Epidemiology of drug-induced liver injury in China

BACKGROUND: The epidemiology of drug-induced liver injury (DILI) in China has rarely been studied before. The aim of the present study was to determine the etiology of DILI in a Chinese population by reporting a systematic analysis of the Chinese literature published from 1994 to 2011. METHODS: A comprehensive database search of the Chinese literature was performed to obtain all the relevant studies. The data, including the drug names and patients' sex, age, clinical classification, and prognosis, were collected and analyzed. RESULTS: In this research, we found 279 studies including 24 112 patients. There were 265 studies that reported the sex of 21 789 patients, 11 787 men and 10 002 women. The therapeutics included (but were not limited to) tuberculostatics, complementary and alternative medicines (CAMs), antibiotics, NSAIDs, antineoplastics, central nervous system agents, antithyroid drugs, and immunomodulators. Of these drugs, tuberculostatics and CAMs were the most common etiologies of DILI in China. CONCLUSION: DILI in China has a different etiology from that in Europe and USA. NSAIDs, which are the most common causes of DILI in western populations, are uncommon in China. Therefore, government, physicians, and patients should pay more attention to these drugs in DILI.
