Abstract
Amanita phalloides poisoning is the most common cause of lethal mushroom poisoning (lethality >20% in adults, >50% in children). However, there is no standard treatment strategy and no antidote against the ensuing hepatic failure. This review of 14 investigations published over the last 20 years shows that the introduction of detoxification techniques, in particular the use of plasmapheresis, in combination with supportive therapy to prevent the absorption of aminitine toxins into blood, produced a substantial reduction in mortality. The main complications in using these techniques include infections and coagulation disorders. Because of the latency period in the development of symptoms, treatment should begin on the first suspicion that an intoxication is present. The best therapeutic results can be expected when the detoxification techniques are applied in combination with conservative therapies within the first 36–48 h. Using this approach, mortality rates in some recent studies have been below 10%.
