The researchers found iron infusions reduced the risk of hospitalisation due to heart failure and dying from a heart related cause by 18% compared to usual care.
Generally, in the UK oral preparations are trialled before using parenteral delivery, [20] unless there is the requirement for a rapid response, previous intolerance to oral iron or likely failure to respond. Intravenous iron may decrease the need for blood transfusions however it increases the risk of infections when compared to oral iron. [21]
IV iron infusions are administered to patients who cannot use oral supplementation to treat their deficiency, or if oral treatment has proven ineffective. [8] Oral iron supplementations are the first line of care for iron deficiency and iron deficiency anaemia. Anaemic patients are treated with iron tablets containing 100 mg to 200 mg of iron. [7]
Iron-deficiency anemia is anemia caused by a lack of iron. [3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [1]
Iron catalyzes the mitochondrial inner membrane, resulting in peroxidative damage and upset of oxidative phosphorylation. ATP synthesis is hampered, leading to cellular dysfunction, and even death. Hypotension develops again 2 to 5 days after iron ingestion, in association with severe organ dysfunction involving mainly the liver, heart, and brain.
Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress, as elevated intracellular iron levels increase free radical formation via the Fenton reaction.
