- Although herbal medicines (HMs) are widely used in Asian and Western countries, medicinal information concerning their hepatic toxicity or interaction with conventional medicines (CMs) is sparse.The aim of our study was to estimate the prevalence of drug-induced liver injury (DILI) among total inpatients prescribed HMs or CMs. Furthermore, we noted all medications suspected to be associated with hepatotoxicity in the liver injury group during the period of hospitalization.We retrospectively observed medical records of 1169 inpatients in a single medical center from January 2012 to July 2014.Based on a database of the 1169 inpatients at a single medical center, we researched the occurrence rate and type of liver injury according to the criteria of the Council for International Organization of Medical Science (CIOMS). We also utilized a simplified Roussel Uclaf Causality Assessment Method (RUCAM) score for probable causality assessment between drugs and liver injury.Among a total of 1169 inpatients, 13 cases whose baseline LFTs had been in the normal range at admission had abnormal liver parameters at the time of follow-up, and 11 of them (0.94%) were attributed to drugs: 0.43% (5 of 1169) to HMs, 0.43% (5 of 1169) to CMs, and 0.09% (1 of 1169) to combined drug classes. Two of them were found to have liver injury because of pneumonia and sepsis. As for liver injury type, 8 cases were hepatocellular, 2 were cholestatic, and 1 was of mixed pattern. The common causative HMs for hepatotoxicity were Ephedrae Herba and Scutellariae Radix, while CMs included antidepressants, antihistamines, and antibacterials.We investigated approximate incidence rates and analyzed suspicious drugs associated with liver damage, which revealed a low frequency of liver injury induced by HMs. However, further study, based on a well-designed, long-term, multicenter prospective study, will be required to determine the safety of HMs.
