Summary
Since the introduction of model for end‐stage liver disease (MELD) in 2006, post‐orthotopic liver transplantation (OLT) survival in Germany has declined. The aim of this study was to evaluate risk factors and prognostic scores for outcome. All adult OLT recipients in seven German transplant centers after MELD implementation (December 2006–December 2007) were included. Recipient data were analyzed for their influence on 1‐year outcome. A total of 462 patients (mean calculated MELD = 20.5, follow‐up: 1 year) were transplanted for alcoholic cirrhosis (33.1%), hepatocellular carcinoma (26.6%), Hepatitis‐C (17.1%), Hepatitis‐B (9.5%), primary sclerosing cholangitis (5.6%) and late graft‐failure after first OLT before December 2006 (8.7%). 1‐year patient survival was 75.8% (graft survival 71.2%) correlating with MELD parameters and serum choline esterase. MELD score >30 [odds ratio (OR) = 4.17, confidence interval: 2.57–6.78, 12‐month survival = 52.6%, c‐statistic = 0.669], hyponatremia (OR = 2.07), and pre‐OLT hemodialysis (OR = 2.35) were the main death risk factors. In alcoholic cirrhosis (n = 153, mean MELD = 21.1) and hepatocellular carcinoma (n = 123, mean MELD = 13.5), serum bilirubin and the survival after liver transplantation score were independent outcome parameters, respectively. MELD >30 currently represents a major risk factor for outcome. Risk factors differ in individual patient subgroups. In the current German practice of organ allocation to sicker patients, outcome prediction should be considered to prevent results below acceptable standards.
Liver transplantation represents a successful and well-established therapeutic concept for patients with advanced liver diseases. Organ donor shortage continues to pose a significant problem. To ensure fair and transparent allocation of too few post-mortem grafts, the model of end-stage liver disease (MELD)-based allocation was implemented in December 2006. This has decreased waiting list mortality from 20 to 10 % but at the same time has reduced post OLT survival (1-year survival from almost 90% to below 80%), which is largely due to patients with a labMELD score > 30. Following MELD introduction the regular allocation threshold has increased from a matchMELD of initially 25 to meanwhile 34. At the same time the quality of donor organs has seen a continuous deterioration over the last 10 - 15 years: 63% of organs are "suboptimal" with a donor risk index of > 1.5. Moreover, the numbers of living-related liver transplantations have decreased. In Germany incentives for transplant centres are inappropriate: patients with decompensated cirrhosis, high MELD scores and high post-transplant mortality as well as marginal liver grafts are accepted for transplantation without the necessary consideration of outcomes, and against a background of the still absent publication and transparency of outcome results. The outlined development calls for measures for improvement: (i) the increase of donor grafts (e. g., living donation, opt-out solutions, non-heart beating donors), (ii) the elimination of inappropriate incentives for transplant centres, (iii) changes of allocation guidelines, that take the current situation and suboptimal donor grafts into account, and (iv) the systematic and complete collection of transplant-related data in order to allow for the development of improved prognostic scores.
pECLA is a promising alternative compared with conventional pump-driven systems for patients with ARDS and brain injury, since the pECLA system has minor restrictions, limitations and side effects.
A 51-year-old renal transplant recipient presented with marked renal function deterioration 13 months after renal transplantation. After exclusion of ureteral obstruction, transplant artery stenosis and acute rejection, the diagnosis of a severe renal vein stenosis was made by an MR scan. After angiographic confirmation of the stenosis, treatment was attempted with percutaneous stent angioplasty. The long-term clinical course was favorable, with marked improvement in renal function. Transplant renal vein stenosis is a rare, but potentially curable, cause of renal allograft functional deterioration.
