Existing approaches for infection risk stratification in kidney transplant recipients are suboptimal. Here, we aimed to develop and validate a weighted score integrating non-pathogen-specific immune parameters and clinical variables to predict the occurrence of post-transplant infectious complications. To this end, we retrospectively analyzed a single-center derivation cohort of 410 patients undergoing kidney transplantation in 2008-2013 in Madrid.

Background: Graft thrombosis is a devastating complication after renal transplantation. We recently described the association of anti-beta-2-glycoprotein-I (IgA-ab2GP1) antibodies with early graft loss mainly caused by thrombosis in a monocenter study.

Methods: Multicenter prospective observational cohort study.

Introduction: Secondary hyperparathyroidism (SHPT) and vitamin D deficiency are common at kidney transplantation and are associated with some early and late complications. This study was designed to evaluate whether paricalcitol was more effective than nutritional vitamin D for controlling SHPT in kidney allograft recipients.

Methods: This was a 6-month, investigator-initiated, multicenter, open-label, randomized clinical trial.

No clear consensus has been reached regarding the optimal time to remove the peritoneal dialysis catheter (PDC) after kidney transplantation (KT). This retrospective observational study, conducted in a single peritoneal dialysis (PD) unit including all PD patients who received a KT between 1995 - 2015, was undertaken to evaluate the clinical outcomes and potential complications associated with a PDC left in place after KT. Of the 132 PD patients who received a KT, 20 were excluded from the study.

Aortobifemoral bypass (ABFB) thrombosis is not uncommon, and when the artery of a renal graft is implanted on a bypass the risk of graft loss is high. We report the case of a 48-year-old woman with a previous history of ABFB under antiplatelet therapy and a kidney allograft implanted on the vascular prosthesis, who presented with acute limb ischemia and severe renal impairment. Imaging techniques revealed a complete thrombosis of the proximal left arm of the ABFB.
