6 Global HCV burden and genotype distribution 6 HCV genotypes (GT 1 6) GT 1 and GT 4 predominate in Egypt and Middle East Messina JP, et al. Hepatol 2014; doi: /hep GT: genotype

7 HCV a uniquely Egyptian epidemic Egypt s HCV burden is at least 4 x greater than that of any other country 1 in 7 sero-positive (global average 1 in 50) But, not only is the Egyptian HCV problem one of size, the prevalent GT 4 is one that is not commonly found in the rest of the world Drug development has primarily focused on GT 1 to date Yahia M, Nature 2011:474:S12 3

8 The unique Egyptian situation requires a unique approach to HCV management Number of individuals with late-stage liver disease is projected to increase 1 Although Egypt now has the world s largest HCV treatment programme, 2 the current treatment rate and efficacy are not sufficient to manage the disease burden 1 The National Treatment Programme needs to evolve with the availability of new drugs 1.

14 Challenges for liver transplantation in Egypt Cadaveric organ donation is illegal in Egypt Many patients travel to America, Europe or China Living donor liver transplantation (LDLT) has provided the only option for patients with ESLD Donor must be the patient s relative, between years old and free of any diseases Concerns over organ donation for money In Western countries, the average waiting time for an overseas patient to receive a cadaveric graft is months Significant mortality during this waiting period 1.

35 Summary taking HCV out of the transplant equation The future is more optimistic for patients with HCV-related ESLD Clear evidence that re-infection post-lt can be prevented by treating HCV before the procedure and cured afterwards with effective DAA treatment, even in those with the severest form of disease SOF + RBV data show promise high efficacy and no DDIs with common immunosuppressant agents To put progress into practice in Egypt, a transformation in management approach is required so that patients are cured of HCV before they require a transplant

37 Hepatology on the Nile 2 Putting Progress into Practice for HCV Care in Egypt Cairo, 25 September 2014 Meeting Close Maria Buti Autónoma University, Barcelona; Chief of Internal Medicine and Hepatology, Vall d Hebron University Hospital, Barcelona, Spain

38 Vision for future treatment of chronic HCV: Putting progress into practice ALL PATIENTS ALL HCV GTs 1 6 including BOC/TVR failures including decompensated cirrhosis Including HIV/HCV co-infection 1 Pill/day for 8 12 wks Simple prescribing Treatment uptake Health burden

39 Putting progress into practice for HCV care in Egypt: Summary Recent advances, once accessible, have the potential to transform and simplify patient management New potent, pangenotypic, well tolerated IFN-limiting and IFN-free treatment options of short duration are emerging Need to prioritise and treat now those patients with greatest need Need to preventing the currently high rates of reinfection through appropriate hygiene manoeuvers
