Abstract/Text
BACKGROUND: A nationwide survey was performed to clarify the recent status of acute liver failure (ALF) and late-onset hepatic failure (LOHF) in Japan.
METHODS: Two-step surveys for patients with ALF and LOHF meeting the Japanese diagnostic criteria were performed annually in 782 hospitals. The clinical features of the patients were then compared to those reported in previous surveys.
RESULTS: In total, 1554 and 49 patients with ALF and LOHF, respectively, who were seen between 2010 and 2015 were enrolled. The subjects were classified into 1280 patients with hepatitis (642 non-comatose and 638 comatose) and 323 patients without hepatitis (190 non-comatose and 133 comatose). Compared with patients seen between 1998 and 2009, an older patient age and a higher percentage of underlying extrahepatic disease were observed. Although hepatitis virus infection was the most frequent etiology, the percentage of patients with this etiology had decreased, compared with previous cohorts, while the percentages of patients with drug-induced liver injuries, autoimmune hepatitis, and an indeterminate etiology had increased. Liver transplantation was performed in 170 patients (10.6%), whereas artificial liver support with plasmapheresis and/or hemodiafiltration were performed for most of the comatose patients. The outcomes of comatose patients were unfavorable, similar to previous surveys, especially the outcomes of hepatitis B virus carriers, including those with de novo hepatitis B (survival rate of 5.4% without liver transplantation).
CONCLUSION: Although the clinical features, including the etiologies, of patients with ALF and LOHF have changed, the outcomes of patients have not improved in recent years.
