Abstract
BACKGROUND Urticaria mostly occurs acutely with a very high probability of spontaneous remission. When it persists for more than 6 weeks a chronic urticaria is manifest, which occurs either spontaneously or inducible by specific triggers. The underlying mechanisms are not fully understood but recent research points to defined pathogenetic factors. QUESTION AND AIM Whether spontaneous remission is possible in urticaria is summarized descriptively in this review, and suggestions are given for the "step down" of urticaria treatment after remission. The mechanisms including autoallergic, immunoglobulin E (IgE)-dependent type I reactions and autoimmune, activating IgG-dependent type IIb reactions are presented. These are discussed in the context of spontaneous remission and the possibilities of induced remission.

Abstract
INTRODUCTION Urticaria, a mast cell-mediated skin disease, manifests as acute or chronic, with the latter divided into spontaneous and inducible types and requires individualized management, including identifying triggers and comorbidities. Antihistamines, particularly the second generation group, form the mainstay of primary treatment plans consisting of dosage adjustments and/or in combination with other treatment modalities depending on underlying disease control. AREAS COVERED A literature search was conducted using 'antihistamines,' 'urticaria,' 'pharmacogenomics,' 'genomics,' 'biomarkers' and 'treatment response' as key words. In this review, we focus on the comprehensive understanding and application of antihistamines in managing adult and adolescent patients with chronic urticaria. EXPERT OPINION Using antihistamines to treat urticaria is set to change significantly, focusing more on personalized medicine and identifying key biomarkers to enhance treatment response prediction. These changes aim to make treatments more specific and cost-effective by avoiding unnecessary tests. Applying new approaches in everyday clinical care faces challenges like proving the biomarkers' reliability, updating current guidelines, and incorporating individualized treatments into standard procedures. Efforts should now concentrate on finding easy-to-use biomarkers, improving access to pharmacogenomics, understanding why some patients are resistant to treatment, and creating more specific treatment options based on patient needs.

A comparative analysis of chronic inducible urticaria in 423 patients: Clinical and laboratory features and comorbid conditions. J Eur Acad Dermatol Venereol 2024; 38:513-520. [PMID: 37991240 DOI: 10.1111/jdv.19637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Accepted: 10/26/2023] [Indexed: 11/23/2023]
Abstract
BACKGROUND Chronic inducible urticaria (CIndU) is a subtype of chronic urticaria (CU) which require specific physical or non-physical triggers to occur. They may be isolated or may coexist with chronic spontaneous urticaria (CSU). Despite their frequent appearance in dermatology clinics, there is scarce information on the distinguishing features among the most common subtypes of CIndU as well as isolated CIndU versus CSU plus CIndU. OBJECTIVES To compare clinical and laboratory characteristics, and comorbid conditions among the most common CIndU types and isolated CIndU versus CSU plus CIndU. METHODS We retrospectively analysed CIndU patients and compared patients' demographic, clinical and laboratory characteristics across isolated CIndU, CSU plus CIndU, symptomatic dermographism (SD), cold urticaria (ColdU) and cholinergic urticaria (ChoU). RESULTS A total of 423 patients (~70% isolated CIndU, ~30% CSU plus CIndU, ~5% mixed CIndU subtypes) were included in the study. The most frequent CIndU subtypes were SD (68.6%; 290/423), ColdU (11.4%; 48/423) and ChoU (10.9%; 46/423). Isolated CIndU patients were younger than CSU plus CIndU (33.74 ± 12.72 vs. 37.06 ± 11.84, p = 0.010). Angioedema, emergency referrals, need for systemic steroids, comorbid systemic disorders were more frequent and baseline urticaria control test scores were lower in CSU plus CIndU patients (vs. CIndU, p < 0.001, p = 0.008, p < 0.001, p = 0.031, p = 0.036, respectively). Among CIndU subtypes, ChoU patients were younger (24.9 ± 12.2 vs. 34.47 ± 12.12 vs. 31.38 ± 14.95; p < 0.001) and had male predominance (p < 0.001) while SD patients had no angioedema (p < 0.001) and had higher frequency of increased total IgE levels (p = 0.006). CONCLUSIONS Isolated CIndU and CSU plus CIndU seems to be different endotypes of CU where CSU plus CIndU presents a more severe and refractory course. There are distinctive features of each CIndU subtype. These suggest involvement of different pathomechanistic pathways in these subtypes that need to be clarified in future studies.

Abstract
BACKGROUND Patients with chronic spontaneous urticaria (CSU) can have comorbid inducible urticaria (CIndU). How comorbid CIndU affects patients and their CSU is largely unclear. OBJECTIVE To compare patients with CSU with and without comorbid CIndUs for differences in demographic features, clinical characteristics, and laboratory markers. METHODS We analyzed 708 patients with CSU of our Urticaria Center of Reference and Excellence enrolled in CURE, the chronic urticaria registry. CURE data collected until October 2022 were used to compare patients with and without comorbid CIndU for their demographic characteristics, disease onset, activity, impact, and control, as well as concomitant allergic and autoimmune diseases and laboratory parameters associated with autoimmune CSU. RESULTS Of 708 patients with CSU, 247 (35%) had comorbid CIndU. Compared with patients with standalone CSU, patients with CSU with comorbid CIndU were significantly younger, had earlier disease onset, longer disease duration, higher impact on quality of life, and a higher rate of concomitant allergic diseases. Moreover, patients with CSU with comorbid CIndU less often had features linked to autoimmune CSU such as angioedema, concomitant autoimmune diseases, eosinopenia, low levels of total IgE, and low total IgE combined with elevated anti-thyroid peroxidase IgG. CONCLUSIONS Autoimmune CSU may be less common in patients with comorbid CIndU than without, and comorbid CIndU may point to autoallergic CSU.

Abstract
Chronic urticaria (CU) is the recurring development of wheals (aka "hives" or "welts"), angioedema, or both for more than 6 weeks. Wheals and angioedema occur with no definite triggers in chronic spontaneous urticaria, and in response to known and definite physical triggers in chronic inducible urticaria. Approximately 1.4% of individuals globally will have CU during their lifetime. The itching and physical discomfort associated with CU have a profound impact on daily activities, sexual function, work or school performance, and sleep, causing significant impairment in a patient's physical and mental quality of life. CU also places a financial burden on patients and healthcare systems. Patients should feel empowered to self-advocate to receive the best care. The voice of the patient in navigating the journey of CU diagnosis and management may improve patient-provider communication, thereby improving diagnosis and outcomes. A collaboration of patients, providers, advocacy organizations, and pharmaceutical representatives have created a patient charter to define the realistic and achievable principles of care that patients with CU should expect to receive. Principle (1): I deserve an accurate and timely diagnosis of my CU; Principle (2): I deserve access to specialty care for my CU; Principle (3): I deserve access to innovative treatments that reduce the burden of CU on my daily life; Principle (4): I deserve to be free of unnecessary treatment-related side-effects during the management of my CU; and Principle (5): I expect a holistic treatment approach to address all the components of my life impacted by CU. The stated principles may serve as a guide for healthcare providers who care for patients with CU and translate into better patient-physician communication. In addition, we urge policymakers and authors of CU treatment guidelines to consider these principles in their decision-making to ensure the goals of the patient are achievable.

Abstract
Chronic spontaneous urticaria (CSU) is a debilitating inflammatory disorder of the skin, characterized by a fluctuating natural history, a complex mechanism of action, and a significant burden on patients, including effect on quality of life, development of psychosocial disorders, and a range of comorbidities. Recent international guidelines recommend a therapeutic approach of first-line treatment with second generation H1-antihistamines and second-line treatment with the biologic omalizumab. Here, the salient aspects of CSU and current status of data for omalizumab for patients with CSU are reviewed, with a focus on mechanism of action, efficacy and real-world effectiveness (including patient outcomes, response, relapse, and remission), and safety (including consideration of the risk of anaphylaxis). The review also considers recent data on COVID-19, CSU, and omalizumab and presents our perspective on future needs. Overall, the data suggest that omalizumab is an effective and well-tolerated treatment for patients with CSU that provides benefits for a wide range of patients.

Abstract
Chronic spontaneous urticaria (CSU) is a complex skin disease characterized by the spontaneous appearance of wheals, angioedema, or both, for more than 6 weeks. Many patients experience a relapsing-remitting disease course for years. Owing to the unpredictability of wheal recurrence and the severity of pruritis, patients suffer considerable impairment in their quality of life. Physicians face multiple challenges, not least of which is a lack of clear guidance on what constitutes "treatment success". There is a lack of awareness of which measures should be used to best assess the various aspects of CSU, including disease activity, disease control, and quality of life-which themselves each comprise multiple components-and how to apply the results of each score to treatment decision-making. Although the overarching aim of treatment is for patients to be completely free of signs and symptoms of CSU, a more realistic definition of "treatment success" is needed to guide ongoing, long-term disease management for each individual patient. In this review, we consider what lessons can be learned from the current evidence base to provide further direction toward a universal definition of "treatment success".

Abstract
Chronic spontaneous urticaria (CSU) is a debilitating skin disease characterized by intensely itchy wheals, angioedema, or both. Symptoms recur spontaneously, on a near-daily basis, over >6 weeks; many patients experience flare-ups over several years and, consequently, reduced quality of life. Differences between the inflammatory profiles of the skin of CSU patients (wheals and nonlesional sites) and healthy controls indicate that key drivers such as mast cells, eosinophils, and basophils interact, release vasoactive mediators, and prime the skin, leaving patients predisposed to symptoms. Many cytokines and chemokines involved in these inflammatory networks and their corresponding intracellular signaling cascades have been identified. These insights informed the development of therapies such as omalizumab, dupilumab, and Bruton's tyrosine kinase (BTK) inhibitors, marking a renewed focus on pathogenesis in CSU clinical research. Despite progress, current therapies provide symptomatic control but do not appear to redress the inflammatory balance in the skin permanently. A deeper understanding of CSU pathogenesis will permit a more targeted approach to developing novel treatments with curative intent. Here, we review what is known about the pathogenesis of CSU and consider how this can be used to identify rational targets to improve patient care further.

Abstract
BACKGROUND Few prospective longitudinal studies have been conducted in Thailand to account for the long-term response to chronic urticaria (CU) treatment, clinical outcomes, and patient-reported outcomes (PROs) among people living with CU based on routine practice. As such, a prospective longitudinal study will be conducted to better understand the long-term responses to treatment options and the burden of disease in Thai CU patients. METHODS AND DESIGN This study is a routine clinical practice registry-based, monocentric, prospective, observational longitudinal study in the northern region of Thailand. Adult patients in an outpatient clinic diagnosed with CU, including both chronic spontaneous urticaria and chronic inducible urticaria will be recruited for this study. The cohort will be collected and registered using the joint routine clinical practice data based on multiple datasets including claims outpatient and inpatient data, routine laboratory results, medication utilization, health care costs, clinical characteristics, long-term urticaria care and monitoring, and PRO measures. The point prevalence of adverse health outcomes will be estimated and reported corresponding to 95% confidence intervals (95% CIs). The overall trend analysis will be analyzed to explore the effect of over time across the cohort time frame. CONCLUSION This prospective longitudinal study will report the clinical outcomes, PROs, and economic burden among Thai people living with CU based on routine clinical practice. Findings will provide comprehensive evidence and could facilitate best practices for CU care management for health care professionals, researchers, policymakers, and public society.

Int Immunopharmacol 2022; 112:109198.

Abstract
BACKGROUND Guidelines recommend standard doses of antihistamines as first-line, and updosing of antihistamines as second-line treatment for the management of chronic urticaria (CU). However, remission rates with different types of first- and second-line treatments and indicators of antihistamine response are largely lacking in the literature. OBJECTIVES To examine response rates to first- and second-line treatments in CU, and to identify patient characteristics that can predict antihistamine treatment outcomes. METHODS We retrospectively analyzed treatment outcomes of 657 CU (556 chronic spontaneous urticaria (CSU), 101 chronic inducible urticaria (CIndU)) patients who had at least 3-months of follow-up data. RESULTS A standard dose of second generation antihistamines (sgAH) was effective in 43.1 % of the patients. An additional 28.8 % of patients were in remission with second-line treatments. Among patients whose disease was in remission with a standard dose of sgAHs, 14.8 % benefited from switching from their current sgAH to another sgAH. Updosing sgAHs, combination of two different sgAHs, sgAH and first generation H1-antihistamine combination, and sgAH and leukotriene receptor antagonist combination provided remission in 38.3 %, 35.8 %, 37.5 % and 25 % of patients who were given these treatments, respectively. Baseline UCT score ≤ 4, emergency referral and family history of CSU were found to be risk factors for antihistamine refractoriness in patients with CSU. CONCLUSIONS A step-wise approach to the management of CU is practical as more patients respond to treatment at each step. The presence of baseline UCT score ≤ 4, emergency referral and family history of CSU might be helpful to determine patients who require third-line treatments in advance.

Abstract
Purpose Data specific to the epidemiology, clinical features, and management of chronic urticaria (CU) in the geriatric population remain limited and not well understood. We aim to systematically review the prevalence, clinical manifestations, treatment, and clinical course of elderly patients with CU. Patients and methods Original articles that included data of elderly (aged >60 years) with CU that were published until February 2021 were searched in PubMed, Scopus, and Embase using predfefined search terms. Related articles were evaluated according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. Results Among the included 85 studies and 1,112,066 elderly CU patients, most (57.4%) were women. The prevalence of elderly CU in the general population ranged from 0.2–2.8%, and from 0.7–33.3% among all CU patients. Compared to adult CU, elderly CU patients had a higher percentage of wheal alone (73.9%), and lower rate of positive autologous serum skin test and atopy. Gastrointestinal diseases were the most common comorbidity (71.9%), and there was a high rate of malignancies and autoimmune diseases. Second generation H1-antihistamines were commonly used, and achievement of complete control was most often reported. Omalizumab was prescribed in 59 refractory patients, and a significant response to treatment was reported in most patients. The treatment of comorbidities also yielded significant improvement in CU. Conclusion Elderly CU was found to be different from adult CU in both clinical and laboratory aspects. H1- antihistamines are effective as first-line therapy with minimal side-effects at licensed doses. Treatment of secondary causes is important since the elderly usually have age-related comorbidities.

Abstract
BACKGROUND Chronic spontaneous urticaria (CSU) is a common skin disease and has a significant impact on patients' quality of life. The aim of treatment is complete symptom control. AIM To identify potential factors associated with antihistamine-refractory isolated CSU and to determine the factors that predict response to second-generation H1 antihistamines at dosages from one- to fourfold. METHODS We conducted a retrospective cohort study, which included adult patients diagnosed with isolated CSU and had complete symptom control. Clinical and laboratory findings were compared between the patients who were responsive to second-generation H1 antihistamines (< fourfold) and those who were refractory to a fourfold dose. Clinical and laboratory data were compared by dosage in the antihistamine-responsive group. RESULTS There were 182 isolated CSU patients who met the study criteria, of whom 150 (82.4%) were responsive to treatment with up to a fourfold dose of second-generation H1 antihistamines, while 32 (17.6%) were refractory. In univariate analysis, age at onset, body mass index, baseline Urticaria Activity Score-7 (UAS7), white blood cell count, total neutrophil count, neutrophil-lymphocyte ratio, platelet count, and new generation antihistamines were significantly higher in the antihistamine-refractory group. According to multivariate analysis, baseline UAS7 was the only independent factor associated with antihistamine-refractory isolated CSU (odds ratio 1.14, 95% CI 1.01-1.28, P = .03). In the antihistamine-responsive group, white blood cell count tended to predict response to antihistamine treatment (P < .001, 0.04, 0.34 between onefold and twofold, twofold and threefold, and threefold and fourfold, respectively). CONCLUSION Baseline UAS7 was an independent factor associated with antihistamine-refractory isolated CSU.

Abstract
A fast skin clearance is the main goal to achieve in psoriasis treatment. Patients that present a fast and exceptional improvement with treatment are called super-responders (SR). There is no consensus on the definition of SR with respect to psoriasis. Included herein is a retrospective analysis of a multicenter, observational study of real clinical practices including patients with moderate-to-severe plaque PSO undergoing treatment with Guselkumab (GUS). This cross-sectional analysis includes information on patients between February 2019 to February 2022. A SR is a patient that achieved a PASI = 0 at weeks 12 and 24. Analyses have been performed “as observed” using GraphPad Prism version 8.3.0 for Windows (GraphPad Software, San Diego, CA, USA, At baseline, the PASI is significantly correlated with VAS_pruritus, BSA, and DLQI, while DLQI is significantly correlated with VAS_pruritus. Significant correlations increase in number and magnitude over the follow-up time. In relation to the univariate logistic models carried out, only three variables showed a significant association with the super-responder variable: depression, VAS_pruritus, and DLQI.SR patients, who show a faster evolution in PASI and BSA improvement than non-SRs. Based on the results obtained, it would be possible to also include DLQI and VAS_pruritus in the broader concept of the SR.

Abstract
Chronic spontaneous urticaria (CSU) is a debilitating mast cell-driven disease characterized by recurrent wheals and/or angioedema. Substantial progress has been made in dissecting the 2 main autoimmune mechanisms that drive the pathogenesis of CSU. Type I autoimmune (autoallergic) CSU is associated with IgE antibodies against autoantigens, for example, thyroid peroxidase and IL-24. Type IIb autoimmune CSU is mediated by autoantibodies that activate mast cells, for example, via IgE and FcεRI, and is present in less than 10% of patients with CSU when strict criteria are used, that is, triple positivity of autologous serum skin test, immunoassays for IgG autoantibodies, and basophil activation tests. A subpopulation of patients with CSU has both types. Type IIb autoimmune CSU is characterized by higher disease severity, concomitant autoimmune diseases, low levels of total IgE, elevated levels of IgG-anti-thyroid peroxidase, basopenia, eosinopenia, poor response to antihistamines and to omalizumab, and a good response to cyclosporine. Novel targeted therapies for CSU are under development such as ligelizumab, an anti-IgE, fenebrutinib and remibrutinib, Bruton's tyrosine kinase inhibitors, and dupilumab, an anti-IL-4Rα. Further studies should investigate the overlap between autoallergic and type IIb autoimmune CSU, optimize the diagnosis of both autoimmune endotypes using easy-to-perform, noninvasive, and inexpensive markers, and assess differences in response to therapy.

Correlation between Vaginal Microecological Status and Prognosis of CIN Patients with High-Risk HPV Infection. BIOMED RESEARCH INTERNATIONAL 2022; 2022:3620232. [PMID: 35463993 PMCID: PMC9023142 DOI: 10.1155/2022/3620232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Revised: 12/15/2021] [Accepted: 12/30/2021] [Indexed: 11/21/2022]
Abstract
Many microorganisms live in the vagina of healthy women. They interact with and compete with the microenvironment in the female vagina to form a dynamic balance of the microenvironment in the female vagina. However, imbalanced vaginal microecology can lead to vaginal resistance to pathogenic microorganisms. Poor capacity can cause women to develop infections of the reproductive tract. This article analyzes the vaginal microecological status of women with high-risk HPV infection for more than 6 months and healthy women and explores the risk factors that cause long-term high-risk HPV infection for timely detection and regulation of possible vaginal microecological imbalance in women with high-risk HPV infection for more than 6 months to prevent further development of cervical lesions in such patients. This article covers women with a sexual life history who attended the gynecology department of a hospital from January 2020 to September 2021. There were 280 patients in the experimental group: positive high-risk HPV; and there were 140 patients in the control group: negative high-risk HPV test. The correlation between vaginal microecology of CIN patients and patient prognosis according to the subject's vaginal microecology test results and prognosis of various levels of cervical lesions was analyzed. The experiment proved that the detection rate of normal vaginal microecology in the experimental group was 12.14% (34/280) compared with the detection rate of 29.29% (41/140) in the control group, and there was a trend of decrease, and the difference was statistically significant (χ2 = 17.23, P < 0.05). The detection rate of vaginal BV in the experimental group was 10.36% (29/280) compared with the detection rate of 5.0% (7/140) in the control group, and the difference was statistically significant (χ2 = 5.19, P < 0.05). This indicates that women with high-risk HPV infections for 6 months or longer have a higher incidence of vaginal microecological imbalances than healthy individuals and aggressive vaginal microecological screening. It is necessary to carry out the program. Detect and treat possible abnormal conditions in time to prevent the further onset of the disease.

Abstract
Background The etiopathogenesis of chronic spontaneous urticaria (CSU) has not been fully understood, and there has been extensive interest in the interaction between inflammatory dermatosis and pyroptosis. This study intends to investigate the molecular mechanism of pyroptosis-related genes in CSU via bioinformatic ways, aiming at identifying the potential key biomarker. Methods GSE72540, the RNA expression profile dataset of CSU, was utilized as the training set, and GSE57178 as the validation set. Differently expressed pyroptosis-related genes (DEPRGs), GO, KEGG, and DO analyses were performed. The hub genes were explored by the protein–protein interaction analysis. Moreover, CIBERSORT was employed for estimating immune cell types and proportions. Then, we constructed a DEmRNA–miRNA–DElncRNA ceRNA network and a drug–gene interaction network. Finally, ELISA was used for gene expression analysis. Results We recognized 17 DEPRGs, whose enrichment analyses showed that they were mostly enriched in inflammatory response and immunomodulation. Moreover, 5 hub genes (IL1B, TNF, and IRF1 are upregulated, HMGB1 and P2RX7 are downregulated) were identified via the PPI network and verified by a validation set. Then immune infiltration analysis displayed that compared with normal tissue, CSU owned a significantly higher proportion of mast cells activated, but a lower proportion of T cells CD4 naive and so on. Furthermore, IL1B was statistically and positively associated with mast cells activated in CSU, and SNHG3, the upstream factor of IL1B in the ceRNA we constructed, also related with mast cells in CSU. Further analysis exhibited that the protein subcellular localization of IL1B was extracellular, according with its intercellular regulation role; IL1B was significantly correlated with key immune checkpoints; and the NOD-like receptor signaling pathway was the mainly involved pathway of IL1B based on the couple databases. What is more, the result of ELISA of CSU patients was the same as the above analyses about IL1B. In addition, the drug–gene interaction network contained 15 potential therapeutic drugs targeting IL1B, and molecular docking might make this relationship viable. Conclusion IL1B and its related molecules might play a key role in the development of CSU and could be potential biomarkers in CSU.

Abstract
This update and revision of the international guideline for urticaria was developed following the methods recommended by Cochrane and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group. It is a joint initiative of the Dermatology Section of the European Academy of Allergology and Clinical Immunology (EAACI), the Global Allergy and Asthma European Network (GA²LEN) and its Urticaria and Angioedema Centers of Reference and Excellence (UCAREs and ACAREs), the European Dermatology Forum (EDF; EuroGuiDerm), and the Asia Pacific Association of Allergy, Asthma and Clinical Immunology with the participation of 64 delegates of 50 national and international societies and from 31 countries. The consensus conference was held on 3 December 2020. This guideline was acknowledged and accepted by the European Union of Medical Specialists (UEMS). Urticaria is a frequent, mast cell-driven disease that presents with wheals, angioedema, or both. The lifetime prevalence for acute urticaria is approximately 20%. Chronic spontaneous or inducible urticaria is disabling, impairs quality of life, and affects performance at work and school. This updated version of the international guideline for urticaria covers the definition and classification of urticaria and outlines expert-guided and evidence-based diagnostic and therapeutic approaches for the different subtypes of urticaria.

Abstract
Background Omalizumab is shown to be effective in the treatment of chronic spontaneous
urticaria (CSU), a disease with high personal and social impact. Sex
differences in CSU are recognized with women more frequently affected.
Scarce is the knowledge about response to omalizumab between sex groups. We
sought to identify any differences based on the sex of patients receiving
omalizumab. Methods We evaluated data of patients diagnosed with CSU refractory to high-dose
second-generation H1 antihistamines and treated with 300 mg omalizumab every
4 weeks for 6 months and then at relapse. Results Discussion: All patients, regardless of sex, age, or any other factor,
achieved the clinical remission of the disease after the first 3 doses with
a reduction of the disease activity indices and impact on the quality of
life. Recurrences predominate in men, two months after the suspension of the
drug. Respect to sex and recurrence we did not find any correlation with
age, body mass index, peripheral eosinophil counts, total IgE levels,
D-dimer, plasma prothrombine level or C-reactive protein. We found no sex
differences in tolerability and safety. CSU in girls may persist longer and
have worse prognosis, but no one has so far noted sex differences in
response to omalizumab. Conclusions Although there are no certainties on the mechanism of action of omalizumab in
CSU, the noticeable difference in response between males and females lead us
to suppose a role of the hormonal balance both on the pathogenesis of the
CSU and on the efficacy of OmAb.

Abstract
INTRODUCTION Chronic spontaneous urticaria (CSU) is a troublesome dermatological problem that can have a significant impact on quality of life. Previous studies have indicated that acupuncture may be beneficial for patients with CSU. However, well-designed studies determine the effects of acupuncture on CSU are rare. The aim of this study is to investigate the efficacy and safety of acupuncture treatment for patients with CSU. METHODS AND ANALYSIS This study is designed as a multicentre, parallel, three-arm, randomised, sham-controlled trial. A total of 330 patients diagnosed as CSU will be randomly allocated into three groups: the verum acupuncture group, the sham acupuncture group and the waiting-list control group in a 1:1:1 ratio. Patients in the verum and sham acupuncture groups will receive 16 treatment sessions over 4 weeks, while patients in the waiting-list control group will not receive any acupuncture treatment. The primary outcome is the changes of weekly urticaria activity scores at the end of treatment. Secondary outcomes include itching severity measurement, Dermatology Life Quality Index, Hamilton Depression Scale, Hamilton Anxiety Scale, Pittsburgh Sleep Quality Index and serum total IgE level. Adverse events will be recorded during the study observation period. All patients who are randomised in this study will be included in the intention-to-treat analysis. ETHICS AND DISSEMINATION Ethical approval of this study has been granted by the Sichuan Regional Ethics Review of Committee on Traditional Chinese Medicine (TCM) (ID: 2019 kl-006), the Medical Ethic Committee of the First Hospital of Wuhan (ID: (2019) number 7)) and the Medical Ethics Committee of the First Hospital of Hunan University of TCM (ID: HN-LLKY-2019-017-01/03) in three clinical centres in China, respectively. The results will be disseminated through peer-reviewed journals. TRIAL REGISTRATION NUMBER ChiCTR1900022994.

Abstract
Allergic and immunologic skin diseases negatively impact the quality of life (QoL) of affected patients with detrimental consequences. Nonetheless, in everyday clinical practice the evaluation of QoL is often overlooked. Considering the increasing prevalence of atopic dermatitis, allergic contact dermatitis, hereditary angioedema, cutaneous mastocytosis, and urticaria, it is essential to determine the effects of allergic and immunologic skin diseases on QoL. A joint meeting (GET TOGETHER 2021) of the Italian Society of Allergology, Asthma and Clinical Immunology (SIAAIC) and the Italian Society of Allergological, Occupational and Environmental Dermatology (SIDAPA) aimed to summarize the features of the main QoL tools used in these diseases and to describe the extent of QoL impairment as well as the impact of treatments on QoL, particularly biologic therapies. The assessment of QoL in patients with allergic and immunologic skin diseases relies on generic, organ-specific and disease-specific questionnaires. While generic and organ-specific questionnaires allow comparison between different diseases, disease-specific questionnaires are designed and validated for specific cohorts: the QoL Index for Atopic Dermatitis (QoLIAD) and the Childhood Atopic Dermatitis Impact Scale (CADIS) in atopic dermatitis, the ACD-11 in allergic contact dermatitis, the Angioedema QoL Questionnaire (AE-QoL) and the Hereditary Angioedema QoL questionnaire (HAE-QoL) in hereditary angioedema, the Mastocytosis QoL Questionnaires (MCQoL e MQLQ) in cutaneous mastocytosis, and the Chronic Urticaria QoL questionnaire (CU-Q2oL) in urticaria. Among the many factors that variably contribute to QoL impairment, pruritus can represent the leading cause of patient discomfort. Biologic therapies significantly ameliorate QoL in atopic dermatitis, hereditary angioedema, mastocytosis and chronic urticaria. In general, adequate management strategies are essential for improving QoL in patients with allergic and immunologic skin diseases.

Abstract
BACKGROUND Comprehensive data on the epidemiology and comorbidities of chronic urticaria (CU) in Germany are either limited, or not contemporary. OBJECTIVES To investigate the epidemiology of CU, overall comorbidities and healthcare resource utilized by patients with CU in Germany, using an anonymized statutory health insurance (SHI) database. METHODS Anonymized SHI claims research database of the Institute for Applied Health Research, Berlin [InGef] (01 January 2015-30 September 2018) was used to analyse insured individuals with a confirmed diagnosis of CU (ICD-10-GM codes). Twelve-month diagnosed prevalence and incidence, comorbidities (vs. atopic dermatitis and psoriasis), and healthcare utilization by patients with CU were investigated. RESULTS Of 4 693 772 individuals of all ages listed in the database, 3 538 540 were observable during 2017. Overall, 17 524 patients (˜0.5%) were diagnosed with CU; chronic spontaneous urticaria (CSU: 71.2%), chronic inducible urticaria (CIndU: 19.7%), CSU+CIndU (9.1%). Females, vs. males, had higher diagnosed prevalence (0.62% vs. 0.37%) and diagnosed incidence (0.18% vs. 0.11%) of CU among all patients. Patients most frequently visited general practitioners (41.3% of total visits). Hypertensive diseases (43.5%), lipoprotein metabolism disorders (32.1%) and affective disorders (26.0%) were the most frequently reported comorbidities of special interest. Rates of most comorbidities of special interests were similar to atopic dermatitis and psoriasis patients, and all higher vs. overall population. More than half (54.1%) of all CU patients were not prescribed any treatment. Second-generation H1 -antihistamines were the most commonly prescribed medication for adult (17.9%) and paediatric (27.9%) patients. Patients with CIndU (paediatric, 15.5%; adult, 7.8%) were more often hospitalized versus patients with CSU (paediatric, 9.9%; adult, 4.6%). CONCLUSIONS In Germany, prevalence of CU along with multiple comorbidities may pose increased burden on the healthcare system. Awareness of adhering to treatment guidelines, and aiming for complete control of urticaria, needs to be driven and may improve outcomes.

Abstract
The current therapeutic algorithm for chronic spontaneous urticaria (CSU), endorsed by the international guideline, entails treatment escalation from second-generation H1 -antihistamines (sgAHs) to omalizumab and cyclosporine until complete response is achieved. Recently, several predictors of response to these treatment options have been described. Here, we discuss the most promising predictors of response and nonresponse to these treatments in CSU. A systematic search was performed by two independent researchers using the MEDLINE/PubMed database with specific keywords and 73 studies included in the review. Levels of evidence were categorized as strong (robust predictors), weak (emerging predictors) or no association, based on the outcome and number of studies available. High disease activity, high levels of C-reactive protein and D-dimer are robust predictors for a poor or no response to sgAHs. Poor or no response to omalizumab is robustly predicted by low serum levels of total IgE. A good response to cyclosporine is robustly predicted by a positive basophil histamine release assay, whereas low total IgE is an emerging predictor. The response to treatment with sgAHs, omalizumab and cyclosporine can be predicted by the use of markers that are readily available in routine clinical practice. Further studies are needed to confirm these predictors.

Abstract
Chronic urticaria (CU) is a common skin condition characterized by the recurrence of wheals, with or without angioedema, which lasts for at least 6 weeks. Owing to its pruritus and incurability, this disease adversely affects the patients' physical and mental health and diminishes the quality of life. CU is generally classified into two subtypes based on the relevance of eliciting factors: chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU), the latter of which is further divided into several subtypes. To improve the understanding and clinical management of this highly heterogeneous disorder, the EAACI/GA2LEN/EDF/WAO guideline was developed and published in 2018 based on evidence and expert consensus. The diagnostic and treatment algorithms proposed by the guideline have largely facilitated dermatologists in clinical practice. However, several questions remained unsolved and have been widely investigated in the recent years. First, a better understanding of the association between chronic urticaria and its potential underlying causes or eliciting factors such as autoimmunity, infections, coagulation aberrance, and vitamin D deficiency is warranted. This would lead to updates in the diagnostic and treatment procedures of different subtypes of chronic urticaria. Secondly, treatment for recalcitrant cases, especially those resistant to or intolerant of second-generation antihistamines and (or) omalizumab, calls for novel therapeutic measures or strategies. In the present review, we summarized recent advances in the understanding and management of both CSU and CIndU, with special emphasis on their underlying causes or eliciting factors, pathogenic mechanisms, potential targets for intervention, and advances in treatment strategies.

Abstract
Chronic spontaneous urticaria (CSU) is characterized by the presence of wheals, angioedema, or both for at least 6 weeks. It may persist for a long time-up to 50% of the patients have been reported to be symptomatic 5 years after the onset. Some patients can suffer more than one episode of CSU during their lifetime. Considering the recurrences, disabling symptoms, and significant impact on quality of life, proper and effective treatment of CSU is critical. The use of antihistamines (AHs) is still the mainstay of treatment. However, given the low rates of response to AHs (38.6% and 63.2% to standard doses and higher doses, respectively), the complete control of symptoms seems difficult to attain. The use of omalizumab for CSU has been a major breakthrough in the care of patients with CSU. However, the partial response and lack of response to omalizumab in a subgroup of patients, as high as 70% in some studies, make the development of alternative treatments desirable. Ever-increasing knowledge on the pathogenesis is making new target molecules available and enabling drug development for CSU. In addition to drug repurposing as in anti-IL-4/13, IL-5, and IL-17 antibodies, novel targeted therapy options such as ligelizumab and Bruton's tyrosine kinase inhibitors are currently undergoing clinical trials and will be available in the near future. This article reviews the current challenges in the treatment of CSU, the pathogenesis and potential target molecules, and the rationale for novel treatments and their rapidly developing status.

Abstract
BACKGROUND There are few epidemiological studies of urticaria, published in the indexed literature (PubMed/Medline). OBJECTIVE The study aimed to evaluate the epidemiological and clinical data among patients with urticaria/angioedema attending a reference clinic in Brazil. METHODS Two hundred sixty-seven patients were evaluated retrospectively considering demographic data, time course of the disease, triggering symptoms, the presence of angioedema, complementary laboratory tests including total blood count, reactive-C protein, erythrocyte sedimentation rate, IgE serum levels, and other, as necessary. RESULTS The most commonly diagnosed type of urticaria was chronic spontaneous urticaria (56.93%). Angioedema was associated with chronic urticaria in 108 patients (40.08%). STUDY LIMITATIONS Unicentered and retrospective. CONCLUSION Some relevant findings in this study are the observation of a female prevalence of cases (4-females: 1-man), a result more elevated than demonstrated in previous studies in Europe and Asia, the median age was 43-years old and the delay of time between the diagnosis of urticaria and the admission for treatment in a specialized center was approximately 2-years. Other multicenter studies can better establish these differences in Brazilian patients.

Abstract
BACKGROUND In chronic spontaneous urticaria (CSU), the guidelines recommend very limited diagnostic procedures during the routine workup, although additional investigations might be indicated in some patients with CSU. For physicians treating patients with CSU, it is often difficult to decide which diagnostic tests are useful. OBJECTIVE To provide recommendations on what diagnostic tests should be performed on which patients with CSU. METHODS We performed an extensive literature search on the respective topics and identified relevant questions that should prompt diagnostic procedures based on the published evidence and expert consensus among all authors. RESULTS We provide questions, diagnostic testing, where appropriate, and recommendation that should be included when assessing the history of a patient with CSU, to explore and rule out differential diagnoses, to assess patients for underlying causes and modifying conditions, to explore patients for comorbid diseases and consequences of having CSU, and to assess patients for CSU components that can help to predict their disease course and response to treatment. CONCLUSIONS Here, we provide physicians treating patients with CSU with information about which clues should lead to which tests and why.

It is never too late to treat chronic spontaneous urticaria with omalizumab: Real-life data from a multicenter observational study focusing on elderly patients. Dermatol Ther 2021; 34:e14841. [PMID: 33527659 DOI: 10.1111/dth.14841] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Revised: 01/09/2021] [Accepted: 01/20/2021] [Indexed: 01/15/2023]
Abstract
Chronic spontaneous urticaria might affect elderly patients, causing a serious impairment of their quality of life. The therapeutic management of the elderly patient is challenging; in fact, the first-line recommended therapy for symptom control are antihistamines, that may have interactions or increased risk of side effects in patients with comorbidities and poly-pharmacological regimen. Omalizumab is the first biological drug approved for chronic spontaneous urticaria resistant to antihistamines. Real-life data focusing on patients >65-year-old treated with omalizumab are rare. In our retrospective study, we evaluated the efficacy and safety of this biologic therapy in patients over 65-year-old. We performed Urticaria Activity Score-7 (UAS-7) in order to evaluate the efficacy of omalizumab and the time of remission. We collected any adverse event related to the treatment. Moreover, we investigated the presence of comorbidities and their impact on the efficacy of omalizumab. Sixty-threepatients, with a mean age of 72.3 ± 5.6 years, range: 65-89) were enrolled. Of 63 subjects, 23 (36.5%) had an "early complete response" profile, which means the achievement of a UAS7 score of "0" within the first 7 days of therapy. The most frequent comorbidity was hypertension, which affected 26 of 63 (41.3%) patients; no adverse events were reported. No significant correlations were found between treatment effectiveness and comorbidities. Omalizumab is a safe and effective therapy also in elderly patients with multiple comorbidities.

Abstract
Introduction: Chronic spontaneous urticaria (CSU) is a frequent disorder in which activation of effector cells and histamine release can be induced via several distinct pathogenetic mechanisms. Much work has been carried out to identify biomarkers useful for classifying CSU patients, and to predict their response to currently available treatments.Areas covered: The recent literature dealing with CSU biomarkers was screened in PubMed and Google Scholar using 'chronic spontaneous urticaria', 'biomarker', 'diagnosis', 'therapy' and 'treatment response' as key words. The characteristics found in relevant papers were divided into clinical and serological biomarkers of (a) clinical severity/disease activity, and (b) response to treatments.Expert opinion: A diagnostic biomarker for CSU is still missing. Most biomarkers described so far do not seem to possess sufficient specificity for this disease. Basopenia and the activation of the coagulation cascade might be biomarkers of disease activity and severity, but information available so far is insufficient to consider their routine use. Markers suggesting IgG-mediated autoimmunity (autologous serum skin test, basophil activation/histamine release assays, low total IgE) seem to identify patients less prone to respond to omalizumab but responsive to cyclosporine. In contrast, 'autoallergy' (i.e. the presence of IgE to autoallergens), which is often associated with elevated IgE levels seems to identify patients who will respond to omalizumab.

Evaluation of serum levels of C-reactive protein, D-Dimer and Autologous Serum Skin Test in patients with Chronic Spontaneous Urticaria in a Brazilian tertiary center : a cross-sectional study. An Bras Dermatol 2021; 96:148-154. [PMID: 33640190 PMCID: PMC8007487 DOI: 10.1016/j.abd.2020.07.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2020] [Accepted: 07/20/2020] [Indexed: 12/03/2022] Open
Abstract
Background The pathophysiology of urticaria is still poorly understood. Recent studies demonstrate that the activation of coagulation is correlated with the clinical activity of Chronic Spontaneous Urticaria. Coagulation and inflammation are strongly linked. Objectives To correlate the severity and activity of Chronic Spontaneous Urticaria with the levels of D-dimer, C-reactive protein, and autologous serum test in patients with Chronic Spontaneous Urticaria. Methods The study included 55 patients diagnosed with chronic spontaneous urticaria. D-dimer levels were measured using enzyme-linked fluorescent assay and C-reactive protein levels were measured using the nephelometric method; autologous serum testing was performed on patients who discontinued antihistamine therapy. The severity of the disease was assessed using the urticaria activity score. Results patients with severe, spontaneous, and difficult-to-control chronic urticaria had elevated serum levels of D-dimer, as well as a positive autologous serum test. Little correlation was demonstrated between the severity of chronic spontaneous urticaria and the levels of C-reactive protein. Conclusion The authors concluded that patients with severe Chronic Spontaneous Urticaria showed signs of activated fibrinolysis. Most patients with high clinical scores had high D-dimer values. Patients with positive results for the autologous serum test also had more severe Chronic Spontaneous Urticaria and needed more drugs to control the disease. Finally, little correlation was found between C-reactive protein levels and disease severity. Study limitations The main limitation was the small sample of patients. In the present patients, it was demonstrated that serum D-dimer levels and the autologous serum test can act as predictive markers of severity and activity of Chronic Spontaneous Urticaria.

Abstract
In a previous study, we found that higher waist circumference (WC) and higher body mass index (BMI) both increase the risk of chronic spontaneous urticaria (CSU). The aim of this study was to determine whether WC and BMI also increase the duration of CSU. We used multivariable Cox proportional hazards models to determine the hazard ratio (HR) for longer disease duration (longer than 3 years) according to WC and BMI. A total of 52,667 subjects were enrolled and their mean age was 54.5. After adjustments for other confounding variables the high WC/high BMI group had 1.062 times higher HR (95% CI, 1.028-1.098) than the normal WC/normal BMI group. Interestingly, the high WC/normal BMI group showed a significantly higher HR (1.053; 95% CI, 1.008-1.101) than the normal WC/normal BMI group, but not the normal WC/high BMI group (0.998; 95% CI, 0.951-1.046). Taken together, our results suggest that high WC rather than high BMI is a predictive risk factor for the longer disease duration of CSU.

Abstract
Background A Worldwide Antihistamine-Refractory Chronic Urticaria (CU) patient Evaluation (AWARE) is a non-interventional, multicenter study including patients from Europe, Central and Latin America, Asia-Pacific, and the Middle East. AWARE describes real-world evidence for CU, including clinical characteristics, treatment patterns and the impact on quality of life. Methods Over the 2-year study, therapy changes, angioedema occurrence, and patient-reported outcomes (PROs) were recorded over 9 visits, including dermatology life quality index (DLQI) and 7-day urticaria activity score (UAS7). Data were stratified into subgroups: chronic spontaneous urticaria (CSU), chronic inducible urticaria (CIndU), or CSU + CIndU. Results Out of 4838 patients analyzed, 9.9% were receiving no treatment for their CU symptoms at baseline, and 20.4% were receiving first-line non-sedating H1-antihistamine at approved doses. The predominant baseline therapy was up-dosed non-sedating H1-antihistamines (25.5%). By Visit 2, omalizumab was the overall most commonly used therapy (29.6%), increasing to 30.1% by the end of the study. Baseline DLQI scores for patients with CSU, CIndU and CSU + CIndU were 8.3, 7.6 and 9.1, respectively; scores decreased over the study for CSU and CSU + CIndU patients, but fluctuated for CIndU patients. Baseline angioedema occurrence was higher in CSU and CSU + CIndU patients, reported in 45.4% and 45.5% of patients, respectively, compared to 17.0% in CIndU patients. By the final visit, angioedema had decreased to 11.9% and 11.2% for CSU and CSU + CIndU, respectively, and 9.6% for CIndU. Conclusion CU patients are undertreated at baseline; after entering the AWARE study, more patients received appropriate treatment. However, over two thirds are not escalated to third-line treatments.

Abstract
Objective To evaluate the positivity of challenge tests of patients suspected of chronic inducible urticaria and the response to treatment. Methods A retrospective study of electronic medical records of patients suspected of chronic inducible urticaria. All patients were submitted to challenge tests with triggering stimuli, according to the clinical history and, subsequently, the response to drug treatment was evaluated. Results A total of 191 patients with suspected chronic inducible urticaria were included. It was confirmed in 118 patients and 122 positive tests (4 patients with 2 different positive tests). Most had dermographic urticaria (70.3%), followed by cholinergic urticaria (17.8%). Regarding treatment, 28% responded to antihistamine in licensed doses, 34.7% with increased doses, 9.3% responded to the addition of another medication. The concomitance of chronic inducible urticaria and chronic spontaneous urticaria was found in 35.3% of patients, being more frequent in females, with longer time to control symptoms and higher frequency of cholinergic urticaria. Conclusion The confirmation of chronic inducible urticaria in patients with this suspicion, after challenge tests, was high. There was a good response to antihistamine. In the concomitance of chronic spontaneous urticaria, longer time to control symptoms and higher frequency of cholinergic urticaria were observed.

Abstract
Background Chronic urticaria (CU) is a condition characterized by recurrent itchy hives and/or angioedema for ≥6 weeks. Most of the data about CU come from western countries with very little information available about CU in Asia, Africa, and the Middle East. Methods AWARE-AMAC is a 24-month prospective, observational, real-world, non-interventional study in patients aged ≥18 years from Asia, the Middle East, and Africa (AMAC) with CU refractory to H1-antihistamines (H1-AH). The main objective was to describe the real-world experience with CU, including clinical characteristics, presence of angioedema, treatment patterns (shifts between treatment classes and changes within a treatment class), investigator-assessed disease control, and the impact on quality of life. Subgroups of interest were type of CU at Baseline and treatment class (based on 2013 urticaria guidelines). There were no mandatory visits and diagnostic/monitoring procedures additional to routine practice, except the patient diary (7-day Urticaria Activity Score) and patient reported outcome assessments. Results The focus of the current manuscript is on patients with chronic spontaneous urticaria (CSU), who formed 98% of the sample. Patients were predominantly female (69.6% female, mean age ± SD 39.8 ± 13.29 years). Time since current diagnosis (Mean ± SD) was 28.6 ± 49.06 months. Amongst patients with CSU, 31.0% had comorbid chronic inducible urticaria (CINDU) and 46.4% had a history of angioedema. 91.9% received H1-AH therapy (±other treatments). The most frequently prescribed treatment classes at Baseline were any/combination of medications, not classified under the other 7 treatment classes, named “Others” (30.5%) followed by, omalizumab (OMA; 23.6%) and second-generation H1-AH monotherapy (sgAH; 15.1%). At Month 12, the most prescribed treatment classes (>15%) for patients were OMA (23.5%) and "Other" (21.3%); 19.7% received "No drug". At Month 24, OMA (22.5%), and "Other" (17.9%) were most frequently prescribed; 28.6% received "No drug". Overall, 79.5% of patients had some type of change in treatment. Over the study period, improvement in self-reported QoL increased, which was mirrored by better disease control. Conclusion In AMAC countries, the non-recommended "Other" treatment class played a major role in the initial management of CU patients. High usage of H1-AH (±other treatments) and OMA was observed. Treatment changes were observed in a majority of patients. Treatment escalation from sgAH was mostly via OMA. Improvement of disease control and QoL was achieved during the study period. Trial registration Observational study (NA).

Abstract
Background: Up to 1% of the general population in the USA and Europe suffer from chronic urticaria (CU) at some point in their lifetime. CU has an adverse effect on the quality of life. Objective: This study aims to provide an update on the epidemiology, pathogenesis, clinical manifesta-tions, diagnosis, aggravating factors, complications, treatment and prognosis of CU. Methods: The search strategy included meta-analyses, randomized controlled trials, clinical trials, reviews and pertinent references. Patents were searched using the key term “chronic urticaria” at the following links: www.google.com/patents, www.uspto.gov, and www.freepatentsonline.com. Results: CU is a clinical diagnosis, based on the episodic appearance of characteristic urticarial lesions that wax and wane rapidly, with or without angioedema, on most days of the week, for a period of six weeks or longer. Triggers such as medications, physical stimuli, and stress can be identified in 10 to 20% of cases. C-reactive protein/erythrocyte sedimentation rate, and complete blood cell count with differential are the screening tests that may be used to rule out an underlying disorder. The mainstay of therapy is reassurance, patient education, avoidance of known triggers, and pharmacotherapy. Second-generation H1 antihistamines are the drugs of choice for initial therapy because of their safety and efficacy profile. If satisfactory improvement does not occur after 2 to 4 weeks or earlier if the symptoms are intolerable, the dose of second-generation H1 antihistamines can be increased up to fourfold the manufacturer’s recom-mended dose (all be it off license). If satisfactory improvement does not occur after 2 to 4 weeks or earlier if the symptoms are intolerable after the fourfold increase in the dosage of second-generation H1 antihis-tamines, omalizumab should be added. If satisfactory improvement does not occur after 6 months or earli-er if the symptoms are intolerable after omalizumab has been added, treatment with cyclosporine and sec-ond-generation H1 antihistamines is recommended. Short-term use of systemic corticosteroids may be considered for acute exacerbation of CU and in refractory cases. Recent patents for the management of chronic urticaria are also discussed. Complications of CU may include skin excoriations, adverse effect on quality of life, anxiety, depression, and considerable humanistic and economic impacts. On average, the duration of CU is around two to five years. Disease severity has an association with disease duration. Conclusion: CU is idiopathic in the majority of cases. On average, the duration of CU is around two to five years. Treatment is primarily symptomatic with second generation antihistamines being the first line. Omalizumab has been a remarkable advancement in the management of CU and improves the quality of life beyond symptom control.

Abstract
Background Urticarias are frequent diseases, with 15% to 20% of the population
presenting at least one acute episode in their lifetime. Urticaria are
classified in acute ( ≤ 6 weeks) or chronic (> 6 weeks). They may
be induced or spontaneous. Objectives To verify the diagnostic and therapeutic recommendations in chronic
spontaneous urticaria (CSU), according to the experience of Brazilian
experts, regarding the available guidelines (international and US). Methods A questionnaire was sent to Brazilian experts, with questions concerning
diagnostic and therapeutic recommendations for CSU in adults. Results Sixteen Brazilian experts answered the questionnaire related to diagnosis and
therapy of CSU in adults and data were analyzed. Final text was written,
considering the available guidelines (International and US), adapted to the
medical practices in Brazil. Diagnostic work up in CSU is rarely necessary.
Biopsy of skin lesion and histopathology may be indicated to rule out other
diseases, such as, urticarial vasculitis. Other laboratory tests, such as
complete blood count, CRP, ESR and thyroid screening. Treatment of CSU
includes second-generation anti-histamines (sgAH) at licensed doses, sgAH
two, three to fourfold doses (non-licensed) and omalizumab. Other drugs,
such as, cyclosporine, immunomodulatory drugs and immunosuppressants may be
indicated (non-licensed and with limited scientific evidence). Conclusions Most of the Brazilian experts in this study partially agreed with the
diagnostic and therapeutic recommendations of the International and US
guidelines. They agreed with the use of sgAH at licensed doses. Increase in
the dose to fourfold of sgAH may be suggested with restrictions, due to its
non-licensed dose. Sedating anti-histamines, as suggested by the US
guideline, are indicated by some of the Brazilian experts, due to its
availability. Adaptations are mandatory in the treatment of CSU, due to
scarce or lack of other therapeutic resources in the public health system in
Brazil, such as omalizumab or cyclosporine.

Abstract
The second-generation H1-antihistamines (sgAH) are the first-line symptomatic treatment of patients with chronic spontaneous urticaria (CSU). Up to 50% of the patients will not respond to licensed doses of sgAH. According to the guidelines, the dose of sgAH may be increased up to 4 times the conventional dose. However, even at higher doses, there is a subgroup of patients refractory to the antihistamine treatment. The purpose of this article was to review the different treatment options of antihistamine-refractory CSU patients. This revision examines the available literature for therapies used in chronic urticaria, including omalizumab, ciclosporin A, oral glucocorticoids, leukotriene receptor antagonists, H2 antihistamines, doxepin, dapsone, hydroxychloroquine, phototherapy, methotrexate, mycophenolate mofetil, azathioprine, autohemotherapy, intravenous immunoglobulins and rituximab, between others. After the exhaustive review of the medical literature only few high-quality studies have been identified, mostly for omalizumab. Omalizumab is an anti-immunoglobulin E monoclonal antibody, approved for the treatment of CSU, that has radically changed the management of the patients without good response to sgAH, allowing to reach complete responses in a high percentage of patients. Although actually the therapeutic management of CSU is more effective and safer than before 2014, there is place even for new and more effective treatments. A good number of partial responders and slow responders to omalizumab and a little percentage still of non-responders to available therapies stimulate the development of new drugs that will also be discussed.

Abstract
Background Global chronic urticaria (CU) disease experience and management is not well documented. This study descriptively compares these aspects among CU patients residing in Europe (EU) and Central and South America (C/SA). Methods AWARE (A World-wide Antihistamine-Refractory chronic urticaria patient Evaluation) is a global prospective, non-interventional study of CU in the real-world setting. Patients were ≥ 18 years with a diagnosis of H1-antihistamine-refractory CU for > 2 months. Differences between the EU and C/SA regions in demographic and clinical characteristics, quality of life (QoL), work and activity impairment, pharmacological treatment, and healthcare resource use were examined. Results In total, 4224 patients were included in the analysis (C/SA 492; EU 3732). Rates of untreated patients were greater in the C/SA region (45.1% vs. 31.9%; P < 0.005) and escalation to third-line therapy was rare in both regions. Differences in disease experience emerged, with C/SA patients more commonly experiencing angioedema (C/SA 50.8% vs. EU 46.1%; P = 0.03) or comorbid chronic inducible urticaria (C/SA 30% vs. EU 22%; P < 0.001). Correspondingly, rates of uncontrolled urticaria were higher among C/SA patients (82.8% vs. 77.5%; P = 0.017) and patients in the C/SA region showed significantly greater work and activity impairment (absenteeism: 10.4 ± 19.7 vs. 6.7 ± 19.0, P = 0.004; presenteeism: 30.3 ± 31.9 vs. 24.4 ± 25.8, P = 0.001; work productivity loss: 33.9 ± 33.9 vs. 26.5 ± 27.5, P < 0.001; activity impairment: 37.7 ± 34.7 vs. 32.7 ± 30.1, P = 0.001). However, QoL impairment was greater in the EU region (Dermatology Life Quality Index: C/SA 6.5 ± 5.9 vs. EU 8.3 ± 7.0; P < 0.001). There was a significant difference in use of healthcare resources, including emergency services (39.6% vs. 29.3%; P < 0.001), hospitalization (7.7% vs 21.9%; P < 0.001) general practitioners (31.7% vs 57.3%; P < 0.001), and additional allergists or dermatologists (50.6% vs. 47.3%, P < 0.001), among patients in the C/SA and EU region, respectively. In both regions, patients with a primary diagnosis of CU with angioedema had significantly greater impairment in work and non-work activities and healthcare resource utilization compared to those without angioedema. Conclusions This study revealed that CU is a heterogeneous condition with differences in healthcare utilization and outcomes between EU and C/SA. However, overall there is a high unmet need of H1-antihistamine-refractory CU patients, which is associated with high use of healthcare resources, and has a large negative effect on QoL and work productivity.
