Abstract
En 中文
alpha-Thalassemia is an inherited blood disorder characterized by decreased synthesis of alpha-globin chains that results in an imbalance of alpha and beta globin and thus varying degrees of ineffective erythropoiesis, decreased red blood cell (RBC) survival, chronic hemolytic anemia, and subsequent comorbidities. Clinical presentation varies depending on the genotype, ranging from a silent or mild carrier state to severe, transfusion-dependent or lethal disease. Management of patients with alpha-thalassemia is primarily supportive, addressing either symptoms (eg, RBC transfusions for anemia), complications of the disease, or its transfusion-dependence (eg, chelation therapy for iron overload). Several novel therapies are also in development, including curative gene manipulation techniques and disease modifying agents that target ineffective erythropoiesis and chronic hemolytic anemia. This review of alpha-thalassemia and its various manifestations provides practical information for clinicians who practice beyond those regions where it is found with high frequency.
