    “This paper, which some Drs feel is important, not least for NHS patients in England” :(a leading NHS consultant).

    Prevalence of Resistance-Associated Substitutions in HCV NS5A, NS5B, or NS3 and Outcomes of Treatment with Ledipasvir and Sofosbuvir

    “We evaluated the effects of baseline hepatitis C virus (HCV) NS5A, NS5B, and NS3 resistance-associated substitutions (RASs) on response to the combination of ledipasvir and sofosbuvir, with or without ribavirin, in patients with HCV genotype 1 infection”.

    Good News for GT1s

    Conclusions
    Baseline RASs in NS5A have minimal effects on patients’ response to ledipasvir/sofosbuvir therapy. When these RASs do have effects, they could be largely overcome by extending treatment duration or through treatment intensification.

    Yes, good news, but good to be aware for the small % – So that those in the ‘slow-lane’ can know there is the option to extend treatment if necessary with generics safely via this website in time; especially if they are being treated by NHS England who are not always prescribing the recommended tx period and generally not offering any treatment extention from what I’ve heard.
