Antibody-mediated rejection (AbAR) is increasingly recognized in the renal allograft population, and successful therapeutic regimens have been developed to prevent and treat AbAR, enabling excellent outcomes even in patients highly sensitized to the donor prior to transplant. It has become critical to develop standardized criteria for the pathological(More)
BACKGROUND Abdominal aortic aneurysm (AAA) expansion is characterized by extracellular matrix degradation and widespread inflammation. In contrast, the processes that characterize AAA rupture are not well understood. The aim of this study was to investigate the proteolytic and cellular activity of ruptured AAA, focusing on matrix metalloproteinases (MMPs)(More)
AIM To investigate vascular endothelial growth factor (VEGF) mRNA expression in glomerular disease in the context of heavy proteinuria. METHODS Non-radioisotopic in situ hybridisation was performed using a cocktail of 12 deoxyoligonucleotides complementary to VEGF mRNA labelled during solid phase synthesis with 2,4-dinitrophenyl. Archival renal biopsies(More)
We sought to assess the interobserver variation of the new International Society of Nephrology/Renal Pathology Society (ISN/RPS) classification of lupus nephritis when compared with the previous World Health Organization classification, when used by pathologists throughout the UK. We also sought differences in how the 2 classifications were applied to a(More)
The use of reverse transcription (RT) PCR for relative quantitation of gene transcripts relies on the reproducibility of the individual RT, PCR and product measurement steps. Semi-competitive RT-PCR (RT-cPCR) uses an internal competitor template in the PCR step to improve quantitation. We have surveyed the reproducibility of RT, PCR, RT-cPCR and(More)
BACKGROUND The aim of this study was to compare the effect of Neoral cyclosporin- and tacrolimus-based therapy on the development of renal allograft fibrosis (chronic allograft nephropathy; CAN) in a prospective randomized trial. METHODS A total of 102 patients undergoing renal transplantation were randomized to immunosuppression with either microemulsion(More)
BACKGROUND Nephrin recently has been identified as a putative adhesion molecule, expressed in the glomerulus, in which mutations cause congenital nephrotic syndrome of Finnish type. We sought to determine whether expression of nephrin is altered in human glomeruli in patients with acquired nephrotic syndrome. METHODS We performed PCR amplification of(More)
BACKGROUND Renal warm ischaemia-reperfusion injury is pertinent to vascular and transplant surgery. While established models provide functional and morphological data the authors wanted to be able to correlate this with the underlying pathophysiology at any chosen time point, thus allowing future interventional effects on reperfusion injury to be evaluated.(More)
BACKGROUND Clinical trials in renal transplantation must use surrogate markers of long-term graft survival if conclusions are to be drawn at acceptable speed and cost. Morphologic changes in transplant biopsies provide the earliest available evidence of damage, and "protocol" biopsies from stable grafts can be used to reduce the number of patients needed in(More)
BACKGROUND Proteinuria and tubular atrophy have both been closely linked with progressive renal failure. We hypothesized that apoptosis may be induced by tubular cell exposure to heavy proteinuria, potentially leading to tubular atrophy. Apoptosis was studied in a rat model of "pure" proteinuria, which does not induce renal impairment, namely(More)
