title: Abnormalities in growth hormone and insulin release in short but otherwise normal patients. The arginine-insulin-glucose (AIGT) stimulation and suppression test.
abstract: Arginine-insulin stimulation and IV glucose suppression (AIGT) tests were used to evaluate release of insulin and growth hormone. Adult patients responded normally. Hypopituitary patients showed no hGH response. One third of short normal patients showed abnormal hGH responses to glucose suppression. Two thirds of the short normal patients showed poor insulin responses to either amino acid or glucose stimulation. Such patients might have abnormalities in release mechanisms for insulin and suppression mechanisms for hGH and this might contribute to their growth failure.
