Blood allergy<br /><br />It is an abnormal reaction of the immune system to a certain substance in the blood, which may be blood components or blood products that are transfused to patients in the context of their treatment. Allergy is a rare reaction, but it can be life-threatening to patients if it is not quickly recognized and treated appropriately.<br /><br />Types of blood allergy:<br />1. Blood allergy resulting from blood transfusion:<br />It occurs when the immune system recognizes the components of the transfused blood as foreign bodies, leading to an allergic reaction. Symptoms may include itching, rash, difficulty breathing, or even a serious reaction such as anaphylactic shock.<br /><br />2. Blood allergy due to medications:<br />Allergic reactions may occur as a result of using certain medications that contain components taken from blood, such as some treatments using proteins or antibodies.<br /><br />3. Blood allergy due to vitamin or mineral deficiency:<br />In some cases, deficiencies of certain vitamins and minerals in the blood may lead to unwanted effects on the immune system, making the body sensitive to certain components in the blood.<br /><br />Symptoms:<br />- Skin rash.<br />- Itching.<br />- Swelling of the face or hands.<br />- Difficulty breathing.<br />- Chest pain or low blood pressure.<br /><br />Causes:<br />- Blood type differences: If blood is transfused that is not compatible with the patient's type, an allergic reaction may occur.<br />- Use of medications that contain blood components.<br />- Medical history of patients with previous allergies.<br /><br />For treatment:<br />- Stopping the blood transfusion or the medication that causes the allergy.<br />- Using antihistamines to relieve symptoms.<br />- In severe cases, treatment may require the use of corticosteroids or strong anti-allergy medications.<br />- Continuous monitoring of the patient's health condition after treatment to avoid any complications.<br /><br />Prevention:<br />- Ensure blood type compatibility when transfusing blood.<br />- Conduct tests before blood transfusion to detect the presence of allergies in the patient.<br />- Careful analysis of components that may cause allergic reactions, especially in blood-based medications.<br /><br />Conclusion:<br />Blood allergy is a condition that must be handled with extreme caution, as allergic reactions may vary in severity and may lead to serious complications in some cases.
