“…To evaluate dermographism, firm stroking of the skin was performed using a dermographometer with a pressure of 4900 gm/cm 2 , which induced linear itchy wheals within minutes 10 . The test for delayed pressure urticaria was performed using sandbags joined by a rope weighing 15 lb each placed over one shoulder for 15 min, which resulted in a palpable wheal at the application site 2–8 h later 11 . Diagnosis of cold urticaria was made by application of an ice cube in a thin plastic bag to the skin of the forearm for 20 min which caused whealing to occur within 15 min at the test site, on rewarming the skin 12 .…”

The purpose of our study was to assess the prevalence and clinical course of patients with chronic idiopathic urticaria (CIU), as well as possible causes or associated findings, laboratory findings and the duration of the disease in patients with chronic urticaria (CU). We retrospectively reviewed the 450 case record forms of patients with CU and/or angioedema who attended the Department of Dermatology, Siriraj Hospital, during the period 2000-2004. Of 450 patients with CU, 337 patients (75%) were diagnosed as CIU. Forty-three patients (9.5%) had physical urticaria, while 17 patients (3.8%) had infectious causes. Other possible causes were food, thyroid diseases, atopy, drugs, dyspepsia and collagen vascular diseases. In eighty-nine percent of patients, no abnormalities were detected at the time of physical examination. The most common abnormal laboratory finding was minimal elevation of the erythrocyte sedimentary rate (42%). In 61 patients, autologous serum skin tests had been done. Fifteen patients (24.5%) had positive results i.e. autoimmune urticaria. Anti-thyroglobulin and anti-microsomal antibodies were positive in 16 % and 12% of CIU patients respectively. After 1 year from the onset of the symptoms, 34.5% of CIU patients were free of symptoms and after 1.2 years from the onset of the symptoms, 56.5% of autoimmune urticaria patients were free of symptoms. The median disease duration of CIU and autoimmune urticaria were 390 days and 450 days respectively. Our study provided an overview of CU and CIU in a large series of Thai patients, based on etiological aspects and clinical courses.

“…Therefore, no conclusions could be drawn to relate IL‐6 concentration to CRP scores upon the disease activity. The so‐called pure DPU is very rare (about 94% of patients with DPU suffer from concomitant chronic urticaria) 10 . Exclusion of patients suffering from DPU concomitant with chronic urticaria would hamper interpretation of the results, as patients with chronic urticaria showed both increased IL‐6 6,7 and CRP 7,8 concentrations.…”

“…The main limitation of this study is a small sample, basically because of low incidence of pure DPU. Pure DPU is uncommon as about 94% of DPU patients suffer from the co‐occurring CU 7 . Selection of such a homogenous group makes it possible to avoid the impact of the co‐existent CU upon the d ‐dimer evaluation result.…”

“…Asero et al. suggested that activation of coagulation is involved in the pathogenesis of chronic urticaria 3,7 . Thrombin and other products of coagulation/fibrinolysis cascade may play a key role in the urticarial processes, by both mast cell activation and increasing vascular permeability 8 .…”
