Sir, Urticaria is an immunologically mediated hypersensitivity reaction developing in both sexes. Although it may occur at any age, young females are more frequently affected [1]. Acute urticaria, shorter than six weeks, generally self-limited. In contrast, a patient with urticaria lasting weeks classified as having chronic urticaria. Patients be into either inducible or spontaneous (CSU). true...
The aim of this Global Allergy and Asthma European Network (GA(2)LEN) consensus report is to provide recommendations and suggestions for assessing patient-reported outcomes (PROs) including health-related quality of life in patients with urticaria. We recommend that PROs should be used both in clinical trials and routine practice for the evaluation of urticaria patients. We suggest that PROs sh...
BACKGROUND In spite of the frequency of chronic urticaria there are very few epidemiological studies of its prevalence and distribution. OBJECTIVE We wanted to approach the real prevalence of chronic urticaria in a population-based study and to depict demographic distribution and personal perception of the disease. We also wanted to describe the frequency of acute urticaria episodes in the po...
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...
Seasonal Exacerbation of Asthma Is Frequently Associated with Recurrent Episodes of Acute Urticaria.
BACKGROUND Asthma and urticaria are both partially mediated by an increased release of histamine from highly activated mast cells. They are pathophysiologically different, as mast cell degranulation in these 2 disorders results from different mechanisms. OBJECTIVE To assess the incidence of urticaria in patients with asthma, and of asthma in patients with chronic spontaneous urticaria (CSU). ...
Blood eosinophils and serum eosinophil cationic protein in patients with acute and chronic urticaria
We have analysed the relationship of blood eosinophil count and serum eosinophil cationic protein (ECP) levels in patients with acute and chronic idiopathic urticaria. The ECP levels and eosinophil counts were measured in the peripheral blood of 15 patients with acute urticaria, 25 with chronic idiopathic urticaria and 10 normal healthy subjects. Blood eosinophil counts and serum ECP levels inc...
BACKGROUND The majority of patients with cholinergic urticaria presents with strong hypersensitivity to autologous sweat. Patients with severe cholinergic urticaria are frequently resistant to H(1) antagonists which are used in conventional therapies for various types of urticaria. It has been reported that desensitization using partially purified sweat antigen was effective in a patient with c...
Introduction Urticaria and angioedema lasting more than 6 weeks have been designated as chronic urticaria (CU). It encompasses two major subtypes: chronic spontaneous urticaria (CSU) (previously known as chronic idiopathic urticaria) (CIU) and chronic inducible urticaria. CSU has been defined as wheals and/or angioedema that are endogenous and independent of any external physical stimulus. It a...
INTRODUCTION The term "urticaria" refers to any of a group of distinct skin conditions that are characterized by itchy, wheal-and-flare skin reactions (hives). In spontaneous urticaria, the most common type, the hives seem to arise without provocation. METHODS Selective review of the literature, including current guidelines. RESULTS Spontaneous urticaria is divided into acute (lasting less ...
BACKGROUND Bupropion, which is widely used in patients with depressive disorder, may cause allergic reactions. However, the real prevalence of these side effects may be overlooked and underreported due to the delayed onset phenomenon. OBJECTIVE This study aimed to estimate the real incidence of bupropion-induced urticaria and clarify the delayed onset phenomenon. METHODS We conducted a nati...
