Successful treatment of persistent and severe SARS-CoV-2 infection in a high-risk chronic lymphocytic leukemia patient using Ronapreve™ antibodies.

Patients with lymphoproliferative diseases are at an increased risk of an incomplete immune response following vaccination or SARS-CoV-2 infection and might develop persistent viral infection and severe COVID-19 disease. We present a case of successful treatment of persistent and mechanical-ventilation-requiring SARS-CoV-2 infection in a del17 CLL patient using exogenous antibodies.
