Iron Overload: Pathophysiology, Diagnosis and Monitoring

Area of Science:

• Hematology
• Internal Medicine
• Medical Diagnostics

Background:

• Iron overload is a serious condition linked to genetic disorders (hereditary hemochromatosis) or secondary causes like ineffective erythropoiesis and blood transfusions.
• It leads to progressive tissue iron accumulation, causing significant health risks including organ damage and increased cancer risk.

Purpose of the Study:

• To provide a comprehensive overview of iron overload pathophysiology.
• To detail current diagnostic and monitoring techniques for iron overload.
• To enhance clinical awareness and management strategies for iron overload.

Main Methods:

• Review of existing literature on iron overload pathophysiology.
• Analysis of diagnostic methods including laboratory tests (serum ferritin, transferrin saturation) and imaging (MRI).
• Evaluation of monitoring strategies focusing on iron indices and organ damage markers.

Main Results:

• Diagnosis relies on clinical suspicion, elevated iron indices, and imaging, prompting genetic testing for hereditary causes.
• Chronic iron overload can lead to myocardial dysfunction, liver cirrhosis, and hepatocellular carcinoma.
• Effective monitoring involves tracking iron levels and organ damage markers over time.

Conclusions:

• Understanding iron overload pathophysiology is key to developing accurate diagnostic and monitoring tools.
• Early diagnosis and consistent monitoring are essential for managing iron overload and preventing severe clinical outcomes.
• This review aims to update knowledge and improve clinical management of iron overload.
