Role of intensive glucose control in development of renal end points in type 2 diabetes mellitus: systematic review and meta-analysis intensive glucose control in type 2 diabetes.

Background: Aggressive glycemic control has been hypothesized to prevent renal disease in patients with type 2 diabetes mellitus. A systematic review was conducted to summarize the benefits of intensive vs conventional glucose control on kidney-related outcomes for adults with type 2 diabetes.

Methods: Three databases were systematically searched (January 1, 1950, to December 31, 2010) with no language restrictions to identify randomized trials that compared surrogate renal end points (microalbuminuria and macroalbuminuria) and clinical renal end points (doubling of the serum creatinine level, end-stage renal disease [ESRD], and death from renal disease) in patients with type 2 diabetes receiving intensive glucose control vs those receiving conventional glucose control.

Preoperative serum brain natriuretic peptide and risk of acute kidney injury after cardiac surgery.

Background: Acute kidney injury (AKI) after cardiac surgery is associated with poor outcomes and is difficult to predict. We conducted a prospective study to evaluate whether preoperative brain natriuretic peptide (BNP) levels predict postoperative AKI among patients undergoing cardiac surgery.

Methods And Results: The Translational Research Investigating Biomarker Endpoints in Acute Kidney Injury (TRIBE-AKI) study enrolled 1139 adults undergoing cardiac surgery at 6 hospitals from 2007 to 2009 who were selected for high AKI risk.

Postoperative biomarkers predict acute kidney injury and poor outcomes after pediatric cardiac surgery.

Acute kidney injury (AKI) occurs commonly after pediatric cardiac surgery and associates with poor outcomes. Biomarkers may help the prediction or early identification of AKI, potentially increasing opportunities for therapeutic interventions. Here, we conducted a prospective, multicenter cohort study involving 311 children undergoing surgery for congenital cardiac lesions to evaluate whether early postoperative measures of urine IL-18, urine neutrophil gelatinase-associated lipocalin (NGAL), or plasma NGAL could identify which patients would develop AKI and other adverse outcomes.

Marked variation in the definition and diagnosis of delayed graft function: a systematic review.

Background: The term delayed graft function (DGF) is commonly used to describe the need for dialysis after receiving a kidney transplant. DGF increases morbidity after transplantation, prolongs hospitalization and may lead to premature graft failure. Various definitions of DGF are used in the literature without a uniformly accepted technique to identify DGF.

Renal impairment predicts long-term mortality risk after acute myocardial infarction.

Renal function predicts mortality after acute myocardial infarction (AMI), but it is unknown whether the prognostic importance of renal function persists over time. This study examined how the association between renal function and mortality changed in the 10 yr after AMI in a cohort of patients. In 118,753 patients (age >/=65 yr) from the Cooperative Cardiovascular Project, mean Cockcroft-Gault creatinine clearance was 55 +/- 24 ml/min and estimated GFR was 57 +/- 21 ml/min per 1.

Acute renal failure in hematopoietic cell transplantation.

Hematopoietic cell transplantation is a common procedure for the treatment of malignancies and some non-malignant hematologic disorders. In addition to other transplant-related organ toxicities, acute renal failure is a common complication following transplantation. This review discusses the incidence, timing, etiologies, risk factors, and prognosis of renal failure associated with three commonly used transplantation procedures - myeloablative autologous, myeloablative allogeneic, and non-myeloablative allogeneic transplantation.
