Abstract: 目的评价聚合酶链反应方法检测诱导排痰标本中卡氏肺孢子虫DNA对卡氏肺孢子虫肺炎(PCP)的诊断意义.方法分别用姬姆萨和六胺银(GMS)两种染色方法和mt-rRNA-PCR方法检测痰液中的卡氏肺孢子虫.结果化学染色法检测16例临床拟诊PCP的患者痰标本,结果8例阳性,20例非PCP患者痰标本均为阴性,化学染色方法的敏感性和特异性分别为50%和100%.PCR方法检测16例临床拟诊PCP患者痰液中卡氏肺孢子虫,14例阳性, 20例非PCP患者痰标本均为阴性,mt-rRNA-PCR方法的敏感性和特异性分别为88%和100%.结论姬姆萨和GMS两种细胞化学染色方法联合检测痰标本卡氏肺孢子虫,特异性高,但敏感性偏低.mt-rRNA-PCR检测痰标本中卡氏肺孢子虫DNA方法敏感性高于化学染色法且特异性高,更适于临床应用.
