Hepatitis E virus infection results in acute graft failure after liver transplantation: a case report
Hepatitis E virus (HEV) infection in most individuals is known as a self-limiting, acute, icteric hepatitis, but evidence shows HEV is responsible for choric hepatitis and rapid progressed liver cirrhosis in immuno-compromised patients. We present the case of a patient whose diagnosis of acute graft failure was due to a HEV infection 7 years after his first liver transplantation because of Wilson’s disease. The process showed severe jaundice with fatigue, poor appetite and continually rising serum aminopherase. The blood serum was found positive for the anti-HEV IgG antibody but negative for anti-HEV IgM or other infections. Cholangiole cholestasis was detected in graft biopsy. Triple hepato-protective drugs (Transmetil, Polyene Phosphatidylcholine, and Compound Ammonium Glycyrrhetate S) alongside five times Artificial Liver Support System (ALSS) did not improve the patient’s condition, but the total bilirubin level rose to more than 900umol/L. So re-transplantation was performed. Blood testing shows normal liver enzymes and bilirubin with persisting anti-HEV IgG antibody positive at the 3-month follow-up.
