Ingestion of Amanita phalloides is the most common cause of fatal mushroom poisoning. The clinical picture of intoxication varies from mild subclinical manifestation to lethal fulminant course with the development of acute liver failure. Early diagnosis of Amanita phalloides poisoning is crucial for the outcome but i tis difficult because it is often mistaken as gastroenteritis or due to other mushroom poisoning. The diagnosis is based on the history of recent mushroom ingestion followed by gastrointestinal symptoms, typical time course and laboratory markers and is proven with mycological examination or toxicological examination. Specific treatment consists of detoxification procedures, supportive measures, administration of drugs and therapy in the specialized intensive care unit in the case of acute liver failure. In selected patients with acute liver failure urgent liver transplantation is the only life-saving option.

The prevalence of liver cirrhosis in population is increasing, as well as its prevalence among patients admitted to hospital for elective surgery. These patients are at risk of high postoperative morbidity and mortality. Perioperative risk assessment of patients with liver cirrhosis is a complex procedure. It consists of evaluation of general condition of the patient, including comorbidities and nutritional status, evaluation of the grade of liver disease, and urgency of the surgical procedure. There are no specific guidelines. Proper risk assessment before surgery, considering alternative ways of treatment, is a cornerstone of optimal postoperative course and prevention of complications in patients with liver cirrhosis.

Living donor AB0 incompatible kidney transplantation represents a new tool how to improve the access to transplantation. Majority of European protocols are based on desensitization with rituximab, triple drug immunosuppression, intravenous immunoglobulins and specific immunoads option (IA) which eliminates isohaemaglutinins. AB0i kidney transplant program was initiated in our centre in 2011 and 21 patients have received grafts from incompatible donors until recently. Highest accepted isohaemaglutinins titers before rituximab were 1 : 64 and corresponding pretransplant immunoadsorption procedures varied from 2 to 9. In 5 patients 1-2 IA procedures were performed also after transplantation. With the advent of paired exchange program the AB0i transplantation is offered to patients with unsuccessful matching run or with aim to improve HLA match between donor and recipient. The main complications were postoperative bleeding and urinary tract infections in patients at risk. Majority of protocol biopsies exhibited positivity of C4d staining. Neither graft loss nor patient death were noticed.

The Aim of the Study: Was to analyze in detail perioperative changes of renal function during orthotopic liver transplantation (OLT) and to identify risk factors, that were associated with the need of renal replacement therapy (RRT) during the first week after liver transplantation., Methods: Prospective study of 50 consecutive patients undergoing OLT was performed. Selected laboratory and clinical parameters were monitored prior to the procedure, after reperfusion, at the end of the procedure, and at 12 hours after the procedure. In the first post-transplant week, necessity to use RRT in the presence of acute kidney injury was monitored and the analysis of risk factors for the need for RRT was performed. Patient survival, graft function, need for dialysis and selected laboratory parameters were assessed at one year post-transplant., Results: During OLT, there was an increase in S(cr) and S(urea), which persisted as late as 12 hours post-transplant. There was a decrease in U(cr) and U(urea) and an increase in S(Na) and S(K). During the procedure any increase in S(cyst) were observed, increase the values were recorded 12 hours after surgery. S(bili) level decreased. There was a rise in the urinary levels of total protein, albumin and beta2-microglobulin. U(prot)/U(cr) increased significantly after reperfusion, with a peak after the procedure. At 12 hours after the procedure, there was a decrease in U(prot)/U(cr), but the values were still many times higher than those seen preoperatively. RRTwas necessary in 14% cases. Risk factors for acute kidney injury requiring RRT included a higher APACHE score, higher BMI, higher preoperative S(cr) and S(urea), hepatorenal syndrome pretransplant, blood loss and intraoperative hemodynamic instability, postoperative complications and dysfunction of the liver graft. One year after OLT, there was no difference in followed laboratory values between patients requiring postoperative RRT and others; no patient was treated with dialysis., Conclusion: OLT has a major impact on glomerular and tubular renal functions. Our data suggest that patients surviving acute renal injury treated with RRT in the early postoperative period have a high chance of restoring renal function. A sensitive marker of renal injury during OLT seems to be perioperative proteinuria.
