Behçet's patients' response to COVID-19 vaccination

Abstract

Immune hyperstimulation by SARS-CoV2 results in multi-system involvement with consequent organ damage not dissimilar to Behçet's Disease (BD). Management of BD includes immunosuppressive medication, which led to concerns that; firstly, SARS-CoV-2 would stimulate BD activity, thrombin, clotting times, TPO antibodies, and the effectiveness and duration of the COVID-19 vaccines' response in this potentially vulnerable group. The main objectives of this study were: to assess BD patients' immune response to the COVID-19 vaccines based on age, gender, disease activity, BD phenotype, and immunomodulatory medication compared to healthy control participants by measuring anti-spike IgG levels. Further to evaluate the effect of the COVID-19 vaccines on T and B cells, immunoglobulins, thrombophilia, thyroid function and COVID-19 antibody production. Patients on immunosuppressive medication had a reduced immune response to COVID-19 vaccines. -Also, patients over 40 years and with the neurologic BD phenotype had lower responses. mRNA COVID-19 vaccines were more effective and had fewer side effects compared to conventional COVID-19 vaccines.
