The retrospective epidemiological study of Latin Americans with transfusional hemosiderosis is the first regional patient registry to gather data regarding the burden of transfusional hemosiderosis and patterns of care in these patients. Retrospective and cross-sectional data were collected on patients ≥2 years with selected chronic anemias and minimum 20 transfusions. In the 960 patients analyzed, sickle-cell disease (48·3%) and thalassemias (24·0%) were the most frequent underlying diagnoses. The registry enrolled 355 pediatric patients (187 with sickle-cell disease/94 with thalassemia). Serum ferritin was the most frequent method used to detect iron overload. Complications from transfusional hemosiderosis were reported in ∼80% of patients; hepatic (65·3%), endocrine (27·5%), and cardiac (18·2%) being the most frequent. These data indicate that hemoglobinopathies and complications due to transfusional hemosiderosis are a significant clinical problem in the Latin American population with iron overload. Chelation therapy is used insufficiently and has a high rate of discontinuation. |
