Deaths Due to HCV Infections Now ExceedThose Due to HIV Infection
7Ly KN et al. Ann Intern Med. 21 February 2012;156(4):271-278; Mahajan, IDSA 2013
Number of HCV-related
deaths may be over
60,000 because of
under-reporting on death
certificates
• In the United States, the annual number of deaths due to HCV infection are increasing, and have risen above that of HIV infection.
• While these data indicate the increasing mortality burden of chronic HCV infection, deaths due to HCV are frequently underreported; thus the accurate mortality is likely to be higher than is captured by death certificates

HCV Can Now Be Cured in Most Patients
• Unlike HIV and HBV infection, HCV infection is a curable disease
• What does cure mean?• Sustained Viral Response
• Undetectable HCV RNA 12 weeks after completion of antiviral therapy for chronic HCV infection1
• Long term morbidity and mortality benefits

Chronic HCV Infection May Lead to Chronic Liver Disease and Liver Cancer
13
Chronic liver disease includes fibrosis, cirrhosis, and hepatic decompensation; HCC=hepatocellular carcinoma.

http://www.cdc.gov/hepatitis/HCV/HCVfaq.htm. Accessed May 8, 2012.
Fibrosis1
Chronic HCV infection can lead to the development of fibrous scar tissue within the liver
Cirrhosis1,2
Over time, fibrosis can progress, causing severe scarring of the liver, restricted blood flow, impaired liver function, and eventually liver failure
HCC3
Cancer of the liver can develop after years of chronic HCV infection
~75% of patients infected with HCV will develop a chronic infection and approximately 65% of those are expected to develop chronic liver disease
Decompensated cirrhosis: Ascites, bleeding gastroesophageal varices, hepatic encephalopathy, and jaundice.
Projected Numbers of Decompensated Cirrhosis and Cases of HCC to Rise Through 2020
14
Decompensated cirrhosis became more common after 1995 and is presently estimated at 11.7% of cirrhosis cases; the number of cases is expected to continue to increase through ~2020 to 2030.
HCC rose steeply after 1990. Based on the model, the incidence of HCV-related HCC is expected to peak after 219 at almost 14,000 cases per year if the risk in HCV-infected persons with fibrosis remains the same.
The best way to reduce the likelihood that someone will
develop severe complications of hepatitis C is to cure the
infection!

NEW CDC Recommendation
– Adults born during 1945 through 1965 should receive one-time testing for HCV without prior ascertainment of HCV risk factor
– Benefits of therapy
• Reduces risk of liver cancer by 70%
• Reduces risk of all-cause mortality by 50%
Baby Boomers (Born in 1945–1965) Account for 76.5% of HCV in the US1
20
An estimated 35% of undiagnosed baby boomers with
HCV currently have advanced fibrosis (F3-F4; bridging
fibrosis to cirrhosis)3

Screening of Baby Boomers May Prevent >120,000 Deaths Due to HCV Infection
› Birth-cohort screening in primary care would identify 86% of all undiagnosed cases in the birth cohort, compared with 21% under risk based screening1
› Cost effectiveness of HCV screening is comparable to cervical cancer or cholesterol screening (cost/QALY gained with protease inhibitor+IFN+RBV = $35,700)

Hepatitis C Antibody (HCV Ab)
• A positive antibody means that your body was exposed to the Hepatitis C virus and antibodies were made
• This does not mean that you have an active HCV infections
• HCV antibody is NOT protective
• HCV antibody will remain positive even after SVR
HCV RNA
• Referred to as “viral load”
• Available as qualitative and quantitative
• Confirms active HCV infection
• Quantitative testing is used to monitor HCV treatment
HCV RNA Testing Has No Prognostic Value
• The level of viremia does not correlate with the severity of liver disease (activity grade or fibrosis stage)
• Does not predict the outcome of HCV infection (resolution vs. persistence)
• Does not predict the natural course of the disease

HCV Antibody Positive and HCV RNA Negative Patients
• If liver function tests are normal no further testing or follow up required
• Patients who have attained sustained viral response with treatment need not have repeated tests for HCV RNA to confirm a cure
• If liver function tests are elevated evaluate for other etiologies of liver disease
Approach to the Patient with Newly Diagnosed HCV
• Patients need to be educated on
• the natural history of disease
• modes of transmission of
• how to avoid transmission to family members
• the availability of effective treatment
• the reassurance that these new highly effective and safe interferon free treatments available are very well tolerated and nothing like the interferon days
• Screen for depression
• Reassurance
• Patients may benefit from referral to a support group
2/10/2017
15
Additional Measures for Newly Diagnosed Patients with HCV
• Vaccinate for hepatitis A and hepatitis B• Counsel for weight loss if appropriate. Obesity
increases likelihood of liver fibrosis• Recommend avoiding doses of acetaminophen
exceeding 1-2 grams per day• Determine presence or absence of cirrhosis• NSAIDs should be avoided in patients with
advanced fibrosis or cirrhosis
Measures to Avoid Transmission of Hepatitis C
• Avoid Sharing Razors or Toothbrushes
• Cover Bleeding Wounds
• Stop Injection Drug Use
• Advise Not to Share Needles and Paraphernalia
Sexual Transmission of HCV
• Risk of Sexual Transmission is Low in Monogamous Heterosexual Relationships
• Many Experts do not Recommend Barrier Protection for Couples that are in a Monogamous Long Term Relationship
• Patients with Multiple Sexual Partners, and Patients with HIV Should Use Barrier Protection

Hepatitis C and Alcohol
• Hepatitis C Infection Rates in Alcoholics are Significantly Higher Than Controls
• Alcohol Use in Patients with HCV Infection Increases Fibrosis Progression Rate, Risk for Liver Cancer and Overall Mortality
• Abstinence from Alcohol is Recommended
• Educate on Synergistic Damage to liver by Alcohol and HCV
• Refer to Alcohol Rehab Programs if appropriate

General Concepts About SelectingHCV Regimens
• Choice of regimen, treatment duration, and use of ribavirin depends on:
• Presence of cirrhosis
• Prior treatment experience
• PEG-RBV failure
• Prior protease inhibitor failure
• Prior sofosbuvir failure
• Genotype
• Genotype 1a vs 1b
• Genotypes 2-6
• Daclatasvir (DCV) + Sofosbuvir (SOF) (Daklinza + Sovaldi)
• Grazoprevir (GRZ)/Elbasvir (EBR) (Zepatier)
• Ledipasvir (LDV)/Sofosbuvir (SOF) (Harvoni)
• Paritaprevir/Ritonavir/Ombitasvir (PTV/RTV/OMV) + Dasabuvir (DSV) (Viekira Pak)
• Velpatasvir (VEL) + Sofosbuvir (SOF) (Epclusa)
• Ribavirin (RBV) required for some regimens in certain populations.

Special Populations
• HIV/HCV Coinfection• ESRD• Decompensated cirrhosis• Post liver transplant
• These patients do have options and need to be referred to a provider that can treat them.
• www.hcvguidelines.org is living document and regularly updated
So now you suspect that your patient has cirrhosis…
Diagnosis of Cirrhosis Changes Approach to Patients with HCV
• Screen for HCC every 6 months• Evaluate for esophageal varices with endoscopy• Avoid all hepatotoxic drugs• Absolutely no alcohol• Refrain from use of NSAIDs including aspirin,
ibuprofen, naproxen, and others due to an increased risk of gastrointestinal bleed, potential for renal toxicity, and impaired response to diuretic therapy.
• Tylenol is ok to use in patients with cirrhosis• Recommend weight loss for obese patients

• Primary complications include:
– Ascites
– Jaundice
– Variceal hemorrhage
– Portosystemic encephalopathy
• Other possible complications include:
– Spontaneous bacterial peritonitis
– Hepatic hydrothorax
– Hepatorenal syndrome
– Portopulmonary hypertension
– Hepatocellular carcinoma

• serum bilirubin,
• serum creatinine
• international normalized ration (INR)
• developed in 2002 by UNOS
• Calculation:
• [0.957 x (Serum creatinine mg/dL) + 0.378 loge (Total bilirubin mg/dL) + 1.12 loge (INR) + 0.64] x 10
• Range: 6 – 40
• equates to estimated 3-month survival rates from 90% to 7%respectively
