Solid organ transplant recipients have an up to ninefold higher risk of varicella-zoster virus (VZV) reactivation than the general population. Due to lifelong immunosuppressive therapy, vaccination against VZV may be less effective in kidney transplant (KTX) recipients. In the current study, twelve female and 17 male KTX recipients were vaccinated twice with the adjuvanted, recombinant zoster vaccine Shingrix™, which contains the VZV glycoprotein E (gE). Cellular immunity against various VZV antigens was analyzed with interferon-gamma ELISpot. We observed the strongest vaccination-induced changes after stimulation with a gE peptide pool. One month after the second vaccination, median responses were 8.0-fold higher than the responses prior to vaccination ( = 0.0006) and 4.8-fold higher than responses after the first vaccination ( = 0.0007). After the second vaccination, we observed an at least twofold increase in ELISpot responses towards gE peptides in 22 out of 29 patients (76%). Male sex, good kidney function, early time point after transplantation, and treatment with tacrolimus or mycophenolate were correlated significantly with higher VZV-specific cellular immunity, whereas diabetes mellitus was correlated with impaired responses. Thus, our data indicate that vaccination with Shingrix™ significantly augmented cellular, VZV gE-specific immunity in KTX recipients, which was dependent on several covariates.

The results of kidney transplantation (KTx) in elderly patients are deteriorated by more frequent use of organs procured from older or extended criteria donors (ECDs). To eliminate the influence of donor factors on the transplantation results, the pair analysis method was applied. The study aimed to assess the survival, during long-term follow-up after transplantation, of recipients and transplanted kidneys, graft function, and factors influencing survival in recipients aged 60 years and older (≥60) compared to recipients aged less than 60 years (<60) who received a kidney from the same brain death donor (DBD).

Introduction: The incidence of mortality late in the pandemic, particularly after widespread vaccine availability, is not well understood. Herein, we elucidate the effect of this impact of the COVID pandemic as well as risk factors for mortality during it.
Methods: The primary end point was death with a functioning graft with secondary endpoints of mortality rates in subgroups and at different time intervals during the pandemic.

Purpose: The objective of this study was to evaluate the perioperative outcomes and complications associated with the use of acetylsalicylic acid (ASA) in deceased donor kidney transplantation (KTX), with a particular focus on bleeding events.
Methods: We retrospectively analyzed 157 kidney transplant recipients (KTRs) who underwent KTX at Charité Berlin, Department for Urology, between February 2014 and December 2017. Patients were divided into two groups: patients with ASA in their preoperative medication (Group A, n = 59) and patients without ASA use (Group B, n = 98).

Background: Graft loss is a major health concern for kidney transplant (KTx) recipients. It is of clinical interest to develop a prognostic model for both graft function, quantified by estimated glomerular filtration rate (eGFR), and the risk of graft failure. Additionally, the model should be dynamic in the sense that it adapts to accumulating longitudinal information, including time-varying at-risk population, predictor-outcome association, and clinical history.

Introduction: Atrial fibrillation (AF) in end-stage kidney disease (ESKD) and kidney transplant (KTx) recipients presents challenges in stroke risk management. This study aimed to compare hospitalization rates for ischemic and hemorrhagic cerebrovascular events in ESKD and KTx patients with and without AF.
Methods: Using the National Inpatient Sample (2005-2019), retrospective analysis was conducted on hospitalizations for ESKD and KTx patients with and without AF.
