Abstract:
The fatality rate of liver failure caused by fatal amanita poisoning is high, and there are no effective antidote drugs in China. On July 30, 2020, the department of infectious diseases and liver diseases of the First People's Hospital of Yunnan Province admitted a 67-year-old female patient with liver failure caused by fatal amanita poisoning. The patient went to the emergency department for treatment due to abdominal pain, vomiting and diarrhea after eating 350-400 g of amanita mushroom for 2 days, accompanied by fatigue for 1 day. There was no abnormality in physical examination. Laboratory indexes: alanine aminotransferase (ALT) 4 798 U/L, aspartate aminotransferase (AST) 10 030 U/L, activated partial thromboplastin time (APTT) 57.5 s, prothrombin time (PT) 72.1 s, international normalized ratio (INR) 8.66, prothrombinactivity (PA) 10%. Based on the patient's medical history, clinical manifestations and laboratory data, the diagnosis was amanita peptide mushroom poisoning and acute liver failure. According to the mechanism of amanita toxin poisoning as enterohepatic circulation, endoscopic retrograde cholangiopancreatography and ultrasound-guided gallbladder puncture and drainage for drainage of bile to discharge toxins were performed to interrupt the enterohepatic circulation of toxins. However, both methods failed, so open cholecystostomy was performed. Because the patient's coagulation function was very poor, artificial hepatic plasma exchange was given to improve coagulation function before open cholecystostomy, and eventually bile was drained successfully. After a total of 19 days of comprehensive medical treatment, the patient was cured and discharged from the hospital, and no sequelae was found after 1 year of follow-up. For such patients, early identification of the disease is required, and blocking the enterohepatic circulation of toxins as soon as possible according to the characteristics and toxicological mechanism of toxins may be the key treatment for rescuing patients with liver failure poisoned by amanita toxin, and it is necessary to combine comprehensive treatments such as active fluid replacement and blood purification to further improve the survival rate.
