High aminotransferase in kidney cancer patients is usually caused by the damage of liver function, which can be orally taken to protect liver and also take drugs to reduce aminotransferase. High aminotransferase in kidney cancer patients suggests that there is damage to liver cells, such as elevated alanine aminotransferase, the normal range of test value is 0-40 U/L. There are many reasons for it: 1. disorders of liver itself, especially all types of viral hepatitis, cirrhosis, liver abscess, liver tuberculosis, liver cancer, fatty liver, hepatomegaly, etc. 2. Myocarditis, pyelonephritis, lobar pneumonia, tuberculosis, encephalitis B, polymyositis, extrusion syndrome, etc., which can also be seen as elevation of blood transaminases. 3. Pharmacogenetic or toxic liver damage, as well as drug allergy can cause transaminase elevation, often accompanied by cholestatic jaundice and hepatocellular damage. Such as erythromycin, tetracycline, sleeping pills, antipyretic and analgesic drugs, contraceptive pills and so on. If the transaminase is elevated, the first thing to do is to identify the cause of the disease. If it is drug-related, it is recommended to stop using the desired drugs; if it is caused by other causes of transaminase elevation, it is necessary to actively treat the primary disease; in addition, according to the situation of the use of liver-protecting drugs, such as diammonium glycyrrhizinate, etc., can improve the transaminase, and the specifics need to be used according to the doctor’s instructions.
