Mining and analysis for adverse drug event signals of liver failure in underage population based on the FAERS database / 中国药房

ABSTRACT

OBJECTIVE To conduct data mining on drugs causing liver failure in underage populations based on the FDA Adverse Event Reporting System （FAERS） database， so as to provide reference for clinical use of related drugs. METHODS The data on reported adverse drug event （ADE） of liver failure in this population （under 18 years old） from the first quarter of 2013 to the third quarter of 2022 were retrieved from the FAERS database for mining and analysis； they were divided into infants（≤1 year old）， young children（＞1-＜6 years old）， children（6-＜12 years old） and adolescents（12-＜18 years old） according to the age. The reporting odds ratio （ROR）， proportional reporting ratio and Bayesian confidence propagation neural network of the proportional imbalance method were used to screen ADE signals. RESULTS A total of 1 051 ADE reports of liver failure were collected from the underage population involving 60 drugs. The highest incidence was found in adolescents （410 cases， 39.01%）， followed by young children （297 cases， 28.26%）. The instructions of 14 drugs did not mention hepatobiliary system injury and liver failure risk， including 31 cases of levetiracetam （2.95%），18 cases of metronidazole （1.71%）， 16 cases of each of topiramate and methylprednisolone （1.52% each）， 12 cases of dexamethasone （1.14%）， 11 cases of tisagenlecleucel （1.05%）， 10 cases of each of ferrous sulfate， metformin and busulfan （0.95% each）， 9 cases of propofol （0.86%）， 8 cases of onasemnogene abeparvovec （0.76%）， 5 cases of each of diphenhydramine and omeprazole （0.48% each）， 4 cases of sebeliesterase α （0.38%）， totaling 165 cases， accounting for 15.70% of the total reported cases. Metformin was contrary to the known liver safety， and E-mail：libingchemical@163.com metronidazole and levetiracetam were new risk signals， which caused more serious clinical outcomes. CONCLUSIONS Fourteen new pharmacovigilance signals which cause liver failure in the underage population are found in this study； the liver function of patients should be closely monitored when using these drugs. Among those drugs， metformin neither undergoes liver metabolism nor has been reported in the relevant literature， and the liver-related ADE caused by metformin deserves further attention. The clinical outcomes caused by metronidazole and levetiracetam are relatively serious and need to be given sufficient attention.
