Persistent Chronic Active T-Cell-Mediated Rejection After Kidney Transplantation Is Associated With Poor Allograft Survival
Introduction
Histopathological findings of chronic active T-cell-mediated rejection (CA-TCMR) have been reported to potentially improve with treatment. However, whether this improvement is associated with a better renal prognosis remains unclear. This study was performed to analyze the impact of the histological response to therapy on kidney allograft survival in patients with CA-TCMR.
Methods
The data of patients diagnosed with CA-TCMR between January 2018 and May 2023 were retrospectively reviewed. A composite graft endpoint was defined as a two-fold increase in the serum creatinine level or the development of end-stage kidney disease.
Results
Thirty-seven patients with CA-TCMR underwent 46 follow-up biopsies. Eleven patients who were diagnosed with CA-TCMR at the last biopsy were classified as the persistent group, while the remaining 26 patients were classified as the transient group. Both before and after treatment, there were no significant changes in serum creatinine, estimated glomerular filtration rate, or proteinuria in either group. However, the transient group showed a significant reduction in interstitial fibrosis and tubular atrophy without a specific etiology (IFTA). This improvement was attributed to better histopathological Banff scores after treatment. Patients with persistent CA-TCMR had significantly worse graft survival than those with transient CA-TCMR (p = 0.002), even after adjusting for significant clinical factors (hazard ratio: 11.4; 95% CI: 1.1–120.0; p = 0.043).
Conclusion
Our findings suggest that the persistence of histopathologic evidence of CA-TCMR after treatment is a significant risk factor for allograft loss compared with transient CA-TCMR.
期刊介绍：
Clinical Transplantation: The Journal of Clinical and Translational Research aims to serve as a channel of rapid communication for all those involved in the care of patients who require, or have had, organ or tissue transplants, including: kidney, intestine, liver, pancreas, islets, heart, heart valves, lung, bone marrow, cornea, skin, bone, and cartilage, viable or stored.
Published monthly, Clinical Transplantation’s scope is focused on the complete spectrum of present transplant therapies, as well as also those that are experimental or may become possible in future. Topics include:
Immunology and immunosuppression;
Patient preparation;
Social, ethical, and psychological issues;
Complications, short- and long-term results;
Artificial organs;
Donation and preservation of organ and tissue;
Translational studies;
Advances in tissue typing;
Updates on transplant pathology;.
Clinical and translational studies are particularly welcome, as well as focused reviews. Full-length papers and short communications are invited. Clinical reviews are encouraged, as well as seminal papers in basic science which might lead to immediate clinical application. Prominence is regularly given to the results of cooperative surveys conducted by the organ and tissue transplant registries.
Clinical Transplantation: The Journal of Clinical and Translational Research is essential reading for clinicians and researchers in the diverse field of transplantation: surgeons; clinical immunologists; cryobiologists; hematologists; gastroenterologists; hepatologists; pulmonologists; nephrologists; cardiologists; and endocrinologists. It will also be of interest to sociologists, psychologists, research workers, and to all health professionals whose combined efforts will improve the prognosis of transplant recipients.
