Hepatitis E virus and Bell's palsy.

Background And Purpose: Acute hepatitis E virus (HEV) infections have been associated with various neurological disorders, including individual cases with Bell's palsy. Nonetheless, systematic studies in the latter are lacking. Therefore, this retrospective study systematically screened a cohort of patients with Bell's palsy for an acute HEV infection.

Hepatitis E virus as a trigger for Guillain-Barré syndrome.

Background: Hepatitis E virus (HEV) is the most common cause of acute viral hepatitis worldwide. An association with neuralgic amyotrophy and Guillain-Barré syndrome (GBS) was previously described. Concerning GBS, studies from other countries found an acute HEV infection in 5-11% of cases.

Acute CNS infections - Expanding the spectrum of neurological manifestations of hepatitis E virus?

Background: Central nervous system (CNS) infections can be caused by a variety of viruses, but in a significant number of patients no viral or other pathogen can be identified using routine diagnostic work-up. Interestingly, several case reports and series described Hepatitis E virus (HEV) as a potential pathogen. However, systematic studies have not been conducted so far.
