Gastrointestinal transplantation: An update

Nagappan Kumar, David Grant – 30 December 2003 – Gastrointestinal transplantation is a life‐saving option for patients who have chronic intestinal failure and cannot tolerate total parenteral nutrition (TPN). Early referral is important because of the scarcity of donors and the increased risk of complications in debilitated recipients. One‐year patient survival rates range from 50% to 70%. Despite the use of intense immune suppression, most patients experience at least 1 episode of graft rejection. More than 80% of the survivors are able to stop TPN and resume an unrestricted oral diet.

Role of transarterial chemoembolization before liver resection for hepatocarcinoma

Giorgio Enrico Gerunda, Daniele Neri, Roberto Merenda, Franco Barbazza, Fabio Zangrandi, Francesco Meduri, Marco Bisello, Michele Valmasoni, Antonio Gangemi, Alvise Maffei Faccioli – 30 December 2003 – The aim of this study was to clarify whether chemoembolization (TACE) before liver resection (LR) can reduce postoperative hepatocellular carcinoma (HCC) recurrence and improve disease‐free and overall survival. Eighty‐nine patients with tumor‐stage (TNM) I‐II HCC were evaluated for LR. Patients were prospectively allocated to LR alone or TACE plus LR based on their place of residence.

Increased risk for posttransplant lymphoproliferative disease in recipients of liver transplants with hepatitis C

Kevin McLaughlin, Sandra Wajstaub, Paul Marotta, Paul Adams, David R. Grant, William J. Wall, Anthony M. Jevnikar, Kamilla S. Rizkalla – 30 December 2003 – Posttransplant lymphoproliferative disease (PTLD) is associated with immunosuppression and lymphotrophic viral infections. Hepatitis C virus (HCV) has been identified as a risk factor for non‐Hodgkin's lymphoma, but no association between HCV and PTLD has been shown.

Predictive value of the variceal pressure response to continued pharmacological therapy in patients with cirrhosis and portal hypertension

Àngels Escorsell, Josep Maria Bordas, Beatriz Castañeda, Josep Llach, Joan Carles García‐Pagán, Joan Rodés, Jaume Bosch – 30 December 2003 – Noninvasive measurements of variceal pressure adequately reflect the hemodynamic effects of propranolol on portal hypertension. However, the prognostic value of variceal pressure responses during continued propranolol therapy has not been evaluated, and it is unclear whether this may substitute invasive measurements of portal pressure response.

Functional significance of endothelin B receptors in mediating sinusoidal and extrasinusoidal effects of endothelins in the intact rat liver

Michael Bauer, Inge Bauer, Natalie V. Sonin, Nicole Kresge, Rajiv Baveja, Yukihiro Yokoyama, David Harding, Jian X. Zhang, Mark G. Clemens – 30 December 2003 – Endothelins (ET) are important regulators of the hepatic microcirculation that act through different receptor subtypes. We investigated functional significance of ETB receptors in mediating microhemodynamic effects of ETs in normal and endotoxin (lipopolysaccharide [LPS])‐primed rat liver. LPS priming (Escherichia coli O26:B6; 1 mg · kg−1) selectively increased ETB mRNA and led to a shift in available receptors to the ETB subtype.

Implication of Bcl‐2 family genes in basal and d‐amphetamine–induced apoptosis in preneoplastic and neoplastic rat liver lesions

Maria R. De Miglio, Maria R. Muroni, Maria M. Simile, Diego F. Calvisi, Paola Tolu, Luca Deiana, Angelo Carru, Gabriella Bonelli, Francesco Feo, Rosa M. Pascale – 30 December 2003 – Molecular mechanisms of basal and D‐amphetamine (AMPH)‐induced apoptosis were studied in rat liver nodules, 12 (N12) and 30 (N30) weeks after initiation, and in hepatocellular carcinoma (HCC) induced by diethylnitrosamine in rats subjected to resistant hepatocyte model. Basal apoptosis in hematoxylin/eosin– and propidium iodide–stained sections was higher in nodules and HCC than in normal livers.

If the donor had an early‐stage genitourinary carcinoma and the liver has already been implanted, should we perform the transplantectomy?

Alfonso S. Serralta, Francisco C. Orbis, Fernando R. Sanjuan, Angel H. Moya, Rafael López‐Andújar, Eugenia I. Pareja, Juan C. Vila, Manuel B. Juan, Jose P. Mir – 30 December 2003 – Information regarding the outcome of liver grafts from cadaveric donors with genitourinary cancer is scarce. In some cases, the liver has already been implanted when the tumor is detected. What must we do then? Our goal is to evaluate the outcome of recipients of liver allografts from donors with unsuspected early‐stage genitourinary carcinoma.
