Whilst some exhibit spontaneous recovery, others have experienced a more protracted disease length. Previous reports have described successful use of convalescent plasma, however there is a paucity of information around the use of the REGN-COV2 antibody cocktail in these patients. Case report: A patient with XLA was admitted to hospital with COVID-19 and remained persistently symptomatic with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) swab positivity despite treatment with Remdesivir and dexamethasone. Attempts at modulating the immune response with anakinra were unsuccessful. Consent for compassionate use of REGN-COV2 was obtained with administration taking place on day 87 of his illness. This was followed by a period of convalescence and SARS-CoV-2 nasopharyngeal swab negativity. As a consequence of prolonged immunosuppression, the patient developed pneumocystis pneumonia. Conclusion: This case highlights the role of antibodies in clearing SARS-CoV-2 in a hypogammaglobulinaemic host and demonstrates the consequences of prolonged immunosuppression and delayed treatment. We propose that this may be of particular significance given the capacity of SARS-CoV-2 to develop advantageous mutations in a chronically infected host. date: 2021-11-01 date_type: published publisher: Elsevier BV official_url: https://doi.org/10.1016/j.clinpr.2021.100089 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1888265 doi: 10.1016/j.clinpr.2021.100089 medium: Print-Electronic pii: S2590-1702(21)00026-1 lyricists_name: Goodman, Anna lyricists_id: ALGOO97 actors_name: Goodman, Anna actors_id: ALGOO97 actors_role: owner funding_acknowledgements: MC_UU_00004/04 [Medical Research Council] full_text_status: public publication: Clinical Infection in Practice volume: 12 article_number: 100089 event_location: England issn: 2590-1702 citation: Nguyen, H; Salkeld, J; Agarwal, S; Goodman, A; (2021) Compassionate use of REGN-COV2 in the treatment of COVID-19 in a patient with impaired humoral immunity.
