Serum IGFBP-2 Concentration in Neonates with Potential Diagnosis of Growth Hormone Deficiency (GHD)

Gabriela Ballerini Maria , Braslavsky Debora , Keselman Ana , Eugenia Rodriguez Maria , Gotta Gabriela , Gabriela Ropelato Maria , Bergada Ignacio

In a retrospective study (1), we found that a GH<6.5 μg/L, IGF-I-WHO87/518 <30 μg/L and IGFBP-3<0.8 μg/mL confirmed GHD diagnosis with high diagnostic accuracy in neonates with clinical suspicion of GHD. GH and insulin negatively regulate IGFBP-2, and it was proposed to reflect GH status in the diagnostic work-out of GHD in childhood and adults. The accuracy of IGFBP-2 has not been set for neonates.Objective: To prospectively v...

Microalbuminuria and Glomerular Filtration Rate in SGA Born Young Adults

Goedegebuure Wesley , Hokken-Koelega Anita

Background: Following Barker’s hypothesis on fetal growth retardation, low birth weight and being born small for gestational age (SGA) might be linked to fewer glomeruli which influences adult disease. Growth hormone (GH) treatment leads to a greater kidney length and total kidney volume, as well as a higher glomerular filtration rate (GFR). Microalbuminuria, defined as more than 20 mg/l albumin in random urine sample, is a marker for renal diseases and is a risk factor f...
