Monitoring 25-OH and 1,25-OH vitamin D levels in hemodialysis patients after starting therapy: Does it make sense?

Background And Aims: In hemodialysis patients, monitoring 25-hydroxyvitamin D (25(OH)D) levels is recommended. It is however unclear if monitoring 1,25-dihydroxyvitamin D (1,25(OH)D) levels is interesting.

Materials And Methods: We repeatedly measured 1,25(OH)D (DiaSorin Liaison analyser) and 25(OH)D (LCMS/MS) concentrations in patients newly treated by active or native vitamin D to study the impact of such treatments on serum concentrations.

NGAL Usefulness in the Intensive Care Unit Three Hours after Cardiac Surgery.

Objective. Neutrophil gelatinase-associated lipocalin (NGAL) measured by a research ELISA is described as an early marker of acute kidney injury (AKI). The aim of this study is to define the usefulness of plasma NGAL (pNGAL) and urine NGAL (uNGAL) measured with platform analysers to detect AKI 3 hours after cardiac surgery in fifty adult patients.

[Acute kidney injury: from concept to practice].

Definition and classification of acute renal failure evolved in recent years. The acronym "Acute Kidney Injury" replaces "Acute Renal Failure". The RIFLE classification spreads the AKI in three degrees of severity, and two degrees of disease duration.
