Abstract

Antiphospholipid syndrome (APS) is defined as an autoimmune and prothrombotic disorder in patients with the persistent presence of antiphospholipid antibodies (aPLs). In the classification criteria, aPL expresses lupus anticoagulant (LA) activity, which is detected by prolongation of coagulation assays. The LA detection algorithm is a sequential flow including screening tests, mixing tests, and confirmatory tests to differentiate between LA-positive and other anticoagulant abnormalities. Two types of assays are used, like dilute Russell’s viper venom time (dRVVT) and activated partial thromboplastin time (APTT) because no single test is sensitive to all LAs. The anticoagulant drugs prescribed for the prevention and treatment of thrombosis disorders can interfere with the assays, and it is important to know the effects of these drugs in the assays. Especially, new generation anticoagulant drugs, called direct oral anticoagulants (DOACs), affect the results. In this review, the following points are discussed: i) LA detection flow and data interpretation, ii) the principles of coagulation assays proposed and their characteristics, and iii) the effects of anticoagulant drugs in LA detection.

狼疮抗凝血剂和抗磷脂综合征诊断的实验室实践进展
抗磷脂综合征(APS)被定义为抗磷脂抗体(APS)持续存在的患者的自身免疫和血栓形成前疾病。在分类标准中,aPL表达狼疮抗凝血剂(LA)活性,通过延长凝血试验来检测。LA检测算法是一个连续的流程,包括筛选试验、混合试验和确认试验,以区分LA阳性和其他抗凝异常。使用两种类型的测定,如稀释罗素毒蛇毒液时间(dRVVT)和活化部分凝血活素时间(APTT),因为没有单一的测试是敏感的所有LAs。用于预防和治疗血栓障碍的抗凝药物会干扰检测,了解这些药物在检测中的作用是很重要的。特别是新一代抗凝药物,称为直接口服抗凝剂(DOACs),影响结果。本文就以下几点进行综述:1)LA检测流程和数据解释;2)提出的凝血试验原理及其特点;3)抗凝药物在LA检测中的作用。
