title: Antibodies to the surface of halothane-altered rabbit hepatocytes in patients with severe halothane-associated hepatitis.
abstract: Circulating antibodies reacting specifically with the cell membrane of hepatocytes isolated from halothane-anesthetized rabbits were detected in nine of 11 patients with fulminant hepatic failure after helothane-induced anesthesia. The immunoglobulin deposition, as revealed by immunofluorescence, showed a granular pattern on the hepatocyte surface membrane. Preincubation of halothane-pretreated, but not of control, hepatocytes with serum containing this antibody rendered them susceptible to cytotoxic effects of normal lymphocytes in vitro. Control studies using serum from subjects repeatedly exposed to halothane without the development of liver damage, and from patients with viral and toxic liver injury have confirmed the specificity of these findings to serve halothane-associated liver injury. These results provide further evidence of an immunologic component in this condition.
