Abstract
Objective
To find out prevalence of iron overload in children with leukemia at the end of treatment, and to identify factors affecting iron overload.
Methods
Children (age-1-14 y) treated for Leukemia of our center who completed treatment between January and August 2016 were included in the study. Serum ferritin and iron were measured at completion of treatment and total blood transfusion received throughout treatment was quantified. Serum ferritin >1000 ng/mL was considered as marker of transfusional iron overload.
Results
Out of 66 participants, 55 (83.3%) received red cell transfusions. Average transfused volume was 48 mL/kg, and patients with high-risk leukemia received more transfusions than standard-risk patients. 16 patients (24.2%) demonstrated transfusional iron overload. Total transfused volume and treatment intensity were significant factors associated with iron overload, and total transfused volume of >100 mL/kg (approximately 10 transfusions) was the most important determinant of transfusional iron burden.
Conclusion
One-fourth of pediatric leukemia patients demonstrated iron overload at the end of treatment. These patients need to be monitored and followed-up after treatment to assess need for later chelation therapy.
