In a retrospective analysis, the lowest mortality was reported in patients treated with NAC and silibinin, both of which were administered as monotherapy. Diseases & Conditions, 2002 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. 325451-overview Once amatoxin poisoning is identified, there is no clearly effective treatment, leading to a broad range of theoretically beneficial, anecdotally successful, or investigational options. With the exception of liver transplantation, the current treatment strategies for amatoxin poisoning are all supportive and have not been subjected to rigorous efficacy testing in randomized controlled trials. Activated charcoal (1 g/kg) is recommended if the patient is not vomiting and has a protected airway. A retrospective review of 105 patients with amatoxin poisoning from 1988-2002 in Italy showed that all patients treated within 36 hours after ingestion were cured without sequelae. Amatoxin poisoning has a characteristic latent period of 6-12 hours postingestion before onset of clinical symptoms. [Medline]. Results of the following laboratory studies should be monitored for signs of deterioration: Blood urea nitrogen (BUN) and creatinine levels.
