Liver Function Tests. A number of blood tests can be performed to determine how well a person's liver is functioning, and these results can aid in diagnosing hepatitis B infection. Until recently, delta hepatitis could be diagnosed only by liver biopsy in which a tiny piece of the liver is removed and examined. The test identifies antibody to HCV, which is present in more than 50 percent of persons with acute hepatitis C and in almost all with chronic hepatitis. At present, there are no specific treatments for the acute symptoms of viral hepatitis.
Doctors recommend bed rest, a healthy diet, and avoidance of alcoholic beverages.
A genetically engineered form of a naturally occurring protein, interferon alpha, is used to treat people with chronic hepatitis C. NIH-supported studies led to the approval of interferon alpha for the treatment of those with chronic HBV as well. The drug improves liver function in some people with hepatitis and diminishes symptoms, although it may cause side effects such as headache, fever, and other flu-like symptoms. Some patients do not respond to interferon alpha, and in others its beneficial effects lessen over time. Scientists are evaluating a number of experimental therapies that may be more effective and less toxic. Most patients with mild to severe acute hepatitis begin to feel better in 2 to 3 weeks and recover completely within 4 to 8 weeks.
