Antiphospholipid antibodies and Mycoplasma pneumoniae infection

Anticardiolipin antibody levels were measured in 57 patients with Mycoplasma pneumoniae infection and 21 patients with other infections. Significantly more patients in the mycoplasma group had increased IgM and IgG anticardiolipin. Within the mycoplasma group significantly higher titres were found in patients with severe infection (assessed by need for hospital admission) and in patients with cold agglutinins. A tendency for particularly high titres to occur in patients with extra-pulmonary complications was identified.     

Antiphospholipid Antibody and Antiphospholipid Syndrome

Antiphospholipid antibodies （APA） APA is a big category for all kinds of negative charge phospholipid or lecithin - a protein complex autoantibodies or the same antibody, through its recognition of antigen （ target protein） different, and phospholipids or lecithin - protein complex combination of various rely on the interference Phospholipid clotting and anti-coagu- lation factor, and promote endothelial cells, platelets, complement activation and play a role. APA including lupus anticoagulant （ LA ） and anticardiolipin antibody （ACA）, In addition, there are anti-β2 glycoprotein-I （β2-GPI） antibody, anti- prothrombin （ a- PT） antibody, anti-lysophosphatidic acid antibody and anti-phosphatidylserine antibody, and so on. APA as the main target of phospholipid-binding protein, including β2-GPI, prothrombin, annexin, protein C （PC） and protein S （PS） , plasminogen, and so on.     

抗磷脂综合征

1 概述抗磷脂综合征(APS)是常见的获得性易栓症的原因之一, 是由两类抗磷脂抗体(APA)所致,为自身免疫性疾病。一类抗体作用于磷脂,另一类抗体作用于磷脂结合蛋白,通过干扰依赖磷脂的各种凝血与抗凝血因子的功能而导致血栓形成。狼疮性抗凝物(IA)和抗心磷脂抗体(aGP)都属于 APA、APA(?)     

抗磷脂血栓综合征

目的:了解抗磷脂抗体(APA)与抗磷脂血栓综合征(APL-T)相关性,进一步探讨APL-T血栓发生机制。方法:采用 ELISA检测ACA(IgG,M,A),PTT-LA检测LA,APTT /-APC检测APC-R。结果:20例患者符合 APL-T诊断。根据病因分类:14/100例SLE为继发性 APL-T;6/16例“原因不明”血栓与习惯性流产为原发性APL-T。根据抗体分类:12/20例LA阳性为狼疮抗凝因子血栓综合征(LA-T);12/20例ACA阳性为抗心磷脂抗体血栓综合征(ACA-T)。根据临床症状分类:7/20例静脉血栓为Ⅰ型,3/20例脑梗塞为Ⅱ型;1/20例静脉血栓合并脑梗塞,习惯性流产为Ⅳ型(混全型);9/20例习惯性流产为Ⅴ型APL-T。APL-T患者LA阳性率(12/20,60％)明显高于正常对照组(NC组0/20,0%)。患者ACA-IgG,M与NC组比较有显著性差异(P<0.05);APCR在APL-T患者中阳性率(14/20,70％)明显高于NC组(l/20,5％);LA阳性组中的APCR阳性率(10/11,90.9％)明显高于LA阴性组(l/11,9％),ACA阳性组的APCR阳性率(7/11,63.3％)与ACA阴性组(4/11,36.36％)比较有显著性差异。结论:APA与APCR密切相关,APL-T中血栓发生率与APA以及APCR存在明显相关性,说明APA对PC途径的抑制引起获得性APCR可能是APL-T血栓发生的重要原因,故可将APA作为血栓危险性增加的标志物。     

Antiphospholipid antibody-related Bell's palsy in young women

The present report describes three young women aged 25, 20 and 15 years who presented with Bell's palsy. Two of the patients had a past history of the disease, which responded to steroid treatment. All three patients were positive for antiphospholipid antibody (APLA). In addition, one of the patients tested positive for antinuclear antibodies; however, there was no clinical evidence of systemic lupus erythematosus. All three patients responded well to steroid therapy. We conclude that Bell's palsy may be one of the manifestations of APLA syndrome, and thus, APLA testing should be done in such cases.     

Antiphospholipid syndrome: an overview

ANTIPHOSPHOLIPID ANTIBODIES ARE A HETEROGENEOUS GROUP of autoantibodies that are detected by immunoassays and functional coagulation tests. The antigenic targets are negatively charged phospholipids and serum phospholipid-binding proteins. The latter antibodies are frequently associated with thrombosis, fetal loss and other clinical manifestations of the antiphospholipid syndrome. These antibodies are felt to be etiologically important in the syndrome, although the precise pathogenic mechanisms are still being determined. Proposed mechanisms include antibody-mediated interference with coagulation homeostasis, activation of platelets and endothelial cells and a T-cell immune response to serum phospholipid-binding proteins. The mainstay of therapy is anticoagulation, whereas immunosuppression is ineffective.     

抗磷脂抗体与恶性肿瘤相关易栓症

抗磷脂抗体（antiphospholipid antibody,aPL）是一组与各种带阴电荷磷脂抗原发生反应的多种抗体的总称,包括狼疮抗凝物（lupus anticoagulant,LA）、抗心磷脂抗体（anticardiolipin antibodies,aCL）、抗磷脂酸抗体以及抗磷脂酰丝氨酸抗体等.血液中高滴定度的aPL是抗磷脂综合征（antiphospholipid syndrome,APS）反复的动静脉血栓形成的极其关键的因素.正常健康人aPL的检出率大约为4.5％ ～9.4％.     

抗磷脂抗体与妊娠丢失

抗磷脂抗体与妊娠丢失有密切关系,其主要发病机制是胎盘血栓形成,时抗磷脂抗体异常的患者给予抗凝治疗及免疫抑制剂,配合中医疗法,可明显改善其妊娠结局.     

抗磷脂综合征的研究进展

抗磷脂综合征（antiphospholipid syndrome，APS）是一组以反复发生动脉、静脉血栓或和习惯性流产为临床表现，伴持续性抗磷脂抗体（antiphospholipid antibody APL）或抗132糖蛋白Ⅰ（β2GPI）抗体阳性，且多系统受累的非炎症性自身免疫性疾病，又称抗磷脂-血栓综合征 （antiphospholipid- thrombosis syndrome , APE-T）。 APS 分原发性和继发性两类，前者无任何诱因，后者多继发于系统性红斑狼疮（systemic lupus erythematosus，SLE）、类风湿性关节炎、干燥综合征等结缔组织疾病，也可继发于各种感染与肿瘤等。
