Hepatitis C: Cure and Control, Right Now David L. Thomas Suresh Kumar Tomas Zabransky Dennis Leoutsakas
For persons living with HIV, hepatitis C is a major public health challenge that can and should be controlled.
For persons living with HIV, hepatitis C is a major public health challenge that can and should be controlled. For Persons Living With HIV: 1. HCV is common 2. HCV is clinically severe
Adults and children living with HIV, 2008 Eastern Europe & Central Asia 1.5 million Western & Central Europe 850 000 North America 1.4 million East Asia 850 000 Middle East&North Africa 310 000 Caribbean 240 000 South & South-East Asia 3.8 million Sub-Saharan Africa 22.4 million Latin America 2.0 million Oceania 59 000 33.4 million

Antiretroviral Therapy is not Sufficient to Prevent the Adverse Effects of HIV • Antiretroviral therapy may slow fibrosis progression somewhat and may improve IFN sensitivity
Antiretroviral Therapy is not Sufficient to Prevent the Adverse Effects of HIV • Antiretroviral therapy may slow fibrosis progression somewhat and may improve IFN sensitivity • Antiretroviral therapy is not sufficient to • Reduce the HCV RNA load2 • Restore treatment response3 • Prevent cirrhosis or liver failure4
Survival for 3990 HIV coinfected Persons in Denmark by Years of HAART
Markedly Lower Survival for HIV/HCV coinfected Persons in Denmark: 2000-2005
Markedly Lower Survival for HIV/HCV coinfected Persons in Denmark: 2000-2005
There is More to HIV/HCV Coinfection Than Statistics • Stigma • Neuropsychiatric effects • “Scar” of past IDU • Another “mountain to climb” • New “issues” and expensive medications • Injection flashbacks
For persons living with HIV, hepatitis C is a major public health challenge that can and must be controlled.
HCV Transmission Can be Prevented • Transfusion transmission has stopped where screening is done1 • Nosocomial spread reduced where bloodborne precautions observed2
HCV Transmission Can be Prevented • Transfusion transmission has stopped where screening is done1 • Nosocomial spread reduced where bloodborne precautions observed2 • HCV incidence among IDUs has declined3 1Alter Nat Med 2000; 2Hutin Bull World Heath Organ; 3Amon Clin Infect Dis 2008; Mehta CROI 2010
HCV Infection Can Be Controlled • Testing and counseling • Alcohol; HAV/HBV vaccination; secondary spread Institute of Medicine Report on Chronic Hepatitis, 2010
HCV Infection Can Be Controlled • Testing and counseling • Alcohol; HAV/HBV vaccination; secondary spread • Treatment of chronic infection - cure • Sustained virologic response (SVR) possible1 • SVR: HCV not detected during and 6 mo after treatment 1Torriani NEJM 2004; 2Soriano Antivir Ther 2004
HCV Infection Can Be Cured • Testing and counseling • Treatment of chronic infection • Sustained virologic response is possible1 • Sustained virologic response is durable2 • No recurrence in 77 HIV/HCV coinfected persons followed 4466 months post SVR 1Torriani NEJM 2004; 2Soriano Antivir Ther 2004
HCV Infection Can Be Cured Survival after HCV treatment for 493 with no SVR and 218 with SVR • Testing and counseling • Treatment of chronic infection • Sustained virologic response is possible1 • Sustained virologic response is durable2 • Sustained virologic response prevents death3 Months after HCV treatment 1Torriani NEJM 2004; 2Soriano AntivirTher 2004; 3Berenguer Hepatology 2009
Higher HCV Cure Rates Will Come HCV Protease Inhibitor (Telaprevir) Improves SVR and May Reduce Treatment Duration Standard of care for 24 wks along with PI for first 12 wks Standard of care for 48 wks McHutchisonN Engl J Med 2009

HCV Prevention is Possible, but Not Happening Right Now • Prevention • Harm reduction can work but needs to be intensified and expanded Mehta S, CROI 2010
HCV Control is Possible, but Not Happening Right Now HIV/HCV coinfected patients attending the Johns Hopkins HIV clinic 1999-2003 Mehta SH et al, AIDS, 2006
HCV Control is Possible, but Not Happening Right Now • Treatment • SVR is possible but few HIV/HCV coinfected persons are cured • Most HCV infected persons worldwide have no access to testing • 70% unaware in USA2 1Mehta SH , AIDS, 2006; Grebeley J Viral Hep 2009; 2IOM Report on Chronic Hepatitis, 2010
HCV Control is Possible, but Not Happening Right Now • Treatment • SVR is possible but few HIV/HCV coinfected persons are cured1 • Most HCV infected persons worldwide have no access to testing • 70% unaware in USA2 • Treatment/testing costs are prohibitive 1Mehta SH , AIDS, 2006; Grebeley J Viral Hep 2009; 2IOM Report on Chronic Hepatitis, 2010

For persons living with HIV, hepatitis C is a major public health challenge that can and should be controlled. • Harm reduction intensified • Testing expanded • Treatment possible
Like HIV, HCV Treatment Will Need to Be Expanded to Impact Global Health "Let's rejoice in the fact that today we have treatments that work ... what we need is the political will to go the extra mile to deliver universal access.“ J Montaner
