We have demonstrated that caspase-1-deficient (caspase-1(-/-)) mice are functionally and histologically protected against cisplatin-induced acute renal failure (ARF). Caspase-1 exerts proinflammatory effects via the cytokines interleukin (IL)-1beta, IL-18, IL-6, and neutrophil recruitment. We sought to determine the role of the cytokines IL-1beta, IL-18,(More)
Clinical studies demonstrate that acute renal failure (ARF) is associated with increased mortality, which may be due to pulmonary complications. ARF may affect the lung via increased renal production or impaired clearance of mediators of lung injury, such as proinflammatory cytokines. Bilateral nephrectomy is a method to examine directly the deleterious(More)
Patients with acute kidney injury frequently have pulmonary complications. Similarly ischemic acute kidney injury or bilateral nephrectomy in rodents causes lung injury characterized by pulmonary edema, increased pulmonary capillary leak and interstitial leukocyte infiltration. Interleukin-6 is a pro-inflammatory cytokine that is increased in the serum of(More)
BACKGROUND Caspase-1 is a proinflammatory caspase via activation of the cytokine IL-18. We have recently demonstrated that the caspase-1-mediated production of IL-18 plays a deleterious role in ischaemic acute renal failure (ARF) which is independent of neutrophils and CD4+ T cells. The role of caspase-1 in hypoxia-induced membrane injury of proximal(More)
INTRODUCTION Interleukin-6 (IL-6) is a proinflammatory cytokine that increases early in the serum of patients with acute kidney injury (AKI). The aim of this study was to determine whether urine IL-6 is an early biomarker of AKI and determine the source of urine IL-6. Numerous proteins, including cytokines, are filtered by the glomerulus and then(More)
Delayed graft function (DGF) describes dysfunction of the kidney allograft immediately after transplantation and is the most common complication in the immediate posttransplantation period. Although a standardized definition for DGF is lacking, it is most commonly defined as the need for dialysis within the first week after transplant. DGF is caused by a(More)
BACKGROUND Serum cytokines are increased in patients with acute kidney injury (AKI) and predict increased mortality. It is widely assumed that increased renal production of cytokines is the source of increased serum cytokines; the role of extra-renal cytokine production and impaired renal cytokine clearance is less well studied. We hypothesized that(More)
BACKGROUND Descriptions of the sequelae of ABO-incompatible (ABOi) kidney transplantation are limited to single-center reports, which may lack power to detect important effects. METHODS We examined U.S. Renal Data System registry data to study associations of ABOi live-donor kidney transplantation with clinical complications in a national cohort. Among(More)
Currently available immunosuppressive agents can be classified into three categories: induction agents, maintenance therapy, and treatment for rejection. This review article will focus on induction immunosuppression. There are three antibodies which are used for induction therapy: the lymphocyte-depleting agents - anti-thymocyte globulin and alemtuzumab,(More)
PURPOSE OF REVIEW Hepatorenal syndrome (HRS) is an extremely detrimental complication of cirrhosis, with dismal survival in untreated patients. Continued advances in understanding the pathophysiology of HRS have improved HRS recognition and facilitated development of effective treatment strategies. In this article, we review current concepts in HRS(More)
