Hepatitis E-induced severe myositis

Muscle Nerve. 2016 Feb;53(2):317-20. doi: 10.1002/mus.24959. Epub 2015 Nov 24.

Abstract

Introduction: Hepatitis E virus (HEV) is endemic in Asian and African countries but is rarely reported in Western countries. Although there are some prominent neurological manifestations, HEV is rarely recognized by neurologists.

Methods: This is a case report of myositis induced by HEV.

Results: We report the life-threatening case of a 57-year-old man with flaccid tetraparesis due to myositis, acute hepatitis, and renal failure caused by HEV infection. Muscle biopsy revealed scattered myofiber necrosis with a diffuse, mild lymphomonocytic infiltrate in the endomysium and perimysium. Because the patient suffered from an acute HEV infection with a rapidly progressive course of severe myopathy, we started ribavirin treatment. He recovered partially within 3 weeks and recovered fully within 6 months.

Conclusion: This case highlights a neurological manifestation of endemic HEV infection with severe myositis in a patient with alcoholic chronic liver disease. Ribavirin treatment is effective in severe HEV infection and may also lead to rapid neurological recovery.

Keywords: hepatitis E; myositis; neurological disorders in hepatitis E; rhabdomyolysis; ribavirin.
