INTRODUCTION Glycogen storage disease type Ia (GSDIa) is due to the deficiency of glucose-6-phosphatase activity in the liver, kidney, and intestine. Although significant progress has been achieved in the management of patients with GSDIa, complications still emerge. The potential for development of liver adenomatosis and kidney failure makes these patients(More)
The Authors describe an optimized procedure for the isolation of rat pancreatic acini and the preliminary results concerning the functional characterization of the cells. Isolation is carried out by two sequential digestive steps in a KREBS modified medium containing collagenase, separated by an intermediate step in which acini separation is fostered by(More)
The serum levels of sHLA-I have been determined in 16 patients following liver transplantation. sHLA-I levels did not show remarkable variations in six patients without evidence of transplant-related complications. sHLA-I levels strongly increased in 10 patients undergoing acute rejection episodes. In these patients, an average 20% daily increase of sHLA-I(More)
The increase in the number of patients awaiting liver transplantation (OLT) has forced the use of cadaveric donors (CD) with suboptimal characteristics. Of these, donor age is perhaps the most investigated parameter. Although excellent outcomes were observed for OLT using CD aged over 60 years, the European Liver Transplant Registry (ELTR) Group found an(More)
Torque Teno Virus (TTV), a nonenveloped human virus of the Circoviridae family, is hepatotropic, causing liver damage, cirrhosis, and, rarely, fulminant hepatitis. It prevails in 10% to 75% of blood donors due to environmental differences, independent of chronic hepatitis B virus (HBV)/HCV hepatitis, cryptogenic cirrhosis, alcoholic cirrhosis, and in(More)
The role of split liver transplantation has been well established. The limitation to this technique is the number of potential recipients for a left lateral segment graft. The optimal use of the donor pool is to split the liver to provide 2 grafts suitable for adults obtaining right or left lobe. We explored the potential increase in the number of liver(More)
Sirolimus (SRL) is an mTOR inhibitor that has been shown, in contrast to calcineurin inhibitors (CNI), to inhibit cancers in experimental models. Since February 2005, we introduced SRL in liver transplant patients in group a, in whom the primary disease was hepatocellular carcinoma (HCC) associated with hepatitis B virus (HBV), hepatitis C virus (HCV),(More)
In many Western countries a "minimum volume rule" policy has been adopted as a quality measure for complex surgical procedures. In Italy, the National Transplant Centre set the minimum number of orthotopic liver transplantation (OLT) procedures/y at 25/center. OLT procedures performed in a single center for a reasonably large period may be treated as a time(More)
