Introduction: Urticaria and angioedema belong to a heterogeneous group of diseases and it is often very difficult to determine the specific cause of clinical symptoms. Coagulation factors play an important role, and patients with chronic urticaria have elevated plasma concentrations of coagulation factor VII, prothrombin fragment 1 + 2 and D-dimers.
Aim: To assess the relationship between the severity of clinical symptoms of chronic urticaria and serum D-dimer levels.
Material and methods: Sixty patients with a diagnosis of chronic spontaneous urticaria, diagnosed and treated in the Dermatology Department of the Poznan University of Medical Sciences were qualified for the tests. The control group consisted of 35 healthy volunteers. All patients with chronic spontaneous urticaria were previously subjected to individual stages of the diagnostic process, in accordance with the guidelines of EAACI and the Polish team of specialists in the field of dermatology and venereology, and allergology. The dermatological condition was assessed using the UAS scale. The serum D-dimer concentration was determined by immunoturbidimetry.
Results: In the basic group, statistically significant, positive and high correlations between the serum D-dimer concentration and the severity of urticaria symptoms were shown, as well as between the severity of pruritus and the value of the disease activity index were shown.
Conclusions: Elevated levels of D-imers are significantly correlated with the severity of urticaria.
Keywords: D-dimers; treatment; urticaria.
