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

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)
