Prospective validation of a noninvasive index for predicting liver fibrosis in hepatitis C virus-infected liver transplant recipients

2009

We previously developed a mathematical model, the Hospital Universitario La Fe (HULF) index, as an alternative to protocol liver biopsy (PLB) to estimate significant fibrosis (SF) in patients who underwent liver transplantation (LT) for liver damage caused by chronic HCV infection. In the present study, we sought to validate this noninvasive index. The commonly derived clinical and laboratory data for calculating the HULF index were prospectively collected over 2.7 years from patients undergoing LT and PLB. The sensitivity, specificity, positive and negative predictive values, and diagnostic capacity were evaluated with receiver operating characteristic curve analysis. Biopsy was performed …

Liver Preservation by Aortic Perfusion Alone Compared With Preservation by Aortic Perfusion and Additional Arterial Ex Situ Back-Table Perfusion With…

2017

Background. Arterial ex situ back-table perfusion (BP) reportedly reduces ischemic-type biliary lesion after liver transplantation. We aimed to verify these findings in a prospective investigation. Methods. Our prospective, randomized, controlled, multicenter study involved livers retrieved from patients in 2 German regions, and compared the outcomes of standard aortic perfusion to those of aortic perfusion combined with arterial ex situ BP. The primary endpoint was the incidence of ischemic-type biliary lesions over a follow-up of 2 years after liver transplantation, whereas secondary endpoints included 2-year graft survival, initial graft damage as reflected by transaminase levels, and fu…

Milan-out Criteria and Worse Intention-to-Treat Outcome Postliver Transplantation

2019

Background. Milan criteria are widely used for liver transplantation selection in hepatocellular carcinoma but have been recognized to be too restrictive. Milan-out criteria are increasingly being adopted. Our aim was to analyze if liver transplantation waitlisted Milan-out hepatocellular carcinoma patients have different outcome than Milan patients. Methods. Retrospective study including all consecutive patients with hepatocellular carcinoma admitted in the waiting list for liver transplantation between January 2012 and January 2015. We included 177 patients, 146 of which eventually transplanted. Downstaging was achieved in the Milan-out cases (n = 29) before waitlisting. Results. From dia…

Expanded criteria for liver transplantation in patients with cirrhosis and hepatocellular carcinoma

2008

Orthotopic liver transplantation (OLT) selection for patients with hepatocellular carcinoma (HCC) is a matter of debate. The Milan criteria (MC) have been largely adopted by the international community. The main aim of this study was to evaluate the survival rates and recurrence probabilities of a new proposal for criteria (up to 3 tumors, each no larger than 5 cm, and a cumulative tumor burden </= 10 cm). Patients with cirrhosis and HCC included on the waiting list (WL) from 1991 to 2006 were retrospectively analyzed. Outcomes in patients who had tumors within and beyond the MC were compared. The survival analysis was done (1) with the intention-to-treat principle and (2) among transplante…

Clinical symptomatic de novo systemic transthyretin amyloidosis 9 years after domino liver transplantation

2009

Four years ago, Stangou et al. reported a patient who developed clinical symptoms of amyloidosis 8 years after domino liver transplantation (DLT). In order to alleviate the graft shortage, livers from patients with familial amyloidotic polyneuropathy (FAP) are used as domino grafts for other patients under the assumption that several decades will pass before clinical symptoms due to amyloid accumulation emerge. We now report on another case, the third reported case in the literature, of de novo systemic amyloidosis in a 75-year-old woman 9 years after DLT. The patient underwent DLT at 65 years of age for hepatocellular carcinoma exceeding the Milan criteria in hepatitis C cirrhosis. Transar…

Worse recent efficacy of antiviral therapy in liver transplant recipients with recurrent hepatitis C: Impact of donor age and baseline cirrhosis

2009

We hypothesized that antiviral efficacy [sustained virologic response (SVR)] has improved in recent years in the transplant setting. Our aim was to assess whether the efficacy of pegylated interferon (PegIFN)–ribavirin (Rbv) has improved over time. One hundred seven liver transplant patients [74% men, 55.5 years old (range: 37.5–69.5), 86% genotype 1a or 1b] were treated with PegIFN-Rbv for 355 (16–623) days at 20.1 (1.7–132.6) months after transplantation. Tacrolimus was used in 61%. Sixty-seven percent had baseline F3–F4 (cirrhosis: 20.5%). Donor age was 49 (12–78) years. SVR was achieved in 39 (36.5%) patients, with worse results achieved in recent years (2001–2003: n = 27, 46.5%; 2004: …

Results of the TOP Study: Prospectively Randomized Multicenter Trial of an Ex Vivo Tacrolimus Rinse Before Transplantation in EDC Livers

2016

Background. Organ shortage results in the transplantation of extended donor criteria (EDC) livers which is associated with increased ischemia-reperfusion injury (IRI). Experimental studies indicate that an organ rinse with the calcineurin inhibitor tacrolimus before implantation protects against IRI. The tacrolimus organ perfusion study was initiated to examine the effects of ex vivo tacrolimus perfusion on IRI in transplantation of EDC livers. Methods. A prospective randomized multicenter trial comparing ex vivo perfusion of marginal liver grafts (>= 2 EDC according to Eurotransplant manual) with tacrolimus (20 ng/mL) or histidine-tryptophane-ketoglutarate solution (control) was carried ou…

Progression of transthyretin (TTR) amyloidosis in donors and recipients after domino liver transplantation-a prospective single-center cohort study

2018

Liver transplantation (LT) is the first-line therapy in patients with transthyretin (TTR) amyloidosis and progressive familial amyloid polyneuropathy (FAP). Explanted organs from these patients can be used for domino liver transplantation (DLT). After DLT, de novo amyloidosis may develop in domino recipients (DR). Data were collected prospectively in a transplant database. Electroneurography by nerve conduction velocity (NCV), quantitative sensory testing, heart rate variability (HRV), sympathetic skin response, orthostatic reaction (tilt table test), transthoracic echocardiography, cardiac MRI and organ biopsy results were evaluated. The cohort included 24 FAP- (11 Val30Met, 13 nonVal30Met…

Controlling Diabetes After Liver Transplantation: Room for Improvement.

2016

BACKGROUND Diabetes mellitus is a chronic illness with great impact on long-term outcome after liver transplantation (LT). Despite this, the current level of glycemic control and quality of screening strategies for diabetes-associated conditions that are being provided to liver transplant recipients with diabetes have not yet been assessed. METHODS We performed a cross-sectional, multicenter study that included 344 liver transplant recipients and examined the level of glycemic control and its associated factors, as well as the quality of screening strategies for diabetes-associated conditions. RESULTS Seventy-five patients (21.8%) suffered from diabetes before transplantation, and 82 (23.8%…
