title: Response to growth hormone-releasing hormone in adult renal failure patients on hemodialysis.
abstract: Exogenous synthetic growth hormone-releasing hormone (GHRH [hpGRF-40]), 1 microgram/kg body weight, was administered intravenously (IV) to eight men with chronic renal failure on chronic hemodialysis and to seven men matched for age (control group). Basal and stimulated growth hormone (GH) concentrations following GHRH (hpGRF-40) in renal failure patients were significantly higher than in controls. Basal prolactin and somatomedin C/insulin-like growth factor-1 (SmC/IGF-1) concentrations were significantly higher in the renal failure patients compared with controls. Following GHRH there was no further increase in serum concentration of thyroid-stimulating hormone (TSH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin, SmC/IGF-1, or cortisol. GH appears to be the only pituitary hormone where there is an exaggerated response to its specific releasing hormone in adults with renal failure.
