| HAV | Hepatitis A Virus |
| viral hepatitis type B | A virus disease with a long incubation period (usually 50 to 160 days), caused by hepatitis B virus, a DNA virus and member of the family Hepadnoviridae, usually transmitted by injection of infected blood or blood derivatives or by use of contaminated needles, lancets, or other instruments; clinically and pathologically similar to viral hepatitis type A, but there is no cross-protective immunity; HBsAg is found in the serum and the hepatitis delta virus occurs in some patients. Synonym: hepatitis B, serum hepatitis, transfusion hepatitis, virus B hepatitis. (05 Mar 2000) |
|---|---|
| viral hepatitis type C | Principal cause of non-A, non-B posttransfusion hepatitis caused by an RNA virus that may be related to Flaviviridae family. Synonym: hepatitis C, virus C hepatitis. (05 Mar 2000) |
| viral hepatitis type D | Acute or chronic hepatitis caused by the hepatitis delta virus, a defective RNA virus requiring HBV for replication. The acute type occurs in two forms: 1) coinfection, the simultaneous occurrence of hepatitis B virus and hepatitis delta virus infections, which usually is self-limiting; 2) superinfection, the appearance of hepatitis delta virus infection in a hepatitis B virus carrier, which often leads to chronic hepatitis The chronic type appears to be more severe than other types of viral hepatitis. Synonym: delta hepatitis, hepatitis D. (05 Mar 2000) |
| viral hepatitis type E | Hepatitis caused by a nonenveloped, single-stranded, positive-sense RNA virus 27-34 nm in diameter, unrelated to other hepatitis; it is the principal cause of enterically transmitted, waterborne, epidemic NANB hepatitis occurring primarily in Asia and Africa. Synonym: hepatitis E. (05 Mar 2000) |
| viral hepatitis vaccines | Any vaccine raised against any virus or viral derivative that causes hepatitis. (12 Dec 1998) |
| peliosis hepatitis | A rare condition in which the liver contains very numerous small blood-filled spaces, sometimes lined with endothelium; it may be found incidentally or rupture may cause intraperitoneal haemorrhage. (05 Mar 2000) |
| goose viral hepatitis | An acute, highly fatal disease of goslings and Muscovy ducklings caused by the goose parvovirus and characterised by anorexia, feather loss, and tissue haemorrhages. Synonym: Derzsy's disease. (05 Mar 2000) |
| persistent chronic hepatitis | A benign chronic hepatitis that may follow acute viral hepatitis A or B, or complicate bowel diseases; after six months, liver biopsy changes are mild, unlike active chronic hepatitis; rarely, if ever, progresses to cirrhosis, portal hypertension, or liver failure. (05 Mar 2000) |
| cholangiolitic hepatitis | Hepatitis with inflammatory changes around small bile ducts, producing mainly obstructive jaundice; may be due to viral infection or bacterial infection ascending biliary tree because of obstruction. (05 Mar 2000) |
| cholestatic hepatitis | Jaundice with bile stasis in inflamed intrahepatic bile ducts; usually due to toxic effects of a drug. (05 Mar 2000) |
| chronic active hepatitis | <pathology> This is a form of continuing liver inflammation that results in liver cell death. Causes include viral infection (hepatitis D, hepatitis B, hepatitis C), autoimmune disease, drug ingestion or metabolic causes. Chronic active hepatitis will lead to hepatic failure and death in a small percentage of these patients. (27 Sep 1997) |
| chronic hepatitis | Any of several types of hepatitis persisting for more than six months, often progressing to cirrhosis. Synonym: chronic active liver disease. (05 Mar 2000) |
| chronic interstitial hepatitis | An obsolete term for cirrhosis of the liver. (05 Mar 2000) |
| chronic persistent hepatitis | <pathology> A form of hepatitis usually caused by hepatitis C or B, that consists of mild persistent liver inflammation. Often a mild elevation of the liver enzymes will be seen on liver profile or SMAC 25 assay. Liver biopsy indicates persistent hepatitis. Incidence: 1 in 1,000. (02 Jan 1998) |
| chronic persisting hepatitis | A form of chronic hepatitis that is usually benign, not progressing to cirrhosis, and usually asymptomatic without physical findings but with continuing abnormalities of tests of liver status. Synonym: chronic persistent hepatitis. (05 Mar 2000) |
