Advancements in medicine and technology have allowed scientists to discover new diseases as well as treatments for some. Autoimmune hepatitis is among the diseases where a cure in unavailable. In 1950, Waldenström discovered autoimmune hepatitis in young women (Wolf). Originally called lupoid hepatitis, lupus was thought to be the cause of autoimmune hepatitis (Frey, Longe, and Ricker). If symptoms of AIH are detected early, treatment for better life quality can be accomplished with medication instead of transplantation.
The second largest organ in the human body is the liver. It weighs on an average of 3 pounds. It filters out harmful substances in blood and turns what we eat and drink into energy the body can use (American Liver Foundation).The liver is a vital organ in the human body, almost as import as the heart.
Autoimmune hepatitis is life threatening form of liver inflammation, in which the body’s immune system attacks liver cells causing scarring otherwise known as cirrhosis, liver failure, and if not caught in time transplantation (Mayo Clinic Staff). “Scientists don’t know why the body attacks itself in this way, although heredity and prior infections may play a role” (American Liver Foundation).Type 1 of AIH is the most classic case. It can occur at any age and is often developed very fast. Type 2 is less common and is mainly found in young women (American Liver Foundation).Type 3 occurs in adults between the ages of thirty to fifty (Frey, Longe, and Ricker). Type 1 is often accompanied by other autoimmune disorders. Type 1 diabetes, Rheumatoid arthritis, Graves disease, Sjogren syndrome, and inflammatory bowel syndrome are often also seen in patients with autoimmune hepatitis (PubMed Health). About 70 percent of p...

Autoimmune hepatitis is reported to become present after a person is infected with Hepatitis A. Autoimmune hepatitis occurs when the liver is attacked by the body’s immune system. Another complication associated with hepatitis A is relapsing hepatitis.
The Hepatitis B virus is a disease that affects the liver and results in swelling and loss of normal function in the liver. It is estimated that 350 million people are infected with Hepatitis B worldwide, with 50 million new cases diagnosed every year.(1) In the Unit...
Researchers think that this immune system response may be triggered by bacteria or viruses, material in the intestinal contents, or a defective signal from the body’s own cells, called an autoimmune response. Inflammation results in pain, heat, redness, and swelling of the tissue. Chronic inflammation can harm the function of tissues and organs (U.S. News, 2009). Crohn’s disease also appears to affect certain ethnic groups more than others. American Jews of European descent are four to five times more likely to de... ...

Hepatitis B is a DNA viral infection that causes damage and inflammation to the liver. It was first discovered in 1965 by Dr. Baruch Blumberg. The HBV virus is very contagious and is even thought to be the most serious form of viral hepatitis and the most common viral infection on Earth. “HBV is 100 times more infectious than HIV.” (Green, 2002, pg. 7) The virus can survive for about one week outside the body on a dry surface. According to Green (2002, pg. 7), “One in twenty Americans has been infected with the virus at some point in their lives.” Between the ages of 15-39 is when 75% of new HBV infections occur, according to Green (2002, pg.8).
Liver disease resulting from alcohol affects more than two million Americans and is one of the primary causes of illness and death. The liver frees the body of harmful substances, such as alcohol. While the liver breaks down alcohol, it produces toxins that can be even more dangerous than the alcohol consumed (“Beyond Hangovers: Understanding Alcohol's Impact Your Health” 13). “These by-products damage liver cells, promote inflammation, and weaken the body’s natural defenses. Eventually, these problems can disrupt the body’s metabolism and impair the function of other organs” (“Beyond Hangovers: Understanding Alcohol's Impact Your Health” 13). A condition called steatosis is the result of fat build up in the liver and is the earliest stage of alcoholic liver disease. This condition causes the liver difficulty breaking down alcohol, potentially resulting in alcoholic hepatitis. Fibrosis of the liver, which is also related to heavy drinking, causes scar tissue to build up in the liver. The alcohol alters chemicals that the liver needs to break down this scar tissue, causing liver dysfunctions. If one does not refrain from drinking during the condition of fibrosis, the scar tissue can build up and create another condition, called cirrhosis. Cirrhosis is deterioration of the liver resulting from heavy scarring, causing the liver to not be able to function properly. If cirrhosis becomes severe, a liver transplant may be the only solution (“Beyond Hangovers: Understanding Alcohol's Impact Your Health” 14). It is difficult to calculate when a person would develop cirrhosis, because an alcoholic could never develop the disease, but someone who social drinks could. It is also unknown why cirrhosis is more prevalent in women (...

Hepatitis A is a virus or an infection that causes liver disease and inflammation of the liver. According to Centers for Disease and Prevention, hepatitis A is a self- limited disease that does not cause a chronic infection and it is rarely fatal. The virus is an infectious disease of the liver which cannot be transmitted by sneezing and coughing. It is usually transmitted from person to person through the feces or the mouth, from consuming contaminated food or water. Many people do not experience any symptoms of hepatitis A, but if someone was to get it, then the symptoms could last from 2 weeks to 6 weeks. The blood is tested to determine how the liver is functioning. The blood is usually taken from the vein in the arm and
Hepatitis A is an acute infection of the liver that travels through your bloodstream and gastrointestinal tract (2). It is transmitted person to person through fecal contamination. Ingesting contaminated food and water is the main source, this usually occurs when an infected food handler prepares food without appropriate hand hygiene (3). Outbreaks are fairly common in institutions, prisons and military forces. An early infection of Hepatitis A can mimic the flu with symptoms such as being febrile, lethargy, nausea, anorexia, abdominal discomfort and eventually causing severe jaundice (1). This virus can progress and cause liver failure and even death if not treated promptly (3).
