Abstract

The development of antibody responses to SARS-CoV-2 is an indicator of seroprevalence and may afford protection from infection. It has been presumed that antibody responses to SARS-CoV-2 will be impaired in patients with aggressive haematological malignancy (PHM) due to underlying immunological dysfunction caused by malignancy or systemic anti-cancer treatment (SACT), placing them at increased risk. Here we analysed longitudinal serum samples from ten hospitalised PHM with aggressive disease and on SACT, collected up to 103 days post-onset of COVID-19 symptoms. We found that the majority (8/9) of PHM with confirmed SARS-CoV-2 infection seroconverted and developed antibodies to the major SARS-CoV-2 antigens (S1 and N) with most (6/8) produced neutralising antibody responses. Furthermore, the dynamics of antibody responses were broadly similar to that reported for the general population, except for a possible delay to seroconversion. Our finding that PHM on SACT can make functional antibody responses to SARS-CoV-2 has important implications for patient management and serological monitoring of SARS-CoV-2 in high-risk groups.

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding.
