Summary

Severe hyperinsulinism (HI) in premature infants is a serious condition causing recurrent hypoglycemia. This study highlights that HI in preterm infants may present as a more aggressive illness, requiring consideration in differential diagnoses.

Area of Science:

  • Neonatology
  • Pediatric Endocrinology
  • Metabolic Disorders

Background:

  • Hyperinsulinism in infancy (HI) is a primary cause of severe hypoglycemia in newborns.
  • Typically observed in term infants, HI in premature infants is rarely reported.

Purpose of the Study:

  • To report on the occurrence and characteristics of severe persistent hyperinsulinism in a cohort of prematurely born infants.
  • To assess the clinical presentation and management challenges of HI in preterm neonates.

Main Methods:

  • Case series report of seven infants born between 31-36 weeks gestation.
  • Clinical data including gestational age, birth weight, and management difficulties were analyzed.

Main Results:

  • Seven premature infants (31-36 weeks gestation) presented with severe persistent hyperinsulinism.

  • Two infants were large for gestational age; all cases were difficult to manage.
  • This suggests a potentially more aggressive form of HI in the context of prematurity.

    • Conclusions:

    • Hyperinsulinism in infancy should be considered in the differential diagnosis of severe hypoglycemia in preterm infants.
    • The association of HI with prematurity may indicate a more severe clinical course.
    • Early recognition and management are crucial for affected preterm neonates.
