Hypothyroidism in children with Hb E/β-thalassemia compared between those who received regular transfusion and those who underwent hematopoietic stem cell transplantation.

The studies of hypothyroidism in children with transfusion-dependent hemoglobin E/β-thalassemia (TDT), especially in those who underwent hematopoietic stem cell transplantation (HSCT) are limited. We performed a longitudinal retrospective analysis of thyroid function test (TFT) results among TDT patients aged <25 years who received regular transfusion compared to those who underwent HSCT in Faculty of Medicine Siriraj hospital, Thailand during October 2003 to March 2019. Fifty patients (23 TDT, 27 HSCT) were included.

Differences in longitudinal growth patterns of children and adolescents with transfusion-dependent hemoglobin E/β-thalassemia and those achieving successful hematopoietic stem-cell transplantation.

Background: Short stature is a very common endocrinopathy among children with transfusion-dependent (TD) thalassemia. Hematopoietic stem-cell transplantation (HSCT) is the only effective curative treatment for TD thalassemia. This study aimed to identify and compare the longitudinal growth patterns of children with TD hemoglobin E (Hb E)/β-thalassemia against those of children successfully undergoing HSCT.
