Patients on hemodialysis have a higher prevalence of hepatitis C (HCV) infection compared with the general population. Several factors have been associated with an increased risk of HCV infection in hemodialysis patients, including number of blood transfusions, duration of hemodialysis, previous transplantation, intravenous drug abuse, male gender, and in-center hemodialysis. In addition, there is mounting evidence to suggest nosocomial transmission within hemodialysis units. Although the precise modes of transmission have not been identified, breakdown in standard infection control practices, physical proximity to an infected patient, and sharing of dialysis machines are possible causes. Nonetheless, at the present time, the Centers for disease Control and Prevention (CDC) does not recommend dedicated machines, patient isolation, or a ban on re-use in hemodialysis patients with HCV infection. Consequently, strict adherence to universal precautions and careful attention to hygiene are recommended to reduce the transmission of HCV in dialysis units.
与普通人群相比,接受血液透析的患者丙型肝炎(HCV)感染率更高。血液透析患者HCV感染风险增加与多种因素有关,包括输血次数、血液透析时间、既往移植史、静脉药物滥用、男性性别以及中心内血液透析。此外,越来越多的证据表明血液透析单元内存在医院感染传播。虽然尚未确定确切的传播方式,但标准感染控制措施的失误、与感染患者的密切接触以及透析机的共用都可能是原因。尽管如此,目前疾病控制与预防中心(CDC)不建议为感染HCV的血液透析患者配备专用机器、隔离患者或禁止复用。因此,建议严格遵守通用预防措施并密切注意卫生,以减少透析单元内HCV的传播。
