An investigation of broad-spectrum antibiotic-induced liver injury based on the FDA Adverse Event Reporting System and retrospective observational study

Abstract

Abstract Tazobactam/piperacillin and meropenem are commonly used as an empiric treatment in patients with severe bacterial infections. However, few studies have investigated the cause of tazobactam/piperacillin- or meropenem-induced liver injury in them. Our objective was to evaluate the association between tazobactam/piperacillin or meropenem and liver injury in the intensive care unit patients. We evaluated the expression profiles of antibiotics-induced liver injury using the US Food and Drug Administration Adverse Event Reporting System (FAERS) database. Further, in the retrospective observational study, data of patients who initiated tazobactam/piperacillin or meropenem in the intensive care unit were extracted. In FAERS database, male, age, the fourth-generation cephalosporin, carbapenem, β-lactam and β-lactamase inhibitor combination, and complication of sepsis were associated with liver injury (p < 0.001). In the retrospective observational study, multivariate logistic regression analyses indicated that the risk factors for liver injury included male (p = 0.046), administration period ≥ 7 days (p < 0.001), and alanine aminotransferase (p = 0.031). Not only administration period but also sex and alanine aminotransferase should be considered when clinicians conduct the monitoring of liver function in the patients receiving tazobactam/piperacillin or meropenem.
