Amanita phalloides intoxication: mechanism of toxicity, clinical manifestations and therapeutic approaches
Abstract
Ingestion of Amanita phalloides is the most common cause of fatal mushroom poisoning. The clinical picture of intoxication varies from mild subclinical manifestation to lethal fulminant course with the development of acute liver failure.
Early diagnosis of Amanita phalloides poisoning is crucial for the outcome but i tis difficult because it is often mistaken as gastroenteritis or due to other mushroom poisoning. The diagnosis is based on the history of recent mushroom ingestion followed by gastrointestinal symptoms, typical time course and laboratory markers and is proven with mycological examination or toxicological examination.
Specific treatment consists of detoxification procedures, supportive measures, administration of drugs and therapy in the specialized intensive care unit in the case of acute liver failure. In selected patients with acute liver failure urgent liver transplantation is the only life-saving option.
