Abstract
BACKGROUND The Naples prognostic score is a comprehensive measure of patients' inflammation and nutritional status, consisting of serum albumin, total cholesterol, neutrophil/lymphocyte ratio (NLR), and lymphocyte/monocyte ratio (LMR). We compared the Naples prognostic scores of kidney transplant patients with a creatinine reduction ratio of less than 30% vs those with greater than 30%. MATERIAL AND METHODS We conducted a retrospective study on 93 patients who received kidney transplants at our hospital from January 2020 to January 2023. Naples prognostic scores were used to calculate the preoperative condition of transplant recipients. The patients were divided into 2 groups based on their creatinine reduction ratio on the second day after surgery. Group A consisted of patients with a ratio above 30%, while group B consisted of those with a ratio below 30%. RESULTS Our analysis revealed that the total cholesterol and albumin values of groups A and B showed no substantial difference. Group B had clearly more patients with Naples prognostic score 3-4 compared to the other group (P=0.032). Multivariate analysis determined that patients with Naples prognostic score 3-4 had a 3.151-fold higher likelihood of experiencing creatinine reduction below 30% (95% CI 1.209-8.215, P value 0.019). CONCLUSIONS The preoperative inflammatory and nutritional status of patients may have an impact on the functioning of grafts during the postoperative period. A high Naples prognostic score may be linked with a decrease in creatinine reduction ratio in post-transplant kidneys, which could lead to graft dysfunction.

Abstract
BACKGROUND Noninvasive alternatives to biopsy for assessment of interstitial fibrosis and tubular atrophy (IFTA), the major determinant of kidney transplant failure, remain profoundly limited. Elastography is a noninvasive technique that propagates shear waves across tissues to measure their stiffness. We aimed to test utility of elastography for early detection of IFTA in pediatric kidney allografts. METHODS We compared ultrasound (USE) and MR elastography (MRE) stiffness measurements, performed on pediatric transplant recipients referred for clinically indicated biopsies, and healthy controls. RESULTS Ten transplant recipients (median age 16 years) and eight controls (median age 16.5 years) were enrolled. Three transplant recipients had "stable" allografts and seven had Banff Grade 1 IFTA. Median time from transplantation to biopsy was 12 months. Mean estimated glomerular filtration rate was 61.5 mL/min/1.73m2 by creatinine-cystatin-C CKiD equation at time of biopsy. Mean stiffness, calculated through one-way ANOVA, was higher for IFTA allografts (23.4 kPa USE/5.6 kPa MRE) than stable allografts (13.7 kPa USE/4.4 kPa MRE) and controls (9.1 kPa USE/3.6 kPa MRE). Pearson's coefficient between USE and MRE stiffness values was strong (r = .97). AUC for fibrosis prediction in transplanted kidneys was high for both modalities (0.91 USE and 0.89 MRE), although statistically nonsignificant (p > .05). Stiffness cut-off values for USE and MRE were 13.8 kPa and 4.6 kPa, respectively. Both values yielded a sensitivity of 100% but USE specificity (72%) was slightly higher than MRE (67%). CONCLUSION Elastography shows potential for detection of low-grade IFTA in allografts although a larger sample is imperative for clinical validation.

Transpl Int 2023; 36:11381.

Abstract
Antibody mediated rejection (ABMR) is the leading cause of immune-related allograft failure following kidney transplantation. Chronic active ABMR (CABMR) typically occurs after one-year post-transplant and is the most common cause of late allograft failure. This study was designed to assess common practices in Europe for post-transplant surveillance 1 year after kidney transplant, as well as the diagnosis and management of CABMR. A 15-minute online survey with 58 multiple choice or open-ended questions was completed by EU transplant nephrologists, transplant surgeons and nephrologists. Survey topics included patient caseloads, post-transplant routine screening and treatment of CABMR. The results indicated that observing clinical measures of graft function form the cornerstone of post-transplant surveillance. This may be suboptimal, leading to late diagnoses and untreatable disease. Indeed, less than half of patients who develop CABMR receive treatment beyond optimization of immune suppression. This is attributable to not only late diagnoses, but also a lack of proven efficacious therapies. Intravenous Immunoglobulin (IVIG), steroid pulse and apheresis are prescribed by the majority to treat CABMR. While biologics can feature as part of treatment, there is no single agent that is being used by more than half of physicians.

Impact on grafted kidney function of rocuronium-sugammadex vs cisatracurium-neostigmine strategy for neuromuscular block management. An Italian single-center, 2014-2017 retrospective cohort case-control study. Perioper Med (Lond) 2022; 11:3. [PMID: 35022076 PMCID: PMC8756660 DOI: 10.1186/s13741-021-00231-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Accepted: 11/18/2021] [Indexed: 11/16/2022] Open
Abstract
Background The impact of sugammadex in patients with end-stage renal disease undergoing kidney transplantation is still far from being defined. The aim of the study is to compare sugammadex to neostigmine for reversal of rocuronium- and cisatracurium-induced neuromuscular block (NMB), respectively, in patients undergoing kidney transplantation. Methods A single-center, 2014-2017 retrospective cohort case-control study was performed. A total of 350 patients undergoing kidney transplantation, equally divided between a sugammadex group (175 patients) and a neostigmine group (175 patients), were considered. Postoperative kidney function, evaluated by monitoring of serum creatinine and urea and estimated glomerular filtration rate (eGFR), was the endpoint. Other endpoints were anesthetic and surgical times, post-anesthesia care unit length of stay, postoperative intensive care unit admission, and recurrent NMB or complications. Results No significant differences in patient or, with the exception of drugs involved in NMB management, anesthetic, and surgical characteristics, were observed between the two groups. Serum creatinine (median [interquartile range]: 596.0 [478.0-749.0] vs 639.0 [527.7-870.0] μmol/L, p = 0.0128) and serum urea (14.9 [10.8-21.6] vs 17.1 [13.1-22.0] mmol/L, p = 0.0486) were lower, while eGFR (8.0 [6.0-11.0] vs 8.0 [6.0-10.0], p = 0.0473) was higher in the sugammadex group than in the neostigmine group after surgery. The sugammadex group showed significantly lower incidence of postoperative severe hypoxemia (0.6% vs 6.3%, p = 0.006), shorter PACU stay (70 [60-90] min vs 90 [60-105] min, p < 0.001), and reduced ICU admissions (0.6% vs 8.0%, p = 0.001). Conclusions Compared to cisatracurium-neostigmine, the rocuronium-sugammadex strategy for reversal of NMB showed a better recovery profile in patients undergoing kidney transplantation.

Multivariate Longitudinal Assessment of Kidney Function Outcomes on Graft Survival after Kidney Transplantation Using Multivariate Joint Modeling Approach: A Retrospective Cohort Study. IRANIAN JOURNAL OF MEDICAL SCIENCES 2021; 46:364-372.

Abstract
Background The performance of a transplanted kidney is evaluated by monitoring variations in the value of the most important markers. These markers are measured longitudinally, and their variation is influenced by other factors. The simultaneous use of these markers increases the predictive power of the analytical model. This study aimed to determine the simultaneous longitudinal effect of serum creatinine and blood urea nitrogen (BUN) markers, and other risk factors on allograft survival after kidney transplantation. Methods In a retrospective cohort study, the medical records of 731 renal transplant patients, dated July 2000 to December 2013, from various transplant centers in Mashhad (Iran) were examined. Univariate and multivariate joint models of longitudinal and survival data were used, and the results from both models were compared. The R package joineRML was used to implement joint models. P values <0.05 were considered statistically significant. Results Results of the multivariate model showed that allograft rejection occurred more frequently in patients with elevated BUN levels (HR=1.68, 95% CI: 1.24-2.27). In contrast, despite a positive correlation between serum creatinine and allograft rejection (HR=1.49, 95% CI: 0.99-2.22), this relationship was not statistically significant. Conclusion Results of the multivariate model showed that longitudinal measurements of BUN marker play a more important role in the investigation of the allograft rejection.

Abstract
Background Renal transplant has emerged as a preferred treatment modality in cases of end-stage renal disease; however, a small percentage of cases suffer from graft dysfunction. Aim To evaluate the renal transplant biopsies and analyze the various causes of graft dysfunction. Materials and Methods 163 renal transplant biopsies, reported between 2014 and 2019 and who fulfilled the inclusion criteria, were evaluated with respect to demographics, clinical, histological, and immunohistochemical features. Results Of 163 patients, 26 (16%) were females and 137 (84%) were males with a mean age of 34 ± 7 years. 53 (32.5%) cases were of rejection (ABMR and TCMR), 1 (0.6%) was borderline, 15 were of IFTA, and rest of 94 cases (57.7%) belonged to the others category. SCr (serum creatinine) in cases of rejection was 3.85 ± 0.55 mg/dl. Causes of early graft dysfunction included active ABMR (7.1 ± 4.7 months), acute TCMR (5.5 months), and acute tubular necrosis (after 6 ± 2.2 months of transplant) while the causes of late rejection were CNIT and IFTA (34 ± 4.7 and 35 ± 7.8 months, respectively). Conclusion Renal graft dysfunction still remains a concerning area for both clinicians and patients. Biopsy remains the gold standard for diagnosing the exact cause of graft dysfunction and in planning further management.

Effects of Sugammadex Plus Rocuronium vs Neostigmine Plus Cisatracurium During Renal Transplantation on Graft Function: A Retrospective, Case-Control Study. Transplant Proc 2020; 53:818-824. [PMID: 33069485 DOI: 10.1016/j.transproceed.2020.09.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Revised: 08/27/2020] [Accepted: 09/20/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND Rocuronium can be used in patients with severe renal failure (creatinine clearance <30 mL/min), but the duration of muscle relaxation is longer and results in an increased risk of postoperative residual neuromuscular block. Rocuronium can be antagonized by sugammadex, but the elimination of the complex they make (rocuronium-sugammadex complex) varies according to the renal function. Two case reports/series have reported the use of rocuronium-sugammadex complex during renal transplantation. A recently published retrospective study showed no differences in postoperative creatinine levels in patients receiving kidney transplantation. This retrospective case-control study aims to investigate the effects of rocuronium-sugammadex, used during renal transplantation, on transplanted kidney function. METHODS We analyzed 113 medical records of patients undergoing kidney transplantation from January 2015 to December 2018. Forty-seven medical records were excluded because they did not report the administration of one of the following drugs during the transplantation: rocuronium, sugammadex, cisatracurium, neostigmine. The demographics of patients and donors were collected along with the following data: blood urea and creatinine, serum and urinary electrolytes, and diuresis. Marginal, single, or double kidney transplantations; Karpinski scores; and histologic evaluations of transplanted kidney were collected. RESULTS We included data from 66 medical reports from January 2015 to December 2018. Blood creatinine levels at 6, 12, and 24 hours were significantly lower in the rocuronium + sugammadex group than in the cisatracurium + neostigmine group (creatinine 6 hours P = .05, creatinine 12 hours P = .038, creatinine 24 hours P = .049). Blood urea levels for 24 hours after transplantation were significantly lower in the rocuronium + sugammadex group than in the cisatracurium + neostigmine group (urea 0 hours P = .025, urea 6 hours P = .011, urea 12 hours P = .03, urea 24 hours P = .011). We found no statistically significant differences in blood sodium, blood potassium, blood calcium, diuresis, urinary sodium, or urinary potassium levels before and after transplantation. CONCLUSIONS In this retrospective case-control study, the use of rocuronium and sugammadex during renal transplant surgery did not affect relevant kidney recovery outcomes in the first week after transplantation.
