AbstractDelayed graft function (DGF) is a type of acute renal failure that is closely linked to the immune system. The objective of this study is to investigate immune trends during the perioperative period of renal transplantation and compare the variations between patients with DGF and immediate graft function (IGF). A total of 48 kidney transplant patients were enrolled. Parameters including stimulated adenosine triphosphatase concentrations (sATP), nonstimulated ATP concentrations, white blood cells, and lymphocyte count were assessed. Patients were categorized into the DGF or IGF group. Clinical information and changes in immune markers were compared. Receiver operating characteristic analysis was performed to determine the sensitivity and specificity in predicting DGF. Additionally, separate immune function analyses were conducted for the 3 infection cases. Following induction immunosuppressive therapy, white blood cells, and neutrophil count showed a significant initial increase followed by a gradual decline. Lymphocyte count, nonstimulated ATP concentrations, and sATP exhibited an initial significant decrease followed by a slow recovery. Immune markers between the DGF and IGF groups were significantly different at day 4 after renal transplantation. Only sATP levels at day 4 after renal transplantation (area under the curve = 0.731, sensitivity = 0.864, specificity = 0.684) demonstrated predictive value for DGF occurrence. Among the 3 infection cases, 2 cases exhibited persistently decreased sATP levels and died within the first month and 6 months, while the remaining case showed a recovery of sATP levels at D9 and survived. These findings indicate that sATP level can potentially serve as a biomarker reflecting the impact of immunosuppressants. Poor recovery of sATP may be associated with DGF, infection, or even mortality.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
