Insights

Low-dose hydrocortisone did not improve survival without bronchopulmonary dysplasia (BPD) in all infants. However, it significantly reduced mortality and improved survival without BPD in infants with histologic chorioamnionitis.

Area of Science:

  • Neonatal Medicine
  • Pediatric Critical Care
  • Endocrinology

Background:

  • Infants with bronchopulmonary dysplasia (BPD) exhibit diminished cortisol response to adrenocorticotropic hormone.
  • Pilot studies suggested low-dose hydrocortisone may improve survival without BPD, especially in infants with histologic chorioamnionitis.

Purpose of the Study:

  • To evaluate the efficacy of low-dose hydrocortisone for prophylaxis of early adrenal insufficiency in mechanically ventilated infants.
  • To determine the impact of hydrocortisone on survival without BPD and other clinical outcomes.

Main Methods:

  • A multicenter, randomized, masked trial involving mechanically ventilated infants (500-999 g birth weight).
  • Infants received either placebo or hydrocortisone (1 mg/kg/day for 12 days, then 0.5 mg/kg/day for 3 days).
  • BPD was defined clinically and physiologically at 36 weeks' postmenstrual age.

Main Results:

  • Enrollment stopped early due to increased gastrointestinal perforation in the hydrocortisone group.
  • Overall survival without BPD, mortality, and growth parameters were similar between groups.
  • In infants with histologic chorioamnionitis, hydrocortisone significantly decreased mortality and improved survival without BPD.

Conclusions:

  • Prophylactic hydrocortisone did not improve overall survival without BPD.
  • Hydrocortisone treatment significantly benefited infants exposed to histologic chorioamnionitis.
  • Low-dose hydrocortisone did not suppress adrenal function or impair short-term growth; however, concurrent use with indomethacin should be avoided due to increased gastrointestinal perforation risk.
