    ABSTRACT: Hepatitis E virus (HEV) is a small, single-stranded, non-enveloped RNA virus and belongs to the genus Hepevirus in the Hepeviridae family. Currently, the HEV infection is the most frequent cause of acute hepatitis in the world. In recent years, some studies have been demonstrated that immunosuppressed cases, such organ transplant recipients, cases with HIV infection and patients with hematological malignancies are at risk of HEV infection. But it is not clear whether HEV infection is a major concern in HIV infected patients or not? The answer has considerable significance, because HIV and HEV infection are now both highly endemic in many parts of the world. The purpose of this review is to provide data on the prevalence of HEV infection in HIV infected patients for determination of the significance of HEV/HIV co-infection.

    ABSTRACT: Mysterious aspects of the long presumed to be well-known hepatitis E virus (HEV) have recently surfaced that distinguish it from other hepatotropic viruses. It is a cause of chronic hepatitis in immunosuppressed patients. It has human to human transmission through blood and mantains high seroprevalence in blood donors. HEV has also been found to occur more frequently in the West in those without a history of travel to endemic countries. It has varied extrahepatic manifestations and has multiple non-human reservoirs including pigs and rats. Considering these recent discoveries, it appears odd that HEV is not sought more frequently when working up acute and chronic hepatitis patients. The disease is particularly severe among pregnant women and has a high attack rate in young adults. What adds to its ambiguity is the absence of a well-established diagnostic criteria for its detection and that there is no specific antiviral drug for hepatitis E, except for isolated cases where ribavirin or pegylated interferon alpha has been used with occasional success. This review paper discusses the recent advances in the knowledge of the virus itself, its epidemiology, diagnostic approach and prevention, and the treatment options available.
