Delayed drug-induced liver injury (DILI) and flare of chronic plaque psoriasis secondary to lisinopril use.

Lisinopril is an ACE inhibitor commonly used in the treatment of cardiovascular and renal disease. Rarely, ACE inhibitors have been associated with cholestatic jaundice and hepatitis, with potential risk of fulminant hepatic failure if continued. There is limited information available regarding the risk of hepatic failure secondary to lisinopril use, with a handful of case reports demonstrating drug-induced liver injury at varying time scales from drug initiation. In this case, we present a man with symptoms of cholestatic jaundice, a blistering skin rash and flare of chronic plaque psoriasis, 27 months after lisinopril initiation for hypertension. Biochemical, serological and radiological investigations of an alternative cause for his jaundice were unremarkable. Cessation of lisinopril led to a rapid and sustained improvement in liver biochemistry and a significant improvement in his chronic plaque psoriasis.
