Abstract. Massi-Benedetti, F., Marini, A., Caccamo, M. L. and Falorni, A. (Paediatric Clinic of the University of Perugia and the Service of Neonatal Pathology of the University of -Milan, Italy). Blood glucose and plasma insulin and glucagon response during intravenous glucose tolerance test in newborn infants affected by erythroblastosis foetalis. Acta Paediatr Scand, 64:113, 1975.–Intravenous glucose injection (1 g/kg b.w.) was performed in eight newborn infants affected by erythroblastosis foetalis (IEF) and in seven controls during the first day of life in order to study insulin and glucagon response. The IEF infants were affected by mild or moderate hemolytic disease and their blood glucose values and plasma insulin concentrations before and throughout the test did not differ significantly from those of the controls. After the glucose injection the plasma glucagon concentrations showed great variations in both groups. The control infants did not show any significant changes; in the IEF infants, significant decreases were seen at 3 and 20 min of the test. These data seem to indicate that the alpha-cell sensitivity to glucose is greater in IEF than in normal infants and is not dependent on the development of the glucose-mediated insulin release mechanism. |
