Adult Living Donor Liver Transplantation with ABO-Incompatible Grafts: A German Single Center Experience
Adult living donor liver transplantations (ALDLTs) across the ABO blood group barrier have been reported in Asia, North Americas, and Europe, but not yet in Germany. Several strategies have been established to overcome the detrimental effects that are attached with such a disparity between donor and host, but no gold standard has yet emerged. Here, we present the first experiences with three ABO-incompatible adult living donor liver transplantations in Germany applying different immunosuppressive strategies. Four patient-donor couples were considered for ABO-incompatible ALDLT. In these patients, resident ABO blood group antibodies (isoagglutinins) were depleted by plasmapheresis or immunoadsorption and replenishment was inhibited by splenectomy and/or B-cell-targeted immunosuppression. Despite different treatments ALDLT could safely be performed in three patients and all patients had good initial graft function without signs for antibody-mediated rejection (AMR). Two patients had long-term graft survival with stable graft function. We thus propose the feasibility of ABO-incompatible ALDLT with these protocols and advocate further expansion of ABO incompatible ALDLT in multicenter trials to improve efficacy and safety
Pantoprazole Does not Affect Serum Trough Levels of Tacrolimus and Everolimus in Liver Transplant Recipients
Background: Liver transplant recipients are frequently treated with proton pump inhibitors. Drug interactions have been described especially with respect to omeprazole. Due to the lower binding capacity of pantoprazole to CYP2C19 this drug became preferred and became the most used proton pump inhibitor in Germany. The data on the influence of pantoprazole on immunosuppressive drugs in liver transplant recipients a very scarce.Methods: The authors performed a single center analysis in liver transplant recipients on the effect of pantoprazole on the serum trough levels of different immunosuppressants. The trough levels were compared over a period of 1 year before and after start or stop of a continuous oral co-administration of 40 mg pantoprazole once daily.Results: The serum trough levels of tacrolimus (n = 30), everolimus (n = 7), or sirolimus (n = 3) remain constant during an observation period of at least 1 year before and after co-administration of pantoprazole. None of the included patients needed a change of dosage of the observed immunosuppressants during the observation period.Conclusions: The oral co-administration of pantoprazole is safe in immunosuppressed liver transplant recipients according to the serum trough levels of tacrolimus, everolimus, and sirolimus. This analysis provides first data on the influence of pantoprazole on immunosuppressive drugs in liver transplant recipients
Posterior cavoplasty: a new approach to avoid venous outflow obstruction and symptoms for small-for-size syndrome in right lobe living donor liver transplantation
Acute paranoid psychosis as sole clinical presentation of hepatic artery thrombosis after living donor liver transplantation
<p>Abstract</p> <p>Background</p> <p>Hepatic artery thrombosis is a devastating complication after orthotopic liver transplantation often requiring revascularization or re-transplantation. It is associated with considerably increased morbidity and mortality. Acute cognitive dysfunction such as delirium or acute psychosis may occur after major surgery and may be associated with the advent of surgical complications.</p> <p>Case presentation</p> <p>Here we describe a case of hepatic artery thrombosis after living-donor liver transplantation which was not preceded by signs of liver failure but rather by an episode of acute psychosis. After re-transplantation the patient recovered without sequelae.</p> <p>Conclusion</p> <p>This case highlights the need to remain cautious when psychiatric disorders occur in patients after liver transplantation. The diagnostic procedures should not be restricted to medical or neurological causes of psychosis alone but should also focus vascular complications related to orthotopic liver transplantation.</p

Six month abstinence rule for liver transplantation in severe alcoholic liver disease patients
Obed A, Stern S, Jarrad A, Lorf T. Six month abstinence rule for liver transplantation in severe alcoholic liver disease patients. World Journal of Gastroenterology. 2015;21(14):4423-4426.Alcoholic liver disease (ALD) is the second most common diagnosis among patients undergoing liver transplantation (LT). The recovery results of patients transplanted for ALD are often at least as good as those of patients transplanted for other diagnoses and better than those suffering from hepatitis C virus, cryptogenic cirrhosis, or hepatocellular carcinoma. In the case of medically non-responding patients with severe acute alcoholic hepatitis or acute-on chronic liver failure, the refusal of LT is often based on the lack of the required alcohol abstinence period of six months. The obligatory abidance of a period of abstinence as a transplant eligibility requirement for medically non-responding patients seems unfair and inhumane, since the majority of these patients will not survive the six-month abstinence period. Data from various studies have challenged the 6-mo rule, while excellent survival results of LT have been observed in selected patients with severe alcoholic hepatitis not responding to medical therapy. Patients with severe advanced ALD should have legal access to LT. The mere lack of pre-LT abstinence should not be an obstacle for being listed
Ten years survival with excellent outcome after living donor liver transplantation from 70 years old donor for primary hepatic neuroendocrine carcinoma: Case report
AbstractBACKGROUNDPrimary hepatic carcinoid tumors (PHCT) are rare entities; they are even rarer than extrahepatic neuroendocrine gastrointestinal tumors with only about 95 cases reported in the literature. An extrahepatic primary tumor must be excluded to confirm the diagnosis of PHCT.CASE PRESENTATIONWe report a case of a 42-year-old male patient with a primary hepatic neuroendocrine carcinoma, who successfully underwent living donor liver transplantation from his 70 years old mother with 10 years follow-up. Both donor and recipient are still alive and in the good health.CONCLUSIONLiving liver donation from elderly donors for the patients with irresectable neuroendocrine liver malignancies can be as safe as deceased donation or liver donation from young donors (age<50). Living donation from elderly donors might significantly expand the donor pool for patients with liver neuroendocrine tumors (NET) and potentially reduce waiting list mortality. Especially young patients with irresectable NET can benefit from this option. However, case–control studies are needed to verify the advantage of living liver transplantation (LDLT) for the patients with irresectable liver NET and to define selection criteria for these patients
