Abstract
A 12-year old girl was admitted to our hospital for evaluation of her short stature. Her height was below -3.5 SD of the mean height for her age. She was diagnosed as having craniopharyngioma and treated surgically. Thereafter she was treated with thyroxine and hydrocortisone. One and a half years later, she revisited our hospital for treatment of short stature. Her plasma GH did not respond to insulin-induced hypoglycemia but increased after hGRF-44 administration, indicating hGRF deficiency. hGRF was therefore administered at a dosage of 100μg twice a day subcutaneously for three months. Her height increased 1.6 cm during treatment, which corresponded to a height increase of 6.4cm/year.
These findings indicate that hGRF treatment stimulates height increase in patients with GRF deficiency. For complete evaluation of hGRF therapy, further studies will be required.
