Chronic Spontaneous Urticaria After New Coronavirus Infection: Clinical Cases

Background . Inefficacy of conventional chronic spontaneous urticaria (CSU) treatments significantly reduces patients’ quality of life. Data on CSU (triggered by new coronavirus infection) prevalence and course in children is very limited. Clinical case description . Authors have presented three clinical cases of CSU onset after the new coronavirus infection. Clinical features of disease and targeted therapy efficacy were evaluated. Conclusion . T he course of CSU, potentially triggered by SARS-CoV-2, has its own features, and requires larger research with the study of clinical and laboratory aspects, as well as the immunological mechanisms underlying the disease, with revealing biomarkers indicating disease severity, course, and prognosis.
