Filter by:The purpose of this study is to determine whether the endotracheal cardiac output monitor (ECOM) is accurate and predictive in liver failure patients with hyperdynamic circulatory changes.
Parts A & B: Conversion of stable pediatric allograft recipients from Prograf® immunosuppression to Advagraf® immunosuppression to compare exposure and one year follow-up for safety and efficacy. Part C: Continuation of long-term follow-up and provision of ongoing study medication to subjects to whom Advagraf® is currently not available.
The study was designed to investigate whether, compared with conventional sole perfusion with high-viscosity solution of University of Wisconsin (UW), sequential perfusion of liver grafts with low-viscosity and high-viscosity preservation solutions could further decrease the incidence of nonanastomotic biliary strictures (NAS) after liver transplantation.
To determine whether long-term maintenance therapy with a single drug (Myfortic) applied using advanced immunologic monitoring tools in selected patients can lead to superior native kidney function at 2 years without resulting in increased acute rejection episodes or deterioration of liver allograft function.
Resistance strengthening exercise will increase strength and functional activity greater than ambulation in subjects post-liver transplantation.
This open-label clinical trial will evaluate the pharmacodynamics, pharmacogenomics and early efficacy and safety of steroid-free Tacrolimus (TAC) monotherapy and its minimization after induction with rabbit, anti-human thymocyte globulin (rATG, Genzyme, Cambridge, MA) in children and adults with pediatric liver transplantation. Eighty subjects (0-21 years) receiving liver transplantation will be enrolled. Incidence and severity of biopsy-proven acute cellular rejection (ACR) is a primary endpoint as well as time to Tacrolimus whole blood concentrations <8 ng/ml The expected incidence of ACR is 50% and is derived from a non-consecutive subject population (n=40) who received an identical regimen in IND 64555. This incidence is acceptable because the long term sequel of rejection reported with other allografts have not been observed in liver grafts during IND 64555. These risks are further negated by the unique regenerative capacity of the liver allograft. An OBSERVATIONAL arm is being included in this trial. Because the numbers of pediatric liver transplants (LTx) are small in any single center setting, no information is known about relative outcomes on a conventional protocol, in children receiving conventional protocol of steroids+Tacrolimus. The PURPOSE of this additional recruitment is OBSERVATIONAL, only. Therefore, these subjects will NOT be randomized. Rather, by studying all types of patients, the investigators hope to utilize maximally, all available subjects, to understand the relative place of monotherapeutic induction. In turn, this will be the basis for a follow-up comparative, randomized trial.
Long-term immunosuppression carries potential adverse effects such as risk of infection, malignancy, renal insufficiency, diabetes and hypertension. In clinical liver transplantation, some liver transplant recipients maintain allograft function without immunosuppressive drugs. This is called as "operational tolerance". Many attempts have been made to identify immunological biomarkers predicting operational tolerant patients. Therefore, the investigators aimed to identify patients who have the potential to be operationally tolerant using biomarkers, withdraw immunosuppressant gradually and stop ultimately with monitoring of biomarkers.
We hypothesize that delayed graft function and ITBS events may be related to small blood clots (microthrombi) that collect in the kidneys and liver after cardiac death. Treatment of the DCD organs with a thrombolytic agent prior to implantation may reduce post-transplant morbidity and mortality, and may ultimately result in a greater number of transplantable livers and kidneys.
The aim of the study is to investigate the significance of intact nerve supply to the liver for the glucagon-like peptide-1 (GLP-1) induced insulin secretion. The hypothesis is that the effects of GLP-1 is transmitted through the GLP-1 receptor and that these effects involve sensory afferent neurons, probably primarily parasympathetic.
This study is being done to determine if patients receiving (iNO) will have increased liver function and less damage from IR than patients who do not receive (iNO).
