Abstract

Background: About 10-20% of pancreas allografts are still lost in the early postoperative period despite the identification of numerous detrimental risk factors that correlate with graft thrombosis. Methods: We conducted a multicenter study including 899 pancreas transplant recipients between 2000 and 2018. Early pancreas failure due to complete thrombosis, long-term pancreas, kidney and patient survivals were analyzed and adjusted to donor, recipient and perioperative variables using a multivariate cause-specific Cox model stratified to transplant centers. Results: Pancreas from donors with history of hypertension (6.7%), as well as with high body mass index (BMI), were independently associated with an increased risk of pancreas failure within the first 30 post-operative days (respectively, HR= 2.57, 95% CI from 1.35 to 4.89 and HR= 1.11, 95% CI from 1.04 to 1.19). Interaction term between hypertension and BMI was negative. Donor hypertension also impacted long-term pancreas survival (HR= 1.88, 95% CI from 1.13 to 3.12). However, when pancreas survival was calculated after the postoperative day 30, donor hypertension was no longer a significant risk factor (HR= 1.22, 95% CI from 0.47 to 3.15). A lower pancreas survival was observed in patients receiving a pancreas from a hypertensive donor without RAAS (Renin Angiotensin Aldosterone System) blockers compared to others (50% vs 14%, p < 0.001). Pancreas survival was similar among non-hypertensive donors and hypertensive ones under RAAS blockers. Conclusion: Donor hypertension was a significant and independent risk factor of pancreas failure. The well-known pathogenic role of renin-angiotensin-aldosterone system seems to be involved in the genesis of this immediate graft failure. [ABSTRACT FROM AUTHOR]

Abstract

Main problem The number of kidney transplant candidates with prosthetic heart valves (PHVs) is increasing. Yet, outcomes of kidney transplantation in these patients are still unclear. This is the first report of post-transplant outcomes in patients with PHVs at time of kidney transplantation. Methods We conducted a matched cohort study among recipients from the multicentric and prospective DIVAT cohort to compare outcomes in patients with left-sided PHVs at time of transplantation and a group of recipients without PHV matched according to age, dialysis time, initial disease, pre-transplant DSA, diabetes and cardiovascular events. Results Of 23018 patients, 92 patients with PHVs were included and compared to 276 patients without PHV. Delayed graft function and post-operative bleeding occurred more frequently in patients with PHVs. Kidney graft survival was similar between groups. 5-year overall survival was 68.5 % in patients with PHV versus 87.9 % in patients without PHV (HR, 2.72[1.57-4.70], p=0.0004). Deaths from infection, endocarditis and bleeding were more frequent in patients with PHV. Mechanical valves, but not bioprosthetic valves, were independent risk factors for mortality (HR, 2.89[1.68-4.97], p=0.0001). Conclusions Patients with PHV have high mortality rates after kidney transplantation. These data suggest that mechanical valves, but not biological valves, increase risks of post-transplant mortality.

Abstract

Acute kidney injury (AKI) caused by hantavirus infections is rare but should be suspected in any patient presenting with flu-like symptoms, signs of haemolytic–uraemic syndrome or presence of anti-glomerular basement membrane (anti-GBM) antibodies. We report the first case of Dobrava–Belgrade virus in France imported from southeastern Europe. The characteristic macroscopic appearance of the fresh renal biopsy specimen, displaying a haemorrhagic appearance of the medulla, suggested hantavirus infection. AKI caused by hantavirus infections remains a diagnostic challenge, especially outside endemic areas. [ABSTRACT FROM AUTHOR]

Abstract

Background: Binding of donor-specific antibodies (DSAs) to kidney allograft endothelial cells that does not activate the classic complement cascade can trigger the recruitment of innate immune effectors, including NK cells. Activated NK cells contribute to microvascular inflammation leading to chronic antibody-mediated rejection (AMR). Recipient NK cells can also trigger antibody-independent microvascular inflammation by sensing the absence of self HLA class I molecules ("missing self") on allograft endothelial cells. This translational study investigated whether the condition of missing self amplifies DSA-dependent NK cell activation to worsen chronic AMR., Methods and Results: Among 1682 kidney transplant recipients who underwent an allograft biopsy at Lyon University Hospital between 2004 and 2017, 135 fulfilled the diagnostic criteria for AMR and were enrolled in the study. Patients with complement-fixing DSAs identified by a positive C3d binding assay ( n =73, 54%) had a higher risk of transplant failure ( P =0.002). Among the remaining patients with complement-independent chronic AMR ( n =62, 46%), those in whom missing self was identified through donor and recipient genotyping exhibited worse allograft survival ( P =0.02). In multivariable analysis, only proteinuria (HR: 7.24; P =0.01) and the presence of missing self (HR: 3.57; P =0.04) were independent predictors for transplant failure following diagnosis of chronic AMR. Cocultures of human NK cells and endothelial cells confirmed that addition of missing self to DSA-induced NK cell activation increased endothelial damage., Conclusions: The assessment of missing self at the time of diagnosis of chronic AMR identifies patients at higher risk for kidney transplant failure., (Copyright © 2021 by the American Society of Nephrology.)
