ABSTRACT
Consumption of toxic mushrooms belonging to the genus Amanita frequently leads to severe gastrointestinal distress followed by acute hepatic failure with a fatal outcome. In Thailand, valuable information as to the locally prevalent poisonous species, the preferred habitat and the management of suspected victims of intoxication is basically non-existent. We report here 5 cases of fatal poisoning with Amanita virosa having occurred in a family residing in the northeast of Thailand who as countless others had enjoyed mushroom gathering as a pasttime. Within 4 to 6 days after ingestion of the mushrooms, all had succumbed to acute hepatic failure with subsequent hepatoencephalopathy. Treatment modalities exist in the form of penicillin and silibinin, or thioctic acid administration followed by plasmapheresis. In cases taking a lethal course apparent from the results of liver biochemistry, liver transplantation is clearly indicated. In order to prevent mushroom poisoning altogether, educating the general population to that end certainly presents the method of choice.
