ASK THE DOCTOR:
The ABCs of hepatitis
By DR JIM MITTERANDO
Q - My brother has chronic hepatitis. How is this different than the
recent hepatitis outbreaks at local restaurants?
A - Hepatitis - inflammation of the liver - is most often caused by
viral infections such as Hepatitis A, B or C. Symptoms of acute hepatitis include
jaundice (yellow skin), dark urine, fever, feeling very ill with flu-like symptoms
- nausea, vomiting and headaches.
Hepatitis A
Hepatitis A is spread by infected food handled by someone with hepatitis A
and rarely by contaminated shellfish. It is not common but is quite contagious.
It is rarely fatal but people can be very ill for several weeks. Hepatitis A does
not cause a chronic infection. There is no treatment for hepatitis A infection
but there is a vaccine for its prevention. Food handlers, sewage/septic workers,
people with chronic hepatitis B or C, and travelers to third world countries should
receive the hepatitis A vaccine. People who have been exposed to someone with
hepatitis A can receive a gamma globulin shot that contains antibodies to prevent
an infection.
Hepatitis C
Your brother probably has hepatitis C illness that causes a chronic infection
in most affected people. Hepatitis C is transmitted by blood products (occupational
exposures, IV drug abuse or blood transfusions before 1992) and rarely by sexual
contact. One percent of Americans have chronic hepatitis C. Contracting hepatitis
from blood transfusions these days is extremely rare since donated blood is screened
for hepatitis. Hepatitis C cannot be spread by sharing food or kissing. Some people
with chronic hepatitis C develop cirrhosis (liver failure) or liver cancer. There
is no vaccine against hepatitis C. People with chronic hepatitis C should receive
vaccines against hepatitis A and B.
The anti-viral drugs, interferon and ribavirin, can eradicate chronic hepatitis
C viral infection 50 percent of the time. These drugs can cause severe side effects
and are used in people with liver damage hoping to prevent further scarring of
the liver. People with chronic hepatitis need to avoid alcohol and over-use of
Tylenol (acetaminophen).
Hepatitis B
Hepatitis B is a sexually transmitted disease that can also spread by contact
with blood. Pregnant women are screened for hepatitis B since it can be passed
to the developing fetus. A small percentage of people with hepatitis B can develop
a chronic infection and cirrhosis.
Hepatitis B is common in Asia. Fortunately, it is declining in the United States
since routine childhood vaccination began about 15 years ago. In Massachusetts,
most people under the age of 25 have been vaccinated. Sexually active adults and
health care workers should also receive hepatitis B vaccine.
More information about hepatitis is available at the Centers for Disease Control
web site: www.cdc.gov.
