Previous studies have provided conflicting results on the presence of hepatitis C virus-RNA in saliva. In this study, 23 (62%) of 37 patients tested positive for hepatitis C virus-RNA in saliva, using polymerase chain reaction analysis. A slightly greater proportion had a sporadic rather than a parenteral origin of chronic hepatitis C. These results provide a biological basis for saliva as a possible source of hepatitis C virus (HCV) infection, but do not necessarily imply transmission by this route.
先前的研究对于唾液中丙型肝炎病毒核糖核酸(HCV-RNA)的存在给出了相互矛盾的结果。在本研究中,采用聚合酶链反应分析,37例患者中有23例(62%)唾液中丙型肝炎病毒核糖核酸检测呈阳性。慢性丙型肝炎起源于散发性感染而非经肠外感染的患者比例略高。这些结果为唾液作为丙型肝炎病毒(HCV)感染的一个可能来源提供了生物学依据,但并不一定意味着通过该途径传播。
