The clinical courses of two deceased patients with fulminant hepatitis. Case 1: A 41-year-old man with acute fulminant hepatitis related to the hepatitis B virus. Plasma exchange and CHDF were performed and PSL was administered. But hepatic encephalopathy progressed to a more severe stage and the pulsatility index was elevated to >1.00. The patient died on the 10th day. Case 2: A 47-year-old woman with subacute fulminant hepatitis due to unknown etiology. Her condition was accompanied by encephalopathy 1 month after liver dysfunction. She received plasma exchange but liver function gradually deteriorated and ascites developed. The pulsatility index was elevated to >1.00, and she died 2 months later. HE, Hepatic encephalopathy; PSL, predonisolone; CHDF, continuous hemodiafiltration.

The clinical courses of surviving patients with fulminant hepatitis. Case 3: A 22-year-old woman with acute fulminant hepatitis related to the hepatitis B virus. Plasma exchange and CHDF were performed for acute liver failure. In spite of the progression of HE, the pulsatility index was under 1.00 and she recovered. Case 4: A 56-year-old man with acute fulminant hepatitis related to the hepatitis B virus. In spite of plasma exchange, hepatic encephalopathy progressed. The pulsatility index was <1.00 on the third day. Liver transplantation was successfully performed. IFN-β: Interferon β.

The clinical courses of nonencephalopathic patients with prothrombin time <40%. Case 5: A 41-year-old man with acute crisis on chronic hepatitis B. Plasma exchange was performed and he recovered. The pulsatility index was kept under Case 6: A 31-year-old woman with acute hepatitis B. Total bilirubin gradually declined without any aggressive therapy. The pulsatility index was within 1.00 and she recovered.
