Inflammation of the liver due to the hepatitis C virus (HCV), which is usually spread via blood transfusion (rare), hemodialysis, and needle sticks. The damage hepatitis C does to the liver can lead to cirrhosis and its complications as well as cancer. Transmission of the virus by sexual contact is rare. At least half of hepatitis C patients develop chronic hepatitis C infection. Diagnosis is made by blood test. Treatment and probably cure is via antiviral drugs and is effective in over 90% of patients. Chronic hepatitis C was frequently treated with injectable interferon, in combination with antiviral oral medications, but now is most often treated with oral antivirals alone. There is no vaccine for hepatitis C. Previously known as non-A, non-B hepatitis.
- PCR (polymerase chain reaction)
PCR (polymerase chain reaction) is a technique in molecular genetics that permits the analysis of any short sequence of DNA (or RNA) even in samples containing only minute quantities of DNA or RNA. PCR is used to reproduce (amplify) selected sections of DNA or RNA for analysis. Previously, amplification of DNA involved cloning the segments […]
- Hepatitis C virus
A single-stranded RNA virus in the Flaviviridae family that causes hepatitis C. Abbreviated HCV. The HCV genome contains some 10,000 nucleotides and encodes a single polyprotein of 3,000 amino acids. HCV was discovered in 1989. Before that time, hepatitis C was referred to as non-A, non-B hepatitis.
- Hepatitis D
Liver inflammation due to the hepatitis D virus (HDV), which causes disease only in patients who additionally have the hepatitis B virus. Transmission occurs via infected blood, needles, or sexual contact with an infected person. Symptoms are identical to those of hepatitis B. HDV infection can be prevented with the hepatitis B vaccine and through […]
- 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.
- Hepatitis E
A rare form of liver inflammation caused by infection with the hepatitis E virus (HEV). It is transmitted via food or drink handled by an infected person or through infected water supplies in areas where fecal matter may get into the water. Hepatitis E does not cause chronic liver disease. There is no vaccine or […]
