Liver Functions
Stores: iron, vitamins, minerals, sugars
Produces: bile, cholesterol and lymph
Regulates: blood clotting, glucose, and
hormone levels
Cleans: the blood of bacteria and toxins
11. 11
Liver Functions Cont’d
Processes: food, alcohol and other drugs
Converts: food and drink into forms the body
can use
Oxidizes: triglycerides to produce energy
Basically, the liver processes everything we eat,
drink, swallow, breathe and/or absorb!
12. 12
Liver Damage
Inflammation – immune response
Fibrosis – development of scar tissue
Cirrhosis – a process where liver cells are
destroyed and replaced with scar tissue
Hepatocellular Carcinoma – type of liver cancer
14. 14
What is Hepatitis?
Inflammation of the liver
Caused by viruses, alcohol, medications, and other
toxins
This training will focus on viral hepatitis
16. 16
ABCs… of Viral Hepatitis
Hepatitis A Virus (HAV)
Hepatitis B Virus (HBV)
Hepatitis C Virus (HCV)
Hepatitis D Virus (HDV)
Hepatitis E Virus (HEV)
These viruses all affect the liver but otherwise are unique
17. 17
Viral Hepatitis Language
Acute infection is when the infection is newly acquired,
and is less than 6 months
Chronic infection lasts 6 months or more and is usually
life-long unless treated
Resolved or cleared infection is the body getting rid of
the hepatitis infection – usually in the acute stage
18. 18
Hepatitis A Overview
In 2006, ~32,000 newly infected people in the US
Acute disease -- no chronic infection
Primarily transmitted fecal- oral route
Vaccine is available to prevent infection
19. 19
Reported Cases of Hepatitis A
in Texas 1990-2007
Hepatitis A vaccine licensed in 1995
Hepatitis A vaccine requirements
20. 20
Hepatitis A
Found in the stool (feces) of persons infected with
hepatitis A virus
HAV is usually spread by “fecal-oral transmission”
Putting something in the mouth (food, water, hands) that
has been contaminated with the stool of a person with
hepatitis A
Most infections come from contact with a household
member or sex partner who has hepatitis A
Highly infectious and stable in environment for
months
21. 21
Signs and Symptoms of HAV
jaundice
fatigue
abdominal pain
loss of appetite
nausea
diarrhea
fever
Adults have signs and symptoms more
often than children
Incubation Period: 15-50 days (average 28 days)
22. 22
Persons at Risk for HAV
Household contacts of infected persons
Sex contacts of infected persons
Persons traveling to countries where hepatitis
A is common
Men who have sex with men
Injecting and non-injecting drug users
23. 23
Preventing HAV Infection
Get vaccinated for hepatitis A
Always wash your hands with soap and
water after using the bathroom, changing a
diaper, and before preparing and eating
food
24. 24
Summary of Hepatitis A
HAV is spread the fecal-oral route through
contaminated food or water
There is no long-term infection and you
cannot get it again
The best way to protect against HAV is
vaccination and hand washing
25. 25
Hepatitis B Overview
In 2006 ~ 46,000 new infections in US
~1.4 million in US living with chronic HBV
Primarily transmitted through blood and bodily
fluids

have blood on them (razors, toothbrushes)
32. 32
Preventing HBV Infection
Do not shoot drugs; never share drugs, needles,
syringes, water, or "works"
Consider the risks if you are thinking about
getting a tattoo or body piercing
If you are a health care or public safety worker,
always follow routine barrier precautions and
safely handle needles and other sharps
33. 33
Summary of HBV
HBV is spread through
unprotected sex with an infected person
by sharing drugs, needles, or "works" when using
drugs
through needlesticks or sharps exposures on the
job
from an infected mother to her baby during
birth
The best way to protect against HBV is
vaccination
34. 34
HCV Overview
An estimated 4 million Americans have been
infected with HCV, of whom 3 million are
chronically infected
Most infections are due to illegal injection and
drug use
55%-85% of adults have chronic infection
If resolved, no protective antibodies
No vaccine available
35. 35
Hepatitis C
Inflammation of the liver caused by the hepatitis C
virus (HCV)
HCV can be found in the blood of a person with
hepatitis C
People with hepatitis C may carry the HCV in their
blood for the rest of their lives, and could pass the virus
on to others
Highly infectious, stable in environment for at least 16
hours but not longer than 4 days
36. 36
Transmission of HCV

HCV Transmission
Sources of Infection
51. 51
Sharing Injection Equipment
Studies have found high rates of HCV in IDUs who didn’t share
syringe, but shared cooker, cotton, water or other paraphernalia
People who inject other things (steroids, vitamins and hormones)
may also be at risk
IDUs should use new, sterile equipment every time (clean hands,
injection site and surface too)
CDC recommendation for blood spill clean up
1 part bleach, 10 parts water
52. 52
Sexual Transmission
Seven US studies of long-term discordant partners found
1.5 - 3% seroprevalence of HCV
Other studies of MSM, sex workers, and those with
history of STD found prevalence of 4-6%
Risk may be increased when trauma is present
Other factors related with sexual transmission include #
of partners, the presence of other STDs, and use of
condoms
53. 53
There is a risk with pregnancy (5-6%)
Post-exposure prophylaxis not available
Coinfection with HIV risk increases risk up to 17%
Test infants born to HCV-positive women
Consider testing any children born since woman became infected
Evaluate infected children for chronic liver disease
Breastfeeding ok unless nipples are cracked and/or
bleeding
Mother-to-Infant Transmission
54. 54
Tattooing and Body Piercing
While some studies have found an association between
tattooing and HCV in select populations, (mostly
incarcerated) it is unknown if these can be generalized to
the whole population.
Major concern is non-professional tattooing and/or
piercing
Should use new separate ink containers and new and sterile
needles and other equipment
55. 55
Low/Unknown Risks
Intranasal cocaine/meth use: Some studies have found link
to HCV transmission by blood getting into nasal
membrane from shared snorting items
Crack use: at least one study (Schaefer) found higher rate of
HCV in non-injecting crack users who indicated cracked,
bleeding or burned lips
Personal items with blood on them: anything that
cuts/breaks the skin or membrane (razor, clippers)
56. 56
HCV Survival Outside the Body
One study has been done
Study found HCV alive outside body at 16
hours, 4 days, and 7 days
16 hour sample caused infection, 4 day sample
did not cause infection
57. 57
HIV vs. HCV
Both HIV and HCV are blood-borne infections
HCV is 10 times more infectious than HIV by
blood-to-blood contact
Most co-infected drug users probably were infected
with HCV years before HIV
HIV is more transmissible between sexual partners
and from mother to infant
59. 59
HCV and HIV Coinfection
Up to 240,000 people in the U.S. are co-infected with
HIV/HCV
Majority have chronic disease (85%)
1/3 of HIV+ people are co-infected with HCV
10% of HCV+ people are co-infected with HIV
In urban areas, up to 90% of HIV+ IDUS are co-
infected with HCV
60. 60
Potential Co-infection Effect of HIV
on HCV Disease
HIV infection may worsen HCV disease
Weakened immune system allows HCV to
replicate faster
More infectious because higher viral load
Accelerates and increases disease progression
May not respond well to HCV treatment
61. 61
Potential Co-Infection Effect of HCV
on HIV Disease
HCV disease does not appear to accelerate HIV
disease
Higher toxicity from HAART
As people live longer with HIV, many more HIV
deaths are caused by HCV-related end stage liver
disease
There is still a lot of research to be done on these
effects
64. 64

Prometheus was a Titan. The Centaur Chiron agreed to die because he was suffering from the poison arrow of Hercules. Hercules who helped the underdog killed the vulture or eagle with a poison arrow. The poison was from the blood of the dying hydra.
2-6% of individuals infected with HBV adults progress to chronic infection. Immunizing adults and older adolescents at risk for HBV infection has been recommended since 1982. Despite these facts, infections among adults at risk for infection continue to occur, and the majority of chronic hepatitis B cases in the U.S. are the result of infections acquired in adulthood.
Cases of hepatitis A in Texas have drastically declined since the availability vaccine in 1995. The vaccination recommendations were originally targeted at immunizing children in communities experiencing a lot of disease. From 1990 the incidence of hepatitis A has dropped from 1999, when there were 12.6 cases per 100,000 population to 1.1 cases per 100,000 population in 2008. The success of the hepatitis A decline has been attributed to the vaccination efforts implemented in the state.
The hepatitis B vaccine story begins a bit differently. Vaccines against hepatitis B became widely available in 1986. Immunization strategies originally focused on vaccinating individuals that had high-risk of becoming infected. These strategies to did not make an impact on disease as is demonstrated by the number of reported cases that continued to increase in the mid to late 1980’s. Recommendations to vaccinate all infants routinely began in 1991 and have expanded over the years to include vaccination of adolescents and adults. The incidence of acute case of hepatitis B has steadily been declining since 2004. In 1999 the incidence of disease in Texas was 4 cases per 100,000 population and in 2008 it is 1.1 cases per 100,000 population. The majority of cases of acute hepatitis B occur among individuals between the ages of 24-45 years.
FY 2008 Domestic Enacted Funds National Center for HIV/AIDS, Viral Hepatitis, Sexually Transmitted Disease, and Tuberculosis Prevention (NCHHSTP) funding Division of Viral Hepatitis (DVH) FY 2008, the DVH received $17.6 million, 2% of the NCHHSTP budget domestic HIV activities received 69% of funding (about $640 million) Reminder: 3 to 5 times more people are living with chronic viral hepatitis infections than with HIV infection No significant change in FY 2009 ($18.3 million)
Both HIV and HCV can be transmitted by blood-to blood contract, unprotected sex, and from a mother to an infant; there fore they affect many of the same populations HCV is 10 times more infectious than HIV by direct blood-to-blood contact, which explains the higher incidence of HCV infection among IDUs For this reason and because HCV infection was common in urban areas of the US for decades before HIV was discovered, most HIV/HCV co-infected injection drug users were most likely infected with HCV years before HIV. In contrast, studies have found that HIV is more transmissible than HCV between sexual partners and from mother to her infant. However the risk of sexual transmission of HCV appears to be increased when a person also has HIV. The immuno-suppression caused by HIV may increase HCV viral load, and higher viral load may increase risk of transmitting HCV In untreated HIV positive women, mother-to-infant transmission rates are as high as 20-30%, where as HCV is transmitted to only2% to 5% of infants HCV positive mothers. If the mother is co-infected with HIV the incidence of mother-to-infant HCV transmission has been reported as high as 20%. ****Note: There is no treatment available to HCV+ pregnant women to decrease the likelihood of transmission.
- Coinfection with HIV and Hepatitis C is a significant problem, especially among injection drug users In the United States it estimated that 240,000 persons are infected with both HCV and HIV. Studies estimate that as many as 25-30% of HIV positive people in the United States are coinfected with HCV and up to 10% of HCV positive person are infected with HIV. In urban areas of the US, up to 90% of person who acquired HIV infection from injection drug use also have HCV. HCV accelerated in the setting of HIV: Increased risk for cirrhosis HCV frequently “drives prognosis” in co-infected pts: making treatment more difficult
Most studies indicate that people with HIV/HCV co-infection experience faster progression to cirrhosis and more liver damage than people who are only infected with hepatitis C A weakened immune system allows HCV to replicate faster, and higher HCV viral load makes a person more infectious. Also it may cause individuals not to respond well to HCV treatment
