BACKGROUND Acute allograft rejection remains an important cause of morbidity after kidney transplantation, and has been shown to be a crucial determinant of long-term graft function. Although rejection is mediated by recipient lymphocytes, both donor and recipient factors contribute to the local environment that influences the nature, severity, and duration(More)
BACKGROUND Acute allograft rejection remains an important cause of morbidity after kidney transplantation, and has been shown to be a crucial determinant of long-term graft function. As cytokines are major regulators of the immune system, genetic variation in cytokine production or activity may influence susceptibility to acute rejection. This study sought(More)
Liver transplantation is the treatment of choice for many patients with acute and chronic liver failure, but its application is limited by a shortage of donor organs. Donor organ shortage is the principal cause of increasing waiting lists, and a number of patients die while awaiting transplantation. Non-heart-beating donor (NHBD) livers are a potential(More)
Central venous catheters (CVCs) are commonly used in clinical practice. One of the foremost complications associated with their use is the potential for symptomatic or asymptomatic thrombosis. CVC thrombosis, in turn, may not only result in vascular and catheter occlusion but also infection, pulmonary embolism, and formation of right heart thromboemboli.(More)
BACKGROUND Chronic allograft failure (CAF) is a major cause of late graft loss in renal transplantation. Up-regulation of adhesion molecules has been demonstrated in renal allograft biopsies during both acute and chronic rejection, and these molecules are known to regulate leukocyte migration into the graft. METHODS A single-center retrospective study was(More)
BACKGROUND It is widely recognized that living-related donor (LRD) renal allografts have a higher overall graft survival than cadaver donor transplants. We tested the hypothesis that part of this is attributable to LRD kidneys being obtained under optimal conditions from healthy donors, whereas cadaveric kidneys may have experienced injury as a result of(More)
BACKGROUND Ischemia/reperfusion injury of human renal allografts has a number of clinically significant consequences. A number of mechanisms of ischemia/ reperfusion injury have been elucidated, and there is evidence that apoptosis may be a contributing factor. METHODS To examine immediate posttransplant events, fixed tissue sections from(More)
Delayed graft function (DGF) and acute rejection have both been associated with reduced renal allograft survival. In some studies, they have been shown to have an interactive effect. We studied the risk factors for DGF and the relative impact of DGF and rejection on both short- and long-term survival in recipients of cadaveric renal transplants. Data from(More)
PURPOSE Central venous catheters (CVC) are commonly used in critical care. While thrombosis is a well-recognized and frequent complication associated with their use, CVC-related thromboembolic complications, including pulmonary embolism (PE) and right heart thromboembolism (RHTE), occur less frequently and often evade diagnosis. Little information exists to(More)
Organ preservation aims to provide a viable graft with primary function post-transplant. The current basis of preservation for transplantation is static cold storage using specific preservation solutions which minimise cellular swelling and membrane pump activity, thus maintaining cellular ATP levels. The current organ shortage and consequent expansion of(More)
