Hepatitis Q&A

by Leo Treyzon, MD

The Liver

The liver is the largest organ in the body. It is found high in the right upper abdomen, behind the ribs. It is a very complex organ and has many functions. They include:

  • Storing energy in the form of sugar (glucose)
  • Storing vitamins, iron, and other minerals
  • Making proteins, including blood clotting factors, to keep the body healthy and help it grow
  • Processing worn out red blood cells
  • Making bile which is needed for food digestion
  • Metabolizing or breaking down many medications and alcohol
  • Killing germs that enter the body through the intestine

The liver is a resilient organ and has the capacity to regenerate. However, the liver is also subject to illnesses that can lead to permanent damage. One example is autoimmune hepatitis, a condition in which the body fights against its own liver.

What is Hepatitis?

When cells in the body are injured by such things as chemicals or infection, the area that is wounded becomes inflamed. Hepatitis is inflammation of the liver, which in turn causes damage to individual liver cells. It is most often caused by viral infection. However, it can also be caused by alcohol, certain drugs, chemicals or poisons, or other diseases.

Hepatitis may be either acute or chronic. In acute hepatitis, the inflammation develops quickly and lasts only a short period of time. The patient usually recovers completely, but it can take up to several months. Occasionally, a person fails to recover fully, and the hepatitis becomes chronic. Chronic hepatitis can develop over a number of years without the patient ever having acute hepatitis or even feeling sick. As the liver repairs itself, fibrous tissue develops, much like a scar forms after a cut or injury to the skin heals. Advanced scarring of the liver is called cirrhosis. Over time, cirrhosis irreversibly damages the liver, eventually resulting in liver failure.

What is Autoimmune Hepatitis?

The immune system consists of different types of white blood cells that help to fight infections. Some of these cells produce antibodies. Antibodies defend the body by destroying bacteria, viruses, and other foreign materials. There are different kinds of antibodies, each fighting against a specific foreign substance. Thus, the immune system protects the body against outside invasion by germs. But sometimes, the immune system mistakenly recognizes the body’s own organs as foreign. It can develop antibodies against these organs. This can cause various illnesses, such as rheumatoid arthritis and lupus. These illnesses are called autoimmune disorders because the body is literally fighting against itself.

When the immune system attacks the liver in this way, it is called autoimmune hepatitis. Autoimmune hepatitis is not caused by a virus or bacteria, so it is not a contagious disease. Exactly what triggers the immune system against the liver is unknown. The inflammation is usually chronic, and without treatment it can cause serious injury to the liver.

What is Hepatitis B?

Hepatitis B is caused by the hepatitis B virus (medically abbreviated as HBV). Current estimates are that over 250,000 people in the United States contract HBV each year. It is often spread through sexual contact, accounting for about 50% of the reported cases. It is also spread through contact with blood or body fluids from a person carrying HBV. Some groups have a higher risk of becoming infected with HBV. These include:

  • Intravenous drug users
  • Health care workers, funeral workers, police
  • People in an HBV infected person’s household
  • People with multiple heterosexual or, especially, homosexual partners
  • Residents of nursing homes
  • Hemophiliac and hemodialysis patients
  • Prisoners and prison workers
  • Travelers to underdeveloped countries
  • Certain ethnic groups such as Asians, Hispanics, American Indians, Alaskan Natives, or people from developing countries


In pregnancy, the virus is passed from an infected mother to her child in about 90% of the cases. This usually occurs during delivery. HBV is also carried in breast milk. In about 30% of all cases of hepatitis B, however, it is unknown how the patient contracted the virus.

HBV is much more contagious than the AIDS virus. For example, it can live outside the body on a dry surface for up to 10 days. Once a person gets the virus, it may take from one to six months for the infection and symptoms to develop. One of three things can then happen—most patients develop acute Hepatitis B and recover completely; a small percentage become HBV carriers; and some develop chronic Hepatitis B.

What is Hepatitis C?

Hepatitis C is caused by a virus (medically abbreviated as HCV). This type of viral hepatitis is different from the others in an important way. All patients with hepatitis A and most with hepatitis B develop an acute infection, recover completely, and develop antibodies that protect them from ever getting the disease again. Once inside the body, it changes its form to evade discovery and attack by the immune system. Scientists have already identified many forms of HCV, and patients infected with one type are not necessarily safe from other types. Hepatitis C patients do develop antibodies, but they are not curative or protective as in hepatitis A or B. Hepatitis C antibodies may not completely rid the body of the virus. Therefore, most people infected with the HCV virus will develop chronic hepatitis.

Current estimates are that 3.5 million Americans carry the virus that causes hepatitis C, and 150,000 people become infected with HCV each year. This virus is known to be spread through infected blood, blood products, and needles. Prior to the late 1980s, people were most at risk for contracting the disease through blood transfusions. However, a blood test was developed at that time to detect the virus, and the blood supply is now always tested to prevent spread of the disease in this way. Even so, there is a very slight risk for those who must receive blood products on a regular basis, such as hemophiliacs and patients on hemodialysis. Healthcare workers are also at risk. At this time, the people most at risk for getting hepatitis C are IV drug users who share needles. There are also a larger number of cases among East Asians. In about 40% of all cases of hepatitis C, it is unknown how the patient was infected with the virus. This situation is known as community acquired disease.

What is Chronic Hepatitis C?

Hepatitis C is a cause for concern for two reasons. First, most cases become chronic. Second, patients seldom become acutely ill, so it is possible for them to have the disease for some time before it is diagnosed. Late in the disease, fatigue may become increasingly severe. If cirrhosis has developed, other more serious symptoms may occur. However, the elevation in the blood ALT may not correlate with the degree of liver inflammation. In other words, a high ALT may not necessarily mean there is a serious degree of inflammation. Conversely, a low or normal blood ALT level may be present even though there is chronic liver damage. For this reason, a liver biopsy is almost always required to determine how serious the disease may be. Under. A biopsy can show if cirrhosis is present and how far it has progressed. It is believed that about 20% of the patients with chronic hepatitis C will develop cirrhosis, and a few of those will go on to develop liver cancer. It may take from 10 to 40 years for serious liver damage to occur.
