Treatment of persistent COVID-19 in two B-cell-depleted patients with the monoclonal antibody Sotrovimab

Abstract:

Background: Patients having undergone B-cell-depletion with anti-CD20-antibodies have a higher risk of mortality, delayed viral clearance and prolonged infection due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We report two cases of patients with persistent coronavirus disease 2019 (COVID-19) in association with B-cell-depletion that were treated with the monoclonal antibody Sotrovimab.

Case presentation: Both patients presented with chronic symptoms of COVID-19 such as dyspnea, fatigue, and chest pain. Nasopharyngeal swabs remained positive months after the initial infection with fluctuating cycle threshold (Ct) values around 30. Both patients received a single infusion with the monoclonal SARS-CoV-2 antibody Sotrovimab, which resulted in a rapid improvement of symptoms and inflammation markers as well as negative SARS-CoV-2 swabs. A follow-up after a month showed ongoing improvement of symptoms, persistent negative SARS-CoV-2 swabs, and positive serum antibodies.

Conclusion: Infusion with the monoclonal SARS-CoV-2 antibody led to rapid improvement in two patients with persistent COVID-19 after B-cell depletion.
