- Published on: 16 May 2022‘Correspondence on “Two-week methotrexate discontinuation in patients with rheumatoid arthritis vaccinated with inactivated SARS-CoV-2 vaccine: a randomized clinical trial” by “Araujo CSR et al”‘.
We read with great interest the recent article written by Araujo CSR et al entitled “Two-week methotrexate discontinuation in patients with rheumatoid arthritis vaccinated with inactivated SARS-CoV-2 vaccine: a randomized clinical trial” published in the Annals of Rheumatic Diseases on February 22, 2022 [1]. The major impact of this trial was the reinforcement of the immunogenic effect of a 2-week methotrexate discontinuation after each dose of the Sinovac-CoronaVac vaccine against SARS-CoV-2 compared to methotrexate continuation in patients with rheumatoid arthritis (seroconversion rates: 78.4% vs 54.5%, p-0.019 and geometric mean antibody titers: 34.2 (25.2–46.4) vs 16.8 (11.9–23.6), p=0.003, respectively).
Previous experience with other non-COVID-19 vaccines, like the influenza or pneumococcal vaccines, has indicated that discontinuation of immunosuppresants improves the immunogenicity of a given vaccine [2,3]. Based on this knowledge, we had proposed that it would be beneficial for patients with autoimmune rheumatic diseases to get vaccinated against SARS-CoV-2 preferably when the underlying rheumatic disease is in remission and after temporal withdrawal of anti-metabolites within 10 days before and after each vaccine dose along with similar modifications in anti-cytokine drugs and corticosteroid dosages >10mg/ day (prednisone equivalent) [4]. In fact, applying that in a comparative study it was shown that the magnitude of antibody responses to mRNA-based S...
