Fascioliasis, a parasitic infection of liver caused by a liver fluke of the genus Fasciola, mostly Fasciola hepatica. [5] Hepatitis, inflammation of the liver, is caused by various viruses (viral hepatitis) also by some liver toxins (e.g. alcoholic hepatitis), autoimmunity (autoimmune hepatitis) or hereditary conditions. [6]
Hepatitis A causes an acute illness that does not progress to chronic liver disease. Therefore, the role of screening is to assess immune status in people who are at high risk of contracting the virus, as well as in people with known liver disease for whom hepatitis A infection could lead to liver failure.
Viral hepatitis is liver inflammation due to a viral infection. [1] [2] It may present in acute form as a recent infection with relatively rapid onset, or in chronic form, typically progressing from a long-lasting asymptomatic condition up to a decompensated hepatic disease and hepatocellular carcinoma (HCC).
Other preventive measures include hand washing and properly cooking food. [1] No specific treatment is available, with rest and medications for nausea or diarrhea recommended on an as-needed basis. [1] Infections usually resolve completely and without ongoing liver disease. [1] Treatment of acute liver failure, if it occurs, is with liver ...
A form of infection with persistently moderately elevated serum liver enzymes but without antibodies to hepatitis C has also been reported. [45] This form is known as cryptogenic occult infection. Several clinical pictures have been associated with this type of infection. [46]
The most frequent forms are metastatic malignant neoplasm of liver) liver cell carcinoma hepatocellular carcinoma; hepatoma; cholangiocarcinoma; hepatoblastoma; angiosarcoma of liver; Kupffer cell sarcoma; other sarcomas of liver; Benign neoplasm of liver include hepatic hemangiomas, hepatic adenomas, and focal nodular hyperplasia (FNH).
Another 1.5 million developed acute infections that year, and 820,000 deaths occurred as a result of HBV. [1] Cirrhosis and liver cancer are responsible for most HBV-related deaths. [ 18 ] The disease is most prevalent in Africa (affecting 7.5% of the continent's population) and in the Western Pacific region (5.9%). [ 19 ]
Hepatitis E is inflammation of the liver caused by infection with the hepatitis E virus (HEV); [4] [5] it is a type of viral hepatitis. [6] Hepatitis E has mainly a fecal-oral transmission route that is similar to hepatitis A, although the viruses are unrelated.
