The link between Helicobacter pylori and iron deficiency (ID) or iron deficiency anemia (IDA) has been investigated recently. We suggested that IDA/ID associated with H. pylori infection might be mediated by inflammation-driven hepcidin production. Patients with complaints of recurrent abdominal pain and dyspepsia aged between 7-16 years were included in this study. Patients were divided into two groups according to H. pylori status in upper gastrointestinal endoscopy. Group I who had H. pylori gastritis (n = 50) received triple antibiotic therapy. Group II (n = 50) who had H. pylori-negative gastritis only received proton pump inhibitor. Thirty healthy children with the similar age and gender were included in the study as a control group. Complete blood count, serum iron levels, iron-binding capacity, ferritin levels, prohepcidin and interleukin-6 (IL-6) values were evaluated in all children at the first visit. Initial tests were repeated after H. pylori eradication. Initial levels of ferritin (p = 0.002), prohepcidin (p = 0.003), and IL-6 (p = 0.004) were found significantly lower in group I compared to group II and the control group. The mean prohepcidin level was lower in the anemic H. pylori-positive group than in non-anemic H. pylori-positive group; however, the difference was not statistically significant. While significant increases in hematocrit and mean corpuscular volume were observed, no significant difference was found in serum ferritin, prohepcidin, or IL-6 level after eradication treatment in H. pylori-positive group. Conclusion: H. pylori-induced gastritis appears to cause an increase in prohepcidin levels and a decrease in ferritin levels, supporting our hypothesis; but this relationship has not been proven.
