Hepatitis is an inflammation of the liver. It can be transmitted by viruses, or it can develop independently - against the background of poisoning with poisons or as a result of human autoimmune diseases. Regardless of the etiology, liver inflammation can be acute or chronic.
Hepatitis is an acute or chronic inflammation of the liver. There are both viral and other types of hepatitis.
Hepatitis can be acute or chronic. The acute form most often occurs as a result of poisoning with poisons, drugs, etc. The chronic form of hepatitis can be the result of prolonged exposure to toxic substances (alcohol, some drugs, etc.), develop against the background of acute viral hepatitis, or arise as a result of autoimmune diseases.
Forms of hepatitis that are not transmitted by viruses include toxic, radiation hepatitis and liver inflammation associated with impaired functioning of the immune system.
Toxic hepatitis occurs as a result of acute or chronic poisoning of the body with various poisonous substances and certain medications. A particularly severe form of liver inflammation is caused by poisoning with pale toadstool toxins, carbon tetrachloride, white phosphorus and industrial poisons.
Most often, toxic hepatitis occurs while taking drugs such as allopurinol, ibuprofen, tetracycline, hormonal contraceptives, isoniazid, halothane, methyldopa and some other pharmaceuticals. The sensitivity of the liver to drugs is individual for each person, but in general, we can say that toxic hepatitis can be caused by almost any drug.
Inflammation of the liver may be due to autoimmune diseases. Women are at risk for autoimmune hepatitis. On average, 15 to 20 people fall ill with the autoimmune form of hepatitis per 100,000 population. This type of liver inflammation develops due to dysfunction of the immune system, when the human body begins to produce antibodies that destroy liver tissue. Usually, with autoimmune hepatitis, not only the liver is affected, but also other internal organs - the thyroid gland, salivary glands, and pancreas.
Hepatitis A, B, C, D, E and F have viral etiology and can be transmitted from person to person. The most famous of the viral hepatitis are hepatitis A and hepatitis C. Hepatitis A is transmitted by RNA viruses and leads to the destruction of liver cells. Hepatitis C is caused by the HCV virus and is transmitted through contact with the blood of an infected person. There is currently no vaccine for it.
