1 Hepatitis C “Hidden Harm” Prof Suzanne Norris Consultant Hepatologist St James’s Hospital Trinity College Dublin

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 Number of notifications of hepatitis C 2004-2010, by sex and mean age Hepatitis C in Ireland 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 HCV genotypes 1 and 3 are the most common

8 Prevalence of HCV among injection drug users in Ireland In Ireland, 62–79% of injection drug users are positive for anti-HCV 62–79% Fitzgerald et al. IMJ 2001;170:32 Grogan et al. IMJ 2005;174(2):14 Smyth et al. Addiction 1998;93(11):1649 Smyth et al. J Epid Com Health 2003;57;310 Cullen et al. IMJ 2003;172(3):1213

9 Epidemiology in Ireland: Prisons Prevalence rate Prison census survey (n=1205) Committal survey (n=607) HBV9%6% HCV37% (81% IDU)22% (72% IDU) HIV2% 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 17–21% started injecting drugs in prison

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

12 Risk factors that may affect progression of HCV Infection Factors contributing added risk to developing cirrhosis or HCC Steatohepatitis/obesity 1 Diabetes 2 HIV coinfection 1 Presence of varices 2 Hepatitis B coinfection 1 Low platelet count 2 Alcohol intake 1 Increasing age 2 Smoking 1 Black ethnic group 2

16 Indirect economic costs of HCV Data from the 2009 US National Health and Wellness Survey showed patients with HCV were significantly less likely to be employed vs controls ( p<0.0001). HCV in the EU population significantly impacts several domains of HRQL (p<0.05) DiBonaventura M et al. J Med Econ 2011;14:253–61 DiBonaventura M et al.

17 REVEAL Study: risk of chronic HCV infection on hepatic and extrahepatic deaths Community based, long-term, prospective study –Invited 89,293 residents (aged 30-65 years) from 7 townships in Taiwan 23,820 (26.7%) agreed to participate Current analysis (n=19,636 HBsAg-negative) –Anti-HCV seronegative (n=18,541) –Anti-HCV seropositive (n=1095) Detectable HCV RNA: 69.4% 2394 deaths over 317,742 person-years of follow-up –Average follow-up: 16.2 years –Overall mortality: 753.4 per 100,000 person-years REVEAL: Risk Evaluation of Viral Load Elevation and Associated Liver Disease/Cancer.

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 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 Acute Infection Chronic Infection Successful Therapy

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

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

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?

31 HCV mono-infection landscape in Ireland We apologise that this information is not able to shared online as it is unpublished data

32 HCV mono-infection treatment programme in St James’s Hospital We apologise that this information is not able to shared online as it is unpublished data

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 HCV Infection Diagnosis Referral to Specialist Barriers to HCV Care HCV Infection Diagnosis Referral to Specialist 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.

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

39 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.

40 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

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

42 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

43 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

44 36 recommendations across four key areas : –Surveillance –Education & Prevention –Screening –Treatment access & delivery

45 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?

46 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
