Autochthonous hepatitis E virus (HEV) is an emerging health issue in developed countries and is thought to be a porcine zoonosis; its spread is underestimated and there is concern about the possibility of chronic infection in immunosuppressed patients; HEV transmission through blood has also been demonstrated. We conducted a retrospective study (2007-2013) on HEV seroprevalence using stored serum samples from 132 blood donors and 118 renal transplant recipients living mainly in central Italy. Anti-HEV IgG was positive in 12/132 (9.1%) of the blood donors and 12/118 (10.2%) of the transplant recipients. All subjects but one were autochthonous and none showed signs of liver disease at the time of sampling. A significant association was documented between mean age of patients and the serology against HEV especially in the group of blood donors. Our study, albeit limited and retrospective, confirms the circulation of autochthonous HEV in central Italy; the presence of antibodies against HEV in particular categories of persons such as blood donors and transplant patients, who are not screened for the infection, raises questions in terms of transfusion safety and health protection of immunocompromised patients.
