Detection of antiplatelet antibody activity in patients with renal cortical necrosis

Abstract

Detection of antiplatelet antibody activity in patients with renal cortical necrosis. Sera were collected from 14 patients with renal cortical necrosis (RCN) and tested for lymphocytotoxic antibody, antiglomerular basement membrane antibody and antiplatelet antibody. Three of 11 patients (27%) had at least one lymphocytotoxic antibody, none had anti-GBM antibody, while 11 of 14 patients (79%) were found to have a serum factor which released platelet factor III. Antiplatelet antibody activity was found in 33% of sera from 23 patients with non-RCN renal failure. It was of interest to note that the higher incidence of antiplatelet antibody activity in RCN was accompanied by a high incidence of early allograft faulure in 31 such patients receiving renal transplantation.Détection d'une activité anticorps anti-plaquettes chez des malades atteints de nécrose corticale du rein. Le sérum de 14 malades atteints de nécrose corticale rénale (RCN) a été étudié pour rechercher des anticrops lymphocytotoxiques, anti-membrane basale glomérulaire (GBM) et antiplaquettes. Trois malades sur 11 (27%) avaient au moins un anticorps lymphocytotoxique, aucun n'avait d'anticorps anti-GBM et 11 malades sur 14 (74%) avaient un facteur sérique qui libérait le facteur plaquettaire III. Une activité anticorps anti-plaquettes a été trouvée dans 33% des sérums de 23 malades atteints d'insuffisance rénale sans RCN. Il est intéressant de remarquer que la fréquence élevée d'activité anticorps anti-plaquettes dans RCN est concomittante d'une fréquence élevée de rejets précoces de greffes chez 31 de ces malades soumis à une transplantation rénale
