Iron deficiency and new insights into therapy

Area of Science:

• Clinical Medicine
• Hematology
• Public Health

Background:

• Iron deficiency and iron deficiency anaemia are significant public health issues in Australia.
• High-risk groups include pre-menopausal women, socially disadvantaged individuals, and Indigenous Australians.
• Diagnosis can be challenging due to inflammation and the need for holistic interpretation of iron studies.

Purpose of the Study:

• To provide an overview of the diagnosis and management of iron deficiency in the Australian context.
• To highlight diagnostic challenges and recommend appropriate investigations.
• To outline current evidence-based treatment strategies for iron replacement.

Main Methods:

• Review of current clinical guidelines and literature on iron deficiency diagnosis and management.
• Emphasis on comprehensive patient history and physical examination.
• Discussion of diagnostic tools including full blood examination, iron studies, and soluble transferrin receptor assays.

Main Results:

• Iron deficiency diagnosis requires careful interpretation of multiple parameters, with soluble transferrin receptor assays useful in complex cases.
• Management involves addressing the underlying cause and implementing effective iron replacement therapy.
• Oral iron (30-100 mg elemental iron daily) is recommended as first-line therapy for most adults.
• Intravenous iron, particularly ferric carboxymaltose, offers a safe and effective alternative for patients unresponsive to oral iron.
• Blood transfusions are reserved for severe, life-threatening anaemia.

Conclusions:

• A systematic approach to diagnosis and management is crucial for addressing prevalent iron deficiency in Australia.
• Personalized treatment strategies, considering oral or intravenous iron, are essential for effective patient outcomes.
• Referral for further investigation, including endoscopy, is indicated for non-responsive cases to rule out underlying pathology like gastrointestinal bleeding.
