Induction of highly pathogenic hepatitis C virus (HCV) causes chronic hepatitis round the world. This virus is easily prone to developing resistance against antiviral drugs because of two viral polymerases that do not possess the proofreading and overlapping reading frame abilities. There is more than one explanation for how this virus builds up resistance against antiviral drug treatments. Assays are now available to detect HCV-resistant variants, based on phenotypic and genotypic assays, and next generation sequencing. But these assays are of a little value at baseline, because they are not influential enough for making therapeutic decisions in HCV patients. Moreover, HCV monitoring is now an essential part of clinical practice. Special patients, such as those with thalassemia, renal transplant due to renal failure, and the patients undergoing hemodialysis, are at higher risk for acquiring this infection. Management of HCV infection in these patient groups is complicated by multiple side effects, including flu-like symptoms, neutropenia, fever, and neuropsychiatric disorders, thus limiting the use of ribavirin and coexisting iron overload. In HCV patients suffering from depression, the treatment may be discontinued because of some defects in neurochemical pathways caused by interferon, which can enhance the level of depression in these patients. In addition, obesity has been found to be a marker of failure of HCV treatment. There will be many resistance tolerant HCV treatment options available in the near future.

丙型肝炎病毒的耐药性:与之抗争的未来前景和策略。

高致病性丙型肝炎病毒(HCV)的诱导导致世界范围内的慢性肝炎。由于两种不具有校对和重叠阅读框功能的病毒聚合酶,该病毒很容易对抗病毒药物产生耐药性。关于这种病毒如何增强对抗病毒药物治疗的抵抗力,有多种解释。现在,基于表型和基因型分析以及下一代测序,可用于检测HCV耐药变异的分析。但是这些检测方法在基线时没有什么价值,因为它们对HCV患者的治疗决策影响不大。此外,HCV监测现在已成为临床实践的重要组成部分。特殊患者,例如地中海贫血,由于肾功能衰竭而进行的肾移植,并且接受血液透析的患者感染此疾病的风险更高。在这些患者组中,HCV感染的管理由于多种副作用而复杂化,包括流感样症状,中性粒细胞减少,发烧和神经精神疾病,从而限制了利巴韦林的使用和铁并存。在患有抑郁症的HCV患者中,由于干扰素会导致神经化学通路中的某些缺陷,因此可能会中止治疗,这会增加这些患者的抑郁水平。另外,已经发现肥胖是HCV治疗失败的标志。在不久的将来,将有许多耐药HCV治疗选择。在这些患者组中,HCV感染的管理由于多种副作用而复杂化,包括流感样症状,中性粒细胞减少,发烧和神经精神疾病,从而限制了利巴韦林的使用和铁并存。在患有抑郁症的HCV患者中,由于干扰素会导致神经化学通路中的某些缺陷,因此可能会中止治疗,这会增加这些患者的抑郁水平。另外,已经发现肥胖是HCV治疗失败的标志。在不久的将来,将有许多耐药HCV治疗选择。在这些患者组中,HCV感染的管理由于多种副作用而复杂化,包括流感样症状,中性粒细胞减少,发烧和神经精神疾病,从而限制了利巴韦林的使用和铁并存。在患有抑郁症的HCV患者中,由于干扰素会导致神经化学通路中的某些缺陷,因此可能会中止治疗,这会增加这些患者的抑郁水平。另外,已经发现肥胖是HCV治疗失败的标志。在不久的将来,将有许多耐药HCV治疗选择。由于干扰素会导致神经化学通路中的某些缺陷,因此可能会中止治疗,从而增加这些患者的抑郁水平。另外,已经发现肥胖是HCV治疗失败的标志。在不久的将来,将有许多耐药HCV治疗选择。由于干扰素会导致神经化学通路中的某些缺陷,因此可能会中止治疗,从而增加这些患者的抑郁水平。另外,已经发现肥胖是HCV治疗失败的标志。在不久的将来,将有许多耐药HCV治疗选择。
