Amanitin poisonings are among the most life-threatening mushroom poisonings, and are mainly caused by the genus Amanita. Hepatotoxicity is the hallmark of amanitins, powerful toxins contained in these mushrooms, and can require liver transplant. Among amatoxins, α-amanitin is the most studied. Read More

Amanita phalloides related toxicity from amatoxins can result in acute liver and multi-organ failure and is responsible for 90% of all mushroom poisoning death. However, more evidence is needed in regards to different management strategies. We present two cases of amanita mushroom ingestion who were treated with intravenous rifampicin. Read More

Mushroom toxicity is the main branch of foodborne poisoning, and liver damage caused by amatoxin poisoning accounts for more than 90 % of deaths due to mushroom poisoning. Alpha-amatoxin (α-AMA) has been considered the primary toxin from amatoxin-containing mushrooms, which is responsible for hepatotoxicity and death. However, the mechanism underlying liver failure due to α-AMA remains unclear. Read More

The mushroom poison that causes the most deaths is the class of toxins known as amatoxins. Current methods to sensitively and selectively detect these toxins are limited by the need for expensive equipment, or they lack accuracy due to cross-reactivity with other chemicals found in mushrooms. In this work, we report the development of a competition-based lateral flow immunoassay (LFIA) for the rapid, portable, selective, and sensitive detection of amatoxins. Read More

Rapid and accurate identification of multiple toxins for clinical diagnosis and treatment of mushroom poisoning cases is still a challenge, especially with the lack of authentic references. In this study, we developed an effective method for simultaneous identification of amanita peptide toxins by liquid chromatography coupled with photodiode array detection and ion trap time-of-flight mass spectrometry. The accuracy and selectivity of the methodology were validated through similar multiple fragmentation patterns and characteristic ions of standard α- and β-amanitin. Read More

Amatoxin poisoning induces delayed-onset acute liver failure, which are responsible for more than 90% of deaths in mushroom poisoning. It has been postulated from animal and human studies that biliary drainage interrupting enterohepatic amatoxin circulation may affect amatoxin poisoning. Dogs were randomly divided into four groups of six animals each. Read More

Amatoxins are produced primarily by 3 species of mushrooms: Amanita, Lepiota, and Galerina. Because amatoxin poisonings are increasing, the objective of this review was to identify all amatoxin-containing mushroom species, present a toxidromic approach to earlier diagnoses, and compare the efficacies and outcomes of therapies. To meet these objectives, Internet search engines were queried with keywords to select peer-reviewed scientific articles on amatoxin-containing mushroom poisoning and management. Read More

Background: As the currently known diagnostic DNA targets amplified in the PCR assays for detection of poisonous mushrooms have their counterparts in edible species, there is a need to design PCR primers specific to the genes encoding amanitins and phallotoxins, which occur only in poisonous mushrooms.

Objective: The aim of the study was testing of PCR-based method for detection of all genes encoding hepatotoxic cyclic peptides - amanitins and phallotoxins present in the most dangerous poisonous mushrooms.

Material And Methods: Degenerate primers in the PCR were designed on the basis of amanitins (n=13) and phallotoxins (n=5) genes in 18 species of poisonous mushrooms deposited to Genbank of the National Center for Biotechnology Information. Read More

There are few data estimating the human lethal dose of amatoxins or of the toxin level present in ingested raw poisonous mushrooms. Here, we present a patient who intentionally ingested several wild collected mushrooms to assess whether they were poisonous. Nearly 1 day after ingestion, during which the patient had nausea and vomiting, he presented at the emergency department. Read More

Mushroom poisonings occur when ingestion of wild mushrooms containing toxins takes place, placing the consumers at life-threatening risk. In the present case report, an unusual multiple poisoning with isoxazoles- and amatoxins-containing mushrooms in a context of altered mental state and poorly controlled hypertension is presented. A 68-year-old female was presented to São João hospital (Portugal) with complaints of extreme dizziness, hallucinations, vertigo and imbalance, 3 h after consuming a stew of wild mushrooms.

Serious to fatal toxicity may occur with amanitin-containing mushrooms ingestions. A Lepiota brunneoincarnata familial poisoning with hepatic toxicity is reported. In such poisonings, acute gastroenteritis may be firstly misdiagnosed leading to delay in preventing liver dysfunction by silibinin or penicillin G. Read More

Death cap (Amanita phalloides) is commonly found and is one of the five most toxic fungi in Denmark. Toxicity is due to amatoxin, and poisoning is a serious medical condition, causing organ failure with potential fatal outcome. Acknowledgement and clarification of exposure, symptomatic and focused treatment is of primary importance. Read More

Poisoning from Amanita group of mushrooms comprises approximately 3% of all poisonings in our country and their being responsible for nearly the entire fatal mushroom poisonings makes them important. These mushrooms contain primarily two types of toxins, amatoxins and phallotoxins. Phallotoxins have a more limited toxicity potential and they primarily consist of phalloidin (PHN) and phallacidin (PCN). Read More

Background: Diagnosis and management of Amanita mushroom poisoning is a challenging problem for physicians across the United States. With 5902 mushroom exposures and two resultant deaths directly linked to Amanita ingestion in 2009, it is difficult for physicians to determine which patients are at risk for lethal toxicity. Identification of amatoxin poisoning can prove to be difficult due to delay in onset of symptoms and difficulty with identification of mushrooms. Read More
