The urticaria activity score (UAS) is the gold standard for assessing disease activity in patients with chronic spontaneous urticaria (CSU). Two different versions, the UAS7 and UAS7TD , are currently used in clinical trials and routine care. To compare both versions and to obtain data on their interpretability, 130 CSU patients applied both versions and globally rated their disease activity as none, mild, moderate, or severe. UAS7 and UAS7TD values correlated strongly (r=0.90, P<0.001). Interquartile ranges for UAS7 and UAS7TD values for mild, moderate and severe CSU were 11-20 and 10-24, 16-30 and 16-32, and 27-37 and 28-40...

BACKGROUND: Chronic urticaria has an expressive prevalence in general population, especially in adults, and is defined by the presence of intermittent hives for six weeks or longer. Our study aims to characterize the histological patterns of chronic spontaneous urticaria, based on the inflammatory cell infiltrate, and correlate them to laboratory exams. METHODS: It was performed a retrospective analysis of laboratory, histopathology and direct immunofluorescence data of 93 patients with chronic urticaria...

According to current guidelines, non-sedative H1-antihistamines (nsAH) are the first-line therapy of chronic spontaneous urticaria (CSU). But even up-dosed antihistamines (to four times the standard dose) produce symptom resolution in less than 50% of patients. Biomarkers that can predict the response to nsAH are still unknown. We carried out a prospective study and used discriminant analysis to evaluate the combination of D-dimer, fibrinogen, C-reactive protein and ESR values for predicting the outcome of treatment with levocetirizine in 84 CSU patients...

Omalizumab has recently obtained indication for chronic spontaneous urticaria both in the US and Europe. However, the mechanism of action of this drug has yet to be fully elucidated. Previous studies have shown elevations in cytokine serum levels in patients with chronic spontaneous urticaria, and it is not known whether omalizumab treatment may affect cytokine serum levels in this condition. Besides, a proportion of chronic spontaneous urticaria patients have concomitant atopy, which may be associated, at least in theory, with prevalence of serum Th2-type cytokines...

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 activity, clinical course, and autologous serum and plasma skin tests (ASST and APST). Results. All patients with positive HR test (9/9, 100%) had a more severe disease activity at onset (urticaria activity score, UAS > 2) when compared to negative HR test patients (5/11; p = 0...

Monoclonal anti-IgE antibodies (omalizumab) are able to induce clinically significant benefits in patients with severe chronic spontaneous urticaria (CS). Those results led clinicians and investigators to reconsider a possible pathogenic role not previously supported for IgE and its receptors in this disease, and to investigate additional approaches for understanding its pathogenesis. IgE antibodies to unknown environmental allergens able to trigger chronic urticaria are not generally regarded as the etiologic factor for the disease...

Chronic urticaria is a spontaneous or inducible group of diseases characterized by the occurrence of wheals (and, in about half of cases, angioedema) for more than 6 weeks. These are rather frequent conditions that may severely affect patients' quality of life and sometimes represent a challenge for doctors as well. The causes of chronic urticaria are still poorly defined, although there is growing evidence that different biologic systems including immunity, inflammation, and coagulation may take part in the pathomechanism eventually leading to mast cell and basophil degranulation and hence to wheal formation...

BACKGROUND: Omalizumab, a recombinant anti-IgE antibody, effectively treats chronic spontaneous urticaria. Evidence is lacking in chronic inducible urticarias (CIndUs), which are frequently H1-antihistamine resistant. OBJECTIVE: We aimed to determine, from the current published literature, the strength of evidence for omalizumab efficacy and safety in the treatment of CIndUs. METHODS: We performed a PubMed® search to identify evidence on omalizumab use in the following nine CIndU subtypes: symptomatic dermographism, cold urticaria, delayed pressure urticaria, solar urticaria, heat urticaria, vibratory angioedema, cholinergic urticaria, contact urticaria and aquagenic urticaria...

Urticaria is a common, mast cell-driven disease presenting with wheals or angioedema or both. In the last years, urticaria has increasingly attracted notice to clinicians and researchers, last but not least inspired by the approval of omalizumab, an anti-IgE antibody, for urticaria treatment. There is wide consensus on the clinical classification based on duration and elicitation. However, the pathogenesis is incompletely understood. This review summarizes current guidelines for the management and novel insights in the pathogenesis of urticaria with special focus on their impact on clinical praxis...

Chronic spontaneous urticaria (CSU) is a condition presenting as the spontaneous occurrence of itchy weals with or without angio-oedema for > 6 weeks. A patient with severe chronic spontaneous urticaria who developed resistance to omalizumab is described. The patient's D-dimer plasma levels strictly paralleled the disease activity despite the administration of anti-IgE therapy.

Chronic idiopathic urticaria (CIU) is one of the mysteries of dermatology. An association between spontaneous CIU and contact allergy sensitization is possible. In this study, we aimed to test the hypothesis that contact allergy might play a role in disease in CIU patients. Furthermore, we examined if patch testing should be routinely performed in patients with chronic urticaria (CU). Ultimately, we concluded that patch testing should be included among the diagnostic procedures for CU.

Little is known about the role of the kallikrein-kinin system in chronic spontaneous urticaria (CSU). Kallikrein 5 (KLK5), a trypsin-like enzyme, is the most abundant in the skin and plays a role in itching and inflammatory reaction. In this study, we determined plasma KLK5 concentration, and its associations with acute phase response in CSU patients. Concentrations of KLK5 in plasma and CRP in serum were measured in patients with CSU of varying severity and in the healthy subjects. Plasma KLK5 concentrations were significantly lower in CSU (all) and moderate-severe CSU patients, as compared with the controls...

Chronic urticaria is a disease manifested by a pruritic rash lasting longer than 6 weeks that may severely affect quality of life and daily function. Chronic urticaria can be further divided into chronic spontaneous urticaria which appears without a trigger and chronic inducible urticaria which evolves following distinct physical triggers. These two clinical manifestations could coexist in the same patient. The pathogenesis of chronic urticaria is not fully elucidated, although it is considered an autoimmune disease in at least 50% patients that produce auto- IgG antibodies targeted against the high affinity Fc receptor and to a lesser extent against IgE itself...

A long and winding road led to the discovery of immunoglobulin E (IgE) in 1966 and 1967. We are currently on a long and winding road to understand the immunologic basis of the clinical effects of the anti-IgE antibody omalizumab in asthma. It is possible that patients with asthma (as patients with chronic spontaneous urticaria) benefit in different immunologic ways from omalizumab treatment. This article reviews the history of IgE discovery and current concepts of anti-IgE therapy in asthma.
