BACKGROUND: The current EAACI/GA(2)LEN/EDF/WAO guideline for urticaria provide specific recommendations for the diagnostic workup and treatment of patients with chronic spontaneous urticaria (CsU). This study explored if physicians in Ecuador know these recommendations and implement them in their actual clinical practice for CsU. METHODS: We investigated physicians who treat CsU patients in a cross-sectional study using a standardized questionnaire. Descriptive statistics were employed, adjusted logistic regression was performed to assess the link of guideline knowledge and use of therapy...

BACKGROUND: Chronic spontaneous urticaria (CSU) can be debilitating, difficult to treat, and frustrating for patients and physicians. Real-world evidence for the burden of CSU is limited. The objective of this study was to document disease duration, treatment history, and disease activity, as well as impact on health-related quality of life (HRQoL) and work among patients with inadequately controlled CSU, and to describe its humanistic, societal, and economic burden. METHODS: This international observational study assessed a cohort of 673 adult patients with CSU whose symptoms persisted for ≥12 months despite treatment...

PURPOSE OF REVIEW: The international EAACI/GALEN/EDF/WAO guideline suggests a stepwise approach for the therapeutic management of chronic spontaneous urticaria (CSU), outlined in an algorithm. The aim of this article is to summarize and review the evidence available on alternative treatment options for CSU outside of this algorithm. RECENT FINDINGS: Although CSU is a common disease, there are a limited number of high-quality studies, and only antihistamines and omalizumab are licensed for its treatment...

There was no previous population-based study on the comparison of the risk of chronic spontaneous urticaria (CSU) between autoimmune thyroid diseases (AITD) and age- and gender-matched controls. The primary objective of this study was to evaluate the risk of CSU after diagnosis of AITD using national registry data from Korea. The secondary objective was to evaluate other risk factors of CSU. Based on the disease code diagnoses in 2003-2005, we composed an AITD group (n=3,659) and an age- and gender-matched control group (n=18,295)...

Chronic urticaria (CU) is defined by episodes of urticaria with or without angioedema, which recur daily or nearly daily over more than 6 weeks. Sudden manifestations of CU with or without known causes are termed chronic spontaneous urticaria, which is differentiated from chronic inducible urticaria. The differential diagnoses of CU in childhood range from self-limiting dermatoses to severe systemic diseases. Further targeted steps are taken to detect potential trigger factors or underlying illnesses only if suspicion arises on anamnestic grounds and CU is best treated in accordance with international guidelines...

Increased filaggrin expression was found to be correlated with severity scores in chronic spontaneous urticaria (CSU); however, the role of filaggrin breakdown products (FBPs) in CSU has not been studied. We collected stratum corneum (SC) specimens from the volar forearms of 10 CSU patients, 10 AD patients, and 10 healthy normal controls (NCs) and measured contents of FBPs (pyrrolidone carboxylic acid [PCA] and urocanic acid [UCA]) using UPLC-MS/MS, transepidermal water loss (TEWL) and epidermal pH. Compared to NCs, cis-UCA level was increased in CSU lesions (P < 0...

Chronic urticaria (CU) is a disease characterised by pruritic weals, angio-oedema or both occurring for at least 6 weeks. It encompasses spontaneous and inducible urticarias. The national and international guidelines outline the principles of treatment. Omalizumab, an anti-immunoglobulin E monoclonal antibody has transformed the management of many severe and treatment-refractory patients. However, current UK guidance on its use does not address the needs of those with less severe disease, inducible urticarias, idiopathic histaminergic angio-oedema without weals as a presentation of CU and omalizumab non-responders...

Background. Treatment with omalizumab, a humanized recombinant monoclonal anti-IgE antibody, results in clinical efficacy in patients with Chronic Spontaneous Urticaria (CSU). The mechanism of action of omalizumab in CSU has not been elucidated in detail. Objectives. To determine the effects of omalizumab on levels of high affinity IgE receptor-positive (FcεRI(+)) and IgE-positive (IgE(+)) dermal cells and blood basophils. Treatment efficacy and safety were also assessed. Study design. In a double-blind study, CSU patients aged 18‑75 years were randomized to receive 300 mg omalizumab (n=20) or placebo (n=10) subcutaneously every 4 weeks for 12 weeks...

BACKGROUND: The knowledge about chronic spontaneous urticaria (CSU) phenotypes is based on its clinical characteristics, associated comorbidities, course of the disease and its response to the available effective drugs. Genotype expression and its further correlation with CSU phenotypes are still unknown. We describe the cutaneous transcriptome of patients suffering a severely active CSU refractory to antihistamine treatment. METHODS: Through the bioinformatic analysis of the whole Human Genome with Oligo Microarrays and Quantitative real-time polymerase chain reaction (qPCR), relevant genes expressed in non-lesional [NLS-CSU] and lesional skin [LS-CSU]) and peripheral blood were identified in 20 patients suffering from severely active CSU and 10 healthy controls (HCs) RESULTS: From 39 genes differentially expressed in NLS-CSU when compared with HCs, 31 (79...

REVIEW
P Kolkhir, M Metz, S Altrichter, M Maurer
Patients with chronic spontaneous urticaria (CSU) are widely held to often have other autoimmune disorders, including autoimmune thyroid disease. Here, we systematically evaluated the literature on the prevalence of thyroid autoimmunity in CSU and vice versa. There is a strong link between CSU and elevated levels of IgG antithyroid autoantibodies (AAbs), with most of a large number of studies reporting rates of ≥10%. Levels of IgG against thyroid peroxidase (TPO) are more often elevated in CSU than those of other IgG antithyroid AAbs (strong evidence)...

BACKGROUND: Nonsedating antihistamines are the treatment of choice for chronic spontaneous urticaria (CSU), while omalizumab and immunosuppressants have also been approved as an add-on treatment. Autologous whole-blood injection (AWBI) has been used in previous studies with ambiguous results. The aim of our study was to evaluate changes in the Urticaria Activity Score (UAS7), Dermatology Life Quality Index (DLQI), and Chronic Urticaria Quality of Life (CU-Q2oL) score, and also the association of serologic markers with disease severity measures after AWBI...
