ABSTRACT
Acute kidney injury is a clinical syndrome which is generally defined as an abrupt decline in glomerular filtration rate causing accumulation of nitrogenous products and rapid development of fluid, electrolyte and acid-base disorders. It is an important clinical problem increasing mortality in patient with several co-morbid conditions. The frequency of acute kidney injury occurrence varies from 5% on the inpatients wards to 30-50% in patients from intensive care units. Serial measurement of creatinine and urine volume do not make it possible to diagnose acute kidney injury at early stages. Serum creatinine may be influenced by age, weight, hydration status and become apparent only when the kidneys have lost 50% of their function. For that reasons we need new markers. Here, we are reviewing the most promising new acute kidney injury markers, neutrophil gelatinase associated lipocalin, cystatin-C, kidney injury molecule-1, liver fatty acid binding proteins and IL-18.
