[Liver transplantation in acute and acute-on-chronic liver failure].

Acute liver failure (ALF) and acute-on-chronic liver failure (ACLF) are diseases with a rapidly progressive course and high mortality. Apart from treating the underlying triggers and intensive care measures, there are very limited therapeutic options for either condition. Liver transplantation is often the only life-saving treatment, but it cannot always be employed due to contraindications and severe disease progression.

Effect of Preoperative Chemotherapy on the Isolation Outcome of Primary Human Hepatocytes.

Primary human hepatocytes isolated from surgically resected liver tissue are an essential resource for pharmaceutical and toxicological studies. Patients undergoing partial liver resections have often received preoperative chemotherapy. The aim of our study was to investigate whether preoperative chemotherapy has effects on the outcome of cell isolation or the metabolic function of cultured hepatocytes.

Liver Transplantation for Metamizole induced Acute Liver Failure.

Metamizole, or dipyrone, is a frequently prescribed analgetic drug that can cause drug-induced liver injury (DILI). Still, there are only a few metamizole-associated DILI cases (n = 61, including our study) described in the literature. So far liver transplantation has been reported in 6 patients with metamizole-induced acute liver failure.

Outcomes of Liver Resections after Liver Transplantation at a High-Volume Hepatobiliary Center.

Although more than one million liver transplantations have been carried out worldwide, the literature on liver resections in transplanted livers is scarce. We herein report a total number of fourteen patients, who underwent liver resection after liver transplantation (LT) between September 2004 and 2017. Hepatocellular carcinomas and biliary tree pathologies were the predominant indications for liver resection (n = 5 each); other indications were abscesses (n = 2), post-transplant lymphoproliferative disease (n = 1) and one benign tumor.

The human liver matrisome - Proteomic analysis of native and fibrotic human liver extracellular matrices for organ engineering approaches.

The production of biomaterials that endow significant morphogenic and microenvironmental cues for the constitution of cell integration and regeneration remains a key challenge in the successful implementation of functional organ replacements. Despite the vast development in the production of biological and architecturally native matrices, the complex compositions and pivotal figures by which the human matrisome mediates many of its essential functions are yet to be defined. Here we present a thorough analysis of the native human liver proteomic landscape using decellularization and defatting protocols to create extracellular matrix scaffolds of natural origin that can further be used in both bottom-up and top-down approaches in tissue engineering based organ replacements.

Dual versus single vessel normothermic ex vivo perfusion of rat liver grafts using metamizole for vasodilatation.

Background: Normothermic ex vivo liver perfusion (NEVLP) is a promising strategy to increase the donor pool in liver transplantation. Small animal models are essential to further investigate questions regarding organ preservation and reconditioning by NEVLP. A dual vessel small animal NEVLP (dNEVLP) model was developed using metamizole as a vasodilator and compared to conventional portovenous single vessel NEVLP (sNEVLP).

Prevalence of Steatosis Hepatis in the Region: Impact on Graft Acceptance Rates.

Due to the shortage of liver allografts and the rising prevalence of fatty liver disease in the general population, steatotic liver grafts are considered for transplantation. This condition is an important risk factor for the outcome after transplantation. We here analyze the characteristics of the donor pool offered to the from 2010 to 2016 with respect to liver allograft nonacceptance and steatosis hepatis.
