Low-dose Arginine-vasopressin Supplementation on Post-transplant Acute Kidney Injury After Liver Transplantation (AVENIR Trial)

Официальное название

Effect of Low-dose Arginine-vasopressin Supplementation on Post-transplant Acute Kidney Injury After Liver Transplantation

Обзор

Liver transplantation (LT) is a high-risk surgery for hemodynamic instability and haemorrhagic shock with a high-risk of acute kidney injury (AKI). Indeed, the incidence of post-transplant AKI exceeds 50% in some series with 15% of patients requiring renal replacement therapy. Acute kidney injury after LT is a predisposing factor for chronic renal failure which is independently associated with higher morbidity and mortality. Arginine vasopressin (AVP), an essential stress hormone released in response to hypotension, binds to AVPR1a to promote vasoconstriction. Furthermore, it may have nephroprotective effects with a preferential vasoconstriction of the post-glomerular arteriole resulting in increased glomerular filtration The hypothesis of the present work is that low-dose arginine-vasopressin supplementation reduce posttransplant AKI in liver transplantation.

Подробное описание

Prospective, national multicenter, double-blinded, randomized , controlled superiority trial with two parallel arms : AVP vs Norepinephrine

The primary objective is to demonstrate that intraoperative low-dose supplementation of AVP induces a reduction in posttransplant AKI after liver transplantation

Investigational medicinal product: vasopressin will be administered by continuous infusion. AVP will be used to a final concentration of 0.12 U/ml. The vasopressor infusion will be titrated to maintain an MAP of at least 65 mmHg. The study-drug infusion will be started at 5 ml/h and increased by 2.5 ml/h to achieve a maximum target rate of 30 ml/h, so that AVP doses ranged from 0.01 to 0.06 U/min.

Comparator treatment : norepinephrine will be administered by continuous infusion. Norepinephrine will be used with final concentrations of 120 microg/ml. The vasopressor infusion will be titrated to maintain an MAP of at least 65 mmHg. The study-drug infusion will be started at 5 ml/h and increased by 2.5 ml/h to achieve a maximum target rate of 30 ml/h, so that NE doses ranged from10 to 60 microg/min.
