Hepatitis


Hepatitis (plural: hepatitides) is a medical condition defined by the inflammation of the liver and characterized by the presence of inflammatory cells in the tissue of the organ. Hepatitis may occur with limited or no symptoms, but often leads to jaundice (a yellow discoloration of the skin, mucous membrane, and conjunctiva), poor appetite, and malaise. Hepatitis is acute when it lasts less than six months and chronic when it persists longer.
Acute hepatitis can be self-limiting (healing on its own), can progress to chronic hepatitis, or, rarely, can cause acute liver failure.〔Bernal, W. and J. Wendon (2013). "Acute Liver Failure." New England Journal of Medicine 369(26): 2525-2534.〕 Chronic hepatitis may have no symptoms, or may progress over time to fibrosis (scarring of the liver) and cirrhosis (chronic liver failure).〔Dienstag JL. Chapter 306. Chronic Hepatitis. In: Longo DL, Fauci AS, Kasper DL, Hauser SL, Jameson J, Loscalzo J. eds. 'Harrison's Principles of Internal Medicine, 18e''.'' New York, NY: McGraw-Hill; 2012. http://accessmedicine.mhmedical.com/content.aspx?bookid=331&Sectionid=40727101. Accessed May 09, 2015.〕 Cirrhosis of the liver increases the risk of developing hepatocellular carcinoma (a form of liver cancer).〔Carr BI. Chapter 92. Tumors of the Liver and Biliary Tree. In: Longo DL, Fauci AS, Kasper DL, Hauser SL, Jameson J, Loscalzo J. eds. 'Harrison's Principles of Internal Medicine, 18e''.'' New York, NY: McGraw-Hill; 2012. http://accessmedicine.mhmedical.com/content.aspx?bookid=331&Sectionid=40726828. Accessed May 09, 2015.〕

Worldwide, viral hepatitis is the most common cause of liver inflammation.〔WHO Health Topics: Hepatitis ()
〕 Other causes include autoimmune diseases and ingestion of toxic substances (notably alcohol), nonalcoholic fatty liver disease, certain medications (such as paracetamol), some industrial organic solvents, and plants.

The term is derived from the Greek ''hêpar'' (), meaning "liver", and the suffix ''-itis'' (), meaning "inflammation" (c. 1727).〔(【引用サイトリンク】title=Online Etymology Dictionary )
