Preformed and de novo donor specific antibodies (pDSA and dnDSA) are risk factors for ABMR. This study compares the effects of pDSA vs dnDSA in pediatric kidney transplant recipients. Sixteen pediatric patients with biopsy-proven ABMR were evaluated. Strong DSA (MFI >10 000) was recorded at transplant, rejection, and follow-up. DSAs with the highest MFI were termed iDSAs. Allograft biopsies were scored according to Banff 2013 criteria. Seven of 16 (44%) patients had pDSA at transplant; 9 (56%) developed dnDSA...

Stem cells derived from oral tissue represent a highly attractive alternative source for clinical bone regeneration because they can be collected by non-invasive or minimally invasive procedures. Herein, we describe the human dental stem cells (DSCs) deriving from buccal fat pads (BFP), dental pulp (DP) of impacted teeth, and periodontal ligaments (PDL) to obtain BFPSCs, DPSCs, and PDLSCs, respectively. Cells were purified with selected medium and expanded through passages in stem cell culture medium. Purified cells were characterized for stemness by their growth rate, immunostaining, and multilineage differentiation ability...

The study of calcineurin inhibitor (CNI) blood level variability to evaluate adherence in transplantation has improved over the years. The aim of our study was to assess factors associated with this variability using the coefficient of variation (CV). A cross-sectional sample of kidney recipients grafted for more than 1 year was recruited. We recorded clinical data, data from a clinical pharmacist interview and from 6 questionnaires measuring adherence, satisfaction, behaviours, beliefs, perception of the illness and social vulnerability...

This study assessed adherence to prolonged-release tacrolimus (PR-T)-based immunosuppression during routine maintenance of renal transplant recipients in Germany. Patients had received PR-T for ≥1 month at inclusion. Data were collected during four visits (V): baseline (V1), 6 (V2), 12 (V3) and 18 (V4) months. Composite primary endpoint: non-adherence at V4, defined as self-reported non-adherence on the Basel Assessment of Adherence with Immunosuppressive Medication Scale (BAASIS©), investigator-rated non-adherence, and/or V4 tacrolimus trough level outside a pre-defined range...

Embryonic stem cell (ESC) differentiation can be used to model development and to produce transplantable cells of the desired phenotype. ESCs can reproducibly generate retinal cells but the derivation of photoreceptor precursors is variable and depends on an array of exogenous factors and intrinsic cell-cell interactions. In this work, we have defined the use of exogenous signaling factors, dissociation, and adherent versus 3-dimensional (3D) conditions on the derivation of retinal cells from pluripotent mouse ESCs...

BACKGROUND: Immunosuppression non-adherence in kidney transplant recipients (KTRs) not only increases the risk of medical intervention due to acute rejection and graft loss but burdens the socioeconomic system in the form of increased healthcare costs. An aggressive preemptive effort by healthcare professionals, geared to ensure adherence to immunosuppressants in KTRs, is significant and imperative. METHODS/DESIGN: This study was designed as a prospective, open-label, multicenter, randomized controlled study aimed at evaluating the efficacy and stability of an information and communication technology (ICT)-based centralized monitoring system in boosting medication adherence in KTRs...

MLVI has been used to assess adherence. To determine the MLVI in children <12 years of age at transplantation and to identify demographic correlates and consequences for the graft. This is a retrospective study of 50 outpatients (4.0 ± 3.5 years), at least 13-month post-liver transplantation. The outcomes evaluated were MLVI, ALT > 60 IU/L, ACR, death, and graft loss. We analyzed demographic and socioeconomic characteristics, indication for transplantation, and type of donor. Student's t test and the chi-square test were used...

The prevalence of both bipolar disorder and schizophrenia is around 1-4% in the general population and represents a relative contraindication for kidney transplantation. There are several reasons for this, including concerns in relation to relapse of psychiatric illness, medication and other post-transplant treatment non-adherence, inadequate social support, emotional and cognitive capability, and potential drug interactions between psychotropic and immunosuppressant medications. Only a small proportion of recipients with psychotic disorder has eventually been transplanted...

Calcineurin inhibitor immunosuppressive drugs induce changes such as arteriolar hyalinosis (ah) in kidney transplants, raising the possibility that molecular changes in biopsies related to histologic ah can provide information about drug exposure. We hypothesized that molecular changes associated with less-than expected hyalinosis might highlight a subpopulation of patients with under-immunosuppression/non-adherence at intermediate times post-transplant (TxBx). Using gene expression data from 562 indication biopsies, we developed a molecular classifier for predicting the expected ah lesions (Mah ) at a particular TxBx...

Medication adherence is an important determinant of transplant outcomes. Attempts to investigate adherence are frequently undermined by selection bias: It is very hard to recruit and retain non-adherent patients in research efforts. This manuscript presents recruitment strategies and results from the MALT (Medication Adherence in children who had a Liver Transplant) multisite prospective cohort study. MALT sites recruited 400 pediatric liver transplant patients who agreed to be followed for 2 years. The primary purpose was to determine whether a marker of adherence, the Medication Level Variability Index (MLVI), predicts rejection outcomes...

BACKGROUND: The majority of kidney transplants are performed in recipients (RTR) over 50; simultaneously their life expectancy is improving. The increasing age and number of RTR is likely to be paralleled by an increase of prostate cancer (PCa) incidence. However, little is known on the optimal management of these patients who represent a therapeutic challenge due to medical and anatomical graft-related issues. METHODS: AMED, Medline and Embase were searched until November 17(th) , 2016 adhering to the PRISMA guidelines and the AMSTAR checklist to investigate oncological and functional outcomes of PCa treatment in RTR...

BACKGROUND: Clinical quality registries (CQRs) are playing an increasingly important role in improving health outcomes and reducing health care costs. CQRs are established with the purpose of monitoring quality of care, providing feedback, benchmarking performance, describing pattern of treatment, reducing variation and as a tool for conducting research. OBJECTIVES: To synthesise the impact of clinical quality registries (CQRs) as an 'intervention' on (I) mortality/survival; (II) measures of outcome that reflect a process or outcome of health care; (III) health care utilisation; and (IV) healthcare-related costs...

BACKGROUND: Neuropathic or neurogenic bladder describes a process of dysfunctional voiding as the result of injury in the brain, spinal cord or nerves innervating the bladder. People with neuropathic bladder, such as from spinal cord injury (SCI), are at significant risk of morbidity from urinary tract infections (UTI). Effective methods to prevent UTI in people with SCI have been sought for many years. Probiotics (micro-organisms that exert beneficial health effects in the host) have been recommended for bacterial interference of the urological tract to reduce colonisation by uropathogen and to manage the dual problems of infection and antibiotic resistance...

Renal transplantation is now a viable alternative for dialysis in HIV-infected patients who achieve good immunovirological control with current antiretroviral therapy regimens available. However, there are few studies that analyze the incidence of post-transplant infections in this population. In this study, a retrospective analysis of data files of 24 HIV-infected kidney transplant (KT) recipients was undertaken, matched to 21 non-infected controls. All patients received induction with anti-interleukin-2 antibodies and were followed in the Pitié-Salpêtrière Hospital in Paris, France...

BACKGROUND: Follow-up care after kidney transplantation is performed in transplant centers as well as in local nephrologist's practices in Germany. However, organized integrated care of these different sectors of the German health care system is missing. This organizational deficit as well as non-adherence of kidney recipients and longterm cardiovascular complications are major reasons for an impaired patient and graft survival. METHODS: The KTx360° study is supported by a grant from the Federal Joint Committee of the Federal Republic of Germany...

Patient-identified barriers to immunosuppressive medications are associated with poor adherence and negative clinical outcomes in transplant patients. Assessment of adherence barriers is not part of routine post-transplant care, and studies regarding implementing such a process in a reliable way are lacking. Using the Model for Improvement and PDSA cycles, we implemented a system to identify adherence barriers, including patient-centered design of a barriers assessment tool, identification of eligible patients, clear roles for clinic staff, and creating a culture of non-judgmental discussion around adherence...

BACKGROUND: Psychosocial factors are useful predictors of adverse outcomes after solid organ transplantation. Although depression is a known predictor of poor outcomes in patients who undergo orthotopic heart transplantation (OHT) and is actively screened for during pre-transplant evaluation, the effects of early identification of this entity on post-transplant outcomes are not clearly understood. The purpose of this study was to evaluate the impact of pre-transplant depression on outcomes after OHT...
