Revisiting Adrenal Crisis Triggered by Influenza Infection: Lessons from Two Fatal Cases

Abstract Adrenal crisis is a life-threatening endocrine emergency that can progress within hours despite a prior diagnosis and maintenance therapy. We describe a fatal influenza-triggered adrenal crisis in two patients: a child with panhypopituitarism and an adult with prior pituitary surgery, both presenting in cardiac arrest. Despite resuscitation and intravenous hydrocortisone, a fatal hypoxic-ischemic injury or multiorgan failure occurred. These cases highlight the fulminant course of an adrenal crisis and underscore the importance of early recognition, clinician awareness, prompt parenteral hydrocortisone administration, and reinforcement of education for patients, caregivers, and healthcare providers to improve preparedness and prevent avoidable deaths.

Organ Donation after Extracorporeal Cardiopulmonary Resuscitation: Clinical and Ethical Perspectives
JaLCDOI 10.18926/AMO/69147
FullText URL 79_4_221.pdf
Author Yumoto, Tetsuya| Naito, Hiromichi| Hongo, Takashi| Obara, Takafumi| Kosaki, Yoshinori| Ageta, Kohei| Nojima, Tsuyoshi| Tsukahara, Kohei| Nakao, Atsunori|
Abstract Extracorporeal cardiopulmonary resuscitation (ECPR) has evolved into a life-saving therapy for select cardiac arrest patients, yet a growing body of evidence suggests it also holds promise as a bridge to organ donation in non-survivors. This review explores the clinical outcomes, ethical complexities, and evolving policies surrounding organ donation after ECPR. We summarize recent international and Japanese data demonstrating favorable graft function from ECPR donors, with the exception of lung transplantation. The ethical challenges — particularly those involving brain death determination on extracorporeal membrane oxygenation and adherence to the dead donor rule — are discussed in the context of Japan’s recent regulatory reforms. Additionally, we highlight the importance of structured end-of-life communication through multidisciplinary team meetings in facilitating ethically sound transitions from rescue efforts to donation pathways. Moving forward, improvements in donor management, standardized legal frameworks, and public and professional education are essential to optimizing the life-saving and life-giving potential of ECPR.
