Actuele dilemma’s rond de transmissie van hepatitis E-virus

Immunocompromised patients are especially at risk for developing chronic hepatitis E virus (HEV) infection, which may result in progressive liver disease and cirrhosis. In addition, treatment of chronic HEV infection in these patients often includes dose reduction of immunosuppressive therapy and this may lead to severe flare-ups of the underlying condition or even rejection of transplant material. Therefore prevention of HEV transmission is being more and more recognised as an essential step to stop increasing HEV seroprevalence. The Dutch National Institute for Public Health and the Environment (RIVM) has recently warned immunocompromised patients following haematopoietic stem cell and solid organ transplantations for the risk of infection by HEV through eating of contaminated products from pig meat. Furthermore, the Dutch blood bank recently decided to start screening all blood products for HEV to prevent iatrogenic transmission of HEV. We describe two patients with HEV infection and discuss risk of infection for immunocompromised patients, transmission routes and the importance of prevention of iatrogenic transfusion related transmission.
