Kidney allograft failure due to chronic injury/rejection remains the main cause of graft loss in renal transplant recipients (RTR). Here, we investigated whether specific biomarkers of extracellular matrix (ECM) turnover are associated with allograft function and chronic kidney disease (CKD) stage in RTR. Seventy-eight patients who attended the University Medical Center Groningen for a routine check-up after kidney transplantation were enrolled in the study. Plasma and/or 24h-urine samples were collected and specific matrix-metalloproteinase-generated neo-epitope fragments of collagens were measured by enzyme-linked immunosorbent assay...

BACKGROUND: Posttransplantation diabetes mellitus (PTDM) has been associated with inferior patient and allograft outcomes. However, previous studies didn't identify differences in infection control and alloreactivity. METHODS: We studied 449 kidney transplant recipients (KTRs) between 2005 and 2013. 50 (11.1%) KTRs were diagnosed with PTDM and 60 (13.4%) KTRs with pre-existing diabetes. Samples were collected pretransplantation, at +1, +2, +3 months posttransplantation...

BACKGROUND: Previous studies identified B cell gene signatures and predominance of specific B cell subsets as a marker of operational tolerance following kidney transplantation. These findings suggested a role for B cells in the establishment or maintenance of tolerance. Here we analyzed B cell recovery in 4 subjects, 3 of whom achieved tolerance after combined kidney/bone marrow transplantation. METHODS: Peripheral B cell subsets were examined longitudinally by flow cytometry...

Background and objective African-Americans and Hispanic-Americans with lupus are the two most common minority groups who receive kidney transplants in the USA. It is unknown if African-Americans and Hispanic-Americans with lupus have similar outcomes after kidney transplantation. In this study, we assessed whether African-Americans compared to Hispanic-Americans have worse kidney allograft survival after risk factors of rejection and other prognostic factors were matched between both groups. Methods Out of 1816 African-Americans and 901 Hispanic-Americans with lupus, who received kidney transplants between 1987 and 2006 and had complete records in the UNOS program, 478 pairs were matched in 16 baseline predictors and follow-up time employing a predicted probability of group membership...

Background Lupus nephritis (LN) is one of the most frequent complications of SLE and occurs in up to 50% of cases depending on the studied population. Of these, approximately 20% progress to end-stage renal disease (ESRD), with the treatment of choice being a kidney transplant. Objective The objective of this study was to describe the clinical outcome of patients transplanted due to LN, compared with patients transplanted for other causes, in a Latin American population from the Fundación Valle del Lili in Cali, Colombia...

BACKGROUND: Hemolytic uremic syndrome (HUS) can be triggered by Shiga toxin producing Escherichia coli (STEC) infection or it can be defined as atypical HUS (aHUS) if it is related to uncontrolled complement activation. aHUS is characterized by a high incidence of recurrence after kidney transplantation, and it can also occur de novo in transplant recipients. Eculizumab is used both to prevent and to treat aHUS following kidney transplantation. In this paper, we report our centre experience and we present 4 cases of HUS in patients who underwent kidney transplantation...

The major histocompatibility complex (MHC) class I chain-related gene A (MICA) is located centromerically to the human leukocyte antigen (HLA)-B. The short distance between these loci in the MHC indicates the presence of linkage disequilibrium (LD). Similarly to the HLA, the MICA is highly polymorphic, and this polymorphism has not been well documented in different populations. In this study, we estimated the allelic frequencies of MICA and the linkage disequilibrium with HLA-B alleles in 346 renal-transplant candidates in southern Brazil...

The genetic rs12917707-G>T variant in uromodulin (UMOD) has been associated with renal function, chronic kidney disease and hypertension with the minor T-allele showing a protective effect. Hypertension and nephrotoxicity are adverse effects of chronic cyclosporine treatment. We tested whether UMOD rs12917707-T in donor kidneys associates with long-term graft survival in 393 Caucasian patients with stable graft function for more than 10 weeks after kidney transplantation treated with a cyclosporine-based maintenance therapy (mean graft survival 9 years)...

Early detection and proper management of kidney rejection are crucial for the long-term health of a transplant recipient. Recipients are normally monitored by serum creatinine measurement and sometimes with graft biopsies. Donor-derived cell-free deoxyribonucleic acid (cfDNA) in the recipient's plasma and/or urine may be a better indicator of acute rejection. We evaluated digital PCR (dPCR) as a system for monitoring graft status using single nucleotide polymorphism (SNP)-based detection of donor DNA in plasma or urine...

The effects of CD20+ B-cell infiltration during acute rejection on graft outcomes are controversial. The objective of this systematic review and meta-analysis was to clarify this issue. We performed a systematic literature search for studies published up to January 14, 2016. A total of 5 studies, with 200 patients, were included. The presence of CD20+ B cells in renal biopsies during allograft rejection was associated with graft loss and steroid resistance. No association of CD20+ B-cell infiltration with C4d-positive staining of the peritubular capillaries in renal biopsies was found in the analysis of patients who experienced kidney graft rejection...

Rabies is usually transmitted to humans through bites of infected animals; however, it can rarely be transmitted through deceased donor organs or tissues when not suspected. Here, we report a case of rabies transmission in a child. The child was a 5-year-old girl who was admitted to the pediatric intensive care unit with encephalitis of unexplained cause 3.5 months after she received a kidney transplant from a deceased donor. The laboratory and imaging studies did not reveal any explanation for her rapidly declining clinical and neurologic condition, which ended with death 4 days after admission...

PURPOSE: To evaluate whether ultrasmall superparamagnetic iron oxide nanoparticle (USPIO)-enhanced magnetic resonance imaging (MRI) can detect allograft rejection in pediatric kidney transplant patients. PROCEDURES: The USPIO ferumoxytol has a long blood half-life and is phagocytosed by macrophages. In an IRB-approved single-center prospective clinical trial, 26 pediatric patients and adolescents (age 10-26 years) with acute allograft rejection (n = 5), non-rejecting allografts (n = 13), and normal native kidneys (n = 8) underwent multi-echo T2* fast spoiled gradient-echo (FSPGR) MRI after intravenous injection (p...

BACKGROUND There are several genes and genetic loci affecting telomere length, including hTERT gene and BICD1 gene as well as polymorphisms within chromosome 18. It has been demonstrated that the age of the donor is a negative factor associated with long-term kidney allograft function, and that post-transplant complications accelerate transplanted organ aging, thus contributing to estimated glomerular filtration rate (eGFR) decreases. The aim of this study was a joint assessment of donors' and recipients' hTERT and BICD1 genes as well as chromosome 18 polymorphisms with regard to early kidney transplantation outcomes...

Exposure of renal allografts to donor-specific antibodies activates many proinflammatory genes, resulting in antibody-mediated rejection. Simultaneous liver transplantation reduces the development of antibody-mediated rejection in renal grafts exposed to donor-specific antibodies. A study by Taner et al. in this issue of Kidney International shows this effect of the liver to involve more than simply absorbing donor-specific antibodies, with a shift in the pattern of gene expression in the kidney away from proinflammatory toward preservation of tissue function...

BACKGROUND: Mammalian target of rapamycin (mTOR) inhibitors are approved to prevent allograft rejection and control malignancy. Unfortunately, they are associated with adverse effects, such as wound healing complications that detract from more extensive use. There is a lack of prospective wound healing studies to monitor patients treated with mTOR inhibitors, such as everolimus or sirolimus, especially in nondiabetics. METHODS: Patients receiving everolimus with standard immunosuppressant therapy or standard immunosuppressant therapy without everolimus were administered 3-mm skin biopsy punch wounds in the left scapular region...

The required intensity of monitoring for antibody-mediated rejection (AMR) after of ABO-incompatible (ABOi) kidney transplantation is not clearly formulized. We retrospectively evaluated a single-center cohort of 115 ABO-incompatible (ABOi) kidney transplant recipients, of which 32% were also HLA-incompatible (ABOi/HLAi) with their donors. We used an adjusted negative binomial model to evaluate risk factors for late AMR. Using this model, we risk-stratified patients into high- and low-risk groups for the development of late AMR...

BACKGROUND: Belatacept, an inhibitor of the CD28-CD80/86 co-stimulatory pathway, allows for calcineurin-inhibitor free immunosuppressive therapy in kidney transplantation but is associated with a higher acute rejection risk than ciclosporin. Thus, no biomarker for belatacept-resistant rejection has been validated. In this randomized controlled trial, acute rejection-rate was compared between belatacept- and tacrolimus-treated patients and immunological biomarkers for acute rejection were investigated...

B cells are a group of diverse phenotype and function subsets, which can both stimulate and inhibit the immune response to an allograft. They participate in the rejection process by influencing differentiation, proliferation and effector functions of T lymphocytes. B cells injure the graft via the ADCC (antibody-dependent cellular cytotoxicity) reaction and humoral rejection through plasmocyte production of donor-specific antibodies. A converse, suppressive mode of B cells can attribute to the development of tolerance and protect the graft from rejection...

Herpesvirus infections in solid organ transplant (SOT) recipients are a significant cause of morbidity and mortality. We report a case of herpes zoster (HZ) in a kidney transplant recipient while receiving belatacept, a CTLA-4 inhibitor that prevents acute rejection. The patient presented with oropharyngolaryngeal mucosal lesions that subsequently disseminated resulting in pneumonitis and meningo-encephalitis. Very late-onset HZ can occur and can present atypically in SOT recipients. Delayed recognition and treatment may result in poor outcomes, as illustrated by this case...

There has been an upsurge of interest in xenotransplantation in recent years. This resurgence can attributed to a combination of factors. First, there has been a dramatic improvement in efficacy in several preclinical models, with maximum xenograft survival times increasing to 950 days for islets, 945 days for hearts, and 310 days for kidneys. Second, the rapid development of genome editing technology (particularly the advent of CRISPR/Cas9) has revolutionized the capacity to generate new donor pigs with multiple protective genetic modifications; what once took many years to achieve can now be performed in months, with much greater precision and scope...
