Liver Failure in Transplanted Liver Due to Amanita Falloides H.F. Kucuk, Z. Karasu, M. Kılıc, and D. Nart ABSTRACT Two patients underwent liver transplantation due to Amanita falloides poisoning. In one of them the clinical symptoms, signs, and laboratory findings related to liver failure were similar to the findings before the transplantation. The patient died and the pathological examination of the liver was similar to the patient’s earlier explanted liver.

ILD MUSHROOM POISONING with Amanita falloides occurs sporadically but is highly mortal. Even with aggressive medical therapy, hepatic and multiorgan failure occur. Orthotropic liver transplantation (OLT) is indicated in mushroom poisoning when medical therapy fails. Forty-one patients with mushroom ingestion were admitted to our hospital in 2002. Supportive treatment was sufficient in 30 whereas 11 patients needed intensive care. Five of 11 patients died; four recovered with medical therapy, and two patients underwent orthotopic liver transplantation. In this paper, we report two cases of mushroom poisoning who underwent OLT.

CASE REPORTS Case 1

A 44-year-old man, previously in good health, was admitted with sudden onset of nausea, severe abdominal pain, and diarrhea. He declared that he had consumed wild mushrooms 8 hours before the symptoms. Despite medical treatment his liver function tests worsened. Grade 3 encephalopathy developed on the day 4. He underwent OLT with the diagnosis of fulminant hepatitis. A cadaveric graft was transplanted with an 11-hour cold ischemia period. The cut surface of the explanted liver was hemorrhagic and had a nutmeg appearance. Massive hemorrhagic necrosis was observed on microscopic examination (Fig 1). Cyclosporine and prednisolone were used for immunosuppressive treatment. After transplantation the liver function tests decreased gradually to nadir values 1 week after OLT. Then they again started to increase suddenly and the clinical situation of the patient worsened. Table 1 shows the laboratory values. There was no vascular abnormality on the Doppler ultrasound examination. Trucut liver biopsy showed massive hemorrhagic necrosis, the same as that in the explanted liver (Fig 2). The patient died 10 days after transplantation. An autopsy showed the gross anatomic and

After postoperative day 2 the patients showed signs of neurological recovery. Her transplanted liver functioned well and the liver function tests decreased to normal levels by day 20 posttransplantation (Table 2). DISCUSSION

It has been reported that one mushroom is sufficient to kill the average adult.1 Phalloidin and amanitins are toxins that can be isolated from the mushroom Amanita phalloides. Phalloidin is a cyclic heptapeptide with a molecular weight of 900 daltons. It interrupts the actin polymerizationdepolymerization cycle, thus impairing cell membrane function. This toxin is responsible for the initial gastrointestinal symptoms of poisoning.2,3 Amanitins are the other group of amanita toxins. ␣-Amanitin is thermostable toxin with molecular weight 900 daltons. After ingestion, it is rapidly absorbed through intestines, binding weakly to serum proteins.4 It rapidly penetrates cell membranes inhibiting RNA polymerase-II in the cytosol, leading to interference with messenger RNA synthesis. Ultimately the failure of production of structural proteins results in cell necrosis.5 Centrilobular necrosis with hemorrhage and fatty degeneration are seen on pathological examination of the liver.2

In the clinical presentation, there is initial latent period of 6 to 48 hours. Then severe gastrointestinal symptoms such as vomiting, diarrhea, and abdominal pain start and continue for 12 to 24 hours. A hepatic phase occurs 48 to 96 hours after ingestion with elevations of serum aminotransferases, coagulopathy, and jaundice. Fulminant hepatic failure develops rapidly within 6 to 16 days after ingestions.6 – 8 Early, aggressive medical management with fluid therapy and treatment of coagulation disorders with fresh-frozen plasma is essential.2 Early gastrointestinal lavage and use of charcoal, intravenous penicillin, and silibin administration are also needed.1,9,10 Once, hepatic coma develops in a patient with mushroom poisoning, the prognosis is poor.5 In the case of encephalopathy, OLT is indicated. Klein et al suggested that prolongation of prothrombin time more than twice normal despite replacement with fresh-frozen plasma, hypoglycemia requiring glucose support, and serum bilirubin levels greater than 25 mg/dL are other indications for transplantation.11 OLT was performed herein for the diagnosis of fulminant hepatic failure and encephalopathy. There was no postoperative problem in case 2; she was discharged with clinical improvement. Although the clinical situation seemed to be good— encephalopathy and hepatic failure improved in early postoprerative period in case 1— he died at 9 days with similar clinical findings as to be pretransplant liver failure.

ical examination of the explanted liver. However, both explants of case 1 (naive liver and transplanted liver in autopsy) showed similar macroscopic and microscopic findings that were in accordance with classical findings in mushroom poisoning. Considering the data that the halflife of mushroom toxins is 2 to 3 days, it is difficult to explain reintoxication of the transplanted liver. It could be speculated that poisons of amanita phalloides were deposites in tissues other than liver causing recurrence of mushroom poisoning after OLT with evidence of clinical symptoms and pathological signs. Another speculation is that some other toxic molecules (nonphalloidin and nonamanitins), which are not yet, described may have caused a fatal outcome.

In conclusion, OLT may be a lifesaving option for fulminant hepatic failure secondary to mushroom poisoning. But more descriptive studies are needed to identify toxic molecules, as well as pharmacokinetic and pharmacodynamic effects of these toxic molecules. REFERENCES 1.
