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.

BACKGROUND: Allodynia and hyperalgesia present after surgical interventions are often a major complain of surgical patients. It is thought that both peripheral and central mechanisms contribute to these symptoms. In this study, the role of peripheral nerve fibres that express transient receptor potential vanilloid 1 (TRPV1) receptors in the activation of spinothalamic tract (STT) and postsynaptic dorsal column (PSDC) neurons was assessed in a model of surgical pain. METHODS: Spinothalamic tract and PSDC neurons retrogradely labelled from the thalamus and nucleus gracilis were used. Activation of these projection neurons was evaluated after plantar incision as expression of the early gene product, c-Fos protein, in the nuclei of these neurons. RESULTS: There was a robust increase in c-Fos immunopositivity in the STT and PSDC neurons, in the control animals after a plantar incision. This increase in c-Fos expression was significantly attenuated in animals in which a single high-concentration capsaicin injection was made intradermally at the incision site 24 h before the surgery. CONCLUSIONS: Our results suggest that activation of both STT and PSDC neurons is involved in development of pain states present after surgical incision and that TRPV1-containing peripheral nerve fibres are needed for c-Fos expression in these dorsal horn neurons after plantar incision.

Prometheus, based on modified fractionated plasma separation and adsorption (FPSA) method, is used in the therapy of acute liver failure as a bridge to liver transplantation. As the therapeutic effect of Prometheus is caused not only by the elimination of terminal metabolites, the aim of the study was to identify the effect of FPSA on the levels of cytokines and markers of inflammation and liver regeneration. Previous studies assessing cytokine levels involved mostly acute-on-chronic liver failure patients. Data concerning markers of inflammation and liver regeneration are not published yet. Eleven patients (three males, eight females) with acute liver failure were investigated. These patients underwent 37 therapeutic sessions on Prometheus device. Before and after each treatment, the plasma levels of selected cytokines, tumor necrosis factor alpha (TNFα), C-reactive protein (CRP), procalcitonin (PCT), hepatocyte growth factor (HGF), and α(1) fetoprotein, were measured, and the kinetics of their plasma concentrations was evaluated. Before the therapy, elevated levels of interleukin (IL)-6, IL-8, IL-10, TNFα, CRP, and PCT were detected. The level of TNFα, CRP, PCT, and α(1) fetoprotein decreased significantly during the therapy. In contrast, an increase of HGF was detected. The decline of IL-6, IL-8, and IL-10 concentrations was not significant. Our results show that Prometheus is highly effective in clearing inflammatory mediators responsible for systemic inflammatory response syndrome and affects the serum levels of inflammatory and regeneration markers important for management of acute liver failure.
