Efficacy and safety of single-dose anti-thymocyte globulin versus basiliximab induction therapy in pediatric kidney transplant recipients: A retrospective comparative cohort study. Pediatr Transplant 2024; 28:e14713. [PMID: 38553819 DOI: 10.1111/petr.14713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 01/11/2024] [Accepted: 01/28/2024] [Indexed: 04/02/2024]
Abstract
BACKGROUND This study aimed to compare the efficacy and safety of basiliximab (BAS) versus a single dose of anti-thymocyte globulin (r-ATG) induction therapy in pediatric kidney transplant recipients (KTRs). METHODS This single-center retrospective comparative cohort study included all pediatric KTRs from May 2013 to April 2018 and followed up to 12 months. In the first period, all recipients received BAS, while from May 2016, a single 3 mg/kg dose of r-ATG was instituted. Maintenance therapy consisted of a calcineurin inhibitor plus prednisone plus azathioprine or mycophenolate. RESULTS A total of 227 patients were included (BAS, n = 113; r-ATG, n = 114). The main combination of immunosuppressive drugs was tacrolimus, prednisone, and azathioprine in both groups (87% vs. 88%, p = .718). Patients receiving r-ATG showed superior survival-free of the composite endpoint (acute rejection, graft loss, or death; 76% vs. 61%, p = .003; HR 2.08, 1.29-3.34, p = .003) and lower incidence of biopsy-proven acute rejection (10% vs. 21%, p = .015). There was no difference in the overall incidence of CMV infection (33% vs. 37%, p = .457), PTLD (1% vs. 3%, p = .309), 30-day hospital readmissions (24% vs. 23%, p = .847), and kidney function at 12 months (86 ± 29 vs. 84 ± 30 mL/min/1.73m2, p = .614). CONCLUSIONS These data suggest that induction therapy with a single 3 mg/kg dose of r-ATG is associated with higher efficacy for preventing acute rejection and similar safety profile compared to BAS.

Clin Transplant 2022; 36:e14766. [PMID: 35822347 DOI: 10.1111/ctr.14766] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 06/21/2022] [Accepted: 06/28/2022] [Indexed: 11/26/2022]
Abstract
Neutropenia post-kidney transplantation is associated with adverse graft and patient outcomes. We aimed to analyze the effect of granulocyte colony-stimulating factor (G-CSF) use with and without immunosuppression reduction on graft outcomes in neutropenic recipients. In this retrospective cohort study, we identified 120 recipients with neutropenia, within the first-year post-transplant. Of these, 45.0% underwent no intervention, 17.5% had immunosuppression reduced, 18.3% were only given G-CSF, and 19.2% had both interventions. Overall, 61 patients experienced the composite outcome of de-novo DSA, biopsy-proven acute rejection, and all-cause graft failure and the cumulative incidence of this outcome did not vary by any of the four interventions (p = 0.93). When stratifying the cohort by G-CSF use alone, those who received G-CSF were more likely to have had severe neutropenia (<500/mm3 :51.1%vs.12.0%, p<0.001), and immunosuppression reduction (51.1%vs.28.0%, p = 0.003). However, the composite outcome was not different in the G-CSF and no G-CSF cohort (53.3%vs.49.3%, p = 0.67), and in a multivariate model, G-CSF use was not associated with this outcome (aHR = 1.18, 95%CI:0.61-2.30). However, a trend towards higher DSA production was noted in the G-CSF cohort (87.5%vs.62.2%) and this observation warrants prospective evaluation. Overall, we conclude that G-CSF use with or without immunosuppression reduction was not associated with graft outcomes. This article is protected by copyright. All rights reserved.

Predictors of Serological Response to SARS-CoV-2 Vaccination in Kidney Transplant Patients: Baseline Characteristics, Immunosuppression, and the Role of IMPDH Monitoring. J Clin Med 2022; 11:jcm11061697. [PMID: 35330022 PMCID: PMC8953201 DOI: 10.3390/jcm11061697] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 03/09/2022] [Accepted: 03/15/2022] [Indexed: 11/25/2022] Open
Abstract
Immunosuppression increases the risk of severe coronavirus disease 2019 (COVID-19). Morbidity and mortality of this disease in kidney transplant patients are higher than in the general population. As the vaccination response of transplant patients is weak, serological monitoring was performed. In this cohort study, we analyzed the determinants of vaccination response. All patients had no history of COVID-19. With anti-spike IgG monitoring, 148 responders and 415 non-responders were identified. We compared both groups using multivariate analyses of the cohort and a sub-cohort of mycophenolic-acid-treated patients. We investigated the influence of patient characteristics, immunosuppression, and erythrocyte inosine monophosphate dehydrogenase (IMPDH) activity. In responders, the time after transplantation was longer (13.5 vs. 8.5 years), the glomerular filtration rate was higher (56.9 vs. 47.8 mL/min/1.73 m2), and responders were younger (53.0 vs. 57.4 years). Heterologous vaccination was more effective than homologous vaccination. Calcineurin inhibitors plus mycophenolate reduced the seroconversion rate. No seroconversion was observed in belatacept patients. In mycophenolate-treated patients, IMPDH activity was a significantly better predictor of response than mycophenolate dose (AUC 0.84 vs. 0.62, p < 0.001). Immunosuppression strongly affects vaccine response. Modifications to immunosuppression should be considered in order to facilitate this response. Erythrocyte IMPDH activity can be used to guide mycophenolate treatment.

Decreased incidence of acute rejection without increased incidence of cytomegalovirus (CMV) infection in kidney transplant recipients receiving rabbit anti-thymocyte globulin without CMV prophylaxis - a cohort single-center study. Transpl Int 2021; 34:339-352. [PMID: 33314321 PMCID: PMC8573716 DOI: 10.1111/tri.13800] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Revised: 09/28/2020] [Accepted: 12/07/2020] [Indexed: 01/05/2023]
Abstract
Induction therapy with rabbit anti-thymocyte globulin (rATG) in low-risk kidney transplant recipients (KTR) remains controversial, given the associated increased risk of cytomegalovirus (CMV) infection. This natural experiment compared 12-month clinical outcomes in low-risk KTR without CMV prophylaxis (January/3/13-September/16/15) receiving no induction or a single 3 mg/kg dose of rATG. We used logistic regression to characterize delayed graft function (DGF), negative binomial to characterize length of hospital stay (LOS), and Cox regression to characterize acute rejection (AR), CMV infection, graft loss, death, and hospital readmissions. Recipients receiving 3 mg/kg rATG had an 81% lower risk of AR (aHR 0.14 0.190.25 , P < 0.001) but no increased rate of hospital readmissions because of infections (0.68 0.911.21 , P = 0.5). There was no association between 3 mg/kg rATG and CMV infection/disease (aHR 0.86 1.101.40 , P = 0.5), even when the analysis was stratified according to recipient CMV serostatus positive (aHR 0.94 1.251.65 , P = 0.1) and negative (aHR 0.28 0.571.16 , P = 0.1). There was no association between 3 mg/kg rATG and mortality (aHR 0.51 1.253.08 , P = 0.6), and graft loss (aHR 0.34 0.731.55 , P = 0.4). Among low-risk KTR receiving no CMV pharmacological prophylaxis, 3 mg/kg rATG induction was associated with a significant reduction in the incidence of AR without an increased risk of CMV infection, regardless of recipient pretransplant CMV serostatus.
