Abstract

Background and aims: Helicobacter pylori (H. pylori) is recognized as a causative agent for unexplained iron-deficiency anemia (IDA). We evaluated many background factors influencing an iron-deficiency state in adult patients with various H. pylori-infected upper gastrointestinal tract diseases.

Method: Study 1: H. pylori-infected 121 patients (nodular gastritis (NG) (n = 19), duodenal ulcer (DU) (n = 30), or gastric ulcer (GU) (n = 47), or gastric hyperplastic polyp (GHP) (n = 25)) were enrolled. The RBC count and hemoglobin, iron, ferritin, pepsinogen (PG) I, PG II, gastrin, and anti-H. pylori antibody (Ab) levels in the serum were measured. Study 2: H. pylori-infected 105 patients (NG, n = 19; DU, n = 43; GU, n = 32; GHP, n = 11) and non-H. pylori-infected individuals (n = 35) were examined for the levels of prohepcidin, ferritin, and iron in the serum. In addition, we measured the data before and after the H. pylori eradication.

Results: In the patients with GHP and NG, hypoferritinemia was observed in comparison with the GU and DU patients. In the GHP patients, low levels of PG I, a decreased PG I/II ratio, and hypergastrinemia were observed. The levels of serum prohepcidin in the patients with H. pylori-associated disease were higher than those in the uninfected adults. In the patients with NG, the serum prohepcidin levels were higher than those in the other H. pylori-infected patient groups and decreased after the eradication.

Conclusion: H. pylori-related iron-deficiency state might be associated with several factors, such as hypochlorhydria and hepcidin, in patients with GHP or NG.
