Objective To explore the causes and characteristics of drug-induced liver injury (DILI) caused by proprietary Chinesemedicines, in order to standardize the use of proprietary Chinese medicines and reduce the adverse reactions related to proprietary Chi-nese medicines.Methods The medical records of the 159 confirmed cases of DILI caused by proprietary Chinese medicines in Su-zhou Hospital of Integrated Traditional Chinese and Western Medicine from January 2015 to December 2022 were reviewed, and thebasic situation of patients, primary diseases, drug history, clinical features, laboratory test results were recorded.Results The occur- rence of DILI caused by proprietary Chinese medicines was related to the age distribution of patients and underlying diseases, but notto gender; There were a total of 16 kinds of proprietary Chinese medicines involved, which were mainly used to treat gynecological andbreast diseases, skin diseases, osteoarthrosis, cardiovascular and cerebrovascular diseases and kidney diseases. Thirty-one patients with drug-induced liver damage were caused by Gukang Jiaonang, accounting for 19.50%, followed by Xianlin Gubao Jiaonang, ac- counting for 11.95%, Jiegu Qili Pian ranked the third (18 cases, 11.32%). Patients with orthopaedic diseases take the relevant proprie-tary Chinese medicines for a longer period of time. The 159 confirmed patients covered the three types of DILI, including hepatocellu-lar injury (76 cases, 47.80%), mixed type (51 cases, 32.08%), and cholestatic type (32 cases, 20.13%). Among them, patients with hepa-tocellular liver injury accounted for the highest proportion. In addition, more than half of patients had moderate liver injury (81 cases,50.94%).Conclusion Under the guidance of Chinese medicine theory, strictly following the treatment principles of TCM differentia-tion and treatment, and scientifically and standardizing the application of Chinese medicine are important measures to improve the safe-ty of medication and reduce drug-induced liver injury caused by proprietary Chinese medicine. |
