Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen ...
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]
Injection site reactions (ISRs) are reactions that occur at the site of injection of a drug. They may be mild or severe and may or may not require medical intervention. Some reactions may appear immediately after injection, and some may be delayed. [1] Such reactions can occur with subcutaneous, intramuscular, or intravenous administration.
Main symptoms that may appear in anemia [20] The hand of a person with severe anemia (on the left, with ring) compared to one without (on the right). A person with anemia may not have any symptoms, depending on the underlying cause, and no symptoms may be noticed, as the anemia is initially mild, and then the symptoms become worse as the anemia worsens.
An acute hemolytic transfusion reaction (AHTR), also called immediate hemolytic transfusion reaction, is a life-threatening reaction to receiving a blood transfusion. AHTRs occur within 24 hours of the transfusion and can be triggered by a few milliliters of blood. The reaction is triggered by host antibodies destroying donor red blood cells.
Heart disease, liver damage, and kidney failure can result from iron buildup in these organs. [5] Symptoms of sideroblastic anemia usually resemble the common symptoms of anemia. In addition to the symptoms listed above, patients with sideroblastic anemia may experience shortness of breath, heart palpitations, and headache.
Any form of intravenous infusion carries the risk of infection. Risk is heightened when the equipment being used is not properly sterilised. In intravenous iron infusions, free iron has been shown to potentiate bacterial growth. [12] Evidence associated with intravenous iron therapy and infection is inconclusive.
[5] [6] When occurring as a result of a medication, it is also known as an infusion reaction. [1] The term cytokine storm is often used interchangeably with CRS but, despite the fact that they have similar clinical phenotype, their characteristics are different. When occurring as a result of a therapy, CRS symptoms may be delayed until days or ...
