Introduction
• A RNA virus that used to be known as non-A, non-B hepatitis until it was discovered in 1988
• No vaccine available
• Hepatitis C Antibody
• Does not mean protection
• Exposure vs Infected vs Cured
• Cure, also known as sustained virologic response (SVR), is defined as no detectable HCV in the blood at 12 or more weeks after therapy is complete

Why HCV Can be Cured
HCV RNA remains in the cytoplasm, while HBV and HIV DNA are incorporated into the nucleus of the cell
Nucleus Host Cell Host DNA
Soriano V et al. J Antimicrob Chemother. 2008;62(1):1-4.
What Defines HCV Cure
• In one study, of those patients who reached SVR, 99% had undetectable levels of HCV RNA more than 4 years after treatment end3
• These patients do not experience viral recurrence3
Cure, also known as sustained
virologic response (SVR), is
defined as no detectable HCV
in the blood at 12 or more
weeks after therapy is
complete1,2

CURE
• Cure, or SVR, is associated with improvements in disease complications,
such as rates of hepatocellular carcinoma,
ascites, and variceal bleeding1,2
SVR is also associated
with reduced risk of
all-cause mortality3*
*International, multicenter, long-term follow-up study: 5 large tertiary care hospitals in
Europe and Canada. Patients with chronic HCV infection started an interferon-based
treatment regimen between 1990 and 2003 (n=530).1. Bruno S et al. Hepatology. 2007;45(3):579-587.

Projections
• In a study, approximately 45%
of untreated HCV patients were
projected to develop cirrhosis
by 2030
• HCV is a progressive disease.
Patients who develop
cirrhosis are at greater risk
for developing liver cancer
and other liver-related
complications
Increase in liver complications projected to continue

3. El-Serag HB. Gastroenterology. 2012;142(6):1264-1273.e1.
Costs Associated with HCV Are Projected to Increase
• Aggregate US HCV-related healthcare expenditure estimated to be up to $30 billion per year1
─ Higher costs may be attributed to increasing healthcare utilization, such as
hospitalizations and emergency department visits, by HCV-infected patients2
─ The number of serious long-term complications is expected to increase in the next
decade,1 with the majority of peak costs attributable to more advanced liver diseases
(according to a recent system dynamic modeling study)3

Monitoring in Cured Pts With Advanced Fibrosis
• Routine clinic appointments 1-2 times/yr
– Consider follow up with Hepatologist or Gastroenterologist
• Obtain history and examine for signs of portal HTN
– Thrombocytopenia or Hypersplenism
• HCC surveillance and screening for esophageal varices recommended[1-4]
• Obtain comprehensive metabolic profile, INR, CBC
– Repeat HCV RNA PCR if abnormal LFTs
– Calculate MELD score

Hepatocellular Carcinoma (HCC) :
Surveillance in Advanced Fibrosis
• Ultrasound every 6 mos
– Limited data on CT and MRI
– Alpha-fetoprotein not recommended for screening• Poor sensitivity and specificity
• Remains part of the diagnostic approach for a pt with a liver tumor

Bruix J, et al. Hepatology. 2011;53:1020-1022.
Maintaining Liver Wellness for Pts With SVR: Reinfection
• Counsel and educate on risk reduction
– Sexual transmission
• Partner testing
• Safer sex practices
– Pts using injection drugs should
be
• Referred for treatment
• Counseled on strategies to
avoid HCV transmission
• Vaccinations recommended
– Hepatitis A and B series
– Annual influenza vaccine
– Age appropriate Pneumococcal
vaccination

Maintaining Liver Wellness for Pts With SVR: Alcohol Use
• Most research in pts with ongoing chronic infection
– Alcohol speeds up progression of HCV disease[1-3]
and even replication of HCV[4,5]; abstinence
recommended[6]
• No clear evidence in pts after cure
• Advanced fibrosis: abstinence recommended
• Early fibrosis: mild alcohol use may be permitted[7]
– For men: no more than 4 drinks on any single day AND no more
than 14 drinks per wk
– For women: no more than 3 drinks on any single day AND no
more than 7 drinks per wk

Maintaining Liver Wellness for Pts With SVR: Obesity
• Fatty liver disease is the next epidemic of cirrhosis
• All pts cured of HCV should try to avoid fatty liver disease and additional
liver fibrosis
• Attempt to lose weight if overweight (BMI > 25)
• If present, gain control of diabetes mellitus and dyslipidemia
Ghany M, et al. Hepatology. 2009;49:1335-1374.
Chalasani N, et al. Hepatology. 2012;55:2005-2023.
Case: Post treatment
• Pt cured: testing for HCV RNA at 12 and 24 wks post treatment HCV PCR : undetectable.
• Considerations
– Hepatoma screening: fibrosis status?
• FibroScan prior to treatment = 10.7 kPa; platelet count normal but in low normal range
– Alcohol use: is 1-2 beers on weekends okay?
– Fatty liver disease risk modification: exercise and diet recommendations
• Follow-up schedule
– PCP vs GI -Hepatology
Summary
• Major societal health burden
• Screening for Baby boomers/PWID is important
• Can be treated easily, completely cured, Check for Hepatitis B co-infection
• Cure can lead to decreased cost burden on the health care system in general
• Everyone in the health care can contribute to cure this infection
• Advocate for your patients in places where you work
