Thyroid Stimulating Hormone and Growth Hormone Responses to Thyrotropin Releasing Hormone in Anorexia Nervosa

Ten female patients who satisfied objective criteria for the diagnosis of anorexia nervosa were given 500 ug of thyrotropin releasing hormone. Thyroid stimulating hormone and growth hormone responses were measured in duplicate by radioimmunoassay. These patients had a low normal Δ thyroid stimulating hormone but a delayed peak response. In addition, these patients had pathological growth hormone release in response to thyrotropin releasing hormone infusion. Both delayed peak thyroid stimulating hormone and growth hormone response to thyrotropin releasing hormone have been reported for patients with hypothalamic disorders.
