A group of renal pathologists, nephrologists, and transplant surgeons met in Banff, Canada on August 2-4, 1991 to develop a schema for international standardization of nomenclature and criteria for the histologic diagnosis of renal allograft rejection. Development continued after the meeting and the schema was validated by the circulation of sets of slides for scoring by participant pathologist...

AIMS Chronic allograft nephropathy is a worldwide issue with the major feature of progressive allograft fibrosis, eventually ending with graft loss. Adenosine has been demonstrated to play an important role in process of fibrosis. Our study aimed to investigate the relationship between adenosine and fibrosis in renal allograft acute rejection in rat. MATERIALS AND METHODS Wistar rats and SD r...

BACKGROUND The term chronic allograft nephropathy (CAN) was deleted in the Eighth Banff Classification and two new categories were introduced: chronic T-cell-mediated rejection (CTMR) and chronic active humoral rejection (CAHR). The aim of this study was to revise our CAN cases diagnosed in the last 4 years, analyse allograft survival rates and identify types of infiltrating cells in the differ...

BACKGROUND We hypothesized that a high within-patient variability in clearance of tacrolimus and mycophenolate mofetil (MMF) would put patients at risk for periods of over- or underimmunosuppression and would thus lead to long-term chronic allograft nephropathy and graft loss after transplantation. METHODS From 297 patients transplanted between 1 January 2000 and 31 December 2004, the within-...

Although short-term outcomes in kidney transplantation have improved dramatically, long-term survival remains a major challenge. A key component of long-term, chronic allograft injury in solid organ transplants is arteriosclerosis characterized by vascular neointimal hyperplasia and inflammation. Establishing a model of this disorder would provide a unique tool not only to identify mechanisms o...

OBJECTIVES Our previous study demonstrated that Ligustrazine reduced renal dysfunction associated with ischemia-reperfusion injury in mice. In this study, we investigated whether Ligustrazine herbal injection had any preventive and therapeutic effectiveness against chronic allograft nephropathy in rats. METHODS Male Lewis rats that received left renal grafts from male Fisher 344 rats were ran...

Chronic rejection or chronic allograft nephropathy (CAN) is the major cause of failure of kidney transplants other than patient death, and has been extensively reviewed (1–5). CAN is characterized by functional impairment with nonspecific pathology: tubular atrophy, interstitial fibrosis, and fibrous intimal thickening (FIT) in the arteries, with variable glomerular lesions. The risk of CAN cor...

Reactive oxygen species (ROS) contribute to the development of interstitial fibrosis and tubular atrophy seen in chronic allograft nephropathy (CAN). As molecular hydrogen gas can act as a scavenger of ROS, we tested the effect of treatment with hydrogen water (HW) in a model of kidney transplantation, in which allografts from Lewis rats were orthotopically transplanted into Brown Norway recipi...
