  2. Global burden of Hepatitis C virus infection: Europe Cornberg M et al Liver International 2011; 31 (Suppl 2):30-60

  3. Global Burden of HCV:Barriers to Testing, Care, Treatment • Developed countries • Most HCV-infected persons are unaware of their infection • Inadequate knowledge and awareness of HCV among healthcare providers and their patients • Cost-related factors • Lack of HCV screening policies • Developing countries • Same barriers as in developed countries, plus • Low political, provider, and community awareness of HCV as a significant health threat • Lack of understanding among public health officials on the true burden of disease • One-third of the WHO Member Countries do not collect prevalence data for viral hepatitis Averhoff FM, et al. Clin Infect Dis. 2012;55(suppl 1):S10-S15.

  4. Hepatitis C in Ireland Number of notifications of hepatitis C 2004-2010, by sex and mean age By 2013, 12,365 diagnosed Prevalence is 20,000-50,000

  5. Mean annual notification rates per 100,000 for hepatitis C by age and sex, 2004-2012

  6. Most likely risk factor (%) for cases of hepatitis C notified 2007-2010 (where data available, n=2772, 50%)

  7. Most likely risk factor (%) for cases of hepatitis C notified 2007-2010 (where data available, n=2772, 50%) HCV genotypes 1 and 3 are the most common

  8. In Ireland, 62–79% of injection drug users are positive for anti-HCV Prevalence of HCV among injection drug users in Ireland 62–79% Fitzgerald et al. IMJ 2001;170:32 Grogan et al.

  9. Epidemiology in Ireland: Prisons 17–21% started injecting drugs in prison Department of Community Health and General Practice, Trinity College, Dublin. Hepatitis B, Hepatitis C and HIV In Irish Prisoners, Part II:Prevalence and Risk in Committal Prisoners 1999

  10. Epidemiology: Ireland • No seroprevalence data from general population • Of 62,667 women screened in the anti-D RhIg Programme, seroprevalence of HCV Ab positivity was 1.1%Kenny-Walsh et al, NEJM1999;340:1228 • Optional HCV Screening Programme of transfusion recipients, 1995 – 2002: 14,917 individuals screened (85% female) with seroprevalence rate of 0.3% Davoren et al, Transfusion 2002;42:1501

  11. HCV and the individual • 10–20% of patients with HCV will develop cirrhosis after 20–30 years EASL. J Hepatol 2014;60:392–42

  23. A viral cure can be achieved in HCV infection Achievement of a sustained virologic response (SVR) following completion of treatment is indicative of successful therapy and is synonymous with a cure Acute Infection Chronic Infection Successful Therapy Soriano V, et al. J Antimicrob Chemother. 2008;62:1–4. Smith BD, et al. MMWR. 2012;61(4):1-32. Metzner KJ. Future Virol. 2006;1:377-91

  24. Does SVR equal cure of liver disease? • Viral eradication stops progression of disease • Mild Disease - long-term outcome = pop’n risk 286 pts with SVR after IFN therapy Follow-up post SVR (n=286) SVRs (n=286) Survival Matched general population Proportion of patients % survival Decompensation/HCC Time [yrs] Time [yrs] Veldt Gut 2002

  25. SVR saves lives Long-term follow-up of patients with cirrhosis post-treatment Non-SVR SVR SVR eliminates liver failure Van de Meer et al 2012

  26. Benefits of SVR: reduction in liver-related disease Number of events Mortality Rates and Hospital Episode Rates (Per 100 Person Years) by SVR Status Observed Among 1,215 Post-Treatment HCV Patients in Scotland, 1996-2007 Innes HA et al. Hepatology 2011;54:1547-1558.

  27. Bottom line Non-Cirrhotics • SVR = cure  normal life expectancy Cirrhotics • SVR eliminates liver failure • SVR greatly reduces the risk of HCC • SVR improves liver-related AND overall survival In a cost curtailed environment is curing a disease more effective than managing a disease - diabetes versus HCV?

  33. Current Challenges - unmet need We apologise that this information is not able to shared online as it is unpublished data

  34. HCV in Ireland: where is it? Three big reservoirs • Current injectors • Ex-injectors • Hidden • Finding them may take a screening campaign (‘baby boomers’) • Immigrants • Pattern of infection unpredictable (‘healthy migrant’ effect) • Access can be difficult • Not everyone wants to be associated with these virus

  35. Barriers to HCV Care HCV Infection HCV Infection Patient factors Social support homelessness, social isolation, culture, stigmatisation, language and ethnicity Treatment side-effects Patient fears and impact on quality of life and career Cost Financial concerns around treatment and daily living costs and lack of funding support HCP factors Lack of education Lack of awareness of HCV among primary care staff Lack of screening and referral facilities Lack of communication with specialist services Clinician bias Lack of urgency from the Department of Health and HSE. Diagnosis Diagnosis Referral to Specialist Referral to Specialist

  36. What will it take to overcome current barriers? Future: better treatments • Simpler therapy • Shorter duration • More tolerable • Efficacious Opportunity to reduce morbidity, mortality and associated healthcare costs

  37. What will it take to overcome current barriers? • Advocacy • Leadership • Political partnership

  38. I.C.O.R.N. • Irish Hepatitis C Outcomes Research Network. Established February 2012. • Collaboration between ISG, IDSI, NCPE and HPSC, research networks, and pharma. • The goal of this collaboration is to optimise the quality of care of patients with hepatitis C (HCV) treated with direct-acting antiviral therapy.

  39. I.C.O.R.N. • to provide a governance structure and stewardship programme for clinicians and clinical nurse specialists • develop national treatment guidelines • establishment of national treatment HCV registry • platform for HCV clinical trials and HCV related research • R&D models of care to enhance equitable access to services for all assess differing treatment models

  40. DAAs – decision to reimburse We apologise that this information is not able to shared online as it is unpublished data

  41. Outputs from registry • Real time e-data capture tool developed by ICORN (A O’Leary) in conjunction with DCCR (J. McCourt, R. Gaur) • Real-world, observational data • Effectiveness vs efficacy • Analysis of response modifiers • Quantitative analysis of adverse events • Economic consequences • PROMs and PREMs

  42. ICORN HCV Roadmap 2014 • Development of Model of Care - Network of treatment sites • Expansion of Registry • Advocacy for Implementation of National HCV Strategy • Education and awareness • Surveillance and screening • Infrastructural programmatic support to consolidate national programme

  43. 36 recommendations across four key areas: • Surveillance • Education & Prevention • Screening • Treatment access & delivery

  44. Reality or Fantasy • Will screening be acceptable in primary and care? • Who will pay? • Does infrastructure exist for referral and treatment? • New models for care? Who will treat?

  45. Lessons from Scottish HCV Plan • Epidemiologic data KEY factor, data linkage techniques developed • Clinician and Public Health leadership • Advocacy and support groups • Strong governance • Programme managed • Political partnership
