The enzyme alanine aminotransferase (ALT) is present in liver cells, and when the liver is damaged, the necrosis of liver cells ALT is released into the blood resulting in ALT elevation. Causes of ALT elevation include viral hepatitis, etc., which need to be treated symptomatically, and at the same time can be treated routinely with hepatoprotective enzyme drugs, and if caused by viral hepatitis, antiviral treatment is needed. 1. Symptomatic treatment: ALT elevation caused by hepatic necrosis due to liver inflammatory injury can be treated with hepatoprotective enzyme drugs, such as polyunsaturated phosphatidylcholine capsule, which can help to improve the recovery of serum ALT due to toxic liver injury, but may cause gastrointestinal disorders, allergies and other adverse reactions, and is contraindicated for those who are allergic to soybean preparations and phosphatidylcholine. 2. Anti-causal treatment: ALT elevation caused by virus-induced hepatocellular necrosis requires antiviral treatment, such as entecavir, which can interfere with viral DNA polymerase, inhibit viral replication, reduce hepatocellular damage, and restore the concentration of ALT, but it may cause itching, urticaria, coma, hallucinations, and other adverse reactions, and is contraindicated for those who are allergic to allergies, with abnormalities of hepatic and renal functions, and pregnant women. In addition if malnutrition, excessive exercise caused by, etc. can also cause ALT elevation, need to pay attention to rest, supplemental nutrition, regular review. If ALT is found to be elevated, it is recommended to go to the hospital for consultation and prompt treatment after clarifying the cause of the disease.
