Abstract
Long-acting growth hormone (LAGH) is emerging to be a new preparation for treatment of short stature. We aimed to determine whether 12-month treatment with LAGH in patients with idiopathic short stature has an effect on the nocturnal endogenous growth hormone (GH) secretion and metabolic consequences and efficacy. Participants included 10 GH-naïve prepubertal children with idiopathic short stature (ISS). One patient was withdrawn due to own decline during study. Participants were randomized on a 1:1 ratio to receive either a daily GH (0.37 mg/kg/week) or once-weekly LAGH (0.7 mg/kg/week) over a 12-month period. Nocturnal endogenous GH secretory profiles obtained from 12-h blood samplings at 30-min interval were assessed at baseline and 2 weeks after the completion of GH treatment. Post-treatment changes in height velocity, height standard deviation score (SDS), metabolic parameters, and adverse events were measured. A total of 4 patients received LAGH, and 5 patients received daily GH. Nocturnal endogenous GH secretory profiles, such as mean serum GH concentrations, frequency, amplitude, interpulse interval of spontaneous GH secretory bursts, and mass of GH released per secretory burst were similar at baseline and after 12-month treatment in both groups. The efficacy and safety after LAGH treatment for 12 months were similar to those of daily GH. In conclusions, these findings indicated that LAGH does not suppress endogenous GH secretion, and can be used for treatment of non-GH deficient short stature with similar efficacy and safety compared to daily GH. These may contribute to define and develop treatment and follow-up protocols for LAGH use in ISS patients.
期刊介绍:
Growth Hormone & IGF Research is a forum for research on the regulation of growth and metabolism in humans, animals, tissues and cells. It publishes articles on all aspects of growth-promoting and growth-inhibiting hormones and factors, with particular emphasis on insulin-like growth factors (IGFs) and growth hormone. This reflects the increasing importance of growth hormone and IGFs in clinical medicine and in the treatment of diseases.
