[PMID: 36114044 DOI: 10.1016/j.transproceed.2022.07.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 06/25/2022] [Accepted: 07/14/2022] [Indexed: 12/01/2022]
Abstract
BACKGROUND Delayed graft function (DGF) is a serious complication associated with worsening outcomes in kidney transplantation. To facilitate DGF risk reduction, this study aimed to identify the incidence and modifiable risk factors of this condition in kidney transplant patients. METHODS This retrospective chart review included 220 patients who underwent kidney transplants between 2012 and 2021 at our kidney transplant center. Delayed graft function was defined as the requirement of hemodialysis within a week of transplantation. Clinical data from patients with DGF and those without this condition were compared to identify risk factors of DGF. RESULTS Of 205 eligible patients, 20 (9.76%) developed DGF. In the univariate analysis, high hemoglobin level, deceased-donor type, and longer warm and cold ischemic times were significantly associated with DGF (P < .05). In the variable selection in logistic regression analysis, high hemoglobin level, with a cutoff value of 11.35 g/dL, and deceased-donor transplants were associated with higher DGF incidence (P < .05 for both factors). CONCLUSIONS Our findings newly demonstrated that DGF occurred more frequently in patients with hemoglobin level >11.35 g/dL. As such, improvement in kidney transplantation outcomes could be achieved by reducing this modifiable risk factor.

Long Hemodialysis Duration Predicts Delayed Graft Function in Renal Transplant Recipients From Living Donor: A Single-Center Study. Transplant Proc 2021; 53:1477-1483. [PMID: 34006381 DOI: 10.1016/j.transproceed.2021.03.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 03/06/2021] [Accepted: 03/17/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND This study aims to determine the ratio of delayed graft function in renal transplant recipients from living donors and the predictive value of hemodialysis time before transplant for delayed graft function. METHODS We conducted a study on 116 adult patients who were diagnosed with end-stage kidney disease and were treated with hemodialysis and transplanted kidneys from living donors for 2 years (from June 2018 to June 2020). Delayed graft function event was collected for each patient. RESULTS The recipients had a median age of 36.5 years old, in which 55.2% of them were men, 4.3% of them had the diabetic mellitus, and the median hemodialysis duration was 6 months. The ratio of positive panel-reactive antibody was 33.6% and vascular reconstruction of the donor's kidney was 16.4%. The ratio of delayed graft function was 12.2% (14 of 116 patients). Delayed graft function significantly related to positive panel-reactive antibody, long duration of hemodialysis before transplant, and vascular reconstruction of donor's kidney with P < .001. Duration of hemodialysis before kidney transplant had a predictive value for delayed graft function (area under the curve, 0.83; P < .001). CONCLUSION Delayed graft function was not rare in renal transplant recipients from living donors. Duration of hemodialysis before kidney transplant was a good predictor for delayed graft function.

Abstract
OBJECTIVE The purpose of this study is to analyze varying predictive factors for improved graft function among renal transplant recipients. METHODS Two hundred eleven consecutive donor and recipient pairs who underwent renal transplantation between January 2011 and December 2015 were enrolled in our study. Factors that affected renal graft function were analyzed. Statistical analyses were performed using SPSS version 16.0 software (SPSS Inc, Chicago, IL, United States). RESULTS The mean age of donors in years was 30 (range, 17-62), with a mean body mass index (BMI) of 23.20 kg/m2 (range, 16.10-39.50). Mean total warm ischemic time in minutes was 44.80 (range, 26.10-83.45). The mean age of the recipients in years was 48 (range, 12-78) with a mean BMI of 22 kg/m2 (range, 14.80-37.30). Estimated glomerular filtration rate at 6 and 12 months post-transplantation were 69 mL per minute per 1.73 m2 (range, 10-137) and 65 (range, 16-110), respectively. Based on several parameters, there was no significant factor that improved renal graft function at 6 and 12 months after transplant. Total warm ischemic time almost showed statistical significance in predicting improved renal graft function after transplant. Future study with a longer period of observation and a larger sample size should be done for further investigation. CONCLUSIONS Total warm ischemic time is a promising parameter to predict improved renal graft function post-transplantation.

Abstract
Dendritic cells (DCs) are highly specialized, bone marrow (BM)-derived antigen-processing and -presenting cells crucial to the induction, integration and regulation of innate, and adaptive immunity. They are stimulated by damage-associated molecular patterns (DAMPS) via pattern recognition receptors to promote inflammation and initiate immune responses. In addition to residing within the parenchyma of all organs as part of the heterogeneous mononuclear phagocyte system, DCs are an abundant component of the inflammatory cell infiltrate that appears in response to ischemia reperfusion injury (IRI). They can play disparate roles in the pathogenesis of IRI since their selective depletion has been found to be protective, deleterious, or of no benefit in mouse models of IRI. In addition, administration of DC generated and manipulated ex vivo can protect organs from IRI by suppressing inflammatory cytokine production, limiting the capacity of DCs to activate NKT cells, or enhancing regulatory T cell function. Few studies however have investigated specific signal transduction mechanisms underlying DC function and how these affect IRI. Here, we address current knowledge of the role of DCs in regulation of IRI, current gaps in understanding and prospects for innovative therapeutic intervention at the biological and pharmacological levels.

Abstract
BACKGROUND Kidney transplantation holds much promise as a treatment of choice for patients with end-stage kidney disease. The impact of cold ischemia time (CIT) on acute renal transplant rejection (ARTR) remains to be fully studied in a large cohort of renal transplant patients. METHODS From the Organ Procurement and Transplantation Network database, we analyzed 63 798 deceased donor renal transplants performed between 2000 and 2010. We assessed the association between CIT and ARTR. We also evaluated the association between recipient age and ARTR. RESULTS Six thousand eight hundred two (11%) patients were clinically diagnosed with ARTR. Longer CIT was associated with an increased risk of ARTR. After multivariable adjustment, compared with recipients with CIT < 12 hours, the relative risk of ARTR was 1.13 (95% confidence interval, 1.04-1.23) in recipients with CIT ≥ 24 hours. The association of CIT and ARTR was more pronounced in patients undergoing retransplantation: compared with recipients with CIT less than 12 hours, the relative risk of ARTR was 1.66 (95% confidence interval, 1.01-2.73) in recipients with CIT of 24 hours or longer. Additionally, older age was associated with a decreased risk of ARTR. Compared with recipients aged 18 to 29 years, the relative risk of ARTR was 0.50 (95% confidence interval, 0.45-0.57) in recipients 60 years or older. Longer CIT was also associated with increased risk of death-censored graft loss. Compared with recipients with CIT less than 12 hours, the hazard ratio of death-censored graft loss was 1.22 (95% confidence interval, 1.14-1.30) in recipients with CIT of 24 hours or longer. CONCLUSIONS Prolonged CIT is associated with an increased risk of ARTR and death-censored graft loss. Older age was associated with a lower risk of ARTR.

Abstract
BACKGROUND The management of a deceased donor in the intensive care unit before organ transplantation is important for the outcome of the recipient. Herein, we analyze the pre-transplant resuscitation factors managed before procurement that could influence graft function immediately after deceased-donor kidney transplantation (DDKT). METHODS A total of 271 DDKTs performed at Seoul St. Mary's Hospital, Korea, from January 2009 to March 2016 were reviewed. We divided the patients into a delayed graft function (DGF) group and a non-DGF group, and compared postoperative outcomes between the 2 groups. We also analyzed the predisposing factors of DGF using multivariate analysis. RESULTS A total of 36 cases developed DGF while 235 patients did not, and the demographic characteristics of the recipients in the two groups had no significant difference. Of the pre-transplant resuscitation factors, preoperative polyuria, the maximal levels of serum sodium and BUN, and transfer times were significantly higher in the DGF group (P < .001). In a multivariable analysis, preoperative polyuria (odds ratio 4.835, P = .036), elevated preoperative level of sodium (odds ratio 1.227, P = .001), and extended transfer times (odds ratio 1.001, P < .001) were the independent risk factors of the donor in pre-transplant resuscitation management associated with DGF. CONCLUSIONS Polyuria, high levels of sodium before procurement, and prolonged transfer times are independent risk factors for DGF after a DDKT. Active intervention and early implementation of the intensivist can help in managing these factors effectively and thus ultimately improve graft function.

Abstract
Purpose We investigated the clinical outcomes of deceased donor kidney transplantation (KT) using kidneys with terminal acute kidney injury (AKI). Methods Between February 2000 and December 2013, we performed 202 deceased donor renal transplants from 159 brain dead donors. According to the expanded criteria donor (ECD) and AKI network criteria, we divided 202 recipients into 4 groups: Group I: Non-AKI & standard criteria donor (SCD) (n = 97); group II: Non-AKI & ECD (n = 15); group III: AKI & SCD (n = 52); and group IV: AKI & ECD (n = 38). Results The incidence of delayed graft function (DFG) was significantly higher in patients with AKI than it was in the non-AKI group (P = 0.008). There were no significant differences among the 4 groups in graft survival (P = 0.074) or patient survival (P = 0.090). However, the long-term allograft survival rate was significantly lower in group IV than it was in other groups (P = 0.024). Conclusion Allografts from deceased donors with terminal AKI had a higher incidence of DGF than did those from donors without AKI. However, there is no significant difference in graft and patient survival rates among the groups. So, the utilization of renal grafts from ECDs with terminal AKI is a feasible approach to address the critical organ shortage.

Abstract
OBJECTIVES Our objective was to evaluate the effect of kidney graft weight-to-recipient body weight ratio as a nonimmune factor that may affect long-term graft function. MATERIALS AND METHODS We retrospectively collected data from 2531 living donor kidney transplant procedures performed between 1994 and 2010 at Shahid Labbafinejad Medical Center; 635 patients were included in this study. Each kidney was weighed after cold wash. The kidney weight-to-recipient body weight ratio was calculated. As an indicator of graft function, we used the Modification of Diet in Renal Disease Study Group equation to estimate glomerular filtration rate. For statistical analyses, we used simple linear regression analysis and the mixed model test using SPSS version 17.0 software (SPSS, Chicago, IL, USA). RESULTS Mean age of recipients and median follow-up duration were 37.5 years (range, 6-77 y) and 36 months (range, 25-84 mo). Long-term graft function showed a positive correlation with kidney graft-to-recipient body weight ratio but not with the graft weight alone. The magnitude of this correlation was higher early after surgery (day 7) and decreased with long-term follow-up but was still statistically significant (P < .001). CONCLUSIONS From our results, we conclude that kidney graft-to-recipient body weight ratio is correlated with the kidney graft function; graft size matching may be considered for kidney donor selection.
