A Rapidlatex Test for the Serological Diagnosis of Helicobacter Pylori

以快速乳膠凝集之血清學試驗診斷幽門曲狀桿茵感染之價值

摘要


幽門曲狀桿菌(Helicobacter Pylori)被認為是B型胃炎及消化性潰瘍疾病的主因之一,感染幽門曲狀桿菌的病人血清中會出現抗體,經由血清抗體的測定,能對幽門曲狀桿菌感染的診斷及流行病學有所了解。本研究乃為評估一種最新發展出來有關於幽門曲狀桿菌抗體的乳膠凝集試驗(Pyloriset latex agglutination test),應用在幽門曲狀桿菌感染的血清學診斷情況。 臺北市立忠孝醫院自民國79年7月至80年2月間對96位具胃腸症狀之病患進行研究,病人包括63位男性,33位女性,平均年齡42歲。每位病患接受胃鏡檢查,並進行胃鏡切片;另外抽血試驗Pylori test測定血清學反應,胃鏡檢查42位為單純胃炎,其餘54位則伴隨有消化性潰瘍。 結果顯示病理切片有幽門曲桿菌感染者佔75位,其中Pyloriset test陽性者有51位:無幽門曲桿菌感染之病理切片有21位,其中Pylorises test陰性者有9位。其 Sensitivity和Specificity分別為68%及43%。因此,Pyloriset latex agglutination test雖然是一便捷,便宜、且不具侵襲性的檢查,但本研究顯示其敏感性與特異性均不足,是否可應用於幽門曲狀桿菌感染病患之篩檢,仍有待評估。

並列摘要


The aim of this study was to evaluate the usefulness of a newly developed latex agglutination test for serodiagnosis of Helicobacter pylori (HP) infection. Gastric antral biopsies from 96 patients were examined histologically and sera were underwent latex test for HP. The ”Pyloriset latex agglutination test” showed 68% sensitivity (51 positive serological cases in 75 positive pathological cases) and 43% specificity (9 negative serological cases in 21 negative pathological cases) for HP in regard to histologic diagnosis. The validity of pyloriset test needs further confirmation. It seems not a reliable method for diagnosis of HP infection at present study.
