Acute poisoning due to ingestion of hepatotoxic Amanita sp. mushrooms can result in a spectrum of symptoms, from mild gastrointestinal discomfort to life-threatening acute liver failure. With conventional treatment, Amanita phalloides mushroom poisoning carries a substantial risk of mortality and many patients require liver transplantation. The molecular adsorbent recirculating system (MARS) is an artificial liver support system that can partly compensate for the detoxifying function of the liver by removing albumin-bound and water-soluble toxins from blood. ⋯ One patient underwent a successful liver transplantation. No serious adverse side-effects were observed with the MARS treatment. In conclusion, MARS treatment seems to offer a safe and effective treatment option in Amanita mushroom poisoning.

The aim of this study was to evaluate the improvement of prognostic parameters after treatment with the molecular adsorbent recirculating system (MARS) in patients with fulminant hepatitis (FH). The parameters conducive to a positive prognosis include: Glasgow Coma Scale (GCS) score >/=11, intracranial pressure (ICP) <15 mm Hg or an improvement of the systolic peak flow of 25-32 cm/s via Doppler ultrasound in the middle cerebral artery, lactate level <3 mmol/L, tumor necrosis factor-alpha <20 pg/mL, interleukin (IL)-6 <30 pg/mL, and a change in hemodynamic instability from hyperkinetic to normal kinetic conditions, and so define the timing (and indeed the necessity) of a liver transplant (LTx). From 1999 to 2008 we treated 45 patients with FH with MARS in the intensive care unit of our institution. ⋯ We stratified the entire population into three different groups according to six risk factors (the percentage reduction of lactate, IL-6 and ICP, systemic vascular resistance index values, GCS <9, and the number of MARS treatments): group A (0-2 risk factors), group B (3-4 risk factors), and group C (5-6 risk factors). Analyzing the prevalence of these parameters, we noted that group A perfectly corresponded to the NLR group, group B corresponded to the BLT group, and group C was composed of patients from the non-survival group; thus, we were able to select the patients who could undergo a LTx using the predictive criteria. For patients with an improvement of neurological status, cytokines, lactate, and hemodynamic parameters, LTx was no longer necessary and their treatment continued with MARS and standard medical therapy.
