Abstract: This evidence‐ and consensus‐based guideline was developed following the methods recommended by Cochrane and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group. The conference was held on 1 December 2016. It is a joint initiative of the Dermatology Section of the European Academy of Allergology and Clinical Immunology (EAACI), the EU‐founded network of excellence, the Global Allergy and Asthma European Network (GA²LEN), the European Dermatology Forum (EDF) and the World Allergy Organization (WAO) with the participation of 48 delegates of 42 national and international societies. This guideline was acknowledged and accepted by the European Union of Medical Specialists (UEMS). Urticaria is a frequent, mast cell‐driven disease, presenting with wheals, angioedema, or both. The lifetime prevalence for acute urticaria is approximately 20%. Chronic spontaneous urticaria and other chronic forms of urticaria are disabling, impair quality of life and affect performance at work and school. This guideline covers the definition and classification of urticaria, taking into account the recent progress in identifying its causes, eliciting factors and pathomechanisms. In addition, it outlines evidence‐based diagnostic and therapeutic approaches for the different subtypes of urticaria. [ABSTRACT FROM AUTHOR]

Background GA² LEN, the Global Allergy and Asthma European Network, has recently launched a program for the development, interaction, and accreditation of centers of reference and excellence in special areas of allergy embedded in its overall quality management of allergy centers of excellence. The first area chosen is urticaria. Urticaria is a common and debilitating condition and can be a challenge for both patients and treating physicians, especially when chronic. Centers of reference and excellence in urticaria ( UCAREs) can help to improve the management of hard-to-treat conditions such as urticaria. Aims Here, we describe the aims, the requirements and deliverables, the application process, and the audit and accreditation protocol for GA² LEN UCAREs. Results The main aims of GA² LEN UCAREs are to provide excellence in urticaria management, to increase the knowledge of urticaria by research and education, and to promote the awareness of urticaria by advocacy activities. To become a certified GA² LEN UCARE, urticaria centers have to apply and fulfill 32 requirements, defined by specific deliverables that are assessed during an audit visit. Discussion and Conclusion The GA² LEN UCARE program will result in a strong network of urticaria specialists, promote urticaria research, and harmonize and improve urticaria management globally.

This guideline is the result of a systematic literature review using the ' Grading of Recommendations Assessment, Development and Evaluation' ( GRADE) methodology and a structured consensus conference held on 28 and 29 November 2012, in Berlin. It is a joint initiative of the Dermatology Section of the European Academy of Allergy and Clinical Immunology ( EAACI), the EU-funded network of excellence, the Global Allergy and Asthma European Network ( GA2 LEN), the European Dermatology Forum ( EDF), and the World Allergy Organization ( WAO) with the participation of delegates of 21 national and international societies. Urticaria is a frequent, mast cell-driven disease, presenting with wheals, angioedema, or both. The life-time prevalence for acute urticaria is approximately 20%. Chronic spontaneous urticaria and other chronic forms of urticaria do not only cause a decrease in quality of life, but also affect performance at work and school and, as such, are members of the group of severe allergic diseases. This guideline covers the definition and classification of urticaria, taking into account the recent progress in identifying its causes, eliciting factors and pathomechanisms. In addition, it outlines evidence-based diagnostic and therapeutic approaches for the different subtypes of urticaria. This guideline was acknowledged and accepted by the European Union of Medical Specialists ( UEMS). [ABSTRACT FROM AUTHOR]

The aim of this Global Allergy and Asthma European Network (GA2LEN) consensus report is to provide recommendations and suggestions for assessing patient-reported outcomes (PROs) including health-related quality of life in patients with urticaria. We recommend that PROs should be used both in clinical trials and routine practice for the evaluation of urticaria patients. We suggest that PROs should be considered as the primary outcome of future clinical trials. Two validated and disease-specific instruments for assessing PROs are available, the urticaria activity score (for symptoms) and the chronic urticaria questionnaire on quality of life CU-Q2oL. This latter tool, CU-Q2oL, is available in many languages and should be preferred, where available, over more generic instruments for assessing urticaria-specific effects on quality of life. CU-Q2oL is only suited for the investigation of patients with chronic spontaneous urticaria. Similar instruments for other forms of urticaria have yet to be developed and validated. Also, tools for assessing other chronic spontaneous urticaria PROs besides quality of life and symptoms are needed. [ABSTRACT FROM AUTHOR]

Chronic spontaneous urticaria, formerly also known as chronic idiopathic urticaria and chronic urticaria (CU), is more common than previously thought. At any time, 0.5-1% of the population suffers from the disease (point prevalence). Although all age groups can be affected, the peak incidence is seen between 20 and 40 years of age. The duration of the disease is generally 1-5 years but is likely to be longer in more severe cases, cases with concurrent angioedema, in combination with physical urticaria or with a positive autologous serum skin test (autoreactivity). Chronic spontaneous urticaria has major detrimental effects on quality of life, with sleep deprivation and psychiatric comorbidity being frequent. It also has a large impact on society in terms of direct and indirect health care costs as well as reduced performance at work and in private life. In the majority of patients, an underlying cause cannot be identified making a causal and/or curative treatment difficult. Nonsedating H1-antihistamines are the mainstay of symptomatic therapy, but treatment with licensed doses relieves symptoms effectively in <50% of patients. Although guideline-recommended updosing up to fourfold increases symptom control in many patients, a substantial number of patients have only little benefit from H1-antihistamines. Consequently, there is a great need for new therapeutic strategies. [ABSTRACT FROM AUTHOR]

Background: Although chronic urticaria (CU) is a common and primarily affects females, there is little data on how pregnancy interacts with the disease., Objective: To analyse the treatment use by CU patients before, during and after pregnancy as well as outcomes of pregnancy., Methods: PREG-CU is an international, multicentre study of the Urticaria Centers of Reference and Excellence network. Data were collected via a 47-item-questionnaire completed by CU patients who became pregnant during their disease course., Results: Questionnaires from 288 CU patients from 13 countries were analysed. During pregnancy, most patients (60%) used urticaria medication including standard-dose second generation H1-antihistamines (35.1%), first generation H1-antihistamines (7.6%), high-dose second-generation H1-antihistamines (5.6%) and omalizumab (5.6%). The preterm birth rate was 10.2%; rates were similar between patients who did and did not receive treatment during pregnancy (11.6% vs. 8.7%, respectively). Emergency referrals for CU and twin birth were risk factors for preterm birth. The caesarean delivery rate was 51.3%. More than 90% of new-borns were healthy at birth. There was no link between any patient or disease characteristics or treatments and medical problems at birth., Conclusion: Most CU patients used treatment during pregnancy especially second-generation antihistamines which seem to be safe during pregnancy regardless of the trimester. The rates of preterm births and medical problems of new-borns in CU patients were similar to population norms and not linked to treatment used during pregnancy. Emergency referrals for CU increased the risk of preterm birth and emphasize the importance of sufficient treatment to keep urticaria under control during pregnancy., (© 2022 The Authors.

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., (© 2021 GA²LEN.

Background: Chronic urticaria (CU) predominantly affects women, and sex hormones can modulate disease activity in female CU patients. As of now, the impact of pregnancy on CU is largely unknown., Aim: To analyze the course and features of CU during and after pregnancy., Patients and Methods: PREG-CU is an international, multicenter study of the Urticaria Centers of Reference and Excellence (UCARE) network. Data were collected via a 47-item questionnaire completed by CU patients, who became pregnant within the last 3 years., Results: A total of 288 pregnancies of 288 CU patients from 13 countries were analyzed (mean age at pregnancy: 32.1 ± 6.1 years, duration of CU: 84.9 ± 74.5 months; CSU 66.9%, CSU + CIndU 20.3%, CIndU 12.8%).During pregnancy, 51.1% of patients rated their CU as improved, 28.9% as worse, and 20.0% as unchanged.CU exacerbations most commonly occurred exclusively during the third trimester (in 34 of 124 patients; 27.6%) or the first (28 of 124; 22.8%). The risk factors for worsening of CU during pregnancy were having mild disease and no angioedema before pregnancy, not taking treatment before pregnancy, CIndU, CU worsening during a previous pregnancy, treatment during pregnancy, and stress as a driver of exacerbations. After giving birth, urticaria disease activity remained unchanged in 43.8% of CU patients, whereas 37.4% and 18.1% experienced worsening and improvement, respectively., Conclusions: These results demonstrate the complex impact of pregnancy on the course of CU and help to better counsel patients who want to become pregnant and to manage CU during pregnancy., (© 2021 European Academy of Allergy and Clinical Immunology and John Wiley & Sons Ltd.)

Introduction: The COVID-19 pandemic dramatically disrupts health care around the globe. The impact of the pandemic on chronic urticaria (CU) and its management are largely unknown., Aim: To understand how CU patients are affected by the COVID-19 pandemic; how specialists alter CU patient management; and the course of CU in patients with COVID-19., Materials and Methods: Our cross-sectional, international, questionnaire-based, multicenter UCARE COVID-CU study assessed the impact of the pandemic on patient consultations, remote treatment, changes in medications, and clinical consequences., Results: The COVID-19 pandemic severely impairs CU patient care, with less than 50% of the weekly numbers of patients treated as compared to before the pandemic. Reduced patient referrals and clinic hours were the major reasons. Almost half of responding UCARE physicians were involved in COVID-19 patient care, which negatively impacted on the care of urticaria patients. The rate of face-to-face consultations decreased by 62%, from 90% to less than half, whereas the rate of remote consultations increased by more than 600%, from one in 10 to more than two thirds. Cyclosporine and systemic corticosteroids, but not antihistamines or omalizumab, are used less during the pandemic. CU does not affect the course of COVID-19, but COVID-19 results in CU exacerbation in one of three patients, with higher rates in patients with severe COVID-19., Conclusions: The COVID-19 pandemic brings major changes and challenges for CU patients and their physicians. The long-term consequences of these changes, especially the increased use of remote consultations, require careful evaluation., (© 2020 The Authors.

Vitiligo is common acquired pigmentary disorder affecting skin of 1% of the world population, India 3% to 8% incidences approximately. Treatment is tough challenge. The combination treatments have proven beneficial due to different mechanisms. There is need to find drug targeting different mechanisms of action. Test medicine is decapeptide derived from basic Fibroblast Growth Factor (bFGF) treating vitiligo. The current study was to compare efficacy and safety of BFGF related decapeptide solution plus Tacrolimus 0.1% (M + T) Ointment versus Tacrolimus monotherapy 0.1% (T) Ointment in patients with stable vitiligo. The randomized, open label, comparative, prospective, multicentre study in patients with stable vitiligo was conducted. The primary endpoint was improvement in extent of repigmentation in target lesion after 12 months of treatment from baseline. The secondary endpoints were extent of repigmentation at end of 6 months, patient global assessment (PGA) and safety at end of 6 months. This shows interim analysis results. Total 94 patients were randomized to M + T (n = 40) and T (n = 44), 10 patients were lost to follow up. Extent of repigmentation (>50%) was significantly greater at end of 8 weeks in M + T group 22.5% (p ≤ .05) while 6.8% in T group. In grade of repigmentation, significant difference (p ≤ .05) was observed, M + T had better grade. PGA was significantly greater (p ≤ .05) in M + T-group than T. All these parameters showed significant improvement in M + T-group than group T at end of 6 months. No adverse events were reported during the study. It is an interim analysis report so complete data is not available for analysis. Addition of bFGF related decapeptide solution to Tacrolimus gave better results than Tacrolimus alone therapy. It also has a favorable safety profile and was well tolerated., (© 2019 Wiley Periodicals, Inc.)
