Management of COVID-19 in immunocompromised patients: an European Society of Clinical Microbiology and Infectious...

Data on treatment of COVID-19 in immunocompromised patients emerged recently; however, published guidelines for the management of COVID-19 in immunocompromised patients are lacking.

To develop consensus statements derived from evidence and expert opinion on management of COVID-19 in immunocompromised patients, an expert panel was convened by European Society for Clinical Microbiology and Infectious Diseases. The expert panel developed a list of questions which are of general interest for clinicians and readers with backgrounds in clinical microbiology and infectious diseases. Six questions were selected. For each question, systematic literature searches were undertaken. We considered most study types, including clinical trials, observational studies with or without a control group, systematic reviews, case series, and case reports. Detailed inclusion criteria were defined for each research question using the Population Intervention Comparison Outcome format. Immunocompromised patients included patients with (a) primary immune deficiencies; (b) active malignancy or malignancy diagnosed or received cancer therapies within 1 year of COVID-19 diagnosis, (c) HIV with a CD4+ T-lymphocyte count <200 cells/mm³ or percentage <14%; (d) receipt of solid organ transplant within 1 year of COVID-19 diagnosis; (e) receipt of haematopoietic cell transplant or chimeric antigen receptor T-cell therapy within 1 year of COVID-19 diagnosis; (f) receipt of systemic corticosteroid therapy with a dose of ≥20 mg prednisone or equivalent daily for ≥14 days or a cumulative dose of >600 mg of prednisone; (g) receipt of biological immune modulators; or (h) receipt of disease-modifying antirheumatic drugs or other immunosuppressive drugs. The panel's consensus statements were based on evidence, supplemented by experience and expert opinion, especially in cases when evidence was limited or scarce.
