The hypoxia, associated to intra-uterine growth restriction, is related to high concentrations of IGFBP1 and unchanged concentrations of IGF1 in animals. Nevertheless, during threatening life events, low IGFI concentrations and high IGFBP1 concentrations was reported. Furthermore, severe hypoxia increased the IGF1R expression of the neuronal growth cones in the ovine fetal brain. No information is available regarding the regulation of the IGF system by the acute hypoxia in hum...

The aim of this study was to analyze IGF1R gene expression in patients with idiopathic short stature (ISS) and correlate it with their GH and IGF1 status. In a previous study, we reported lower final height in subjects with ISS and GH peak ≥40 mU/l (Group1, n=16) compared to those with ISS and GH peak between 20 and 40 mU/l (Group2, n=15), after stimulation test (ITT) performed before or during puberty. Patients were 16–24 (Group1) and 15–26 (Grou...

Background: HIV-infected paediatric patients usually show impaired growth. Data reporting abnormalities in GH–IGF–IGFBPs system are scarce and inconclusive.Aim: To analyse blood concentration of the major components of IGF–IGFBPs system in these children and compare them to growth parameters and to cytokines levels.Methods: prepubertal HIV-infected children, aged 8.2±1.7 years, were evaluated every 6 months duri...

Cretinism and neurological impairment are related to primary hypothyroidism (PHT) while children with central hypothyroidism (CHT) are usually diagnosed during the investigation process for short stature.Objective: To describe two children with unusual presentation of CHT.Case 1: Baby girl, born after 38 weeks of gestation, weighing 3000 g, and measuring 49.5 cm long was admitted when 3 months old. The parents reported stunted neur...
