beta-thalassemia intermedia
A moderate form of beta-thalassemia with anemia that is less severe than thalassemia major but more significant than thalassemia minor.
Full Definition
Beta-thalassemia intermedia represents a clinical phenotype of beta-thalassemia that falls between the mild thalassemia minor (trait) and the severe thalassemia major. Patients typically present with moderate anemia, may require occasional blood transfusions during periods of stress or illness, but do not depend on regular transfusions for survival. The condition can lead to complications including bone deformities, extramedullary hematopoiesis, and iron overload from increased intestinal absorption. Editorial teams should distinguish this clearly from other thalassemia variants in patient education materials and clinical documentation.
Usage
Usage note: Specify 'beta-thalassemia' to distinguish from alpha-thalassemia variants.
