Relatively high levels of anti-HLA antibodies (measured by Luminex Single-Antigen bead assay) are required to mediate inhibition of lymphocyte proliferation induced by sera from alloimmunized renal patients.

Background: Rejection of transplanted organs is caused by alloimmune responses, primarily against HLA molecules. Anti-donor HLA antibodies are associated with antibody-mediated rejection (AMR) and poor graft outcome. Because of clinical interest in detecting these antibodies, new technologies have recently been introduced to increase the sensitivity of detection.

Predictive value of the Luminex single antigen panel for detecting flow cytometry cross-match positivity.

Anti-human leukocyte antigen (HLA) antibodies are a major cause of allograft loss. Solid-phase immunoassays, notably Luminex technology, have lately begun to replace traditional techniques for detecting these antibodies. This platform, however, carries some restrictions in the type of antibodies it detects.

Randomized clinical trial on acute effects of i.v. iron sucrose during haemodialysis.

Aim: Haemodialysis induces endothelial dysfunction by oxidation and inflammation. Intravenous iron administration during haemodialysis could worsen endothelial dysfunction. The aim of this study was to ascertain if iron produces endothelial dysfunction and the possible neutralizing effect of N-acetylcysteine when infused before iron.

Angiogenic and prothrombotic markers in extensive slow-flow vascular malformations: implications for antiangiogenic/antithrombotic strategies.

Background: Venous and combined malformations are slow-flow haemodynamically inactive lesions that are present at birth and worsen slowly with advancing age, showing no tendency towards involution. The pathogenesis of vascular anomalies has not been fully elucidated, but their formation and progression are closely related to angiogenesis. Localized intravascular coagulation associated with venous or combined malformations is characterized by low fibrinogen, high D-dimers, and normal platelet count.
