[Unexplained iron-deficiency due to Helicobacter pylori]

Area of Science:

• Gastroenterology
• Hematology
• Infectious Diseases

Background:

• Iron-deficiency is a widespread nutritional deficiency globally.
• Chronic blood loss is a common cause in Western countries, but the source remains unidentified in up to 30% of patients.
• Routine investigations often fail to reveal the underlying cause of iron deficiency.

Observation:

• This study details three cases (two males, one female) presenting with fatigue and iron deficiency.
• Endoscopic examinations in these patients showed no abnormalities.
• Helicobacter pylori infection was identified as a potential primary cause for their iron deficiency.

Findings:

• Successful eradication of H. pylori led to sustained normalization of iron status and hemoglobin levels in all patients.
• The underlying mechanism linking H. pylori to iron deficiency requires further investigation.
• Eradication therapy resulted in significant clinical improvement in iron balance and status for these individuals.

Implications:

• Investigating H. pylori infection is recommended for patients with unexplained iron deficiency.
• H. pylori eradication may be a crucial therapeutic strategy for resolving iron deficiency in affected individuals.
• This highlights a potential link between a common bacterial infection and a prevalent nutritional disorder, impacting patient management strategies.
