ABSTRACT
Patients with ANCA-associated vasculitis (AAV) cause extreme alertness during the coronavirus disease 2019 (COVID-19) pandemic, associated with many factors: the initial damage to the respiratory system (upper respiratory tract, lungs) and kidneys, immunosuppressive treatments, difficult prognosis of COVID-19 with the risk of AAV exacerbation. We present a clinical case of a moderate COVID-19 in a patient with granulomatosis with polyangiitis, who received anti-B cell therapy with rituximab (RTX) for a long time. Coronavirus pneumonia developed one year after RTX, while B-lymphocyte depletion persisted. In order to achieve an adequate antiviral immune response and prevent hyperinflammation, treatment was carried out with antiviral drugs, anticoagulants, convalescent plasma, human normal immunoglobulin, and interleukin-6 antagonist tocilizumab. Possible predictors of severe COVID-19 in patients with AAV are discussed.Copyright © 2023 Ima-Press Publishing House. All rights reserved.
