Video Education and Behavior Contract to Improve Outcomes After Renal Transplantation (VECTOR): A Randomized Controlled Trial.

Sub-optimal adherence to immunosuppressant medications reduces graft survival for kidney transplant recipients and adherence-enhancing interventions are resource and time intensive. We performed a multi-center randomized controlled trial to investigate the impact of an electronically delivered intervention on adherence. Of 203 adult kidney transplant recipients who received a de novo kidney transplant n = 173 agreed to participate (intent-to-treat population) and were randomized to the intervention (video education plus behavior contract n = 91) or the control (standard education, n = 82).

Evaluation of prior authorizations in transplant recipients at an urban institution.

Background: Increasing prior authorization (PA) requirements for immunosuppression remain a burden for solid organ transplant (SOT) recipients and transplant staff. The objective of this study was to evaluate the number of PAs required and the approval rates at an academic, urban transplant center.

Methods: This was a retrospective study of SOT recipients at the University of Illinois Hospital and Health Sciences System (UI Health) that required PAs between 11/1/2019 and 12/1/2020.

Clinical Utility of the OmniGraf Biomarker Panel in the Care of Kidney Transplant Recipients (CLARITY): Protocol for a Prospective, Multisite Observational Study.

Background: Death with a functioning allograft has become the leading category of graft loss in kidney transplant recipients at all time points. Previous analyses have demonstrated that causes of death in kidney transplant recipients are predominated by comorbidities strongly associated with immunosuppressant medications. Adverse drug events (ADEs) have been strongly associated with nonadherence, health care utilization, and graft loss; clinicians face a difficult decision on whether making immunosuppressant adjustments in the face of ADEs will improve symptomology or simply increase the risk of acute rejection.

Transplant Pharmacists' Experience With Telehealth During the COVID-19 Pandemic.

The adoption of telehealth became a necessity for healthcare organizations during the COVID-19 pandemic. Transplant pharmacists are integral members of the multi-disciplinary care team who quickly adapted application of these technologies to ensure continuity of care. To assess transplant pharmacists' experience with telehealth during the COVID-19 pandemic.

Belatacept for Simultaneous Calcineurin Inhibitor and Chronic Corticosteroid Immunosuppression Avoidance: Two-Year Results of a Prospective, Randomized Multicenter Trial.

Background And Objectives: Immunosuppressive therapy in kidney transplantation is associated with numerous toxicities. CD28-mediated T-cell costimulation blockade using belatacept may reduce long-term nephrotoxicity, compared with calcineurin inhibitor-based immunosuppression. The efficacy and safety of simultaneous calcineurin inhibitor avoidance and rapid steroid withdrawal were tested in a randomized, prospective, multicenter study.

Evaluating the conversion to extended-release tacrolimus from immediate-release tacrolimus in liver transplant recipients.

Background: A new formulation of once daily extended-release tacrolimus (LCP-tac, Envarsus XR) was approved for use in the USA for kidney transplant recipients in 2015. There are limited data regarding real-world observations with conversion to LCP-tac in liver transplant recipients.

Methods: We performed a retrospective analysis of liver transplant recipients treated with LCP-tac.

Clinical Implications of Tacrolimus Time in Therapeutic Range and Intrapatient Variability in Urban Renal Transplant Recipients Undergoing Early Corticosteroid Withdrawal.

Unlabelled: Tacrolimus demonstrates wide intrapatient and interpatient variability requiring therapeutic drug monitoring. The utility of tacrolimus time in therapeutic range (TTR) after renal transplantation (RT) under an early corticosteroid withdrawal (ECSWD) protocol is unknown. The purpose of this study is to assess the impact of tacrolimus TTR in an ECSWD RT population.

Advances in personalized medicine and noninvasive diagnostics in solid organ transplantation.

Personalized medicine has been a mainstay and in practice in transplant pharmacotherapy since the advent of the field. Decisions pertaining to the diagnosis, selection, and monitoring of transplant pharmacotherapy are aimed toward the individual, the allograft, and the overall immunologic needs of the patient. Recent advances in pharmacogenomics, noninvasive biomarkers, and artificial intelligence (AI) technologies have the promise of transforming the way we individualize treatment and monitor allograft function.

Belatacept-based immunosuppression with simultaneous calcineurin inhibitor avoidance and early corticosteroid withdrawal: A prospective, randomized multicenter trial.

Simultaneous calcineurin inhibitor avoidance (CNIA) and early corticosteroid withdrawal (ESW) have not been achieved primarily due to excessive acute rejection. This trial compared 2 belatacept-based CNIA/ESW regimens with a tacrolimus-based ESW regimen. Kidney transplant recipients were randomized to receive alemtuzumab/belatacept, rabbit anti-thymocyte globulin (rATG)/belatacept, or rATG/tacrolimus.

A randomized, open-label pharmacokinetic trial of tacrolimus extended-release dosing in obese de novo kidney transplant recipients.

Purpose: Tacrolimus extended-release (TAC-ER; Astagraf XL ) is utilized in many immunosuppressive regimens post-renal transplantation. Current dosing recommendation for the TAC-ER in renal transplant is 0.15-0.

Randomised controlled trial of a video intervention and behaviour contract to improve medication adherence after renal transplantation: the VECTOR study protocol.

Introduction: Non-adherence after kidney transplantation contributes to increased rejections, hospitalisations and healthcare expenditures. Although effective adherence interventions are sorely needed, increasing education and support to transplant recipients demands greater use of care providers' time and resources in a healthcare system that is stretched. The objective of this clinical trial is to determine the effectiveness of an electronically delivered video series and adherence behaviour contract on improving medication adherence to immunosuppressant medications.

Meeting report: Consensus recommendations for a research agenda to address immunosuppressant nonadherence in organ transplantation.

Despite advances in the field of transplantation, immunosuppressant medication nonadherence (NA) remains a primary contributor to suboptimal long-term outcomes. Due to the multidimensional and multifactorial causes of medication NA, studies to date have focused on individual differing facets or single point barriers of NA with relative success. However, these successes have not proven to be sustainable, partly due to the intense resources needed for continued viability.

Evaluation of Flexible Tacrolimus Drug Concentration Monitoring Approach in Patients Receiving Extended-Release Once-Daily Tacrolimus Tablets.

The majority of United States kidney transplant patients are treated with tacrolimus, a drug effective in preventing graft rejection, but with a narrow therapeutic range, necessitating close monitoring to avoid increased risks of transplant rejection or toxicity if the tacrolimus concentration is too low or too high, respectively. The trough drug concentration tests are time sensitive; patients treated on a twice-daily basis have blood draws exactly 12 hours after their previous dose. The schedule's rigidity causes problems for both patients and health care providers.

Results of ASERTAA, a Randomized Prospective Crossover Pharmacogenetic Study of Immediate-Release Versus Extended-Release Tacrolimus in African American Kidney Transplant Recipients.

Background: Differences in tacrolimus dosing across ancestries is partly attributable to polymorphisms in CYP3A5 genes that encode tacrolimus-metabolizing cytochrome P450 3A5 enzymes. The CYP3A5*1 allele, preponderant in African Americans, is associated with rapid metabolism, subtherapeutic concentrations, and higher dose requirements for tacrolimus, all contributing to worse outcomes. Little is known about the relationship between CYP3A5 genotype and the tacrolimus pharmacokinetic area under the curve (AUC) profile in African Americans or whether pharmacogenetic differences exist between conventional twice-daily, rapidly absorbed, immediate-release tacrolimus (IR-Tac) and once-daily extended-release tacrolimus (LifeCycle Pharma Tac [LCPT]) with a delayed absorption profile.

LCPT once-daily extended-release tacrolimus tablets versus twice-daily capsules: a pooled analysis of two phase 3 trials in important de novo and stable kidney transplant recipient subgroups.

African-American and elderly kidney transplant recipients (KTR) have increased risk for poor clinical outcomes post-transplant. Management of immunosuppression may be challenging in these patients and contribute to worse outcomes. A novel once-daily formulation of tacrolimus (LCPT) has demonstrated noninferiority, similar safety, improved bioavailability, a consistent concentration time profile, and less peak and peak-trough fluctuations vs.

Experimental protocol of a randomized controlled clinical trial investigating the effects of personalized exercise rehabilitation on kidney transplant recipients' outcomes.

Background: This randomized controlled trial (RCT) will investigate the effects of a personalized exercise rehabilitation regimen on return to work and find work rate, vascular health, functional capacity, quality of life, kidney function, and body composition in kidney transplant (KT) recipients.

Methods/design: This RCT will recruit 120 men and/or women who have had a KT to participate in a 12 month exercise intervention or control (standard clinical care only) group. The 12 month exercise intervention will consist of one-on-one, progressive exercise rehabilitation sessions twice a week, for 60 min each session.

Combined Robot-assisted Kidney Transplantation and Sleeve Gastrectomy in a Morbidly Obese Recipient.

Background: Kidney transplantation confers a well-documented survival advantage for patients with end-stage renal disease (ESRD) over dialysis, regardless of body mass index (BMI). However, obese patients with ESRD have limited access to kidney transplantation. In most transplant centers, a patient with a BMI above 35 to 40 kg/m is either completely excluded from transplantation or is required to lose weight before being considered for transplantation.

Cell population in spleens during antibody-mediated rejection: pathologic and clinical findings.

Background: In the treatment of refractory antibody-mediated rejection (AMR), splenectomy has been associated with surprisingly rapid recovery of renal function. The mechanism is still unclear.

Methods: We review 11 recipients, who underwent rescue splenectomy (RS) as a treatment of AMR within 3 months after kidney transplantation.

Living donor kidney transplantation across positive crossmatch: the University of Illinois at Chicago experience.

Background: To increase living donation for kidney transplantation, we investigated desensitization of recipients with positive crossmatch against a potential living donor.

Methods: Between June 2001 and March 2007, 57 consecutive sensitized candidates for kidney transplantation, with crossmatch positive potential living donors, were treated with various desensitization protocols. All patients received plasmapheresis every other day with intravenous immune globulin 100 mg/kg starting 1 week before the scheduled transplant.

Reported isolated pancreas rejection is associated with poor kidney outcomes in recipients of a simultaneous pancreas kidney transplant.

Background: We hypothesized that many reported and presumed isolated pancreas acute rejection episodes in simultaneous pancreas kidney patients may in fact be missed concordant kidney acute rejection episodes.

Methods: To test this hypothesis, we undertook an analysis of the Organ Procurement and Transplant Network database from 1995 to 2006 to assess the impact of reported isolated pancreas rejection on kidney allograft outcomes. The primary outcome of interest was kidney graft status beyond the first posttransplant year.

ABO incompatible renal transplantation in an HIV-seropositive patient.

To date, there have been no reports of successful ABO blood group incompatible renal transplantation in HIV patients. We describe a case of a 47-year-old African American man with end-stage renal disease secondary to HIV-induced nephropathy who underwent a live unrelated (spouse) donor ABO blood group incompatible transplant using an intravenous immunoglobulin/plasmapheresis preconditioning regimen with interleukin-2 receptor antagonist induction along with tacrolimus and mycophenolate mofetil maintenance. The postoperative course was complicated by two acute cellular rejection (Banff Ia) episodes that were successfully managed with corticosteroid boluses and the addition of corticosteroids to maintenance immunosuppression.
