OBJECTIVES/HYPOTHESIS: Viral hepatitis C is a worldwide public health problem. Hepatitis C virus is mainly transmitted by parenteral or percutaneous route. Nonparenteral transmission, such as through sexual activity, household contact, and vertical or perinatal exposure to body fluids or secretions, can occur, which has been studied before. Cerumen, however, has not been investigated for its ability to transmit hepatitis C virus. The aim of this study is to evaluate the importance of cerumen in transmission of hepatitis C virus infection.
This study was performed on 35 patients with confirmed chronic hepatitis C virus infection.
Thirty-five cerumen specimens collected from the patients with hepatitis C virus RNA in their sera were prospectively analyzed for the presence of hepatitis C virus RNA by polymerase chain reaction.
None of the 35 cerumen specimens were positive for hepatitis C virus RNA.
This study showed that cerumen has no risk for transmission of hepatitis C virus infection, even in patients with high hepatitis C virus RNA serum levels; however, standard infection control precautions should be applied carefully in all examinations and surgical operations of the ears.
目的/假设:丙型病毒性肝炎是一个全球性的公共卫生问题。丙型肝炎病毒主要通过肠道外或经皮途径传播。非肠道外传播,如通过性活动、家庭接触以及垂直或围产期接触体液或分泌物,此前已有人进行过研究。然而,耵聍传播丙型肝炎病毒的能力尚未得到研究。本研究的目的是评估耵聍在丙型肝炎病毒感染传播中的重要性。
本研究对35例确诊为慢性丙型肝炎病毒感染的患者进行。
前瞻性分析从血清中检测到丙型肝炎病毒RNA的患者身上采集的35份耵聍标本,采用聚合酶链反应检测丙型肝炎病毒RNA的存在情况。
35份耵聍标本中无一例丙型肝炎病毒RNA呈阳性。
本研究表明,即使在血清丙型肝炎病毒RNA水平较高的患者中,耵聍也没有传播丙型肝炎病毒感染的风险;然而,在所有耳部检查和手术中仍应谨慎应用标准感染控制预防措施。
