就是Abbott 公司出品的PLEX-ID.運用在病毒,法律鑑定,與其他方面,含CDC用來鑑識H1N1新流感。



這期的Lancet,發表一項細菌學檢識產品的觀測報告,相較於傳統方式,快了18小時,敏感性為95%,專一性可達98%,更好的是,對MRSA敏感性與專一性都是100%,這絕對是殺手級的產品,對醫界來說,可以說是一個石破天驚的消息,如果產品可以順利迅速導入市場,抗生素濫用將成為歷史,敗血症休克可以減少,死亡率可望大幅降低。
