Neutrophil gelatinase-associated lipocalin (NGAL) is produced in response to tubular injury. Contrast-induced acute kidney injury (CI-AKI) is associated with adverse outcomes in chronic kidney disease (CKD) patients. We sought to characterize blood NGAL level and the degree of kidney injury in CKD patients who underwent coronary angiography. ⋯ Baseline and post-procedure NGAL are progressively elevated according to the baseline stage of CKD. Using a twofold rise in NGAL, 46.7% of composite CI-AKI is detected and complements the 53.3% of cases identified using KDIGO criteria. Traditional risk predictors were not independently associated with this composite outcome.

The imbalance between organ demand and supply causes the increasing use of suboptimal donors. The aim of this study is to investigate the survival and allograft function of kidney transplantation from standard (SLD) and elderly living (ELD), standard criteria (SCDD) and expanded criteria deceased (ECDD) donors. All patients transplanted from 1997 to 2005 were investigated according to the donor characteristics. ⋯ In multivariate analysis, ELD, experience of an acute rejection episode and presence of delayed graft function were the independent predictors for death censored graft loss. Transplantation of a suboptimal kidney provides inferior graft survival and function. A higher number of deaths due to infection in the early post-transplant period in the ECDD group are noteworthy.

Neutrophil-lymphocyte ratio (NLR) is an easily calculated, sensitive, and accurate marker for prognosis and diagnosing sepsis, cardiovascular disease and cancer. As sepsis and septic shock are main causes of acute kidney injury (AKI) intensive care unit (ICU), we investigated whether NLR is an early predictor of AKI in patients with severe sepsis. We compared NLR's predictive power with that of other inflammation-related variables. ⋯ NLR is superior to CRP, and WBC for predicting the development of AKI in patients with severe sepsis.
