ABSTRACT
INTRODUCTION: Amanita phalloides poisoning is a potentially fatal cause of acute liver failure. The aim of this study was to analyze the impact of initial patients' characteristics and different treatment modalities on the outcome of patients with liver failure caused by Amanita poisoning. MATERIAL AND METHODS: We retrospectively evaluated 23 patients admitted to our center between July 2007 and August 2016. RESULTS: Mean time interval between Amanita phalloides ingestion and the onset of gastrointestinal symptoms was 12.48 ± 9.88 hours and the interval between ingestion and hospital admission 26.26 ± 15.14 hours. The treatment was intiated by oral decontamination using activated charcoal followed by intravenous rehydration and high doses of intravenous N-acetylcysteine and silibinin. Fourteen patients (61%) underwent extracorporeal elimination method. Ten patients had plasmapheresis, 1 patient had hemoperfusion, and 5 patients had fractionated plasma separation and adsorption. Seven patients who met King's College Criteria were listed for urgent liver transplantation; one of them died before transplantation. Six patients underwent liver transplantation; the mean waiting time was 6.5 ± 12.0 days (range, 1-31 days). One patient died 2 months afterward. All 16 patients who did not meet King's College Criteria and received conservative treatment survived. CONCLUSION: Our results documented a good prognostic value of standard King's College Criteria for indication of urgent liver transplantation in acute liver failure caused by Amanita phalloides poisoning. Fractionated plasma separation and adsorption may contribute to low mortality on the waiting list. Intensive care and extracorporeal elimination methods seem to be crucial points of the conservative treatment.

BACKGROUND: Hyperchloremia produces renal vasoconstriction and fall in glomerular filtration rate. In 90% of brain-dead organ donors, diabetes insipidus develops, characterized by inappropriate diuresis, hyperosmolality, and hyperchloremia. The aim of this study was to determine the relationship between the serum concentration of chlorides of the donor and the onset of the function of the kidney allograft in the recipient. METHODS: We retrospectively studied 213 donors and kidney allograft recipients. Serum creatinine concentrations and glomerular filtration rates on the 1st, 7th, and 30th days after transplantation of the recipients from hyperchloremic donors were compared with the recipients from normochloremic donors, as well as the incidences of acute tubular necrosis and delayed graft function. RESULTS: On the 1st day, serum creatinine concentrations of the recipients from hyperchloremic and normochloremic donors, respectively, were 448.2 ± 212.1 µmol/L and 502.2 ± 197.8 µmol/L (P = .1), on the 7th day, 168.6 ± 102.6 µmol/L and 196.9 ± 120.6 µmol/L (P = .13), and on the 30th day, 129.4 ± 43.3 µmol/L and 131.8 ± 43.6 µmol/L (P = .73). The differences were statistically significant. The groups also did not differ significantly in glomerular filtration rates and incidences of acute tubular necrosis and delayed graft function. CONCLUSIONS: In this study, no significant correlation between serum chloride concentrations of the organ donors and the onset of the function of kidney allografts in the recipients was found.
