Between July 2001 and November 2003, 16 patients with a positive flow-cytometry crossmatch to their potential living donor for kidney transplant were treated with desensitization protocol based on plasmapheresis and low-dose IVIg starting 1 week before the scheduled transplant. Twelve patients (75%) converted to negative crossmatch and were successfully transplanted. Immunosuppression consisted of induction with thymoglobulin, tacrolimus, mycophenolate mofetil, and steroids. Plasmapheresis and IVIg were continued on alternate days for the first postoperative week. The 1-year patient and graft survival was 100%. The rate of acute rejection was 41% (16% cellular and 25% humoral). All of the rejection episodes resolved with treatment. Combination of plasmapheresis and IVIg allows successful conversion from positive to negative flow-cytometry crossmatch in 75% of cases; after conversion, kidney transplant can be carried out with a high rate of success.

Background: KEPs (kidney exchange programs) facilitate living donor kidney transplantations (LDKT) for patients with incompatible donors, who are typically higher risk than non-KEP patients because of higher sensitization and longer dialysis vintage. We conducted a comparative analysis of graft outcomes and risk factors for both KEP and non-KEP living donor kidney transplants.

Methods: All LDKTs performed in the Netherlands between 2004-2021 were included.

Background: Chronic kidney disease (CKD) is a significant risk factor for cerebrovascular disease. However, there is limited research on how successful living donor kidney transplantation (LDKT) affects cerebral blood flow (CBF). This study aims to comprehensively investigate how LDKT influences CBF across various brain levels and regions.

Background: Multiple intraoperative hemodynamic parameters are associated with an increased risk of early allograft dysfunction (EAD) following living donor liver transplantation (LDLT); however, there is significant center-to-center variability in terms of which parameters are used. We sought to determine which intraoperative hemodynamic parameters are most predictive of EAD following LDLT.

Methods: This is a systematic review following PRISMA guidelines (PROSPERO ID: CRD42023409711).

Background: Parkinson's disease (PD) is a neurodegenerative disorder characterized by protein aggregates mostly consisting of misfolded alpha-synuclein (αSyn). Progressive degeneration of midbrain dopaminergic neurons (mDANs) and nigrostriatal projections results in severe motor symptoms. While the preferential loss of mDANs has not been fully understood yet, the cell type-specific vulnerability has been linked to a unique intracellular milieu, influenced by dopamine metabolism, high demand for mitochondrial activity, and increased level of oxidative stress (OS).

Background: Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic cause of end-stage kidney disease (ESKD) and occurs without racial predilection. In general, non-White ESKD patients have less access to transplantation, especially living donor transplantation. We examined long-term outcomes of ADPKD-ESKD patients by self-reported race, with attention to the trajectory of Estimated Post-Transplant Survival (EPTS) scores over time.
