The international EAACI/GA²LEN/EuroGuiDerm/APAAACI guideline for the definition, classification, diagnosis, and management of urticaria

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 (GA(2)LEN) 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

Epidemiologia da alergia ocular e comorbidades em adolescentes

OBJETIVO: A prevalência de conjuntivite alérgica (CA) não foi estabelecida. Estimativas sugerem que alergias oculares afetam de 15 a 20% da população mundial, ainda que a maioria dos estudos epidemiológicos abranjam sintomas de alergia nasal e ocular e não sejam específicos a respeito da CA. O objetivo deste estudo foi verificar a prevalência de sintomas, comorbidades e o impacto da alergia ocular em adolescentes. MÉTODOS: Os adolescentes foram selecionados de uma amostra de escolas e preencheram, em sala de aula, um questionário previamente validado sobre os sintomas da CA. O seu diagnóstico foi considerado quando mais de três episódios de prurido ocular foram relatados nos últimos 12 meses. Sintomas relacionados, como lacrimejamento, fotofobia, sensação de corpo estranho, impacto sobre as atividades diárias e diagnóstico de conjuntivite alérgica, foram analisados. RESULTADOS: Foram obtidos questionários de 3.120 adolescentes (média de 13,3±1,1 ano). Nos últimos 12 meses, 1.592 (51%) adolescentes tiveram prurido ocular. O sintoma relacionado mais frequente foi lacrimejamento (74%), seguido de fotofobia (50,1%) e sensação de corpo estranho (37,1%). A prevalência de conjuntivite alérgica foi de 20,7%, afetando mais pessoas do sexo feminino do que do masculino (56,1% em comparação a 45,9%; p = 0,01). O risco de um adolescente com alergia ocular apresentar asma, rinite e eczema atópico foi (RC = 5,7; IC de 95%: 4,5 a 7,1); (RC = 3,6; IC de 95%: 3,0 a 4,3) e (RC = 2,6; IC de 95%: 2,0 a 3,5), respectivamente. Uma interferência grave nas atividades diárias foi relatada por 30,5%. CONCLUSÕES: Sintomas de alergia ocular são comuns, frequentemente relacionados a outras doenças alérgicas, e causam impacto sobre as atividades diárias de adolescentes
