血小板减少是早期识别细菌性败血症的一项敏感指标。近发现败血症患者血清中血小板相关 IgG(platelet-associated IgG,PAIgG)和循环抗血小板抗体增加。因此,人们开始重视血小板破坏的免疫过程。本文旨在探讨血小板减少的败血症患者,其循环免疫复合物(immune complexes,ICs)和 PAIgG值等免疫学变化。 Thrombocytopenia is a sensitive indicator of early identification of bacterial sepsis. Serum platelet-associated IgG (PAIgG) and circulating anti-platelet antibodies have recently been found to be increased in sepsis patients. Therefore, people began to value the immune process of platelet destruction. This article aims to investigate the thrombocytopenia patients with thrombocytopenia immune complexes (immune complexes, ICs) and PAIgG values ​​and other immunological changes.
