Abstract Objectives Hyperinsulinism is the most common cause of recurrent hypoglycemia in infants, with transient and permanent forms. Currently, there are no effective tools to predict severity and time to resolution in infants with transient hyperinsulinism (tHI). Therefore, our objective was to assess whether early glucose trends predict disease duration in tHI. Methods A retrospective, pilot cohort of infants admitted with tHI was phenotyped for clinical and laboratory parameters. Blood glucose (BG) values were collected from the first documented hypoglycemia for 120 h (five days). Results In 27 neonates with tHI, the presence of fetal distress (p=0.001) and higher mean daily BG (p=0.035) were associated with shorter time to resolution of hypoglycemia. In a further sensitivity analysis that grouped the cohort by the presence or absence of fetal distress, we found that in neonates without fetal distress, lower mean daily glucose was associated with longer disease duration (R2=0.53, p=0.01). Conclusions Our pilot data suggests that predictors for disease duration of tHI may be elicited in the first week of life, and that tHI associated with fetal distress may represent a distinct clinical entity with a shorter time course.
