Filter by:100 ambulatory cirrhotic patients attending a liver transplant clinic will undergo a comprehensive clinical evaluation for severity of liver disease, anemia, depression, and fatigue. Fatigue will be assessed with the FIS and sub-maximal exercise capacity with the 6-minute walk test (6MWT), a standardized exercise test that measures the distance that a patient is capable of walking in 6 minutes (6MWD). Depression will be assessed by using three well-known questionnaires. The SF-36, Beck's Depression Inventory (BDI-II), EQ-5D, and the Psychological General Well-Being Index (PGWBI). Univariate analysis will be performed to select the factors that potentially are associated with the scores as indicated by a P value <.20; the selected factors will then be entered in a stepwise regression to create a multivariate model giving the combination of factors that are significantly associated with the measure of fatigue and depression. Hemoglobin (Hb) levels will then be added to the model in order to test its significance while controlling for the other factors.
To search for suitable pharmacodynamic biomarkers, i.e., with high specificity for calcineurin inhibition and most affected by inter-individual variability, our works aimed at exploring the pharmacodynamics of CNI, the strength and variability of signal translation along the calcineurin pathway, as well as the steps where sources of internal (genetic) or external variability are the most influential. In order to achieve this, we assessed simultaneously NFAT1 translocation into the nucleus of peripheral blood mononuclear cells (PBMC) (NFTA1 being the main NAFT isoform in resting and activated lymphocytes), the intracellular expression of IL-2 in CD3+, CD4+ and CD8+ T cell subsets and the membrane expression of CD25 (IL-2Rα), a surface marker of T cells activation, in T cells at large. A non-interventional clinical trial was set up in healthy volunteers, patients registered on a liver transplantation waiting list (WLP) and liver transplant recipients (LTR). A different question was addressed in each group: The healthy volunteer study (n=35): explored TAC PD along the calcineurin pathway by exposing PBMC ex-vivo; modelled signal translation along this cascade; examined the interindividual variability of TAC PD parameters; and investigated the sources of the variability observed and their contribution at each step of the calcineurin pathway. Furthermore, it allowed us to evaluate the analytical variability of our techniques as well as the intra-individual variability of TAC PD parameters. WLP (n=19) were enrolled to confirm in patients with liver diseases the results obtained in healthy volunteers, as well as to test the potential influence of their initial disease on the ex-vivo pharmacodynamics of TAC. The aims of the transversal study of LTR on CNI (n=80) were to further explore the interindividual variability in the PD of CNI in realistic clinical conditions, i.e. in situations of residual PD activities under tacrolimus or cyclosporine exposure, and the potential pharmacogenetic (PG) sources of such variability. The (still small) group of liver transplant patients (n=9) enrolled immediately before transplantation and followed-up with serial monitoring along the first year post-transplantation was intended to explore the relationships between CNI PD and clinical responses.
The purpose of this study is to understand mechanisms associated with the development of coma during hepatic failure. As of today, those mechanisms are not understood and it is difficult to intervene and prevent coma development which is often associated with mortality. Understanding the mechanism involved, may allow us to prevent coma and develop new therapies to treat this disease.
Patients with compensated chronic liver disease who have an episode of acute deterioration of liver function (acute-on-chronic liver failure) are known to have up to 90% mortality rate. Hepa Wash(R) is a newly developed liver and renal support system that is based on the use of recycled albumin dialysate. The new system has shown a high detoxification capacity in in-vitro and preclinical studies. The aim of the study is to evaluate the safety and efficacy of the Hepa Wash system in patients with acute-on-chronic liver failure in the intensive care unit.
The objective of this study is to compare the effects of two liver transplant immunosuppression regimens on renal function. Patients receiving the standard combination of prednisone and high-dose tacrolimus, a drug with known nephrotoxicity (Arm A) will be compared to patients receiving prednisone, low-dose tacrolimus and mycophenolate mofetil (MMF) (Arm B). MMF is an immunosuppression agent that has no associated nephrotoxicity. The primary end point of the study will be renal function as measured by glomerular filtration rate (GFR). Thirty pediatric liver transplant recipients will be randomized to these two arms in a 1:1 ratio (i.e. 15 patients in each group). Secondary end points will measure patient and graft outcome and incidence of immunosuppression-related complications, including: neurotoxicity, diabetes mellitus, growth retardation, vomiting, diarrhea, gastrointestinal hemorrhage, thrombocytopenia, anemia, leukopenia, acute or chronic liver graft rejection, posttransplant lymphoproliferative disease (PTLD), viral infections, fungal infections and bacterial infections.
The purpose of this study is to compare the use of HepeX-B versus HBIg, two anti-viral drugs, in patients who have received liver transplants due to liver failure caused by Hepatitis B infection. Patients will be evaluated over a 6 month to 1.5 year period to evaluate whether or not the drugs prevent the Hepatitis B virus from infecting the new liver.
