Chronic Hepatitis C Brief History 1970: elevated AST/ALT No disease 1980: NonA-NonB hepatitis Mild disease 1990: HCV infection Major Health Problem 2000: Combination therapy (PR) high SVR 2010: New drugs (PIs) for selected patients 2014 : Combination of new drugs with multiple targets 20??: Final victory??? For whom?? With what???
The future of HCV infection Parameters Epidemiology new infections risk population Prevention strategies- vaccines Burden of the disease physical history Therapy efficacy- safety - adherence target population Access to drugs Cost of new drugs Health policy- political will
Hepatitis C burden of the disease It is estimated that in the next decade 1 it will be a: 50% increase of cirrhosis 100-200% increase of decompensated cirrhosis 50% increase of HCC cases 500% increase in the number of patients that they will need transplantation. It is quite clear that chronic HCV infection would have a great impact on health economics the forthcoming years. Ward, Top Antivir. Med, 2013; Davis et al 2010; Pyenson et al 2009

The Advantages of real life studies non-selected population comorbidities (HIV coinfection, renal disease, old age, immune diseases..) broad range of liver disease (early stage decompensated cirrhosis-post OLT) realistic therapy adherence (side effects, number of pills, duration of treatment ) evaluation of complex therapies and drug-drug interactions useful to detect rare or late side effects routine practice setting logistical, ethical feasibility and applicability health policy and health economics

In summary from the clinical studies and real world data in the case of sofosbuvir/ledipasvir Effective in special populations HIV coinfection, old age, immune diseases..) Effective in all the spectrum of liver disease early stage, cirrhosis, decompensated cirrhosis, post OLT) Excellent therapy adherence minor side effects or absence of side effects in the majority of patients one or only a few number of pills daily short duration of treatment 12 wks (8 wks or 24 wks in certain cases)
In summary from the clinical studies and the real world data in the case of sofosbuvir/ledipasvir Friedly environment for drug-drug interactions Absence of late side effects Logistical and ethical feasibility relates mostly to cost not related with this combination only general approach and limitations to use DAAs Cost is a major issue for health policy and health economics
Treatment of HCV infection The revolution We never had drugs with such and efficacy and safe profile for such a great number of patients Target: To cure all HCV patients with DAAs
