Hepatic Relating to the liver
Hepatic failure Liver failure, (severe) impairment of liver function due to a liver disease. Hepatic failure can be acute, fulminant or subfulminant - or chronic.
Hepatic hydrothorax Pleural effusion in a patient with liver cirrhosis (and most often ascites). Hepatic hydrothorax is a rare but severe finding, as it indicates end stage liver disease, where liver transplantation should be considered.
Hepatitis Inflammation in the liver, due to viral infection, drugs or alchohol.
Hepatitis A A viral acute hepatitis caused by the Hepatitis A virus, belonging till the Picornaviridae-family. The transmission route is faecal-oral. The disease is usually selflimiting, it very seldomly becomes fulminant and never goes into a chronic state. There is no treatment, but the disease can be prevented by good hygien. A vaccine from killed virus is available and effective.
Hepatitis B A viral hepatitis caused by the Hepatitis B-virus, a Orthohepadnavirus. The transmission route is parenteral. A fulminant course is uncommon, but the infection is often chronic causing liver cirrhosis and an elevated risk of liver cancer. B-hepatitis can be treated by Lamivudin and in some cases by Interferon. The disease can be prevented by vaccination.
Hepatitis C A viral hepatitis caused by the Hepatitis C-virus, a Flaviviridae-virus. The transmission route is parenteral. A fulminant course is rare but the disease is very often chronic, causing liver cirrhosis and an elevated risk of liver cancer. The disease can easily be avoided by avoiding blood contact with infected people (for example dirty needles). No vaccine is available against Hepatitis C.
Hepatitis D A viral hepatitis caused by the Deltavirus. The transmission route is parenteral, and this hepatitis affect only patients who already have B-hepatitis. A fulminant course is common, and the course of this disease is usually chronic, causing an elevated risk of liver cancer. Interferon may be partly effective in some patients.
Hepatitis E A viral hepatitis, mostly affecting people in developing countries, and especially dangerous when affecting pregnant women, where the course often is fulminant.
Hepatitis F A viral hepatitis described by Deca in 1994. The existence of this disease has not been proved later and the Hepatitis F virus described is probably a non-pathogenic virus.
Hepatitis G A viral hepatitis described in 1996. The nature and significance of this viral hepatitis is still under investigation
Hepatitis GB A viral hepatitis caused by the GB-virus-C, probably the same disease as Hepatitis G
Hepato- (Pre) Liver-
Hepatocellular Carcinoma Liver cancer, one of the most common malignancies in the world, especially in countries where chronic B-hepatitis is common. Cirrhosis due to chronic hepatitis (B- or C-hepatitis), hemochromatosis or alchohol abuse is the main etiologic factor. HCC is a serious disease, where radical surgical treatment is the only curative treatment.
Hepatogenital syndrome A rare syndrome chararcterized by a premature puberty due to a hormonproducing liver tumor.
Hepatolenticular degeneration Another name for Wilson´s disease. See Wilson´s disease.
Hepatomegaly Enlarged, too large liver
Hepatopulmonary syndrome A syndrome occuring in patients with chronic liver diseases, where the typical findings are vascular dilations in the lungs and impaired oxygenation. Dyspnea is the common symptom, nail clubbing and cyanosis being the common findings. One year after liver transplantation most of the patients are quite symptomfree. A beneficial effect of garlic has been suggested.
Hepatorenal syndrome A severe complication of liver cirrhosis or other severe liver diseases. The typical features of hepatorenal syndrome is renal dysfunction caused by abnormalities in the arterial circulation and the vasoactive systems, resulting in renal vasoconstriction and renal insufficiency. Hepatorenal syndrome can be divided into two types, in type I the renal function is rapidly reduced, in type II the renal failure does not progress rapidly.
Hepatotesticular syndrome Hypofunction of the testes in a patient with liver cirrhosis
Hepsera (RTM) An antiviral drug containing adefovir dipivoxil, used in the treatment of Hepatitis B.
Hereditary Nonpolyposis Colorectal Cancer (HNPCC) is a hereditary syndrome characterized by a very high risk of colorectal cancer and an increased risk of other cancers, especially endometrial cancer. The risk of colorectal cancer is over 80% and regular screening for cancer is obligatory in patients that hav this identifiable genetic syndomre.
Herter, Christian Archibald (1865 - 1910) An American Internist working in New York and known for his investigations concerning the disease now known as coeliac disease.
