Common types of viral hepatitis include Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, and Hepatitis E, as well as Hepatitis G. Infections by the Epstein-Barr virus and cytomegalovirus can also potentially cause liver damage. Of course, there are other related viral infections that can lead to liver damage and can be classified as viral hepatitis. Different types of viral hepatitis have different transmission routes and methods, and their prognosis and outcomes vary. Appropriate measures should be taken based on the specific circumstances.

Viral hepatitis is what kind of inflammation?

Viral hepatitis is caused by infection with hepatitis viruses, resulting in liver damage and is somewhat contagious, commonly including types A, B, C, D, and E, totaling five types. In fact, the hepatitis virus itself may not cause liver damage directly, rather it is the immune responses triggered by the infection that lead to immunological damage. Thus, viral hepatitis is essentially an immune-mediated inflammation. Different types of viral hepatitis have different outcomes and prognoses. The transmission routes of viral hepatitis mainly fall into two categories: hepatitis A and E are primarily transmitted via the fecal-oral route, while hepatitis B, C, and D are mainly spread through blood and other body fluids. Treatment should be tailored according to the specific circumstances.

What are the indicators for viral hepatitis testing?

Viral hepatitis can be confirmed for infection through tests such as hepatitis B "two and a half pairs," hepatitis A antibodies, hepatitis C antibodies, and hepatitis E antibodies. By using the hepatitis B "two and a half pairs" test to look for the hepatitis B surface antigen, if the surface antigen is positive, it indicates infection with the hepatitis B virus. The hepatitis A antibody test primarily assesses for hepatitis A antibody IGM; if this is positive, it suggests an active infection. Through the hepatitis C antibody test, if positive, further testing for hepatitis C virus RNA can be conducted. The hepatitis E antibody test mainly looks at hepatitis E antibody IGM, and the interpretation should be based on the specific circumstances.

How is viral hepatitis transmitted?

Viral hepatitis comes in many types, with its main pathogens including hepatitis A, B, C, D, E, and others. Each type targets different transmission pathways; for example, hepatitis A and E are primarily transmitted via the digestive tract. They can spread through fecal-oral transmission, and ingesting contaminated food can lead to the dissemination of hepatitis A or E. For hepatitis B, the main transmission routes include mother-to-child transmission, blood and body fluid transmission, and close personal contact can also lead to the transmission of hepatitis B. As for hepatitis C, the primary transmission method is through transfusion of blood or blood products, and patients on dialysis are a high-risk group for hepatitis C infection.

Symptoms of viral hepatitis

The clinical symptoms of viral hepatitis are mainly related to liver function. Generally, there are no obvious symptoms when liver function is normal or mildly abnormal. However, when liver function becomes significantly abnormal, symptoms such as fatigue, aversion to oil, nausea, abdominal distension, and poor appetite may occur. Different types of viral hepatitis have different prognoses and severity of illness. Treatment should be tailored to the actual situation, including liver protection, enzyme reduction, and addressing the cause through comprehensive treatment.

Do you need a blood transfusion for viral hepatitis?

The treatment of viral hepatitis generally does not require blood transfusion. The primary treatment methods for viral hepatitis include ensuring plenty of rest, eating smaller and more frequent meals, and paying attention to diet. Additionally, medications that protect the liver, reduce enzyme levels, and alleviate jaundice can be used. For viral hepatitis caused by hepatitis B or C, formal antiviral treatment is also necessary. If liver damage is extremely severe, leading to liver failure and very high bilirubin levels, artificial liver treatment can be administered. Artificial liver treatment is of two types: one is plasma exchange, commonly referred to as a blood transfusion, and the other is protein adsorption; both of these methods are relatively effective.
