Treatment
The acute form of the hepatitis D virus is more likely to disappear on its own in co-infection cases, when a person gets infected with hepatitis B and hepatitis D at the same time. Fewer than 5 percent of people co-infected will develop chronic hepatitis D.
In superinfection cases, in which a person with chronic hepatitis B then gets hepatitis D, up to 80 percent of people will develop chronic hepatitis D. These cases may result in severe chronic hepatitis D that often progress to cirrhosis (end-stage liver disease) or cancer of the liver.
The drug interferon may be helpful in treating disease conditions in some patients.
