Article Synopsis
- The study explores how patients on immunosuppressants (ISPs) respond to SARS-CoV-2 infections compared to healthy controls, particularly looking at antibody levels post-infection.
- Patients with immune-mediated inflammatory diseases (IMIDs) on different ISP therapies showed variable antibody responses, with those on anti-CD20 and sphingosine-1 phosphate therapies having lower antibody levels.
- Despite lower antibody titers, the breakthrough infections in these patients were mostly mild, indicating that ISPs may not severely impede the overall immune response to SARS-CoV-2.
Background: Patients with immune-mediated inflammatory diseases (IMIDs) on immunosuppressants (ISPs) may have impaired long-term humoral immune responses and increased disease activity after SARS-CoV-2 infection. We aimed to investigate long-term humoral immune responses against SARS-CoV-2 and increased disease activity after a primary SARS-CoV-2 infection in unvaccinated IMID patients on ISPs.
Methods: IMID patients on active treatment with ISPs and controls (i.
For patients with immune-mediated inflammatory diseases (IMIDs), concerns exist about increased disease activity after vaccination. We aimed to assess changes in disease activity after SARS-CoV-2 vaccination in patients with IMIDs, and determine risk factors for increased disease activity. In this substudy of a prospective observational cohort study (Target-to-B!), we included patients with IMIDs who received a SARS-CoV-2 vaccine.

- - The study investigates how specific immunosuppressive therapies affect the immune response to SARS-CoV-2 vaccination in patients with immune-mediated inflammatory disorders, focusing on the humoral immune response.
- - Conducted in the Netherlands with over 3,200 participants, the research compares the immune responses of patients on immunosuppressants to controls, including healthy individuals and those without systemic immunosuppressants.
- - Findings indicate that certain immunosuppressive treatments, like anti-CD20 therapy and S1P modulators, result in lower chances of achieving adequate immunity post-vaccination, regardless of the type of immune disorder present.
