Background: Amanita verna is one of the most harmful wild fungi in China. Amanita verna poisoning occurs every year, and the mortality is as high as 50%. However, its clinical manifestations are complex and diverse.
Case presentation: In March 2019, three patients took a large amount of Amanita, and one of them received liver transplantation in Zhongshan hospital, Sun Yat-sen University. All patients had vomiting and diarrhea 8-12 h after eating wild mushrooms (Amanita). The patients were initially diagnosed with Amanita poisoning. One case (case 3) was complicated and diagnosed as mushroom poisoning (fatal Amanita), toxic hepatitis, acute liver failure, toxic encephalopathy, hemorrhagic colitis, toxic myocarditis, disseminated intravascular coagulation (DIC) and pregnancy. The general clinical data of all patients were recorded, who received early treatment such as hemodialysis, artificial liver plasma exchange, hormone shock and anti-infection. One case (case 1) recovered smoothly after liver transplantation, and the indexes of liver, kidney, coagulation function and infection were improved. The other two cases died of intracerebral hemorrhage.
Conclusion: Liver transplantation is an effective method for the treatment of acute liver failure caused by mushroom poisoning and can improve the survival rate of patients with toxic liver failure.
