【 要旨 】 劇症肝炎はきわめて予後不良な疾患であるものの,積極的な治療法によって救命率が改善されつつある.本邦における1997年までの救命率は急性型で40%前半,亜急性型は10~20%,全体では25~30%とほぼ横ばいであったが,98年より救命率の改善が認められ,99年全体の救命率は56.3%まで上昇した.この背景には血漿交換療法と(持続的)血液濾過透析を併用する人工肝補助療法を主体とした集学的治療法の普及と生体肝移植の普及によるところが大きいと考えられる.透析患者の急性肝不全は全身合併症が多く,治療は困難を極める.急性肝不全を起こさないよう院内感染防止を中心とした予防策が重要である.

[ Summary ] Fulminant hepatitis is a disorder characterized by extreme lethargy for which the survival rate of patients has long been low. A nationwide survey in Japan disclosed that until 1997 the survivals for the subacute type and the acute type of fulminant hepatitis were 10-20% and 40%, respectively. Recently, intensive care consisting of plasma exchange combined with hemodiafiltration has been considered to be effective for the management of fulminant hepatitis. Liver transplantation has also been initiated for the same purpose here in Japan. These aggressive therapies are sometimes called "artificial liver support". As a result of these intensified treatments, the survival rate of patients with fulminant hepatitis has improved with a survey showing the survival rate to now be over 56%.
Although there have been very few cases of fulminant hepatitis among hemodialyzed patients, once it develops the survival rate of these patients is still extremely low. Most of the known cases are considered to be the result of in-hospital infection with hapatitis B virus. This has been due to transfection of such virus of hemodialyzed patients in the hemodialysis center. Therefore, infectious accidents should be avoided.
