Background: Iron deficiency anemia is the most common form of anemia worldwide. Recent studies have suggested an association between Helicobacter pylori infection and iron deficiency.
Objective: To investigate the effects of eradicating H. pylori with combination antibiotic therapy on iron deficiency anemia in patients with H. pylori-associated gastritis.
Design: Case series.
Setting: University hospital.
Patients: 30 patients with a long history of iron deficiency anemia in whom H. pylori-associated gastritis was the only pathologic gastrointestinal finding detected.
Intervention: Eradication therapy with two antibiotics and discontinuation of iron replacement therapy.
Measurements: Complete blood count, ferritin levels, and gastroscopy with biopsy to evaluate H. pylori status.
Results: At 6 months, 75% of patients had recovered from anemia (PÂ <Â 0.001), ferritin values increased from 5.7 Â± 0.7 Âµg/L to 24.5 Â± 5.2 Âµg/L (95% CI, 8.85 to 29.97). After 12 months, 91.7% of patients had recovered from anemia.
Conclusions: Cure of H. pylori infection is associated with reversal of iron dependence and recovery from iron deficiency anemia.
