Background. Hepcidin is an hepatic peptide that regulates iron homeostasis<br />

by inhibiting iron absorption in enterocytes, <strong>the</strong> efflux <strong>of</strong> iron<br />

from macrophages and <strong>the</strong> release <strong>of</strong> iron from hepatocytes. Its syn<strong>the</strong>sis<br />

is induced by inflammatory stimuli and iron overload, and inhibited<br />

by anemia and hypoxia. It has been suggested that hepcidin may be<br />

responsible for anemia in inflamatory diseases. The aims <strong>of</strong> this study<br />

were to determine <strong>the</strong> hepcidin level in anemia <strong>of</strong> chronic diseases and<br />

iron deficiency anemia in children, and to evaluate its correlations with<br />

inflammatory markers and iron parameters. Methods. The levels <strong>of</strong> serum<br />

hepcidin, high-sensitivity CRP, ferritin, serum iron, transferrin saturation<br />

and soluble transferrin receptor were measured by commercially available<br />

kits, and complete blood count and erythrocyte sedimentation rate<br />

by conventional methods in children with solid tumors (ST, n:16),<br />

inflammatory bowel disease (IBD, n:15), iron deficiency anemia (IDA,<br />

n: 15) and age matched healthy controls (n:15). The study was approved<br />

by our IRB. Results. The mean value <strong>of</strong> serum hepcidin was significantly<br />

higher (p< 0.01) in children with ST (661.5±217.2 ng/dL) (± SD) and<br />

IBD (775.7±395.8 ng/dL) than in age matched healthy controls<br />

(426.1±208.9 ng/dL ) but not significantly different between ST and IBD.<br />

The mean value <strong>of</strong> hepcidin in children with IDA (303.5±81.5 ng/dL)<br />

was not significantly different from that in controls. Serum hepcidin<br />

showed positive correlation with serum ferritin in ST (r:0.77, p:0.01)<br />

and IBD (r: 0.58, p:0.02), and with transferrin saturation in IDA (r:0.59,<br />

p0.05)<br />

respectively. The prevalence <strong>of</strong> Hp infection was 38% in CITP patients<br />

and 46% in <strong>the</strong> control group (p>0.05). The risk factors for acquiring Hp<br />

infection in CITP patients (positive vs negative) were male sex (62% vs<br />

26.5%; p
