Clinical Complications and Their Management

The hallmarks of thalassemias are ineffective erythropoiesis and peripheral hemolysis leading to a cascade of events responsible for several clinical complications. This pathophysiologic mechanism can be partially controlled by blood transfusions or by correction of the severity of ineffective erythropoiesis. Thalassemias include a spectrum of phenotypes. Two main groups can be clinically distinguished: transfusion-dependent (TDT) and non–transfusion-dependent (NTDT) thalassemia. Both conditions are characterized by several clinical complications along life; some are shared, whereas some have higher prevalence in one group over the other. The authors present the most common clinical complications in TDT and NTDT and their management.
