Adenosine deaminase is one of the liver function tests, which can be combined with glutamate aminotransferase and other related enzymes to form a liver enzyme profile, which can reflect the state of liver function more comprehensively. First of all, for patients with acute hepatitis, adenosine deaminase will be obviously elevated, at this time the patient needs to further blood test for hepatitis B DNA or hepatitis C RNA, to see whether the patient has replication of the virus. If the virus is replicating, and there is a combination of adenosine deaminase elevation, as well as glutamic acid transaminase elevation, glutamic acid transaminase elevation, it is necessary to actively consider the use of hepatoprotective therapy, and at the same time, to be given antiviral therapy. Oral lamivudine and entecavir can be considered, as well as interferon injection for further antiviral treatment. After 2-3 weeks of treatment, the patient should review the liver function to see if the patient’s liver function has improved. In addition, patients should pay attention to rest more in normal times, do not stay up late, do not be tired, and eat more food rich in vitamin C.
