Liver damage from Amanita phalloides is related to the amanitins, powerful toxins that inhibit RNA polymerase II resulting in a deficient protein synthesis and cell necrosis. The mainstays of treatment of amatoxin ingestion include aggressive IV fluid and electrolyte therapy to correct deficiencies and maintain adequate hydration. However, not all Amanita species have this toxin, and other mushroom species besides Amanita have the amatoxin. The major amatoxins, the alpha-, beta-, and gamma-amanitins, are bicyclic octapeptide derivatives that damage the liver and kidney via irreversible binding to RNA polymerase II. All patients with amatoxin poisoning should be admitted for aggressive supportive care, monitoring of hepatic function, and observation for progression to later stages of poisoning.

Amatoxin, a peptide contained in several mushroom species, accounts for the majority of severe mushroom poisonings by binding to RNA polymerase II irreversibly, leading to severe hepatonecrosis. Amatoxin poisoning is a medical emergency characterized by a long incubation time lag, gastrointestinal and hepatotoxic phases, coma, and death. In addition to absence of antidote, no chemotherapeutic consensus was reported. [11] Montanini S, Sinardi D, Pratico C, Sinardi AU, Trimarchi G.
