Anemia in beta thalassemia

Anemia in beta thalassemia is an inherited hematologic condition characterized by impaired oxygen-carrying capacity due to deficient or absent synthesis of the beta-globin chains of adult hemoglobin Primarily affecting individuals of Mediterranean, Middle Eastern, Central and South Asian, and African ancestry, this quantitative hemoglobinopathy results in an excess of unbound alpha-globin chains that form unstable aggregates within developing and mature erythrocytes Consequently, patients develo...

Anemia in beta thalassemia is an inherited hematologic condition characterized by impaired oxygen-carrying capacity due to deficient or absent synthesis of the beta-globin chains of adult hemoglobin

Primarily affecting individuals of Mediterranean, Middle Eastern, Central and South Asian, and African ancestry, this quantitative hemoglobinopathy results in an excess of unbound alpha-globin chains that form unstable aggregates within developing and mature erythrocytes

These intracellular precipitates drive hallmark pathophysiologic processes, including premature erythroid precursor destruction within the bone marrow—termed ineffective erythropoiesis—and peripheral hemolysis

Consequently, patients develop microcytic, hypochromic anemia ranging clinically from mild, asymptomatic presentations to severe, life-threatening transfusion-dependent disease complicated by extramedullary hematopoiesis, splenomegaly, and systemic iron overload
