medRxiv (Cold Spring Harbor Laboratory)(2022)
Abstract
AbstractIntroductionAlthough there are case reports and guideline recommendations that states omalizumab can be used in chronic spontaneous urticaria (CSU) patients during SARS-CoV-2 pandemic, there are scarce studies showing the course of Coronavirus disease 2019 (COVID-19) in CSU patients receiving omalizumab.Materials and MethodsA total of 370 patients with chronic urticaria were included in the study between June 2020 and December 31, 2020.ResultsSixty patients (16.2%) became infected with the SARS-CoV-2. The rate of pneumonia and hospitalization were 4.1% and 1.9%. There was no significant difference was determined between the CSU patients with omalizumab treatment and the non-receivers in regard to the rate of SARS-CoV-2 (+) (p: 0.567) and in regard to the rate of SARS-CoV-2 related pneumonia and hospitalization (p: 0.331 and p: 0.690). Gender, duration of CSU, serum IgE levels, omalizumab treatment, and atopy were not found to be associated with an increased risk for SARS-CoV-2 positivity in patients with CSU.ConclusionOur study shows that the use of omalizumab does not increase the risk of COVID-19 infection, COVID-19-related pneumonia and hospitalizations in CSU patients and supports the views that omalizumab can be used safely in patients with CSU during the COVID-19 pandemic.
