Abstract

SANCHEZ-AZOFRA, María et al. Hepatitis E virus in neurological disorders: a case of Parsonage-Turner syndrome. Rev. esp. enferm. dig. [online]. 2018, vol.110, n.6, pp.402-403. ISSN 1130-0108.  https://dx.doi.org/10.17235/reed.2018.5506/2018.

Hepatitis E virus (HEV) infection is an emerging disease in developed countries with a broad clinical spectrum. In the absence of immunodeficiency or pregnancy, it is a mild and almost asymptomatic condition in most cases. However, extrahepatic manifestations, including neurological conditions, are common and may occasionally lead to permanent neurological sequelae.

Herein, we report the case of an immunocompetent patient who was admitted to our hospital with paresthesia and weakness in both the upper extremities associated with anicteric-elevated transaminases. The diagnosis was Parsonage-Turner syndrome (neuralgic amyotrophy) secondary to HEV infection. The diagnosis was reached via electromyography and serology tests. Neuralgic amyotrophy (NA) is a demyelinating axonal disease that affects the brachial plexus and is associated with HEV infection in up to 10% of cases.

We also emphasize the importance of requesting HEV serology in patients with neurological disease, especially with the involvement of the peripheral nervous system. Although the role of ribavirin remains to be fully determined, early diagnosis and treatment may result in an improved prognosis, thereby minimizing neurological sequelae.

Keywords : Hepatitis E; Nervous system diseases; Brachial plexus neuritis; Parsonage-Turner syndrome.
