Acute hepatitis E in industrialized countries is usually related to intake or manipulation of undercooked or raw meat. Cases of transfusion-transmitted hepatitis E have rarely been documented in immunosuppressed patients, mainly after receiving frozen plasma.
A 61-year-old man was admitted to hospital for jaundice. His personal history included disseminated bacillus Calmette-Guerin infection treated with antituberculous drugs. He had received red blood cell (RBC) transfusion 2 months previously, during admission for mycotic aneurysm surgery. Since liver function tests worsened despite stopping antituberculous drugs, other causes of acute hepatitis were explored.
Acute hepatitis E was diagnosed by the presence of both immunoglobulin M and hepatitis E virus (HEV) RNA. Traceback procedure for the 8 RBC units was carried out, and one of the eight archive plasma samples tested positive for HEV RNA, with an estimated viral load of 75,000 IU/mL. Phylogenetic analysis revealed the same HEV strain Genotype 3 in one of the transfused RBC products and in the patient's serum sample.
Transfusion of RBCs with detectable HEV RNA is a risk factor for acute hepatitis E in immunocompetent patients in Europe.
