Chronic spontaneous urticaria (CSU) is a frequent disorder with recurrent itchy wheals and/or angioedema, and nearly 35% patients respond poorly to nonsedating H1 antihistamines treatment. CRP gene encodes the C reactive protein, which is involved in the pathogenesis of CSU. To investigate the impacts of CRP polymorphisms on the susceptibility and therapeutic efficacy in the South Han CSU patients, we enrolled 145 CSU patients in our study. After 4-week nonsedating H1 antihistamine monotherapy treatment, more than 50% reduction of the severity score is considered as effective, or else non-effective...

BACKGROUND: Several dermatoses are mediated by histamine, such as urticaria, angioedema, and papular urticaria. There are no Brazilian studies comparing the potency of antihistamines. OBJECTIVES: To evaluate the tolerability and efficacy of the main commercial brand and generic H1 antihistamines, regarding the suppression of the wheal and flare to the histamine test. METHODS: A quasi-experimental, open study with 10 healthy adults submitted to the histamine test on the ventral aspect of the forearms...

BACKGROUND: : Chronic urticaria (hives) affects a sizeable number of people worldwide, perhaps as much as 3%. It is often accompanied by angioedema. The negative effects of urticaria and angioedema, and any adverse effects of treatment, can result in significant patient burden. OBJECTIVE: : To explore patients' use of, preferences for, and willingness to switch from prescription to over-the-counter (OTC) treatments for chronic urticaria. In addition, we compared treatment satisfaction with the treatment used most recently for their chronic urticaria...

Urticaria is a heterogeneous group of debilitating skin disorders characterized by wheals, pruritus, and frequently angioedema. The various forms of urticaria are often chronic and can exact a toll on quality of life. New diagnostic criteria and management guidelines are available to assist primary care physicians in the identification and proper treatment of different subtypes of urticaria. Second-generation antihistamines are recommended as first-line therapy because of their high degree of efficacy and safety...

BACKGROUND: Chronic idiopathic urticaria is a clinic entity that is manifested by wheals of more than six weeks of evolution, without identification of the causing agent, and sometimes resistant to conventional treatment. There are improvements with leukotriene receptor antagonists. OBJECTIVE: To evaluate the clinical efficacy of montelukast and desloratadine individually and combined, compared with hydroxicine. PATIENTS AND METHODS: The trial included 40 subjects with chronic idiopathic urticaria referred from the outpatient allergy service...

Chronic idiopathic urticaria (CIU) manifests as frequently occurring, short-lived wheals, surrounded by a bright-red flare, and often accompanied by angioedema. The cause of CIU is undefined and its diagnosis requires exclusion of other conditions with somewhat similar symptoms. Recent evidence has indicated that IgG autoantibodies directed against high-affinity IgE receptors (FcepsilonRI) may be involved in the pathophysiology of CIU. Following the release of mast cell or basophil-derived histamine, this mediator binds to H(1) and H(2) receptors, leading to vasodilatation and increased vascular permeability...

Chronic urticaria is now recognized as an autoreactive disorder in a substantial fraction of patients. A serologic mediator of whealing has been demonstrated in 50-60% of patients with chronic urticaria, and autoantibodies against the high affinity IgE receptor or IgE have been detected in about half of these patients. The demonstration that chronic urticaria is frequently autoimmune has encouraged a more aggressive therapeutic approach, with the use of immunomodulatory drugs.A step-by-step approach to the management of chronic urticaria is proposed, based on our personal experience and review of current medical literature, identified through Medline research and hand searching in medical journals...

Urticaria is defined by weals (hives), with or without angioedema, that appear and peak in minutes to hours, usually disappear within 24 h, and are accompanied by pruritus that worsens during the night. Urticaria is caused by cutaneous mast cell degranulation, attributed to immunological, nonimmunological, and idiopathic causes. Chronic idiopathic urticaria (CIU) is the diagnosis when the pathophysiological mechanism of persistent urticaria remains unclear; up to half of patients with CIU have functional autoantibodies directed against the high-affinity receptor for IgE (FcepsilonRI) or against IgE itself, which appear to induce mast cell degranulation...

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 ephedrine as a local spray is very useful for oropharyngeal edema. H1 antihistamines with a low potential for sedation are the most important first-line treatment...
