Objective: To summarize the experiences in high-risk renal transplant recipients for ketter long-term survival.
Methods: From April 1991 to December 2008, a total of 921 kidney recipients with high-risk factors were divided into six groups as following: (1) pediatric patients (< 18 years old) (GI, n = 34); (2) retransplant recipients (GII, n = 169); (3) high sensitized patients (PRA> 30% or peak PRA > 50%)(GIII, n = 35); (4) elderly recipients (> 60 years old) (GIV, n = 297); (5) diabetic patients (GV, n = 112); (6) patients with HBV/HCV infection or HBV/HCV carrier (GVI, n = 274). Each group was compared to a control of 807 recipients without any above risk factor for patient and graft survival at 1, 3 and 5 years. Incidences of acute rejection (AR), chronic rejection (CR) and complication were analyzed and compared respectively between the studied subjects and the control group as well.
Results: Compared with the control group, patient/graft survivals were lower in GII, GIII and GVI (all P < 0.05), GIV had worse patient survival (P < 0.05); AR and CR incidences were greater in GI and GIII (all P < 0.05); GIV, GV and GVI had more complications.
Conclusions: This study suggests the benefits for long-term outcome in high-immunological risk renal transplant recipients of low acute selection incidence rate, and reduction of complication incidences is the key to long term results for non-immunological high risk recipients.

Patterns of belatacept use and risk of post-transplant lymphoproliferative disorder in US kidney transplant recipients: An analysis of the Organ Procurement and Transplantation Network database.
PLoS One
January 2025
Worldwide Health Economics and Outcomes Research, Bristol Myers Squibb, Princeton, NJ, United States of America.
Background: Belatacept is approved for the prophylaxis of organ rejection in Epstein-Barr virus (EBV)-seropositive kidney transplant recipients and is associated with a risk of post-transplant lymphoproliferative disorder (PTLD).
Methods: Data from the Organ Procurement and Transplantation Network were used to examine patterns of belatacept use, describe patient characteristics, and estimate risk of PTLD in EBV-seropositive, kidney-only transplant recipients receiving belatacept- or calcineurin inhibitor (CNI)-based immunosuppression as part of US Food and Drug Administration-mandated safety monitoring.
Results: During the study period (June 15, 2011-June 14, 2016), 94.
Tailoring Kidney Transplant Strategies: Unraveling the Impact of Acute Kidney Injury and Preservation Methods Across Different Strata of Kidney Risk.
Clin Transplant

Division of Transplant Surgery, Department of Surgery, University of Washington, Seattle, Washington, USA.
Background: The use of donor kidneys with acute kidney injury (AKI) aims to expand the organ pool, but uncertainty remains regarding their outcomes across different Kidney Donor Profile Index (KDPI) groups and preservation methods.
Methods: We retrospectively analyzed 108 160 deceased donor kidney transplants from the OPTN database, focusing on adult recipients of kidneys from donors with or without AKI between December 2014 and December 2022. Propensity matching was used for each KDPI group (1-20, 21-59, 60-84, and 85-100), comparing donors with AKIN stages 0-1 to AKIN stages 2-3.
Examining Whole Blood, Total and Free Plasma Tacrolimus in Elderly Kidney Transplant Recipients.
Ther Drug Monit
February 2025
School of Pharmacy, University of Queensland, Brisbane, QLD, Australia.
Background: Therapeutic monitoring is routinely performed to ensure tacrolimus whole-blood concentrations fall within a predefined target. Despite this, patients still experience inefficacy and toxicity that could be related to variability in free (unbound) tacrolimus exposure. Therefore, the aim of this study was to compare tacrolimus-free plasma (C u ), total plasma (C p ), and whole-blood (C wb ) concentrations in adult kidney transplant recipients and to characterize tacrolimus disposition across different matrices.

Background: Long-term renal allograft acceptance has been achieved in macaques using a transient mixed hematopoetic chimerism protocol, but similar regimens have proven unsuccessful in heart allograft recipients unless a kidney transplant was performed simultaneously. Here, we test whether a modified protocol based on targeting CD154, CD2, and CD28 is sufficient to prolong heart allograft acceptance or promote the expansion of regulatory T cells.
Methods: Eight macaques underwent heterotopic allo-heart transplantation from major histocompatibility complex-mismatched donors.
The Difficulties of Treating Complement-3-Mediated Glomerulopathy.

Northwell, New Hyde Park, NY, Department of Medicine, Manhasset, NY.
Background: C3 glomerulopathy (C3G) is a rare disease affecting the complement alternative pathway, categorized into dense deposit disease and C3 glomerulonephritis. Dense deposit disease predominantly affects younger individuals, while C3 glomerulonephritis tends to manifest in older populations. The diseases are characterized by dysregulation of the complement alternative pathway, leading to the deposition of complement components in the glomeruli and subsequent renal dysfunction.
