We confirmed the significant effects of CYP3A5 polymorphism on the achievement of target tacrolimus trough levels and the development of acute rejection in early period after transplantation and consequent renal allograft function.

There has been a significant growth in the number of deceased donors in Korea since the appropriate deceased organ donation system was launched. A comprehensive national program is required to improve deceased donation and achieve self-sufficiency.

This study analyzed the association between medication adherence and the intrapatient variability (IPV) of tacrolimus concentrations among kidney transplant recipients through a post hoc analysis of the dataset from a recently conducted randomized controlled trial. Among 138 patients enrolled in the original trial, 92 patients with ≥ 5 months of medication event monitoring system (MEMS) use and ≥ 4 tacrolimus trough values were included in this post hoc analysis. The variability of tacrolimus tr

Engineering three-dimensional (3D) implantable tissue constructs is a promising strategy for replacing damaged or diseased tissues and organs with functional replacements. However, the efficient vascularization of new 3D organs is a major scientific and technical challenge since large tissue constructs or organs require a constant blood supply to survive in vivo. Current approaches to solving this problem generally fall into the following three major categories: (a) cell-based, (b) angiogenic fa

Background and objectives Use of arteriovenous fistulas, the most preferred type of access for hemodialysis, is limited by their high maturation failure rate. The aim of this study was to assess whether aggressive surveillance with routine duplex ultrasound and intervention can decrease the maturation failure rate of arteriovenous fistulas. Design, setting, participants, & measurements We conducted a single–center, parallel–group, randomized, controlled trial of patients undergoing autogenou

Background. High intrapatient variability (IPV) of tacrolimus (Tac) is increasingly recognized as a risk factor for poor graft outcomes in kidney transplantation. The timing of onset of its impact on kidney histologic lesions has not been investigated. Methods. We analyzed the adverse effect of Tac IPV using the coefficient of variability from 6 to 12 months posttransplantation on long-term outcomes in a cohort of 671 kidney recipients and on the evolution of chronic histologic lesions in a coho

BACKGROUND: There is a growing concern about the therapeutic equivalence of the generic tacrolimus formulation (GEN Tacrolimus) to the reference tacrolimus (REF Tacrolimus) in solid organ transplantation. METHODS: A prospective, randomized study of 126 de novo renal transplant patients was conducted to compare the efficacy, safety and pharmacokinetic (PK) profiles between GEN tacrolimus (n = 63) and REF tacrolimus (n = 63). The PK of tacrolimus was evaluated on Day 10 and 6 months under steady-s

Continuous efforts have been made by the organ donation and transplantation community in Korea to increase organ donation by the deceased. The authors detailed trends of organ donation and utilization over the past 10 yr using data provided by the KONOS. The yearly number of deceased donors has grown gradually since 2003. The number and percentage of old donors (> or = 50 yr) and donors dying from intracranial hemorrhage has increased continuously. Therefore, the percentage of standard criteria

In addition to CD4+CD25+Foxp3+ regulatory T (T(reg)) cells which protect against autoimmune tissue injury, IL-17-producing CD4+ T (T(h)17) cells have been recently described and shown to play a crucial role in autoimmune injury. It appears that there is a reciprocal developmental pathway between T(h)17 and T(reg) cells. Although IL-17 is known to be associated with allograft rejection, the cellular source of IL-17 and the nature of T(h)17 in the context of allograft rejection remain unknown. In
