The Renal Histopathological Findings in Patients with Renal Allograft Dysfunction: A Retrospective Single Center Study.
Introduction: Despite many advances in the development of knowledge and application of new immunosuppressive medications over the past two decades, the improvement has only been seen in the short-term outcome of kidney transplantation while the long-term survival of kidney transplantation has not significantly improved. Allograft kidney biopsy may help to determine the causes of allograft dysfunction which may change the treatment strategy.
Methods: In this retrospective study, kidney transplant recipients who underwent kidney biopsy in Shariati hospital during the years 2004 to 2015, at least three months after the kidney transplantation, were included for evaluation. Chi-square, ANOVA, post-hoc LSD, and T-test were used for data analysis.
Results: A total number of 525 renal transplant biopsies were performed; 300 of them had complete medical records. The reported pathologies consisted of acute T-Cell mediated rejection (TCMR) (17%), interstitial fibrosis and tubular atrophy/chronic allograft nephropathy (IFTA/CAN) (15%), calcineurin inhibitor (CNI) nephrotoxicity (12.8%), borderline changes (10.3%), glomerulonephritis (GN) (8.9%), antibody mediated rejection (ABMR) (6.7%), transplant glomerulopathy (TG) (5.3%), normal (8.4%), and other pathologies (15.6%). C4d was positive in 19.9% of the biopsies. The pathology category had a significant correlation with allograft function (P < .001), but it had no significant relationship with age and gender of the recipient, donor and donor source (P > .05). Moreover, in about 50% of cases, treatment interventions were based on pathological results, which were effective in 77% of cases. The two-year graft and patient survival after kidney biopsy were 89% and 98%, respectively.
Conclusion: Acute TCMR, IFTA/CAN, CNI nephrotoxicity were the most common causes of allograft dysfunction based on the transplanted kidney biopsy. In addition, pathologic reports were helpful for proper treatment. DOI: 10.52547/ijkd.7256.
期刊介绍：
The Iranian Journal of Kidney Diseases (IJKD), a peer-reviewed journal in English, is the official publication of the Iranian Society of Nephrology. The aim of the IJKD is the worldwide reflection of the knowledge produced by the scientists and clinicians in nephrology. Published quarterly, the IJKD provides a new platform for advancement of the field. The journal’s objective is to serve as a focal point for debates and exchange of knowledge and experience among researchers in a global context. Original papers, case reports, and invited reviews on all aspects of the kidney diseases, hypertension, dialysis, and transplantation will be covered by the IJKD. Research on the basic science, clinical practice, and socio-economics of renal health are all welcomed by the editors of the journal.
