Evidence of hepatitis E virus transmission by renal graft.

Hepatitis E virus (HEV) can cause chronic infection among immunocompromised patients, especially solid organ transplant recipients, and can evolve to cirrhosis. Several modes of transmission are known. Here we describe the first two cases, to our knowledge, of HEV infection transmitted by a kidney graft from the same infected donor that led to chronic hepatitis. Consequently, systematic screening of donors by HEV serology and HEV RNA detection by polymerase chain reaction, particularly in endemic regions, should be considered.
