Considering the critical role of B cells in the adaptive immune response, this sounds quite correct.2 Even the data on interleukin 6 and tumour necrosis factor (TNF) inhibitors appear quite understandable considering the systemic inflammation raised by SARS-CoV-2 infection, the results of the Randomised Embedded Multifactorial Adaptive Platform for Community-acquired Pneumonia (REMAP-CAP) trial in patients on National Institute of Allergy and Infectious Diseases ordinal scale (NIAID)-Ordinal Scale 6 and 73 and the demonstrated role of TNF–TNF receptor 1 in inducing lymphopenia and T-cell dysfunction in severe–critical disease.4 Importantly, the death rate in abatacept was found close to that in JAK inhibitors.
