Clin Toxicol (Phila). Administer activated charcoal in all patients who are asymptomatic with suspected Amanita ingestion. The Molecular Adsorbent Recirculation System (MARS), a form of hepatic albumin dialysis, may have a role in bridging critically ill patients to liver transplantation or to spontaneous recovery of liver function. J Med Toxicol. Case reports: We present two cases of Amanita mushroom ingestion in the northeastern United States treated with N-acetylcysteine, high-dose penicillin, cimetidine, and silibinin, a semi-purified fraction of milk thistle-derived silymarin, as part of their treatment regimen.

AMATOXIN MUSHROOM POISONING IN NORTH AMERICA 2015-2016 By Michael W. Beug: Chair, NAMA Toxicology Committee Assessing the degree of amatoxin mushroom poisoning in North America is very challenging. Amatoxin poisoning is a medical emergency characterized by a long incubation time lag, gastrointestinal and hepatotoxic phases, coma, and death. The mainstays of treatment of amatoxin ingestion include aggressive IV fluid and electrolyte therapy to correct deficiencies and maintain adequate hydration. Results: 2 authors. Contacting a mycologist for possible mushroom identification may be helpful. 22 (2):124-30. In a subsequent retrospective analysis of 367 patients with suspected amatoxin poisoning, of whom 118 received silibinin alone and 249 silibinin plus penicillin, the investigators reported lower death and transplantation rates in the silibinin group than in the silibinin-penicillin group, though the difference did not prove statistically significant. This website also contains material copyrighted by 3rd parties. 2014 Mar. The clinical manifestations and diagnosis of mushroom poisoning, and the diagnosis and treatment of poisoning caused by mushrooms containing potentially lethal cyclopeptide toxins (eg, amatoxin) and by Amanita smithiana are discussed in greater detail separately. If fulminant hepatic failure (FHF) has developed, a liver transplant service should be consulted. The present paper analyzes the pathogenesis, clinical features, prognostic indicators, and therapeutic strategies of ALF secondary to ingestion of Amanita phalloides, which represents the most common and deadly cause of mushroom poisoning.
