[Iron deficiency and iron deficiency anemia]
1Hokkaido Blood Center.
Summary
Iron deficiency anemia (IDA) is common, often caused by blood loss. New oral and intravenous iron preparations are improving treatment outcomes for IDA and iron deficiency symptoms.
Area of Science:
- Hematology
- Internal Medicine
- Pharmacology
Background:
- Iron metabolism is a semi-closed system with limited excretion and absorption.
- Persistent bleeding, particularly gastrointestinal or gynecological, depletes iron stores.
- Iron deficiency anemia (IDA) is the most common anemia, affecting ~70% of cases, and iron deficiency can cause symptoms even without anemia.
Purpose of the Study:
- To review the current understanding of iron metabolism and iron deficiency anemia.
- To highlight the underutilization of iron-related diagnostic tests.
- To discuss new oral and intravenous iron preparations and their role in IDA treatment.
Main Methods:
- Literature review of iron metabolism, IDA, and iron preparations.
- Analysis of clinical trial data, particularly from Japan.
- Examination of diagnostic and therapeutic trends in iron deficiency management.
Main Results:
- Iron deficiency can manifest with symptoms beyond anemia.
- Iron-related diagnostic tests are underutilized.
- New oral (ferric citrate hydrate) and intravenous (ferric carboxymaltose, ferric derisomaltose) iron preparations offer expanded treatment options.
Conclusions:
- Iron deficiency anemia remains a significant clinical challenge.
- Optimal utilization of diagnostic tests and new iron preparations can improve patient outcomes.
- Ongoing research and clinical trials are crucial for advancing IDA management.

Disorders of Erythrocytes
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Microbes and Other Elemental Cycles
Microbial activity plays a pivotal role in the biogeochemical cycling of iron and manganese, especially at the redox gradients characteristic of stratified aquatic environments. These cycles are driven by microbial transformations between oxidized and reduced forms of the metals, allowing organisms to exploit them for metabolic energy and structural purposes.Iron Cycling Across Redox GradientsIn neutral, oxygen-rich surface waters, iron is predominantly found in its oxidized, insoluble ferric...
Necrosis
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

Minerals
Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.
Factors Affecting Erythropoiesis
The cardiovascular system regulates the number of erythrocytes in the bloodstream to ensure optimal oxygen transport. It also prevents over-proliferation of these cells, which helps to maintain blood viscosity and flow rate.
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
EPO then...

Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
