Effect of hydrocortisone on intravenous glucose tolerance in small-for-gestational-age infants

The effects of hydrocortisone (H) hemisuccinate (10 mg/kg) on intravenous glucose tolerance (1 g/kg) was studied in eight full term small-for-gestational-age (SGA) infants and compared to seven control infants at mean age of 41 h. After H, the rate of glucose disappearance was (mean +/- SD) 0.92 +/- 0.27 vs 1.24 +/- 0.31% min in controls (p less than 0.01). Glucose space was similar after H: 449 +/- 62 ml/kg and in the control group 468 +/- 75 ml/kg. At 5 and 15 min, although higher in the H group, mean plasma glucose was not significantly different. The difference became significant at 30 min (t = 2.00; p = 0.05), 45 (t = 2.298; p less than 0.05) and 60 min (t = 2.48; p less than 0.02). Plasma insulin concentration did not change after glucose injection in the control group. After H administration, plasma insulin increased: the basal median value was less than 5 mU/ml (range less than 5-18) and at 60 min it rose to 30 mU/ml (range 7.5-89). These data suggest that in newborn infants corticoids induce a reduced peripheral uptake of glucose independent of insulin secretion.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
