- You think this is a history lesson,
but let's do some math. What does Hepato meaning "liver" plus
- tropic meaning "infectious
and replicating in the liver" plus DNA (HBV genome) equal? That's right,
- boys and girls, we get the name of the
disease most detrimental to what early Mesopotamian civilizations
- deemed the seat of life--the liver.
-
- The manifestations of
liver diseases such as hepatitis B included jaundice, characterized by
- Hippocrates and found to be infectious as
early as the 8th century. By 1885, hepatitis was found to be
- transmittable through blood tranfusions
and syringes when epidemics of jaundice broke out during the
- wars of the 17th-19th centuries. During
World War II, between 1939-1945, a series of outbreaks occured
- after vaccination for measles and yellow
fever, implying further that the virus was blood-borne.
-
- In 1947, Mac Callum
classified viral hepatitis into two types: Viral Hepatitis A, or infectious hepatitis,
- and Viral Hepatis B, or Seum hepatitis. By
1963, research concerning Hepatitis finally paid off. In 1965,
- Baruch Blumberg, then working at the
National Health Institute (NIH), discovered the Australia antigen
- (later known to be Hepatitis B surface
antigen, or HBsAg) in the blood of aborigines. He had been studying
- samples of sera from multiply
transfused hemophiliacs for polymorphic antibodies, and showed that the
- antigen HBsAg had high presence in
leukemia and Down's syndrome patients. Later in 1968, Prince and
- Okochi isolated the Australia antigen in
hepatis B patients, and from this information, along with the discovery
- of the Dane particle in 1970, the first
vaccine for hepatitis B was produced in 1981 and licensed as "Heptavax."
-
- More than a decade later, the
nation-wide vaccination program on newborns in Taiwan originally launched
- in 1984 showed successful results, with
reported decreases in annual incidence of hepatocellular carcinoma
- in children.
