Abstract:

Dysregulation of the coagulation cascade and fibrinolysis system may play an etiologic role in many diseases. Allergic diseases such as bronchial asthma, atopic dermatitis, and conjunctivitis are also associated with fibrin accumulation caused by a change in hemostasis. However, only a few studies have dealt with the relationship between allergic rhinitis (AR) and the coagulation system. We investigated the difference of coagulation and fibrinolysis cascade components between an AR mouse model and a control mice. BALB/c mice were sensitized and challenged with ovalbumin. Multiple parameters of coagulation cascade and fibrinolysis system such as factors II, V, VII, X, and XIII; tissue-type plasminogen activator; urokinase-type plasminogen activator (u-PA); plasminogen activator inhibitor-1 (PAI-1); and fibrin were compared between the AR model group and the control group. The symptom scores and eosinophil counts were higher in the AR group than in the control group (P?<?.01). The mRNA expression level of u-PA (P?=?.040) was significantly lower, and the expression levels of factor II (P?=?.038) and factor X (P?=?.036) were significantly higher, in the AR group. Immunohistochemical staining revealed that most of the fibrinolysis system and coagulation cascade components were localized to the epithelium, endothelium, and submucosal glands of the nasal mucosa. u-PA was downregulated in the AR group, whereas fibrin deposition was more prominent in the AR group than in the control group. In AR, particular components of the coagulation cascade were increased and fibrinolysis system was decreased compared to normal control. This difference may be associated with the fibrin deposition in the mucosa of AR mouse model
