title: Growth response in prepubertal children with idiopathic growth hormone deficiency during the first year of treatment with human growth hormone. Analysis of the Kabi International Growth Study.
abstract: In order that children with growth hormone deficiency (GHD) reach the goal of normal adult stature, treatment modalities need to be optimized. From the large database of patients enrolled in the Kabi International Growth Study (KIGS), 257 prepubertal patients with idiopathic GHD undergoing their first year of growth hormone (GH) substitution therapy were selected. A multiple regression analysis was performed to determine both auxiological factors characterizing the patients and the factors related to the chosen treatment modalities which are of significance for the observed magnitude of the growth response. Due to the structure of the data, pretreatment height velocity and bone age-derived auxiological data were not considered. It was observed that the magnitude of the growth response was inversely correlated with chronological age and relative height (HT SDS) at the start of GH treatment but was positively correlated with mid-parental height. The growth response was also positively correlated with the GH dose (IU/kg/week) and the frequency of GH injections per week. A regression equation using these five parameters was derived, allowing the growth response of these patients to be predicted. The extension of this analytical approach in the future will allow the treatment of patients with GHD to be tailored to individual requirements.
