Additional role of urine output criterion in defining acute kidney injury.
Diagnosis of acute kidney injury (AKI) has been a major concern due to its association with increased morbidity and mortality. However, the clinical implication of the urine output criterion (UOCr) in diagnosing AKI has not been fully established. ⋯ Although some AKI cases were not identified by the UOCr alone, the UOCr has an additional role in AKI staging, regardless of diuretic use.

Randomized Controlled TrialEffects of atorvastatin on NGAL and cystatin C in chronic kidney disease: a post hoc analysis of the LORD trial.
Neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C are biomarkers of kidney injury and function, respectively. This study assessed whether plasma NGAL and/or serum cystatin C predicted baseline estimated glomerular filtration rate (eGFR) and urinary protein excretion, rate of change of eGFR and urinary protein excretion and whether atorvastatin influenced changes in these biomarkers in patients with chronic kidney disease (CKD). ⋯ NGAL is a biomarker of existing CKD but did not predict CKD progression. Atorvastatin reduced plasma NGAL but the significance and mechanisms require further investigation. Atorvastatin had no significant effect on cystatin C.

Hepatorenal syndrome (HRS) is defined as the occurrence of renal dysfunction in a patient with end-stage liver cirrhosis in the absence of another identifiable cause of renal failure. The prognosis of HRS remains poor, with a median survival without liver transplantation of <6 months. However, understanding the pathogenesis of HRS has led to the introduction of treatments designed to increase renal perfusion and mean arterial blood pressure using vasopressors and albumin, which has led to improvement in renal function in ∼50% of patients.

Comparative StudyExtended daily on-line high-volume haemodiafiltration in septic multiple organ failure: a well-tolerated and feasible procedure.
The outcome of patients with septic multiple organ failure (MOF) remains poor. There are experimental and clinical data indicating a beneficial effect of high-volume haemofiltration. Delivering high-volume therapy is only cost effective using on-line devices because of high costs for additional solution bags in conventional continuous renal replacement therapy (CRRT). We investigated feasibility and effectiveness of extended daily on-line high-volume haemodiafiltration (HDF) with technically maximum convective volume in patients with septic MOF in a pilot study. ⋯ Extended daily on-line HDF using maximum convective volume seems to improve the outcome of septic MOF, especially in the early phase. The investigated mode of treatment proved to be feasible, well tolerated and highly cost effective compared to conventional CRRT. At present, this procedure would be applicable at every ICU facility with nephrological support.
