Hepatic artery thrombosis (HAT) is a significant cause of morbidity after liver transplantation. The aims this study are to identify and compare risk factors that might contribute HAT.A total 424 transplants performed at the University Virginia were reviewed. HAT was defined as complete disruption arterial blood flow allograft identified in 29 cases (6.8%). classified early (less than 1 month posttransplant, 9 cases: 2.1%) or late (more 20 5.4%). Possible for analyzed using Pearson chi2 test...

Abstract Background The global prevalence of diabetes is rising. Lack physical activity a known risk factor, and older adults with face higher complications compared to other age groups. Additionally, the mortality increases longer duration diabetes. Objective This study aimed investigate how meeting guidelines associated in adults. Methods We analysed data from 5679 men women (aged ≥65 years) who participated Korea National Health Nutrition Examination Survey (2016–19). Physical levels were...

Historically, age has been considered to be a relative contraindication for organ donors. The use of elderly donors liver transplantation remains controversial due the fear inferior outcome. According United Network Organ Sharing (UNOS) data, proportion older increasing annually. This study describes short‐ and long‐term outcomes donor livers. Three hundred seventy‐four primary transplantations, which had performed at University Virginia Health System from 7 February 1988 31 December 1998,...

Kidney Transplantation from a Donor Following Cardiac Death Supported with Extracorporeal Membrane OxygenationTo expand the donor pool, organ donation after cardiac death (DCD) has emerged.However, kidneys DCD donors have period of long warm ischemia between arrest and harvesting organs.Recently, we used extracorporeal membrane oxygenation (ECMO) to minimize ischemic injury during ´no touch´ periods in Maastricht category II performed two successful kidney transplantations.The were procured...

Clin Transplant 2011: 25: E647–E655. © 2011 John Wiley & Sons A/S. Abstract: Functioning nephron mass is a determinant transplant recipients. The and its weight have been reported be surrogates mass. To investigate impact ratios (BSA) within six months post-transplantation, we measured volume, using computed tomography with 3-dimensional reconstruction...

Abstract: Kidney donation from female donors to male recipients has been reported be associated with decreased allograft survival. Whether there was a gender‐related inadequacy between donor nephron supply and recipient functional demand investigated in this study. One hundred ninety‐five living kidney transplant that had neither ischemic injury, episode of rejection, nor any complication were included. Weights heights both recorded calculate body surface area, lean weight, mass index. The...

Everolimus and cyclosporine A (CsA) exhibit synergistic immunosuppressive activity when used in combination. We examined the safety efficacy of use everolimus with a cyclosporine-sparing strategy de novo renal transplant recipients.A comparative, parallel, randomized, open-label 1-year study has been performed 148 patients from five centers to compare tolerability reduced exposure CsA (the investigational group) or enteric-coated mycophenolate sodium standard-exposure control combination...

Many immunosuppressive drugs are prescribed as twice-daily dosing. A simplified once-daily dosing of drug regimen may improve medication adherence. We investigated adherence consisting extended-release tacrolimus, sirolimus, and corticosteroids along with the efficacy safety this regimen. This study was a prospective, multicenter, controlled cohort trial. Stable kidney transplant recipients who had received transplantation at least 3 months before enrollment were eligible for study....

<i>Background:</i> Previous findings have demonstrated that the expression of cytotoxic effector molecules is increased in acute rejection renal allografts. In present study, we serially examined gene perforin, granzyme B and Fas ligand (FasL) peripheral blood lymphocytes (PBLs) allograft recipients to assess potential their as a marker rejection. <i>Methods:</i> PBLs were isolated from samples taken on days 2, 4, 6, 8, 10 12 after transplantation. Competitive PCR was...

Most of the previous studies reported that tacrolimus (TAC) with sirolimus (SRL) was associated worse post-transplant outcomes in kidney transplantation, compared TAC mycophenolate mofetil (MMF). These might be attributable to high-dose SRL. However, using low-dose SRL for transplantation are uncertain. The aim this study assess efficacy and safety extended-release (ER-TAC) versus MMF ER-TAC.We randomly assigned 158 renal transplant patients receive or combination ER-TAC corticosteroid....

It is not clear whether survival in kidney transplant recipients with pre-transplant diabetes has improved over the past decades. We compared rates of mortality and major adverse cardiovascular events (MACE) after renal transplantation patients without diabetes. Furthermore, we investigated era recipient age affected association between status events.

We investigated the changing patterns of insulin secretion and resistance risk factors contributing to development post-transplant diabetes mellitus (PTDM) in kidney recipients under tacrolimus-based immunosuppression regimen during 1 year after transplantation. This was a multicenter prospective cohort study. Of 168 subjects enrolled this study, we analyzed total 87 transplant without which assessed by oral glucose tolerance test before evaluated incidence PTDM followed up index...

Abstract: Introduction: Upon analysis of the risk factors affecting renal graft survival and function, time‐dependent effects each factor should be differentiated from their net effects. To evaluate chronologically different impacts on we reviewed 390 recipients who received a kidney 1‐haplotype‐matched living‐related donors. Materials methods: Until 5‐yr post‐transplantation (TX), yearly serum creatinine (Scr), 24‐h urinary excretion protein, changes were compared by episodes acute...
