The role of donor hypertension and angiotensin II in the occurrence of early pancreas allograft thrombosis.

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.

Improving equity in kidney transplant allocation policies through a novel genetic metric: The Matched Donor Potential.

The demand for donors' kidneys continues to increase amid a shortage of available donors. Managing policies to thoughtfully allocate this scarce resource is a complex process. Although human leukocyte antigen (HLA) matching has been shown to prolong graft survival, its relative contribution to allocation schemes is empirically compromised owing to competing priorities.

Restriction of interleukin-6 alters endothelial cell immunogenicity in an allogenic environment.

The microvascular endothelium of the renal transplant is the first site of graft interaction with the host immune system and is often injured in chronic Antibody Mediated Rejection (AMR). Microvascular inflammation is an independent determinant of AMR and heightens endothelial expression of HLA molecules thereby increasing the possibility of Donor Specific Antibody (DSA) binding. Endothelial cells produce IL-6 in the steady-state and this is increased by inflammation or by HLA-DR antibody binding in an allogeneic setting.

[Medication adherence in renal transplantation: Evaluation, predictive factors and impact on humoral alloreactivity].

Objectives: The aims of this study were to assess medication adherence to immunosuppressive treatment in kidney transplanted patients, to identify predictive factors of medication non-adherence and to analyse its impact on the development of Donor Specific Antibodies (DSA) de novo, biomarkers of rejection in transplant recipients.

Methods: A cross-sectional single-centre study was conducted to assess medication adherence to immunosuppressive treatment with the BAASIS (Basel Assessment of Adherence Scale for Immunosuppressives) self-report questionnaire. Univariate and multivariate analyses were performed to determine non-adherence predictive factors and its role in the development of DSA de novo.
