ABSTRACT The effects of intranasal insufflation of the synthetic growth hormone releasing factor GRF 1-29-NH2 on serum growth hormone (GH) were investigated in five healthy prepubertal children with short stature. 100 μg/kg/body weight of synthetic GRF 1-29-NH2, 500 μg in 100 μl water, were insufflated intranasally after careful cleaning of the nose. GRF 1-29-NH2 induced a prompt rise of serum GH levels with peak values at 15 minutes in all children investigated. Peak serum GH values were 28.3 ± 12.0 ng/ml (x̄ ± SD), range 17.1 - 47.6 ng/ml; Δ was 27.0 ± 12.2 ng/ml (x̄ ± SD). Serum GH levels were still significantly raised 120 minutes after the insufflation of GRF 1-29-NH2 (p < 0.05). No side effects, except for burning of the nasal mucosa in one patient, were observed. The results of this study demonstrate that intranasal insufflation of synthetic GRF 1-29-NH2 induces a prompt release of GH in otherwise normal children with short stature. Pulsatile intranasal insufflation of GRF 1-29-NH2 probably could be used for the treatment of some children with GH deficiency due to a defect at a suprapituitary level.
