凝血因子与荨麻疹的关系

荨麻疹是一种常见的、复发性的皮肤病.其发病机制复杂,至今尚未完全清楚.近年来有学者提出荨麻疹发病可能与凝血状态有关,并对凝血酶原片段F1+2、D二聚体、因子Ⅶ和因子Ⅻ等凝血因子进行相关研究,认为慢性荨麻疹患者体内存在外源性凝血级联反应激活以及纤溶状态,凝血酶生成可能在荨麻疹的发病中起着作用.抗凝治疗在荨麻疹药物治疗中显示出一定的临床应用前景.     

凝血因子与荨麻疹的关系

Urticaria is a common, recurrent and refractory skin disease. The exact pathogenic mechanism of urticaria is complex and unclear. It has been proposed that the development of urticaria is associated with coagulation status. Related studies on thrombinogen fragment F (1+2), D dimmer, factor Ⅶ and factor Ⅻ revealed the activation of extrinsic pathway of coagulation cascade and signs of fibrinolysis in patients with chronic urticaria. Thromhin generation may play a key role in the pathogenesis of urticaria. And anticoagulant drugs have exhibited a good prospect in the medication of urticaria.

慢性荨麻疹与凝血机制的研究进展

凝血机制在慢性荨麻疹的发病中起着重要的作用。内、外源性凝血途径同时被激活,产生凝血酶。凝血酶是一种蛋白酶激活受体激动剂,可诱导肥大细胞释放组胺,从而诱发荨麻疹的发生。其病情严重性随着凝血因子数量的增高而加重。抗凝药物及蛋白酶抑制剂对部分难治性荨麻疹有一定疗效。概述近几年针对凝血机制治疗慢性荨麻疹的研究进展。     

炎症因子及凝血因子与慢性荨麻疹发病及预后的相关性

目的：分析慢性荨麻疹患者血液学指标与发病及预后的相关性。方法：检测138例慢性荨麻疹患者及100例正常对照的血清总IgE、CRP、补体C3、补体C4、D2聚体、F1+2片段、FVIIa水平,并进行多因素Logist回归分析。结果：慢性荨麻疹患者血清中总IgE值、补体C3、C4、CRP、F1+2片段、FVIIa 及D2聚体与水平显著高于对照组,差异具有统计学意义( P＜0.05);87例慢性荨麻疹患者抗组胺药物治疗3个月后有效,其CRP、FVIIa、D2聚体、疾病严重程度评分明显高于治疗有效组,差异具有统计学意义( P＜0.05)。慢性荨麻疹抗组胺治疗无效组进行多因素Logist回归分析示D2聚体为治疗抵抗的主要影响因素（OR：1．63,95％CI 1.102-1.799,P<0.05）。以D2聚体的中位数（5.41 mg/L）分为两组,A组（≥5.41 mg/L）,B组（＜5.41 mg/L）,治疗后随访2年显示A组的复发率（23.56%）明显高于B组（12.14%）,差异具有统计学意义（P）＜0.001）。结论：多种炎症因子及凝血因子可能参与慢性荨麻疹的发病;D2聚体水平可能与慢性荨麻疹治疗的疗效及复发相关。
