Module 1: Physiology of iron metabolism

Iron deficiency (ID) is one of the most common nutritional deficiencies in the world and a major cause of anaemia.((1) In addition, ID alone or with anaemia – a condition known as iron deficiency anaemia (IDA) – is prevalent in patients with chronic kidney disease (CKD).(2,3) Despite its frequency, ID/IDA is often neglected as a condition per se in CKD, which can lead to worsening outcomes for patients.(4) Understanding the key principles of iron metabolism is fundamental to appreciating the advantages and limitations of the diagnostic tests and treatment options available in the management of ID/IDA in CKD.

The ‘Module 1: Physiology of iron metabolism’ was developed with scientific input and guidance from Professor Angel de Francisco (Head of the Dialysis Unit and Nephrology Section at the Hospital Universitario Valdecilla, Santander, Spain). The module is available in a user-friendly interactive presentation format that is divided over four chapters to enable you to learn at your own pace and gain maximum benefit from the information presented.

Chapters 1 and 2 provide you with a comprehensive overview of iron physiology, including the different types of iron available, the various dietary sources of iron, how iron is distributed throughout the body and the many functions involving iron within the body, beyond red blood cell production. Chapters 3 and 4 explore how iron homeostasis is maintained in the body and the principal proteins involved in iron transport and storage in the body, especially ferritin and transferrin.

Interactive question-and-answer sections at the end of each chapter will evaluate your learning and improve your understanding of the physiology of iron metabolism.
