Hormone replacement therapy, including vasopressin and corticosteroids, is widely used to stabilize donor hemodynamics; however, its impact on organ procurement remains uncertain. This study aimed to evaluate the association between vasopressin, corticosteroid therapy, and organ yield among donors who were brain-dead.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a multicenter, retrospective analysis of the Japan Comprehensive Process for End-of-Life Care and Organ Donation after Brain Death (J-RESPECT) cohort, including data from 16 institutions in Japan between 17 July 2010 and 31 December 2023. Donors were classified into high-yield (\u2265 6 organs) and low-yield (\u2264 5 organs) groups based on the median number of organs procured. Vasopressin and corticosteroid doses were categorized, and generalized estimating equations were applied to assess associations with high-yield procurement and organ-specific donation, adjusting for donor characteristics and clinical variables.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The median donor age was 47 years, 92 donors (45.1%) were female, and the median time from admission to procurement was 10 days.

After adjustment for donor characteristics, concurrent catecholamine support, and the number of organs requested by the family, low-dose methylprednisolone (&lt; 15 mg\/kg\/day) was associated with higher odds of high-yield organ procurement (odds ratios, 2.86; 95% confidence intervals, 1.45\u20135.63), whereas vasopressin dose was not. In exploratory organ-specific analyses, high-dose methylprednisolone (\u2265 15 mg\/kg\/day) was associated with left lung procurement, whereas no consistent associations were observed for other organs.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In this multicenter cohort study, low-dose methylprednisolone, but not vasopressin dose, was associated with higher organ yield after adjustment for important clinical confounders.
