Urticaria is characterized by pruritic wheals of the skin’s superficial layers, which occurs for six weeks or longer, with no apparent cause. It is a condition that reduces the quality of life of the patient and may have a significant economic and social burden. The objective of this revision was to review the guidelines for urticaria management.

According to the joint initiative of the EU-founded network of excellence, the Global Allergy and Asthma European Network, the European Academy of Allergology and Clinical Immunology, the World Allergy Organization, and the European Dermatology Forum, management of urticaria should be done in a stepwise manner. Second-generation H1-antihistamines are considered first-line treatment. Whenever symptoms are not adequately controlled, treatment should follow the algorithm. This algorithm includes an increase of the dose of second-generation H1-antihistamines, alongside first-generation H1-antihistamines, H2 antagonists, omalizumab, ciclosporin A, or short-term corticosteroids if needed. New treatments on development include spleen tyrosine kinase inhibitor, Bruton tyrosine kinase inhibitor, prostaglandin D2 receptor inhibitor, H4-antihistamines, and biologics. Alternative agents include leukotriene receptor antagonists, anticoagulant and antifibrinolytic agents, antidepressants, vitamin D, and other anti-inflammatory or immune-suppressing agents.

According to the authors, second-generation H1-antihistamines should always be considered the first-line therapeutic option for urticaria management. For those who do not respond to a higher dose of H1-antihistamines, guidelines recommend adding omalizumab. Well-designed trials are required to draw clear conclusions.

The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV2), has resulted in an increased healthcare burden, with different symptoms manifesting in other patients. The evidence of skin manifestations similar to urticaria is also growing. The objective of this systematic revision was to review the current literature on urticaria in COVID-19 patients.

According to PRISMA guidelines, investigators carried out an extensive literature search in Medline, EMBASE, Scopus, Cochrane, and Google Scholar, using “COVID-19”, “Coronavirus”, “SARS-CoV-2”, “urticaria”, “angioedema” and “skin rash” until August 2020. Articles related to urticaria and/or angioedema due to COVID-19 and its management and outcome were included.

From the 169 articles returned by the search, 25 of them met the inclusion criteria. These articles were case reports, which related 26 patients infected with SARS-CoV-2 with symptoms such as urticaria and/or angioedema. Most patients (69%, n = 16) were over 50 years old. Treatment with antihistamines and/or steroids resolved the symptoms in different time frames, from less than 24 hours to up to 2 weeks. There was no report of recurrent cases of urticaria or non-responsiveness to treatment.

Patients infected with SARS-CoV-2 who develop urticaria symptoms should be managed with antihistamines. The use of a low prednisolone dose should be evaluated according to each patient in the shortest duration possible until symptoms are controlled.

Chronic spontaneous urticaria is a chronic disease characterized by wheals and pruritus and/or angioedema. Most urticaria patients are women who have their quality of life reduced due to the impact of the disease on daily life and sleep quality. Fatigue is a common symptom in urticaria. This study’s objective was to assess fatigue and how it affects people with chronic spontaneous urticaria compared to healthy people.

This study included 103 patients with chronic spontaneous urticaria and 35 age and gender-matched healthy controls. They were assessed for fatigue with the Fatigue Severity Scale (FSS) and VAS-Fatigue. Duration, activity, and control of disease, as well as anxiety, depression, and quality of life, were also evaluated.

No significant associations were seen in disease activity, disease control scores, FSS, positivity for anti-nuclear antibodies, and IgE levels between fatigued and non-fatigued patients with urticaria. Fatigued patients had significantly higher CRP levels (p=0,009). Also of note was the significant correlation between total FSS score and chronic urticaria quality of life in patients with chronic spontaneous urticaria, where women with urticaria and with disturbed sleep complained of fatigue.

Women with chronic spontaneous urticaria commonly experience fatigue, which is an important symptom that negatively affects their quality of life.
