Nucleocapsid Antigenemia in Patients Receiving Anti-CD20 Therapy With Protracted COVID-19

Open Forum Infect Dis. 2022 Aug 17;9(8):ofac419. doi: 10.1093/ofid/ofac419. eCollection 2022 Aug.

Abstract

Immunocompromised patients with prolonged coronavirus disease 2019 symptoms present diagnostic and therapeutic challenges. We measured viral nucleocapsid antigenemia in 3 patients treated with anti-CD20 immunotherapy who acquired severe acute respiratory syndrome coronavirus 2 infection and experienced protracted symptoms. Our results support nucleocapsid antigenemia as a marker of persistent infection and therapeutic response.
