Activation of final complement components after kidney transplantation as a marker of delayed graft function severity.

Clin Kidney J 2021 Apr 10;14(4):1190-1196. Epub 2020 Oct 10.

Department of Nephrology, Hospital del Mar, Barcelona, Catalunya, Spain.

Background: Ischaemia-reperfusion (I/R) damage is a relevant cause of delayed graft function (DGF). Complement activation is involved in experimental I/R injury, but few data are available from kidney transplant (KT) patients. We studied the dynamics of membrane attack complex (C5b-9) as a soluble fraction (SC5b-9) and the histological deposit pattern of C3b, complement Factor H (FH) and C5b-9 in DGF patients. Read More

Recipient pre-existing chronic hypotension is associated with delayed graft function and inferior graft survival in kidney transplantation from elderly donors.

PLoS One 2021 5;16(4):e0249552. Epub 2021 Apr 5.

Renal Transplant Center "A. Vercellone," Nephrology, Dialysis, and Renal Transplant Division, Department of Medical Sciences, "AOU Città Della Salute e Della Scienza di Torino" University Hospital, University of Turin, Turin, Italy.

Background: Pre-existing chronic hypotension affects a percentage of kidney transplanted patients (KTs). Although a relationship with delayed graft function (DGF) has been hypothesized, available data are still scarce and inconclusive.

Methods: A monocentric retrospective observational study was performed on 1127 consecutive KTs from brain death donors over 11 years (2003-2013), classified according to their pre-transplant Mean Blood Pressure (MBP) as hypotensive (MBP < 80 mmHg) or normal-hypertensive (MBP ≥ 80 mmHg, with or without effective antihypertensive therapy).

Role of C5aR1 and C5L2 Receptors in Ischemia-Reperfusion Injury.

J Clin Med 2021 Mar 2;10(5). Epub 2021 Mar 2.

Department of Nephrology, Parc de Salut Mar, 08003 Barcelona, Spain.

The role of C5a receptors (C5aR1 and C5L2) in renal ischemia-reperfusion injury (IRI) is uncertain. We generated an in vitro model of hypoxia/reoxygenation with human proximal tubule epithelial cells to mimic some IRI events. C5aR1, membrane attack complex (MAC) and factor H (FH) deposits were evaluated with immunofluorescence. Read More

The Relationship Between Pre-Transplant Serum Phosphorus Before Kidney Transplantation with Early Graft Dysfunction.

Iran J Kidney Dis 2021 Mar;1(2):148-154

1Kidney Transplantation Complications Research Center, Mashhad University of Medical Sciences, Mashhad, Iran.

Introduction: Pre-transplant serum phosphorus level is shown to be associated with some transplant outcomes in patients with chronic kidney disease. However, its association with Delayed graft function (DGF) has an aura of ambiguity. DGF means either the patient needs dialysis during the first week after transplantation or the creatinine level is ≥ 3. Read More

Effect of delayed graft function on longer-term outcomes after kidney transplantation from donation after circulatory death donors in the UK: a national cohort study.

Am J Transplant 2021 Mar 23. Epub 2021 Mar 23.

Department of Nephrology and Transplantation, NHS Foundation Trust, Guy's and St Thomas, London, UK.

Kidneys from donation after circulatory death (DCD) donors are utilized variably worldwide, in part due to high rates of delayed graft function (DGF) and putative associations with adverse longer-term outcomes. We aimed to determine whether the presence of DGF, and its duration, were associated with poor longer-term outcomes after kidney transplantation from DCD donors. Using the UK transplant registry, we identified 4714 kidney-only transplants from controlled DCD donors to adult recipients between 2006-2016; 2832 recipients (60·1%) had immediate graft function and 1882 (39.

Delayed graft function and rejection are risk factors for cytomegalovirus breakthrough infection in kidney transplant recipients.

Pharmacol Res 2021 Mar 17;167:105565. Epub 2021 Mar 17.

Department of Clinical Pharmacy and Toxicology, Leiden University Medical Center, Postbus 9600, 2300 RC Leiden, The Netherlands.

Breakthrough cytomegalovirus (CMV) disease during valganciclovir prophylaxis is rare but may cause significant morbidity and even mortality. In order to identify patients at increased risk the incidence of CMV disease was studied in a large population of renal transplant recipients who underwent a kidney transplantation in the Radboud University Medical Center between 2004 and 2015 (n = 1300). CMV disease occurred in 31/1300 patients. Read More

The predictive value of urinary kidney injury molecular-1 for long-term graft function in kidney transplant patients: a prospective study.

Ann Transl Med 2021 Feb;9(3):244

Department of Nephrology, Molecular Cell Laboratory for Kidney Disease, Renji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.

Background: Monitoring allograft function during the early stages is crucial, and therefore requires biomarkers more sensitive than serum creatinine (Scr). Kidney injury molecular-1 (KIM-1) is a potent biomarker; however, disparities exist in the literature concerning its predictive value in allograft function. Therefore, this study aimed to evaluate its predictive value for the long-term prognosis of kidney transplantation patients. Read More

GlaxoSmithKline, Philadelphia, Pennsylvania, United States of America.

Introduction: Delayed graft function (DGF) following renal transplantation is a manifestation of acute kidney injury (AKI) leading to poor long-term outcome.

Phase 3 trial Design of the Hepatocyte Growth Factor Mimetic ANG-3777 in Renal Transplant Recipients With Delayed Graft Function.

Kidney Int Rep 2021 Feb 13;6(2):296-303. Epub 2020 Nov 13.

Angion Biomedica, Uniondale, NY.

Introduction: One-third of kidney transplantation patients experience acute kidney injury (AKI) resulting in delayed graft function (DGF), associated with increased risk of graft failure and mortality. Preclinical and phase 2 data indicate that treatment with ANG-3777 (formerly BB3), a hepatocyte growth factor (HGF) mimetic, may improve long-term kidney function and reduce health care resource use and cost, but these data require validation in a phase 3 randomized controlled trial.

Methods: The Graft Improvement Following Transplant (GIFT) trial is a multicenter, double-blind randomized controlled trial, designed to determine the efficacy and safety of ANG-3777 in renal transplantation patients showing signs of DGF. Read More

Protection From the Second Warm Ischemic Injury in Kidney Transplantation Using an Ex Vivo Porcine Model and Thermally Insulating Jackets.

Transplant Proc 2021 Mar 11;53(2):750-754. Epub 2021 Feb 11.

Sydney Medical School, University of Sydney, Sydney, Australia; Department of Surgery, Westmead Hospital, Westmead, Australia.

Background: Kidney transplantation is the optimum treatment for kidney failure in carefully selected patients. Technical surgical complications and second warm ischemic time (SWIT) increase the risk of delayed graft function (DGF) and subsequent short- and long-term graft outcomes including the need for post-transplant dialysis and graft failure. Intraoperative organ thermal regulation could reduce SWIT, minimizing surgical complications due to time pressure, and limiting graft ischemia-reperfusion injury. Read More

Risk factors and outcomes for delayed kidney graft function in simultaneous heart and kidney transplant recipients: A UNOS/OPTN database analysis.

Am J Transplant 2021 Feb 10. Epub 2021 Feb 10.

Division of Nephrology, Department of Medicine, School of Medicine and Public Health, University of Wisconsin, Madison, Wisconsin.

There are no prior studies assessing the risk factors and outcomes for kidney delayed graft function (K-DGF) in simultaneous heart and kidney (SHK) transplant recipients. Using the OPTN/UNOS database, we sought to identify risk factors associated with the development of K-DGF in this unique population, as well as outcomes associated with K-DGF. A total of 1161 SHK transplanted between 1998 and 2018 were included in the analysis, of which 311 (27%) were in the K-DGF (+) group and 850 in the K-DGF (-) group. Read More
