| hepatitis C | <virology> A form of viral hepatitis, previously referred to as nonA nonB hepatitis, is the most common form of blood transfusion acquired hepatitis. Transmission through sexual contact is considered rare. Risk factors include recent blood transfusion, IV drug abuse or occupational exposure to blood products. There is no specific treatment. There is a test for hepatitis C antibody which indicates prior exposure. Unlike hepatitis b there is no marker yet identifiable for those who suffer from chronic hepatitis C. (27 Sep 1997) |
|---|---|
| hepatitis c antibodies | Antibodies to the hepatitis c antigens including antibodies to envelope, core, and non-structural proteins. (12 Dec 1998) |
| hepatitis c antigens | Antigens of the virions of hepatitis c-like viruses, their surface, core, or other associated antigens. (12 Dec 1998) |
| hepatitis c, chronic | An inflammatory disease of the liver caused by hepatitis c virus lasting six months or more. (12 Dec 1998) |
| hepatitis, chronic | A collective term for a clinical and pathological syndrome which has several causes and is characterised by varying degrees of hepatocellular necrosis and inflammation. Specific forms of chronic hepatitis include autoimmune hepatitis (hepatitis, autoimmune), chronic hepatitis b (hepatitis b, chronic), chronic hepatitis c (hepatitis c, chronic), chronic hepatitis d (hepatitis d, chronic), indeterminate chronic viral hepatitis, cryptogenic chronic hepatitis and drug-related chronic hepatitis (hepatitis, chronic, drug-induced). (12 Dec 1998) |
| hepatitis, chronic, drug-induced | An inflammatory disease of the liver, lasting six months or more, and caused by an adverse drug effect. The adverse effect may result from a direct toxic effect of a drug or metabolite, or an idiosyncratic response to a drug or metabolite. The clinical and histological changes can mimic viral or autoimmune hepatitis. (12 Dec 1998) |
| hepatitis c-like viruses | A genus of flaviviridae causing parenterally-transmitted non-a, non-b hepatitis (hepatitis c) which is associated with transfusions and drug abuse. Hepatitis c virus is the type species. (12 Dec 1998) |
| hepatitis contagiosa canis | A disease of dogs, caused by canine adenovirus 1, and characterised by fever, depression, loss of appetite, vomiting, bloody diarrhoea, petechial haemorrhages in the gums, pale mucous membranes, and jaundice. Synonym: hepatitis contagiosa canis, Rubarth's disease. (05 Mar 2000) |
| hepatitis C virus | A non-A, non-B RNA virus causing post-transfusion hepatitis; it appears to be a member of the family Flaviviridae. (05 Mar 2000) |
| hepatitis D | <virology> A rare form of viral transfusion hepatitis. A defective viral agent that occurs only in association with hepatitis B infection. The delta agent may also increase the severity of hepatitis B infection. Complications include chronic persistent hepatitis and fulminant hepatitis. A test known as anti-delta agent antibody is positive and used to confirm the diagnosis. Treatment is the same as for hepatitis B. (27 Sep 1997) |
| hepatitis d, chronic | Inflammatory disease of the liver caused by hepatitis d virus in conjunction with hepatitis b virus and lasting six months or more. (12 Dec 1998) |
| hepatitis d, e, f, and g | Lesser known (than hepatitis a, b, and c), the most significant of these seems to be type d, or the delta agent, which only causes disease in the presence of the hepatitis b virus. (12 Dec 1998) |
| hepatitis delta | <virology> Hepatitis delta is a severe form of hepatitis which arose recently. It is caused by a combination of the delta virus (a defective virus) and the virus which causes hepatitis B. (09 Oct 1997) |
| hepatitis delta virus | A defective virus, containing particles of RNA nucleoprotein in virion-like form, present in patients with acute hepatitis b and chronic hepatitis. Officially this is classified as a subviral satellite RNA (RNA, satellite). (12 Dec 1998) |
| hepatitis D virus | A small "defective" RNA virus, similar to viroids and virusoids, that requires the presence of hepatitis B virus for replication. The clinical course is variable but is usually more severe than other hepatitides. Synonym: hepatitis delta virus. (05 Mar 2000) |
