Intractable COVID-19 and Prolonged SARS-CoV-2 Replication in a CAR-T-cell Therapy Recipient: A Case Study.
2021
A CAR-T-cell recipient developed severe COVID-19, intractable RNAemia, and viral replication lasting >2 months. Pre-mortem endotracheal aspirate contained 2x10 10 SARS-CoV-2 RNA copies/mL and infectious virus. Deep sequencing revealed multiple sequence variants consistent with intra-host virus evolution. SARS-CoV-2 humoral and cell-mediated immunity were minimal. Prolonged transmission from immunosuppressed patients is possible.
