Fulminant Hepatic Failure Secondary to Herpes Hepatitis in a Patient With Myasthenia Crisis: An Elusive Diagnosis

Abstract

Herpes hepatitis is a rare cause of fulminant hepatic failure contributing to less than 1% of all cases. It is most often seen in persons who are immunosuppressed and in pregnant women. The presentation is usually non-specific and rapidly progressive, thus making antemortem diagnosis of this condition rare. We present a patient who was on chronic immunosuppressive therapy for systemic lupus erythematosus and subsequently developed multi-organ failure with anicteric transaminitis as a result of disseminated herpes infection. The diagnosis was only made post-mortem. A confounding factor in this case was the fact that the patient underwent plasmapheresis, which skewed the interpretation of liver function tests in the setting of acute liver failure.
