  • Title: [Iron deficiency anemia and H. pylori].
    Author: Shimada T, Hiraishi H.
    Journal: Nihon Rinsho; 2008 Mar; 66(3):584-9. PubMed ID: 18326330.
    Abstract:
    Although Helicobacter pylori (H. pylori) is a causative agent for chronic gastritis, peptic ulcer, and gastric carcinoma, this pathogen is also responsible for some extra-gastric diseases. Both epidemiologic and clinical studies suggest that H. pylori infection is a risk factor for iron deficiency anemia (IDA). Several case reports and case series showed reversal of IDA after eradication of H. pylori. Although the mechanisms for H. pylori-associated IDA is not fully understood, H. pylori-induced chronic pangastritis with resultant achlorhydria and reduced ascorbic acid secretion in the gastric mucosa may lead to reduced iron absorption. Uptake of iron by H. pylori is also suggested. Further properly designed trials are needed to confirm a causal relationship between H. pylori and IDA.
