Serum neutrophil gelatinase-associated lipocalin for predicting anemia of inflammation in children with urinary tract infection.

Anemia of inflammation (IA), the second most common cause of childhood anemia, results from macrophage iron sequestration and impaired erythropoiesis. Neutrophil gelatinase-associated lipocalin (NGAL) plays an important role in innate microbial immunity through its influence on intracellular iron homeostasis and inhibition of erythropoiesis. The predictive value of NGAL in IA was assessed in 74 children (age 6.
