Etiological classification of hepatitis

Excuse me, do you know about hepatitis? What are its classifications? Maybe this problem is very difficult for many people. We have to do a good understanding of hepatitis, let us go through this article in detail to understand what kind of hepatitis, and help patients understand in detail.
Etiological classification
1. Viral hepatitis: the hepatitis caused by the virus is divided into six kinds of viral hepatitis: hepatitis B, B, C, Ding, e, G and Geng according to their viral series. It can cause swelling of liver cells, and is one of the most widespread and harmful infectious diseases in the world.
In 1908, it was discovered that the virus was also one of the causative factors of hepatitis. In 1947, the original infectious hepatitis (infectious hepatitis) is called hepatitis B (Hepatitis A); HB HA (serum hepatitis) is called hepatitis B (hepatitis B virus (Hepatitis)). Hepatitis B surface antigen was detected for the first time in 1965.
The genetic factors of the six types of viral hepatitis are different. In addition to hepatitis B genetic factor is DNA, the remaining hepatitis B genetic factors are RNA. Among them, the transmission route of hepatitis A is fecal transmission, and the transmission route of hepatitis B is blood transmission, sexual transmission and mother to child transmission.
In addition, viral hepatitis and hepatitis C, hepatitis B, hepatitis E and hepatitis G. In the past, hepatitis viruses, which have been designated as hepatitis viruses, are now identified as a genus of hepatitis B virus, so hepatitis C does not exist.
Vaccines for viral hepatitis, A, B, and D vaccines have been developed; type C, E, and F vaccines are currently not available.
2, alcoholic hepatitis, alcoholic hepatitis: early no obvious symptoms, but the liver pathological changes before the onset, often have a large number of short-term drinking history, significant weight loss, anorexia, nausea, vomiting, body fatigue, fever, abdominal pain and diarrhea, and psychiatric symptoms of upper gastrointestinal bleeding. There are signs of jaundice, hepatomegaly and splenomegaly, and tenderness, pale, swollen and spider nevus ascites, esophageal varices. From the laboratory examination, anemia and neutropenia, red cell volume determination (MCV) than 95FL, serum bilirubin, up to 17.1 moL/L or above, moderately elevated transaminase, often more than 2, the determination of mitochondrial AST (mAST) and total AST (tAST) ratio, the increase of up to 12.5+5.2%. The activity of gamma -GT, glutamate dehydrogenase and alkaline phosphatase increased, and the prothrombin time was prolonged.

3 autoimmune hepatitis: autoimmune hepatitis is rare, and more associated with other autoimmune diseases, is one of the newly identified diseases in recent years. The disease has a higher incidence in Europe and the United States, such as the United States accounted for 10% to 15% of chronic liver disease, China's current coverage of the disease is increasing, it is necessary to improve the understanding of the disease. Autoimmune hepatitis is a group of chronic hepatitis syndromes caused by autoimmunity. It is very similar to viral hepatitis and is often confused with viral hepatitis, but the treatment is very different.
I believe that through the detailed introduction of this article, patients have some knowledge of hepatitis. Hepatitis in our lives is mostly caused by bad habits and habits. Therefore, for the sake of our health, we should form good habits and stop hepatitis
