Response to transarterial chemoembolization as a biological selection criterion for liver transplantation in hepatocellular carcinoma.
Criteria to select patients with hepatocellular carcinoma (HCC) for liver transplantation (LT) are based on tumor size and number of nodules rather than on tumor biology. The present study was undertaken to assess the role of transarterial chemoembolization (TACE) in selecting patients with tumors suitable for LT. Ninety-six consecutive patients with HCC were treated by repeatedly performed TACE, 62 of them exceeding the Milan criteria. Patients meeting the Milan criteria were immediately listed, and patients beyond the listing criteria were listed upon downstaging of the tumor following successful TACE. Fifty patients were finally transplanted. Of these 50 patients, 34 exceeded the Milan c…
High-urgency kidney transplantation in the Eurotransplant Kidney Allocation System : success or waste of organs? The Eurotransplant 15-year all-centre survey
Item does not contain fulltext BACKGROUND: In the Eurotransplant Kidney Allocation System (ETKAS), transplant candidates can be considered for high-urgency (HU) status in case of life-threatening inability to undergo renal replacement therapy. Data on the outcomes of HU transplantation are sparse and the benefit is controversial. METHODS: We systematically analysed data from 898 ET HU kidney transplant recipients from 61 transplant centres between 1996 and 2010 and investigated the 5-year patient and graft outcomes and differences between relevant subgroups. RESULTS: Kidney recipients with an HU status were younger (median 43 versus 55 years) and spent less time on the waiting list compared…
Transience versus recurrence for scale-free spatial networks
Weight-dependent random connection graphs are a class of local network models that combine scale-free degree distribution, small-world properties and clustering. In this paper we discuss recurrence or transience of these graphs, features that are relevant for the performance of search and information diffusion algorithms on the network.
Budd-Chiari Syndrom – eine seltene Manifestation der hereditären Thrombophilie
Das Budd-Chiari Syndrom ist eine seltene Manifestationsform der hereditaren oder erworbenen Thrombophilie. Bei einer 30 jahrigen Patientin konnte, nach anfanglichen diagnostischen Schwierigkeiten, ein BCS diagnostiziert und erfolgreich, durch portocavalen Seit-zu-Seit Shunt, behandelt werden. Bei der Chiari-Trias aus abdominellen Schmerzen, Hepatomegalie und Ascites mus das BCS in die differentialdiagnostischen Uberlegungen mit einbezogen und gegebenenfalls durch invasive Diagnostik ausgeschlossen werden. Therapiemoglichkeiten sind die Anticoagulation und die Anlage eines portosystemischen Shunts (TIPS oder chirurgischer Shunt). Eine Lebertransplantation kommt als ultima ratio bei Leberinsu…
Inhomogeneous long-range percolation in the weak decay regime
We study a general class of percolation models in Euclidean space including long-range percolation, scale-free percolation, the weight-dependent random connection model and several other previously investigated models. Our focus is on the weak decay regime, in which inter-cluster long-range connection probabilities fall off polynomially with small exponent, and for which we establish several structural properties. Chief among them are the continuity of the bond percolation function and the transience of infinite clusters.
Chemokine receptor-5Delta32 mutation is no risk factor for ischemic-type biliary lesion in liver transplantation
It has been shown that certain chemokine receptor polymorphisms may correspond to certain complications after organ transplantation. Ischemic-type biliary lesion (ITBL) encounters for major morbidity and mortality in liver transplant recipients. So far, the exact cause for ITBL remains unclear. Certain risk factors for the development of ITBL like donor age and cold ischemic time are well described. In a previous study, a 32-nucleotide deletion of the chemokine receptor-5Delta32 (CCR-5Delta32) was strongly associated with the incidence of ITBL in adult liver transplantation. This study re-evaluates the association of CCR-5Delta32 gene polymorphism and the incidence of ITBL. 169 patients wer…
Efficacy of an escalating dose regimen of pegylated interferon ?-2a plus ribavirin in the early phase of HCV reinfection after liver transplantation
We evaluated the safety and efficacy of an escalating dose regimen of pegylated interferon alpha-2a (PEG-IFN(alpha-2a)) and ribavirin in the early phase of recurrent hepatitis C after orthotopic liver transplantation (OLT). In this prospective study, 26 patients transplanted for hepatitis C virus cirrhosis with recurrent hepatitis C were treated 3.4 +/- 3.6 months after OLT and compared with an untreated historical control. PEG-IFN(alpha-2a) was initiated as monotherapy, following stepwise dose escalation up to 180 mug/week and the addition of ribavirin up to 1200 mg/day or maximally tolerated doses for 48 weeks. In the intent-to-treat analysis, 38% showed an early virological response (EVR…
