A case of late presentation of darunavir-related cholestatic hepatitis.

We report a case of darunavir-induced cholestatic hepatitis in a human immunodeficiency virus (HIV)-infected patient in the third year of his combined antiretroviral therapy. During the patient's monthly follow-up with regard to his HIV infection, elevated transaminase levels were detected. The patient was subsequently hospitalised at the AIDS and gastroenterology departments. All tested viral hepatitis markers were negative. A diagnosis of autoimmune hepatitis was also ruled out. The liver biopsy revealed cholestatic hepatitis. Darunavir withdrawal resulted in a progressive decrease in liver enzyme levels. We highlight the importance of recognising late development of liver injury secondary to the use of darunavir, and the importance of monitoring liver function in patients undergoing prolonged treatment involving darunavir.
