Insights

Hormone replacement therapy (HRT) significantly increases organ donation rates in patients with catastrophic brain injury (CBI). A standardized HRT protocol could maximize organ recovery in trauma patients.

Area of Science:

  • Trauma Surgery
  • Neurosurgery
  • Organ Donation Science

Background:

  • Catastrophic brain injury (CBI) leads to physiological derangements, potentially preventing organ donation in one-third of donors.
  • Hormone replacement therapy (HRT) shows promise in mitigating CBI-related organ damage.
  • No standardized HRT protocol exists for trauma centers, hindering its widespread application.

Purpose of the Study:

  • To investigate the association between HRT and organ donation in CBI patients.
  • To identify which hormone combinations are most beneficial for increasing organ donation rates.

Main Methods:

  • A prospective, observational, multicenter trial (EAST multicenter trial) involving 1,184 adult CBI patients across 38 trauma centers.
  • Generalized linear mixed model (GLMM) analysis to assess the association of HRT with organ donation, controlling for demographic and clinical factors.
  • Data collected from January 2022 to June 2025.

Main Results:

  • Of 1,184 CBI patients, 704 received HRT, and 227 of 269 organ donors received HRT.
  • Single-hormone HRT (steroids, levothyroxine, vasopressin, dopamine, DDAVP, insulin) was associated with increased odds of organ donation.
  • The combination of methylprednisolone and levothyroxine demonstrated the greatest increase in organ donation odds.

Conclusions:

  • HRT administered before brain death significantly increases the likelihood of organ donation in CBI patients.
  • Implementing a standardized HRT protocol in trauma centers is recommended to maximize organ recovery.
  • This approach can optimize organ availability for patients requiring transplants.
