Key clinical point: Humoral response to BNT162b2 mRNA SARS-CoV-2 vaccine was reduced in patients with psoriatic arthritis (PsA) who received immunomodulatory treatment with antitumor necrosis factor (TNF) therapy, methotrexate, or interleukin 17 inhibitor compared with those without PsA.
Major finding: The median anti-SARS-CoV-2 spike receptor-binding domain immunoglobulin G (IgG) antibody level after 3 weeks of receiving the second dose of BNT162b2 mRNA SARS-CoV-2 vaccine was significantly higher in individuals without vs. with PsA (1,562.00 vs. 928.00 binding antibody units (BAU)/mL; P ≤ .001). The levels were, however, similar across anti-TNF therapy, secukinumab, or methotrexate treatment groups ( P = .73).
Study details: Findings are from a prospective study including 110 patients with PsA in clinical remission who received immunomodulatory treatment and were matched with 96 healthy healthcare workers, all of whom had previously received two shots of the BNT162b2 mRNA SARS-CoV-2 vaccine.
Disclosures: The study did not report any source of funding. The authors declared no conflict of interests.
