Long-term results of autologous scaffold-free tissue-engineered vascular graft for hemodialysis access.

Background: The growing size of the end stage renal disease (ESRD) population highlights the need for effective dialysis access. Exhausted native vascular access options have led to increased use of catheters and prosthetic shunts, which are both associated with high risks of access failure and infection. Emerging alternatives include tissue-engineered vascular grafts (TEVG).

Beneficial Effect of Successful Simultaneous Pancreas-Kidney Transplantation on Plasma Profile of Metalloproteinases in Type 1 Diabetes Mellitus Patients.

It is not fully elucidated whether the restoring of normal glucose metabolism after successful simultaneous pancreas-kidney transplantation (SPK) improves vascular wall morphology and function in type 1 diabetic (T1D) patients. Therefore, we compared arterial stiffness, assessed by pulse wave velocity (PWV), carotid intima-media thickness (IMT), and biomarkers of arterial wall calcification in T1D patients after SPK or kidney transplantation alone (KTA). In 39 SPK and 39 KTA adult patients of similar age, PWV, IMT, circulating matrix metalloproteinases (MMPs) and calcification biomarkers were assessed at median 83 months post transplantation.

Early graft function and intrarenal resistant index after kidney transplantation using Biolasol-A new solid organ preservation fluid.

Biolasol is a newly developed preserving solution for cold organ storage prior to transplantation. To date, only animal model experiments results are available. The aim of this single-center analysis was to summarize the clinical experience concerning the early post-transplant course of kidney grafts preserved with Biolasol in comparison with other preservation solutions.

Metabolic acidosis in kidney transplant recipients.

Introduction Metabolic acidosis (MA) may accelerate the progression of chronic kidney disease (CKD) and is an important risk factor for increased mortality in CKD patients. The clinical value of MA in kidney transplant (KTx) recipients has not been extensively studied so far. Objectives The aim of this clinical single‑‑center case‑‑control study was to assess the prevalence of MA in KTx recipients in comparison with CKD patients and to identify pathogenic factors for MA in KTx recipients.

Comparison of Vascular Endothelial Growth Factor Concentration in Porcine Kidneys Removed From Living Donors After Cardiac and Brain Death.

The aim of this paper was to describe the differences in vascular endothelial growth factor (VEGF) concentration in porcine kidneys removed from living donors (group I), donors after prior induction of brain death by brain herniation (group II), and donors after cardiopulmonary arrest (group III). The groups consisted of 6 animals which underwent dual renal removal procedures; kidneys were rinsed, stored for 24 hours at 4°C and rinsed again. Renal specimens (4g) were collected before and after perfusion (time 0 and 1), after 12 hours (time 2), and after reperfusion (time 3).
