'A case of autoimmune hepatitis associated with the PCSK9 inhibitor alirocumab'.

ABSTRACT

This is a case of a 61-year-old lady who presented to the lipid clinic with possible familial hypercholesterolaemia (Simon Broome Criteria). She was commenced on atorvastatin; however, 4 weeks later, she developed hepatitis, and therefore her atorvastatin was discontinued. Following that, her liver function tests normalized, and she was diagnosed with statin-induced hepatitis. Three years later, she was seen again in the lipid clinic with an uncontrolled lipid profile, and she was commenced on alirocumab, a Proprotein Convertase Subtilisin/Kexin type 9 (PCSK9) inhibitor. A few days later, she developed hepatitis, and subsequently, the alirocumab was discontinued. She underwent a liver biopsy, which confirmed that she had Autoimmune Hepatitis (AIH) with presumed superimposed drug injury. This is the first reported case of autoimmune hepatitis associated with alirocumab.
