Background: Benzodiazepine-like compounds have been implicated in the pathogenesis of encephalopathy after fulminant hepatic failure. Methods: The levels and the nature of benzodiazepine-like compounds were determined in six cases of fulminant hepatic failure during the course of the disease. Blood samples were collected on admission and a few days later, when the neurologic status had improved in five cases and immediately before death in one case. The compounds were measured in sera with a binding technique after high-performance liquid chromatography purification and analyzed with mass spectrometry;, Results: Their levels were highly variable in those with severe encephalopathy and were still Increased on awakening in some cases. Diazepam and N-desmethyldiazepam were inconsistently present. Conclusions: The inconsistent presence of benzodiazepine-like compounds in encephalopathy after fulminant hepatic failure and their persistence, in some cases, at high levels on awakening from coma seem to Indicate that the encephalopathy is not strictly dependent on the levels of these compounds.
