We investigated the post-transfusion transmission of hepatitis E in a patient by molecularly confirming its presence, and characterized the viral kinetics of HEV in this case., Methods: A Japanese man underwent re-thoracotomy for hemostasis followed by platelet transfusion. After the transfusion, the blood donor was found to be HEV positive. The donated blood was re-examined and was found to contain HEV. Throughout the prospective follow up of the patient, we analyzed the viral kinetics, chronological anti-HEV antibody level changes and disease progression during the entire course of HEV infection from transfusion until the end of viremia., Results: Sequence analysis of the strains isolated from both the donor and the patient who contracted acute hepatitis E showed an identical match for 326 nucleotides in open reading frame 1. Two strains belonged to HEV genotype 3 indigenous to Japan., Conclusion: To the best of our knowledge, this is the first detailed report on the entire natural course of hepatitis E from viral transmission, then clearance, to replication preceding liver injury caused by HEV genotype 3, which is responsible for autochthonous infection in developed countries. The findings provide valuable insights into the mechanism of the transfusion transmission of HEV and subsequent viral dynamics., (C) 2015 John Wiley & Sons, Ltd M1 - 9711801 PB - (1)Center for Gastroenterology, Teine Keijinkai Hospital, Sapporo, Japan(2)Department of Virology, Nagoya City University Graduate School of Medical Sciences, Nagoya, Japan(3)Japanese Red Cross Hokkaido Block Blood Center, Hokkaido, Japan CY - (C) 2015 John Wiley & Sons, Ltd SN - 1386-6346 L2 - http://ovidsp.ovid.com/ovidweb.cgi?T=JS&PAGE=reference&D=ovftq&NEWS=N&AN=00066974-900000000-99882 ID - 4072 ER -
