Antibody-mediated rejection (ABMR) of renal allografts occurs in two forms. Type 1 ABMR results from persistence and/or a rebound of preexisting donor-specific antibodies in sensitized patients and usually occurs early post-transplantation. Type 2 ABMR is associated with de novo donor-specific antibodies and usually occurs over one year post-transplantation. It is generally accepted that types 1 and 2 also differ with regard to certain pathologic features including the frequencies of C4d positivity and concurrent cell-mediated rejection...

AIM: To explore the benefits and harms of corticosteroid (CS) minimization following renal transplantation. METHODS: CS minimization attempts to improve cardiovascular risk factors (hypertension, diabetes, dyslipidemia), to enhance growth in children, to ameliorate bone disease and to lead to better compliance with immunosuppressive agents. Nevertheless, any benefit must be carefully weighed against the reduction in net immunosuppression and the potential harm to renal allograft function and survival...

Systemic administration of autologous regulatory dendritic cells (DCreg; unpulsed or pulsed with donor antigen [Ag]), prolongs allograft survival and promotes transplant tolerance in rodents. Here, we demonstrate that nonhuman primate (NHP) monocyte-derived DCreg pre-loaded with cell membrane vesicles from allogeneic PBMC, induce T cell hyporesponsiveness to donor alloAg in vitro. These donor alloAg-pulsed autologous DCreg (1.4-3.6 x 10(6) /kg) were administered intravenously, one day before MHC-mismatched renal transplantation to rhesus monkeys treated with costimulation blockade (cytotoxic T lymphocyte Ag 4 [CTLA4] Ig) and tapered rapamycin...

BACKGROUND: Invasive fungal infections (IFIs) are an infrequent but major complication of heart-transplantation (HT). We sought to describe the epidemiology at our institution. METHODS: A prospective cohort study of 159 HT recipients was performed from June 2005 to December 2012. IFIs were defined by European Organization for Research and Treatment of Cancer/Mycoses Study Group criteria. RESULTS: By univariate analysis, Hispanic ethnicity/race was associated with IFI (P=0...

INTRODUCTION: Along with death engraftment, in recent years, antibody-mediated damage has been identified as the leading cause of loss of kidney transplants. Despite the recognition of the role of the B-lymphocyte subpopulation in the development of both tolerance and rejection, little is known about the trigger mechanisms and effectors of this humoral response. BACKGROUND: We analyzed the relationship between B lymphocyte subpopulations and levels of B-cell-activating factor (BAFF) with the histological findings in biopsies of renal transplantation...

A 40-year-old male with a long-standing history of type 1 diabetes with end-stage renal failure underwent combined kidney-pancreas (KP) transplant from a standard criteria donor. Post-operative course was uncomplicated with good primary function of both transplant grafts. Induction was with thymoglobulin and maintenance immunosuppression was with tacrolimus, mycophenolate mofetil and prednisolone. Nine weeks post-transplant, the patient developed dysfunction of both grafts. Panel reactive antibody testing revealed that the patient had developed a de novo donor-specific antibody and considering an antibody-mediated rejection the patient was treated with intravenous pulse methyl prednisone 500 mg ×3 doses, IV immunoglobulin 2 mg/kg in two divided doses, and ATG 7 mg/kg (total dose of 700 mg)...

Because calcineurin inhibitor immunosuppressive drugs (CNIs) induce arteriolar hyalinosis (ah) in kidney transplants, ah lesions can potentially provide information about drug exposure. We studied the relationship of ah lesions to findings and outcomes in 562 indication biopsies taken 3 days to 35 years post-transplant. Prevalence of ah lesions increased with time post-transplant (TxBx). Ah-scores correlated with arterial intimal thickening and atrophy-fibrosis but, unlike atrophy-fibrosis, did not increase until after 500 days because of a background of ah1 lesions in early biopsies reflecting donor aging...

BACKGROUND: Standard practice for immunosuppressive therapy after renal transplantation is quadruple therapy using antibody induction, low-dose tacrolimus, mycophenolate mofetil, and corticosteroids. Long-term steroid intake significantly increases cardiovascular risk factors with negative effects on the outcome, especially post-transplantation diabetes associated with morbidity and mortality. In this trial, we examined the efficacy and safety parameters of rapid steroid withdrawal after induction therapy with either rabbit antithymocyte globulin (rabbit ATG) or basiliximab in immunologically low-risk patients during the first year after kidney transplantation...

The two important issues affecting recipients of solid organ transplants and of importance to immunologists are (i) sensitization of the recipient to HLA antigens and the resultant humoral immune response leading to the development of anti-HLA antibodies; and ii) development of robust assays for early detection of humoral rejection post-transplant. Evidence from several studies clearly indicates that presence of circulating anti-HLA antibodies especially donor specific leads to early graft loss and high titres of DSA may even lead to hyperacute or accelerated acute rejection...

BACKGROUND: Many aspects of post-transplant monitoring of donorspecific (DSA) and non-donorspecific (nDSA) anti-HLA antibodies on renal allograft survival are still unclear. Differentiating them by their ability to bind C1q may offer a better risk assessment. METHODS: We retrospectively investigated the clinical relevance of de novo C1q-binding anti-HLA antibodies on graft outcome in 611 renal transplant recipients. Acute rejection (AR), renal function and graft survival were assessed within a mean follow-up of 6...

BACKGROUND: With the incessantly increasing number of patients on the waiting list for renal transplants, crossing the blood group barrier can substantially increase the donor pool. We started ABO-incompatible (ABOi) renal transplantation in 2013 with a relatively low-cost preconditioning protocol (additional cost, ∼$1200). This study reports the short-term outcome of ABOi renal transplantations performed at our institution. METHODS: A total of 45 adult ABOi kidney transplant recipients (KTRs) were included in the study...

The association of blood transfusions with GS after pediatric KTx is unclear. We retrospectively analyzed blood transfusions post-KTx and subsequent outcomes. Between 1984 and 2013, 482 children (<18 years of age) underwent KTx at our center. Recipient demographics, outcomes and transfusion data were collected. Cox regression with post-KTx blood transfusion as a time-dependent covariate was performed to model the impact of blood transfusion on outcomes. Of the 208 (44%) that were transfused, 39% had transfusion <1 month post-KTx; 48% >12 months...

BACKGROUND: The relationship between personality and health is frequently studied in scientific research. This study investigated the clinical/biochemical course of kidney transplant patients based on personality traits. METHODS: A longitudinal study assessed 114 kidney transplant patients (men = 68 and women = 46) with an average age of 47.72 years (SD = 11.4). Personality was evaluated using the Brazilian Factorial Personality Inventory (BFP/Big Five Model)...

BACKGROUND: Causes of "true" late kidney allograft failure remain unclear as study selection bias and limited follow-up risk incomplete representation of the spectrum. METHODS: We evaluated all unselected graft failures from 2008-2014 (n = 171; 0-36 years post-transplantation) by contemporary classification of indication biopsies "proximate" to failure, DSA assessment, clinical and biochemical data. RESULTS: The spectrum of graft failure changed markedly depending on the timing of allograft failure...

In renal transplantation, use of calcineurin inhibitors (CNIs) is associated with nephrotoxicity and immunosuppression with malignancies and infections. This trial aimed to minimize CNI exposure and total immunosuppression while maintaining efficacy. We performed a randomized controlled, open-label multicenter trial with early cyclosporine A (CsA) elimination. Patients started with basiliximab, prednisolone (P), mycophenolate sodium (MPS), and CsA. At 6 months, immunosuppression was tapered to P/CsA, P/MPS, or P/everolimus (EVL)...

Antibody-mediated rejection (ABMR) jeopardises short- and long-term transplant survival and remains a challenge in the field of organ transplantation. We report the first use of the anticomplement agent eculizumab in Oman in the treatment of a 61-year-old female patient with ABMR following a living unrelated kidney transplant. The patient was admitted to the Sultan Qaboos University Hospital in Muscat, Oman, in 2013 on the eighth day post-transplantation with serum creatinine (Cr) levels of 400 µmol/L which continued to rise, necessitating haemodialysis...

The first kidney transplantation was performed in 1951 and ever since then living donor transplantation became a more and more important solution for patients with end-stage renal disease (ESRD). Renal transplantation is a life-saving procedure. Morbidity and mortality on waiting-lists are strongly correlated with the time of dialysis and end-stage renal disease is one of the most important causes of death; this is the reason why transplantation has to be performed as soon as possible in order to reduce the time of dialysis...

BACKGROUND: The Fischer-to-Lewis (LEW) rat model of kidney transplantation is a widely accepted and well-characterized model of chronic rejection. In contrast to transplantation in a clinical setting, however, the absence of treatment with immunosuppressants and only minor mismatch of major histocompatibility complexes (MHCs) are critical discrepancies. Here, we established a rat model of chronic rejection using fully MHC-mismatched strains in which kidney disease progresses even under immunosuppressive therapy...

De novo donor-specific antibodies (dnDSAs) that develop after renal transplantation are independent predictors of allograft loss. However, it is unknown if dnDSA C1q status or titer at the time of first detection can independently predict allograft loss. In a consecutive cohort of 508 renal transplant recipients, 70 developed dnDSAs. Histologic and clinical outcomes were correlated with the C1q assay or dnDSA titer. C1q positivity correlated with dnDSA titer (p < 0.01) and mean fluorescence intensity (p < 0...

BACKGROUND: Antibody-mediated rejection (ABMR) has emerged as the leading cause of renal graft loss. The optimal treatment protocol in ABMR remains unknown. This study aimed to assess the efficacy of intravenous immunoglobulin (IVIG) for treatment of ABMR in renal recipients. METHODS: Thirty-nine ABO-compatible cross-match-negative renal recipients with biopsy-proven ABMR composed the study group. Pulses of methylprednisolone (MP) and appropriate enhancement of net state of immunosuppression were applied in all individuals; 17/39 recipients were administered IVIG (IVIG group); the remaining 22/39 patients, identified to be nonadherent or unsatisfactorily immunosuppressed, were kept on the initial treatment (MP group)...
