Short-term (1-year) results of renal transplantation are now excellent (over 95%). Long-term (10-year and longer) results are, however, still disappointing. Where most research has focused on immunosuppression and infections, the investigators hypothesize that due to poor homeostatic capacity and necessary use of immunosuppressive and other drugs, renal transplant recipients are much more susceptible to poor dietary habits and exposure to potentially toxic contaminants than people of the general population, and that this contributes to accelerated function loss of the graft and excess risk of premature mortality, both contributing to poor long-term results. This study is a biobank and cohort study which investigates this hypothesis.
The purpose of this work was to study the incidence, types, risk factors and causative organisms of bacterial infections in HCV Egyptian patients following Liver Transplantation. Moreover, to identify the emerging resistant strains and their proper antimicrobial therapy
This study involves sampling bone marrow transplant patients, hospital workers and the patient room for microbes using swabs and other techniques. We send these samples to the laboratory, where they will use state-of-the art technology to identify and relate the microbes to each other. This study also involves putting copper, nickel, or titanium into some hospital rooms, and seeing whether these metals influences the growth of microbes. Some equipment in the hospital room, such as faucets and soap dispensers will be replaced by sensor-based (e.g. touchless) controls.
This is a clincial validation study of a dried blood spot (DBS) method for the analysis of immunosuppressive and antifungal agents currently subject of therapeutic drug monitoring (TDM) in a pediatric population. The primary goal is to clinically validate a finger prick DBS method compared to conventional venous sampling for the analysis of 5 immunosuppressive and 4 azole antifungal drugs in the pediatric population. Secondairy goals include feasibility of the finger prick DBS method in the target population, to design an inventory of costs that will be incurred in future health-economic analyses and to construct a population PK model based on the available data collected for the primariy goal.
Cytomegalovirus (CMV) infection is the most frequent opportunistic viral infection after transplantation. It is associated with an increased incidence of acute rejection and lower graft and patient survivals. The goal of this study is to demonstrate that an immunosuppressive regimen associating everolimus and reduced dose of cyclosporine A can prevent acute rejection episodes as efficiently as standard regimen but also efficiently reduce the incidence of CMV infection at 6 months post-transplantation.
The purpose of this study is to understand the role of specific B cells in activating or repressing an anti-allograft immune response after kidney transplantation. In this study, blood will be collected from kidney transplant patients during different timepoints, prior to and after their transplant. Knowledge gained from study findings will be used to develop therapeutic strategies to prevent antibody-mediated rejection, which is a major cause of long-term graft loss in kidney transplant patients.
This is a 12-month single center, randomized, open-label, single center study designed to compare the safety and efficacy of everolimus and very low dose tacrolimus versus enteric-coated sodium mycophenolate and low tacrolimus exposure in de novo kidney transplant recipients. The purpose of this study is to compare safety and efficacy of two immunosuppressive regimens based on low tacrolimus exposure combined to everolimus or to enteric-coated mycophenolate sodium (EC-MPS) in de novo kidney transplant recipients.
The goal of this clinical research study is to learn if it is safe and feasible to transplant patients with one of two units of cord blood that has been changed in the laboratory before it is given. Only patients with leukemia, lymphoma or myelodysplastic syndrome will be allowed on this study. The secondary goal is to obtain the preliminary efficacy outcome. Researchers also want to learn if using cord blood that has been changed can help to control the disease. One cord blood unit will not be changed before it is administered to you. The cord blood unit that will be altered will be changed to use sugar that is found in small amounts in blood cells. It plays a role in telling transplanted cells where they should go in the body. Adding more sugars to the cord blood cells in the laboratory helps the cord blood cells find their way to the bone marrow faster. This process is called fucosylation. "Conditioning" is the chemo and other medicines and will be given to patients to prepare to receive cord blood transplant cells. This prevents immune system from rejecting the cells. Conditioning will be started before the transplant. ATG is a protein that removes immune cells that cause damage to the body. Clofarabine is designed to interfere with the growth and development of cancer cells. Fludarabine is designed to interfere with the DNA of cancer cells, which may cause the cancer cells to die. This chemotherapy is also designed to block your body's ability to reject the donor's bone marrow cells. Melphalan and busulfan are designed to bind to the DNA of cells, which may cause cancer cells to die. MMF and tacrolimus are designed to block the donor cells from growing and spreading in a way that could cause graft versus host disease (GVHD -- a condition in which transplanted tissue attacks the recipient's body). This may help to prevent GVHD. Rituximab is designed to attach to cancer cells, which may cause them to die. A Phase I study for treatment of patients (N=25) with hematologic malignancies and MDS who are candidates for dual-cord UCBT is ongoing at M.D. Anderson Cancer Center under an Investigator-initiated IND Application, E.J. Shpall, MD, PI. Since August, 2012, Preliminary results indicate that ASC-101 UCBT is well-tolerated and no ASC-101 related untoward adverse events have been observed. To date, the median time to neutrophil engraftment (N=9) is 15 days, and the median time to platelet engraftment (N=9) is 33 days. The trial remains ongoing.
Our study will compare all kidney transplant recipients receiving valganciclovir vs. valacyclovir for one year following kidney transplant and compare: 1. the incidence, magnitude and duration of CMV and EBV viremia in the first year after transplant. 2. the side effects of the anti-viral drugs requiring dose reduction or cessation In addition, we will test renal tissue obtained from any biopsies post-transplant (surveillance or clinically indicated biopsies) by both polymerase chain reaction (PCR) and fluorescence in situ hybridization to assess for latent CMV and/or EBV.
