title: [Severe chronic anemia and endocrine disorders in children].
abstract: Hemolytic anemias can induce various anomalies of the endocrine glands which can already be observed in children. Endocrine dysfunction is also found in the course of therapy for aplastic anemias, usually as undesirable side effects. In Europe, 2-9% of the population belongs to ethnic minorities at risk for developing hemolytic anemia. Pituitary affinity to iron deposition explains the high incidence of hypogonadism, puberty delay and growth retardation although other factors have to be considered. Growth hormone deficiency has to be ruled out as it can occur in a minority of subjects with thalassemia and sickle-cell disease (drepanocytosis). Diabetes mellitus, hypothyroidism and hypoparathyroidism may also develop. Follow-up includes close monitoring of growth and pubertal development in order to guide therapeutic interventions.
