Intermittent hemodiafiltration as a down-step transition therapy in patients with acute kidney injury admitted to intensive care unit who initially underwent continuous venovenous hemodiafiltration.

Background/aims: Continuous renal replacement therapies (CRRT) are initially employed in patients with acute kidney injury (AKI) in ICU setting. After the period of serious illness, hemodialysis is usually used as a mode of transition from CRRT. Intermittent hemodiafiltration (HDF) is not commonly applied in this scenario.

TNF-α depuration is a predictor of mortality in critically ill patients under continuous veno-venous hemodiafiltration treatment.

Introduction: Critically ill patients with acute kidney injury (AKI) present high mortality rates. The magnitude of inflammatory response could determine the prognosis of such patients. Continuous renal replacement therapy (CRRT) may play an important role in removing inflammatory mediators in patients with AKI.

Serum Soluble-Fas, Inflammation, and Anemia in Acute Kidney Injury.

Anemia is a common feature in critically ill patients. Serum soluble-Fas (sFas) levels are associated with anemia in chronic kidney disease. It is possible that sFas levels are also associated with anemia in acute kidney injury (AKI) patients.

Effects of simvastatin on cytokines secretion from mononuclear cells from critically ill patients with acute kidney injury.

Purpose: To assess the in vitro effects of simvastatin on IL-10 and TNF-α secretion from peripheral blood mononuclear cells (PBMC) of critically ill patients with and without acute kidney injury (AKI).

Methods: PBMC were collected from 63 patients admitted to the intensive care unit (ICU) and from 20 healthy controls. Patients were divided in 3 subgroups: with AKI, with sepsis and without AKI and with AKI and sepsis.

A new spectrophotometric method to detect residual amounts of peroxide after reprocessing hemodialysis filters.

Objective: Reuse of hemodialysis filters is a standard practice and the sterilizing chemical most often employed is peracetic acid. Before starting the dialysis session, filters and lines are checked for residual levels of peracetic acid by means of a non-quantitative colorimetric test that is visually interpreted. The objective of this study was to investigate a new quantitative spectrophotometric test for detection of peracetic acid residues.

The use of regional citrate anticoagulation for continuous venovenous hemodiafiltration in acute kidney injury.

Objective: Continuous renal replacement therapy is commonly used in the treatment of acute kidney injury. Although the optimal anticoagulation system is not well defined, citrate has emerged as the most promising method. We evaluated the data of 143 patients with acute kidney injury subjected to citrate-based continuous venovenous hemodiafiltration.
