Ulcero-haemorrhagic rectocolitis can occur after liver transplantation for sclerosing cholangitis. Total colectomy with or without proctectomy may be indicated in case of chronic drug-resistant colitis, dysplasia or cancer. Today, laparoscopic approach is the standard for such procedure in non-operated patients. We performed a completely laparoscopic total colectomy 5 years after a liver transplantation. There were a few peritoneal adherences, and we could safely perform the procedure almost as usual. It provided all the advantages of the laparoscopic approach in the post-operative course...

OBJECTIVES: It is known that transition, as a shift of care, marks a vulnerable phase in the adolescents' lives with an increased risk for non-adherence and allograft failure. Still, the transition process of adolescents and young adults living with a kidney transplant in Germany is not well defined. The present research aims to assess transition-relevant structures for this group of young people. Special attention is paid to the timing of the process. SETTING: In an observational study, we visited 21 departments of paediatric nephrology in Germany...

Cells can communicate via exosomes, ~100-nm extracellular vesicles (EVs) that contain proteins, lipids, and nucleic acids. Non-adherent/mesenchymal mammary epithelial cell (NAMEC)-derived extracellular vesicles can be isolated from NAMEC medium via differential ultracentrifugation. Based on their density, EVs can be purified via ultracentrifugation at 110,000 x g. The EV preparation from ultracentrifugation can be further separated using a continuous density gradient to prevent contamination with soluble proteins...

Chronic allograft injury (CAI) remains one of the biggest challenges in transplantation as it directly affects the long-term allograft survival, an area in which the scientific and transplantation communities have struggled to improve outcomes. Therefore, understanding the mechanisms of CAI is paramount to implement preventive measures and novel therapeutic options. In this review, we will address the latest evidence on CAI, potential etiologies and risk factors including non-adherence, antibody-mediated rejection, recurrence of glomerular disease, BK nephropathy, and calcineurin nephrotoxicity...

BACKGROUND: Basic and translational research supports beneficial effects of statins on bone metabolism. Clinical studies suggest that statin use may reduce the risk of hip fractures in the general population. Whether statin use is associated with hip fracture risk in kidney transplant recipients, a particularly high-risk group for this outcome, is unknown. METHODS: From the U.S. Renal Data System (2007-2011), we identified all hip fracture events recorded in Medicare billing claims of first-time kidney transplant recipients...

BACKGROUND: Annual visits with a primary care provider (PCP) are recommended for living kidney donors to monitor long-term health post-donation, yet adherence to this recommendation is unknown. METHODS: We surveyed 1170 living donors from our center from 1970-2012 to ascertain frequency of PCP visits pre- and post-donation. Interviews occurred median (IQR) 6.6 (3.8 - 11.0) years post-transplant. We used multivariate logistic regression to examine associations between donor characteristics and PCP visit frequency...

AIM: To develop a locally adapted, patient-focused transition-program, we evaluated the perceptions of adult and adolescent patients and parents regarding transition-programs and transfer. METHODS: We evaluated these perceptions by analyzing the responses of pre-transfer adolescents (n = 57), their parents (n = 57) and post-transfer adults (n = 138) from a cohort of pediatric-liver-transplant-patients using a self-designed questionnaire. Furthermore, we compared a responder group with a non-responder group as well as the provided answers with baseline characteristics and clinical outcomes to exclude selection bias, characterize high-risk patients for non-adherence and test for gender differences...

BACKGROUND: Different measures of non-adherence to immunosuppressant (IS) medication have been found to be associated with rejection episodes after successful transplantation. The aim of the current study was to investigate whether graft rejection after renal transplantation is associated with patient-reported IS medication non-adherence and IS trough level variables (IS trough level variability and percentage of sub-therapeutic IS trough levels). METHODS: Patient-reported non-adherence, IS trough level variability, percentage of sub-therapeutic IS trough levels, and acute biopsy-proven late allograft rejections were assessed in 267 adult renal transplant recipients who were ≥12 months post-transplantation...

REVIEW
Elizabeth A Steinberg, Mary Moss, Cindy L Buchanan, Jens Goebel
Non-adherence remains a significant problem among pediatric (and adult) renal transplant recipients. Non-adherence among solid organ transplant recipients results in US$15-100 million annual costs. Estimates of non-adherence range from 30 to 70% among pediatric patients. Research demonstrates that a 10% decrement in adherence is associated with 8% higher hazard of graft failure and mortality. Focus has begun to shift from patient factors that impact adherence to the contributing healthcare and systems factors...

BACKGROUND: Recipient adolescent age for non-lung solid-organ transplantation is associated with higher rates of rejection, graft loss and mortality. Although there have been no studies specifically examining adolescent outcomes after lung transplantation (LTx), limited data from the International Society of Heart and Lung Transplantation (ISHLT) Registry suggest that a similar association may exist. Recently, adolescence has been defined as 10 to 24 years of age, taking into account the biologic and sociologic transitions that occur during this age interval...

Controversy exists as to whether African American (AA) transplant recipients are at risk for developing de novo donor-specific anti-human leucocyte antigen (HLA) antibody (dnDSA). We studied 341 HLA-mismatched, primary renal allograft recipients who were consecutively transplanted between 3/1999 and 12/2010. Sera were collected sequentially pre- and post-transplant and tested for anti-HLA immunoglobulin G (IgG) via single antigen bead assay. Of the 341 transplant patients (225 AA and 116 non-AA), 107 developed dnDSA at a median of 9...

Few studies have identified the psychosocial characteristics of those children and their families associated with future non-adherence to immunosuppressive medications following a heart or lung transplant. UNOS data and medical records information were used to test the association between patient and family psychosocial characteristics and medication adherence. Medication adherence outcomes were obtained using the physician assessments in the UNOS data and measured through patient-level standard deviation scores of immunosuppressive medication blood levels...

There is a high risk for the survival of patients with an end-stage renal disease for kidney transplantation. To avoid rejection by strict medication adherence is of utmost importance to avoid the failure of a kidney transplant. It is imperative to develop non-invasive biomarkers to assess immunity risk, and to ultimately provide guidance for therapeutic decision-making following kidney transplantation. Urine biomarkers may represent the promising non-invasive tools that will help in predicting risk or success rates of kidney transplantations...

Regardless of recipient age at kidney transplantation (KTx), patients are at greatest risk for graft loss in adolescence, partly due to nonadherence to an oral immunosuppressive regimen. Belatacept, a non-nephrotoxic, first-in-class immunosuppressant that inhibits costimulation of T cells requires intravenous application only every 4 weeks, potentially leading to better adherence. However, it is only approved for use in adults. We report here the findings of the first study of belatacept in adolescents, comprising all patients in our department switched to belatacept post-KTx...

Neural stem cells (NSCs) have high translational potential in transplantation therapies for neural repair. Enhancement of their therapeutic capacity by genetic engineering is an important goal for regenerative neurology. Magnetic nanoparticles (MNPs) are major non-viral vectors for safe bioengineering of NSCs, offering critical translational benefits over viral vectors, including safety, scalability, and ease of use. This unit describes protocols for the production of suspension (neurosphere) and adherent (monolayer) murine NSC cultures...
