Sir, Chronic idiopathic urticaria (CIU) is defined as the occurrence of wheals on most days for more than 6 weeks in the absence of any known causative or triggering agents (1). Most cases of chronic urticaria are classified as ‘idiopathic’, despite intense efforts to determine any aetiological factor, and require long-term treatment with H1-receptor antagonists, which are the first-line approa...

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...

Chronic idiopathic urticaria (CIU) is a common skin condition that affects 0.1-3 % of people in the USA and Europe and accounts for nearly 75 % of all chronic urticaria cases. Up to 40 % of patients who have chronic urticaria for more than 6 months still have urticarial wheals 10 years later. The therapeutic management should first be oriented towards palliation of symptoms. A 2 % solution of e...

Chronic urticaria is a common condition that can be very disabling when severe. A variety of causes has been reported to induce urticaria, including food, infections, drugs and other factors. In more than 50% of cases of chronic urticaria, however, the cause remains unknown and cannot be ascribed to allergic, physical, environmental or other factors. Although an association between chronic idio...

intradermal injection of autologous serum and plasma elicit a cutaneous reactivity in almost 45-60% of patients with chronic idiopathic urticaria (ciu).   this reactivity is associated with the presence of auto antibodies against ige or ige receptors. this study was carried out to compare the cutaneous reactivity of autologous serum and plasma skin tests in a series of patients with ciu for dia...

BACKGROUND: Controlled trials have demonstrated the efficacy of antihistamines in the treatment of chronic idiopathic urticaria. Second-generation antihistamines are recommended as first-line therapy for chronic idiopathic urticaria. The purpose of this study was to determine the effect of desloratadine, a newer, nonsedating, second-generation antihistamine, on symptoms of chronic idiopathic ur...

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...

Background: Urticaria is very common and most of the current treatments are only partially successful. Objective: As the efficacy of acupuncture in the treatment of chronic urticaria has not been studied in Iran, we decided to do this study. Patients and Methods: In a randomized, controlled, double-blind clinical trial, 40 patients with chronic urticaria referred to skin clinics of Isfahan Univ...

Chronic urticaria (CU) is a skin condition characterized by the presence of intensively pruritic lesions occurring intermittently or continuously for more than 6 weeks. Because the cause(s) of CU are often not known, it is usually referred as chronic spontaneous urticaria (CSU) or chronic idiopathic urticaria (CIU). It affects 0.1%–0.3% of children. Moreover, solar urticaria (SU) is a rare chro...
