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.
