2013 Mar - Medication Dosing in Critically Ill Patients With Acute Kidney Injury Treated With Renal Replacement Therapy
Scoville BA, Mueller BA.; Am J Kidney Dis. 2013 Mar;61(3):490-500.
Critically ill patients with acute kidney injury may be treated with a variety of renal replacement therapies (RRTs). Each of these RRTs has profound yet differing effects on drug dosing...

Iodinated contrast media (CM) are used in many investigations that a patient may undergo during the course of an in-patient stay. For the vast majority of patients, exposure to CM has no sequelae; however, in a small percentage, it can result in a worsening in renal function termed contrast-induced acute kidney injury (CI-AKI)..

The clinical integration of novel biomarkers specific for kidney damage have brought the promise of a new era in our understanding of and care for those patients susceptible to or suffering from acute kidney injury (AKI) and has consistently been viewed as a top research priority...
2013 Jan - Nephrologist follow-up improves all-cause mortality of severe acute kidney injury survivors
Harel Z, Wald R, Bargman JM, Mamdani M, Etchells E, Garg AX, Ray JG, Luo J, Li P, Quinn RR, Forster A, Perl J, Bell CM.; Kidney Int. 2013 Jan 16. doi: 10.1038/ki.2012.451. [Epub ahead of print]
Survivors of severe acute kidney injury remain at high risk of death well after apparent recovery from the initial insult. Here we determine whether early nephrology follow-up after a hospitalization complicated by severe acute kidney injury associates with patient survival.
2013 Jan - High Cut-Off Renal Replacement Therapy for Removal of Myoglobin in Severe Rhabdomyolysis and Acute Kidney Injury: A Case Series
Heyne N, Guthoff M, Krieger J, Haap M, Häring HU.; Nephron Clin Pract. 2013 Jan 16;121(3-4):c159-c164. [Epub ahead of print]
Background/Aim: Rhabdomyolysis is associated with the release of myoglobin into the circulation, promoting acute kidney injury (AKI). In severe rhabdomyolysis, dialysis-dependent AKI doubles mortality. Standard blood purification techniques have limited efficacy in removing myoglobin. We describe high cut-off (HCO) renal replacement therapy (RRT) as a novel approach for extracorporeal elimination of myoglobin in rhabdomyolysis-associated AKI.

Background: Extracorporeal membrane oxygenation (ECMO) is increasingly used in the intensive care unit (ICU) setting to improve gas exchange in patients with acute respiratory distress syndrome as well as in patients pre- and post-heart and lung transplantation. In this clinical setting, acute kidney injury (AKI) is frequently observed. So far, it is unknown how AKI affects the survival of critically ill patients receiving ECMO support and whether veno-veno and veno-arterial ECMO have different effects on kidney function.

Tumor lysis syndrome (TLS) describes the clinical and laboratory sequelae that result from the rapid release of intracellular contents of dying cancer cells. It is characterized by the release of potassium, phosphorous, and nucleic acids from cancer cells into the blood stream, with the potential to cause hyperkalemia; hyperphosphatemia and secondary hypocalcemia; hyperuricemia; AKI; and, should usual homeostatic mechanisms fail, death.

AKI is common in patients with cancer, and it causes interruptions in therapy and increased hospital length of stay, cost, and mortality. Although cancer patients are susceptible to all of the usual causes of AKI in patients without cancer, there are a number of AKI syndromes that occur more frequently or are unique to this patient population....

BACKGROUND AND OBJECTIVES: Peritoneal dialysis is still used for AKI in developing countries despite concerns about its limitations. The objective of this study was to explore the role of high-volume peritoneal dialysis in AKI patients in relation to metabolic and fluid control, outcome, and risk factors associated with death.

The use of alternative medicine is highly prevalent around the world; in many areas, this is so because of lack of access to, or trust in, Western medicine, and also because they are considered "natural" and therefore safe. The kidney is an organ vulnerable to toxic insults by virtue of its anatomy and function. Reports of nephrotoxicity associated with alternative medicine use encompass all forms of renal dysfunction, ranging from electrolyte abnormalities and proteinuria to acute and CKD, renal failure, and death....

Critically ill patients often have deranged hemodynamics. Physical examination, central venous pressure, and pulmonary artery occlusion pressure ("wedge") have been shown to be unreliable at assessing volume status, volume responsiveness, and adequacy of cardiac output in critically ill patients. Thus, invasive and noninvasive cardiac output monitoring is a core feature of evaluating and managing a hemodynamically unstable patient...

"Bath salts" are becoming recognized as a frequently abused and highly addictive substance that can be obtained legally in some areas. These agents contain stimulant compounds, such as methylenedioxopyrrovalerone and mephedrone, that have been associated with sympathomimetic effects and psychotic features, such as paranoia, delusions, agitation, and confusion. They may have a benign course; however, intoxication with these agents may lead to severe cardiovascular and neurologic complications and death.

BACKGROUND: Hyponatremia is the most common electrolyte abnormality in clinical practice, yet little is known about its frequency in patients with cancer or its impact on their clinical outcomes.
2011 Dec - Blood and ultrafiltrate dosage of citrate as a useful and routine tool during continuous venovenous haemodiafiltration in septic shock patients

BACKGROUND: Citrate anticoagulation is gaining popularity in renal replacement therapies (RRT) for critically ill patients. In order to study whether citrate accumulates in septic shock patients, we determined citrate in plasma and dialysate during continuous venovenous haemodiafiltration (CVVHDF).

BACKGROUND: Acute kidney injury (AKI) in hospitalized human immunodeficiency virus (HIV)-infected patients in the highly active antiretroviral therapy (HAART) era has not been extensively addressed. The aim of the present study was to analyze the incidence, etiology, risk factors and the impact of AKI on in-hospital mortality in this population.
2011 Dec - Performance of the third-generation models of severity scoring systems (APACHE IV, SAPS 3 and MPM-III) in acute kidney injury critically ill patients
Costa E Silva VT, de Castro I, Liaño F, Muriel A, Rodríguez-Palomares JR, Yu L.; Nephrol Dial Transplant. 2011 Dec;26(12):3894-901. Epub 2011 Apr 19.
BACKGROUND: Severity scores are useful to guarantee similar disease severity among groups in clinical trials and to enable comparison between different studies. The aim of this study was to assess the performance of the third generation models of severity scoring systems [simplified acute physiology score (SAPS) 3, acute physiology and chronic health evaluation (APACHE) IV and mortality probability model (MPM)-III] in acute kidney injury (AKI) patients in the intensive care unit (ICU).

N-benzylpiperazine (BZP) is the active ingredient in recreational 'party' pills with a stimulant, euphoric mechanism of action akin to that of 3,4, methylenedeoxymethamphetamine (MDMA or ecstasy). Many people (ab)use BZP-based party pills usually without any significant toxic effects. However, nephrotoxicity secondary to hyperthermia and rhabdomyolysis has been reported. Another serious renal related side effect is hyponatraemia with acute cerebral oedema.
2011 Sep - Severe acute kidney injury not treated with renal replacement therapy: characteristics and outcome
Schneider AG, Uchino S, Bellomo R.; Nephrol Dial Transplant. 2011 Sep 8. [Epub ahead of print]
BACKGROUND: Only a proportion of critically ill patients with severe [RIFLE (Risk, Injury, Failure, Loss, End-stage renal disease) criteria, class-F] acute kidney injury (AKI) appear to receive renal replacement therapy (RRT). The aim of this study was to study the characteristics and outcome of patients with severe (RIFLE-F) AKI who did not receive RRT.
