RT Journal Article SR Electronic T1 Meropenem-induced liver injury and beta-lactam cross-reactivity JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e227124 DO 10.1136/bcr-2018-227124 VO 11 IS 1 A1 Timothy Tattersall A1 Hugh Wright A1 Andrew Redmond YR 2018 UL http://casereports.bmj.com/content/11/1/e227124.abstract AB A 63-year-old man admitted to hospital for the management of a frontal lobe abscess developed elevated liver enzymes within 48 hours of receiving meropenem. Liver enzymes reached a maximum at 5 days postadministration of meropenem, with alanine aminotransferase 1160 U/L, aspartate aminotransferase 787 U/L, alkaline phosphatase 297 U/L and gamma-glutamyltransferase 252 U/L. Meropenem was ceased and liver function normalised. Meropenem was administered for a second time later in the patient’s admission and again the patient developed rapidly increasing liver enzymes, with a mixed hepatocellular/cholestatic pattern. Other possible causes of liver injury were excluded following extensive investigations, and the patient’s liver enzymes continued to normalise following meropenem discontinuation. The patient was asymptomatic during the admission and was transferred to a rehabilitation facility. This case demonstrates that meropenem can cause severe liver injury and that early recognition of drug-induced liver injury is important.
