生态变化、人口流动和日益城市化促进汉坦病毒的扩散,使人类面临病毒传播和随之而来的疾病的高风险。目前有限的治疗选择使得开发抗病毒策略成为迫切需要。利巴韦林是目前唯一用于治疗由汉滩病毒(HTNV)引起的肾综合征出血热(HFRS)的抗病毒药物,尽管这种药物有严重的副作用。因此,我们研究了一种新的抗RNA病毒药物法匹拉韦的抗病毒活性。利巴韦林和法匹拉韦对HTNV感染表现出相似的强效抗病毒活性。当联合使用时,通过添加低剂量法匹拉韦增强了利巴韦林的疗效,突出了提供比目前更好的治疗的可能性。
Ecological changes, population movements and increasing urbanization promote the expansion of hantaviruses, placing humans at high risk of virus transmission and consequent diseases. The currently limited therapeutic options make the development of antiviral strategies an urgent need. Ribavirin is the only antiviral used currently to treat hemorrhagic fever with renal syndrome (HFRS) caused by Hantaan virus (HTNV), even though severe side effects are associated with this drug. We therefore investigated the antiviral activity of favipiravir, a new antiviral agent against RNA viruses. Both ribavirin and favipiravir demonstrated similar potent antiviral activity on HTNV infection. When combined, the efficacy of ribavirin is enhanced through the addition of low dose favipiravir, highlighting the possibility to provide better treatment than is currently available.
