Cell-Cycle Regulatory Proteins In Podocyte Cell In Idiopathic Nephrotic Syndrome Of Childhood., Tarak Srivastava, Robert E. Garola, J M. Whiting, Uri S. Alon

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: The podocyte cell is believed to play an important role in idiopathic nephrotic syndrome (INS) of childhood. In adults with cellular and collapsing focal segmental glomerulosclerosis (FSGS), the expression of cell-cycle regulatory proteins such as p27, p57, and cyclin D is decreased and expression of cyclin A, Ki-67, and p21 is observed in podocyte cells suggestive of a dysregulated podocyte phenotype. We investigated for alterations in the expression of cyclin kinase inhibitors, p27, p57, p21, and cyclins D and A in the podocyte cell of children with INS.

METHODS: Forty-two kidney biopsies were investigated; 14 with minimal-change disease (MCD), …

Effects Of Tacrolimus On Ischemia-Reperfusion Injury., Shawn D. St Peter, Adyr A. Moss, David C. Mulligan

Manuscripts, Articles, Book Chapters and Other Papers

In addition to efficacious immunosuppression for the benefit of organ transplantation, tacrolimus has diverse actions that result in amelioration of ischemia-reperfusion injury. Knowledge is accumulating rapidly on the mechanisms through which tacrolimus exerts these cytoprotective effects, including alterations in microcirculation, free radical metabolism, calcium-activated pathways, inflammatory cascades, mitochondrial stability, apoptosis, stress-response proteins, and tissue recovery. Within the nucleus, actions mediating the effects of tacrolimus appear to be dominantly influenced by interactions with the transcription factor, nuclear factor-kappaB. Because tacrolimus is a cornerstone agent in immunosuppression regimens throughout the world and knowledge of its cellular mechanisms is evolving, it is important …

Tacrolimus As A Liver Flush Solution To Ameliorate The Effects Of Ischemia/Reperfusion Injury Following Liver Transplantation., Shawn D. St Peter, David J. Post, Manuel I. Rodriguez-Davalos, David D. Douglas, Adyr A. Moss, David C. Mulligan

Manuscripts, Articles, Book Chapters and Other Papers

The goal of this report is to evaluate in a prospective randomized fashion the effect of flushing hepatic allografts with tacrolimus before transplantation. A prospective, double-blinded, randomized trial was performed. Twenty patients receiving orthotopic liver transplants from October 2000 to October 2001 were randomized into two groups. Group 1 (active) was administered tacrolimus, 20 ng/mL, plus Plasma-lyte A (Baxter Healthcare Corp, Deerfield, IL) liver flush solution; and group 2 (placebo) was administered only Plasma-lyte A. Ischemia/reperfusion injury was assessed in both groups after transplantation by means of serum laboratory values to assess hepatocellular damage, synthetic function, and ion transport capacity. …

Optimisation Of Bile Production During Normothermic Preservation Of Porcine Livers., Charles J. Imber, Shawn D. St Peter, Inigo Lopez De Cenarruzabeitia, Hugh Lemonde, Mike Rees, Andrew Butler, Peter T. Clayton, Peter J. Friend

Manuscripts, Articles, Book Chapters and Other Papers

Machine perfusion of livers may provide a mechanism for extended preservation of marginal donor organs before transplantation, as well as a method for viability assessment. It has proved possible in a series of experimental porcine liver perfusions to maintain liver viability for up to 72 h. However, a reduction in bile production with associated histological evidence of cholestasis was seen after 10 h of perfusion, damaging the biliary canaliculi during the preservation period and leaving these organs in an unacceptable condition for transplantation. It was proposed that reduction in bile production was the result of a relentless depletion of available …

Current Practice Regarding The Use Of Fatty Livers: A Trans-Atlantic Survey., Charles J. Imber, Shawn D. St Peter, Inigo Lopez, Lynden Guiver, Peter J. Friend

Manuscripts, Articles, Book Chapters and Other Papers

A strong association exists between the presence of steatosis in a donor liver for transplantation and the development of primary nonfunction in the recipient. Despite this, appraisal of the donor remains one of the least scientific aspects of the transplantation process, and many centers base their practice on subjective opinion, rather than objective data. We conducted this survey to illuminate controversial issues and highlight the variation of opinion and practice policies both between and within the United Kingdom and the United States. A simple, anonymous, one-page, 10-question survey with tick-box answers was sent to every practicing liver transplant surgeon in …

Hepatic Steatosis And Its Relationship To Transplantation., Charles J. Imber, Shawn D. St Peter, Ashok Handa, Peter J. Friend

Manuscripts, Articles, Book Chapters and Other Papers

Fatty infiltration of the liver is common in the brain-dead donor population and has a strong correlation with primary nonfunction after cold preservation, a condition that is catastrophic to liver transplant recipients. This literature review examines factors associated with the development, diagnosis, quantification, and clinical management of this difficult condition.

Extended Preservation Of Non-Heart-Beating Donor Livers With Normothermic Machine Perfusion., Shawn D. St Peter, C J. Imber, I Lopez, D Hughes, P J. Friend

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Non-heart-beating donor (NHBD) livers represent an important organ pool, but are seldom utilized clinically and require rapid retrieval and implantation. Experimental work with oxygenated perfusion during preservation has shown promising results by recovering function in these livers. This study compared sanguinous perfusion with cold storage for extended preservation of the NHBD liver in a porcine model.

METHODS: Porcine livers were subjected to 60 min of in vivo total warm ischaemia before flushing, after which they were preserved by one of two methods: group 1 (n = 4), University of Wisconsin (UW) solution by standard cold storage for 24 h; …

Beta-Galactosidase As A Marker Of Ischemic Injury And A Mechanism For Viability Assessment In Porcine Liver Transplantation., Shawn D. St Peter, Charles J. Imber, Inigo Lopez De Cenarruzabeitia, James Mcguire, Tim James, Richard Taylor, Peter J. Friend

Manuscripts, Articles, Book Chapters and Other Papers

Glycohydrolases are a group of enzymes contained predominantly within lysosomes, which are released during Kupffer cell activation or death. One of these, beta-galactosidase, has been proposed as a marker of ischemia-reperfusion injury in the liver because Kupffer cell activation represents a primary event in the injurious reperfusion cascade. In this study, we compared B-galactosidase with more traditional indicators of liver injury and function in a porcine model of liver preservation. Porcine livers were allocated into two groups: group C (n = 5), preserved in University of Wisconsin solution by standard cold storage for 24 hours, and group W (n = …

Association Of Viral Genome With Graft Loss In Children After Cardiac Transplantation., Girish S. Shirali, J Ni, R E. Chinnock, J K. Johnston, G L. Rosenthal, N E. Bowles, J A. Towbin

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: The survival of recipients of cardiac allografts is limited by rejection, lymphoproliferative disease, and coronary vasculopathy. The purpose of this study in children who had received heart transplants was to evaluate the cardiac allografts for myocardial viral infections and to determine whether the presence of viral genome in the myocardium correlates with rejection, coronary vasculopathy, or graft loss.

METHODS: We enrolled heart-transplant recipients 1 day to 18 years old who were undergoing evaluation for possible rejection and coronary vasculopathy. Endomyocardial-biopsy specimens were evaluated for evidence of rejection with the use of standard criteria and were analyzed for the presence …

Synaptopodin Expression In Idiopathic Nephrotic Syndrome Of Childhood., Tarak Srivastava, Robert E. Garola, J M. Whiting, Uri S. Alon

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Synaptopodin is a proline-rich protein intimately associated with actin microfilaments present in the podocytes' foot processes. We investigated for synaptopodin expression in children with idiopathic nephrotic syndrome (INS), including minimal change disease (MCD), diffuse mesangial hypercellularity (DMH), and focal segmental glomerulosclerosis (FSGS); in children with congenital nephrotic syndrome of the Finnish type (CNF); and in normal kidney tissue. In particular, we examined whether an association exists between synaptopodin expression in podocyte cells and the response to steroids in INS, and whether synaptopodin expression can predict FSGS upon the initial kidney biopsy in children who progress from MCD or DMH …

Posttransplant Recoarctation Of The Aorta: A Twelve Year Experience., Girish S. Shirali, C E. Cephus, M A. Kuhn, K K. Ogata, L K. Vander Dussen, R E. Chinnock, N F. Mulla, J K. Johnston, L L. Bailey, S R. Gundry, A J. Razzouk, R L. Larsen

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVES: This study was undertaken to investigate the incidence of posttransplant recoarctation of the aorta, delineate the mode of presentation, identify risk factors that predict recoarctation and examine the results of intervention for posttransplant recoarctation.

BACKGROUND: Patients with aortic arch hypoplasia require extended arch reconstruction at transplant, with an inherent possibility of subsequent recoarctation of the aorta.

METHODS: This was a retrospective review of all children (ageyears) who underwent cardiac transplantation over a 10-year period. Collected data included pretransplant diagnosis, details of the transplant procedure and posttransplant data including development of recoarctation of the aorta, interventions for recoarctation and the …

Dobutamine Stress Echocardiography For Assessing Coronary Artery Disease After Transplantation In Children., R L. Larsen, P M. Applegate, D A. Dyar, P A. Ribeiro, S D. Fritzsche, N F. Mulla, Girish S. Shirali, M A. Kuhn, R E. Chinnock, P M. Shah

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVES: The purpose of this study was to determine the feasibility, safety and diagnostic accuracy of dobutamine stress echocardiography (DSE) for evaluating posttransplant coronary artery disease (TxCAD) in children, and to determine the frequency of selected cardiac events after normal or abnormal DSE.

BACKGROUND: Posttransplant coronary artery disease is the most common cause of graft loss (late death or retransplantation) after cardiac transplantation (CTx) in children. Coronary angiography, routinely performed to screen for TxCAD, is an invasive procedure with limited sensitivity. The efficacy of DSE for detecting atherosclerotic coronary artery disease is established, but is unknown in children after CTx. …

The Optimal Fontan Connection: A Growing Extracardiac Lateral Tunnel With Pedicled Pericardium., S R. Gundry, A J. Razzouk, M J. Del Rio, Girish S. Shirali, L L. Bailey

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: The concept of a lateral tunnel for the Fontan operation is now widely accepted. Most lateral tunnels are constructed intraatrially with the use of aortic crossclamping. Construction of extracardiac lateral tunnels with the use of homografts or other nonviable tubes eliminates aortic crossclamping but lacks growth potential in length or width. The native pericardium, which is "sealed" posteriorly along the pulmonary artery, atrium, and inferior vena cava, could be turned down onto the right atrium to form a viable extracardiac lateral tunnel.

METHODS: We designed and successfully constructed extracardiac lateral tunnels using viable autologous pericardium, pedicled on its lateral …

Ventricular Remodeling Following Infant-Pediatric Cardiac Transplantation. Does Age At Transplantation Or Size Disparity Matter?, Girish S. Shirali, F Lombano, W L. Beeson, D A. Dyar, N F. Mulla, A Khan, J K. Johnston, R E. Chinnock, S R. Gundry, A J. Razzouk

Manuscripts, Articles, Book Chapters and Other Papers

Early left ventricular (LV) remodeling following pediatric cardiac transplantation has not been described. To identify patterns and determinants of change in left ventricular mass and volume posttransplant, we studied 125 consecutive children who underwent cardiac transplantation between January 1, 1989 and July 31, 1993. Two-dimensional imaging-directed M-mode echocardiograms were studied weekly until 26 weeks post-transplant. LV mass and volume (indexed to BSA1.5) were measured. LV mass index increased until 3 weeks post-transplant, and then decreased. The mean decrement in LV mass index after 8 weeks post-transplant (relative to baseline) was significantly larger in patients with donor-recipient weight ratio > 1.5 compared …
