Erythroid bone marrow activity and red cell hemoglobinization in iron sufficient beta-thalassemia heterozygotes as reflected by soluble transferrin receptor and reticulocyte hemoglobin in content. Correlation with genotypes and Hb A(2) levels.

Abstract excerpt

BACKGROUND AND OBJECTIVES: Ferrokinetic studies and erythroid cell ultrastructural studies have indicated some degree of ineffective erythropoiesis in heterozygous beta-thalassemia, although a wide case-to-case variation was observed. In this study we applied rapid biochemical and hematologic measurements to assess erythroid marrow activity (sTfR) and reticulocyte hemoglobin content (CHr) in iron-sufficient...
