title: Fulminant hepatic failure in the elderly: a clinicopathological study of autopsy cases aged over 65 years.
abstract: The pathology of fulminant hepatic failure (FHF) in the elderly is little known because of its very low frequency. Thirteen autopsy cases, all above 65 years of age (mean +/- SD, 72 +/- 6 years), and 10 younger control cases, all below 40 years of age (30 +/- 7 years), were analyzed. The elderly group comprised 10 cases with subacute FHF and three cases with acute FHF, while the younger group comprised seven cases with subacute FHF and three cases with acute FHF. The most predominant pathological type in the elderly group was submassive hepatic necrosis (10 cases), followed by acute hepatitis with bridging hepatic necrosis (AH-BHN; two cases) and massive hepatic necrosis (one case). In two cases of submassive hepatic necrosis, hepatic regeneration seemed to be insufficient for the suggested history. The underlying diseases and terminal complications were significantly more frequent in the elderly group than in the younger group. In conclusion, the immune response in the elderly group is found to be strong enough to cause massive or submassive hepatic necrosis. However, impaired hepatic regeneration is occasionally observed in the elderly cases and AH-BHN is often lethal because of frequent underlying diseases and severe complications.
