Hyperhemolysis in a patient with beta-thalassemia major
Asian Journal of Transfusion Science
|December 31, 2009
Summary
Hyperhemolysis, a rare complication of blood transfusions in children with beta thalassemia major, was successfully treated with cyclophosphamide. This case highlights cyclophosphamide as a potential therapy for transfusion-induced hyperhemolysis when standard treatments fail.
Area of Science:
- Hematology
- Transfusion Medicine
- Immunology
Background:
- Beta thalassemia major requires lifelong blood transfusions.
- Hyperhemolysis is a rare but serious transfusion complication.
- Diagnosis involves specific laboratory tests like the direct antiglobulin test (DAT).
Observation:
- A 2-year-old boy with beta thalassemia major developed hyperhemolysis post-transfusion.
- The patient exhibited a positive DAT (C3d only) and a weak cold antibody.
- Standard treatments (steroids, immunoglobulin) were ineffective.
Findings:
- Cyclophosphamide therapy was initiated due to treatment resistance.
- Cyclophosphamide demonstrated notable success in managing hyperhemolysis.
- This suggests cyclophosphamide's efficacy in refractory cases.
Implications:
- Cyclophosphamide may be a viable therapeutic option for severe, refractory hyperhemolysis.
- Further research is warranted to confirm cyclophosphamide's role in managing transfusion complications.
- This case expands treatment strategies for beta thalassemia major patients experiencing adverse transfusion reactions.

01:27Disorders 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.

01:15Blood Transfusion
Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.

01:22Lifecycle of Erythrocytes
Erythrocytes, also known as red blood cells, constantly move through blood capillaries. As a result, they damage their plasma membrane due to the continuous friction. Typically, after 100 to 120 days, erythrocytes become rigid and fragile as they wear out. As they pass through small vessels in the spleen and liver, they can get trapped and break apart into fragments.
The resident phagocytic macrophages deal with these damaged cells by engulfing them and separating their globin and heme groups.

02:45Blood Transfusion and Agglutination
Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

01:24Hemoglobin
Hemoglobin is a globular protein made up of four subunits. Two of these subunits are alpha chains, and the other two are beta chains. Each subunit contains a molecule of heme, which has an iron atom and can bind to oxygen. When an oxygen molecule binds to one heme group, it changes the shape of hemoglobin, making it easier for the other heme groups to bind oxygen as well.
When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...

01:14Erythropoiesis
Red blood cells (RBCs) transport oxygen to all body tissues. These cells survive only for 120 days and then need to be replenished. Erythropoiesis is the process of RBC production. In healthy individuals, erythropoiesis ensures all tissues are amply supplied with oxygen. In addition, blood loss due to injury leads to a drop in the physiological oxygen level that will cause erythropoiesis. Any defect in erythropoiesis leads to several physiological disorders, including thalassemia, anemia, and...
