  2. Number of deaths/year from selected conditions, 2010 1.4 million people died in 2010 of viral hepatitis Source: Global Burden of Disease Study 2010 Lozano et al, Lancet 2012

  3. Estimated annual deaths from selected causes by region, 2010 Source:Courtesy of IHME – Global Burden of Disease Study

  4. Number of hepatitis deaths by virus type and disease outcome, 2010 Most deaths are due to chronic hepatitis B and C E Source: Global Burden of Disease Study 2010 Lozano et al, Lancet 2012

  5. Global prevalence of hepatitis C infection, 2005 adults (19-49 years), by GBD region Source:Hannafiah et al. Hepatology 2013

  6. Prevalence of HCV among persons who inject drugs • HCV prevalence in PWID >50% in most countries; between 60-80% in 25 countries • and >80% in 12 countries Nelson et al. Global epidemiology of hepatitis B and hepatitis C in people who inject drugs: results of systematic reviews. Lancet, 378 (9791), 2011.

  9. WHO's Hepatitis area of work: evolution… 2010 2011 2012 2013 2014 2015 (and beyond) World Health Assembly Resolution on Viral Hepatitis Establishment of Global Hepatitis Programme (GHP) Reorganization of Global Hepatitis Programme WHA resolution STAC-Hep Global Framework Implementation of Resolution And Global Action Plan • Hep B immunization • Blood/injection safety • Outbreak control • Water and sanitation

  11. Global Hepatitis Framework: Goals • Within a health systems framework: • Reduce transmission • Reduce morbidity and mortality and improve treatment and care of patients • Reduce the socio-economic impact at individual, community and population levels • Entry-point to link with and support other critical organizational priorities, including • universal health coverage • affordable access to commodities • health inequities

  12. Global Hepatitis Framework: Four Axes Axis 1: Partnerships, resource mobilization and communication Axis 2: Data for policy and action Axis 3: Prevention of virus transmission Axis 4: Screening, care and treatment

  13. Axis 1: Increasing engagement through awareness, partnerships and mobilizing resources • Status: • Low levels of awareness, engagement, political action, financial commitment • Actions and plans: • Promotion of World Hepatitis Day commemoration • Establish Global Hepatitis Network • Global Hepatitis Policy Report • Global Partners’ meeting on hepatitis • Formation of civil-society reference group

  14. World Hepatitis Day 2013 sample posters

  15. WHO Global Policy Report 2013 • Aim: To assess WHO Member States' response to hepatitis – in the context of the WHO Resolution 63.18 • Conducted in collaboration with World Hepatitis Alliance • Response rate: 125 of 194 (64%)Member States

  16. Axis 2: Evidence-based policy and data for action • Status: • Weak surveillance systems leading to poor quality of country-level data on burden of infection and disease outcomes • Lack of reporting system to monitor implementation of treatment scale-up • Actions: • Publish global prevalence and burden estimates for viral hepatitis • Develop guidelines for hepatitis surveillance in low- and middle-income countries

  17. WHO sponsored systematic reviews of hepatitis prevalence data

  18. Axis 2: Evidence-based policy and data for action • Plans: • Establish modelling reference group • Conduct regional adaptation workshops of surveillance guidance • Conduct country hepatitis burden-of-disease and national planning workshops • Develop a monitoring and reporting framework for assessing country and global hepatitis response

  19. Axis 3: Prevention of virus transmission • Status: Effective prevention measures exist but level of implementation is variable • Actions: • Blood safety: • policy guidance and technical assistance to countries for • universal access to safe blood and blood products • self-sufficiency in safe blood and blood products based on voluntary unpaid blood donation • Injection safety: • SIGN Network • WHO-UNICEF-UNFPA for exclusive use of auto-disable syringes in immunization services • Promotion of harm-reduction guidance and services

  20. Axis 3: Prevention of virus transmission • Plans: • Immunization: • Promotion of birth dose administration • Hepatitis E vaccine SAGE working group • Blood safety: • Continued emphasis on implementation of policies • Injection Safety: • Launch of Global Injection Safety Campaign

  21. Axis 4: Treatment • Status: • Dramatic advances in treatment options • Very low levels of: • Awareness among general public and health-care workers • Access to screening • High-quality, low-cost diagnostics • Laboratory infrastructure • Treatment uptake • New WHO hepatitis treatment guidelines

  22. WHO’s role in improving access to hepatitis therapy • Screening • Care • Treatment Treatment Guidelines Prequalification of generic medicines Essential Medicines List Advocacy, guidance and technical assistance for improved treatment access Multi-stakeholder engagement World Hepatitis Day observance Improved prevalence estimates Prequalification of diagnostics Screening/ testing guidelines

  23. Topics for WHO hepatitis C screening, care and treatment guidelines Who should be tested for hepatitis C (antibodies)? When to confirm HCV infection (PCR)? When to start treatment? What medicines to use? What interventions to slow progression of liver disease? How to assess degree of liver fibrosis/cirrhosis? How to monitor for response to treatment and drug adverse reactions?

  24. New Opportunities for treatment scale-up • Current treatment regimens are complex, costly (drugs and monitoring) and have significant toxicities • Dramatic new treatment results, high SVR rates, oral regimens, pan-genotype and high safety profile • WHO published it’s first ever hepatitis C treatment guidelines in April 2014 • Successful price reductions, • Egypt $900 for a 12 week course of sofosbuvir • USA $84,000 in comparison

  25. WHO recommendations on diagnosis and treatment of hepatitis C in PWID • Screen PWID • anti-HCV antibodies • rapid testing vs serology • Diagnosis • HCV RNA • Reduce alcohol intake • Staging • liver biopsy • non – invasive test • Treatment • genotype 1,2,3,4 • sofosbuvir • pegylated interferon and ribavirin • genotype 1 • telaprovrevir or bocepravir • genotype 1b & 1a (without Q80K polymorphism) • simepravir

  39. Case example - Ukraine • Before • example of OST / HIV / TB in Ukraine many years ago • OST on one side of town, HIV medication on another • no OST in TB hospital… • Now • multiple models of care • ARVs in narcology dispensaries • OST in HIV services • both ARV and OST in primary care and public hospitals

  40. Collaboration of 150 NGOs, organised HCV treatment for co-infected individuals • Negotiated price reduction of interferon and ribavirin from $20,000 to $5,000 dollars per course • Decentralised approach • “Aids Clinic” • OST clinics • Community Clinics • Integrated into harm reduction/ART delivery. • Doctors providing the majority of care • Estimated to have treated 100 people, • Issues now with the political instability and clinics in Crimea and Eastern Ukraine have closed

  41. Case example - Tanzania • Muhimbili medical centre • integrated treatment in an outbuilding of a district hospital • developed by infectious disease unit • integrated treatment: • drug dependence • HIV • TB • other conditions • daily dispensing: • methadone • ARV • TB treatment

  42. ‘One-stop-shop’ Drug dependence treatment Family support Mental health care Drug user Overdose, HIV, Hepatitis prevention Social assistance & protection Antiretroviral therapy General health care
