BACKGROUND The etiology of chronic idiopathic urticaria (CIU) is not completely clear. There are a few antibodies were reported to correlate with CIU. OBJECTIVE To investigate the correlation these antibodies and CIU. METHODS The autologous serum skin test (ASST) and allergens were performed. Serum levels of immunoglobulin E (IgE), anti-FcεRI and anti-IgE, anti-Helicobacter pylori (HP) anti...

Summary Background. Histamine release (HR) test has previously been shown to predict the presence of endogenous histamine-releasing factors in chronic spontaneous urticaria (CSU). Objectives and methods. Twenty CSU patients unresponsive to antihistamine treatment were enrolled in order to evaluate the correlations between HR test results and demographic features, quality of life, disease activi...

Eotaxin is a potent agonist for CC chemokine receptor 3 that can attract eosinophils at sites of inflammation. Given the potential role of eosinophils in chronic spontaneous urticaria (CU), we measured serum eotaxin levels together with C-reactive protein in 100 CU patients who were characterized according to autologous serum skin test (ASST) and disease severity. Serum eotaxin concentration wa...

INTRODUCTION The basophil activation test showing CD63 up regulation could be a specific and sensitive in vitro complementary text to the in vivo autologous serum skin test for the activity assessment of the patients suffering autoimmune chronic spontaneous urticaria. The aim of this study is to define the basophil activation test as a useful tool in clinical practice in order to identify those...

BACKGROUND Beside autoimmunity, coagulation pathway is also involved in the pathogenesis of chronic urticaria (CU). Previous studies showed that plasma D-dimer levels paralleled the severity of the disease. To date, there are no data concerning D-dimer level in Thai patients with CU. OBJECTIVE This study aimed to find the relationship between plasma D-dimer levels and the disease severity of ...

Background. Chronic urticaria is defined as urticaria persisting daily for more than six weeks. A significant number of patients had autoimmune basis where autologous serum skin test is widely used for detection of chronic autoimmune urticaria. Objectives. To estimate the frequency of autoimmune urticarial in Iraqi patients utilizing the autologous serum skin test and to evaluate its results wi...

BACKGROUND Autoimmune mechanisms play an important role in the pathophysiology of chronic urticaria (CU), and the autologous serum skin test (ASST) helps to identify patients with autoreactive CU. One of the factors involved in autoreactive mechanisms is the cell surface receptor programmed death-1 which is encoded by the programmed cell death 1 gene (PDCD1). OBJECTIVE To investigate whether ...

BACKGROUND Chronic urticaria is termed as idiopathic if there is an absence of any identifiable causes of mast cell and basophil degranulation. Various cytokines have been found to be involved in inflammatory processes associated with chronic idiopathic urticaria, including interleukin (IL) 18 and IL-6. OBJECTIVE To evaluate any possible correlation of IL-18 and IL-6 cytokines with the clinic...

BACKGROUND The precise pathogenesis of chronic spontaneous urticaria (CSU) remains unknown. However, an important association between CSU and autoimmune disorders such as Hashimoto's disease (HD) has been reported. We investigated the frequency of HD as a comorbidity of CSU and the prevalence rate of autoreactivity among CSU patients with HD. PATIENTS AND METHODS The presence of thyroid autoa...
