Turner's Syndrome Associated with Growth Hormone Deficiency

Abstract

11 out of the 13 children with Turner's syndrome currently attending our endocrine clinic were investigated for possible growth hormone deficiency. The parents of two of the 13 children refused permission for these studies. One child had inadequate hypoglycaemia and the test was not repeated. Six of the ten children with adequate hypoglycaemia had an adequate growth hormone response to hypoglycaemia, while 4 children did not. This contradicts several previous studies on children with Turner's syndrome, which have reported normal growth hormone responses to provocative tests. In the normal population approximately one in 15 has an inadequate growth hormone response to hypoglycaemia.
