BACKGROUND/AIMS To investigate the effect of sustained virological response (SVR) on impaired fasting glucose (IFG) and/or type 2 diabetes (T2DM); to assess the influence of glucose abnormalities on the SVR rate. METHODS 1059 patients with chronic HCV; normal glucose (< 100 mg/dl) in 734, IFG (between 100 and 125 mg/dl) in 218, and T2DM (126 mg/dl) in 107(More)
A fraction of liver transplant recipients are able to discontinue all immunosuppressive therapies without rejecting their grafts and are said to be operationally tolerant to the transplant. However, accurate identification of these recipients remains a challenge. To design a clinically applicable molecular test of operational tolerance in liver(More)
INTRODUCTION The search for alternative sources for transplant organs leads us to the search for animals as an inexhaustible source of organs. The objective of this study was to analyze whether livers from polytransgenic pigs expressing the human complement regulatory proteins CD55 (hDAF), CD59, and alfa alpha1,2-fucosyltransferase (H-transferase),(More)
We present ten patients who suffered from a cyclopeptide syndrome from two different foci, one caused by Lepiota helveola (seven cases) and the other by Lepiota brunneoincarnata (three cases). Of the ten victims, five recovered completely after the intestinal stage and the other five developed a phase of visceral involvement with alterations of liver(More)
A retrospective cohort multicenter study was conducted to analyze the risk factors for tumor recurrence after liver transplantation (LT) in cirrhotic patients found to have an intrahepatic cholangiocarcinoma (iCCA) on pathology examination. We also aimed to ascertain whether there existed a subgroup of patients with single tumors ≤2 cm ("very early") in(More)
OBJECTIVE To evaluate the outcome of patients with hepatocellular-cholangiocarcinoma (HCC-CC) or intrahepatic cholangiocarcinoma (I-CC) on pathological examination after liver transplantation for HCC. BACKGROUND Information on the outcome of cirrhotic patients undergoing a transplant for HCC and with a diagnosis of HCC-CC or I-CC by pathological study is(More)
INTRODUCTION Due to the scarcity of donors and the fact that size is the main prognostic factor, Milan criteria have been used since 1996 to select hepatocellular carcinoma (HCC) patients for liver transplantation. In 2001 UCSF criteria showed that including layer tumors did not reduce the survival results. The objective of this paper was to evaluate(More)
The objective of this study was to evaluate the effect of the surgical technique on postoperative renal function during the first week after liver transplantation (OLT). We performed a retrospective study of 184 consecutive OLT. Criteria for acute renal failure were: serum creatinine >1.5 mg/dL, an increase by 50% in the baseline serum creatinine, or(More)
OBJECTIVE The purpose of this retrospective survey was to determine the prevalence and outcome of hepatitis C virus (HCV) infection in cirrhotic patients undergoing liver transplantation (OLT) in Spain in 1992. METHODS Post-OLT HCV infection was defined by anti-HCV (second-generation ELISA) and/or PCR. Patients were divided into groups A (HCV-positive(More)
