Key Laboratory of Endocrinology of the Ministry of Health Department of Endocrinology Peking Union Medical College Hospital Chinese Academy of Medical Sciences and Peking Union Medical College Beijing China Summary Adult growth hormone deficiency GHD mainly defined by a series of nonspecific clinical manifestations and relevant biomarkers is well-recognized as structural or functional damage in hypothalamus and / or pituitary gland. Due to pulsatile secretion of growth hormone GH and variations among random population differentiation of patients with GHD and normal individuals should not be made simply depending on the level of GH. The well-acknowledged insulin tolerance test ITT remains the gold standard for diagnosis of GHD in a- dults and it is not until recently when the combination of growth hormone releasing hormone GHRH and arginine test as well as the combination of GHRH with growth hormone releasing peptide GHRP and glucagon stimulating test are considered to share similar diagnostic value with ITT. Multiple complications are common in adults with GHD among which chronic cardiovascular complications might be the chief cause for increased mortality rate. Recombinant human growth hormone rhgh replacement therapy could improve most of the clinical endpoint events including elevation of quality of life and reduction in the risk of cardiovascular events.
