Abstract [en]

P>Context Few studies have evaluated the metabolic outcomes of growth hormone (GH) treatment in idiopathic short stature (ISS). Moreover, children with ISS appear to need higher GH doses than children with GH deficiency (GHD) to achieve the same amount of growth and may therefore be at increased risk of adverse events during treatment. The individualized approach using prediction models for estimation of GH responsiveness, on the other hand, has the advantage of narrowing the range of growth response, avoiding too low or high GH doses. Design Short prepubertal children with either isolated GHD (39) or ISS (89) participated in a 2-year randomized trial of either individualized GH treatment with six different GH doses (range, 17-100 mu g/kg/day) or a standard dose (43 mu g/kg/day). Objective To evaluate if individualized GH treatment reduced the variance of the metabolic measures as shown for growth response and to compare changes in metabolic variables in children with ISS and GHD. Hypothesis Individualized GH dose reduces the range of metabolic outcomes, and metabolic outcomes are similar in children with ISS and GHD. Results We observed a narrower variation for fasting insulin (-34 center dot 2%) and for homoeostasis model assessment (HOMA) (-38 center dot 9%) after 2 years of individualized GH treatment in comparison with standard GH dose treatment. Similar metabolic changes were seen in ISS and GHD. Delta (delta) height SDS correlated with delta insulin-like growth factor I (IGF-I), delta leptin and delta body composition. Principal component analysis identified an anabolic and a lipolytic component. Anabolic variables [delta lean body mass (LBM) SDS and delta IGF-I SDS] clustered together and correlated strongly with delta height SDS and GH dose, whereas lipolytic variables [delta fat mass (FM) SDS and delta leptin] were clustered separately from anabolic variables. Regression analysis showed GH dose dependency in ISS, and to a lesser degree in GHD, for delta LBM SDS and delta height SDS, but not for changes in FM. Conclusions Individualized GH dosing during catch-up growth reduces the variance in insulin and HOMA and results in equal metabolic responses irrespective of the diagnosis of GHD or ISS.
