Key messages on HEV

• First cause of acute hepatitis worldwide

• Emerging autochtonous infectious disease

• HEV should always be searched in the setting of

acute/chronic unexplained liver disease

• Use PCR

• Ribavirin is a treatment of HEV

• Extrahepatic replication of HEV accounts for

extrahepatic diseases, including

lymphoproliferative disorders

Recommendations

• Compromised patients should be informed about

the risks of foodborne transmission of HEV (A III)

• For patients with chronic HEV, reduction of

immunosuppressive drugs could be considered

(B III)

• For patients with chronic HEV, antiviral therapy

with ribavirin could be considered (B III) Mallet V, et al.
