- Abstract
Background: Beta thalassemia major (BTM) and its treatment by hematopoietic stem cell transplantation (HSCT) may have deleterious effects on the endocrine systems. We assessed endocrine complications of HSCT in pediatric patients for 3 months., Methods: In 20 (6 female) pediatric major thalassemic patients (mean age of 10.8 ± 3.9 years old), prolactin, luteinizing hormone (LH), follicle-stimulating hormone (FSH), T4, T3, thyroid-stimulating hormone (TSH), IGF-1, testosterone (in males) or estradiol (in females) were measured as a batch at the Endocrinology and Metabolism Research Center (EMRC) of Tehran University of Medical Sciences (TUMS) laboratories before HSCT and 1 and 3 months afterwards. The cosyntropin test for all and the clonidine test for short stature patients was conducted before HSCT., Results: Before HSCT, delayed puberty and hypogonadotropic hypogonadism was found in 10% and 20% of patients, respectively. GH deficiency, low IGF1 and short stature was found in 25%, 55% and 40% of patients, respectively. Hypocortisolism, hypothyroidism and panhypopituitarism was found in 15%, 10% and 15% of patients, respectively. Prevalence of hypogonadotropic hypogonadism, low IGF1, hypothyroidism and panhypopituitarism was found in 20%, 40%, 10% and 10% of patients after 3 months, respectively (delayed puberty and short stature prevalence do not change after 3 months). HSCT caused lower T3 and estradiol and higher TSH. Corticosteroid users (15) had higher GH and lower T3 and testosterone or estradiol. Ferritin had a significant (negative) correlation with (before) prolactin and a significant correlation with T3 and T4 after HSCT. Age and acute graft-versus-host disease (GVHD) had no significant effect., Conclusion: Considering the small sample size and short duration of the study, it is difficult to reach any conclusion however it seems HSCT does not appear to have an overall positive or negative effect on prevalence of pituitary- hypothalamus axis disorders in pediatric thalassemic patients in 3 months., (© 2018 The Author(s).
