April 2014 - 1
Introduction
Advocacy & Self-Advocacy through
Education
The information in this presentation is designed to help
you understand and manage HCV and is not intended as
medical advice. HCV medical care is a partnership
between patients and their medical providers

2
The Liver – A Chemical Factory
Largest internal organ
Size of a football
Approximately 3 lbs in the average
sized male
1.5 quarts of blood flow through it
every minute
www.hcvadvocate.org
3
Liver Functions
Chemical Factory>500 chemical
functions
Bile
Immune System
Detoxifies or Filters
Clotting Factors
Hormones
Regenerates Itself!
www.hcvadvocate.org
4
Keep the Liver Healthy!
If you have HCV – Avoid Alcohol
Avoid mixing drugs – prescription, overthe-counter, herbs/supplements and
street drugs
Eat a healthy, balanced diet based on
MyPlate (www.choosemyplate.gov)
www.hcvadvocate.org
5
Keep the liver healthy!
Get vaccinated!
HAV and HBV vaccines
Avoid toxic substances / fumes
www.hcvadvocate.org
6
Hepatitis C Statistics
U.S. Population
More than 3.9 million Americans
chronically infected
HCV Populations
~1.5 % to 2% Mexican Americans
~3 % African Americans
www.hcvadvocate.org
7
HCV Antibody tests
HCV Elisa II or III
OraQuick
Most common antibody test
whole blood and fingerprick approved
A positive antibody test indicates exposure
It does not indicate current hepatitis C infection
www.hcvadvocate.org
HCV viral load test performed to indicate active HCV
infection
8
Viral Load Tests
Viral Load tests
Hepatitis C RNA by PCR – > 5-10 IU/mL
HCV RNA by branched DNA Assay – > 615 IU/mL
TMA – > 5-10 IU/mL
Why Is a Viral Load Test Important?
To confirm active infection
Somewhat helps to predict treatment response & used to guide
treatment duration
Indication that treatment is working
** Viral load does not correlate with disease progression**
www.hcvadvocate.org
9
Genotype Test
Genotype (1,2,3,4,5,6 and 7)
U.S. population
70% genotype 1
30% genotypes 2 & 3
Why Is a Genotype Test Important?
Guide treatment, what drugs and
treatment duration
www.hcvadvocate.org
10
Liver Biopsy
Test for Determining the Health of the Liver
Measure inflammation, extent of scarring (if
any), Rule out other diseases
Biopsy procedure
Non-invasive markers of liver
inflammation – not yet perfected
FibroScan
www.hcvadvocate.org
11
Transmission- Prevention
Direct blood-to-blood transmission route
Can live on surfaces for up to 6 weeks
Bleach and other disinfectants kill virus,
but probably not inside the needle
Not spread casually – need blood
www.hcvadvocate.org
12
Transmission
Shared
Needles
All Drug
Paraphernalia
Blood Before
1992 - transfused,
Sexual
Transmission
(1-3%)
Mother to
Child 4-7%
Healthcare
Workers –
needle sticks
Shared Household items –
Tattoos /
Piercing
<10% of
routes can not
be identified
www.hcvadvocate.org
products, procedures
razors & toothbrushes
13
Prevention Tips
Injection and Non-Injection Drugs
Do not share needles, cookers, cottons, straws,
pipes, water or any items that might come into
contact with blood
Use bleach to clean – if no needle exchange is
available
People in Stable Long-Term Monogamous
Sexual Relationships
CDC – no need to change current sexual practices
– but there is a risk
www.hcvadvocate.org
14
Prevention Tips
Safer Sex
For so called “high risk groups”
www.hcvadvocate.org
Multiple sexual partners, people with sexually
transmitted diseases, infection with HIV or HBV
Any situation where blood is present
15
Prevention Tips
Mother-to-Child Transmission
Low risk – about 4-7% chance of hepatitis
being transmitted to infant
Given the low rate of transmission,
pregnancy should not be avoided.
Health-Care Settings
Follow standard (universal) precautions
www.hcvadvocate.org
16
Prevention Tips
Tattoos & Piercing
Considered a low/no risk in commercial
setting that practices safety
Make sure disposable needles and separate ink
pots are used and that general safety
precautions are followed
Considered a higher risk in other settings
www.hcvadvocate.org
Non-commercial settings such as in prison,
parties or on the streets
17
Shared Personal Items
Household
Cover cuts or sores
Do not share personal hygiene items
(toothbrushes, razors, etc.)
Professional Personal Care Settings
Standard precautions
Disposable equipment
Bring own equipment (best advice)
www.hcvadvocate.org
18
HCV CAN NOT BE SPREAD BY:
BREASTFEEDING
SNEEZING
HUGGING
COUGHING
www.hcvadvocate.org
FOOD OR WATER
SHARING EATING
UTENSILS OR
DRINKING GLASSES
CASUAL CONTACT
19
Chronic Symptoms
Fatigue – mild to
severe
Flu-like symptoms
(muscle/joint/fever)
‘Brain Fog’
www.hcvadvocate.org
Liver pain
Loss of appetite
Headaches
Gastro problems
and more……
20
Disease Progression
10-25% of HCV positive people
progress on to serious disease usually
over 10-40 years
Fibrosis
Cirrhosis
Light scarring
Compensated vs. decompensated
Steatosis
www.hcvadvocate.org
Fatty deposits in the liver
21
Treatment Decisions
General Treatment
Guidelines
Optimal Response
Stable Health
Active HCV Infection
Compensated Liver
Disease
www.hcvadvocate.org
CC genotype
Younger
Low BMI & Weight
Less Steatosis
Low Viral Load
Minimal Liver
Damage
22
Clinical Data - Treatment
Prospective – well designed clinical trial
with measurable outcomes
Gold Standard
Retrospective – review of data from
previous clinical trials
Important for looking for trends and for
designing future studies
www.hcvadvocate.org
23
Treatment
What is interferon?
What is ribavirin?
General antiviral – immune booster – injection
Antiviral - used only in combination with interferon - pill
or capsule
What is an HCV inhibitor
Direct Acting Antiviral (DAA) – blocks viral replication
www.hcvadvocate.org
24
Approved Medications
Interferon – Pegylated (long-acting interferon)
Ribavirin
HCV Inhibitors
Victrelis (boceprevir) – Merck
Incivek (telaprevir) – Vertex
Olysio (simeprevir) – Janssen
Solvadi (sofosbuvir) – Gilead
www.hcvadvocate.org
25
Treatment - Genotype 2 & 3
Standard of Care:
Sofosbuvir plus ribavirin
Genotype 2 – 12 weeks = 93% cure rate
Genotype 3 – 24 weeks = 84% cure rate
www.hcvadvocate.org
26
Genotype 1 • Standard of care:
• Cure rates up to 90%
• Treatment duration 12 to 48 weeks
• Simeprevir, pegylated interferon plus
ribavirin

Ribavirin can cause birth
defects– black box
warning:
Women of childbearing age, their
partners and female partners of
male patients taking ribavirin must
practice two forms of effective
contraception during to 6 months
post-treatment
Note: the majority of side effects
are from interferon and ribavirin
28

Inject before
bedtime
Drink lots of water
Low doses of
ibuprofen or
acetaminophen
