Hepatitis E virus (HEV) infection is known to run a self-limiting course. Sporadic cases of acute hepatitis due to infection with HEV genotype 3, present in pig populations, are increasingly recognized. Zoonotic transmission seems infrequent. ⋯ Genotyping in both cases revealed 2 unique strains of genotype 3. In conclusion, chronic HEV infection may develop in immunosuppressed patients, who may then serve as long-term carriers of the virus. We hypothesize that HEV may be the cause of chronic hepatitis in liver transplant recipients.

The greatest part of liver allograft injury occurs during reperfusion, not during the cold ischemia phase. The aim of this study, therefore, was to investigate how the severity of postreperfusion syndrome (PRS) influences short-term outcome for the patient and for the liver allograft. Over a 2-year period, 338 consecutive patients who presented for orthotopic liver transplantation (OLT) were included in this retrospective study. ⋯ Group 2 also required longer, on average, mechanical ventilation (14.95 +/- 29.79 versus 8.55 +/- 17.79 days, P = 0.015), remained in the intensive care unit longer (17.65 +/- 31.00 versus 11.49 +/- 18.67 days, P = 0.025), and had a longer hospital stay (27.29 +/- 32.35 versus 20.85 +/- 21.08 days, P = 0.029). Group 2 was more likely to require retransplantation (8.6% versus 3.3%, P = 0.044). In conclusion, the severity of PRS during OLT appears to be related to the outcome of patient and liver allograft.
