Insights

Calcium channel blockers may treat persistent hyperinsulinemic hypoglycemia of infancy (PHHI). A 30-day-old infant with PHHI was successfully treated with oral nifedipine alone.

Area of Science:

  • Neonatal Medicine
  • Pediatric Endocrinology

Background:

  • Persistent hyperinsulinemic hypoglycemia of infancy (PHHI) is a rare but serious condition.
  • Current treatment options for PHHI can be invasive or have significant side effects.

Observation:

  • A 30-day-old infant presented with symptoms of PHHI.
  • The infant's condition was refractory to initial management.

Findings:

  • Successful treatment of PHHI was achieved using oral nifedipine.
  • Nifedipine, a calcium channel blocker, demonstrated efficacy as a sole therapeutic agent.

Implications:

  • Oral nifedipine represents a potential novel therapeutic strategy for PHHI.
  • This finding may reduce the need for more aggressive interventions in infants with PHHI.
