The development of donor-specific HLA antibodies (DSA) is associated with worse renal allograft survival in adult patients. This study assessed the natural history of de novo DSA, and its impact on renal function in pediatric renal transplant recipients (RTR). HLA antibodies were measured prospectively using single-antigen-bead assays at 1, 3, 6 and 12(More)
Graft survival seems to be worse in positive cross-match (HLAi) than in ABO-incompatible (ABOi) transplantation. However, it is not entirely clear why these differences exist. Sixty-nine ABOi, 27 HLAi and 10 combined ABOi+HLAi patients were included in this retrospective study, to determine whether the frequency, severity and the outcome of active(More)
Standard leucodepleted blood transfusions can induce the production of human leukocyte antigen (HLA)-specific antibodies, which are associated with longer transplant waiting times and poorer graft outcomes. We hypothesized that additional washing of leucodepleted red cells might reduce antigenic stimulus by removal of residual leukocytes and soluble HLA. A(More)
SUMMARY SARGE is a tool for creating, visualizing and manipulating a putative genetic network from time series microarray data. The tool assigns potential edges through time-lagged correlation, incorporates a clustering mechanism, an interactive visual graph representation and employs simulated annealing for network optimization. AVAILABILITY The(More)
BACKGROUND Because of the presence of confounding antigens, the assignment of HLA antibody specificity is difficult in highly sensitized patients, and the definition of an acceptable HLA mismatch requires a significant workload per patient. We describe a new ELISA method, monoLISA, for detection of immunoglobulin (Ig)G HLA antibody using single recombinant(More)
BACKGROUND More than 40% of patients awaiting a kidney transplant in the UK are sensitised with human leucocyte antigen (HLA) antibodies. Median time to transplantation for such patients is double that of unsensitised patients at about 74 months. Removing antibody to perform an HLA-incompatible (HLAi) living donor transplantation is perceived to be high(More)
Renal transplantation improves quality of life (QoL) and survival in children requiring renal replacement therapy (RRT). Sensitization with development of a broad-spectrum of anti-HLA antibodies as a result of previous transplantation or after receiving blood products is an increasing problem. There are no published reports of desensitization protocols in(More)

BACKGROUND The last Banff 2013 report recognizes acute/active antibody-mediated rejection (ABMR) and C4d staining without evidence of rejection. The goal of our study was to analyze the incidence of C4d deposition after ABO-incompatible transplantation and assess outcomes in patients with ABMR, C4d staining without evidence of rejection (all acute Banff(More)
Intimal vascular lesions are considered features of acute T-cell-mediated rejection yet can occur in the absence of tubulointerstitial inflammation, termed isolated 'v' lesions. The clinical significance of these lesions is unclear. The diagnosis requires a biopsy with the presence of arteries. The frequency of adequate biopsies was analysed in 89 renal(More)
