D56.2

Clinical Causes: Genetic mutations inherited from parents Autosomal recessive inheritance pattern, meaning a person needs to inherit the defective gene from both parents to be affected Mutations affecting the HBD and HBB genes, which code for delta and beta globin chains respectively

Key Symptoms: Mild to moderate anemia, leading to fatigue and weakness Pale skin and mucous membranes Shortness of breath or rapid breathing Paleness of the eyelids or conjunctiva Rapid heartbeat Delayed growth and development in children Splenomegaly (enlarged spleen) in some cases

Diagnosis Path: Diagnosing delta-beta thalassemia involves a combination of blood tests and genetic studies. Key diagnostic procedures include: - Complete blood count (CBC): shows anemia with microcytic (small cell) and hypochromic (pale) red blood cells. - Hemoglobin electrophoresis: identifies abnormal hemoglobin types and levels. - Genetic testing: confirms mutations in the HBD and HBB genes. - Bone marrow examination in some cases to assess blood cell production. The diagnosis helps differentiate delta-beta thalassemia from other forms of thalassemia and blood disorders.

Treatment Protocols: Management of delta-beta thalassemia focuses on relieving symptoms and preventing complications. Treatment options include: - Regular monitoring of hemoglobin levels and overall health. - Blood transfusions in cases of severe anemia. - Iron chelation therapy if frequent transfusions lead to iron overload. - Folic acid supplements to support red blood cell production. - Splenectomy (removal of the spleen) in some cases to reduce hemolysis. - Genetic counseling for affected individuals and carriers to understand inheritance patterns. While there is no cure, appropriate management can improve quality of life and alleviate symptoms.
