Neonatale Hypoglykämie bei angeborener isolierter Aplasie der Adenohypophyse

Abstract

We report a female newborn with prolonged neonatal hypoglycaemia and vomiting. Endocrinologic studies demonstrated the absence of the anterior pituitary hormones ACTH, STH, LH, FSH, and PRL while TSH basal secretion as well as TSH stimulation were normal at the age of 2 months. Magnetic resonance imaging showed aplasia of the anterior pituitary and a nodular ectopic posterior lobe. Substitution with prednisone resulted in normalization of blood glucose values with clinical improvement of the patient. At the age of 8 months the patient was started on recombinant human growth hormone due to poor growth; with 10 months decrease of thyrotropin secretion resulted in additional thyroxine replacement therapy.
